Mites are micro-pests that are not easy to see with the naked eye. The bodies, secretions and excrement of mites are allergens, which can cause allergic dermatitis, allergic rhinitis and other diseases; mosquito-borne diseases in my country include malaria, dengue fever, filariasis and other highly harmful infectious diseases; on the other hand, a variety of harmful bacteria, viruses, etc. are everywhere, attacking people and endangering human health all the time. In addition to medical prevention and treatment, textile companies and research institutions around the world are seeking to develop corresponding textiles and functional products through isolation, protection and protection of textiles and clothing.

[0003] At present, the main performances of pure cotton, polyester-cotton varieties and antibacterial and anti-mite products in the market are as follows: First, common pure cotton or polyester-cotton fabrics and ordinary textile fabrics only have the conventional characteristics of moisture absorption, warmth retention or wear resistance, and crispness, and have no other special functions; second, the existing domestic antibacterial, anti-mite and other protective textile products have relatively simple performance and basically do not have multiple functions; third, the processing technology and process of similar fabrics developed at home and abroad are immature, the production process technology of products is not environmentally friendly, and the fabric surface has quality problems such as pilling, poor elasticity, and poor gloss. The comprehensive effect is not ideal, and the functional characteristics given to the product are also limited.

[0067]

[0068] Comparative Example 1

[0069] The difference between the comparative example 1 and the above-mentioned embodiment 1 lies in step S1. The length of the JC40S combed cotton siro-spun yarn used in the comparative example 1 is 31.5CM / 96G / 8R. The fabrics prepared in the comparative example 1 and the embodiment 1 are obviously different in the fabric surface structure and hand feel. Specifically, the fabric surface of the embodiment 1 is flat, with a strong sense of hierarchy and clear and moderate jacquard patterns, while the fabric surface flatness of the comparative example 1 is poor, and the jacquard patterns are loose and not dense; the feel of the embodiment 1 is soft and thick, while the feel of the comparative example 1 is fluffy but not strong enough, and the bursting strength of the grey fabric is slightly lower than that of the embodiment 1. Comparative Example 2

[0070] The difference between the comparative example 2 and the above-mentioned embodiment 1 is that in step S5, 0.8 g / L soaping agent AT-1508 is used in the comparative example 2, and the other process curves are the same. The results of comparing the cloth surface after the post-treatment in step S5 are shown in Table 4. Comparative Example 3

[0071] The difference between the comparative example 3 and the above-mentioned embodiment 1 is that in step S5, the comparative example 3 uses 3g / L soaping agent SC-SA and soaping twice. The process curve is shown in FIG. Figure 4 See Table 4 for the results of comparing the fabric surfaces after post-processing in step S5.

[0072] Compared with comparative example 3, embodiment 1 of the present invention saves a lot of process time and reduces the amount of water used in two cylinders.

[0073] Table 4: Comparison of fabric surface results after post-treatment of Example 1 of the present invention and Comparative Examples 2 and 3:

[0074] Comparative Example 4

[0075] The difference between this comparative example 4 and the above-mentioned embodiment 1 is that in step S4, the dosage of each auxiliary agent is SF-2 1g / L, TF-129K 1g / L, H2O2 6g / L, flake caustic soda 3g / L, neutralizing acid 1g / L, deoxygenase 0.15%, and the process curve is shown in Figure 5 .

[0076] The fabrics prepared in comparative example 4 and examples 1-3 performed similarly in terms of various color fastnesses, all reaching level 4 or above, but the surface effects were significantly different, specifically: the surface of the fabric in example 1 was smooth and free of impurities, had good elasticity, and was soft to the touch; while the surface of the fabric in comparative example 4 was pilling, slightly stiff, had slightly poor elasticity, and had a hard and astringent feel.

[0077] In summary, the yarn selection, singeing process, and specific pre-treatment and polishing / dyeing process control of the present invention have a synergistic relationship for the smoothness and feel of the fabric. In addition, the antibacterial rate of the fabrics prepared in Examples 1-3 of the present invention against Staphylococcus aureus according to FZ / T 73023-2006 is more than 98%, the antibacterial rate of Escherichia coli is more than 98%, and the antibacterial rate of Candida albicans is more than 99%. According to the repellency method test of GB / T 24253-2009, 9.1, the anti-mite repellency rate is more than 90%; according to the repellency method test of GB / T 30126-2013, the anti-mosquito rating is A grade.

[0078] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
