Description

Technical Field

[0001] This invention relates to textile manufacturing technology, and more specifically, to a production process for producing microecological crotch sheets using a cylindrical loom and the microecological crotch sheets themselves. Background Technology

[0002] The skin is the body's first line of defense in the immune system. In intact fabric, microorganisms cannot easily invade. The skin's surface is acidic, which normally inhibits the growth of bacteria and fungi. However, when the skin is damaged, infection can occur, leading to various inflammations, skin diseases, and even other illnesses, endangering human health. Therefore, textiles and clothing products, especially those worn next to the skin, must not only be soft and smooth but also free of all toxic and harmful substances.

[0003] The skin's microbiome is similar to other ecosystems, including bacteria, fungi, and viruses. The skin's microecological environment usually includes the microbial environment on the skin's surface and the microclimate environment between the skin and textiles, which is composed of factors such as air, temperature, humidity, pH value, and light. Under normal circumstances, the skin and the microbiome on its surface constitute an interdependent and mutually restrictive ecosystem in a balanced state.

[0004] Due to the unique nature of the genital area, the external microbial environment can affect the body through the genitals. The crotch panel (crotch fabric or gusset) is the part of underwear that comes into direct contact with the genitals, making its microbial system particularly important. Crotch panels on the market are usually made of pure cotton or viscose. The soft texture of pure cotton reduces friction in the genital area, thus preventing...

[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0007] The above-mentioned technical objective of this invention is achieved through the following technical solution: a production process for producing microecological crotch pads using a cylindrical loom, characterized in that its preparation steps include:

[0008] Material preparation: Chitosan fiber, cotton fiber or viscose fiber and microfiber filaments are selected as raw materials according to a weight ratio of 3:4:2. The blended yarn is produced by vortex spinning, drawing, roving and spinning processes. The blended yarn is then oxygen bleached and singeed before it is ready for use.

[0009] For equipment debugging, a 34-inch 24-needle rib circular knitting machine was selected, with the needle arrangement on the lower needle plate being 1212;

[0010] In the yarn feeding process, the blended yarn is placed on the yarn rack and passed through the yarn channel on the rib circular knitting machine in sequence. The yarn is then guided to the corresponding position on the lower needle plate through the needle eye and needle groove. The rib circular knitting machine is then started to weave several blended yarns according to the set knitting structure and knitting boundary to obtain a greige fabric with a tubular structure.

[0011] Monitoring and adjustment: During the yarn feeding and weaving step, monitor the yarn flow of the blended yarn in the yarn channel of the rib circular knitting machine and adjust the yarn feeding speed of the rib circular knitting machine accordingly.

[0012] When the fabric is rolled up and inspected, the fabric is simultaneously expanded by the width-sizing mechanism and then rolled up after the yarn is woven into a tubular structure.

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Example 1: A production process for producing microecological crotch pads using a cylindrical loom, the preparation steps of which include:

[0038] Material preparation: Chitosan fiber, cotton fiber or viscose fiber and microfiber filaments are selected as raw materials according to a weight ratio of 3:4:2. The blended yarn is produced by vortex spinning, drawing, roving and spinning processes. The blended yarn is then oxygen bleached and singeed before use. In this embodiment, the microfiber filaments are polypropylene fiber monofilaments, which are drawn and blended with chitosan fiber, cotton fiber and viscose fiber respectively to form blended yarn A and blended yarn B.

[0039] For equipment debugging, a 34-inch 24-needle circular knitting machine with needles arranged in 1212 on the lower needle plate is selected. Specifically, when feeding yarn, blended yarn A and blended yarn B are fed into the yarn channel of the circular knitting machine in the order of 1212.

[0040] In the yarn feeding process, the winding bobbin containing blended yarn A and blended yarn B is placed on the yarn rack, and blended yarn A and blended yarn B are passed sequentially through the yarn channel on the rib circular knitting machine. The yarn is then guided to the corresponding position on the lower needle plate through the needle eye and needle groove. The rib circular knitting machine is then started, and several blended yarns A and B are woven according to the set knitting structure and knitting boundary to obtain a greige fabric with a tubular structure.

