MULTIFUL COMPOUND FIBER'S MAKING METHOD

摘要

Two kinds of thermoplastic resin having different shrinkage percentage are treated to form the mixing undrawn multi-filament yarn by the conjugated spinning method. The above multi-filament yarn and the third undrawn multi-filament yarn are mixed and twisted on the heating plate with different running time and passed through the turbulent flow so that the third multi-filament yarn has different shrinkage percentage from the two kinds of multi-filament yarns.
