Abstract
Production process of a highly shrinkable polyester yarn characterized in that it starts from a polyester obtained by reacting at least one compound chosen from terephthalic acid, its lower alcohol esters and its ethylene glycol esters (A), at least one other compound of terephthalic acid (B) represented by the formula: **(See formula)** (where R and R'are chosen from the hydrogen atom the lower alcohol radicals and the omega-hydroxyalkoyl lower groups, X is a hydrocarbon radical with at least one aromatic nucleus, Y is chosen from hydrogen the atoms of halogens and lower alcohol radicals and n is zero or a positive integer), and ethylene glycol (C) under conditions such that a polyester can be produced by reacting compounds (A) and (B) at a rate of at least 95 mole% (A) by at most 5 mol% of (B) with respect to the total of both calculated as 100 mol% by melt spinning the resulting linear copolyester and then stretching the resulting filament to a degree of 2.5 to 5.5 a a temperature of 60 to 100ºC.
