Description

High-moisture-retention tampon and preparation method thereof

Technical Field

The invention relates to the technical field of sanitary products, in particular to a high-moisture-retention sanitary cotton sliver and a preparation method thereof.

Background

The cotton sliver is a cotton cylinder and is mainly made of cotton, artificial fiber or a mixture of the cotton and the artificial fiber, cotton threads (pull ropes) are attached to the tail end of the cotton sliver, and the cotton sliver can be placed into the vagina to absorb menstrual blood when female menstrual blood is flushed. The convenience of the sanitary cotton strip meets the demands of consumers, and compared with the sanitary towel, the sanitary cotton strip can be freely worn, moved, worked, moved, casued, played and the like, is not bitter of side leakage and worry, is being accepted by domestic consumers gradually, and is especially popular with young people.

However, most tampons on the market at present are tampons, and friction is generated between the tampons and the inner wall of the vagina when the tampons are used, so that the irritation to the vaginal mucosa is increased. The vaginal mucosa has a protective effect, so that the vagina can keep a weak acid environment, a sterilization effect is achieved, and once the vagina is damaged, inflammation can occur. Tampons on the market are not suitable for long-term use by women suffering from vaginal inflammation.

In view of the deficiencies of the prior art, it is desirable to provide a highly moisturizing tampon that addresses the above-described problems.

Disclosure of Invention

The invention aims to provide a high-moisture-retention sanitary cotton sliver and a preparation method thereof, wherein an elastic moisture-retention layer is wrapped outside a cotton sliver body, so that friction between the cotton sliver and the inner wall of a vagina is reduced, the elastic cotton has good flexibility, is more attached and soft, and moisture retention effect of moisture retention liquid penetrating fibers is better.

In order to achieve the above object, the present invention provides a high moisture retention tampon comprising a tampon body and a moisture retention layer wrapped outside the tampon body; the moisturizing layer is elastic cotton soaked with moisturizing liquid, and the moisturizing liquid comprises the following components in percentage by mass: 1 to 5 percent of olive oil, 1 to 3 percent of olive oil emulsifier, 1 to 5 percent of sweet almond oil, 1 to 4 percent of caprylic-capric glyceride, 0.01 to 0.1 percent of hyaluronic acid, 1 to 5 percent of aloe, 1 to 4 percent of glycerol, 1 to 5 percent of propylene glycol and the balance of water.

The elastic cotton has the skin-friendly and moisture-absorbing capacity of cotton, has flexibility, can also improve the wetting quantity and the moisture-preserving capacity of the moisture-preserving liquid, further improves the time for the cotton to play a role in preserving moisture, and effectively reduces the friction between cotton sliver and the inner wall of vagina.

Further, the infiltration amount of the moisturizing liquid is 5-15% of the mass of the elastic cotton. The proper infiltration amount can not only play a good role in keeping moisture and sliding, but also prevent the absorption problem of menstrual blood from being influenced by excessive infiltration.

Further, the elastic cotton consists of 80-98% of cotton fibers and 2-20% of polyurethane fibers. Further, the elastic cotton consists of 88-95% of cotton fibers and 5-12% of polyurethane fibers. Through reasonable control of the content of polyurethane fibers, the hygroscopicity and elasticity of the elastic cotton achieve comprehensive optimal effects, not only can the infiltration amount of the moisturizing liquid be ensured, but also the water locking effect can be improved by utilizing the elastic fibers, and the loss of active ingredients is prevented, so that the long-acting moisturizing and sliding effect is ensured. The elasticity also contributes to the expansion of the tampon body, reducing the binding force to the tampon body.

Further, the elastic cotton has a strip-shaped fold structure for improving the expansion degree thereof, and also contributes to the expansion of the cotton sliver body, preventing the liquid absorption from being affected by binding.

Further, the wrapping area of the elastic cotton accounts for 10-100% of the lateral surface area of the cotton sliver main body, and preferably accounts for 50-80%; by the arrangement, the liquid absorbing effect of the cotton sliver main body can be improved by utilizing the exposed part.

Further, the gram weight of the elastic cotton is 30-60 g/m ², and the thickness is 0.1-0.8 mm.

Further, the diameter of the cotton sliver main body is 5-15 mm, the tail part of the cotton sliver main body is provided with a stay wire, and the length of the stay wire is 30-120 mm.

Further, the moisturizing liquid comprises the following components in percentage by mass: 3% of olive oil, 1.5% of olive oil emulsifier, 3% of sweet almond oil, 2% of caprylic-capric acid glyceride, 0.05% of hyaluronic acid, 3% of aloe, 2% of glycerol, 3% of propylene glycol and 82.45% of water. The components have the following functions:

Olive oil: the skin is compatible, the absorption is rapid, the dryness is relieved, and the elasticity and the moisturizing of the skin are effectively maintained.

Olive oil emulsifier: long-acting moisture retention, excellent skin affinity, easy absorption, excellent moisture retention capability and capability of enhancing the elasticity and lubricity of the skin.

Sweet almond oil: has good skin friendliness, is moist, is suitable for sensitive skin, softens skin, and can relieve itching, redness and swelling, dryness and inflammation.

Caprylic-capric acid glyceride: has effects in making skin smooth and not greasy, and keeping skin smooth and glossy.

Hyaluronic acid: special water-retaining effect, smoothness, moisture retention and elasticity increase.

Aloe: moisturizing, anti-inflammatory and inflammation relieving.

Glycerol: lubrication and moisture retention.

Propylene glycol: moistening and moisturizing.

The preparation method of the high-moisture-retention tampon according to any one of the above steps, preparing a moisture retention liquid according to mass, soaking elastic cotton in the moisture retention liquid, taking out, wrapping outside a tampon main body, and then sealing in a sealing bag to obtain the high-moisture-retention tampon.

Further, the elastic cotton is soaked in the moisture retention liquid after being stretched, the elastic cotton is taken out and then returns to the original state after the tension is released, and then the elastic cotton is wrapped outside the cotton sliver main body in a strip-shaped fold structure;

The stretching elongation multiple is 1.1-1.5 times, and the strip-shaped fold structures are distributed along the length direction of the cotton sliver main body. In such an operation, the elastic cotton is stretched to absorb the moisturizing liquid more easily, the absorption speed is higher, the tension is released after infiltration, and the moisturizing liquid is tightly locked between the fibers under the action of resilience force, so that the moisturizing capability of the elastic cotton can be improved.

The beneficial effects of the invention are as follows:

1. according to the high-moisture-retention sanitary cotton sliver provided by the invention, the elastic moisture retention layer is wrapped outside the cotton sliver body, so that the friction between the cotton sliver and the inner wall of the vagina is reduced, the elastic cotton has good flexibility, is more fit and soft, the moisture retention effect of the moisture retention liquid penetrating the fiber is better, and the moist appearance can reduce the friction between the cotton sliver and the inner wall of the vagina, so that the irritation to the mucous membrane of the vagina is reduced, and the risk of damage is reduced.

2. According to the invention, the elastic cotton is preferably soaked in the moisturizing liquid after being stretched, so that the soaking speed can be increased, the soaking quantity is increased, the tension is released after soaking, the moisturizing liquid is tightly locked between the fibers under the action of resilience force, and the moisturizing capability of the moisturizing liquid can be improved.
