All cotton tampon having high absorption performance and preparation method of all cotton tampon

Abstract

The invention discloses an all cotton tampon having high absorption performance. The tampon body of the tampon includes an absorption body and a wrapping layer covering at least part area of the outer surface of the absorption body; the absorption body is prepared by 100% natural cotton; the absorption body is obtained successively through cotton loosening, carding, lapping, overlapping, composite shaping and cutting by using the natural cotton; and the tooth depth of comb teeth during the carding of the natural cotton is 5-20 mm, the distances between the comb teeth do not exceed 5 mm, single layer cotton fiber is paved at each time during the lapping of the natural cotton, the gram weight of single layer cotton fiber is not less than 10 g / m<2>, and the layers of cotton nets during overlapping are at most 10 layers. The cotton content is the tampon body of the tampon is 100%, and both the use safety and using experience brought for consumers can meet consumer requirements. A feasible technical scheme can be provided for the processing of the tampon.

Description

technical field [0001] The invention relates to the technical field of tampons, in particular to an all-cotton tampon with high absorption performance and a preparation method for the all-cotton tampon. Background technique [0002] The convenience of tampons meets the new needs of consumers. Compared with sanitary napkins, women can freely dress, move, work, exercise, relax, play, etc. without side leakage and worry. It is gradually accepted by domestic consumers, especially young people. When women's menstrual cramps come, tampons can be inserted into the vagina to absorb menstrual blood. They have attracted much attention because of their small size, comfortable and non-sense use, not easy to leak, and excellent absorption capacity. [0003] At present, there are mainly two types of tampons on the market. The first type refers to the push-type tampon, which is inserted into the tampon body through the user's fingers; the second type is the catheter-type tampon. , which ...

AI Technical Summary

Problems solved by technology

However, the length of natural cotton fibers is different, which is not conducive to processing. Therefore, in the process of processing cotton strips, all-natural cotton fibers are rarely used as processing raw materials, and they are more or less compounded with cotton fibers. fiber

This is because in the process of sliver processing, it is necessary to card the viscose fiber or cotton fiber first and then carry out subsequent processing, because the viscose fiber is relatively easy to card into a stable cotton belt with uniform thickness and distribution, while the natural cotton fiber is Its fiber structure characteristics vary widely, such as: fineness, length and curl, etc., so that it cannot be well carded on a special carding machine for tampons, and the cotton tape processed after carding natural cotton fibers The thickness is seriously uneven, which greatly affects the stability of the quality of the tampon, and it is difficult to stably meet the absorption range of the EDANA standard

[0005] Due to the limitation of technical level, the processing level of sliver body using natural cotton fiber is still very backward in China at present. Compression in the thickness direction, then roll forming, and then cutting to form a cotton strip, and then processing the sliver body, so that most of the final sliver body has the problem of too large diameter and too thick sliver body, which seriously affects users. It is more difficult for domestic consumers to accept it, and it is not conducive to publicity and education in the domestic market. Moreover, the thickness of the cotton layer obtained after laying and compressing natural cotton fibers using existing sliver processing equipment makes the processing The stability of the obtained cotton sliver is poor
