Problems solved by technology

[0003] Cotton fluorescent fabrics are woven from cotton fluorescent yarns, but in the spinning process of cotton fluorescent yarns, there are problems such as poor dyeing permeability of cheese yarns, easy to be caught, etc., and there are differences in the compatibility of reactive dyes and fluorescent dyes. , it is easy to cause problems such as out-of-sync coloring and color flowering, as well as fluorescence quenching in the production process

Embodiment Construction

[0012] The present invention will be described in further detail below through specific examples, but the present invention is not limited to these examples.

[0013] A dyeing process of cotton fluorescent yarn, the process includes winding→bleaching→dyeing. In the winding process, a fully automatic loose winder is used to wind the yarn into conical or cylindrical bobbins. The yarn density is 0.38g / cm 2 , the package size is 300~450g;

[0014] Yarn re-bleaching technology is adopted in the bleaching process: for the first bleaching, the cheese is placed in a solution with a multi-effect refining agent concentration of 3-5g / L and a temperature of 100°C for 60 minutes; for the second bleaching, the cheese is Place it in a solution containing hydrogen peroxide and multi-effect refining agent at a temperature of 100°C for 60 minutes. The concentration of multi-effect refining agent is 3-5g / L, and the concentration of hydrogen peroxide is 3-8g / L;

[0015] In the dyeing process, c...

Abstract

The invention discloses a dyeing process for all-cotton fluorescent yarns. The process comprises the steps of winding, bleaching and dyeing. A dyeing solution uniformly penetrates through the yarns by reducing the density and the size of cheeses so as to reduce the chromatic aberration; by virtue of two times of bleaching, the whiteness of the yarns is improved; a fluorescent active dye and a common active dye are compounded according to a certain ratio and are used for dyeing the yarns and the ratio is determined according to required dyeing so as to guarantee that one-time dyed rate of dyeing is more than 90% and the dyeing defect is reduced to 2%; a weakly cationic softening agent is added into the dyeing solution; after dyeing is finished, a full-automatic rotary table is used for dehydrating so as to guarantee cheese molding and reduce a rewinding procedure, and furthermore, the fluorescent loss of the yarns is reduced.

Description

technical field [0001] The invention relates to the field of yarn dyeing technology, in particular to a dyeing technology of cotton fluorescent yarn. Background technique [0002] Cotton fluorescent fabric has bright color, good gloss, even and delicate surface, and excellent comfort performance. It integrates color and function. Clothes made of cotton fluorescent fabric are cool, comfortable and unique in style. It is the first choice for high-end summer clothing. [0003] Cotton fluorescent fabrics are woven from cotton fluorescent yarns, but in the spinning process of cotton fluorescent yarns, there are problems such as poor dyeing permeability of cheese yarns, easy to be caught, etc., and there are differences in the compatibility of reactive dyes and fluorescent dyes. , It is easy to cause problems such as out-of-sync coloring and color flowering, as well as fluorescence quenching in the production process. Contents of the invention [0004] In order to solve the abo...
