The antibacterial warp yarns 1 and the weft yarns 2 are blended and interwoven, so that the antistatic performance of the real silk fabric is improved, and the problem that real silk is prone to wrinkle is greatly solved.

The antibacterial real silk is prepared by directly spinning, cocooning, cocoon cooking and reeling young silkworms, so that the self-made antibacterial real silk achieves more excellent antibacterial property than common real silk; the blending of the antibacterial real silk and the acetate fiber also greatly improves the antistatic and anti-wrinkle effects of the silk fabric.

Example 2

On the basis of the above embodiments, this embodiment explains a preparation method of an antibacterial real silk in an antibacterial and antistatic silk and vinegar interwoven fabric.

The mode of a natural bioreactor of the silkworm baby is mainly applied in the production process of the antibacterial real silk, through a gradient experiment method, eight groups with inorganic substance A contents of 10ppm, 15ppm, 20ppm, 25ppm, 30ppm, 35ppm, 40ppm and 45ppm are used, and through experiments, the silkworm baby has discomfort when the inorganic substance A fed to the silkworm baby exceeds 35 ppm;

compared with the silk antibacterial performance with the inorganic substance A content of 10ppm, 15ppm, 20ppm, 25ppm, 30ppm and 35ppm respectively, when the inorganic substance A content is 20ppm, 25ppm, 30ppm and 35ppm, the obtained silk has more excellent antibacterial property than the common silk, the antibacterial rate is more than 80%, and the antistatic property is grade B.

Namely the production scheme adopted finally: in the industrial silkworm breeding process, when a baby silkworm is 2-4 years old, 15-35 ppm of antibacterial inorganic substance A is added into the food of the baby silkworm, the antibacterial inorganic substance A is eaten for a long time until the baby silkworm spins and cocoons, so that antibacterial raw silk is obtained, and then the antibacterial real silk is prepared by boiling and reeling the silk. Solves the problem of poor antistatic performance of real silk, obviously improves the antibacterial performance and has obvious antibacterial effect.

Example 3

On the basis of the above examples 1 and 2, a method for preparing an antibacterial and antistatic silk-vinegar interwoven fabric is further described.

The preparation method of the antibacterial, antistatic and anti-wrinkle silk and vinegar interwoven fabric comprises the steps that 20-22D antibacterial real silk is adopted as the antibacterial warp yarn 1, and after soaking, silk falling, silk doubling, double twisting, sizing and rewinding are carried out, the larger the wrinkle recovery angle of the fabric is, the better the anti-wrinkle effect is.

The factors influencing the anti-wrinkle effect of the fabric mainly comprise: the density of the yarn, the deformation stress and the recovery performance of the yarn, the tissue structure of the fabric, the thickness of the fabric and the like, so according to the principle that the higher the yarn density of the fabric is, the better the crease-resistant effect is, and meanwhile, in view of saving cost, the density of the antibacterial warp yarn 1 is 500/10-650/10 cm;

the weft 2 is made of 50-75D acetate fibers with the style similar to that of real silk, and is subjected to silk falling, doubling, double twisting and shaping, wherein the number of the back-off count is 400/10-500/10 cm;

referring to fig. 2, the antibacterial, antistatic and crease-resistant silk-vinegar interwoven fabric is manufactured by adopting a five-satin weave manufacturing method with three flyings, the warp direction (gray part) adopts self-made antibacterial and antistatic silk, and the weft direction (white part) adopts acetate fiber for interweaving.

In this embodiment, the antibacterial durability and the antistatic property of the antibacterial antistatic crease-resistant silk-vinegar interwoven fabric are tested by comparison as follows:

table 1 shows the antimicrobial durability test of home-made antimicrobial real silk and common real silk.

As can be seen from the test comparison data in Table 1, the bacteriostatic rate of the home-made antibacterial real silk can reach 92% before washing, which is far beyond the antibacterial requirement of the national standard for textiles, the bacteriostatic rate can still reach 85% after 100 times of washing, which is still higher than the national antibacterial standard for textiles, and the reduction rate of the antibacterial effect is very small in the whole washing process. The bacteriostasis rate of the common white-boiling silk before washing does not meet the national requirement of antibacterial standard on textiles, so the common white-boiling silk after washing can not meet the requirement, and the bacteriostasis effect is reduced rapidly along with the increase of washing times.

Table 2 shows the antibacterial durability test of the antibacterial and antistatic silk-vinegar interwoven fabric and the common silk-vinegar interwoven fabric subjected to the silver ion antibacterial finishing.

As can be seen from the test data in Table 2, the antibacterial rate of the antibacterial, antistatic and crease-resistant silk-vinegar interwoven fabric can reach 85% before being washed with water, and the antibacterial rate of the antibacterial, antistatic and crease-resistant silk-vinegar interwoven fabric exceeds the national antibacterial standard requirement on textiles; the bacteriostasis rate of the antibacterial, antistatic and crease-resistant silk-vinegar interwoven fabric still reaches 82% after 100 times of washing, the reduction rate is very small, and test data also show that the bacteriostasis effect of the antibacterial, antistatic and crease-resistant silk-vinegar interwoven fabric is very reliable. The antibacterial effect of the common silk and vinegar interwoven fabric subjected to silver ion antibacterial finishing is very high and reaches 96% before washing, but the antibacterial rate is greatly reduced along with the increase of the washing times, and is lower than the national antibacterial standard for textiles when the fabric is washed for 50 times, so that the antibacterial effect is obviously reduced.

Table 3 shows the antistatic performance test data of the antibacterial and antistatic silk and the common silk.

According to the national standard GB/T33728-2017, the antistatic half-life period is less than 0.1s, and the antistatic property is A level; the half-life period is less than 5s, and the antistatic property is B grade; the half-life period is less than 60s, and the antistatic property is C. According to the test data in table 3, the antistatic performance of the self-made antibacterial antistatic silk reaches grade B, the half-life periods and the voltages of the three groups of test data are relatively stable and correspond to each other, and as seen from the test process, the antibacterial antistatic anti-wrinkle silk and vinegar interwoven fabric has very small static electricity, so that the problems that the silk is easy to generate static electricity, and the silk is adhered to skin, wrinkles and the like are solved; it can be seen from the test data that in the test of the common real silk, the half-life period of the common real silk obviously exceeds the requirement of B-level antistatic performance, and in the three-group antistatic performance test, the half-life period of the common real silk can reach 43.83s at most, and the antistatic performance can only reach C-level.

In conclusion, in the preparation process of the antibacterial and antistatic silk-vinegar interwoven fabric, the antibacterial effect of real silk is greatly improved from the source of silk production, and the antibacterial, antistatic and anti-wrinkle effects of real silk are really realized through the mixed weaving of the antibacterial and antistatic silk-vinegar interwoven fabric and the acetate fibers.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Therefore, it is within the scope of the present invention to cover all equivalent modifications or changes that can be made by those skilled in the art without departing from the spirit and technical idea of the present invention.
