    Growing flax. Flax seed is sewn densely in the field, so that the plants grow quite closely together. This insures the plants grow straight, with little branching, producing long, straight fibers in the stems. Flax requi res a soil that is broken up as finely as can be managed, as it is sown shallowly, and does not root deeply. Flax grows best The action which takes places during the retting of hemp is similar to that which takes place with other fibres, such as flax, jute, Hibiscus cannabinus, etc. Three different methods are used, namely water retting, dew retting, and snow retting-according to the climatic

    This invention describes a method for retting and cottonizing bast fiber raw materials in which fungus Fusarium sambucinum is used. By using the retting method of this invention the fiber production line can be rendered more efficient, but most of all it can be used to affect the structural and visual characteristics of the fiber ://   Hemp goes through a similar process to linen, called retting, using water to break down or rot the cellular tissues of the stem allowing the bundles of bast-fibers to separate from the stem of the plant. This usually happens right after harvesting the hemp in fields where the hemp is left to ret in the fields before making the trip to ://

    Processing lines, however, such as the Unified Line of Czech Flax Machinery or Lin Line of Temafa, produce a “total fiber” from flax stems, without traditional long line and tow products. Flax fibers may be “cottonized,” that is, refined and shortened for use in short stable spinning or The present document is a companion document to Dir It is intended to provide background information on the biology of Linum usitatissimum L., its centres of origin, its related species, and the potential for gene introgression from L. usitatissimum into

Fibers are obtained from flax stems by the process of retting. Two methods employed for retting flax at commercial levels using pectinolytic microorganisms are water- and :// Water Retting Water retting submerges the flax straw into some sort of container or body of water.

It depends on the action of bacteria, rather than mold, to eliminate the unwanted pieces of stem. The method is generally regarded as requiring more work, but producing a blonder fiber than gray fiber produced by dew ://   Harvesting, Retting, and Fiber Separation Harvesting and fiber processing differ depending on whether the crop is grown for high-quality textile fiber, for seed, or for fiber and seed.

The Oregon study, Feasibility of Industrial Hemp Production in the United States Pacific Northwest, summarizes current information and research on hemp Image from Linum usitatissimum, commonly known as flax, is an exceptionally good source of fibre (or fiber in the US).

The seed, often called flaxseed or linseed, contains a great deal of dietary fibre, and is very popular for animal feed and human health nuts. The seeds also make a popular egg substitute in vegan baking.

What a lot of people don't seem to realize is that flax 2 days ago  Retting is simply rotting as a result of dew, rain and bacterial action. Machines were developed to separate the fibers mechanically after retting was complete, but the cost was high, the loss of fiber great, and the quality of fiber comparatively low.

With the new machine, known as a decorticator, hemp is cut with a slightly modified grain :// Notably, in some cases the treatment of raw product and mechanization of systems have changed radically since the s. With the introduction of modern machinery and equipment in processing facilities the field of occupational hygiene has largely neglected worker exposure to hemp dust in recent decades (Davidson et al., a, b).

Flax fibre properties are controlled by the molecular fine structure, which is affected by the plant growing conditions and the retting procedure that is applied. The process of retting tends to separate the bundles of flax fibres into individual fibres, although many fibres remaining together in bundles [Hearle ].

The dew retting process takes approx. weeks to finish based on weather conditions. In water retting, the stalks are soaked for approx.

20 days to loosen the fiber. This method produces a higher quality fiber but is costly and if the water is not disposed of properly can pollute the body of water used in the   the bast fiber that bypass traditional retting and scutch-ing.

What’s more, hemp fabric is stronger, more long-lasting, and more beneficial to the environment because the process of producing hemp fabric has less. The possibility to obtain long aligned fiber bundles from hemp is limited by the lack of dedicated harvesting machines that can mow hemp stems, lay them on the field in aligned swaths and cut them in 1 m long portions, so that they can be fed in flax scutching lines (Amaducci, ; Venturi et al., ; Amaducci and Gusovious, ).Further bottlenecks, that hamper the production of long hemp   Improved+chemical+retting+of+kenaf+fibers - 利用保水剂提高土壤的保水性 百度首页 登录 加入VIP 享VIP专享文档下载特权 赠共享文档下载特权 w优质文档免费下载 赠百度阅读VIP精品版 立即开   deal more remains to be accomplished in bringing together the farmer and capitalist in the practical work of growing, retting, scutching, and preparing for market American flax fiber, for questions of culture are settled.
