INTRODUCTION TO MULTIFILAMENT POLYPROPYLENE

Polisilk produces Polypropylene multifilament yarn. The polymer base is an isostatic polypropylene, with a high degree of purity obtained by the polymerization of Propylene.

Polypropylene formula obtained in 1954 by the Chemical Nobel Prize winner Dr. Natta.


Prof. Giulio Natta (1903-1979)

In the manufacturing process, the polymer is mixed with different protective additives, which give the yarn features comparable to the best quality synthetic yarns.

A fundamental characteristic of POLISILK PP yarn is its ECOLOGICAL character, which permits its total destruction without harming the enviroment.
