CN2622213Y - Hollow yarn - Google Patents

Abstract

A hollow yarn is spinned by means of mixing, drawing and twisting of the water-soluble fibre and the textile fibre, the fibre is twisted in the form of screw, and the middle of the twisted yarn body is hollow. The hollow yarn has the advantages of high specific surface, large coverage of yard thread, high flexibility and super soft effect, and due the existence of the air isolation film, the yarn thread has good warm performance.

Description

Hollow yarn

Technical field:

The present invention relates to textile technology, is a kind of yarn with property, specifically, is a kind of yarn with hollow, hollow effect.

Background technology:

The fashion trend of current textiles has following characteristics: high-tech, functional, main flow that the environment-friendly type textiles has become 21 century.Because consumer's pursuing individualityization, the product variety variation has become inexorable trend, advocates on raw material mix " chemical fibre combines with natural fabric ".Note the development and utilization of new fiber more, natural fabric develops to deep processing, fine finishining direction, produces surcharge by deep processing, increases economic efficiency.The research of yarn as the main aspect of textile development, is paid attention to always widely, and annual in the world various new type yarns emerge in an endless stream, and have greatly enriched the exploitation of textiles.Three aspects of the general branch of the exploitation of yarn: the one, to high branching development, the 2nd, to the development of functional aspect, the 3rd, develop to outward appearance pattern aspect.The yarn that various structures occurred just like stretch yarn, the spinning of match sieve, cladded yarn, closely spin or the like and various Fancy Yarns just like slub yarn, Chenille Yarns, particle yarn, AB melange yarn or the like.And develop new product and become an important trend by changing yarn texture.At present, Japan, Italy, Korea S, Australia etc. have very dark research in this respect, and some domestic weaving scientific research institutions and some competent enterprises are also in research and development energetically.

The utility model content:

The purpose of this utility model provide a kind of area coverage with high specific area, yarn big, have high elasticity and super soft effect, the hollow yarn of good heat-insulating property arranged.

Technical solution of the present utility model is: a kind of hollow yarn is characterized in that: form by water-soluble fibre and textile fabric mixing, drawing-off, twisting spinning, and fiber curl twisted, the middle part of the yarn body that twisted becomes is hollow shape through post processing.

Water-soluble fibre described in the utility model and the textile fabric weight ratio when mixing spinning is 1: 0.05～0.30.Textile fabric be cotton fiber or wash, glue, fiber crops, wool fibre etc.Their hybrid modes are that bar mixes, and before mixing cotton fiber are carded to sliver; Water-soluble fibre is carded to yarn.Water-soluble fibre adopts short fiber.

The beneficial effects of the utility model are: have high specific area, the area coverage of yarn is big; Have high elasticity, super soft effect; Because the existence of air insulated film is arranged, and this yarn has good heat-insulating property.Has good economic, practical property behind the fabric that processes.Owing to utilized water-soluble fibre when spinning, to make stuffing preferably, after loose formula arrangement, have certain cementation, kept the hollow form of peculiar hollow preferably.Make yarn have better bulkiness, both increased the elasticity of yarn, increased the flexibility of yarn again,, also just increased the capillarity of yarn, improved the water imbibition of yarn owing to bulkiness (the being degree of hollowness) height of yarn.

The utility model is described in further detail below in conjunction with embodiment:

Description of drawings:

Fig. 1 is the contour structures schematic diagram of a kind of hollow yarn of the present utility model;

Fig. 2 is the cross-sectional structure schematic diagram of hollow yarn of the present utility model.

The specific embodiment:

Fig. 1, Fig. 2 have described an embodiment of the present utility model jointly, in this embodiment, hollow yarn forms fiber curl twisted by water-soluble fibre and textile fabric mixing, drawing-off, twisting spinning, the middle part of the yarn body 1 that twisted becomes is hollow shape, and promptly there is cavity 2 in the position therebetween.Water-soluble fibre and the textile fabric weight ratio when mixing spinning is 1: 0.10～0.20 (or other suitable weight ratio, as 1: 0.05～0.30).Textile fabric be cotton fiber or wash, glue, fiber crops, wool fibre.Their hybrid modes are that bar mixes, and before mixing cotton fiber are carded to sliver; The yarn of water-soluble fibre for making through combing.

Manufacturing process:

Earlier cotton or other textile fabric are spun into sliver through scutching cotton, comb and parallel cotton fibers prior to spinning.Simultaneously, also water-soluble fibre (as the short fiber water soluble vinylon) is carded to yarn,, removes most of water-soluble fibre, produce hollow form through loose formula arrangement then by operations such as silver mixing, rove, spun yarn, winders.Pine formula arrangement is with the yarn behind winder, makes reeled yarn, reeled yarn is put in the hot water, and the molten soluble fiber that anhydrates, temperature＜100 ℃, 20～30 minutes time, and control certain bath raio (as 1: 10).

Claims (2)

1, a kind of hollow yarn is characterized in that: by textile fabric curl twisted structure, the middle part of the yarn body that twisted becomes is hollow shape.

2, hollow yarn according to claim 1 is characterized in that: textile fabric be cotton fiber or wash, glue, fiber crops, wool fibre.
