Problems solved by technology

However, these methods are difficult to be practical. For example, the alkali treatment method will cause a large amount of pigment loss, which will affect the antibacterial performance of colored cotton products; the liquid ammonia treatment method and supercritical carbon dioxide fluid treatment method require large and expensive equipment.

Embodiment 1

[0025] Embodiment 1, a kind of processing method of high color purity natural brown cotton antibacterial yarn, carries out following steps successively:

[0026] 1) Preparation of dyed cotton fibers: white cotton fibers were placed in natural indigo dyeing liquor at a temperature of 50°C at a bath ratio of 1:150, and the dyeing time was 30 minutes. The dyeing liquor contained 1.2 g / L natural indigo dye, 8.0 g / L L of NaOH, 10.0g / L of sodium hydrosulfite. After dyeing, wash off the floating color of the fiber with water (until the eluate is colorless), and dry at 50° C. (until constant weight) to obtain dyed cotton fiber.

[0027] The color values ​​of the obtained dyed cotton fibers are: L*=22, a*=52, b*=-105.

[0028] 2) Spinning: first prepare natural brown cotton and dyed cotton fibers according to the mass percentage of 92:8, and then carry out the following procedures in sequence: combing → mixing wet → opening → carding machine → drawing frame → roving frame → spinning f...

Embodiment 2

[0030] Embodiment 2, a kind of processing method of high color purity natural brown cotton antibacterial yarn, carry out following steps successively:

[0031] 1) Preparation of dyed wool fiber: place the wool in a natural indigo dye solution at a temperature of 50°C at a liquor ratio of 1:100, and the dyeing time is 60 minutes. The dye solution contains 1.8g / L natural indigo dye, 1.5g / L L penetrant JFC, 1.5g / L penetrant Pingping plus O, 1.0g / L Yuanming powder. After dyeing, wash the fiber with water to remove floating color, and dry it at 50°C to obtain dyed wool fiber.

[0032] The color values ​​of the obtained dyed wool fiber are: L*=45, a*=66, b*=-68.

[0033] 2) Spinning: firstly prepare natural brown cotton and dyed wool fiber according to the mass percentage of 99:1, and then carry out the following procedures in sequence: combing→mixing and wetting→opening→carding machine→drawing frame→roving frame→spinning frame → Winding process to obtain a blended yarn with a lin...

Embodiment 3

[0034] Embodiment 3, a kind of processing method of high color purity natural brown cotton antibacterial yarn, carries out following steps successively:

[0035] 1) Preparation of dyed spun silk fiber: the spun silk is placed in the reactive blue 2 dyeing solution with a bath ratio of 1:50 at a temperature of 60° C., and the dyeing time is 90 minutes. The dyeing solution contains 1.2 g / L reactive blue 2 dye, 2.0g / L penetrating agent JFC, 1.5g / L leveling agent Pingping plus O. After dyeing, wash the floating color of the fiber with water, and dry it at 50°C to obtain dyed spun silk fiber.

[0036] The color values ​​of the obtained dyed spun silk were: L*=34, a*=53, b*=-89.

[0037] 2) Spinning: first prepare natural brown cotton and dyed spun silk fibers according to the mass percentage of 97:3, and then carry out the following procedures in sequence: combing → mixing wet → opening → carding machine → drawing frame → roving frame → spinning Machine→winding process to obtain ...

Abstract

The invention discloses a processing method for natural brown cotton antibacterial yarn with high color purity. Natural brown cotton and dyed fiber are mixed as raw materials. In the raw material, the mass content of natural brown cotton is 90% to 99.8%. Blended yarn to obtain natural brown cotton antibacterial yarn with high color purity. The color purity of the natural brown cotton yarn processed by the method of the invention is obviously improved, and the color system remains unchanged; compared with the existing method, the antibacterial performance of the natural brown cotton yarn obtained by the invention is basically unchanged. The method is simple and easy to carry out on the existing spinning processing equipment, and the processing cost is low.

Description

technical field [0001] The invention relates to a processing method of natural colored cotton antibacterial yarn with high color purity. Background technique [0002] Natural colored cotton does not require bleaching and dyeing, and has significant environmental and economic advantages over ordinary white cotton. The development of natural colored cotton production and processing technology is in line with the development direction of the textile industry. Natural colored cotton has good antibacterial and anti-oxidation functions, and is a natural functional fiber. [0003] However, natural colored cotton still has some defects that have not been resolved, such as monotonous color system, hazy and not bright enough color, and the color will gradually become lighter with the increase of washing times. In the final analysis, this is caused by the complex of natural colored cotton pigments. [0004] At present, many methods for improving the color purity or depth of natural ...
