WOOVEN FABRICS OF POLYESTER FOR AIRBAGS Russian patent published in 2013 - IPC D03D1/02 

FIELD: textiles, paper.

SUBSTANCE: invention relates to polyether wooven fabric, suitable for use in airbags. It has seams, woven from polyester filament tread with a specific tensile strength of 65 kN/tex or more and instantaneous temperature creep (ITC) at 100°C as defined herein, of 0.5% or less, wherein the polyester filament thread is formed of a polyester polymer which is selected from the group consisting of polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polybutylene naphthalate, polyethylene-1 ,2-bis(phenoxy) ethane 4,4'-dicarboxylate, poly (1,4-cyclohexylenedimethylene) terephthalate and copolymers comprising at least one type of recurring structural units of the aforementioned polymers, for example, copolymer polyesters, polyethylene terephthalate/polyethylene isophthalate, polyesters copolymer of polybutylene terephthalate/polybutylene naphthalate, polyesters, copolymer of polybutylene terephthalate/polybutylene decane dicarboxylate, and mixtures of two or more of the aforementioned polymers and copolymers, and wherein the amorphous badly oriented yarn is stretched at least five times in order to maximise strength prior to relaxation.

EFFECT: reducing of seams untwisting.
