Description
The present invention relates to the fiber that polyester, polyethers, polysiloxanes terpolymer make, particularly the fiber of polyester, polyethers, polysiloxanes ternary statistic copolymer.
Adopt polyethers in the prior art, ester is made the high elasticity flexible fibre, for example JP63-264965 adopts the block copolymer of polyester and polyethers to prepare the multiply fiber, and the disclosed highly elastic fiber of being formed with polyetherester block copolymer and phthalic acid second diester of JP63-227813, manufacture method and prescription thereof as for the JP61-289121 elastomer that then to disclose with 11 methylene diamine and ten dimethylene diamines and poly-alkoxyl ethylene glycol and poly-alkoxyl ethylenediamine be Main Ingredients and Appearance, the fiber that these methods make is to have improved elasticity and heat endurance mostly, but all exist the stock-dye difficulty, the shortcoming that fabric feeling difference and copolymerization rate are slow.
The purpose of this invention is to provide a kind of ternary statistic copolymer fiber and manufacture method thereof with polyester, polyethers and polysiloxanes, the dye uptake height of gained fiber, good heat stability, the good hand touch of fabric, and also its rate of polymerization is also fast when combined polymerization.
Well-known polyester (as polyethylene terephthalate) fiber has mechanical strength and modulus is higher, the advantage that ABRASION RESISTANCE and heat resistance are better, chemical resistance of concrete is strong, but the dyeing difficulty of its fiber.Polyethers is as the property-modifying additive of polyester, the ternary copolymer fibre of gained just can be dyeed with DISPERSE DYES under normal pressure, and the dye-uptake height, the COLOR FASTNESS height, hygroscopicity and antistatic behaviour wait premium properties well, but also exist poor heat stability, as when being processed into fiber, run into its color and luster of higher temperature and physical and mechanical properties variation, particularly its fabric is after 180-200 ℃ of following HEAT SETTING, the fabric feeling variation appears, defect such as its colour changed into yellow.
The main cause of this polyether ester fibre poor heat stability is because exist a large amount of ehter bonds in macromolecular chain, and the oxygen resistence of ehter bond is poor, under higher temperature, meet oxygen and can produce violent thermal oxidative degradation and thermal degradation, so generally be to adopt the method that adds heat stabilizer to suppress its thermal oxidative degradation and thermal degradation, but shortcoming of also having brought the polyether ester fusing point to descend.
The purpose of this invention is to provide a kind of change conventional practice, promptly adopt in polyethers, polyester and to add polysiloxanes and make the ternary statistic copolymer, the heat endurance that reduces the method for ether component amount simultaneously and a kind of because polysiloxanes is provided is more than the polyethers height, so the heat endurance of terpolymer that makes gained is than original polyether ester binary copolymerization object height, the dye-uptake height of fiber, the fiber that fabric feeling is good.
Another object of the present invention provides the method that a kind of ternary polymerization time is shortened greatly, its reason is because alcoholysis reaction aggravation in the course of reaction during traditional polyether ester binary copolymerization, copolycondensation speed descends, so polymerization time increases, and behind the adding polysiloxanes, because the end group reactivity is big, so combined polymerization speed is accelerated.
Now component of the present invention is described in down:
(1) contains the esterification products of a small amount of oligomer
Adopting the direct esterification method is that mol ratio with terephthalic acid (TPA) and ethylene glycol is 1: 1.1-1.3, esterification temperature is from 190 ℃-230 ℃, esterification pressure is the 1.5-2.5 kg/cm, about about 3 hours of esterification time, polycondensation catalyst is antimonous oxide (counting 0.025% with terephthalic acid (TPA) weight), and the esterification products of acetic acid (counting 0.008-0.024% with terephthalic acid (TPA) weight) gained is ethylene glycol terephthalate and the mixture (being designated hereinafter simply as esterification products) that contains a small amount of oligomer.
