Description

Technical Field

[0001] This utility model relates to the field of chemical fiber technology, and in particular to a recycled polyester composite filament. Background Technology

[0002] Regenerated fiber refers to textile fibers inspired by silkworm spinning. They are made from natural high-molecular compounds such as cellulose and protein as raw materials, chemically processed into a concentrated polymer solution, and then spun and post-processed. This process allows waste fibers to be reused to produce new fibers that meet the requirements, making it green and environmentally friendly.

[0003] However, the extraction of raw materials for recycled fibers is currently difficult, the production cost is high, and the recycled fibers produced are prone to wrinkles and creases that are not easy to recover, and are also prone to mold and deterioration.

[0004] The existing patent publication number (CN115142162A) discloses a recycled polyester composite antibacterial polyester filament and its production process. This invention relates to the field of spinning production, including a polyester core filament with an outer sheath layer polymerized on its outer side. The bamboo fiber filaments covering the polyester core filament of this invention have antibacterial and antibacterial effects. The polyester covering filament can improve the overall strength of spinning, increase abrasion resistance, and reduce wrinkles. The mixed antibacterial agent in the polyester core filament can kill and inhibit microorganisms. The outer sheath layer can keep the polyester core filament dry. Nano-phase change microcapsules can control the spinning temperature within a certain temperature range, creating a microenvironment unfavorable to bacterial growth. The production process is a physical method, in which the collected waste material is first melted and filtered to remove impurities, then thickened in a liquid phase, and then spun. Compared with the traditional physical method of recycled spinning, the quality is better and the cost is lower.

[0005] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content
