Abstract

The invention relates to the field of recycling waste textiles, in particular, it provides a waste spinning regenerated composite fiberboard and its preparation method and application. The invention provides a method for preparing waste spinning regenerated composite fiberboard. Combining the two non-woven processes of carding and air laying, waste spinning chemical fibers and low melting point fibers are used to prepare the first fiberboard, waste spinning fibers and low melting point fibers The second fiber board is prepared, and then the two are combined to obtain a waste spinning regenerated composite fiber board. The preparation method improves the adaptability of the waste spinning fiber and the production process, better solves the problem of low recycling rate of waste textiles in the prior art, realizes 100% utilization of waste textiles, and avoids the use of rubber powder at the same time. Formaldehyde pollution will not be generated during the production process and subsequent use. The waste spinning regenerated composite fiber board provided by the invention has sound insulation, sound absorption and heat preservation performances, and is pollution-free.

Description

Waste spinning regenerated composite fiber board and its preparation method and application technical field The present invention relates to waste textile recycling field, specifically, relate to a kind of waste spinning regenerated composite fiberboard and preparation method and application thereof. 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 Dressing concepts are changing with each passing day, and the life cycle 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. There are various sources of waste textiles, mainly including: in the process of clothing and raw material processing, due to chemical operations and mechanical During processing, waste fabrics will inevitably be produced. Such fabrics are less pollut...
