Preparation of side by side type polyester conjugated fiber and side by side type polyester conjugated fiber

摘要

PURPOSE: A side-by-side type polyester type conjugated fiber and a manufacturing method thereof are provided, which are characterized by solving a curved yarn, maintaining difference of extensional viscosity and having excellent crimp tendency without special modification of a spinning base. CONSTITUTION: The side-by-side type polyester type conjugated fiber is obtained by conjugated-spinning two polymers having different inherent viscosities. Polyethylene glycol having 600-40000 of degree of polymerization is used as a polymer of high viscosity ingredient. And 1-15weight of the polyethylene glycol is co-polymerized and is modified.
