Description

Body shaping fabric and yarn

Technical Field

The utility model relates to a technical field of weaving especially relates to a surface fabric and yarn of getting into shape.

Background

The jeans wear is evergreen tree in the wear, and has become an irreplaceable role on the wear stage after more than one hundred years of development and cultural precipitation. The traditional denim fabric is formed by interweaving indigo pure cotton warp yarns and white cotton weft yarns for three times, but with the development of the society and the improvement of the living standard of people, the traditional coarse-count twill pure cotton denim does not meet the pursuit of people on the elasticity, the comfort and the like of clothes.

For the elastic jean fabric, the elastic elongation rate of more than 45 percent belongs to the high-elasticity jean fabric, the existing high-elasticity jean fabric generally has the problems of high shrinkage rate, high growth rate and small fabric width, the shrinkage rate is generally about-13 percent and is difficult to control within-8 percent, the higher the shrinkage rate is, the more easily the fabric is curled, the unfavorable cutting is realized, the size stability of the garment is difficult to control when the fabric is sewn into the garment, the quality problem is easy to occur, and the economic loss is caused. Particularly, for the existing high-elasticity jean fabric with the elastic elongation rate of more than 70%, the lowest growth rate can only reach 6%, and after the jean fabric is made into jean clothes, the fabric is stressed greatly on parts which move frequently, such as knees, buttocks, waist and the like, in the wearing process, and the problems of arching, sagging and looseness easily occur after long-time wearing, so that the quality defect of the jean clothes is caused. Therefore, the shrinkage and the growth rate of the denim fabric are reduced as much as possible while the good elastic elongation of the fabric is ensured, so that the control of the dimensional stability of the elastic denim fabric is a common technical problem and common problem in the denim industry.

The yarn of the existing high-elasticity denim fabric usually adopts a single covering yarn to realize the high-elasticity effect, and in the composite yarn structure of the covering yarn, the position of a filament serving as the core yarn relative to a short fiber serving as an outer covering is relatively fixed, the filament cannot be transferred inside and outside the composite yarn structure to the maximum extent, so that the filament and the short fiber cannot be naturally and uniformly mixed and cohered, therefore, the composite yarn of the covering yarn has the problem of insufficient cohesive force between the filament and the short fiber, the relative slippage between the filament and the short fiber is easy to occur in the subsequent processing, the weaving efficiency is low, and the quality problem of the fabric is easy to occur.

For single-core-spun yarns, the larger the denier of the core yarn is, the larger the single-core difficulty is, and the higher the exposure probability of the stretch yarn core yarn is, so that the woven fabric is easy to have quality problems such as local elasticity loss or slipping and the like.

For the double-core-wrapping yarn, the composite yarn with the short fiber as the sheath and the two long fibers (at least one is an elastic yarn) as the core yarn is used for weaving the fabric, although the fabric has good elastic elongation and elastic recovery rate and can reduce the probability of the fabric slipping and bouncing to a certain extent, the fabric still has the problems of high shrinkage rate, high growth rate and small fabric finished product width, so that the fabric is easy to deform at certain positions with large stress, the wearing comfort and the effect of clothes are seriously influenced, meanwhile, when the fabric is perforated (when the fabric is perforated, namely the warp yarn of the fabric is damaged, the warp yarn in the perforated hole is removed, and the weft yarn is exposed), the weft yarn of the high-elasticity double-core-wrapping yarn can be curled at the perforated position, the weft yarn and the yarn of the weft yarn can be twisted together due to washing friction, and the appearance of the high-elasticity jean perforated hole is seriously influenced.

Thus, there is still a need for improvement and development of the prior art.
