Embodiment 1

[0017] The steam dyeing fixation process of embodiment 1 wool fiber comprises the following steps:

[0018] S1, configure wool fibers, place the wool fibers in high-pressure steam equipment, conduct a steaming treatment at 110°C, then take them out and dry them;

[0019] S2: Dye the steamed wool in a reactive dye mixed solution at 60°C, where the composition of the reactive dye mixed solution includes reactive dye 2% (o.m.f), glacial acetic acid 6% (o.m.f), NT02 type wool low temperature dyeing Auxiliary 2% (o.m.f), wool penetrant 6g / L, sodium sulfide 35g / L, Pingpingjia 0.5g / L, ammonium sulfate 3g / L;

[0020] S3: Soaping, drying, placing the dried wool in high-pressure steam sterilization equipment, and performing a second steaming treatment at 110°C;

[0021] S4: wash again with distilled water, and dry.

[0022] The treatment time of one steaming treatment in S1 is 30min.

[0023] The processing time of the secondary steaming treatment in S3 is 120s.

Embodiment 2

[0025] The difference between embodiment 2 and embodiment 1 is that

[0026] S1 The steaming temperature is 130°C, and the steaming time is 30 minutes;

[0027] S2: Dye the steamed wool in a reactive dye mixed solution at 60°C, where the composition of the reactive dye mixed solution includes reactive dye 2% (o.m.f), glacial acetic acid 6% (o.m.f), NT02 type wool low temperature dyeing Auxiliary 2% (o.m.f), wool penetrant 6g / L, sodium sulfide 35g / L, Pingpingjia 0.5g / L, ammonium sulfate 3g / L;

[0028] S3: The secondary steaming treatment temperature is 110°C, and the treatment time is 60s.

[0029] The wool in S1 is wool pretreated with urea. The urea pretreatment is as follows: immerse the wool in urea aqueous solution at 70-90°C for 5 minutes, and dry at low temperature. The concentration of urea in the urea aqueous solution is 40g / L.

Embodiment 3

[0031] The difference between embodiment 3 and embodiment 2 is that the steaming temperature of S1 is 120° C., and the steaming time is 35 minutes;

[0032] S2: Dye the steamed wool in a reactive dye mixed solution at 55°C, where the composition of the reactive dye mixed solution includes 2.5% (o.m.f) reactive dye, 5% (o.m.f) glacial acetic acid, low-temperature dyeing of NT02 wool Auxiliary 2.5% (o.m.f), wool penetrant 4.5g / L, sodium sulfide 42g / L, Pingpingjia 0.4g / L, ammonium sulfate 5.5g / L;

[0033] S3: The secondary steaming treatment temperature is 100°C, and the treatment time is 90s.

[0034] The wool in S1 is wool pretreated with urea. The urea pretreatment is as follows: soak the wool in urea aqueous solution at 80°C for 3 minutes, and dry at low temperature. The concentration of urea in the urea aqueous solution is 55g / L.

[0035] The urea aqueous solution also contains penetrant JFC.

Abstract

The invention discloses a steaming dye fixing technology for wool fiber. The technology comprises the steps as follows: S1, preparing wool fiber, placing the wool fiber in high-pressure steam equipment for primary steaming treatment at 110-130 DEG C, and then, taking out and drying the wool fiber; S2, dyeing with reactive dye; S3, performing soaping and drying, and placing the dried wool in the high-pressure steam sterilization equipment for secondary steaming treatment at 90-110 DEG C; S4, washing the wool with distilled water again and drying the wool. Wool scales subjected to primary steaming treatment warp, so that the probability that dye enters fiber is greatly increased. The dyed wool fiber is subjected to secondary steaming treatment, so that the dye further enters the wool fiber,and the dye uniformity and dye permeability of dyed fiber are improved.

Description

technical field [0001] The invention belongs to the technical field of wool dyeing treatment, and in particular relates to a wool fiber steam dyeing and fixing process. Background technique [0002] Wool fiber is an earlier natural fiber used by humans. It not only has good thermal performance, but also has a soft and comfortable feel. It is an ideal textile fiber raw material. However, the dyeing of wool is affected to a certain extent due to the existence of the scale layer on the surface of the fiber. At present, many researchers try to increase the warping angle of wool fiber scales through many methods, even remove the scale layer on the surface of wool fibers, or improve the dyeing performance by changing the internal structure of wool fibers, such as ultrasonic pretreatment, so that wool fibers The scale layer is reduced, the warp angle of the scale layer is increased, and the crystallinity of the wool fiber is reduced by ultrasonic treatment, which improves the dyei...
