Abstract: PURPOSE:To obtain the subject artificial suede structure, not impairing handle and quality and having softness and excellent flame retardance by applying a specific flame retardant to an artificial suede structure. CONSTITUTION:The objective artificial suede structure having softness and excellent flame retardance is obtained by applying one kind of flame retardant selected from a compound of formula I (R and R are 2-3C aliphatic hydrocarbon residue; m is 1 or 2; n is 1-30) and a compound of formula II (R and R are 2-3C aliphatic hydrocarbon residue; m is 1 or 2; a is 1-3), e.g. triphenylphosphate, tetrabromobisphenol A, tetrabromobisphenol A ethylene oxide adduct or tetrabromobisphenol S to the rear face of an artificial suede structure consisting a thermoplastic synthetic fiber, in which a polyurethane is impregnated, in an amount of 5-50wt.%. Furthermore, coating of this flame retardant is preferably carried out after previously lining fabric such as woven or knit fabric or nonwoven fabric and then applying the flame retardant to the fabric.

Abstract: PURPOSE:To suppress bleed stain of dye by coating a synthetic fiber sheet dyed with a disperse dye with a resin, heat-treating, then subjecting to reductive cleaning, coating the sheet with a porous particle-containing resin and setting the sheet at a temperature lower than the heat treatment temperature. CONSTITUTION:A synthetic fiber sheet made of a polyamide is dyed with a disperse dye, coated with a resin such as acrylic resin, heat-treated, with a resin, then subjected to acidic reductive cleaning, further coated with a resin containing silica particles having =300m /g average particle diameter and set for finishing at a temperature lower than the above-mentioned heat treatment temperature so that coating processing of synthetic fiber sheet hardly causing bleed stain of dye is made possible. An azo-dye is preferable as the disperse dye.

Abstract: PURPOSE:To provide the subject web having excellent moisture-permeability and water pressure resistance by forming on the web a resin coating film comprising a mixture of an urethane prepolymer having isocyanate ends, a specific amino acid anhydride and an amine. CONSTITUTION:An urethane prepolymer having isocyanate ends is reacted with a N-carboxy amino acid anhydride and with an amine (e.g. hydrazine or ethylene diamine). The reaction product is mixed with a polyurethane resin having a 100% modulus of >=40kg/cm in a wt. ratio of 20-80:90-10 and further with an isocyanate crosslinking agent. The mixture is dissolved in dimethyl- formamide, etc., coated on a web and coagulated to form a resin coating film for providing a moisture-permeable and waterproof web having a moisture permeability of >=8000g/m .24hr and a water pressure resistance of >=2000mm H2O. The web is comfortable without causing stuffiness stickiness or water leakage.
