Abstract

The invention relates to an activated high-modulus low-shrinkage polyester industrial yarn and a preparation method of the same. The activated high-modulus low-shrinkage polyester industrial yarn is formed in a way that high-adhesion PET (polyester) slices are taken as raw materials and then are subjected to melt spinning, a proper amount of spinning oil is added, the drawing formation is carried out, a proper quantity of activators are added and then the winding is carried out. A formula contains the following components by weight parts: 100 parts of Halead (HLD) 301 high-adhesion PET, 0.2-0.6 part of Sanyo 911 spinning oil and 0.2-0.5 part of a Syma TC12 activator. The preparation method comprises the steps of: solid-phase polymerizing, melting, metering, cooling forming, oiling, drawing, activator feeding and winding. According to the yarn, the product breaking strength is over 7.0CN/dtex, the yarn has the advantages of good abrasion resistance, small index of dimensional stability, uniform content of the activator, and the like, and can be applied to the field of tyre cord fabrics, and the manufacturing cost of post processing is saved remarkably.

Description

technical field [0001] The invention belongs to the technical field of polymer fiber production, and in particular relates to an activated high-modulus low-shrinkage polyester industrial yarn and a preparation method thereof. Background technique [0002] In recent years, with the continuous advancement of technology, high-modulus low-shrinkage polyester industrial yarns have continued to expand in the fields of tire cord fabrics, rubber skeleton materials, etc., and the market demand for high-modulus low-shrinkage polyester industrial yarns is increasing. The high-modulus low-shrinkage polyester industrial filaments currently on the market can only be post-processed on the dipping equipment of the two-bath method because they have not been pre-activated. At present, the mainstream dipping equipment in developed countries such as Europe and the United States mainly adopts one-bath dipping equipment, and ordinary high-modulus low-polyester industrial yarn cannot be processed ...
