Problems solved by technology

However, due to the fiber opening process of polyester fabrics, it needs to be carried out under alkaline conditions, and when conventional dyes are dyed under high-temperature alkaline conditions, discoloration or colorlessness will occur; as a result, manufacturers currently need to After the fiber opening process, water washing and acid neutralization can be carried out before the dyeing process can be continued, resulting in a decrease in the dyeing and finishing efficiency of polyester brushed cloth and an increase in water and electricity consumption, low production efficiency and high production costs; and polyester brushed cloth A large amount of oligomers will also be produced during dyeing, which will cause problems such as color flowers and spots after dyeing, increase the difficulty of cleaning the pipelines of dyeing and finishing equipment, and reduce the dyeing effect of polyester brushed cloth
In addition, since the surface area of ​​superfine polyester fiber is much larger than that of ordinary polyester fiber, the adsorption speed of dyes is also much faster; the dyeing speed of polyester brushed cloth is also accelerated as the single filament fineness becomes thinner, resulting in a decrease in the initial dyeing rate. increase, which is not conducive to level dyeing, resulting in a decrease in the overall dyeing effect of polyester brushed fabrics
Therefore, the existing methods for dyeing polyester microfiber brushed cloth have the problems of low dyeing efficiency, high dyeing cost and poor dyeing effect

Abstract

The invention discloses a method for dyeing polyester ultrafine fiber brushed cloth. The method includes steps of placing the preset polyester ultrafine fiber brushed cloth in dyeing machines; addingsplitting dyeing one-bath dye liquor into the dyeing machines; heating the dye liquor at the speed of 2-3 DEG C / min from the room temperature to the temperature of 60 DEG C; further heating the dye liquor at the speed of 0.5-0.8 DEG C / min from the temperature of 60 DEG C to the temperature of 110 DEG C; soaking the polyester ultrafine fiber brushed cloth in the dye liquor for 10-20 minutes, and then heating the dye liquor at the speed of 0.8-1 DEG C / min until the temperature of the dye liquor reaches 130 DEG C; soaking the polyester ultrafine fiber brushed cloth in the dye liquor for 20-40 minutes, then cooling the dye liquor at the speed of 1.5 DEG C / min until the temperature of the dye liquor reaches 80 DEG C and then draining the liquor; carrying out reduction clearing and acid neutralization on piece goods in environments at the temperatures of 80 DEG C; cooling the piece goods until the temperatures of the piece goods reach the room temperature, and then sequentially dehydrating,setting and drying the piece goods. The method has the advantages of high dyeing efficiency, low dyeing cost and good dyeing effect.

Description

technical field [0001] The invention relates to a method for dyeing superfine fiber cloth, in particular to a method for dyeing polyester superfine fiber brushed cloth. Background technique [0002] After sand washing, sanding and other advanced finishing, the fabric made of microfiber can form a layer of peach skin fluff on the surface, and has the characteristics of fluffy, soft and smooth, so it is deeply loved by users. The polyester brushed cloth, especially the peach skin / coral fleece as a special product, is more widely used in various fields because of its cotton-like characteristics. However, due to the fiber opening process of polyester fabrics, it needs to be carried out under alkaline conditions, and when conventional dyes are dyed under high-temperature alkaline conditions, discoloration or colorlessness will occur; as a result, manufacturers currently need to After the fiber opening process, water washing and acid neutralization can be carried out before the d...
