Document Type and Number:
Japanese Patent JPH04331248
Kind Code:
A
Abstract:
PURPOSE:To obtain a polypropylene(PP) composition having satisfactory suitability to both dyeing and spinning by blending PP, an acid-modified PP, and a specific polyamide to disperse the polyamide into the PPs. CONSTITUTION:A polypropylene(PP) composition which comprises PP (A) (preferably crystalline PP from the standpoint of obtaining fibers having sufficient strength), an acid-modified PP (B) (e.g., one obtained by grafting an alpha,beta-unsaturated acid such as maleic anhydride, with the grafted acid amount being 10X10<-6> to 10X10<-4>mol/g), and a polyamide (C) having a terminal amino group content of 60X10<-6>eq/g or more. In preparing the PP composition, 50-80wt.% PPs (A) and (B) are kneaded with 20-50wt.% polyamide (C) to disperse and polyamide as the island component in the PPs as the sea component until the dispersed polyamide particles come to have diameters of 1mum or less. The PP composition thus obtained has satisfactory suitability to both dyeing and spinning.
