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 w

preparation example Construction

[0071] A method for preparing a yarn with uneven fiber distribution, comprising the steps of:

[0072] (1) First opening and mixing

[0073] Make one pile of polyester fibers and another pile of cellulose fibers, and arrange the two piles of fibers on the plucking machine for opening and mixing;

[0074] The polyester fiber accounts for 30-60% by weight of the finished yarn, and the cellulose fiber accounts for 10-30% by weight of the finished yarn.

[0075] In the first opening and mixing step of the present invention, the plucking machine may be a disc plucking machine or an in-line plucking machine.

[0076] Taking the disc plucking machine as an example,

[0077] In the prior art, the arrangement and distribution of the raw materials of the disc bale machine in the opening and mixing step is as follows: figure 2 shown. The feeding of polyester fiber 1 and cellulose fiber 2 is evenly arranged in the disc catching machine, and the polyester fiber 1 and cellulose fiber 2...

Embodiment 1

[0116] A method for preparing a fabric with non-uniform fiber distribution, its process flow chart can be found in figure 1 . Specifically include the following steps:

[0117] (1) First opening and mixing

[0118] Make one pile of polyester fibers and another pile of cellulose fibers, and arrange the two piles of fibers on the plucking machine for opening and mixing;

[0119] The polyester fiber accounts for 30% by weight of the finished yarn, and the viscose fiber accounts for 10% by weight of the finished yarn.

[0120] The arrangement and distribution of the raw materials of the disc bale machine in the first opening and mixing step is as follows: image 3 shown. The feeding of polyester fiber 1 and cellulose fiber 2 in the disc catching machine is unevenly arranged, and the distribution of polyester fiber 1 and cellulose fiber 2 is unevenly distributed at large intervals. The rotating shaft 4 of the disc catching cotton machine rotates vertically, and at the same tim...

Embodiment 2

[0166] A method for preparing a fabric with non-uniform fiber distribution, its process flow chart can be found in figure 1 . Specifically include the following steps:

[0167] (1) First opening and mixing

[0168] The polyester fibers and cellulose fibers are arranged unevenly on the in-line plucking machine. The specific method is: the polyester fiber is one pile, the cellulose fiber is another pile, and the two piles of fibers are arranged on the cotton plucking machine. Then carry out loosening and mixing;

[0169] The polyester fiber accounts for 60% by weight of the finished yarn, and the viscose fiber accounts for 30% by weight of the finished yarn.

[0170] The arrangement and distribution of the raw materials of the in-line plucking machine are as follows: Figure 5 shown. The in-line plucking machine is unevenly arranged for the feeding of polyester fiber 1 and cellulose fiber 2, and the distribution of polyester fiber 1 and cellulose fiber 2 is uneven and large...

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...
