What are looms? Water retting seemed to take less time and the fibres were brighter and more uniform, than those achieved with dew retting. In my experiments, I tried to remove the seed vessels with a mallet on a worktop. The process of making yarn from fibre is called spinning. Decorticated kenaf stalks were retted by bacterial and chemical processes. Mittelalterliche Flachsdarren, Experimentelle Archäologie: Bilanz 2001. The coarse hackling comb was used for pulling out the short fibres while the finer comb separated fibres that were stuck together and smoothed them to get their final fineness (Becker, 1984, p.8; Schmitz, 1975, pp.9-11). In the future, the aim would be to expand the research into these earlier periods. The short handle club is worked with flax gathered in bundles on a worktop. 0. It is used to produce cloth on large scale in cloth producing industries. Flachs und Leinen zwischen Leine und Weser. DRAFT. It is done in the field, taking advantage of the natural elements of dew, rain and sun, or under controlled conditions using water, enzymes or chemicals. The goal of scutching is to remove the last remaining parts of the woody material from the fibrous layers. On its surface, linen production research is simple as there is a large corpus of books available; however, the majority of these date to the last three centuries. It is harvested about 100 days later. I used a large water tub for my experiments. 1. The third method works by drawing the flax through a ‘Rippler’, which is a coarse comb that peels the seed vessels from the stems. Überlegungen zu einer Ofenform. Heidelberg. I have tried to break the flax with a wooden club and it works, but restricted that to splitting the stems lengthwise and the work takes longer. Fiber tenacity tests indicated that the extractive removal of pectin from pseudo-stem fiber through retting did not cause any significant change in the tenacity of the fiber except when over-retting had begun. Oye, I., 1988. In the Middle Ages, probably only one plant was cultivated that provided both (Knöchel and Vogeler, 2001 p.115). Cotton is also used to make some artificial fibres like rayon. Tomasek, T., 1996. Hope this information will clear your doubts about the topic. The water retting is done for a period of 5 days reducing the non fibrous content in PALF by about 25% and the resultant fibre is found to have a linear density of 2.26 tex and an average linear density of about 3.8 tex after microbiological retting. Körber-Grohne, U., 1987. Basic methods include dew retting and water retting. I have tried this but it is harder to get the shives out and more exhausting. Retting and microbial action on the plants will help dissolve the pectin and lignin that hold the fibres in the plants. to soak in water or expose to moisture, as flax or hemp, to facilitate the removal of the fiber from the woody tissue by partial rotting. A similar tool has been found in Novgorod/ Russia, but it cannot be determined whether or not its use was for flax working (Kolchin, 1989, pp.28, 256, Figure 4). Westfalen-Lippe. She sits in front of a tree trunk with multiple rows of long prongs, and she is pulling long fibres through the prongs. Köln. So far I have only worked on small amounts of hemp, but the process works well even though it takes longer. For example, in Bryggen (Bergen, Norway) archaeologists have recovered wooden combs during excavations (Oye, 1988, p.29). 2, Norwegian University Press. Wunderlich, W., 1996. Volkskunde, Veröffentlichungen des Braunschweiger Landesmuseums, 43, Braunschweig. High concentrations of lime prevent retting (Linke, 1982, p.20; Fasse, 1989, p.25; Birkigt-Quentin, Busse and Schäfer, 1995, p.9). A single yarn is used to make a piece of fabric is: (a) gimming (b) spinning (c) weaving (d) knitting. The traditional methods for separating the long bast fibres are by dew and water retting. The longer willow handle club was used by several men on flax bundles laid on a prepared floor. The plant was introduced to Cuba in the 19th century and became the country’s chief fibre crop by Heimberger, H., 1957. Cramer, T., 1998. The flax stems were often broken immediately after being removed from the oven, which gave them names such as “breaking pit “or “breaking” oven (Harzheim, 1989, p.21). "retting" which separates the fibre from the decaying part of the plant. Statement 2: The process of retting softens the tissues and helps to separate the fibres. In the retting process the pectin, the so-called vegetable glue that surrounds the fibres, is dissolved by either bacteria (water retting) or by fungus (dew retting). The process of Retting