Concentrate for the preparation of modified polypropylene fibers with calcium carbonate and its use

摘要

It is described a concentrate contains a polypropylene matrix from 40 to 86.7% wt., calcium carbonate from 4 to 38 wt.%, the color pigments of 0.3 to 30% by weight and a polyethylene wax from 5 to 20% wt. as dispersant. It is usefull for the preparation of modified polypropylene fibers dyed in the mass and for applications in textile articles, wherein the concentrations of the calcium carbonate in polypropylene fiber is from 0.28 to 3.8% by weight.
