Embodiment 1
[0013] A kind of same-color dyeing process of blended fabric, described blended fabric is the blended fabric of bamboo fiber, modal and wool, and described dyeing process comprises the steps:
[0014] 1) Reductive bleaching of the above-mentioned blended fabric;
[0015] 2) Dyeing the reduction bleached blended fabric with vinyl sulfone type reactive dyes;
[0016] 3) After washing and soaping, a blended fabric of the same color can be obtained.
[0017] The reduction bleaching process includes using 3 g / L of sodium hydrosulfite as a bleaching agent, and 1 g / L of sodiumpyrophosphate as a stabilizer; the bleaching temperature is 85° C.; and the bleaching time is 0.5 h.
[0018] The dyeing process is to first add 0.4g / L of Pingpingjia O, 5% (o.w.f) of vinyl sulfone type reactive dyes, and 30g / L of Yuanming powder to the dye bath, and then raise the temperature to 75°C at 1°C / min. Add soda ash 3g / L, dye for 1h.
Embodiment 2
[0020] A kind of same-color dyeing process of blended fabric, described blended fabric is the blended fabric of bamboo fiber, modal and wool, and described dyeing process comprises the steps:
[0021] 1) Reductive bleaching of the above-mentioned blended fabric;
[0022] 2) Dyeing the reduction bleached blended fabric with vinyl sulfone type reactive dyes;
[0023] 3) After washing and soaping, a blended fabric of the same color can be obtained.
[0024] The reduction bleaching process includes using 5 g / L of sodium hydrosulfite as a bleaching agent, and 1.5 g / L of sodium pyrophosphate as a stabilizer; the bleaching temperature is 95° C.; and the bleaching time is 0.5 h.
[0025] The dyeing process is to first add Pingpingjia O0.6g / L, vinyl sulfone type reactive dye 7% (o.w.f), and Yuanming powder 40g / L to the dye bath, and then heat up to 85°C at 1.5°C / min. Add 5g / L of soda ash and dye for 1h.

Abstract
The present invention discloses a same color dyeing process of a blended fabric. The same color dyeing process is characterized in that the blended fabric is a bamboo fiber, modal and wool blended fabric, and the dyeing process comprises: 1) carrying out a reduction bleaching treatment on the blended fabric; 2) dyeing the treated fabric with a vinyl sulfone type reactive dye; and 3) carrying out water washing and soaping to obtain the same color blended fabric. According to the present invention, the three different fibers are concurrently dyes through the process, the similar color can be obtained, the traditional same color dyeing process is shortened, and the processing cost is reduced.
Description
technical field [0001] The invention relates to a dyeing process of blended fabrics, in particular to a same-color dyeing process of blended fabrics made of bamboo fiber, modal and wool. Background technique [0002] The blended fabrics of different fibers need to make each component obtain basically the same color and reduce the color difference. Usually, dyed yarns of the same color are dyed separately, and then blended to obtain blended fabrics with good color properties; The method of secondary dyeing can obtain the blended fabric with good color property. No matter which of the above methods is adopted, the production process will be very complicated and the production cost will be high. Contents of the invention [0003] The object of the present invention is to provide a same-color dyeing process for blended fabrics. The dyeing process enables three different fibers to be dyed simultaneously to obtain relatively similar colors, shortens the traditional same-color d...
