Abstract

Prezenta inventie se refera la realizarea unui polietilentereftalat, sub forma de pulberi fine, utilizat ca suport pentru concentrate de culoare, pentru colorarea în masa a firelor si fibrelor poliesterice, cu o vâscozitate relativa în fenol: tetracloretan 3:2 de 500...820 si punct de topire de 250...265 degree C. Procedeul de obtinere porneste de la granule de polietilenterreftalat paralelipipedice sau cilindrice, care se trateaza cu alcool benzilic, se ridica temperatura si se mentine astfel pentru dizolvare, dupa care se raceste pentru precipitare, iar pulberea fina formata se filtreaza, se spala, se usuca, se disperseaza mecanic si se siteaza.
