Abstract: Disclosed herein is the preparation of woven fabrics suitable for use in manufacturing vehicle airbags. Such fabrics are woven from a plurality of polymeric, e.g., polyamide, warp and weft tapes which have preferably been slitted, preferably in the machine direction, from a thermoplastic polymer film, and preferably from such a film which has been drawn at least in the machine direction. The resulting fabrics exhibit both the relatively low basis weight, stiffness and small packing volume typical of nylon films, and the relatively high tear strength and high damage tolerance of yarn-based woven airbag fabrics.

Abstract: A method of making a polyamide copolymer includes subjecting a reaction mixture to conditions sufficient to form the polyamide copolymer, the reaction mixture including adduct A and adduct B. Adduct A is a 1:1 adduct of a diamine having the structure H2N-R1-NH2, or a salt thereof, and an aliphatic diacid having the structure HO—C(O)—R2-C(O)—OH, or a salt thereof. Adduct B is a 1:1 adduct of the diamine having the structure H2N-R1-NH2, or a salt thereof, and an aromatic diacid having the structure HO—C(O)—R3-C(O)—OH, or a salt thereof. At each occurrence, R1 and R2 can be independently a substituted or unsubstituted (C1-C20)alkylene. At each occurrence, R3 can be independently a substituted or unsubstituted (C6-C20)arylene. The molar ratio of adduct A to adduct B in the reaction mixture can be about 61:39 to about 90:10.

Abstract: Disclosed are processes for application of dyes and topical chemistries to single yarns during a yarn rewind process. The process foregoes the need for downstream environmentally unfavorable dyeing and low PH chemical treatment processes on the finished carpet. Further, neutral pH dye solutions can be used instead of the prior art low pH dye solutions. The single, treated yarn can then be twisted, weaved and tufted, twisted yarn under dry conditions, and the twisted yarn subsequently weaved or weaved and tufted, into a finished fabric or carpet. Also disclosed are systems, BCF yarns, and carpets made from the BCF yarn treated by the disclosed processes.
