Embodiment Construction

[0009] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0010] see figure 1 , a PBT filament core-spun yarn, comprising: a PBT filament 1 covered with a yarn fiber layer 2 outside the PBT filament 1 . The PBT filament 1 is made of PBT fiber. The PBT filament core-spun yarn in the invention is acid-resistant, chlorine-resistant, has the excellent characteristics of "low draft, high elasticity", and has excellent coloring performance and fabric dimensional stability.

[0011] Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embod...

Abstract

The invention discloses polybutylene terephthalate (PBT) filament core-spun yarn comprising PBT filament which is coated with a yarn fiber layer. The PBT filament core-spun yarn disclosed by the invention is resistant to acid and chlorine, has the characteristics of low drafting and high elasticity and has the advantages of good colorability and fabric size stability.

Description

technical field [0001] The invention relates to a PBT filament core-spun yarn. Background technique [0002] The currently commonly used spandex core-spun yarn is made of spandex filament as the inner core and the outer yarn fiber layer; its production method is: feeding the short fiber roving into the drafting zone from the back roller, feeding 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. The defect of this kind of spandex core-spun yarn is: because the spandex filament is not acid-resistant, chlorine-resistant, and has poor coloring performance, the core-spun yarn made of spandex filament is not suitable for fine bleaching, low-temperature dyeing and other varieties. [0003] Therefore, it is necessary to provide a PBT filament core-spun yarn that solves the above-me...
