Abstract

The invention relates to a preparation method of high-visibility polyester monofilaments. The preparation method comprises the following steps: firstly, preparing a high-visibility powder material; secondly, preparing a high-visibility slice; thirdly, preparing the high-visibility polyester monofilaments: by using a rare earth light-storage slice as a core layer and using a conventional polyester slice as a skin layer, performing melt spinning by adopting a double-group composite spinning technology; cooling the slices by circular blowing air, oiling, first time drafting, winding and forming to obtain fibrils of the high-visibility polyester monofilaments, and carrying out second time drafting on the fibrils to obtain the high-visibility polyester monofilaments, wherein the cooling temperature of the circular air blowing is 25 to 28DEG C; the temperature of the first time drafting is 160 to 180DEG C, and draft multiple is 1.8 to 2.0 times; the winding speed is 1500 to 2000m / min; the temperature of the second time drafting is 135 to 145DEG C, and draft multiple is 3.0 to 3.5 times. The high-visibility polyester monofilaments prepared by the preparation method disclosed by the invention have a good luminous effect.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a preparation method of high-visibility polyester monofilament. Background technique [0002] Due to its excellent mechanical properties, sample diversity and low cost advantages, polyester monofilament currently accounts for 70% of the mesh application, and is the most important raw material for shoes, clothing and industrial mesh; but Today, the most important problem with the development of polyester monofilament is that there is less product diversification, which leads to less preparation and application of mesh materials in the later stage. Therefore, the development of diversified and differentiated polyester monofilament products is to meet the current rapid development. The optimal and urgent problem in the mesh industry; luminous and light-storing polyester fibers have been developed in the field of clothing. Poor compatibility with polyester matrix, and poo...
