Abstract

The invention relates to a bi-component composite monofilament and a preparation method thereof. The composite monofilament is composed of a skin layer and a core layer, and is characterized in that the core layer is coated with the skin layer, the skin layer is made of a modified low-melting-point polyester material, the core layer is made of a low-melting-point PET material, the melting point temperature of the skin layer is lower than that of the core layer, and the mass ratio of polyester of the skin layer to polyester of the core layer is (20-50): (50-80). By the adoption of the scheme, the bi-component composite monofilament is good in extensibility, good in flexibility, resistant to folding, low in hot melting bonding shrinkage rate, good in high-temperature compression molding after being blended with a polyester yarn fabric, smooth to iron and good in mechanical resistance.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a two-component composite monofilament and a preparation method thereof. Background technique [0002] At present, in order to achieve product stability in the field of shoe materials in the market, there will be heating fuses to fix the support during the weaving process. The new yarn of the present invention can be used to replace the thermal fuses, and weaving a little yarn can play the same role in fixing the yarn. And the role of supporting yarn, has a wide range of application prospects. [0003] The prior art mainly has the following disadvantages: the extensibility of the existing monofilament is not good, the hot-melt adhesive shrinkage rate is low, and the breaking strength and elongation index of the thread are unstable. Contents of the invention [0004] In order to solve the defects of the aforementioned monofilament, the present invention provides a two-componen...
