A kind of yak knitting yarn with hollow nature
Technical field
The utility model relates to weaving fancy yarn field, relates in particular to yak knitting yarn.
Background technology
Yakwool is China's distinctive textile raw material in western high altitude localities; Have the advantages that gloss is soft, elasticity is strong, the feel cunning is glutinous, warmth retention property is good; But compare with cashmere, fibre fineness is thick slightly, elastic modelling quantity is big, extension at break is little, fiber curling less and wrapped configuration is irregular, be easy to generate static than resistance height, these characteristics determined yakwool lining kimonos be contained in the use fluff easily, balling-up; Fabric stiffness is big, flexibility is not enough; Cause finished product of low grade, this raw material is mainly used in slubbing yak down sweater, trousers and a small amount of yakwool overcoating etc. for a long time, and added value is low.
Yak down yarn is carried out flexibility improves and can make the yakwool goods have the style and features identical with cashmere product, thus improve greatly this fibrous raw material the application space, promote added value of product.
The utility model content
The purpose of the utility model is: provide a kind of simple and reasonable, can make fabric have the yak knitting yarn with hollow nature of similar elasticity with cashmere fabric and flexibility.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of yak knitting yarn with hollow nature, the core of yakwool fiber yarn body is provided with water-soluble vinylon long tow.
The utility model has the advantages that: after in yakwool fiber yarn body, being provided with water soluble vinylon; The lining that is made into water-soluble vinylon long tow in 60-80 degree water moves back dimension, forms through hole shape hole in the yakwool fiber yarn body in the lining, and through hole shape hole has the effect of stored air; Elasticity, flexibility and the thermal property of lining have been improved; And lining is frivolous, has the ultra soft feel close with pure-wool cashmere, meets the mass consumption demand.
Description of drawings
Fig. 1 is the described a kind of structural representation with yak knitting yarn of hollow nature of the utility model.
Fig. 2 is the structural representation after the water soluble vinylon in the described a kind of yak knitting yarn with hollow nature of the utility model moves back dimension.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
As shown in Figure 1, a kind of yak knitting yarn with hollow nature, the core of yakwool fiber yarn body 1 is provided with water-soluble vinylon long tow 3, and wherein the consumption of water-soluble vinylon long tow 3 is 10%-20% of yakwool fiber yarn body 1 weight.Above-mentioned production method with yak knitting yarn of hollow nature is: on ring throstle, yakwool rove bar is after rear roller, middle roller drawing-off, and the yarn of formation and water-soluble vinylon long tow 3 are superimposed; Get into front roller nip together, grip output, through twizzle and steel traveler twisting by front roller; Yakwool fiber yarn body 1 promptly tightly is coated on the outside of water-soluble vinylon long tow 3, forms the described yak knitting yarn with hollow nature of present embodiment, after above-mentioned yak knitting yarn with hollow nature is made into fabric; In 60-80 ℃ of water, water-soluble vinylon long tow 3 dissolvings, promptly water-soluble vinylon long tow 3 moves back dimension; The core that moves back the yakwool fiber yarn body 1 after the dimension forms through hole shape hole 2, and as shown in Figure 2, through hole shape hole 2 has the effect of stored air; Elasticity, flexibility and the thermal property of lining have been improved; And lining is frivolous, has the ultra soft feel close with pure-wool cashmere, meets the mass consumption demand.