is done to obtain Preview this quiz on Quizizz. Pectin, while often low in amounts, is strategically located and binds cell walls within plants . While the fibres of the earlier harvests were indeed finer, they also tended to be harder to extract especially close to the tips of the stem. Weaving: The process of making fabric by crossing two sets of yarns over and under each other is called weaving. Retting is a process employing the action of micro-organisms and moisture on plants to dissolve or rot away much of the cellular tissues and pectins surrounding bast-fibre bundles, and so facilitating separation of the fibre from the stem. 6th grade. Older texts, while available, tend to concentrate on the textiles themselves and their trade. Using this method, the flax could be extracted more easily from the bast. Berlin. The hot and dry month of August is perfect for drying the flax after the harvest and for dew retting. Vegetable Dyes Being a Book of Recipes and Other Information Useful to the Dyer. 62, Basel, pp.2262-2273. Retting is the main challenge faced during the processing of bast plants for the production of long fibre. Chemical retting is more expensive and does not produce the superior quality fibre obtained from the biological retting process. Email: info@exarc.net, EXARC Facebook Page With this method, the fibres are stained dark grey by mildew and therefore must be bleached. Delaying the harvest too long will result in woody stems and unusable fibres. (iii) The cotton plant requires warm climate. Again, the greatest disadvantage is dependency on the weather. Becker, B.D., 1984. The clubs have a flat head with either a short handle or a longer elastic handle made from willow. Vom Flachs zum Leinengarn, Münster. This medieval comb is almost identical to a 19th century hackling comb in the author’s possession. The Kunkel house fresco shows a woman who is probably scutching and labelled “Thesens”, which is somehow connected to scutching (Wunderlich, 1996, pp.53-54). However, hemp has very fine fibres at the centre of the stem (Körber-Grohne, 1987, p.383). Hemp and nettle can be used to make linen like cloth and the steps for flax and hemp processing do not differ much. 6. • The net income is increased by at least Rs. Linz. Herausgeber Fansa, Mamoun, Oldenburg, pp.103-136. Traductions de mot RETTING du anglais vers français et exemples d'utilisation de "RETTING" dans une phrase avec leurs traductions: Straw color or degree of retting . Explain how fibres are obtained from the jute plants. This is industrially done with pairs of rotating rollers, which crush the shives. Retting may be carried out in one of several ways. In this process, fibres from a mass of cotton are drawn out and twisted. Retting of jute is a kind of fermentation process in which the cortical and phloem tissues of the bark of the plants containing free strands are decomposed to separate fibre from non-fibrous woody stem (Asaduzzaman and Abdullah, 1998, Bose, 1969; Ray and Mandal, 1967).The fermentative microorganisms consume the cementing materials viz., the pectins, hemicelluloses and … However, the traditional extraction of coconut fibre from coconut husks (Retting) causes significant negative impact on the environment. Waz hilfet ane sinne kunst?. by ritaranipanigrahy_91662. In this process fibres from a mass of cotton wool are drawn out and twisted. Ceramic analysis and radiocarbon dating gives a date of around 400 AD (Seegschneider, 2005, pp.145-146). This process is called ‘retting’. When a single yarn is used, the fabric is prepared by knitting. In addition, my first attempt at dew retting was in October 2014 in Northern Germany, when it was probably already too cold with daytime temperatures around 16-18 degrees. Fibre to fabric DRAFT. Traditionally this has been done in the same way as Flax and Hemp, i.e. Both methods require 14 to 28 days to degrade the pectic materials, hemicellulose, and lignin. The Hungarian National museum exhibited a 13th century comb excavated in the 1950s from a former medieval village. Wooden artefacts from medieval Novgorod, Illustrations. China also has a dominating place in jute cultivation. Heat setting is also known as ANNEALING. Researchers would like to replace this rather haphazard method by further developing enzyme retting, which would use selected pectin-degrading enzymes to ret the straw under controlled conditions. A fire was lit in one pit, and through a tunnel, smoke and heat were conducted into the other pit, above which the flax was placed on a grid to dry. The cut plants are grouped at different places in the field for a few days when most of the