Problems solved by technology

[0002] Since Tencel itself has a high degree of orientation and high crystallinity, and has high metafibrillation and transverse swelling in the wet process, so Tencel (TENCEL) and cotton blended fabrics are prone to metafibrillation during the dyeing process. And problems such as poor fastness and not deep dyeing, especially black, it is difficult to achieve the ideal blackness
With the traditional process, energy is wasted (working hours, water, electricity, steam, dyes), not only the dark fabrics cannot meet the color requirements, but also the excessive use of dyes affects the fastness and increases the amount of sewage discharge, and also increases the production cycle. limited production

Embodiment 1

[0020] Put 50 kg of Tencel / cotton (40 / 60) 60 / 2s blended yarn into the dyeing bath prepared according to the bath ratio of 1:20 (o.w.f), run for 15 minutes at room temperature, add 2 kg of 808 detergent and 1 Kg of JFC penetrant, run at 90-100°C for 30 minutes, wash once with hot water at 50-60°C, and then wash twice with cold water;

[0021] Heat the above dye bath to 60°C at a rate of 1°C / min, add 4 kg of Cibacron black W-NN, run for 10 minutes, add 60-80 kg of sodium sulfate, run for 15 minutes, add 20 kg Soda ash and 3 kg of caustic soda, and then run for 50 minutes.

[0022] Wash the dyed Tencel-cotton blended fabric twice at 50-60°C, add 0.5 kg of acetic acid for the second time, and wash for 10 minutes each time, then add 2 kg of 808 detergent and heat up to Run at 90°C for 15 minutes, drain the residual liquid, wash with hot water at 50-60°C, add 2 kg of color-fixing agent F-ER and 2 kg of softener CT, and dry to obtain the dyed product.

Abstract

The invention discloses a shower multi-activity dyeing method of silk floss blending fabrics. According to the structure of silk molecule, it uses the cross-linking effect of multi-activity base dye to multi-reaction between silk fiber structure, it decreases the raw fiber rate, at the same time, it uses the caustic soda and soda ash as soda agent, the silk fiber and cotton fiber will properly swell, it is beneficial for dye to permeate into fiber, enhances the homogeneity, reappearing and color quantity of dyeing, the invention can dye silk floss blending fabrics on time.

Description

technical field [0001] The present invention relates to a kind of dyeing method of blended fabric, specifically relate to the dyeing method of TENCEL (TENCEL) and cotton blended fabric, more specifically relate to TENCEL (TENCEL) and cotton blended fabric one-bath multi-reactive group dye Mixed base staining method. Background technique [0002] Since Tencel itself has a high degree of orientation and high crystallinity, and has high metafibrillation and transverse swelling in the wet process, so Tencel (TENCEL) and cotton blended fabrics are prone to metafibrillation during the dyeing process. And problems such as poor fastness and not deep dyeing, especially black, it is difficult to achieve the ideal blackness. With the traditional process, energy is wasted (working hours, water, electricity, steam, dyes), not only the dark fabrics cannot meet the color requirements, but also the excessive use of dyes affects the fastness and increases the amount of sewage discharge, and...
