Processing method for increasing stripping resistance of sealed periphery of diaper

Abstract

The invention discloses a processing method for increasing stripping resistance of a sealed periphery of a diaper. The method comprises the following steps of: adding wood pulp cellulose into high polymer water absorbing materials at high proportion; wrapping through ultrathin non-woven fabrics to prepare into a diaper cotton core body; extending four sides of the ultrathin non-woven fabrics into a sealed periphery region of the diaper; spreading hot melting glue on parts of the ultrathin non-woven fabrics in the sealed periphery region of the diaper; gluing; wrapping the diaper cotton core body wrapped by the ultrathin non-woven fabrics through bottom layer non-woven fabrics and surface layer non-woven fabrics up and down; spreading hot melting glue on parts of the bottom layer non-woven fabrics and the surface layer non-woven fabrics, which are located in the sealed periphery region of the diaper, before being wrapped; and under the combined action of extrusion and heat seal of a periphery roller and gluing of hot melting glue, enabling the ultrathin non-woven fabrics in the sealed periphery region of the diaper, and the non-woven fabrics on a bottom layer and a surface layer of the diaper to form a new gluing region, and to be are integrally glued. The invention relates to a diaper manufacturing method, which conforms to industry development, is natural resource -saving, and meets the requirements on manufacturing the light and thin diaper cotton core body through the high polymer water absorbing materials at high proportion.

Description

Technical field: [0001] The invention relates to the technical field of personal hygiene products, in particular to a processing method for increasing the anti-peeling force of the diaper seal, which is to change the wrapping material and wrapping method of the cotton core body during the production process of the diaper to increase the wrapping force of the diaper. A new fabrication method for sealing against peeling force. technical background: [0002] The known diaper cotton core is made of wood pulp fiber added with polymer water-absorbing material, wrapped and pressed by toilet paper, the outside of the diaper cotton core is wrapped by non-woven fabric, and the diaper cotton core is surrounded by a pair of peripheral seals. Two layers of non-woven fabrics are pressed by rollers, bonded by sizing, heated and heat-sealed to form a diaper cover. If the two layers of non-woven fabrics around the back cover and the surface of the diaper are separated, a relatively large fo...

AI Technical Summary

Problems solved by technology

But there will be follow-up problems: the diaper seal made by the traditional production process cannot lock the cotton core of the diaper after it absorbs liquid due to its small peeling force

However, if you simply increase the amount of glue applied around the diaper seal, too much glue will seep out and stick to the bottom and surface of the diaper product.
