From the 15th century on, there were plenty of bans on letting flax ret in fishing waters (Reutter, 1979, p.16). Freshwater retting is used for fully ripe coconut husks, and saltwater retting is used for green husks. Iron combs, set in wooden beams are apparently known from at least the High Middle Ages. Oxford. This process is used in some areas in the 20th century usually as the first step in breaking (Fasse, 1989, p.29). The seeds will ripen while the flax is drying after the harvest. Rotenburg, Wümme. 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. It also brings changes in strength, stretchability, softness, dyeability & sometimes on the colour of the material. The flax is pulled through the comb to remove shives and short fibres. When the jute plant is in the flowering stage, it is harvested. Flachs und Leinen. Rate! Threshing, used with cereals, cannot be used as a method as it damages the stems. These finds suggest that the flax break, which have been preserved until the last century in the villages of northern Germany, date to the Early Middle Ages. Chr.). In the Odenwald region, there is written evidence dating from the 18th century that describe these types of structures being used to dry flax (Heimberger, 1957, p.254). The disadvantage of this method is the the damaging effect it has on the environment, as bacteria withdraws oxygen from the water potentially killing fish. For dew retting the flax is laid out on fields; harvested stubble fields or mowed grassland are well suited to this. 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). (d) The process of removing seeds from cotton is called ginning. This can be done either chemically or by natural physical methods as follows: Retting is of two types: Water Retting: The Hungarian National museum exhibited a 13th century comb excavated in the 1950s from a former medieval village. Inside the plant, flax fibres are arranged in a circle around the central core of the stem. It is very important however that the flax is broken directly after drying, otherwise the flax will absorb moisture from the atmosphere quickly, which is the reason why it is more difficult to break and scutch flax during days with high humidity. Gerig, W., 1913. My experiments with this method were not very successful, though I may lack some information or just practice. It is made from beech and looks like a broadsword, which is probably where the German name for this tool originated. The hackling comb itself has the shape that has survived to today. The clubs have a flat head with either a short handle or a longer elastic handle made from willow. Helsinki. (iii) Coir is obtained from fruits of Kapok tree. China also has a dominating place in jute cultivation. When the fiber is exposed to microbial action, it is weakened and, as a result, the breaking strength varies inversely with the length of the retting period. The first process is the retting of the plant stems to dissolve the pectin which fixes the fibres to the stalk. Both methods require 14 to 28 days to degrade the pectic materials, hemicellulose, and lignin. Scutching, as with breaking, is very exhausting work. The State Museum in Braunschweig possesses a scutching sword, dated to the 13th century, that was found in downtown Braunschweig/ Germany. Die Grabung Feddersen Wierde. This process is used for making shirts, trousers, T-shirts, etc. At later dates, there are several types of hackling combs. Although these archaeological finds lack the evidence of plant remains to clarify what was actually dried inside (Berthold, 1999, p.131). Edit. Scheuermeier, P., 1956. A pull-out hackling comb, which was very coarse was used for pulling out the branched flower stems, something that isn’t done everywhere. The body of the club was mostly made from apple, walnut or ash (Dewilde, 1999, pp.81-82; Scheuermeier, 1956, p.233). (i) Fibres obtained from natural resources are called natural fibres. However the last remains of the shives can be removed effectively and the fibres loosened and aligned. This method requires no tools and is impossible to determine where or if this method was used in the Middle Ages. They make use of borehole water that is heated by solar power for their dye baths. Retting of Coconut Fibre The environmental impact of coconut fibre production is small. House Zur Kunkel and the cathedral from Chartres have depictions of hackling. In lab-scale, the fibres are isolated with hand peeling. Heat setting. Bark was soaked in a tank of water for 9 weeks in the water retting process. • The net income is increased by at least Rs. (g) Polyester is a natural fibre. Another processing step, that has survived from at least the Middle Ages to the last century, but not used everywhere, is called smoothing. München. Knöchel, F. and Vogeler, U., 2001. Linke, W., 1982. Ravensburg. 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. High concentrations of lime prevent retting (Linke, 1982, p.20; Fasse, 1989, p.25; Birkigt-Quentin, Busse and Schäfer, 1995, p.9). Birkigt-Quentin, B., Busse, G. and Schäfer, W., 1995. (b) Spinning is a process of making fibres. If done correctly, the fibres can be extracted easily from the core. ting. Retting time must be carefully judged; under-retting makes separation difficult, and over-retting weakens the fibre. In the middle of a longish board, there is a round block with tightly fitted pointed nails. 0% average accuracy. The water tends to smell very bad and is poisonous to most of crops, humans and animals (Dambroth and Seehuber, 1988, p.83; Harzheim, 1989, p.20). Darren im Gebiet zwischen Neckar und Main. Almost 85% of the world's jute cultivation is concentrated in the Ganges Delta.. Hemp and nettle can be used to make linen like cloth and the steps for flax and hemp processing do not differ much. 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. Vom Flachs zum Leinengarn. Water retting is not as weather dependent, but for both harvests high temperatures shorten the retting time. Facebook Group: AOAM, Instagram | Twitter | YouTube Überlegungen zu einer Ofenform. Terminologie der Hanf- und Flachskultur in den frankoprovenzialischen Mundarten. Properties Jute is a long, soft, shiny vegetable fibre that can be spun into coarse, strong threads. Better results are obtained by scutching the flax beforehand. Flax in Flanders throughout the centuries. No retting required. So far I have only worked on small amounts of hemp, but the process works well even though it takes longer. The content is published under Creative Commons Attribution Non-Commercial 4.0 License. The retted fibres, being aggregates of elongated cells are still 9. Retting is the first extraction process to obtain high-quality fibres. 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. Die wirtschaftliche Bedeutung der Flachspflanze.
