Problems solved by technology

When dyeing and processing real silk two-component fabrics, in order to obtain products with good homochromaticity, two dyes are usually used for one-bath two-step dyeing or two dyes for two-bath dyeing. The production process is cumbersome and the processing time is long.
If the one-bath method is used for dyeing, there is a problem of poor homochromaticity due to the large difference in the dyeing performance of the two blended or interwoven fibers.

Embodiment 1

[0018] A comfortable silk fabric, the warp is made of 20 / 22D silk, the weft is made of 40S Lenzing Modal, and five pieces of three-flying satin weave are used. The front side mainly reveals the silk yarn, and the back side mainly reveals the modal yarn.

[0019] A dyeing method for comfortable silk fabrics: Dyeing with reactive dyes and one-bath one-step dip-dyeing process, low-temperature dyeing, adding anti-dyeing agent at 30°C, adding dye after the dyeing vat runs for 20 minutes, and then adding NaCl in 3 times, each interval 7min, continue to run for 30min, then add soda ash in 3 times, each interval is 7min, slowly heat up to 90°C, heating rate 1.5°C / min; keep warm and dip for 40min, drain, add water and heat up to 90°C, soap for 15min, drain , to complete the dyeing process;

[0020] Further, the dyes are Cohuasu G Black, Cohuasu 3BS Red and Cohuasu 3RS Yellow;

[0021] Further, the dosage of the dyes is 60g / L of Kehuasu G black, 8.5g / L of Kehuasu 3BS red, and 2.8g / L of...

Embodiment 2

[0026] A comfortable silk fabric, the warp is made of 20 / 22D silk, the weft is made of 50S Lenzing Modal, and five pieces of three-flying satin weave are used. The front side mainly reveals silk yarn, and the back side mainly reveals modal yarn.

[0027] A dyeing method for comfortable silk fabrics: Dye the fabric with reactive dyes and one-bath one-step dip-dyeing process, enter the dyeing at low temperature, add anti-dyeing agent at 30°C, add dye after the dyeing vat runs for 25 minutes, and then add NaCl in 4 times, Each interval is 8 minutes, continue to run for 5 minutes, add soda ash in 45 times, each interval is 8 minutes, slowly heat up to 90°C, heating rate is 2°C / min, keep warm and dip for 45 minutes, drain, add water, heat up to 90°C, and soap for 15 minutes , Drainage, complete the dyeing process.

[0028] Further, the dyes are Cordair G black, Cordair 3BS red and Cordair 3RS yellow.

[0029] Further, the dosage of the dyes is 60 g / L of Kehuasu G Black, 8.5 g / L of...

Embodiment 3

[0034] A comfortable silk fabric, the warp is made of 20 / 22D silk, the weft is made of 60S Lenzing Modal, and five pieces of three-flying satin weave are used. The front side mainly reveals the silk yarn, and the back side mainly reveals the modal yarn.

[0035] Another object of the present invention is to provide a dyeing method for comfortable silk fabrics: use reactive dyes and one-bath one-step dip-dyeing process to dye the fabrics, enter dyeing at low temperature, add anti-dyeing agent at 30°C, and add dyes after the dyeing vat runs for 20 minutes , and then add NaCl in 5 times, with an interval of 10 minutes each time, continue to run for 30 minutes, then add soda ash in 5 times, with an interval of 10 minutes each time, slowly raise the temperature to 90 ° C, the heating rate is 1.5 ° C / min, keep warm and dip for 50 min, drain, and then add water Raise the temperature to 90°C, soap for 15 minutes, and drain the liquid to complete the dyeing process.

Abstract

The invention belongs to the field of textiles and relates to a comfortable silk fabric and a dyeing method thereof. The fabric is characterized in that silk yarns and modal yarns are interwoven by satin weaves to expose the silk yarns on the front surface of the fabric and expose the modal yarns on a skin contacting surface of the fabric, and accordingly comfort and glossiness can be kept and highlighted to the greatest extent. By the dyeing method of the comfortable silk fabric, the problem of poor color uniformity in double-component silk fabric dyeing is effectively solved, dyeing saturability is improved, and color purity is enhanced.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a comfortable silk fabric and a dyeing method thereof. Background technique [0002] Natural fiber silk has irreplaceable luster and drapability, and also has a very soft feel. It is often used in higher-end textile products. Its appearance is high-end and shiny, but its price is also high. In this field, in order to further improve the wearing performance of real silk and reduce the cost to make the use of real silk more popular, other natural or chemical fibers are often used for blending or interweaving with real silk to obtain fabrics with excellent comprehensive performance and low cost, such as Silk cotton, silk linen fabrics, etc. When dyeing and processing real silk two-component fabrics, in order to obtain good homochromatic products, two dyes are usually used for one-bath two-step dyeing or two dyes for two-bath dyeing. The production process is cumbersome and the processing ti...
