Description
Technical field
The present invention relates to a kind of spandex/silk crepe ground knitted fabric and preparation method thereof, particularly a kind of employing spandex/real silk cladding yarn knitted fabric is organized knit product and the processing method of creasing with forming crape.
Background technology
Crape ground style fabric panel is silk and the cotton emphasis of product development of knitting always, the principal character of crape local specialties is " crape effects ", in addition, the crape local specialties also have quality softness, frivolous, high resilience, active characteristics such as natural, various informative, are subjected to consumer's favor.Fabric crepe/draw process is a lot, and the one, reach the crape effect of weaving face fabric by raw material, yarn, fabric tissue; The 2nd, by finishing process in printing and dye-ing, make the weaving face fabric surface produce crape effect with method chemical, physical mechanical.At present, method commonly used has: (1) fabric and hard twist: produce wrinkle by the combination and the twist that changes through weft yarn, as the crepe de Chine and the Qiao Qi of silk fabrics.(2) different shrinkage factor yarn: utilize the different shrinkage factors of fiber, the institutional framework design through suitable forms wrinkle.(3) stripped crepe: with the tight twist yarn is the fabric of parallel, by the loose processing of printing and dyeing, produces the shrinkage of warp-wise.(4) MIXED FABRIC: with synthetic fiber yarn and yarn interweaving, during by loose handle the contraction of fiber poor, produce concave-convex sense.(5) fabric tissue changes: utilize crape tissue, concavo-convex tissue, design through the long different institutional framework of fill yarns float, the style of tree bark is arranged; (6) other class: as the processing of seersucker, ripple, roll that strand processing, cotton ginning processing, rivel processing, High Temperature High Pressure are creased, the alkali contraction is creased etc.The above-mentioned method that makes fabric have wrinkling effect is not suitable for processing the silk like lining with coil crape ground tissue.
Contain the spring function of paying attention to fiber in the exploitation of spandex fibre lining, because of the heat resistance of spandex fibre relatively poor, particularly damp and hot performance is poorer, add man-hour in printing and dyeing, generally to prevent heat (xeothermic or damp and hot) processing to the flexible loss of spandex fibre, to keep the high elasticity and the high recovery of spandex fibre.Therefore, the main purpose of sneaking into spandex in real silk, cotton fiber is to improve the elasticity of fabric.
At present, the silk crepe kind fabric that contains spandex in exploitation is still continued to use original real silk crepe de Chine or tall its weaving process, and raw material adopts real silk/spandex cladding silk, mostly be looping type structure, promptly be heart yarn with the spandex, outer looping cocoon fiber, real silk is the arrangement of looping type at the skin of spandex heart yarn.Crape ground tissue is that twisting difference (as twisting and not twisting), twist difference (heavy twist and weak twist), the sth. made by twisting by yarn realized to difference (left-hand lay and right-laid).Printing and dyeing add man-hour, because of the heat-shrinkable of spandex bigger, particularly the hydrothermal stability of spandex is relatively poor, cause the elastic loss and the recovery variation of spandex fibre when temperature is high easily, therefore, one of emphasis of printing and dyeing processing is that the elasticity that guarantees original spandex is not subjected to or suffers a loss less, as the lower shrinkage factor of control, lower damp and hot or dry heat treatment condition etc.Like this, though elasticity is better in use for lining or clothes, the morphotropism of lining is bigger, and contraction distortion is bigger, and particularly washing back morphotropism is bigger, directly has influence on wearability and appearance property.This is because raw material selects for use real silk/spandex looping type yarn to cause.As adopt paracytic type real silk/spandex cladding silk, and promptly be heart yarn with the spandex, outer looping cocoon fiber, real silk almost are at the skin of spandex heart yarn and are arranged in parallel, and the twist of promptly outer real silk on the sandwich layer spandex is less, and real silk and spandex are similar to and are arranged in parallel.Yarn is easy to make naked spandex yarn to expose after twisting, directly influences coloration of textile materials uniformity and COLOR FASTNESS, and the spandex silk ruptures easily, directly has influence on the wearability of fabric.
