Embodiment 1

[0027] A processing method of 60S / 2 gray bottom camouflage blue-violet yarn, comprising the following processing steps:

[0028] 1. Raw yarn preparation

[0029] Choose 60S / 2 high-quality cotton yarn.

[0030] 2. Dyeing

[0031] The base color is gray dyed on the domestic hank dyeing machine, and the uniform dyeing is ensured by controlling the amount of dye, saline and alkali, and color fixing time. The concentration is 0.5%-1% (owf), the amount of salt: 20g / L-30g / L, the amount of alkali 10g / L-20g / L, and the time is 45min.

[0032] 3. Spray dyeing, adopting the spray dyeing process of continuous spot spraying

[0033] Put the yarn flat on the dyeing machine table, add blue to the left nozzle of the first row of nozzles, add purple to the two nozzles on the right, control the speed at 0.99m / min~5m / min, Add water to the second row of nozzles, control the vehicle speed at 0.99m / min~5m / min, bloom the original blue and purple dyes, and form a blue-purple pattern with denser bl...

Embodiment 2

[0042] A kind of processing method of 60S / 2 blue ground camouflage navy blue yarn, comprises following processing steps:

[0043] 1. Raw yarn preparation

[0044] Choose 60S / 2 high-quality cotton yarn.

[0045] 2. Dyeing

[0046] The base color blue is dyed on the domestic skein dyeing machine, and the uniform dyeing is ensured by controlling the amount of dye, saline and alkali, and color fixing time. The concentration is 0.5%-1% (owf), the amount of salt: 20g / L-30g / L, the amount of alkali 10g / L-20g / L, and the time is 45min.

[0047] 3. Spray dyeing, adopting the mist jet dyeing process of intermittent spot spraying

[0048] Put the yarn flat on the dyeing machine workbench, perpendicular to the forward direction, spray the dye intermittently, control the liquid volume at 0.1-2ml / time, spray navy blue dye on one of the nozzles on the first row of nozzles, A small amount of scattered navy blue is formed on the surface of the skein, and finally a small amount of uneven blue...

Embodiment 3

[0057] A kind of processing method of camouflage red yarn of 70S / 2 white background, comprises following processing steps:

[0058] 1. Raw yarn preparation

[0059] Choose 70S / 2 high-quality cotton yarn.

[0060] 2. Spray dyeing, spray dyeing process using the spray method at the top of the nozzle

[0061] Put the yarn flat on the dyeing machine table, spray red dye on one of the nozzles in the first row, because the dye spreads upwards, similar to the principle of a fountain, when it falls on the surface of the yarn, it is in the form of mist Scattered, the vehicle speed is controlled at 0.99m / min to 5m / min, forming a camouflage red pattern on a white background.

[0062] 3. Steam

[0063] The spray-dyed yarn is steamed in a steam box at a temperature of 100° C. to 110° C. for 10 minutes to 20 minutes.

[0064] 4. Washing

[0065] 5. Dehydration and drying

[0066] The above-mentioned yarns are put into a rotary drying room for drying, and the yarns are dried at a low t...

Abstract

The invention relates to a camouflage color yarn production method which comprises the following steps: raw yarn preparation, spray dying, decatizing and color fixing, soaping, drying and barrel inverting; the spay dying is characterized in that dyes are sprayed in a fog way; the yarns are flatly laid on a workbench of a continuous dying device in a yarn twisting way, a spray head leaves a distance from the yarns, and the dyes are sprayed onto the yarn surfaces. A dying step can be added between the raw yarn preparation step and the spray dying step. The invention adopts the spray dying technology, the spray head leaves a certain distance from the yarns to spray dyes, the dyes form a fog shape and are scattered onto the yarn surfaces, the yarn distribution is irregular, the color length is unequal, and the yarns are distributed in a mesh way, so the yarns can show a camouflage style. The invention adds the dying step between the raw yarn preparation step and the spray dying step, the yarns are dyed with bottom color, and the yarn is in a style of irregular camouflage characteristic.

Description

technical field [0001] The invention relates to a production method of dyed yarn, in particular to a production method of camouflage color yarn. Background technique [0002] Yarn dyeing generally requires uniform dyeing, so the method of fully soaking the yarn with the dye is used to make the yarn even in color. However, as modern people pursue individual requirements, it is particularly important to develop yarns that are more novel and colorful, while traditional dyeing methods cannot meet market demand. Contents of the invention [0003] Aiming at the above phenomenon, the present invention provides a production method of camouflage colored yarn. The colored yarn produced by the method not only has the advantage of rich colors, but also the color distribution on the yarn is completely irregular, so that the yarn shows the appearance of camouflage. style, suitable for more occasions. [0004] The technical scheme of the present invention is as follows: the producti...
