Liquid permeability clad sheet, manufacturing device thereof and manufacturing method thereof

Abstract

The invention discloses a liquid permeability clad sheet, a manufacturing device of the liquid permeability clad sheet and a manufacturing method of the liquid permeability clad sheet. The liquid permeability clad sheet comprises a first layer sheet and a second layer sheet, the liquid permeability clad sheet is provided with strip-shaped grooves, and cone-shape and three-dimensional openings are formed between the strip-shaped grooves in a horizontal mode. The first layer sheet is bonded with the second layer sheet through the strip-shaped grooves, the cone-shape and three-dimensional openings are provided with flowers hanging on heads, and the flowers hanging on the heads extend towards the lower portion of the second layer sheet. The manufacturing device comprises a punching needle roller, a cooperating roller and a composite punching roller, and heaters are arranged on both the punching needle roller and the composite punching roller. The manufacturing method is adopted by the manufacturing device and carries out the following steps: heating the composite punching roller through the heater, conveying the second layer sheet between the punching needle roller and the cooperating roller to be punched, and conveying the second layer sheet and the first layer sheet between the composite punching roller and the cooperating roller to be punched to composite. By the adoption of the clad sheet, liquid is convenient to seep downwards, the sticky and wet feeling of the skin is reduced, the structure of the manufacturing device is concise in structure and convenient to use, production efficiency of the manufacturing method is good, manufacturing cost is low and effect is good.

Description

technical field [0001] The invention relates to a liquid-permeable composite sheet used in absorbent sanitary products and its manufacturing equipment and manufacturing method, in particular to the modification and compounding of surface layer materials such as diapers and sanitary napkins. Background technique [0002] Absorbent sanitary articles generally consist of a liquid-permeable topsheet, a liquid-impermeable backsheet, and a liquid-absorbent body between the topsheet and the backsheet. Among them, the liquid-permeable surface layer mainly has the following functional requirements: (1) The ability to allow liquid to seep rapidly. (2) The ability to reduce liquid back seepage. (3) Less irritating to skin limbs. In order to increase the liquid permeation rate of the liquid-permeable top sheet, the top sheet of the disposable absorbent article is usually perforated. CN03816801.4 discloses a thermally bonded perforated nonwoven fabric and its manufacturing method. It...

Problems solved by technology

Composite materials made using this aspect can reduce the contact surface with the skin, but the dimple-shaped flaps can hinder the penetration of liquids due to the fusion of fibers at the bond.
