The raw material used in fabric making is polypropylene.
Polypropylene is a thermoplastic polymer that has a wide range of applications from parts used in the automotive industry to textile and food packaging.
Chemical And Physical Properties Of Polypropylene
The most common commercial polypropylene has a level of crystal structure between low density polyethylene (LDPE) and high density polyethylene (HDPE). The Young’s modulus (modulus of elasticity) is also moderate. However, it is less stiff than LDPE and much less loose than HDPE. This allows the use of polypropylene in place of engineering plastics such as ABS.
Polypropylene is very resistant to fatigue. Low cost, good impact resistance. The coefficient of friction is low and provides very good electrical insulation. Chemical resistance is good. Suitable for all thermoplastic processing processes. Polypropylene has a melting temperature of about 160 degrees Celsius. However, it has the following disadvantages. Low UV radiation resistance, high thermal expansion. Paint and coating are difficult. It is resistant to outdoor weather conditions and is open to oxidation. It is flammable and interacts with chlorine-containing solvents.
