Abrasive filaments and production process thereof.

摘要

Abrasive filaments made of a composition which comprises 95 - 70 vol.% of a polyvinylidene fluoride resin, whose inherent viscosity ( eta inh) ranges from 0.9 to 1.4, and 5 - 30 vol.% of abrasive grains. They are produced by melt-spinning the composition and then stretching the resultant filaments at a draw ratio of 2.5 times - 5.5 times within a temperature range of 100 - 200 DEG C.