leaves dry up and fall down. Retting of fibres is caused by [JIPMER 1987] A) Bacillus B) Clostridium C) Nitrobacter D) Rhizobium Ask for details ; Follow Report by Sundarallu563 05.01.2018 Log in to add a comment Answers CaptainBrainly Genius; HEYA!!! 0 times. However there are no illustrations or depictions until the break becomes widespread in the Late Middle Ages. The body of the club was mostly made from apple, walnut or ash (Dewilde, 1999, pp.81-82; Scheuermeier, 1956, p.233). An observation I had was that the batches using rain water rather than tap water achieved better results. Flachs und Leinen. For smoothing, a piece of leather is placed on the thigh and the fibres are worked with a smoothing knife. Iron combs, set in wooden beams are apparently known from at least the High Middle Ages. In: Sammlung zur Volkskunde in Hessen, 14, Der bäuerliche Alltag 1, Flachsverarbeitung, Otzberg, pp.16-22. Inside the plant, flax fibres are arranged in a circle around the central core of the stem. One woman is shown smoothing and has clearly visible a piece of leather placed on her thighs and a smoothing knife. If the weather is bad, it can take a very long time for the flax to dry or, in the worst case, the whole harvest is lost. This can either be done by water retting, where the plant stems are soaked in lakes, rivers or waterlogged pits, or by field retting, where the stems are laid out in a field in order to absorb dew. During smoothing, the fibres are not only aligned but also smoothed with very fine silky fibres produced (Fasse, 1989, p.37). Prehistoric Methods in Antler Working, Discussion: Experimental versus Experiential Archaeology, Publishing Archaeological Experiments: a Quick Guide for the Uninitiated, Creative Commons Attribution Non-Commercial 4.0 License. Depending on the weather, dew retting takes approximately three to five weeks. The difficulty with the nettle is extracting the fibre from the stems. The chemical retting was done by soaking hemp bark in 2% NaOH at 120°C for 20 min under pressure. Nutzpflanzen in Deutschland. Therefore, it was better to work with two pits. Frambozenweg 161 The fibres were pulled off the stem by hand, starting at the root and the bast was removed from each stem individually (Gerig, 1913, p.40). The hackling comb itself has the shape that has survived to today. I have grown and processed flax in a small open-air museum since 2014, and have been able to produce high quality fibre in 2016 and 2017. However the last remains of the shives can be removed effectively and the fibres loosened and aligned. The German name of “Dutch breaking chair” suggests the break being invented by the Dutch (Dewilde, 1999, p.155). Bread ovens, either private or communal, could be used, although there was a high fire risk as the dry flax is highly flammable. Vom Flachs zum Leinengarn. Comments; Report Log in to add a … Statement 1: After harvesting, the stems of the Jute plants are tied into bundles and retted (soaked) in water for about 20 days. The plants are now tied into small bundles. Bacterial retting was done in troughs at a temperature of 30 ± 2°C. The seeds will ripen while the flax is drying after the harvest. • Retting is completed within 7-9days in comparison to 18-21 days required under conventional whole plant retting. Die mittelhochdeutschen Lieder vom Flachsschwingen. Early Egyptian wall paintings show the flax plant being harvested by pulling the plant out of the ground root (Klebs, 1915, pp.54-55) and all, a practice that has survived to today. Initially the stems are worked with a wooden club or mallet, to break the woody parts of the outer hull and core. Fibres are drawn out and twisted. Schaefer, G., 1944. Question 4. When two sets of yarn are involved, yarns are woven on looms to make fabric. Retting is a microbial process that breaks the chemical bonds that hold the stem together and allows separation of the bast fibers … Flax (summer flax) is an annual plant usually sown in mid-April when there are the best conditions for growing with sufficient rainfall. They protect us from foreign, harmful substances falling on our body. Answer (d) knitting A single yarn is used to make a piece of fabric is knitting. Henequen fibre is an important leaf fibre and has been used since pre-Columbian times. Vom Flachs zum Leinen. The retting lasted about 10 days longer than in later tests in August 2015 and 2016 at temperatures between 25 and 30 degrees Celsius. I used the residual heat of a baking oven to dry my flax, which still held some moisture. The short fibres combed are called tow and can be carded by hand and spun as well. 10 hours ago. (iv) Jute