Abstract:
PROBLEM TO BE SOLVED: To provide a water-repellent reversibly air-permeable woven or knitted fabric having both of an air-permeable properties reversibly changing the air-permeability so as to rapidly correspond to the moisture change in the interior of clothes, and the water repellency preventing the invasion of water from the outside of the clothes. SOLUTION: The water-repellent reversibly air-permeable woven or knitted fabric contains ≥30 wt.% swellable conjugate fiber obtained by conjugating a high-swelling component and a low-swelling component so as to form a side-by-side shape, and has a water repellent imparted thereto. The water repellency of the woven or knitted fabric is grade 3 or more, and the variation of of the air permeability of the woven or knitted fabric, represented by the equation: (variation of air permeability (%))=[{(air permeability (B) in wet state)-(initial air permeability (A))}/(initial air permeability (A))]×100 is ≥10%. The woven or knitted fabric is obtained by subjecting the woven or knitted fabric including the conjugate fiber obtained by conjugating the high-swelling component and the low-swelling component so as to form the side-by-side shape to water-repelling finishing, and subjecting the resultant product to rubbing finishing.

Abstract:
It is disclosed a method of producing a yarn having the look and feel of natural fibers, the method comprising the steps of preparing a first plurality of man-made textile fibers or a second plurality of natural textile fibers, the first and second plurality of textile fibers being obtained from breaking the first or the second textile fibers under the effect of a mechanical force applied to the first or the second textile fibers. A final blend for producing the yarn, can be prepared by adding the first plurality of textile fibers to a plurality of man-made fibers, or by adding the second plurality of textile fibers to a plurality of man-made fibers, or by adding the first plurality of textile fibers to the second plurality of textile fibers.
Abstract:
Densified textile aggregates are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of densified textile derived syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The densified textile derived syngas quality, composition, and throughput are suitable for produce a wide range of chemicals and polymers, including methanol, acetic acid, methyl acetate, acetic anhydride, and cellulose esters through a variety of reaction schemes in which at least a portion of the chemical or polymer originates with densified textile derived syngas.
Abstract:
A fiber blend containing: (a) a cellulose acetate (CA) staple fibers having a denier per filament (DPF) of 3.0 or less; and (b) structural staple fibers having a dpf of 6.0 or more; and (c) optionally binder fibers. The fiber blend can be made into nonwoven webs for heat-bonding and subsequent use as thermal insulation in, e.g., outerwear, bedding, etc. The fiber blend can now contain sustainably derived fibers, optionally biodegradable, that provide good thermal insulation clo values and loft even after multiple wash cycles along with good short term compression recovery.
Abstract:
Textiles are provided that include fibrous cellulosic materials having an α-cellulose content of less than about 93%, the fibrous materials being spun, woven, knitted, or entangled. The fibrous cellulosic materials can be irradiated with a dose of ionizing radiation that is sufficient to increase the molecular weight of the cellulosic materials without causing significant depolymerization of the cellulosic materials. Methods of treating textiles that include irradiating the textiles are also provided.
Abstract:
Flame resistant fabrics are formed by warp and fill yarns having different fiber contents. The fabrics are constructed, for example, by selection of a suitable weaving pattern, such that the body side of the fabric and the face side of the fabric have different properties. The fabrics described herein can be printable and dyeable on both sides of the fabric and are suitable for use in military and industrial garments. Methods of forming flame resistant fabrics, and methods for forming garments from the fabrics, are also described.
Abstract:
The present invention provides a nanofiber manufacturing method and a nanofiber manufacturing device. A solution 25 in which a polymer is dissolved in a solvent is supplied from a distal end of a nozzle 16 to form a Taylor cone 44 at a distal end opening 16b. By applying a voltage between the solution 25 and a collector 50 using a power supply portion 62, an electrospinning jet 45 is sprayed from the Taylor cone 44 to the collector 50. At the start or stop of electrospinning, a blocking member 48 is inserted into a spraying area 42 of the electrospinning jet 45 such that an unstable electrospinning jet or unstable nanofibers are received. A product is not manufactured from an unstable electrospinning jet formed at the start or stop of electrospinning, and the manufacturing of a defective product is prevented.
Abstract:
The invention relates to a method for dissolving the components of gel forming materials suitable for use in wound care comprising the steps of admixing said components with an ionic liquid. The ionic liquid may be selected from the group of tertiary amine N-oxides, N,N-dimethyl formamide/nitrogen tetroxide mixtures, dimethyl sulphoxide/paraformaldehyde mixtures and solutions of limium chloride in N,N-dimethyl acetamide or N-methyl pyrrolidone.
