Abstract
A textile fastener consists of monofilaments (12, 14; 22, 28) made of polyesters which have been formed from dicarboxylic acid and diol components and into which a flame retardant has been incorporated. The flame retardant is present in the polyester chains as copolymerized elements having the structural units of the general formula ##STR1## where R is alkylene, arylene or aralkylene and R.sub.1 is alkyl, aryl or aralkyl.
Claims3
A textile fastener made of fibers formed from flame-resistant synthetic fiber material, wherein said fiber material comprises monofilaments having a round cross-section and a diameter in the range of from 0.15 to 0.25 mm and 0.45 to 1.20 mm and consisting of a polyester which has been formed from a dicarboxylic acid and a diol component and which contains copolymerized in its chain elements of the structural formula ##STR2## wherein R is saturated open-chain or cyclic alkylene, arylene or aralkylene and R1 is alkyl of 1 to 6 carbon atoms, aryl or aralkyl.
