Technical Field

The invention relates to the technical field of tampons, in particular to a preparation method of a functional tampon and the functional tampon.

Background

Tampons currently on the market are relatively single, and most tampons have been developed for the absorption of menstrual blood. The reason for this is that the sanitary napkin is easy to spray functional liquid medicine on the surface layer during production, and the sanitary napkin is easy to be provided with the surface layer non-woven fabric with functional effect on the surface, so the surface layer with functional effect can directly contact with the skin, thereby the best effect of functional substances is exerted, however, the tampon is a compact cylindrical product with bullet head top end obtained by compressing the cotton belt layer, and is limited by the limitation of the shape and size, and different functional effects are difficult to be realized by simply spraying the functional liquid medicine on the surface of the tampon, therefore, the production of the tampon with functional effect is still a difficult problem in the industry.

At present, most tampons produced in the industry need a layer of hydrophobic hot-rolled non-woven fabric on the surface layer of the tampon in order to facilitate the formation of the tampon by heat bonding of the head end and the tail end of a cotton roll. The existing preparation method of the functional tampon generally comprises the following three methods: spraying the functional liquid medicine on the surface of a semi-finished cotton strip of the tampon, spraying the functional liquid medicine on the surface of a surface layer non-woven fabric layer and directly spraying the functional liquid medicine on the surface of the tampon which is formed by compression.

If the functional liquid medicine is sprayed on the surface of the semi-finished product cotton belt, a large amount of liquid medicine needs to be sprayed to ensure that the liquid medicine adsorbed on the semi-finished product cotton belt can be fully released and contacted with the skin of a human body to play a corresponding effect when in use, and the liquid medicine on the surface of the cotton belt is difficult to be uniformly distributed, so that the processing cost of the functional tampon is high, the liquid medicine components on the surface of the tampon are also uneven, and the expected functional effect is difficult to realize.

If the functional liquid medicine is sprayed on the surface of the surface layer non-woven fabric layer, the hot-rolled non-woven fabric is prepared from the PE/PET material, so that the liquid absorption amount is small, and the finally obtained tampon is difficult to absorb sufficient liquid medicine, so that the tampon is difficult to exert corresponding effect.

If the liquid medicine is directly sprayed on the surface of the compression-molded tampon, the tampon can expand and become soft and thick due to moisture absorption, and even the strength of the tampon is easily reduced and the tampon is easily scattered, so that the quality of the tampon and the use experience of consumers are seriously influenced.

Disclosure of Invention

To overcome the above disadvantages, it is an object of the present invention to provide a method for preparing a functional tampon. The functional tampon prepared by the method not only has high liquid medicine dispersion uniformity, but also can obviously reduce the usage amount of the liquid medicine and exert the optimal effect of the liquid medicine, and the production efficiency of the functional tampon can be improved by the method.

The preparation method of the functional tampon of the present invention comprises the following steps:

step 1: carding the first cotton belt: pre-wetting the formed cotton fibers by using a functional liquid medicine and carding to obtain a first cotton belt;

step 2: carding the second cotton belt: preparing a second cotton belt by carding the finished cotton fibers;

and step 3: pressing the first cotton belt and the second cotton belt to prepare a semi-finished cotton belt;

and 4, step 4: a layer of non-woven fabric is bonded on one side, opposite to the side provided with the second cotton belt, of the first cotton belt;

and 5: winding a pull rope on the semi-finished product cotton belt obtained in the step 4, placing a non-woven fabric layer on the outer layer, hot-pressing the semi-finished product into a roll to obtain the functional tampon,

the grammage of the first cotton belt is less than the grammage of the second cotton belt.

The method can greatly reduce the usage amount of the liquid medicine and ensure that the liquid medicine has the best use efficiency, and the functional liquid medicine in the functional tampon prepared by the method of the invention is uniformly dispersed and can quickly penetrate through the hot-rolled non-woven fabric and contact with the skin to exert the effect.

Further, the cotton-forming fibers are selected from at least one of cotton-forming fibers, cotton fibers or cellulose fluff pulp fibers.

Further, step 1 and step 2 are performed simultaneously.

Further, the content of the functional liquid medicine in the cotton-forming fiber subjected to the pre-wetting treatment in the step 1 is not more than 20%.

Further, the functional liquid medicine is at least one selected from the group consisting of a traditional Chinese medicine liquid, a biological enzyme and a probiotic.

Further, the gram weight of the first cotton belt is 0.1-2.0 g/m, the thickness is 0.01-1.0 mm, and the width is 10-60 mm.

The second purpose of the invention is to provide a functional tampon, which is sequentially provided with a first cotton tape layer and a second cotton tape layer from outside to inside, wherein the gram weight of the first cotton tape layer is smaller than that of the second cotton tape layer, and the first cotton tape layer is prepared by combing cotton-forming fibers subjected to functional liquid medicine pre-wetting treatment.

Furthermore, a non-woven fabric layer is arranged on the outer surface of the first cotton tape layer.

The functional liquid medicine in the functional tampon is uniformly dispersed and can quickly penetrate through the hot-rolled non-woven fabric on the surface of the tampon to contact with the skin to exert the effect. The functional liquid medicine of the tampon is directly combined with the cotton forming fiber and added in the processing process of the cotton belt, so that the cotton belt obtained after carding is uniformly distributed, and the tampon cannot expand, become soft and become thick due to the absorption of water in the liquid medicine. In addition, the liquid medicine in the tampon is arranged on the first tampon layer close to the outer surface of the tampon, so that the tampon can be ensured to achieve corresponding use efficacy on the premise of reducing the use amount of the liquid medicine as much as possible.
