Abstract
The invention relates to a method for endowing terylene with functional group by means of inlaying. The method comprises the following steps: making use of inlaying principles and providing appropriate conditions to generate gaps among molecular chain segments of terylene fiber; inlaying functional group, which contains hydroxyl, amido and the like and can carry out chemical reaction, between the molecular chain segments of the terylene fiber; a compound containing the functional group is firmly locked in the terylene fiber after external conditions are removed, thereby endowing the terylene with a great amount of functional groups and ensuring that the surface of terylene can be grafted with protein or undergoes other processing to prepare the terylene fiber with better performances. The method is simple and easy to carry out and does not influence the wearing performance of the terylene 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 substantially.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, allow the terylene surface produce more hydroxyl, thereby the research that albumen is connected on the polyster fibre is reported.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 substantially.
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.By 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 by felicity condition is provided, make between the molecule segment of polyster fibre and produce the space, the sense that allows 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 High Temperature High Pressure, 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, and is very firm.
The inventive method realizes by following steps:
It is 1.5～2% poly-vinyl alcohol solution that polyster fibre is put into mass percent concentration with 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 replace with the solution of reactive functionality compounds such as other hydroxyl, amino.
Said method is a high temperature and high pressure method, a kind of method of just inlaying, and the present invention also can inlay by carrier inlaying process, hot melt inlaying process.
Dacron after inlaying carries out grafting with milk protein and crosslinking agent, and is very firm, can be by wash-out.
Advantage of the present invention is: under High Temperature High Pressure, 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.
