Problems solved by technology

[0005] It can be seen from the above existing technologies that the current process of alkali treatment of cotton fibers has been phased out, but it is well known that biological enzymes are organic substances with catalytic effects produced by living cells, most of which are proteins, and a very small part is RNA, so It has high requirements on the external temperature and living environment, and it is easy to inactivate, which puts forward higher requirements for mass production

Embodiment 1

[0056] A kind of preparation method of modified cotton fiber, comprises the steps:

[0057] (1) Sodium hydroxide solution with a concentration of 7g / L was used to impregnate the cotton fibers at 80°C for 20 minutes, and then washed with deionized water until neutral to obtain the treated cotton fibers;

[0058] (2) disperse graphene oxide and sodium sulfate in deionized water to obtain modified slurry, in the modified slurry, the concentration of graphene oxide is 0.1wt%, and the concentration of sodium sulfate is 30g / L;

[0059] (3) Immerse the cotton fiber treated in step (1) in the modified slurry prepared in step (2) according to the bath ratio of 1:100, and immerse it at 40° C. for 50 min to modify it;

[0060] (4) the cotton fiber woven fabric after step (3) is processed carries out following aftertreatment successively:

[0061] Soaking soap treatment: treatment temperature is 80-100°C, time is 10 minutes, soaking liquid contains 2g / L sodium carbonate and 1g / L soap oil...

Embodiment 2-6

[0068] The difference with Example 1 is that in step (1), the alkali treatment temperature and time are respectively 100°C, 10min (Example 2); 90°C, 13min (Example 3); 85°C, 16min (Example 4); 110°C, 7min (Example 5); 70°C, 40min (Example 6).

Embodiment 7-11

[0070] The difference with Example 1 is that in the modified slurry of step (2), the concentration of graphene oxide is respectively 0.05wt% (Example 7); 0.25wt% (Example 8); 1wt% (Example 9) ; 5wt% (Example 10); 6wt% (Example 11).

Abstract

The invention relates to a modifying method of a product containing cotton fibers. The method includes (1) a step of treating cotton fibers with an alkali and then washing the cotton fibers until neutrality; (2) a step of preparing modifying slurry including a graphene material and auxiliary dye; (3) a step of soaking the cotton fibers treated by the step (1) into the modifying slurry prepared in the step (2), and performing modification; (4) a step of further treating the cotton fibers treated by the step (3) to obtain modified cotton fibers. Cotton fiber modification is achieved by bonding the graphene material and cotton fibers so that the graphene material can be firmly bonded to the cotton fibers. Functions of the product containing the cotton fibers do not decrease obviously along the increase of the number of times of washing, and functions (an antibacterial function, a far infrared function, and the like) are not obviously reduced. In a modification process of the product containing the cotton fibers, related steps and reagents for cotton fiber dyeing can be added to increase bonding soundness between the graphene and the cotton fibers.

Description

technical field [0001] The invention belongs to the field of cotton fiber modification, and in particular relates to a preparation method of modified cotton fiber, obtained product and application. Background technique [0002] Pure cotton fabric is a textile made of cotton as raw material, which is interwoven vertically and horizontally by warp and weft yarns through a loom. Pure cotton fabrics have a wide variety of fabrics with different designs and colors. According to the dyeing method, it can be divided into primary color cotton cloth, dyed cotton cloth, printed cotton cloth and yarn-dyed cotton cloth; it can also be divided into plain weave, twill cloth and forged cloth according to the fabric structure. In order to make cotton fiber fabric more beautiful, coloring is essential. [0003] The master's thesis of Xi'an Institute of Engineering Science and Technology "Research on Cotton Fiber Pretreatment and Dyeing Process" pointed out that alkali treatment is generall...
