The characteristics and uses of pp spunbond non-woven fabric
PP spunbond non-woven fabric is a kind of non-woven fabric. It means that after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a network, and the fiber network is then bonded to itself. Bonding, thermal bonding, chemical bonding or mechanical reinforcement methods can turn the fiber web into a non-woven fabric.
PP is called polypropylene. It is a polymer made of propylene monomer through free radical polymerization. It has a non-toxic, odorless, tasteless, milky white and highly crystalline shape, and is a crystalline material.
PP spunbond non-woven fabric is a non-woven fabric made of polypropylene material.
It has the characteristics of high strength, small difference in vertical and horizontal strength; acid and alkali resistance, non-toxic, harmless to human physiology; excellent breathability; liquid dyeing, non-fading and other characteristics! ?PP spunbond non-woven fabric has good heat resistance, with a melting point of 164~170℃, and the products can be sterilized at temperatures above 100℃.
It will not deform at 150℃ without being affected by external force.
The embrittlement temperature is -35°C. Embrittlement will occur below -35°C, and the heat resistance is not as good as PE.
