Technical Field

The invention relates to the technical field of fabrics, in particular to an ultra-soft grey cloth and a biological enzyme treatment method thereof.

Background

The grey fabric refers to fabric which is made of related fibers through spinning and weaving and is not dyed and finished.

The grey cloth made of the cotton fibers has fluff on more or less surfaces, the flatness is poor, meanwhile, the surfaces of the grey cloth are slightly yellow due to the characteristics of raw materials, and meanwhile, the hand feeling of the fabric is relatively poor. Improvements are therefore desirable.

Disclosure of Invention

The present invention is directed to solving, at least to some extent, one of the technical problems in the related art. Therefore, an object of the present invention is to provide an ultra-soft gray fabric having excellent antibacterial properties, soft hand feeling, high mechanical strength, and high surface gloss.

The technical scheme of the invention is as follows:

an ultra-soft white grey fabric is prepared by blending cotton fibers and soybean protein fibers, treating with mixed enzyme, and tentering and orienting.

Furthermore, the cotton fibers in the ultra-soft white gray fabric account for 80-90% of the total mass of the fabric, and the weight loss rate of the fabric after being treated by the blending enzyme is 3-5%.

The biological enzyme treatment method of the ultra-soft white gray fabric comprises the following steps:

1) preheating the woven grey cloth and carrying out ultrasonic treatment;

2) preparing enzyme liquid, dipping the preheated fabric in the enzyme liquid, and assisting with ultrasonic treatment;

3) soaking and cleaning the soaked fabric in water for 2-3 times;

4) placing the cleaned fabric in a suspension containing nano titanium dioxide with the mass of 0.06% -0.2% of the fabric, soaking for 30-50min at 80-90 ℃, and then pre-drying;

Further, the ultrasonic power in the step 2) is 100-140W, the frequency is 20-30KHz, and the ultrasonic treatment is carried out for 10-15 min.

Furthermore, a surfactant is added into the solution in the step 4), and the addition amount is 2-5 g/L of the soaking solution.

Further, the pre-drying condition in the step 4) is drying for 4-8min at the temperature of 80-95 ℃.

The invention has the beneficial effects that: by adopting the blended fabric of the cotton fibers and the soybean fibers, the overall strength of the fabric is higher, and meanwhile, the fabric has better glossiness, is stiff and smooth, does not wrinkle and has smoother hand feeling; the fabric is preheated and subjected to high-power ultrasonic treatment, so that certain pores can be generated on the surface of the fabric, and part of the structure is damaged, thereby facilitating the subsequent treatment of enzyme liquid; the mixed enzyme treatment is adopted, so that fiber fluff on the surfaces of cotton fibers and soybean fibers can be hydrolyzed, the glossiness of the surfaces of the fibers is improved, meanwhile, the composite enzyme solution has a synergistic effect, the enzymolysis speed is increased by matching with ultrasonic treatment with relatively low power, the enzymolysis treatment can be carried out on the inner part of a yarn core, the internal structure of the yarn is relatively loose, and the surface of the fibers is provided with certain holes, so that when nano titanium dioxide is impregnated, nano titanium dioxide particles can enter a yarn core layer of the fabric; and (3) pre-drying to ensure that the fabric has a certain water content, so that the surface of the nano titanium dioxide is in a wet state and is more firmly combined with fibers in the yarns, and after tentering, fiber spaces in the yarns become compact, fiber pores in the yarns can be filled, and the titanium dioxide is embedded.
