Abstract: The invention provides a method of treating fabrics containing polyetherester fibers so that the fabrics retain their basis weight, power, and stretch without edge curl. Fabrics containing polyetherester fibers are heat-set after dyeing, preferably in a temperature range of 160-180° C. (dry) or 115-140° C. (steam).

Abstract: Textiles are first manufactured to attain dimensional stability and durability and thereby withstand the rigors of industrial rental and commercial laundering. Then, the garments are dyed in a two-stage process to yield outstanding colorfastness, pilling resistance, dimensional stability and durability. Garments are yielded that, even after extensive use, may be overdyed to custom colors in custom-sized batches to extend the useful life of stained or otherwise discolored garments. By performing the dyeing and/or overdyeing portions of the process at a location near the end user of the textile, transaction costs related to transportation of goods are minimized, technical resources are efficiently utilized, and large inventories of dyed garments need not be maintained, thereby reducing inventory expenses.

Abstract: Fine metallic particles-containing fibers with various fine metallic particles therein, which have fiber properties to such degree that they can be processed and worked, and which can exhibit various functions of the fine metallic particles, such as antibacterial deodorizing and electroconductive properties are provided, as well as a method for producing the same.

Abstract: Three reuasable surgical/medical fabrics provide improved barrier properties, as reflected by their Suter ratings, and also posses a "hand" similar to a "cotton hand". The Suter ratings are degraded in the order of 10%-20% after 100 sterile reprocessing cycles. The fabrics are reliable free of "voids", permitting their use as a single layer barrier panel. The fabrics are woven, respectively, with false twist 100/100 warp yarns and air texturized core and effect 2/60/100 fill yarns; flat trilobal 100/50 warp yarns and air texturized core and effect 2/60/100 fill yarns; and false twist 2/50/34 warp yarns and false twist 150/200 fill yarns. The fabrics are characterized by a minimum porosity of at least 10.times.10.sup.6 pores/square centimeter and maximum average. and mean pore sizes. The fabrics have a thickness of at least 0.005 inch, a weight of at least 3.5 ounces per square yard and a filament density of at least 2.0.times.10.sup.6 filaments per square inch.

Abstract: An elastic warp knitted fabric having a pulling out force for pulling out an elastic yarn from the knitted fabric of 30 g or more, and in which a shape of a sinker loop of a nonelastic yarn is maintained as a bulge shape after an application of a dyeing and finishing treatment. This elastic warp knitted fabric can be manufactured by using a specially prepared dyeing and finishing treatment, so that the sinker loop of the nonelastic yarn can be maintained in the treatment.

Abstract: Poly(p-phenylene terephthalamide) (PPD-T) fibers which have been dried are dyed with cationic dyes, or with disperse or acid dyes, by heating the fibers under a high pressure from 29 to 108 psi and at a temperature from 130.degree. to 180.degree. C.

Abstract: A simulated cashmere fabric comprises a warp knit ground comprising a stretch yarn such as an elastomeric yarn such as Lycra (RTM) and a raised and cropped face. The face yarn may be knitted in over a plurality of, say five, needles, and the fabric may be dyed before the raising and cropping steps and crushed and steamed after.

Abstract: A process for the preparation of a woven fabric of low air permeability which comprises preparing a woven fabric by use of a composite fiber of a splitting and severing type, which consists of polyester and polyamide and produces extremely fine fibers of 0.001 to 0.8 denier size, as a warp and/or a weft; treating thus obtained woven fabric by use of an aqueous emulsion of a swelling agent for polyester and nylon under the conditions where nylon is mainly allowed to swell and then shrink; scouring and dyeing the woven fabric; and after calendering the woven fabric with the use of heated rollers rotated under pressure.

Abstract: A method is disclosed of pretreating a plurality of high temperature heat set yarn bundles, e.g. polyester, that have different heat histories but are otherwise identical, to enable said yarns to be dyed uniformly. The method comprises measuring the pre-melt crystallization temperature of each polyester yarn bundle and thereafter heat treating each yarn bundle at a uniform temperature that is at least the same as or higher than the highest measured pre-melt crystallization temperature. Also disclosed are a method of uniformly dyeing polyester yarn bundles that are treated in a plurality of high temperature heat setting units and a method of determining the evenness of the internal temperature of high temperature heat setting apparatus.

Abstract: Electrically conducting fibers are prepared by introducing cyanic groups into a synthetic or natural starting fiber and then subjecting the fiber to a heat treatment with a copper compound, a reducing agent capable of reducing bivalent copper ions to monovalent copper ions, and a sulfur-containing compound capable of discharging a sulfur atom or sulfur ion for reaction with monovalent copper ions adsorbed by the fiber so that copper sulfide is impregnated into the fibers. Heat treatment with the sulfur-containing compound can be simultaneous with or separate from heat treatment with the copper compound and reducing agent. The electrically conducting fibers of the present invention have excellent conductivity, improved washability and are not plagued by the problem of static charging associated with the starting synthetic or natural fiber.
