Problems solved by technology

[0005] The disadvantages of the above two kinds of yarns are: the style is single, and they cannot have multiple advantages. Usually, they can only be used for ordinary textile fabrics, and cannot be used for high-grade textile fabrics.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, the structure of the spandex core-spun particle yarn according to the present invention includes: spandex filament 51, the outer side of the spandex filament 51 is covered with a yarn fiber layer 52, and the yarn fiber layer 52 is also provided with raised particles at intervals. Paragraph 53. The particle segments 53 may be particles with equal diameters, particles with reduced diameters, or particles with different diameters.

[0014] Such as figure 2 As shown, the production method of the spandex core-spun particle yarn is as follows: the roving wound on the spindle 5 is fed into the same drafting area of ​​the spinning frame, and drafted, first passing through the rear roller 6, the middle roller 7, and then by the front roller Roller 8 outputs single yarn sliver. During this process, the particle gene...

Abstract

The invention discloses spandex core-covered knot yarn which has unique and diverse style and the advantages of spandex core-covered yarn and knot yarn and can be used for high-quality textiles. The spandex core-covered knot yarn comprises spandexes outside which a yarn fiber layer coats, and raised knot sections are also arranged on the yarn fiber layer at intervals. The spandex core-covered knot yarn also has the advantages of the spandex core-covered yarn and the knot yarn, i.e. the spandex core-covered knot yarn has favorable extensibility and retraction, the unique style of the knot yarn, strong spotted stereoscopic impression of a cloth cover, special style and strong individuation. Therefore, the spandex core-covered knot yarn can be widely used in many high-quality textiles.

Description

technical field [0001] The invention relates to a spandex core-spun particle yarn. Background technique [0002] Spandex yarn belongs to polyurethane fiber, which is a kind of high elastic fiber. The biggest feature of spandex fiber is that it has great elongation, and when it is stretched slowly, its elongation can reach a maximum of 450-600%. 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 retractability, and at the same time has goo...
