Abstract: A processing line of bast fiber is provided. The processing line is comprised of various devices for carding, cutting, degumming, high temperature washing, separating and water washing, softening, drying, batching and applying oil, permeating and reconditioning, stretching-breaking carding, and combing and sorting. The processing line of bast fiber can improve production efficiency, and improve the yield of long hemp fibers. Moreover, the produced fiber has stable quality and is convenient for post-processing.

Abstract: A method of splitting hollow cellulosic fibers employs the steps of wetting the fibers, feeding the wet fibers to a gaseous flow, and conducting the gaseous flow carrying the fibers through a venturi tube, the pressure drop in the venturi tube throat bringing a pressure difference between liquid inside the fibers and gas outside of the fibers and causing the fibers to split in their longitudinal direction, to open the lumen inside the fibers.

Abstract: A method for processing bast-fiber materials involving loosening a material, placing said material in an aqueous medium, hydrodynamically processing material successively in two modes: first, in a continuous mode by performing a hydrodynamic wave field action, and then in a pulsed mode by performing a shock-wave action, wherein the pressure amplitude of the positive wave phase in the continuous mode is less than the pressure amplitude of the positive wave phase in the pulsed mode, and removing the material from the aqueous medium. It is possible by the method to produce a high quality cottonine, the linear density of which is equal to or less than 0.3 Tex with the optimal energy consumption of the production process.

Abstract: Taught is a cotton stalk bark fiber. The fiber is a natural textile fiber made of cotton stalk balk. The length of the fiber is 5 mm-65 mm. The fineness thereof is 0.3-2.5 denier. The intensity thereof is 0.284-0.432 N/tex. The breaking elongation rate thereof is 3%-6%. Taught is further a method for processing cotton stalk bark fiber comprising peeling, skimming, degumming, preserving, cutting, tanning, opening, carding, baking, boxing and classifying, and packaging. The invention provides an inexpensive natural fiber having wide applications in the textile industry. The fiber has a similar performance to bast fiber, higher intensity than cotton fiber, and may be blended with other natural fiber, man-made fibers and recycled fiber to form fiber yarn for various purposes. This method changes waste into a commodity, and brings about economic and social benefits.

Abstract: The method of treating the flax fiber consists of cleaning, cottonisation, retting and drying of the raw material, which could be short flax fiber No 2, combing wastes and other wastes. The opening of the flax fiber is carried out 3 times: first before the cleaning, second before the retting, and third after drying, which is done after cottonisation. This is carried out by electro-hydraulic treatment to a processed material placed in a liquid. This invention allows for quality improvement of the flax fibers and simplification of the processing.

Abstract: A process for sclerenchyma fibers, in particular flax, includes mechanical treatment accompanied by formation of a fiber strip and alignment of the fibers essentially parallel to one another. The fibers of the fiber strip are freed of wood constituents, greases, pectins and other impurities by a chemical and/or cooking treatment of the fiber strip. The treated fiber strip is dried and then divided into shorter sections. These sections are at least partly pulled apart or opened to form fiber bundles. The fiber bundles are carded at a set moisture content of at least 10%-wt. and combined to give a fine fiber strip.

Abstract: The extraction of fibres from corn husks and/or leaves or corn husks alone is accomplished to provide fibres which are substantially free of the vegetable binder material. The corn husks (and leaves) are preferably allowed to dry to a substantially moisture-free state and are then soaked in a caustic solution for a predetermined period in which the caustic solution frees the fibres from the vegetable matter of the corn husks (and leaves) and reacts with the fibre to strengthen the same. Before the caustic material has an opportunity to degrade the fibres of the corn husks (and leaves), the caustic solution is diluted by rinsing the corn husks (and leaves). While still wet, the fibrous material is straightened so as to dispose the fibrous components of the corn husks (and leaves) in substantially parallel arrangement and in the process the excess binder material is separated from the fibrous material.

Abstract: Luffas are subject to disintegration into fibers which are carded and needled to a textile support. The resulting product is impregnated with a synthetic resin, dried and calendared to produce a foil from which, for example, inner soles can be cut or stamped.

Abstract: The debris and pith removal from bagasse fiber is significantly enhanced by the flow of fiber from one depithing zone into a fiber washing zone and then to a second depithing zone without any intermediate settling of piling of the fiber. The fiber is maintained in a separated condition throughout the first depithing zone, the washer and the subsequent depithing zone. The result is a bagasse fiber having a greater quantity of the debris and pith removed with much less fiber damage.

Abstract: The pith removal from bagasse fiber is significantly enhanced by the flow of fiber directly from one depithing zone to a second depithing zone without any intermediate settling or pilings of the fiber. The fiber is maintained in a separated condition during the flow from one depithing zone to another depithing zone. The result is a bagasse fiber having a greater quantity of the pith removed with less fiber damage. It is also advantageous to provide a number of conveyors to transport fibrous material to a dual zone depithers and for the removal of depithed fiber and pitch from these depithers. This reduces fiber handling before, during and after depithing.
