Cohensioned silk yarn and silk knit cloth

Abstract

The present invention provides a yarn which is a covering yarn consisting of only silk and a yarn containing sericin. A cohesioned silk yarn is obtained by using raw silk, as a core yarn, with sericin in swollen state in reeling process at reel speed of 20 to 100 m/min, and by covering a raw silk in said reeling with a wild silk yarn, and by fusion-bonding a raw silk and a wild silk yarn by sericin. Said cohesioned silk yarn can be subjected to automatic knitting.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a method for producing a cohesioned silk yarn wherein both a core yarn and a covering yarn are made of silk and both are bonded by sericin, along with said cohesioned silk yarn and products thereof. [0003] 2. Prior Art [0004] When a raw silk is twisted, yarns are bundled and stabilized and provides an easy handling, therefore, gives a good weaving and knitting process, on the contrary, the twisting makes a yarn restricted and harder, therefore, the products from them provide a sturdy cloth but relatively hard feeling. On the other hand, when the non-twisted raw silk is used after degumming to obtain a cloth with soft feeling, yarns are scattered and thus cannot be utilized for the degummed woven fabric or knit fabric. It may be applied to the post-degumming woven fabric but provides unsuitable commercial products due to friction and irregular fuzz. [0005] In the above circumstance, m...

AI Technical Summary

Benefits of technology

[0010] A cohesioned silk yarn of the present invention is a covering yarn composed of only silk and is a yarn not only superior in skin feeling, heat retaining property and water absorption inherent to silk but also has, due to containing sericin, function such as oxidation resistance, antibacterial action, whitenin

Problems solved by technology

However, knit products using raw silk with remaining sericin were not present because the yarn before degumming is hard and difficult to knit.
