Polyether-ester fibres for multiple dyed carpets - made from terephthalic acid, cyclohexane-di:methanol and polyoxyethylene-glycol and contg. manganese, phosphorus, stabiliser and titanium

摘要

Polyetherester-based textile fibre consist of (A) a polyetherester of terephthalic acid and a diol component of (a) 1,4-cyclohexane-dimethanol and (b) 3-12 wt.% wrt polyetherester wt. of a poly(oxyethylene)-glycol having mol. wt. 300-800; and also, w.r.t. polyetherester wt., (B) 0-150 ppm Mn ions; (C) 20-500 ppm P; (D) 1000-5000 ppm stabiliser to reduce oxidative degradation of polyetherester and (E) 25-200 ppm Ti, derived from a soluble organic, tetravalent Ti cpd. Fibres can be used for prodn. of multi-coloured, e.g. 3-coloured carpets. They are suitable for multiple dyeing without using a carrier. Fibres have high strength, e.g. tear-strength, elongation, modulus and recovery; fastness to light and gas; can be dyed quickly; and have good textile processing and yarn spinning properties.
