Problems solved by technology

However, the recycling rate of waste textiles in my country is less than 10%, which is far from the advanced level. It is urgent to develop the waste textile utilization industry.
At present, the composition of waste textiles on the market is relatively complex, and the fibers of the composition are also various. In today's domestic and foreign markets, it is rare to see products produced by recycling waste textiles.

Abstract

The invention discloses a preliminary preparation technology utilizing waste textile for producing a fiber-based curing panel. The preparation method comprises following steps: firstly, the recycled waste textile serves as a raw material to be subject to cleaning and fluorescent disinfection, and then waste textile fiber fragments are prepared; secondly, a thermoplastic resin film is added into a pulverizer, and is pulverized into powder; thirdly, the thermoplastic resin film is heated to be in the molten state; fourthly, the waste textile fiber fragments are fed into a blender, the powdery waste thermoplastic resin film is added into the blender, a tackiness agent is added, and the waste textile fiber fragments are fully mixed with the tackiness agent; fifthly, the materials are shaped through a mold, the preliminary waste textile fiber curing panel is made, and molten thermoplastic resin is injected into the panel. The volume fraction of structure fibers can be further reduced, the panel is smaller and thinner while the toughness can be improved, generation of toxic by-products can be reduced, and the toughness of the panel can be improved.

Description

technical field [0001] The invention relates to the technical field of board production, in particular to a preliminary preparation process for producing fiber-based solidified boards from waste textiles. Background technique [0002] Waste textiles, including waste natural cotton fibers and chemical fibers, are usually disposed of as garbage. The easiest way to dispose of them is to incinerate, which is easy to pollute the air and requires a lot of treatment costs. [0003] As a new mode of economic growth in the cotton textile industry, the comprehensive utilization of waste textiles has received great attention in the industry. The comprehensive utilization of waste textiles is an effective way for the cotton textile industry to realize the development of circular economy and build a resource-saving and environment-friendly society. Organically combine the development of the industry with environmental protection, realize the fundamental change of the growth mode of the ...
