Description

Technical Field

[0001] The invention relates to the technical field of menstrual physiological underwear, and in particular to a menstrual physiological underwear fabric and a manufacturing process thereof. Background Art

[0002] Menstruation refers to the duration of each menstrual period for women, which is generally 2-7 days, and most of the time 3-5 days. Generally, women's menstruation lasts from their teens to their fifties, and they spend a lot of time in their menstrual period in their lives. Women have a variety of choices for sanitary products during their menstrual period, among which sanitary napkins and menstrual physiological underwear are the most common. Menstrual physiological underwear can also be called pant-type sanitary napkins. Due to its good wrapping and leak-proof properties, it is usually used at night. With the popularity of menstrual physiological underwear, in life scenarios where sanitary napkins cannot be replaced in time, many users choose to use menstrual physiological underwear during the day, and people with heavy menstrual blood volume also use menstrual physiological underwear during the day.

[0003] Ordinary menstrual underwear is not good enough in moisture absorption, waterproof and leakage prevention, and is easy to leak or penetrate, making women's pants or bedding dirty, which is not only embarrassing but also difficult to clean, affecting sleep, and is not conducive to menstrual physical and mental health. Most of them are disposable and cannot be recycled, which puts great pressure on the environment and is contrary to the concept of sustainable development. Or some menstrual underwear is good in moisture absorption, waterproof and leakage prevention, but because the inner layer of the pants body crotch is made of multiple layers of overlapping fabrics, and the multiple layers of fabrics are not connected together, only the edges are fixed by cutting, the pants body crotch is too thick, not breathable, not comfortable to wear, and does not have antibacterial function. Menstruation is a period when women's immunity is low. If the underwear does not have antibacterial function, it is easy to breed bacteria, leading to the occurrence of gynecological diseases, posing a potential threat to women's health.

[0039] See also Figure 1, an embodiment of the present invention provides a menstrual physiological underwear fabric, which is mainly used in the inner layer of the crotch of menstrual physiological underwear. The menstrual physiological underwear fabric includes a first bamboo fiber terry cloth 1, a second bamboo fiber terry cloth 2 and a TPU mid-permeable film 3, the second bamboo fiber terry cloth 2 is pasted on the back of the first bamboo fiber terry cloth 1, the TPU mid-permeable film 3 is pasted on the back of the second bamboo fiber terry cloth 2, the first bamboo fiber terry cloth 1 is evenly soaked with an antifungal and antibacterial agent, and the second bamboo fiber terry cloth 2 is evenly soaked with an antifungal and antibacterial agent, and the antifungal and antibacterial agent adopts an American Dow Corning antibacterial finishing agent. The menstrual physiological underwear fabric of the present invention has a simple structure, only three layers, a soft overall texture, a good body feel, good moisture permeability, moisture absorption and leakage-proof performance, antibacterial and odor removal, and can be recycled. The specific analysis is as follows:

[0040] 1) Double-layer bamboo fiber terry cloth is used to absorb moisture in layers, which has a large moisture absorption capacity. The bamboo fiber terry cloth is soft and comfortable, environmentally friendly, has good moisture permeability and air permeability, and also has very good natural antibacterial effect;

[0041] 2) Since the first bamboo fiber towel cloth 1 and the second bamboo fiber towel are also evenly soaked with the anti-mildew and antibacterial agent, the menstrual physiological underwear cloth has excellent antibacterial effect, meets the standard of "Antibacterial Textiles" T / GDBX 056-2022AAAAA level, and has a certain odor removal effect;

[0042] 3) Ordinary menstrual underwear on the market is often coated with a layer of PU glue for waterproof and penetration prevention, but it is not permeable, easy to crack, and not easy to degrade. The present invention uses a food-grade TPU medium permeable membrane 3, which has excellent moisture permeability, waterproof and anti-leakage, safety, environmental protection, and degradability. The moisture permeability is greater than 2500g / (m 2 24h), and it is not easy to crack when cleaning;

[0043] 4) Since the first bamboo fiber towel cloth 1, the second bamboo fiber towel cloth 2 and the TPU middle transparent film 3 are pasted together, it can not only avoid damaging the TPU middle transparent film 3 during washing, but also improve the overall comfort and feel good;

[0044] 5) The comfort of menstrual underwear made of the menstrual underwear fabric will be greatly improved, the leakage prevention effect will be better, and the wearer will be able to stay dry and comfortable even during menstruation, with a better experience and avoid social embarrassment;

[0045] 6) The moisture absorption capacity of the menstrual physiological underwear made of the menstrual physiological underwear fabric is between 15 ml and 85 ml, which fully meets the moisture absorption requirements of the user during the menstrual period, and can reduce the amount of menstrual physiological underwear used during the menstrual period, which is in line with the concept of environmental protection.

