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 degrees C.
