Embodiment 1

[0016] Utilize the dyeing and finishing process of bamboo vinegar liquid, comprise the following steps:

[0017] ① Cooking and bleaching: place the bamboo fiber fabric in a boiling solution with a temperature of 95°C for 45 minutes. The boiling solution consists of 9g / L sodium carbonate, 4 g / L disodium NaOH, 14g / L hydrogen peroxide and water;

[0018] ② Dyeing: Cool the above bleaching solution to 55°C, add reactive dyes to make a dye solution, soak the bamboo fiber fabric with the dye solution for 15 minutes, add 45 g per 1 L of the dye solution, and add sodium sulfate after 10 minutes. Add soda ash in an amount of 10 g per 1 L of dye liquor, heat the temperature of the dye liquor to 90°C after 30 minutes and keep it for 15 minutes, pick out the dyed bamboo fiber fabric from the dye liquor, when the bamboo fiber fabric is cooled to 55°C Clean this bamboo fiber fabric with clear water, in dyeing process, bath ratio control is 1:9, and the reactive dyestuff content in the dye ...

Abstract

The invention relates to a process for dyeing and finishing by using bamboo vinegar, belonging to the technical field of textile dyeing and finishing. The process for dyeing and finishing by using bamboo vinegar comprises the following steps of: (1) boiling and blenching; (2) dyeing; and (3) after finishing. The after finishing specifically comprises the steps of: adding 18-22 grams of bamboo vinegar in each liter of water to make finishing liquor; carrying out after finishing on a bamboo fiber fabric by using the finishing liquor; and controlling the liquid entrainment rate of the bamboo fiber within 68-80%, the pre-drying temperature within 75-85DEG C and the curing temperature within 115-130DEG C during the after finishing. Compared with the prior art, the process of the invention is more suitable for dyeing and finishing the bamboo fiber; the bamboo fiber fabric dyed and finished by the process of the invention has favorable bacteriostasis rate and bacteriostasis value; and the physical properties such as air permeability, diffusivity, capillary effect and the like, which have larger influences on the bamboo fiber fabric, are improved obviously.

Description

technical field [0001] The invention relates to a dyeing and finishing process using bamboo vinegar, belonging to the technical field of textile dyeing and finishing. Background technique [0002] Due to the particularity of bamboo fiber, if the dyeing and finishing process of cotton textiles is continued, the natural antibacterial properties of bamboo fiber will drop sharply. According to relevant reports, the antibacterial rate of bamboo fiber blended fabrics after pretreatment and dyeing has been less than 70%, and the antibacterial value is less than 1. Not only that, the physical properties of bamboo fiber fabrics also changed greatly after the traditional fabric antibacterial finishing agent treatment, such as the air permeability and wool effect of the fabric decreased significantly, the fabric shade changed, etc., and the traditional finishing agent treatment High-quality fabrics have a certain stimulating effect on the skin, and the fabrics will gradually release h...
