Embodiment 1

[0021] Colored cotton jersey, soak in warm water at 60-70°C for 10 minutes, add 2.0 g / L enzyme (pectinase: cellulase mass ratio 70:30), control the bath ratio to 1:20, and then adjust the pH value to 6.0, The temperature is 50°C, soak for 75 minutes, raise the temperature to 85°C, keep warm for 10 minutes, and shake dry for later use.

[0022] According to 40g / L moisturizing finishing agent CBS, use acetic acid to adjust the pH to 6-7, prepare the finishing liquid, dip and pad the colored cotton jersey, one dip and one pad, the liquid retention rate is 100%, dry at 100°C, and bake at 150°C Bake for 45 seconds.

[0023] After moisturizing finishing, the moisturizing performance of colored cotton is evaluated by moisture absorption rate and moisture permeability:

[0024] (1) Moisture absorption rate. Dry the colored cotton fabric to a constant weight, weigh it (accurate to 0.0001g), place it in a constant temperature and humidity box for 24 hours at a constant temperature of ...

Embodiment 2

[0037] For colored cotton ribs, soak in warm water at 60-70°C for 10 minutes, add 2.0g / L enzyme (pectinase: cellulase mass ratio 70:30), control the bath ratio to 1:20, then adjust the pH value to 6.0, the temperature Soak at 50°C for 75 minutes, heat up to 85°C, keep warm for 10 minutes, and shake dry for later use.

[0038] Use 5% moisturizing finishing agent CBS, adjust the pH to 6-7 with acetic acid, prepare the finishing solution, impregnate the rib of colored cotton, control the bath ratio to 1:10, soak at 50°C for 30min, then centrifugally dehydrate, and dry at 100°C.

[0039] After finishing, the moisture absorption rate of colored cotton rib increases by 100%, and the moisture permeability increases by 50%.

Embodiment 3

[0041] Colored cotton weft plain knitted fabrics, soaked in warm water at 60-70°C for 10 minutes, added 2.0 g / L enzyme (pectinase: cellulase mass ratio 70:30), controlled bath ratio to 1:20, and then adjusted the pH value = 6.0, temperature 50°C, soak for 75 minutes, raise the temperature to 85°C, keep warm for 10 minutes, and shake dry for later use.

[0042] According to 60g / L moisturizing finishing agent CBS, use acetic acid to adjust the pH to 6-7, prepare the finishing solution, pad the colored cotton knitwear, one dipping and one padding, the liquid retention rate is 80%, dry at 100°C, bake at 160°C Bake for 30 seconds.

[0043] After finishing, the moisture absorption rate of the colored cotton weft plain knitted fabric increases by 70%, and the moisture permeability increases by 45%.

Abstract

The invention discloses a method for hydrating and finishing natural colored cotton knitwear, comprising the following: (1) a step of pretreatment, which is to soak the colored cotton knitwear into the clear water at the temperature of between 60 and 70 DEG C for 10 to 20 minutes, to add a mixture of pectase and cellulase with a concentration of 2.0g / L, to control the bath ratio as 1:20, to adjust the pH value equal to 6.0, and the temperature of 50 DEG C, to soak for 70 to 90 minutes, then to heat up the mixture to 85 DEG C, to preserve the temperature for 10 to 20 minutes and to spin dry the mixture for spare; (2) a step of hydrating and finishing, which is to prepare a finishing liquor by adopting a hydrating finishing agent CBS with a concentration of between 30 and 60g / L and adjusting the pH value to be between 6 and 7 by acetic acid and to hydrate and finish the colored cotton knitwear by the dipping or padding technique. The method has simple process, convenient operation, easy control, stable performance of the finished colored cotton and good hydrating effect.

Description

technical field [0001] The invention belongs to the finishing field of textiles, in particular to a method for moisturizing and finishing natural colored cotton knitwear. Background technique [0002] Natural colored cotton, referred to as colored cotton for short, is a new type of textile material that has natural colors such as red, yellow, green, brown, etc. The main reason why natural colored cotton attracts people's attention is its environmental protection characteristics, which are mainly reflected in: natural colored cotton has natural color, and does not need to be dyed in the production process of textile products; its waste can be reused or naturally degraded, which caters to the needs of human beings. The slogan of "green revolution" has reduced environmental pollution, and the development and production of ecological, environmentally friendly and healthy green textiles will help the country continue to maintain its status as a major textile exporter, and it has ...
