[0002] Antibacterial fabrics are fabrics with good safety. They can effectively and completely remove bacteria, fungi and mold on fabrics, keep fabrics clean, and prevent bacterial regeneration and reproduction. There are two mainstream treatment methods on the market: one is built-in silver ion antibacterial fabrics, which use spinning-level antibacterial technology to directly put antibacterial agents into chemical fibers; the other is post-processing technology, which is to add antibacterial agents through the subsequent shaping process of fabrics.

[0003] These two methods are complex and costly, and as the number of times the fabric is washed increases, the antibacterial agent will be lost rapidly, causing the antibacterial effect to drop rapidly.

[0004] Therefore, a solution needs to be proposed to solve this problem. Summary of the invention

[0011] The present invention is further configured as follows: nano silver is fixed in the inner base fabric by wax.

[0012] The above technical purpose of the present invention is also achieved through the following technical solutions: including a containing mechanism for containing antibacterial dyes, a discharging mechanism connected to the containing mechanism, and a liquid extraction mechanism connected to the discharging mechanism; the containing mechanism, the discharging mechanism, and the liquid extraction mechanism are connected end to end through a conduit; the discharging mechanism includes a discharging seat and a rotating roller rotatably connected to the discharging seat; the discharging seat includes a first water inlet connected to the dye vat, a first water outlet connected to the liquid extraction mechanism, and a water flow channel between the first water inlet and the first water outlet; the rotating roller includes an extension portion extending into the water flow channel; the discharging seat includes a hopper at the upper end; the hopper has a discharge port at the bottom of the hopper; the rotating roller includes a first groove arranged around the circumferential surface of the rotating roller; the discharge port and the first groove are movably connected.

The antibacterial layer includes chitin fiber, polyacrylonitrile fiber and an antibacterial agent. The antibacterial agent includes nanosilver, dodecyl glucoside, glycine and water.

[0023] The antibacterial material is put into a reactor to react and produce an antibacterial liquid, which is then put into a steam box. At the same time, the middle layer of the base fabric passes through the steam in the steam box to inject the antibacterial particles into the antibacterial layer, and then the fan in the steam box is used to cool and shrink it, and the steam in the steam box is used again to inject the antibacterial particles into the antibacterial layer.

[0024] The reinforced antibacterial layer comprises microcapsule mixed yarn with microcapsules; the outer base fabric is a wear-resistant layer, and its material is acrylic fiber and nylon fiber.

[0025] The microcapsule mixed yarn comprises 10% to 15% of chitosan fiber, 30% to 40% of nano silver fiber, 10% to 15% of holy hemp fiber and 30% to 50% of skin-friendly fiber.

[0026] The inner base fabric is cross-woven, the middle base fabric and the outer base fabric are woven by a circular knitting machine, and are connected and fixed by bottom yarn weaving.

[0027] The outer base fabric has a plurality of openings distributed in a matrix, the wool yarn at the openings is cut by a cutter of a circular knitting machine to form plush, the microcapsule mixed yarn is distributed at the openings, and the inner base fabric is adhered to the side surface of the middle base fabric away from the outer base fabric.

[0028] Nano silver is fixed in the inner base fabric by wax.

[0029] The invention comprises a containing mechanism for containing antibacterial dye, a discharging mechanism connected to the containing mechanism, and a liquid extracting mechanism connected to the discharging mechanism; the containing mechanism, the discharging mechanism, and the liquid extracting mechanism are connected end to end through a conduit; the containing mechanism comprises a dye vat for containing dye, a cloth-passing roller in the dye vat, and two guide rollers located on both sides of the cloth-passing roller.

[0030] The material discharge mechanism includes a material discharge seat and a rotating roller rotatably connected to the material discharge seat; the material discharge seat includes a first water inlet connected to the dye vat, a first water outlet connected to the liquid extraction mechanism, and a water flow channel between the first water inlet and the first water outlet; the rotating roller includes an extension portion extending into the water flow channel; the material discharge seat includes a material placement hopper at the upper end; the material placement hopper has a discharge port at the bottom of the material placement hopper; the rotating roller includes a first groove circumferentially arranged on the circumferential surface of the rotating roller; the discharge port and the first groove are movably connected.

[0031] The present invention facilitates contact with the skin through the inner soft layer, and at the same time, the outer base fabric is provided as a wear-resistant layer, which can avoid damage caused by friction in the external environment. The antibacterial layer of the middle base fabric is attached with antibacterial particles, which can ensure long-term antibacterial properties.

[0032] By blending fibers with antibacterial function and then impregnating microcapsule solution, the microcapsules with antibacterial function are carried on the microcapsule mixed yarn, so that the middle-layer base fabric woven from the microcapsule mixed yarn has good antibacterial effect and is washable;

[0033] At the same time, the inner base cloth adheres to the middle base cloth to play a protective role. The middle base cloth and the outer base cloth are woven by a circular knitting machine and connected and fixed by bottom yarn weaving, so that the middle base cloth and the outer base cloth have good integrity, prevent mutual friction between layered materials, and improve processing efficiency.

[0034] The antibacterial dye is placed in the hopper, and the dye liquid in the containing mechanism is extracted through the liquid extraction mechanism. The dye liquid enters from the first water inlet, travels along the water flow channel and impacts the extending part of the rotating roller, so that the rotating roller rotates; when the first groove rotates to be connected with the discharge port, the antibacterial dye in the hopper falls into the first groove; the rotating roller continues to rotate, and when the first groove is in the water flow channel, the antibacterial dye will be integrated into the dye liquid as the dye liquid is flushed, and follow the flow of the dye liquid to flow back into the containing mechanism to supplement the solubility of the dye liquid in the containing mechanism; the antibacterial dye can be effectively supplemented, so that the color of the cloth is uniform during the dyeing process, thereby improving the overall quality of the cloth.
