Problems solved by technology

[0003] The surface layer is the part that is in direct contact with the skin, and its material must be soft. The weave and indentation on the surface determine the effect of menstrual blood absorption without rewetting. The inner layer of existing sanitary napkins is mainly cotton, non-woven fabric, pulp or more The high molecular polymer and high molecular polymer composite paper formed by the material composite are used to absorb the outflow of menstrual blood. There are many types of sanitary napkins on the market, but these sanitary napkins can only play the role of absorption and leakage prevention. It has no maintenance effect on women's private parts, and the material of the surface layer cannot be 100% pure cotton. The composite strength between the layers of the existing sanitary napkins is not enough. Therefore, we propose a production method of knitted cloth sanitary napkins

Embodiment 1

[0042] A kind of production method of knitted cloth sanitary napkin, concrete steps are as follows:

[0043] (1) Composite of the two-wing material and the surface layer: spray structural glue on the back of the two-wing material and compound the surface layer, send it to the conveyor belt and wait for it to be compounded with the core body, and the surface layer is pure cotton knitted fabric;

[0044] (2) Composite core and bottom film: first spray structural glue on the bottom film, then fold the core in three, and compound the core with the bottom film that has been sprayed with structural glue through the conveyor belt. The core is absorbent paper. The bottom film is the perforated film;

[0045] (3) Composite core body and surface layer material: send the core body compounded with the base film in step (2) to the next glue spray gun to spray structural glue by the conveyor belt, and process it with step (1) The surface material is compounded, and the structural glue spra...

Abstract

The invention discloses a production method of a knitted cloth sanitary napkin. The specific steps are as follows: composite the two-wing material with the surface layer: spray structural glue on the back of the two-wing material and composite the surface layer, send it to a conveyor belt and wait for it to be composited with the core body, and the surface layer It is pure cotton knitted fabric; the core body is combined with the bottom film: first spray structural glue on the bottom film, and then fold the core body in three. In the production method of a knitted cloth sanitary napkin according to the present invention, each layer is gradually compounded step by step, which increases the composite connection strength of the sanitary napkin, makes the production of the sanitary napkin have a sense of hierarchy, and can increase production efficiency while increasing production efficiency. The composite strength of large sanitary napkins, the surface layer is pure cotton knitted fabric woven with 100% pure cotton JC50S cotton yarn, and through dyeing, finishing and slitting processing to meet the production needs of sanitary napkins, weaving hygienic, no foreign matter, no oil stains 1. The pure cotton knitted fabric without serious defects improves the feeling of using the sanitary napkin in direct contact with the skin, provides a softer surface layer, and is better for people to use.

Description

technical field [0001] The invention relates to the invention of knitted cloth sanitary napkins, improves the traditional processing field of knitted cloth sanitary napkins, and particularly relates to a production method of knitted cloth sanitary napkins. Background technique [0002] Sanitary napkin is a kind of absorbent material, the main material is cotton, non-woven fabric, pulp or polymer composite paper formed by the composite of the above materials, and the side design is mainly used to prevent side leakage , because it will present a certain angle with the tampon body during use, and it is easier to rub against the groin. Therefore, sanitary napkins with soft materials on the side are more popular with women. The back glue of the tampon is made of impermeable material. The menstrual blood is retained in the sanitary napkin to absorb the menstrual blood that flows out of the vagina when a woman's menstrual cramps come; [0003] The surface layer is the part that is...
