Problems solved by technology

When printing, the dye and the paste are mixed together and applied on the woolen sweater. The dye penetrates into the fiber by itself, which is more difficult than in the dye solution. The dye molecule is not easy to enter the fiber, especially

Example Embodiment

[0010] Example 1:

[0011] In the preparation method of wool easy-printable yarn described in this embodiment, in the first step, the surface of the yarn is loosened by the loose ball equipment; in the second step, the surface of the yarn is stripped with sodium hypochlorite; the third step, The yarn after the scale-stripping treatment is cleaned twice, and the chemical agent on the surface of the yarn is rinsed; the fourth step is to use a softener to soften the yarn; the fifth step is to dry the softened yarn Dry and roll.

[0012] The processing depth of the wool yarn is controlled at 1.2%. In the second step, the concentration of sodium hypochlorite is 0.3g / L, the PH value is controlled at 2, and the temperature is controlled at 10°C. In the third step, the cleaning temperature is controlled at 35°C. , The fifth step, the drying temperature is 110°C; the moisture regain of the yarn after the treatment is completed is controlled at 9%.

Example Embodiment

[0013] Example 2:

[0014] In the preparation method of wool easy-to-print yarn described in this embodiment, in the second step, the concentration of sodium hypochlorite is 0.3g / L, the PH value is controlled at 2.5, and the temperature is controlled at 12°C. In the third step, the cleaning temperature is controlled at 40 ℃, the fifth step, the drying temperature is 110℃; the moisture regain of the yarn after processing is controlled at 11%.

Abstract

The invention discloses a preparation method for an easily-printed wool yarn. The preparation method comprises the following steps of: 1, performing pinecone processing to the surface of the yarn by pinecone equipment; 2, performing scale-stripping processing to the surface of the yarn by sodium hypochlorite; 3, secondarily cleaning the yarn which is performed with the scale-stripping processing, and washing a chemical agent on the surface of the yarn; 4, performing softening processing to the yarn by a softening agent; and 5, drying and winding the yarn which is performed with the softening processing. By the preparation method for the easily-printed wool yarn, the scale-stripping processing is performed to the wool fibers, sodium hypochlorite is used as a scale-stripping agent, and after sodium hypochlorite is dissolved in water, hypochlorite reacts with the scales on the surface of the wool to enable the scales of the wool to be stripped and dissolved in water, so that a scale-stripping effect is realized, and when the printing is performed to the yarn, dye is easily penetrated into the yarn, and a dying effect is great.

Description

technical field [0001] The invention relates to the field of wool yarn preparation, in particular to a method for preparing wool easy-to-print yarn. Background technique [0002] In the past two years, there have been more and more styles of woolen sweater printing, and the printed patterns have become more and more complex. The more complex the patterns of woolen sweaters, the higher the requirements for the definition of the border of the pattern. A clear Sweaters with poor strength are inferior in grade and appearance. Generally speaking, when encountering this kind of situation, woolen sweater factories will carry out pre-processing during printing to solve this problem, but the clarity of the border of the pattern is solved, and the style of the woolen sweater has changed. Wool sweaters are easy to get hairy, and the surface of the sweater is not smooth. If the printed color is of high contrast, the place where the two colors with high contrast meet will stick to each ...
