Embodiment 1

[0025] The fabric is silk / preshrunk wool (mercerized) blended fabric (silk 40%, wool 60%). Respectively dye with 1% reactive dyes such as reactive red 3BS in the same color leveling agent R 0.5g / L, Yuanming powder 60g / L, bath ratio 1:50, dyeing in total for 85min. Heating curve such as figure 1 shown;

[0026] Soaping process: both soap flakes and sodium carbonate are 1g / L, liquor ratio 1:50, soaping at 90°C for 15 minutes, washing with water, and drying.

Abstract

The invention discloses a method for same-color dyeing of a silk / shrinkproof (mercerized) wool interwoven fabric with reactive dyes, which includes a dyeing step and a soaping step: (1) Dyeing: take the silk / shrinkproof wool (mercerized) interwoven fabric, and use 1 ~6% reactive dyes are dyed under the conditions of the same color leveling agent R 0.5~1.5g / L, sodium phosphate 60~70g / L, bath ratio 1:50, the temperature is 60~70°C, and the time is 85min; (2) Soaping: soaping after dyeing, the soaping formula is: soap flakes 1g / L, sodium carbonate 1g / L, liquor ratio 30:1, soaping at 90°C for 15 minutes. The invention overcomes the problem of poor color fastness of acid dyes, can achieve the same color dyeing, has simple dyeing process, convenient dyeing and low cost.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and relates to a method for same-color dyeing of real silk / shrinkproof (mercerized) wool interwoven fabrics with reactive dyes. Background technique [0002] Silk is a natural protein fiber, known as the "Fiber Queen". It not only has a soft and elegant appearance, but also has the inner quality of skin care and health care. Shrink-resistant wool has the advantages of soft hand feeling, non-itching feeling and anti-pilling, etc., which has attracted widespread attention of consumers. [0003] Silk and shrink-proof wool interwoven fabric combines the excellent properties of both, making it have both the soft luster of silk and the excellent elasticity of wool, which can increase the elasticity, moisture absorption and warmth retention of silk fabrics, improve the performance of silk products, and broaden the application of silk products It can be used to develop high-grade su...
