Preparation method for easily-printed wool yarn

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 ...

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 after there is a layer of scales on the surface of the wool fiber. Molecules are less likely to enter the interior of the fiber, which will cause a layer of white hair on the surface of the woolen sweater after printing, which is very unsightly
