Embodiment 1

[0014] A kind of dark color dyeing process of polylactic acid / Lisai / bamboo fiber blended fabric, its technological process is:

[0015] Desizing before dyeing → Enzyme treatment → Polylactic acid dyeing in the first bath → Reduction cleaning → Dyeing Lisa / bamboo fiber in the second bath → Soaping after dyeing.

[0016] The process of dyeing polylactic acid in the first bath is as follows: use disperse dye Disperse Yellow 3GE, dyeing temperature is 90°C, dyeing time is 60min, pH3, liquor ratio 1:30, leveling agent 1g / L, take out the fabric, first reduce and wash, then Wash again, dry;

[0017] The process of dyeing Lisai / bamboo fiber in the second bath is as follows: reactive red MZ-HW (o.w.f.) 2%, Pingping plus O1g / L, bath ratio 1:30, Yuanming powder 30g / L, sodium carbonate 20g / L, The dyeing temperature is 90°C, the dyeing time is 20 minutes, then washed with water, soaped, and dried;

Embodiment 2

[0019] A kind of dark color dyeing process of polylactic acid / Lisai / bamboo fiber blended fabric, its technological process is:

[0020] Desizing before dyeing → Enzyme treatment → Polylactic acid dyeing in the first bath → Reduction cleaning → Dyeing Lisa / bamboo fiber in the second bath → Soaping after dyeing.

[0021] The process of dyeing polylactic acid in the first bath is as follows: use disperse dye Disperse Blue S-3BG, dyeing temperature is 100°C, dyeing time is 40min, pH5, bath ratio 1:30, leveling agent 1g / L, take out the fabric, and first restore and clean , then washed with water and dried;

[0022] The process of dyeing Lisai / bamboo fiber in the second bath is: reactive blue MZ-RR (o.w.f.) 4%, flattened O1g / L, liquor ratio 1:30, sodium carbonate 30g / L, sodium carbonate 20g / L, The dyeing temperature is 80°C, the dyeing time is 100min, then washed with water, soaped and dried;

Embodiment 3

[0024] A kind of dark color dyeing process of polylactic acid / Lisai / bamboo fiber blended fabric, its technological process is:

[0025] Desizing before dyeing → Enzyme treatment → Polylactic acid dyeing in the first bath → Reduction cleaning → Dyeing Lisa / bamboo fiber in the second bath → Soaping after dyeing.

[0026] The process of dyeing polylactic acid in the first bath is: using disperse dyeing disperse red 3B, the material dyeing temperature is 110°C, the dyeing time is 30min, pH6, liquor ratio 1:30, leveling agent 1g / L, take out the fabric, first reduce and wash, Then wash with water and dry;

[0027] The process of dyeing Lisai / bamboo fiber in the second bath is: reactive black MZ-RR (o.w.f.) 5%, Pingping plus O1g / L, bath ratio 1:30, Yuanming powder 30g / L, sodium carbonate 20g / L, The dyeing temperature is 60°C, the dyeing time is 120min, then washed with water, soaped and dried;

Abstract

The invention relates to a polylactic acid / Richcel / bamboo fiber blended fabric dark color dyeing process with the steps of pre-dyeing de-sizing, enzyme treatment, first bath polylactic acid dyeing, reduction washing, second bath Richcel / bamboo fiber overdyeing, and post-dyeing soap boiling. The process has the advantages that: two dyes can be used for dyeing under respective appropriate process conditions, such that excellent color degree of dyeing and fastnesses can be respectively obtained. Active dye is used after disperse dye. The high-temperature weak-acidity dyeing conditions of the disperse dye do not affect the covalent bond fastness between active dye and cotton fiber. The process is a novel preferable process for polylactic acid / Richcel / bamboo fiber blended fabric dark color dyeing. With the process, dye utilization rate can be improved, and color fixing rate can be improved.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to a dark color dyeing process of polylactic acid / Liesel / bamboo fiber blended fabrics. Background technique [0002] Polylactic acid fiber belongs to polyester fiber. Polyester fiber is generally dyed with disperse dyes, while cotton fiber can be dyed with reactive, direct, and vat dyes. Therefore, polylactic acid blended fabrics can be dyed with disperse / reactive dyes, disperse / direct dyes, and disperse dyes. / Dyeing process such as vat dyes. [0003] There are many factors that affect the dyeing of polylactic acid fibers, such as polylactic acid fibers are not resistant to high temperature, strong acid, strong alkali, and easy to hydrolyze. There are still many problems to be solved in the dyeing of polylactic acid fibers. Although the reflection coefficient of polylactic acid fibers is smaller than that of other fibers, it is difficult to dye da...