[0041] Monitoring and adjustment: During the yarn feeding and weaving step, the yarn feeding speed of the rib circular knitting machine is adjusted by monitoring the yarn flow of the blended yarn in the yarn channel. In this embodiment, an infrared sensor is installed in the yarn channel of the rib circular knitting machine. The infrared sensor monitors the yarn's obstruction of the sensor and determines whether blended yarn A or blended yarn B has broken, so as to realize the timely shutdown and maintenance of the rib circular knitting machine.

[0042] During the fabric winding and inspection process, when the fabric is woven into a tubular structure, it is simultaneously expanded by a width-lengthening mechanism and then wound up. Specifically, the woven fabric is wound up neatly using the winding roller on the rib circular knitting machine and a U-shaped guide support located above the winding roller. In this embodiment, a flat panel light is installed inside the U-shaped guide support, which illuminates the woven fabric. By illuminating the woven fabric with the flat panel light, an image recognition module can be configured on the rib circular knitting machine to inspect the fabric. This allows for the immediate detection and proactive repair of any defects on the fabric surface.

[0043] Package.

[0044] The specific steps of yarn weaving include:

[0045] For yarn preparation, the winding bobbin containing the blended yarn is placed on a yarn rack, and the blended yarn is fed according to the knitting structure. In this embodiment, the greige fabric is woven with three needle passes on one side, and the pattern of the greige fabric is in eight-way repeats. The third, fourth, and integer multiples of the greige fabric are woven with loop weave, floats, and tuck weave to form breathable holes at intervals in the warp and weft directions of the greige fabric. Specifically, as shown... Figure 1 As shown, the organizational structures of the first, second, fifth, and sixth lines are: circle organization, circle organization, circle organization; the organizational structure of the third line is: clustered circle organization, circle organization, and floating line; the organizational structure of the fourth line is: circle organization, floating line, circle organization; the organizational structure of the seventh line is: circle organization, clustered circle organization, and floating line; and the organizational structure of the eighth line is: floating line, circle organization, circle organization.

[0046] Impregnation involves immersing the blended yarn in a functional impregnation solution before feeding it into the yarn channel. Specifically, a ribbing assembly located at the yarn channel entrance is installed on a circular knitting machine. The impregnation assembly includes a pre-impregnation section and a second impregnation section. A squeezing component is positioned between the pre-impregnation section and the second impregnation section. The squeezing component includes several squeezing units grouped by two rotating rollers 2 or two scrapers. The squeezing units are arranged in a sequential array and located at the feeding inlet of each yarn channel. This allows the functional impregnation solution to fully contact the yarn as it passes through the pre-impregnation section of the ribbing assembly. Then, as blended yarn A and blended yarn B pass through, the squeezing component squeezes the yarn, ensuring that the functional impregnation solution fully penetrates the yarn and squeezing any excess functional impregnation solution back into the pre-impregnation section. Then, when passing through the second impregnation section, the yarn undergoes a second impregnation to increase the impregnation rate. Alternatively, other auxiliaries can be added in the second impregnation section to improve the functionality of the yarn.

[0047] Weaving.

[0048] like Figure 2 and Figure 3 As shown, the padding assembly includes several concentrically arranged liquid storage ring tanks 1. The liquid storage ring tank 1 located on the outer ring contains an antibacterial finishing liquid, while the liquid storage ring tank 1 located on the inner ring contains an antifouling finishing liquid or lubricating silicone oil. The liquid storage ring tank 1 located on the inner ring is equipped with an absorbent sponge. When the blended yarn passes through the yarn channel on the rib circular knitting machine in sequence, the blended yarn passes through the squeezing unit from the liquid storage ring tank 1 on the outer ring, and then comes into contact with the absorbent sponge before being fed into the yarn channel. Specifically, in this embodiment, the functional padding liquid is selected from Zeneca's Reputex20, domestic antibacterial agent FS-516, and antibacterial agent SGJ-963, so that the crotch piece has good antibacterial properties. When the greige fabric is used as the material for the crotch piece, it has good antibacterial and bacteriostatic properties, and plays a role in regulating the microecology of the private parts.

[0049] Example 2: A microecological crotch piece, prepared using the production process of Example 1, wherein the woven fabric is directly heat-set and cut after being tested to obtain the crotch piece.
