Abstract

The utility model discloses a high-elasticity yakwool knitting yarn. PTT (Polytrimethylene Terephthalate) endless tows are arranged inside a yarn body; and outsides of the PTT endless tows are tightly coated with yakwool fibers. The high-elasticity yakwool knitting yarn disclosed by the utility model has the advantages that insides of the yakwool fibers are coated with the PPT endless tows, so that the yakwool knitting yarn has excellent elasticity; and the PTT filaments in the PTT endless tows are mutually wound with the yakwool fibers on the outer sides of the PTT endless tows and bare filaments are greatly reduced, so that the yakwool fibers on the outer sides of the PTT endless tows are coated more tightly. Compared with a traditional spandex core-spun yarn, the high-elasticity yakwool knitting yarn has the advantages of higher flexibility, better dimension stability, easy dyeing, avoidance of appearance grounding of textile and the like. The high-elasticity yakwool knitting yarn disclosed by the utility model is suitable for producing clothes such as corsetry, stretch trousers and stretch socks.

Description

A kind of high-elastic yak knitting yarn

Technical field

The utility model relates to weaving fancy yarn field, relates in particular to yak knitting yarn.

Background technology

Yakwool is the distinctive textile raw material of China, adopted on one's body by the yak that lives in the pure high altitude localities of environment, and is pollution-free, pure, noble; Yakwool fiber has softness, slides characteristics glutinous, fluffy insulation, have the characteristic similar with cashmere, but yakwool fiber is short partially; For a long time, common product mainly is the yak hand-knitting wool, yak down sweater, trousers; Slubbing series products such as yakwool overcoating; Product is single, and added value is low, does not realize the application of yakwool fiber at high-grade fabric.

The utility model content

The purpose of the utility model is: a kind of simple in structure, unique style is provided, has splendid flexible high-elastic yak knitting yarn.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of high-elastic yak knitting yarn, yarn body set inside has the PTT endless tow, closely is coated with yakwool fiber in the outside of PTT endless tow.

Further, aforesaid a kind of high-elastic yak knitting yarn, wherein, described PTT endless tow is made up of 12-24 PTT long filaments, and the fineness of described PTT long filament is 3.3-7.7tex.

The utility model has the advantages that: coat the PTT endless tow in the yakwool fiber; Make yak knitting yarn have splendid elasticity; And the PTT long filament in the PTT endless tow can with the mutual looping of the yakwool fiber in the outside, significantly reduce naked silk, make the yakwool fiber in the PTT endless tow outside coat tightr; Compare with traditional spandex core-spun yarn, have more soft, better DIMENSIONAL STABILITY, be easy to advantages such as dyeing, fabric is not show-through.

Description of drawings

Fig. 1 is the structural representation of the described a kind of high-elastic yak knitting yarn of the utility model.

Fig. 2 is the cross-sectional structure sketch map of the described a kind of high-elastic yak knitting yarn of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.

Like Fig. 1, shown in Figure 2; A kind of high-elastic yak knitting yarn; Yarn body set inside has PTT endless tow 1; The outside in PTT endless tow 1 closely is coated with yakwool fiber 2, is 12-24 as the quantity of PTT long filament in the described PTT endless tow 1 of preferred version, and wherein the fineness of PTT long filament is 3.3-7.7tex.The Chinese of PTT is for gathering the terephthalyl alcohol propylene glycol ester, and the PTT long filament is and gathers the terephthalyl alcohol propylene glycol ester fiber.The production method of above-mentioned high-elastic yak knitting yarn is following: on sir jet spinning machines, yakwool rove bar is after the drafting system drawing-off, and the yarn of formation and PTT endless tow 1 are superimposed; Get into nozzle through preceding jaw together; Looping is twisted into high-elastic yak knitting yarn each other in nozzle, because the effect of secondary nozzle air-flow makes peripheral yakwool fiber can get into endless tow inside; Realize inside and outside looping, naked silk phenomenon is few.Compare with traditional spandex core-spun yarn, that the described high-elastic yak knitting yarn of the utility model has is more soft, better DIMENSIONAL STABILITY, be easy to advantages such as dyeing, fabric is not show-through.The utility model is applicable to dress ornaments such as making Lingerie, stretch pants, stretch socks.

Claims

1. high-elastic yak knitting yarn, it is characterized in that: yarn body set inside has the PTT endless tow, closely is coated with yakwool fiber in the outside of PTT endless tow.

2. a kind of high-elastic yak knitting yarn according to claim 1 is characterized in that: described PTT endless tow is made up of 12-24 PTT long filaments, and the fineness of described PTT long filament is 3.3-7.7tex.