[0046] In this embodiment, the front side of the first bamboo fiber terry cloth 1 is a terry surface, and the back side of the first bamboo fiber terry cloth 1 is a base surface; the front side of the second bamboo fiber terry cloth 2 is a terry surface, and the back side of the second bamboo fiber terry cloth 2 is a base surface; the terry surface of the second bamboo fiber terry cloth 2 is attached to the base surface of the first bamboo fiber terry cloth 1, and the TPU medium permeable film 3 is attached to the base surface of the second bamboo fiber terry cloth 2. The terry surfaces of the first bamboo fiber terry cloth 1 and the second bamboo fiber terry cloth 2 can quickly absorb and lock liquid to keep the wearer dry. The base surface of the first bamboo fiber terry cloth 1 is relatively flat, providing a good contact surface for attachment to the second bamboo fiber terry cloth 2. The base surface of the second bamboo fiber terry cloth 2 is relatively flat, providing a good contact surface for attachment to the TPU medium permeable film 3.

[0047] Of course, in other embodiments, the front side of the first bamboo fiber terry cloth 1 may also be the base side, and the back side of the first bamboo fiber terry cloth 1 may also be the loop side; the front side of the second bamboo fiber terry cloth 2 is the loop side, and the back side of the second bamboo fiber terry cloth 2 is the base side, and the loop side of the second bamboo fiber terry cloth 2 is attached to the loop side of the first bamboo fiber terry cloth 1, and the TPU middle permeable film 3 is attached to the base side of the second bamboo fiber terry cloth 2. Alternatively, the front side of the second bamboo fiber terry cloth 2 is the base side, and the back side of the second bamboo fiber terry cloth 2 is the loop side, and the base side of the second bamboo fiber terry cloth 2 is attached to the loop side of the first bamboo fiber terry cloth 1, and the TPU middle permeable film 3 is attached to the loop side of the second bamboo fiber terry cloth 2, and the present invention does not limit this.

[0048] In this embodiment, the overall thickness of the menstrual physiological underwear fabric is about 1.5-2.2mm. This thickness range ensures that the fabric is neither too thick to cause discomfort to wear, nor too thin to lack the necessary moisture absorption and anti-leakage functions, and at the same time enables it to withstand the test of daily use and washing. Among them, the thickness of the first bamboo fiber terry cloth 1 and the second bamboo fiber terry cloth 2 are both about 0.75-1.1mm. This thickness range ensures that the first bamboo fiber terry cloth 1 and the second bamboo fiber terry cloth 2 can fully absorb and lock the normal menstrual volume of women and keep the wearer dry. In addition, this thickness makes the fabric softer and improves the comfort of wearing. The thickness of the TPU mid-permeable membrane 3 is about 0.012-0.025mm, which can ensure the overall softness of the fabric. Although this thickness range is very thin, the TPU mid-permeable membrane 3 can still effectively prevent liquid penetration, and the moisture permeability is greater than 2500g / (m 2 · 24h), allowing moisture to escape from the TPU through the membrane 3, maintaining the wearer's comfort.

[0049] In this embodiment, the second bamboo fiber towel cloth 2 is pasted on the back of the first bamboo fiber towel cloth 1 by environmentally friendly glue and a grid-shaped polymer dispensing process, and the TPU medium permeable film 3 is pasted on the back of the second bamboo fiber towel cloth 2 by environmentally friendly glue and a grid-shaped polymer dispensing process. The use of a grid-shaped polymer dispensing process allows the environmentally friendly glue to be applied only on specific points or lines, rather than covering the entire surface, thereby ensuring that the second bamboo fiber towel cloth 2 can be firmly pasted on the back of the first bamboo fiber towel cloth 1, and the TPU medium permeable film 3 can be firmly pasted on the back of the second bamboo fiber towel cloth 2, and can greatly reduce the area that hinders moisture penetration, allowing moisture to pass through the cloth more effectively, improving the permeability of the menstrual physiological underwear cloth, and making the wearer feel more comfortable, especially when the humidity needs to be better managed during the menstrual period. In addition, compared with the method of applying glue all over, the grid-shaped dispensing reduces the amount of environmentally friendly glue used, making the overall cloth thinner and lighter, while also maintaining better flexibility and improving the comfort of wearing.

[0050] See also Figure 2 The manufacturing process of the menstrual physiological underwear fabric of the present invention comprises the following steps:

[0051] Step S0, cutting the first bamboo fiber terry cloth 1, the second bamboo fiber terry cloth 2 and the TPU middle transparent film 3 so that the sizes of the first bamboo fiber terry cloth 1, the second bamboo fiber terry cloth 2 and the TPU middle transparent film 3 remain consistent, and strictly controlling the dimensional accuracy of the three during the cutting process to ensure that the subsequent processes proceed smoothly and meet the dimensional requirements of the grid-shaped polymer dispensing process.

