Abstract
Procedeu de obtinere a fibrei poliacrilonitrilic vopsita în masa caracterizat prin aceea ca în scopul sporirii gradului de uniformitate al distributiei în masa de filare a pigmentului se foloseste o pulbere uscata de pigment înglobat în poliacrilonitril torniota prin filarea prin extrudere a unui amestec continînd 13....20% pigment plus poliacrilonitriluluiavînd o viscozitate 10....200 P si o temperatura de 50....100 degree C dupa care urmeaza precipitarea prin coagulare, etirarea, spalarea, avivarea, uscarea si maruntirea.Process for obtaining a polyacrylonitrile fiber painted in the mass characterized in that in order to increase the degree of uniformity of the distribution in the spinning mass of the pigment a dry powder of pigment embedded in the polyvinylpyrrolidone is used by extruding a mixture containing 13 ... .20% pigment plus polyacrylonitrile having a viscosity of 10 ... 200 P and a temperature of 50 ... 100 ° C followed by precipitation by coagulation, etching, washing, soaking, drying and crushing.
