Embodiment

[0020] Several examples are listed below, however, the scope of the present invention is not limited thereto.

[0021] With the reeling device described in JP-A-2004-312060, the temperature of the reeling release part of the reeling tank is maintained at about 38° C. As cocoon silk, the cocoon silk was shaken out from the swollen cocoon at a reeling speed of 50 m / min, and covered with degummed tussah silk yarn without applying any tension to the yarn in the reeling process. As the tussah silk yarn, commercially available degummed tussah silk yarn (from Sanka Seiren Co., Ltd.) was used.

[0022] In the process of winding to the small yarn spool, the cocoon silk covered by tussah silk yarn and in a swollen state is dried, and the domestic silk yarn containing sericin as the core yarn and the tussah silk yarn for covering pass through The sericin is fusion bonded to obtain an entangled yarn, which is then respun.

[0023]In Table 2 below, the performance test results of the deg...

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

field of invention [0001] The present invention relates to a method for manufacturing cohesioned silk yarn and the cohesioned silk yarn and products thereof. In the method, the core yarn and the covering yarn of the cohesioned silk yarn are both made of silk Formed and all bonded by sericin. Background of the invention [0002] When twisting raw silk, the yarn is bundled and stabilized for easy handling, so it has excellent weaving and knitting processes. However, the twisting causes the yarn to become restrained and stiff, resulting in a strong and durable fabric, but with a relatively stiff hand. On the other hand, when untwisted raw silk is used after degumming to obtain soft-touch fabrics, the yarns are scattered and thus cannot be used for degummed woven or knitted fabrics. The untwisted raw silk can be applied to post-degummed woven fabrics, but it is not suitable as a commercial product due to friction and irregular fluffing, etc. [0003] Under the above circumsta...
