The particularity of polypropylene non-woven fabric structure

There are many types of non-woven fabrics. According to different industry needs, the types of non-woven fabrics produced also have their own characteristics, and polypropylene non-woven fabrics have good permeability and tensile strength, and polypropylene non-woven fabrics have their own characteristics. It has a lot to do with its special structure. The special structure of polypropylene non-woven fabric: 　　 1, three-layer structure, surface reinforcement 2, core layer-the main waterproof layer uses linear low-density polyethylene (LLDPE) with high branch ratio (more macromolecular side chains), Its extensibility, impermeability, flexibility, puncture resistance and low temperature resistance are good.　　3. The surface is made of polypropylene non-woven fabric. Through the composite with the core layer, the insufficient linear expansion coefficient of polyethylene is solved. The surface roughness of the product is increased, the friction coefficient of the product is improved, and the bonding problem of the composite coil is solved, and cement bonding is realized.　　 Buy all kinds of non-woven fabrics, Non-Woven Fabric Co., Ltd. is worth your trust!