is mainly cultivated in Bihar, Assam, Odisha, Andhra Pradesh, West Bengal, etc. (i) Fibres obtained from natural resources are called natural fibres. Summer flax’s early sowing season means it is harvested at the end of July or the beginning of August. It is now possible to trace all the work steps and associated tools used in the Middle Ages. Solving the Fibre to Fabric Multiple Choice Questions of Class 6 Science Chapter 3 MCQ can be of extreme help as you will be aware of all the concepts. You must have JavaScript enabled to use this form. (g) Polyester is a natural fibre. There are archaeological finds of wooden clubs from Bergen (Bryggen), that could have been used in flax processing that date back to the late medieval period, as well as finds from Novgorod (Oye, 1988, p.28; Kolchin, 1989, p.256). Cotton is useful to make bed sheets, curtains, upholstery, etc. In addition, industrial production of untreated hemp fibres cannot be done without damaging the fibres making the field retting the only alternative with much worse properties of 49 GPa and 0.162 for stiffness and porosity factor, respectively. The simplest dryers are made from a simple pit, where the flax is laid on a gridiron over a small fire, which was also a big fire hazard. (e) Silk fibre is obtained from the stem of a plant. When looking at the depiction by Glockendon, it suggests that it could be either breaking or scutching, whereas other depictions show more likely a step in breaking. If ‘boken’ is used as a preparation for breaking, then it makes the later step easier to accomplish. Retting is a process employing the action of micro-organisms and moisture on plants to dissolve or rot away much of the cellular tissues and pectins surrounding bast-fibre bundles, and so facilitating separation of the fibre from the stem. The frescos in house Zur Kunkel, Constance dating to the 14th century (Wunderlich, 1996, p.29) showed a different aspect to production of cloth. Properties Jute is a long, soft, shiny vegetable fibre that can be spun into coarse, strong threads. By retting the fibres they are softened and can be decorticated and extracted by beating 16, which is usually done by hand. My flax break is a reconstruction based on the depictions of Albrecht Glockendon, in a calendar from 1526, and the fresco in Saak. A foldable lever with an integrated V-track and handle is pushed down onto this board. This allows the … The chemical retting was done by soaking hemp bark in 2% NaOH at 120°C for 20 min under pressure. Aus Flachs wird Leinen. This action partially decomposes the husk's pulp, allowing it to be separated into coir fibers and a residue called coir pith. Stuttgart. Explain how fibres are obtained from the jute plants. Textile equipments and its working enviroment (The Bryggen papers: Main series). Retting plant material smells strongly! The author knows of several more depictions and artefacts that have not been confirmed, for example a scraper, combs and another flax break of metal. Von Flachs und Leinen in alter Zeit. Retting is a process employing the action of micro-organisms and moisture on plants to dissolve or rot away much of the cellular tissues and pectins surrounding bast-fibre bundles, and so facilitating separation of the fibre from the stem. During an event I had the chance to try out oven drying. The.dried fibres are then tied together in small bundles. The cut plants are grouped at different places in the field for few days when most of the leaves dry up and fall down. Hemp rope-making technology is also in the works at ATM, the company said. The State Museum in Braunschweig possesses a scutching sword, dated to the 13th century, that was found in downtown Braunschweig/ Germany. Save. 3.10). It is made from beech and looks like a broadsword, which is probably where the German name for this tool originated. retting, where a substantial portion of fibre is lost during retting and washing. Work with this break is fast and effective. Altes Hauswerk und Handwerk auf dem Lande Teil1 Die Flachsverarbeitung. Question 5. (i) Fibres that are manufactured artificially in factories using different chemicals are called synthetic fibres. Again, from House Zur Kunkel, this process is depicted and entitled as “riben” however, there is not a tool in the hands of the worker. Following retting, a sequence of processes to remove the fibres from the woody stalks is carried out first by breakingthem and then scraping or scutchingthem off which is done by beating with blunt wooden or metal blades either by hand or mechanically. Retting is the process of beginning to separate the bast fibres from the