Reasons why non-woven fabrics cannot be reused
Non woven fabrics break through traditional textile principles and have the characteristics of short process flow, fast production rate, high yield, low cost, wide use, and multiple sources of raw materials.
Non woven fabrics break through traditional textile principles and have the characteristics of short process flow, fast production rate, high yield, low cost, wide use, and multiple sources of raw materials. What is the reason why this material cannot be reused?
1. Changes in internal microscopic properties
Green non-woven fabrics are usually made of composite materials. The main material of the fabric is polypropylene, which is processed through melt blown and spunbonded technology. The microstructure is fine plastic fibers. In the case of high-temperature shrinkage, it is a characteristic of plastic products, but high-temperature plastics are not. High temperature resistance is a relative concept, so non-woven fabrics will undergo corresponding shrinkage reactions on micro fabrics.
2. The sterile barrier performance will be lost after use
Non woven fabrics are processed using melt blown and spunbonded methods, with a microstructure of fine plastic fibers. Shrinkage after high temperature is a characteristic phenomenon of plastic products. There is no high-temperature resistant plastic, and high-temperature resistance is a relative concept, so non-woven fabrics will have corresponding shrinkage reactions at the micro level.
Non woven fabrics can use their small pores to purify air and block bacteria and viruses. Cut off the pommel balls with scissors to avoid irreparable damage when offline. I hope the above content is helpful to you.
