Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] As shown in Figure 2, the structure of the siro-spun spandex core-spun slub yarn of the present invention includes: comprising: a central spandex filament 3 covered with a yarn fiber layer on the outside of the central spandex filament 3, the yarn The fiber layer is composed of two strands of whiskers 31 and 32 wound and twisted at intervals. In actual production, the two strands of strands 31 and 32 may be different fibers, or the same fibers or two fibers with the same blending ratio.

[0015] As shown in Figure 1, the production method of the above-mentioned siro spinning spandex core-spun yarn is briefly described as follows: the two rovings respectively wound on the two spindles 51 and 52 are kept at a certain distance and fed into the same drafting area of ​​the spinning frame in parallel, Carry out drafting, pass back roller 6, m...

Abstract

The present invention discloses a cellophane polyurethane fiber core-spun yarn. Said cellophane polyurethane fiber core-spun yarn is unique in style, possesses advantages of cellophane yarn and polyurethane fiber core-spun yarn simultaneously and can be used as high-grade textile face fabric. Its structure is characterized by that its center is polyurethane fiber yarn, and the exterior of said central polyurethane fiber yarn is covered with yarn fiber layer, and said yarn fiber layer is made up by using two strands of fiber through a certain winding and twisting process.

Description

technical field [0001] The invention relates to a siro spinning spandex core-spun yarn. Background technique [0002] Spandex yarn belongs to polyurethane fiber, which is a kind of high elastic fiber. The biggest characteristic of spandex fiber is that it has great elongation, and when stretched slowly, its elongation can reach a maximum of 450-600%. After removing the force and relaxing It can be quickly restored to its original state. [0003] The currently commonly used spandex core-spun yarns all use spandex filaments as the inner core and the outer yarn fiber layer; the production method is: feed the short fiber roving into the drafting zone from the back roller, and feed the spandex filament from the front roller, and The staple fiber roving strands after drafting are merged and twisted to form spandex core-spun yarn. Natural fibers such as cotton, wool, hemp, and silk can be used for the outsourced short fiber roving. Spandex core-spun yarn has good elongation and ...
