Polypropylene is the smallest of the total relative density of all synthetic fibers, so it is the lightest weight, the unit weight of the fiber can cover the largest area. Its strength and high strength varieties of synthetic fiber polyester, nylon similar, but in the wet state of strength does not change, which is better than nylon. But its abrasion resistance is second only to nylon, and its abrasion resistance is somewhat poor, and it has remarkable stability to inorganic acid and alkali. Elasticity is good, moisture absorption is very small, fabric shrinkage is small. There are excellent electrical insulation and mechanical properties, a large number of industries used to manufacture rope, packaging materials, fishing nets, parachutes and so on. Of course, polypropylene has its shortcomings, poor light resistance, poor dyeing, electrostatic large, poor flame resistance, dyeing difficulties.
       2. The production of polypropylene fiber Polypropylene fiber solution polymerization method is made. The thermal decomposition temperature of 350 ~ 380C, the melting point of 150 ~ 176C, so the use of soft spinning.
      3. Polypropylene material washing Polypropylene washing can not be soaked in boiling water, not dry cleaning, a wash will be hard.
