Abstract

The invention relates to the field of waste textile recycling, and particularly provides a waste spinning regenerated composite fiberboard and a preparation method and application thereof. The invention provides a preparation method of a waste spinning regenerated composite fiberboard. The preparation method combines two non-woven processes: carding lapping and airflow lapping, prepares a first fiberboard from waste spinning chemical fibers and low-melting-point fibers, prepares a second fiberboard from waste spinning fibers and low-melting-point fibers, and combines the first fiberboard and the second fiberboard to obtain the waste spinning regenerated composite fiberboard. The adaptability of the waste spinning fibers and a production process is improved by the preparation method, the problem of low reutilization rate of waste textiles in the prior art is better solved, 100% utilization of the waste textiles is realized, meanwhile, the use of rubber powder is avoided, and formaldehyde pollution is not generated in the production process and subsequent use. The provided waste spinning regenerated composite fiberboard has sound insulation, sound absorption and heat preservation properties, and is pollution-free.

Description

technical field [0001] The invention relates to the field of recycling waste textiles, in particular to a waste spinning regenerated composite fiber board and its preparation method and application. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the consumption of clothing continues to increase. People's clothing concepts are changing with each passing day, and the service life of textiles is greatly shortened, resulting in a gradual increase in the use of textile fibers. At the same time, waste textiles are also increasing day by day. [0003] There are many sources of waste textiles, mainly including: during the processing of clothing and raw materials, due to chemical operations and mechanical processing, waste cloth will inevitably be produced. This type of cloth is less polluted and the pre-treatment process is relatively simple; waste clothing, carpets And bed sheets are the main sou...
