Abstract

The invention relates to master batches capable of removing VOCs in recycled polyester under the conditions of light and darkness. The master batches are prepared from, by mass, 60-75% of polyester, 10-15% of aldehyde inhibitor modified activated carbon, 12-19% of rare earth element doped photocatalyst, 2-4% of heat stabilizer, 2-4% of ether inhibitor and 1-2%% of zinc stearate, wherein the rare earth element doped photocatalyst is composed of a rare earth compound, a photocatalyst and a photocatalyst dispersing agent, and the master batches comprise, by mass, 2-4% of photocatalyst dispersingagent. When added into the recycled polyester, the master batches can efficiently remove the VOCs in the recycled polyester under the conditions of light and darkness. The production process is simple, the VOCs in the recycled polyester can be efficiently removed, and the popularization value is very high.

Description

technical field [0001] The invention belongs to the field of regenerated polyester and relates to a masterbatch capable of removing VOCs in regenerated polyester under both light and dark conditions. Background technique [0002] Since polyester fiber came out, it has developed rapidly because of its excellent performance, and its output has become the crown of synthetic fiber in the world. Polyester fiber has a series of excellent properties such as high breaking strength, high elastic modulus, moderate resilience, excellent heat setting performance, good heat resistance, good light resistance, good acid and alkali resistance and good corrosion resistance. The fabric prepared by it has the advantages of good wrinkle resistance and stiffness, so polyester fiber is widely used in the fields of clothing and home textiles. [0003] Recycled polyester is processed from recycled polyester bottles, filament waste or waste cloth. It belongs to the recycling and reuse of polyester ...
