摘要:
A method for producing charge-modified polyester comprising treating the polyester with at least one agent sufficient to cause hydrolysis of the polyester and a charge-modifier having one or more epoxy groups with a fixed formal charge, resulting in the formation of a bond between the one or more epoxy groups and the polyester. The polyester may be treated with the agent, which is presently preferred to be an alkaline, amine, or combination of both, and charge-modifier, which could have a positive or negative charge.

Disclosed is a method to provide rayon-containing fabrics with the same sense of touch as that of bast fiber fabrics. Rayon-containing fabrics are mercerized in a solution of caustic soda which is controlled in concentration and temperature. The method allows the mass production of the fabrics that feel like bast fiber fabrics.

The present invention provides a method of treating wool, wool fibers or animal hair an alkali-containing alcohol solution, followed by a proteolytic enzyme in aqueous solution. The described method results in improved shrink-resistance, and may result in improvements in handle, appearance, wettability, reduction of felting tendency, increased whiteness, reduction of pilling, improved softness, improved tensile strength, and improved dyeing characteristics such as dye uptake and dye washfastness.
摘要:
A process for the treatment of warp knitted fabrics, by which warp knitted fabrics containing regenerated cellulose fibers can be suppressed in barry mark formation or get rid of the mark; and warp knitted fabrics treated by the process. The process comprises crumpling a warp knitted fabric containing regenerated cellulose fibers and subjecting the resulting fabric to alkaline treatment in a spread state.

The fibrillation tendency of lyocell fibres can be reduced by reaction in never-dried state at elevated temperature with a solution of a chemical reagent bearing a plurality of acrylamido groups, the average number of acrylamido groups per molecule of the chemical reagent in the solution being at least 2.1. The amount of the chemical reagent which reacts with the fibre may be as low as 0.25 to 1 percent by weight based on the weight of air dry-fibre. The dye affinity of lyocell fibres can be increased by reaction in never-dried state with a solution of a chemical reagent bearing a plurality of acrylamido groups under conditions such that 1 to 3 percent of the chemical reagent by weight based on the weight of air-dry fibre becomes fixed to the fibre.

Disclosed are strength loss resistant methods for treating cotton toweling with cellulase so as to impart permanent softening to the toweling. In particular, the methods disclosed herein involve the application of a specified amount of cellulase onto one or both of the surfaces of a cotton toweling so as to result in permanent softening of the toweling.
摘要:
Water-dispersible polyester fiber and precursor filament tow whose surface is modified and water-dispersibility is improved by treatment of undrawn polyester filaments with a very small amount of caustic, when freshly-extruded, preferably in a spin-finish.
摘要:
The object of the present invention is a product, which contains cellulose and can be a fibre or textile structure with large porosity and swelling capacity.
摘要:
A leather-touch pile fabric in an identifiable double layer structure consisting of an upright hair-like raised fiber layer and down-like raised fiber layer which is used as artificial leather. The method of this invention provides a pile fabric knitted of pile yarns composed of a mixture of polyester fibers in finite length sharpened at tips to be used as upright hair-like fibers and other polyester fibers in finite length to be used as down-like fibers more likely to be eroded by alkali treatment than said polyester fibers that compose said upright hair-like fibers, in which, after adding alkaline treating agent (6) having a specific viscosity to the surface of a raised fiber layer of said knitted pile fabric, heat-treatment is applied to said fabric so as to shorten the length and sharpen the tip of each down-like fiber, whereby a pile fabric (1) having upright hair-like raised fibers (2) sharpened at tips and down-like raised fibers (3) sufficiently uniform in length is obtained.
