Embodiment 1

[0023] Cut the cashmere fabric into a sample of 5cm×5cm, put it into the low-temperature plasma reaction chamber, and vacuumize it. When the pressure in the reaction chamber reaches 4Pa, start to introduce air to balance the vacuum degree in the reaction chamber at 53Pa, and then treat the electrodes placed in the processing chamber. A voltage was applied, glow discharge was performed, and each discharge treatment was performed for 90 seconds with a power of 100 W.

[0024] The cashmere fabric after the above-mentioned low-temperature air plasma treatment was dyed according to the following conditions.

[0025] Dye Recipe % (o.w.f. to fabric weight)

[0026] Weak acid red B 2

[0027] Pingping plus O-10 0.3

[0028] Acetic acid 2

[0029] pH 5

[0030] Bath ratio 1:50

[0031] Dyeing process: Add the cloth sample when the above-mentioned prepared dyeing bath is heated to 30°C, and heat up at a rate of 2°C / min. After boiling, keep it for 20 minutes, take out the cloth samp...

Embodiment 2

[0037] Cut the cashmere fabric into a sample of 5cm×5cm, put it into the low-temperature plasma reaction chamber, and vacuumize it. When the pressure in the reaction chamber reaches 7Pa, start to introduce oxygen to balance the vacuum degree in the reaction chamber at 67Pa, and then treat the electrodes placed in the processing chamber. Voltage is applied to perform glow discharge, and discharge treatment is performed for 300s with 100W power.

[0038] The cashmere fabric after the above-mentioned low-temperature air plasma treatment was dyed according to the following conditions.

[0039] Dye Recipe % (o.w.f. to fabric weight)

[0040] Lanna free and easy red 2B 2

[0041] ABIG SET 3

[0042] Acetic acid 2

[0043] pH 4.5

[0044] Bath ratio 1:30

[0045] Dyeing process: Add the cloth sample when the above-mentioned prepared dyeing bath is heated to 30°C, and heat up at a rate of 2°C / min. After boiling, keep it for 20 minutes, take out the cloth sample and rinse it twice...

Embodiment 3

[0054] Cut the cashmere fabric into a sample of 5cm×5cm, put it into the low-temperature plasma reaction chamber, and vacuumize it. When the pressure in the reaction chamber reaches 10Pa, start to introduce argon gas to balance the vacuum degree in the reaction chamber at 160Pa. Voltage is applied to the electrodes to perform glow discharge, and discharge treatment is performed for 300 seconds with 20W power.

[0055] The cashmere after the above-mentioned low-temperature plasma treatment was put into ammonia water with a concentration of 5% by weight and a bath ratio of 1:20, heated to 30° C. and kept for 20 minutes. After taking it out, perform low-temperature staining under the following conditions.

[0056] Dye Recipe % (o.w.f. to fabric weight)

[0057] Lanna free and easy yellow 4GN 2

[0058] ABIG SET 3

[0059] Acetic acid 2

[0060] pH 4.5

[0061] Bath ratio 1:30

[0062] Dyeing process: When the dyeing bath prepared above is heated to 35°C, add the cloth sampl...

Abstract

The invention discloses a staining process for cashmere fiber or cashmere fabric which comprises the steps of, placing the cashmere fiber or cashmere fabric into treatment chamber, lowering the pressure in the treatment chamber to be 10Pa or below, adjusting the pressure in the chamber to be 10-200Pa through non-polymer gas, exerting voltage to the electrode arranged in the processing chamber for low-temperature plasma treatment, and proceeding coloration.

Description

technical field [0001] The invention relates to the field of dyeing and finishing of textiles, in particular to a method for dyeing cashmere fibers or cashmere fiber fabrics. Background technique [0002] Cashmere has the reputation of "the crown of fiber" and "soft gold". The world's cashmere production is less than 1% of the total wool production, and it is a precious raw material for the wool spinning industry. Compared with wool, cashmere has thinner fibers, shorter length, and slightly weaker strength. Compared with wool, cashmere is smoother, softer, lighter, delicate, warm, and comfortable to wear. [0003] As a high-end and expensive fabric, cashmere cannot directly use the usual wool dyeing process, because the scale density on the surface of cashmere fiber is much smaller than that of wool. During the dyeing process, the dye is dyed faster than wool, especially in piece dyeing. , it is very easy to have quality problems such as dyed flowe...