hurds or other plant tissues. Field retting is the most practical method of hemp fiber production for farmers in the US, but little research has been done on the microbiota associated with hemp stalks during field retting, or on applied practices that improve the quality and consistency of the fiber without substantially increasing cost. Exposure to … (d) Weaving of yam makes a piece of fabric. A machine is used for weaving of fabrics is: Warmer weather shortens the time, but if it is too dry, the flax must be sprinkled with water regularly as decomposition is achieved mostly by the fungal action. My experiments with this method were not very successful, though I may lack some information or just practice. Kalenderminiaturen der Stundenbücher. Kuhnert, R., 1920. Cotton oil is extracted from its seeds, which is refined to use as a cooking oil. The fibrous stem after retting has to be mechanically processed to extract of fibre of good quality. This causes a large amount of the woody outer hull to drop off. There is a similar artefact that dates from the Slavic period (600 to 1200 AD) on display in the State Museum in Brandenburg/ Germany. Ans. Winter-flax is sown in autumn and harvested the following year but this flax was rarely cultivated. This is only a short overview on flax fibre extraction in the Middle Ages. In addition, the fibre quality was not so good because the plants had grown lower due to the drought. The fineness depends an variety of pineapple and prosperity of the leave. Excavations during the building of the A20 motorway in Northern Germany, uncovered a 68 cm long wooden block with a lengthwise groove and a hole drilled through, possibly for the shaft of the lever. After 10 days of bacterial retting, the stalks were wa... Decorticated kenaf stalks were retted by bacterial and chemical processes. There is a photograph of a similar looking tool from Finland from 1922 (Kaukonen, 1946, p.80). Meulebeke Belgien. The combined effects of sun, rain and dew causes the stem to begin to decompose and become brittle. Jute is one of the important natural fibers after cotton in terms of cultivation and usage. A bundle of flax is placed between the upper and lower parts of the break and then struck with the upper section several times while slowly pulling the sheaf through. On the fresco, the hemp is broken by hand, which seems to be both difficult and ineffective. Website: EXARC.net For both methods of retting it is very important to end the retting at the right moment. Klebs, L., 1915. (d) The process of removing seeds from cotton is called ginning. LinkedIn Group: AOAM. Flax Fibre Extraction Techniques in the Late Middle Ages, Institutional Members Higher Education Centres, Institutional Members Groups & Associations, Registration Form for Institutional Members, The Steinzeitpark Dithmarschen (DE): Concept and Development of a Visitor Oriented Educational Centre for Sustainable Development, Experimental Archaeology in Latvia: some Possibilities for Future Development, Have you got the tine? However, due to the climatic changes in modern times, I had problems with drought in spring, especially the last two years, and the crop required watering. You do get a feeling and understanding of the process for the retting process very quickly. Linke, W., 1982. Answer: Jute plants are cut at the flowering stage when plants are 8-10 feet high. After retting, the woody core is broken into small pieces that can be separated from the fibers by decertification. Die Aufbereitung von Flachs und Hanf im Spiegel behördlicher Maßnahmen 1463 – 1882. Fibres are first converted to yarn by the process of spinning. Mittelalterliche Flachsdarren? Just the flax, ma'am. Methods of retting nettle fibres. Early Egyptian wall paintings depicted this process (Schaefer, 1944, p.2264) and it was also described in writings by Pliny, the Roman scholar, but not as a preliminary step but the actual breaking process. Terminologie der Hanf- und Flachskultur in den frankoprovenzialischen Mundarten. Today we distinguish two types of flax, for the extraction of linseed and for the extraction of fibre. (i) Jute fibre is obtained from the stem of jute plants. It consists of a large long heavy wooden block with a longitudinal groove, attached to a wooden frame. They protect us from harmful insects, bacteria and dirt, wind and injury. Cultivation is dependent on the climate, season, and soil. Several methods of removing seeds have survived in recorded history. Heat setting is a process of imparting dimensional stability of fibers or yarns with successive heating and cooling in dry and most condition. (iv) The process of removing hair from the sheep is called shearing. It is a board with a nail block placed on the knees (Schaefer, 1944, p.2268). 