Problems solved by technology

[0009] At present, there are two main processing methods for antibacterial fabrics: one is to directly use antibacterial fibers to make various fabrics, the resulting fabrics have long-lasting antibacterial effects and good washability, but have high requirements for antibacterial agents; the other is to process fabrics Antibacterial finishing processing to obtain antibacterial function, antibacterial finishing is to make the fabric have the function of inhibiting the growth of fungi, maintain a hygienic clothing environment, and ensure human health. This processing method is simple, but the washability and antibacterial durability are poor, and there is safety dress problem

Embodiment 1

[0034] The preparation of embodiment 1 functional color spinning fiber

[0035] 1. Modification treatment and dyeing:

[0036]Modification treatment: the modifier (the weight ratio of nano-silver, chitosan and titanium dioxide is 1:75:18) is prepared into a 20% solution with water, and sodium laurate is added to the solution (modifier and sodium laurate The weight ratio is 1:0.3), stirring vigorously to obtain the modified solution; soak the cotton fiber in the modified solution for 10-15min, and then put the fiber soaked in the modified solution into a sealed reaction kettle, at 120°C Keep the temperature constant for 2 hours under the same conditions, after the reaction is completed, soak in absolute ethanol and water for 10-15 minutes, and dry at 70°C to obtain the modified fiber.

[0037] Dyeing: Put the modified fiber into the dyeing vat and use reactive dyes. The dye formula is: 0.2wt% 3BS red, 0.7wt% 3RS yellow, 1.5wt% Yuanqing B; Pour into the dye vat, keep the temp...

Embodiment 2

[0047] The preparation of embodiment 2 functional colored spinning fibers

[0048] Except for the modifier composition, other preparation methods are the same as in Example 1. In this embodiment, the modifier consists of nano-silver, chitosan and titanium dioxide in a weight ratio of 1:70:22.

Embodiment 3

[0049] Embodiment 3 color fastness test

[0050] The functional color spinning fiber prepared by using Examples 1 and 2 is processed into textiles, and according to the national standard GB / T 3920-2008 "Textile Color Fastness Test Color Fastness to Rubbing", the cotton is measured with the YG571 type color fastness tester. The color fastness to rubbing of fibers, in addition, in order to illustrate the effect of the present invention, the following comparative examples are specially set, and the comparative examples are except that the modifying agent is formed, and other preparation methods are all the same as embodiment 1, and the comparative example modifying agent is composed as follows:

[0051]

[0052] The specific results are as follows:

Abstract

The invention belongs to the field of textiles and in particular relates to a colored spun yarn with an antibacterial function, a fabric and a preparation method thereof. The loose fibers used by the functional colored spun yarn are modified by a modifier; the count of the functional colored spun yarn is single yarn or compound yarn of 10-60S; the twist of the single yarn is 300-1300 twist per meter; the twist of the compound yarn is 150-1300 twist per meter; and the modifier consists of nano-silver, chitosan and nanometer titania. The weight ratio of the nano-silver to chitosan to titania is 1:(10-300):(12-50). The invention further provides a colored spun fabric which is prepared from the functional colored spun yarn. Therefore, the colored spun fabric has excellent ultraviolet resistance and antibacterial performance.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a color-spun yarn with an antibacterial function, a fabric and a preparation method thereof. Background technique [0002] The dyeing and finishing process is a process with high energy consumption and high sewage discharge in the textile industry, which has always been criticized by the society. Traditionally, for natural fibers, the color must be obtained through printing and dyeing. [0003] Colored spinning reverses the traditional textile process, and mentions the coloring link before spinning. After the process is changed, it can be made into a blend of cotton, hemp, wool, silk, chemical fiber and other raw materials. Its advantages: First, it completely solves the problem of cylinder difference in gray cloth dyeing. As long as the color is determined in color spinning, it can achieve unlimited batches; second, color spinning solves the dyeing problem of various fabrics...
