Nylon filament core-spun knot yarn

Abstract

The invention discloses a nylon filament core-spun knot yarn. The yarn comprises a nylon filament, wherein a yarn fiber layer covers the outer side of the nylon filament; and raised knot segments are also arranged on the yarn fiber layer at intervals. The yarn has the following beneficial effects: the yarn is resistant to acid and chlorine and has good extensibility, shrinkage and dimensional stability; and the fabric prepared from the yarn not only has good handfeel, but also has strong three dimension and good visual effect.

Description

technical field [0001] The invention relates to a nylon filament core-spun particle 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. The outsourced short fiber roving can be made of natural fibers such as brocade, wool, hemp, and silk. 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. And the fabric three-dimensional feeling that makes with spandex core-spun yarn is poor, a...
