一种天然抑菌棉条制备方法A kind of preparation method of natural antibacterial cotton sliver

技术领域technical field

本发明涉及一次性卫生用品生产领域，尤其涉及一种天然抑菌棉条制备方法。The invention relates to the production field of disposable sanitary products, in particular to a method for preparing a natural antibacterial cotton sliver.

背景技术Background technique

卫生棉条是一种经期卫生用品，可通过与女性***内腔通过接触并吸收月经流来防止月经流出***口，相对于传统的卫生巾，卫生棉条这种内置式的使用方式使得它具备吸收充分不会侧漏、保持***的干净的优点，而且舒适感显著强于具有遮蔽塑料背衬的卫生巾，使用时也不影响衣着和运动。A tampon is a menstrual hygiene product that can prevent menstrual flow from the vaginal opening by contacting the female vaginal cavity and absorbing menstrual flow. Compared with traditional sanitary napkins, the built-in use of tampons makes it capable of It has the advantages of sufficient absorption and no side leakage, keeping the vagina clean, and the comfort is significantly stronger than that of sanitary napkins with a masking plastic backing, and it does not affect clothing and movement during use.

现有的卫生棉条大多采用普通棉纤维制备而成，如公布日为2019年04月26日的中国专利申请201780037499.5公开一种卫生棉条，其包括基本上圆柱形的吸收体，该吸收体被周边压缩并容纳在包装物或施放器中，吸收体由卷起的矩形吸收性材料条带形成，并包括：在卫生棉条***方向上的前端、延伸出移除线的后端、以及侧表面，吸收体的整个外表面，对应于前端、后端和侧表面由吸收性无纺布表层形成。针对卫生棉条在经血量较少的时候难以取出或者与***摩擦引起的不适，该技术方案通过在外侧设置一层吸收性无纺布，可以避免吸收性纤维粘附在***内壁引起的不适，并且可以更滑顺地移除。Existing tampons are mostly prepared from ordinary cotton fibers. For example, Chinese patent application 201780037499.5 published on April 26, 2019 discloses a tampon comprising a substantially cylindrical absorbent body. Compressed peripherally and contained in a pack or applicator, the absorbent body is formed from a rolled up rectangular strip of absorbent material and includes: a front end in the direction of tampon insertion, a rear end extending beyond the removal line, and The side surface, the entire outer surface of the absorbent body, corresponding to the front end, the rear end, and the side surface is formed of an absorbent nonwoven surface layer. Aiming at the discomfort caused by the difficulty in taking out the tampon when the amount of menstrual blood is small or rubbing against the vagina, this technical solution can avoid the discomfort caused by the absorbent fibers adhering to the inner wall of the vagina by setting a layer of absorbent non-woven fabric on the outside. , and can be removed more smoothly.

但是，如上述所述的吸收体由卷起的矩形吸收性材料条带形成，并且吸收体包括吸收芯和吸收性无纺布表层，当吸收性无纺布表层随吸收芯被卷起以形成一柱形吸收体时，吸收性无纺布表层形成了吸收体的整个外表面，完全隐藏了吸收芯的吸收芯纤维，该种结构也使得吸收性无纺布被包覆于吸收芯的中部，吸收性无纺布起到隔层的作用，使得呈柱状的吸收体内的吸收芯的整体性较差，影响液体的内渗速度以及锁水效果，并且传统的卫生棉条为了提高液体的下渗速度通常在其外表面通过热压形成沿其轴向的凹槽，通过该种工艺使得卫生棉条表面的硬度增加，极大的影响使用的舒适性。However, the absorbent body as described above is formed from a rolled up rectangular strip of absorbent material, and the absorbent body includes an absorbent core and an absorbent nonwoven topsheet, when the absorbent nonwoven topsheet is rolled up with the absorbent core to form In the case of a cylindrical absorbent body, the surface layer of the absorbent non-woven fabric forms the entire outer surface of the absorbent body and completely hides the absorbent core fibers of the absorbent core. This structure also enables the absorbent non-woven fabric to be wrapped in the middle of the absorbent core. , the absorbent non-woven fabric acts as a barrier, making the integrity of the absorbent core in the columnar absorbent body poor, affecting the liquid infiltration speed and the water-locking effect, and the traditional tampon is in order to improve the absorption of liquid. The penetration rate is usually formed on the outer surface of the tampon by hot pressing to form grooves along its axial direction. This process increases the hardness of the surface of the tampon, which greatly affects the comfort of use.

并且，卫生棉条这种内置式的结构和使用功能方式也使得其更容易使***形成密闭的无氧缺氧环境，使得厌氧菌出现和大量繁殖，给经期妇女带来不同程度的私处感染和妇科疾病。In addition, the built-in structure and use of tampons also make it easier to form a closed anaerobic and anoxic environment in the vagina, allowing anaerobic bacteria to appear and multiply, bringing different degrees of private parts infection to menstrual women. and gynecological diseases.
