Problems solved by technology

[0003] The current dyeing mostly adopts overflow dyeing. The overflow dyeing process has problems such as complicated procedures, high energy consumption, large amount of additives, large discharge volume, and long time-consuming; Blue is the aggregation of planar structure and high-concentration electrolyte, causing color spots on the surface of the fabric; fluffing or pilling of the fabric caused by external mechanical stretching or friction; longitudinal creases that may appear in knitted fabrics; dyeing If the time is too long, the time to reach the dynamic equilibrium will be mistaken as not enough, resulting in problems such as the dye that has already undergone a bond reaction is broken, and the post-treatment is not fully removed.

Embodiment 1

[0033] An emerald green airflow dyeing process for jersey according to an embodiment of the present invention, comprising: a setting machine and an airflow dyeing machine, characterized in that the inner wall surface of the dyeing machine cylinder is polished with high precision, and the dyeing process includes: cotton fiber, The jersey cloth woven by one or several kinds of modal fiber and spandex fiber is sequentially carried out S1: pre-setting; S2: pre-treatment; S3: dyeing; S4: post-treatment; S5: post-finishing;

[0034] Include the step of adding the Yuanming powder of 60g / L and 1.3-1.7ml / L smoothing agent in the step of described S3 dyeing.

[0035] When the air-flow dyeing machine dyes the jersey, there is no need for seaming and one process is saved. Because the active emerald blue has a planar structure and high-concentration electrolytes have aggregated and pedicled, resulting in stains on the surface of the fabric. In the dyeing process, 60g / L sodium sulfate is ad...

Embodiment 2

[0037] Embodiment 2, on the basis of the foregoing embodiments, the S1 presetting process is:

[0038] S101: put the jersey into the setting machine, and raise the temperature to 160°C-210°C at a speed of 5-10°C / min per second;

[0039] S102: Set the speed of the pre-setting machine to 20 yards per minute, the up and down wind volume to 80%-95%, the overfeed to 60%-80%, and the rate of squeezing liquid to 85%-90%. The width of the pre-setting machine is 105%-115% of the light gray cloth, let stand for 30-60 minutes.

[0040] Through the matching relationship between the air volume and the linear speed of the cloth lifting wheel, the fabric has an expansion process after leaving the cloth guide tube, and the position of the bundle is constantly changed, so that the folds are unfolded rapidly, so that the fabric will not produce creases, thereby avoiding creases at the creases Dye adsorption varies.

Embodiment 3

[0041] Embodiment three, on the basis of the foregoing embodiments, the S2 pretreatment process is:

[0042] S201: Put the jersey into the dyeing vat at a bath ratio of 1:3.5, raise the temperature of the dyeing vat to 35°C and let it stand for 1 minute, add 0.8-1.2m / L degreasing agent, 2.0-3.0ml / L scouring agent, defoaming agent agent, 1.0-2.0ml / L lubricant in the bath, 2-4g / L scouring enzyme and 2-4g / L 95% soda ash and let it stand for 5 minutes;

[0043] S202: Add 7-9ml / L hydrogen peroxide at a constant speed for one minute, raise the temperature at a constant speed of 2°C / m to 115°C for 20 minutes, cool down to 80°C at a speed of 2°C / m, and remove the residual liquid;

[0044] S203: Enter water according to the bath ratio of 1:3.5, directly raise the temperature to 90°C, wash with water for 5 minutes, and drain the residual liquid;

[0045] S204: Enter water according to the bath ratio of 1:3.5, adjust the pH value to 4.5-5.5 with 1ml / L acetic acid, add 0.8ml / L deoxygenas...

Abstract

ThThe invention relates to jade green dyeing technology for single jersey. Hemming process is not needed and one process is omitted, based on dyeing technology, anhydrous sodium sulphate is added firstly and uniformly distributed on a cloth surface, in order to solve the problem of color spots; a smooth agent is added in order to eliminating the problem of fluffing or piling of fabrics due to stretching or friction by extraneous mechanical action; by means of matching relation of air quantity and linear velocity of cloth lifting rollers, after the fabric leaves a cloth guiding tube, an expansion process is provided, bundling position is continuously changed, so that folding parts can be rapidly expanded, creases of the fabric are not generated, and difference of dye adsorption generated at the crease parts is avoided. the fabric has good effects in the aspects of capillary effect, fineness, hand feeling, weight loss, and the like, and the technology saves time, auxiliary agents, and has low energy consumption and low emission; the technology enables the fabric to have better indices of each color fasteness and guarantees level-dyeing property; by means of control of dyeing time, the problems of uneven dyeing and the like due to bond breaking of dye after bond type reactions are prevented.

Description

technical field [0001] The invention relates to an emerald green jersey dyeing process, in particular to an emerald green airflow dyeing process for jersey. Background technique [0002] With the increasing emphasis on environmental protection and energy consumption in the society, in the dyeing industry, the airflow dyeing machine achieves low consumption due to its low bath ratio, and is praised by the industry as an environmental protection and energy-saving dyeing machine. The emergence of any new things will bring with it Related problems, the research on new suitable air-flow dyeing process is imminent. [0003] The current dyeing mostly adopts overflow dyeing. The overflow dyeing process has problems such as complicated procedures, high energy consumption, large amount of additives, large discharge volume, and long time-consuming; Blue is the aggregation of planar structure and high-concentration electrolyte, causing color spots on the surface of the fabric; fluffing...