[0052] Step S1, the front side of the second bamboo fiber towel cloth 2 is adhered to the back side of the first bamboo fiber towel cloth 1 by a grid-shaped polymer dispensing process to form a double-layer bamboo fiber towel cloth. The grid-shaped polymer dispensing process reduces the amount of glue used, ensures the bonding strength and maintains good permeability, and the double-layer structure enhances the moisture absorption capacity and durability of the underwear.

[0053] Specifically, step S1 includes the following sub-steps:

[0054] Step S11, using a grid-shaped polymer glue dispensing process, evenly coating the back of the first bamboo fiber towel cloth 1 with polymer environmentally friendly glue to form a grid-shaped pattern;

[0055] Step S12, placing the second bamboo fiber towel cloth 2 with the front side facing downward and accurately aligned on the back side of the first bamboo fiber towel cloth 1 coated with glue;

[0056] Step S13: The glue is quickly cured by heating or pressurizing to firmly combine the first bamboo fiber terry cloth 1 and the second bamboo fiber terry cloth 2 together to form a double-layer bamboo fiber terry cloth.

[0057] Step S2, the TPU medium permeable film 3 is pasted on the back of the double-layer bamboo fiber towel cloth by a grid-shaped polymer dispensing process to form a menstrual physiological underwear cloth. The addition of the TPU film effectively prevents menstrual blood leakage, while maintaining excellent moisture permeability (moisture permeability refers to the performance of water passing through the cloth in the form of steam), reducing the sense of dampness, and making the wearer feel more comfortable. At the same time, the use of the grid-shaped polymer dispensing process can ensure that the TPU medium permeable film 3 can be firmly pasted on the back of the double-layer bamboo fiber towel cloth, and can greatly reduce the area that hinders moisture penetration, allowing moisture to pass through the cloth more effectively.

[0058] Specifically, step S2 includes the following sub-steps:

[0059] Step S21, using a grid-shaped polymer glue dispensing process, evenly coating the back side of the double-layer bamboo fiber terry cloth (i.e., the back side of the second bamboo fiber terry cloth 2) with polymer environmentally friendly glue to form a grid-shaped pattern;

[0060] Step S22, place the TPU transparent film 3 with one side facing downward, and after precise alignment, place it on the back of the double-layer bamboo fiber towel cloth coated with glue;

[0061] Step S23: The glue is rapidly cured by heating or pressurizing, and the TPU medium-permeable membrane 3 and the double-layer bamboo fiber towel cloth are firmly combined together to form the menstrual physiological underwear cloth.

[0062] Step S3, soaking the menstrual physiological underwear fabric in an anti-mildew and antibacterial agent, which uses the American Dow Corning antibacterial finishing agent, so that the anti-mildew and antibacterial agent can fully penetrate into the fibers of the first bamboo fiber towel cloth 1 and the second bamboo fiber towel; the menstrual physiological underwear fabric has excellent antibacterial properties after the anti-mildew and antibacterial treatment, and can inhibit the growth and reproduction of microorganisms such as bacteria, thereby effectively removing odors caused by bacteria and other microorganisms.

[0063] Specifically, step S3 includes the following sub-steps:

[0064] Step S31, prepare an appropriate amount of antifungal and antibacterial agent, ensuring that the concentration is moderate, which can effectively kill bacteria and avoid damage to the fabric;

[0065] Step S32: completely immerse the entire menstrual underwear fabric in the anti-mildew and anti-bacterial agent to ensure that every inch of the fabric is in full contact with the anti-mildew and anti-bacterial agent.

[0066] Step S33, keep soaking for a period of time to allow the mildew and antibacterial agent to fully penetrate into the fibers of the first bamboo fiber towel cloth 1 and the second bamboo fiber towel.

[0067] Step S4, drying or air-drying the soaked menstrual underwear fabric to form the final menstrual underwear fabric. Drying can quickly remove moisture and shorten the production cycle, but attention should be paid to temperature control to protect the fabric quality. Although natural air-drying takes a long time, it is more environmentally friendly and can retain the natural characteristics of the fabric to a certain extent.

[0068] Through the above-mentioned production process of menstrual physiological underwear fabric, not only the comfort, moisture absorption, moisture permeability, anti-penetration and antibacterial properties of menstrual physiological underwear are improved, but also the durability and environmental protection of the product are ensured, providing female consumers with a better choice.

[0069] It should be noted that the order of step S1 and step S2 can be interchanged, and the present invention does not impose any limitation on this.
