A process for producing polyester multifilament yarns having excellent adhesion to rubbers or polyvinyl chloride

摘要

The present invention relates to industrial polyester fibers and preparation method thereof excellent in adhesion to the high strength and low rubber or poly while having the characteristic of contraction vinyl chloride (PVC).; The method of the present invention melt given radiation emulsion at a spinning fibers, have the properties of high strength and low shrinkage melt-stretching-subjected to the process of heat setting and relaxation during the continuous process of the wound, and then, with the rubber or polyvinyl chloride an epoxy compound containing functional emulsion immediately prior to winding so that the adhesive force is improved, based on the weight of the fiber, characterized in that the treatment with 0.4 to 1.0% by weight.; Prepared by the method of the present invention, high strength and low shrinkage polyester fiber strength of 7.4g / d to about 8.0g / d, and the elongation at break is 20% to 23%, dry heat shrinkage ratio [190 ℃, 0.01 during 15 minutes, early summer g / d, the test light when used (Testrite) as measured hereinafter] is not more than 3.5% by using, as a reinforcing material of rubber or polyvinyl chloride, which can reduce the deformation due to the contraction of the heat treatment of yarn, rubber or polyvinyl because of the chlorides and the high adhesive strength, when used as a reinforcing material, the method can exhibit a high dimensional stability an improvement in the durability and reliability of products using the same can enhance the added value of the products.
