Abstract

The invention discloses an easily degradable coated yarn and a preparation method thereof. The coated yarn comprises a core layer and a skin layer, wherein the core layer is made of a PLA composite material; and the material of the skin layer is a PBAT / PBS / PCL reactive blending material. According to the coated yarn, the PLA composite material serves as the core layer, the PBAT / PBS / PCL reactive blending material serves as the skin layer, the core layer and the skin layer are both made of easily-degradable environment-friendly materials, and the prepared coated yarn has good toughness, heat resistance and heat shrinkage resistance, good deformation resistance and outstanding heat insulation effect; and after being used, the degradable plastic can be completely degraded in a natural environment for a period of time, does not cause burden to the environment, and has good economic benefits and environmental protection benefits.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an easily degradable coated yarn and a preparation method thereof. Background technique [0002] With the advancement of synthetic fiber spinning technology and the improvement of people's consumption level, people put forward new requirements for the characteristics of synthetic fibers and their textiles. As a new high-quality synthetic fiber, covered yarn has a great demand for such products in the market. [0003] At present, commonly used coated yarns on the market include nylon air coated yarns and polyester coated yarns. Nylon air-covered yarn is a kind of characteristic yarn that is more popular in the market in recent years. It is made of spandex yarn as the core, which is wrapped and compounded with nylon filament. The interweaving of spandex and nylon not only enables the fabric to be dyed at normal temperature and pressure, avoiding damage to the fabric due to high...
