Abstract
A method for endowing terylene with functional groups by an inlaying method utilizes an inlaying principle, generates gaps among molecular chain segments of terylene fibers by providing proper conditions, enables the functional groups containing hydroxyl, amino and the like capable of carrying out chemical reaction to be inlaid among the molecular chain segments of the terylene fibers, and after external conditions are removed, compounds containing the functional groups are firmly locked in the terylene fibers, endows a great amount of functional groups to the terylene, and enables the surface of the terylene to be grafted with protein and processed by other methods to prepare the terylene fibers with higher performance. The method is simple and easy to implement, and does not influence the wearability of the polyester fiber.
Description
Technical field
The present invention relates to the Textile Engineering technical field, particularly relate to the method for endowing terylene fiber, fabric functional group, thereby utilize the functional group of polyster fibre to carry out grafted protein, dyeing, change the processing characteristics of terylene, exploitation terylene new product.
Background technology
Terylene is the most outstanding fiber of wearability in the chemical fibre, more than the summation of its other all chemical fibres of amount ratio.Terylene has good stiffness, fold elasticity, wash and wear characteristic.The chemical raw material of terylene is the two hydroxyl second diester (PET) of poly terephthalic acid, except polymer ends the minute quantity hydroxyl outside, PET fiber surface does not have utilizable group basically.Therefore, terylene processing is developed new product and is restricted.At the good protein of chemical fibre surface grafting biocompatibility, exploitation had both had good wearability, had the high-performance fiber or the lining of good biocompatibility again, was that application potential and market prospects are arranged very much.But because the terylene surface does not have utilizable group basically, grafted protein generally all can only be used on acrylic fibers, polyvinyl alcohol fibre.Have terylene is carried out the alkali decrement, let the terylene surface produce more hydroxyl, thereby albumen is connected on the research report on the polyster fibre.But the alkali decrement can reduce wearability such as the stiffness, fold elasticity of dacron, and the hydroxyl that increases seldom, and the albumen of grafting is insecure, can come off, and therefore, does not have application prospect basically.
The new technology and the method for exploitation endowing terylene fiber surface functional group are not damaged the original performance of polyster fibre, improve the processing characteristics of polyster fibre, have very important application prospect and great economic worth.
Summary of the invention
The object of the present invention is to provide a kind of endowing terylene fiber functional group, improve the method for polyster fibre processing characteristics.Through the functional group of endowing terylene, terylene is carried out the grafted protein modification, prepare high performance terylene azelon etc., and in the modification of others.
Technical thought of the present invention is to utilize to inlay principle; Promptly through felicity condition is provided, make between the molecule segment of polyster fibre and produce the space, the sense that lets hydroxyl, amino etc. can carry out chemical reaction is embedded between the polyster fibre molecule segment; After removing external condition; Contain functional compounds and firmly be locked in the polyster fibre, thus endowing terylene fiber functional group, but endowing terylene graft reaction performance.
One of method is under HTHP, and the molecule segment of terylene moves, and produces the slit, and hydroxyl, amino etc. can carry out the sense of chemical reaction such as the polyvinyl alcohol of hydroxyl enters into the slit, thereby is embedded in the polyster fibre.After cooling, the molecule segment of terylene no longer moves, and the polyvinyl alcohol that is embedded in the PET fiber surface layer is locked in the terylene surface firmly, reaches the purpose of endowing terylene fiber functional group.Because the molecule segment of polyster fibre needs at high temperature just can move, and produces the slit, under cryogenic conditions, can not produce motion and slit.So in the ordinary course of things, the compound that is embedded in the terylene surface can not come off, very firmly.
The inventive method realizes through following steps:
It is 1.5～2% poly-vinyl alcohol solution that polyster fibre is put into the mass percent concentration that uses the hot water dissolving; Under 125～130 ℃ of conditions, polyster fibre is inlayed; bath raio: 1: 30～1: 40; inlay time 30～60min, the polyvinyl alcohol that contains great amount of hydroxy group is embedded on the terylene surface, thus endowing terylene with functional group.
But poly-vinyl alcohol solution also can use the solution of reactive functionality compounds such as other hydroxyl, amino to replace.
Said method is a high temperature and high pressure method, a kind of method of just inlaying, and the present invention also can inlay through carrier inlaying process, hot melt inlaying process.
Dacron after inlaying carries out grafting with milk protein and crosslinking agent, very firmly, and can be by wash-out.
Advantage of the present invention is: under HTHP, inlay hydroxy-containing compounds on the terylene surface, can a large amount of functional group of endowing terylene, and make the terylene surface can grafted protein, and other processing, prepare more high performance polyster fibre.Method is simple, do not influence the wearability of polyster fibre.
