Production method of ultra-black wool worsted fabric

Abstract

The invention discloses a production method of ultra-black wool worsted fabric. According to the method, wool tops after wool mercerizing shrink-proof treatment are selected as raw materials, and theraw materials are successively subjected to dyeing, back washing, secondary dyeing, sliver mixing, carding, combing, re-combing, roving, spun yarns, cabling tube, yarn steaming, weaving, wet finishing, dry finishing and functional colour-increased finishing to prepare finished products. Wool and polyester fibers are all treated with secondary dyeing to increase the color thickness after dyeing, and auxiliaries are used for processing to increase blackness and color depth of the fabric; secondly, wool fibers and the polyester fibers are subjected to the back washing after top dyeing, secondarydyeing is conducted again, and dye-uptake of dye and the color depth are further increased; meanwhile warps and wefts of the fabric are made by the secondarily dyed wool which is treated with the re-combing and spinning later, so that the color depth and apparent depth of the black worsted fabric produced are greatly deepened; finally, an intensifier deep agent and a penetrating agent are used forfurther processing in a soft padding groove during a finishing process, thereby further improving the dyeing depth of the wool fabric.

Description

technical field [0001] The invention relates to the technical field of wool worsted fabrics, in particular to a production method of ultra-black wool worsted fabrics. Background technique [0002] For formal occasions, black dresses are the choice of most people. In Southeast Asia, Europe and the United States, every adult has a black dress. As an eternal classic color, black has long been an important part of dress fabric colors and has a good sales market. As a natural fiber, wool is very popular among consumers because of its soft feel, firm texture, good curl elasticity and warmth retention, and natural and soft luster. Because there is a certain limit in the absorption performance of the fiber to the dye and the dyeing rate of the dye on the fiber, that is, the dyeing depth of the fiber is not infinite. When the dye reaches a certain amount, the dyeing depth of the fiber reaches the limit. At this time, if the amount of dye is increased, the dyeing depth will no long...

Problems solved by technology

At this time, if the amount of dye is increased, the dyeing depth will no longer increase, but the floating color will increase and the color fastness will decrease.
