Problems solved by technology

[0002] The existing high-shrinkage silk fabric production process is still immature, and color difference and color spots often appear on the surface of the fabric, so it is necessary to improve the dyeing process
[0003] In addition, the hand feeling of existing high-shrinkage silk fabrics is generally soft and smooth, which cannot provide the effect of imitating linen and cotton, and cannot present a grainy feel on the cloth surface, which needs to be improved

Embodiment 1

[0017] A method for dyeing and finishing a hemp-cotton-like high-shrinkage silk fabric, comprising the following steps:

[0018] Pre-treatment: put the fabric into the dye vat for the first heating treatment, add 4 g / L soda ash and 3 g / L emulsified degreaser when the temperature rises to 35°C, control the bath ratio at 1:8, and then continue For the second heating treatment, the temperature is controlled to 100°C, and the holding time is 30 minutes;

[0019] Pickling: After the pretreatment is finished, carry out cooling treatment. The cooling rate is controlled at 2°C / min. When the temperature drops to 45°C, drain the water in the dyeing vat and wash it twice, refill the water and add 2 g / L glacial acetic acid, and Carry out the third heating treatment, when the temperature rises to 50°C, wash the cloth for 15 minutes;

[0020] Dyeing: Add dye solution and auxiliaries at room temperature. The amount of dye in the dye solution depends on each color. Auxiliaries include: 98% c...

Embodiment 2

[0023] A method for dyeing and finishing a hemp-cotton-like high-shrinkage silk fabric, comprising the following steps:

[0024] Pre-treatment: put the fabric into the dyeing vat for the first heating treatment, add 5 g / L soda ash and 4 g / L emulsified degreasing agent when the temperature rises to 35°C, control the bath ratio at 1:12 and continue to the first step Second heating treatment, the temperature is controlled to 120°C, and the holding time is 50 minutes;

[0025] Pickling: After the pretreatment is finished, carry out cooling treatment. The cooling rate is controlled at 3°C / min. When the temperature drops to 46°C, drain the water in the dyeing vat and wash it twice, refill the water and add 3 g / L glacial acetic acid, and Carry out the third heating treatment, when the temperature rises to 50°C, wash the cloth for 30 minutes;

[0026] Dyeing: Add dye solution and auxiliaries at room temperature. The amount of dye in the dye solution depends on each color. Auxiliaries...

Abstract

The invention discloses a dyeing and finishing method for high-shrinkage silk fabrics imitating hemp and cotton. Through the above method, the dyeing and finishing method of the high-shrinkage silk fabric of imitating linen and cotton of the present invention uses pretreatment and acid washing to clean the fabric before dyeing, which is convenient for coloring and reduces the color difference and color pattern after dyeing. , During the dyeing process, the fabric fibers are opened and cooled to shrink, resulting in a unique product style. The fabric feels more like linen-cotton effect, the cloth surface is grainy, and the finished fabric is more like a woven fabric.

Description

technical field [0001] The invention relates to the field of dyeing and finishing of high-shrinkage silk fabrics, in particular to a dyeing and finishing method of high-shrinkage silk fabrics imitating hemp cotton. Background technique [0002] The existing high-shrinkage silk fabric production process is still immature, and color difference and color spots often appear on the surface of the fabric, so the dyeing process needs to be improved. [0003] In addition, the hand feeling of the existing high-shrinkage silk fabrics is generally soft and smooth, which cannot provide the effect of imitating linen and cotton, and cannot present a grainy feeling on the surface of the fabric, which needs to be improved. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a dyeing and finishing method of high-shrinkage silk fabric imitating linen cotton, which can provide the texture of imitating linen cotton and avoid color diff...
