With the development of the clothing industry, more and more wastes such as discarded old clothes, leather fabric scraps and shoe factory scraps in the production process are produced. If it is directly incinerated or landfilled, it will cause environmental problems and waste. A large amount of clothes can be crushed and used for incineration to generate electricity, or for recycling and papermaking. This not only reduces solid waste pollution, but also effectively utilizes renewable resources. Among them, the crushing process in the early stage of garment waste treatment is an important procedure for recycling.
