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 an active dye union dyeing method of a silk / non-shrinkable (mercerized) wool interwoven fabric. The method comprises the steps of dyeing and soaping: (1) dyeing: taking the silk / non-shrinkable (mercerized) wool interwoven fabric; performing dyeing respectively by using 1 to 6 percent of active dye under the conditions of union levelling agents R being 0.5 to 1.5 g / L, anhydrous sodium sulphate being 60 to 70 g / L and bath ratio being 1:50 at the temperature being 60 to 70 DEG C for 85 min; (2) soaping: after the dyeing, performing soaping for 15 min at 90 DEG C accordingto the formula of 1 g / L soap flakes and 1 g / L sodium carbonate, wherein the bath ratio is 30:1. The method overcomes the problem of poor color fastness of the acid dye; the union dyeing can be realized; the dyeing process is simple; the dyeing is convenient; the cost is low.

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...
