Milk protein fiber or its filament or its blended fabric weaving and dyeing method

A milk protein fiber, blended fabric technology, applied in textiles and papermaking, textile material processing, fabrics, etc., can solve the problem of color uniformity and homochromaticity that affect brightness, saturation of dyeing, and cannot produce high blending ratios Milk protein fiber products cannot fully reflect the excellent properties of milk protein fiber and other problems, and achieve the effect of moderate shrinkage, low tightness and low density

Problems solved by technology

[0006] 2. When weaving blended yarns, a low proportion of milk protein fibers generally not exceeding 20% ​​is added to blend or interweave with natural fibers, regenerated cellulose fibers, synthetic fibers, etc., regardless of the dyeing of milk protein fibers; or milk protein Fiber stays white without dyeing
The disadvantages of this production process and production method are: it cannot produce high blending ratio and pure milk protein fiber products, and cannot fully reflect the excellent performance of milk protein fibers; Affect the various color fastness indicators of the product and the vividness of the color, the saturation of the dyeing, the uniformity of the color and the same color; the hand feel cannot be fully utilized, and the softness, drapability and elasticity of the fabric are very poor
However, no matter which dye is used for dyeing, even if a reasonable production process is selected, it is difficult for milk protein fiber to achieve uniform dyeing and good color fastness

Embodiment 1

[0036] The processing method for weaving and dyeing of milk protein fiber filament and its doubling, twisting, core-spun yarn and its short fiber and cotton blended fabric is as follows:

[0037] Step 1: Weaving

[0038] a. Weaving by large circular knitting machine or circular knitting machine trolley: gray yarn - rewinding - waxing - knitting frame -

[0039] Weaving—semi-finished product inspection—cloth repair—cloth inspection;

[0040] b. Weaving with shuttle and non-shuttle looms: gray yarn - warping - sizing - loom on the weaving shaft

[0041] - weaving - semi-finished product inspection - cloth repair - inspection

[0042] Cloth - matching cylinder;

[0043] Among them: when weaving, compared with conventional products, it is necessary to relax the fabric tightness by 25%;

[0044] Step 2: Dyeing

[0045] a. Put milk protein fiber or its filament or its blended fabric with cotton ...

Embodiment 2

[0055] Milk protein fiber filaments and their milk protein fiber yarns blended or plied with natural or regenerated cellulose fibers, yarns covered with filaments such as spandex, nylon, XLA, PTT, etc., or gray fabrics embedded with these filaments during weaving The methods of weaving and dyeing are:

[0056] Step 1: Weaving

[0057] Weaving by warp knitting machine: gray yarn - warping - knitting frame on the weaving beam - weaving - half

[0058] Finished product inspection - cloth repair - cloth inspection - cylinder matching;

[0059] Weaving by weft knitting machine: gray yarn—reversing cylinder—waxing—knitting frame on circular machine—weaving

[0060] Manufacture—semi-finished product inspection—cloth repair—cloth inspection—cylinder matching;

[0061] Among them, when weaving, it is necessary to relax the fabric tightness to 30%;

[0062] Step 2: Dyeing

[0063] The special auxiliary agent for dyeing milk protein fiber is u...

Embodiment 3

[0065] Wool, rabbit fur, cashmere, silk, milk protein fiber, soybean protein fiber and other animal and vegetable protein fibers and their blended yarns covered with spandex, nylon, XLA, PTT filament yarn or gray cloth embedded with these filaments during weaving and coloring:

[0066] Step 1: Weaving

[0067] Weaving process is the same as example 1;

[0068] Among them: when weaving, it is necessary to relax the fabric tightness to 25%;

[0069] Step 2: Dyeing

[0070] The dyeing process is the same as in Example 1, but it is necessary to use traditional acid dyes to dye natural protein fibers. After removing the floating color, the milk protein fibers are over-dyeed with reactive dyes to ensure the uniformity of dyeing fastness, vividness and color. , the hydrogen peroxide stabilizer is CAN.
