METHOD FOR MANUFACTURING ARAMID COMPOSITE YARN WITH ENHANCED ELASTICITY AND BULKINESS, ARAMID COMPOSITE YARN PRODUCED THEREBY, AND FABRIC USING THE ARAMID COMPOSITE YARN

摘要

The present invention relates to a manufacturing method of aramid composite yarn with improved elasticity and bulkiness by providing an aramid fiber with a crimp after degumming, untwisting, and heat setting, an aramid composite yarn manufactured thereby, and a fabric manufactured by using the aramid composite yarn. According to the present invention, an aramid composite yarn is heat set when twisting in the process of degumming and untwisting, thereby artificially providing a crimp with various and abundant forms of a curved surface, elasticity and bulkiness of an aramid composite yarn is excellent, and maintaining excellent strength and elasticity without depleting due to heat setting at low temperatures. A fabric of the present invention manufactured with an aramid composite yarn with a high ratio of elasticity can be applied to various uses required for wearability, activity, or the like.
