Yarns with non-uniform fiber distribution, fabric and preparation method thereof

Abstract

The invention discloses yarns with non-uniform fiber distribution, a fabric and a preparation method thereof. The preparation method of the yarns with non-uniform fiber distribution comprises the following steps of: (1) first opening and mixing: arranging polyester fibers and cellulose fibers on a bale plucker not uniformly, and opening and mixing the fibers; (2) first carding: carding the fibersprepared in the step (1) to obtain first carded slivers; (3) second opening and mixing: arranging natural fibers in the bale plucker, and opening and mixing the fibers; (4) second carding: carding the fibers prepared in the step (3) to obtain second carded slivers; (5) drawing: arranging the first carded slivers and the second carded slivers on an elevated platform of a drawing frame not uniformly, and drawing the carded slivers; (6) roving; (7) spinning; and (8) spooling. The surface color textures of the fabric woven by adopting the yarns are arranged transversely and non-uniformly, and thewhole fabric is very attractive.

Description

technical field [0001] The invention relates to a yarn with uneven fiber distribution and its preparation method, a fabric with uneven fiber distribution and its preparation method. Background technique [0002] The commonly used dip-dyeing and pad-dyeing of fabrics can only form a uniform color, but cannot form a specific uneven color texture on the surface of the fabric. [0003] Printing and dyeing and yarn-dyed methods are usually used to solve the color texture of the fabric surface. [0004] The printing and dyeing method usually adopts the screen printing and dyeing method, and the printing and dyeing slurry is evenly coated on the surface of the fabric. Different color textures are completed through multiple printing and dyeing. Although the printing and dyeing method can design and produce uneven color textures, due to the material and coating thickness of the printing and dyeing slurry, it is easy to form a coating layer on the surface of the fabric and harden th...

AI Technical Summary

Problems solved by technology

Although the dyed weaving method solves the defect of fabric surface hardening caused by printing and dyeing, it is suitable for weaving yarns of different colors with large contrast to form colored fabrics, and the color of the woven fabric has the defect of rough surface texture and not delicate, especially cannot A pattern that handles the blooming effect of colors in the same base color

[0006] In addition, the batik method can also be used to print and dye fabrics with uneven colors, but the batik method can only form large color blocks, the texture is not delicate, and the process steps are complicated and difficult to control, so it is not suitable for large-scale continuous production

[0007] There is also a kind of fabric that uses colored slub yarn to weave uneven colors. In addition to the defect that the surface texture of yarn-dyed fabrics is rough and not fine, it loses the flatness of the fabric while forming uneven colors.
