A HIGH FUNCTIONAL U-TYPE CONJUGATED YARN

摘要

A high functional U-type conjugated yarn consists of a fiber forming polymer, whose inner and outer polymers has a different heat contractibility, such as homo-polymer or co-polymer of nylon 6, nylon 66 and polyhexamethylenediamine sebacamide. It is 500 2000 poise to the difference of their melt viscosity for the heat contractibility difference between the inner polymer and outer polymer.