10 hours ago. Fibre is extracted from the retted jute by hand, with jerks and pulls. Ans. In order to achieve an even ret, the flax must either be laid so thin that the ground can still be seen, or if laid thicker must be turned from time to time. Lipp, F.C., 1989. The only change over time was the addition of extra v-shaped tracks and grooves. • The fibre quality is improved at least by 2 grades (from TD6 to TD4). Edit. This is unlikely to be an image of wool combs as they are normally depicted as pairs with only one or two rows. This can be done either chemically or by natural physical methods as follows: Retting is of two types: Water Retting: ATM said the development team is working to increase capacity of the machine, which bypasses the retting of hemp stalks in water, and can also strip away fiber from nettle and linen plants when adjusted. called retting 14. It is not left to dry flat on the ground, because there is a chance that retting would begin (Fasse, 1989, p.19; Kuhnert, 1920, p.75). 7. Die Reliefs des alten Reiches (2980 – 2475 . Das blaue Wunder. All these changes are connected with the structural & chemical modifications occurring in the fibres. Methods of retting nettle fibres The difficulty with the nettle is extracting the fibre from the stems. Of course, I didn’t reach the full yield, that a good ret would deliver. Jute fibres are composed primarily of the plant materials cellulose and lignin . In terms of yield, this should be about 10-15% of weight of the dried plant left as long fibres (Dambroth and Seehuber, 1988, p.87; Schilling, 1935, p.33; Flad, 1984, p.24). The broken stems are laid over an upright standing board, the scutching board, and then worked with a scutching knife (a flat usually narrow wooden board with a handle) to remove the shives. Freshwater retting is used for fully ripe coconut husks, and saltwater retting is used for green husks. But it is longer and is more dependent on the weather. This process is used for making shirts, trousers, T-shirts, etc. The author sets the step of smoothing after the hackling, which matches the depictions from the House Zur Kunkel. The retted fibres, being aggregates of elongated cells are still 9. After harvesting, it is kept submerged in water for a few days. Edit. It is somewhat difficult to find a fitting association. Ans. The devices on which weaving of fabrics takes place are called looms. with water or dew retting. Although my parents in law came from a family which had processed flax, this knowledge had not been passed down and as a result I had to learn by reading and through practical experience. Henequen, (Agave fourcroydes), fibre plant of the asparagus family (Asparagaceae), native to Mexico and Guatemala. The most notable fact is that the devices used in non-industrial fibre extraction remained essentially unchanged over many centuries, which indicates that these early techniques had proven themselves to be optimal. The plant’s taproot means the plant can be extracted from the ground easily and the full length of the plant fibres is available for processing. In the future, I would like to start here in order to achieve even better results and determine by measurements how much fibre yield I can achieve with the knowledge of flax processing that I have acquired myself. Making of Fabric, Fibre to Fabric, Class 6. This is a long and strenuous process, but a wonderful challenge, and there are no rules, unless you are an archaeologist trying to imitate historical methods. The pulled flax is set up in bundles, like little chapels, and left in the field to dry. The flax is pulled through the comb to remove shives and short fibres. Die wirtschaftliche Bedeutung der Flachspflanze. with water or dew retting. In a 13th century text by Gottfried von Neifen on the topic of flax processing: „si kann beidiu dehsen unde swingen“ (She can do both, breaking and scutching. Dewilde, B., 1999. Bäuerliche und handwerkliche Arbeitsgeräte in Westfalen, Aschendorf. If done correctly, the fibres can be extracted easily from the core. They make use of borehole water that is heated by solar power for their dye baths. The stems rot (the process is called retting) and fibres are separated by hand. It is the pectin-rich regions that are of prime importance in retting, and considerable work has been done on the pectinases and ways to degrade the pectin in flax. The hemp fibres are separated by ratting, which is the process of decaying pectin that binds the hemp fibres to the core of the stem.
