Description

Technical Field

[0001] This invention relates to a fabric dyeing process, and more particularly to a production process for an antibacterial, anti-mite, regenerated milk velvet environmentally friendly fabric. Background Technology

[0002] Recycled milk silk yarn, due to its certain antibacterial and anti-mite properties, is used as a raw material for making antibacterial and anti-mite fabrics. However, because the overall antibacterial and anti-mite effect of recycled milk silk yarn is generally limited, the fabric needs to undergo further antibacterial and anti-mite treatment in subsequent dyeing and finishing processes. However, when using traditional dyeing and finishing processes to treat milk silk velvet fabrics for antibacterial and anti-mite purposes, the overall antibacterial and anti-mite treatment effect is unsatisfactory, and it can also lead to poor even dyeing in some areas and a tendency for color spots to appear. Therefore, existing technologies suffer from unsatisfactory antibacterial and anti-mite treatment effects and poor dyeing results. Summary of the Invention

[0003] The purpose of this invention is to provide a production process for an antibacterial and anti-mite recycled milk velvet eco-friendly fabric. This invention effectively improves the antibacterial and anti-mite treatment effect and enhances the dyeing effect.

[0004] The technical solution of this invention: A production process for an antibacterial and anti-mite regenerated milk velvet environmentally friendly fabric, comprising the following steps:

[0005] A. The fabric is pretreated to obtain product A;

[0006] B. Dye product A to obtain product B;

[0007] C. Perform preliminary shaping treatment on product B to obtain product C;

[0008] The initial design temperature is 170-180℃, the vehicle speed is 25-30m / min, and the wind speed is 1400-1600 revolutions per minute;

[0009] D. Apply a continuous three-stage brushing method to product C to obtain product D.

[0010] E. Shear the hair off product D to obtain product E;

[0011] F. Use a water washing machine to perform a reductive wash on product E to obtain product F;

[0012] Product E is sequentially washed in four washing tanks of a washing machine. In the first washing tank, 3.5-4.5 g / L of alkali and 2.5-3.5 g / L of sodium hydrosulfite are added, and the washing temperature is 85℃.

[0013] Add 1.5-2.5 g / L of alkali and 1-2 g / L of sodium hydrosulfite to the second washing tank, and the washing temperature is 85-95℃;

[0014] The third washing tank uses hot water at a temperature of 90-100℃ for cleaning;

[0015] The fourth washing tank is treated with a dyeing acid at a temperature of 55-65℃ and a concentration of 2.5-3.2 g / L.

[0016] G. Process F product to obtain the finished product;

[0017] During the settling process, the temperature is 140-150℃, the vehicle speed is 35-45m / min, the wind speed is 1500-1700 rpm, the upper overfeed is 99-102 yards, and the lower overfeed is 102-105 yards.

[0018] In the aforementioned production process of an antibacterial and anti-mite recycled milk velvet eco-friendly fabric, the fabric is woven from recycled milk yarn.

[0019] In the aforementioned production process of an antibacterial and anti-mite recycled milk velvet eco-friendly fabric, the specific pretreatment steps are as follows: Adjust the dyeing vat temperature to 40℃, add 2g / l of degreasing agent and 2g / l of refining agent, then raise the temperature to 85℃ at a rate of 3℃ / min and hold for 20 minutes; finally, lower the temperature to 60-70℃ at a rate of 3℃ / min.

[0020] In the aforementioned production process of an antibacterial and anti-mite regenerated milk velvet eco-friendly fabric, the specific dyeing process is as follows: In a dyeing vat at 60-70℃, a leveling agent, a dyeing accelerator, a dyeing acid, and a disperse dye are added sequentially. Then, the temperature is increased to 85-95℃ at a rate of 2-3℃ / min and held for 3-7 minutes. Next, the temperature is increased to 105-115℃ at a rate of 2-3℃ / min and held for 3-7 minutes. Then, the temperature is increased to 120-130℃ at a rate of 2-3℃ / min and held for 30-40 minutes. Finally, the temperature is decreased to 75-85℃ at a rate of 2.5-3.5℃ / min.

[0021] In the aforementioned production process of an antibacterial and anti-mite recycled milk velvet eco-friendly fabric, softener and napping agent are added to the rolling mill groove during the initial shaping.

[0022] In the aforementioned production process of an antibacterial and anti-mite regenerated milk velvet eco-friendly fabric, during the shearing process, the shearing flat knife is fixed, the rotary speed is 850-950 revolutions, the tension of the front guide roller is 1.8-2.2%, and the tension of the rear guide roller is 1.8-2.2%.

[0023] In the aforementioned production process of an antibacterial and anti-mite recycled milk velvet eco-friendly fabric, the specific process of the three-stage napping method is as follows:

[0024] First stage: cylinder 65-75 rpm, clockwise 45-55 rpm, counterclockwise 25-35 rpm; front guide roller tension 1-1.4%, rear guide roller tension 1.8-2.2%, lead roller tension 2.8-3.2%;

[0025] Second stage: cylinder 65-75 rpm, clockwise 40-50 rpm, counterclockwise 20-30 rpm; front guide roller tension 1-1.4%, rear guide roller tension 1.8-2.2%, lead roller tension 2.8-3.2%;

[0026] Third stage: cylinder 65-75 rpm, clockwise 40-50 rpm, counterclockwise 20-30 rpm; front guide roller tension 1-1.4%, rear guide roller tension 1.8-2.2%, and lead roller tension 2.8-3.2%.

[0027] In the aforementioned production process of an antibacterial and anti-mite regenerated milk velvet eco-friendly fabric, during the forming process, the tensions of the three fabric pulling rollers are 90-110N, 90-110N, and 90-110N, respectively; at the same time, antibacterial and anti-mite additives are added to the rolling mill groove.

[0028] Compared with existing technologies, this invention sequentially processes recycled milk velvet fabric through pretreatment, dyeing, initial setting, napping, shearing, reduction washing, and final setting. By strictly defining each process step and specific process parameters, it can effectively improve the antibacterial and anti-mite treatment effect and enhance the dyeing effect. Specifically, this application solves the dyeing difficulties of some disperse dyes with poor evenness and prone to color spots, such as the problems of color spots and uneven dyeing of colors like indigo, turquoise, and scarlet. By employing two steps—initial setting and final setting—to complete the fabric setting process, the antibacterial and anti-mite treatment effects are improved. The three-stage napping process results in a dense, uniform, delicate, and soft nap, effectively preventing four-sided napping and ensuring the three-dimensionality of the pile, which also benefits the effectiveness and quality of subsequent antibacterial and anti-mite treatments. Four washing machine processes ensure improvements in the fabric's wash fastness, rubbing fastness, and perspiration fastness. In summary, this invention effectively improves the antibacterial and anti-mite treatment effects and enhances dyeing results. Detailed Implementation
