Absorptive article and manufacturing method thereof

Abstract

The invention discloses an absorptive article. The absorptive article is provided with an outer wrapping layer and an inner core arranged on the inner side of the outer wrapping layer, wherein the outer wrapping layer is formed by a sheet which has the elasticity both in the longitudinal direction and in the transverse direction. The invention further discloses a manufacturing method of the absorptive article. The manufacturing method comprises a process of making the sheet with the elasticity into the outer wrapping layer and a process of configuring the inner core to the outer wrapping layer, wherein the stretching ratio of the outer wrapping layer is controlled to be 1-1.5 in the process. According to the absorptive article and the manufacturing method thereof, through the sheet with the elasticity, the outer wrapping layer made of the sheet achieves the elasticity without additionally adding elastic materials, therefore, a large quantity of elastic materials, an elastic material adding device, a gluing device and an inner core steering device are omitted, and then the purposes of achieving a simple structure and reducing cost are achieved.

Description

technical field [0001] The invention belongs to the field of sanitary products, in particular to a disposable absorbent product and a manufacturing method thereof. Background technique [0002] A conventional disposable absorbent article is known that includes both side sheets for preventing side leakage of liquid, an absorbent main body for absorbing and retaining liquid, and a back sheet for preventing liquid penetration. In order to enhance the fit of absorbent articles to the body, there has been an improved method of adding elastic waistlines to the front and rear ends of the product interior formed by the sheets on both sides, the absorbent main body, and the back sheet, that is, to form a panty-type diaper . In addition, there is another method, which is to add elastic waist elastic members and leg arc elastic members between two layers of covering materials, and add the formed interior to the covering materials to form a panty-style underwear. Diapers. [0003] At...

Problems solved by technology

However, the elastic folds formed by the above method feel hard and not soft enough. At the same time, the folds and creases produced by the stretching of the elastic material cannot be closely attached to the skin, and it is easy to draw red marks on the skin of the user, especially for babies. The skin can cause some damage, resulting in a decrease in comfort

[0004] In addition, because the traditional outer covering layer itself does not have elasticity, if you want to give the outer covering layer elasticity at the waist, you need to add additional elastic materials and fix it with hot melt adhesive, so it is necessary to increase the elastic adding device and glue machine. On the one hand It will lead to an increase in manufacturing costs and a reduction in production efficiency. On the other hand, it will increase the floor area of ​​the production line, which is not conducive to space layout
