Embodiment Construction

[0035] Although the present invention has been described for three-dimensional, porous webs that are particularly suitable for use as the wearer-contacting surface of absorbent moisture-resistant strips such as disposable diapers, sanitary napkins, bandages, etc., The invention is by no means limited to this use. The pattern formed on the mesh can be of any desired shape, regular or random, reticulated or unreticulated, continuous or discontinuous, or any combination of these shapes. The detailed description of the structure described here and its use as a topsheet and / or backsheet on a disposable moisture-absorbing moisture-proof belt makes it easy for those skilled in the art to utilize the present invention to produce a product that can be used in other applications. Mesh used.

Abstract

A soft and elastic mesh with continous 3D macropore pattern is made up of the fluid-impervious plastics. It has the first and the second surfaces, many millpores and many macropores. On said the first surface, there is a joining region and the convex reticular object on the joining region. The small-size volcano-shaped bosses and the volcano-shaped millipores are included in said joining region. Said macropore consisting of wall surface, an opening and a top opening.

Description

[0001] This application is a divisional application of the No. 97182479.7 patent application entitled "Manufacturing Method of a Porous Network" filed on December 15, 1997. technical field [0002] The present invention relates to a method of manufacturing a soft and elastic net, and a soft and elastic net produced by the method. More particularly, the present invention relates to a method of producing a soft and resilient web with a substantially continuous pattern of depressions or holes by means of localized heating. The present invention also relates to a soft and resilient web having a substantially continuous pattern of wells or holes. Background technique [0003] In prior art methods of producing a web such as a formed film, the patterned, porous outer surface of a structure such as an endless belt or drum cylinder surface (referred to herein as forming Surface), set a layer of mesh made of heat-softened film. The vacuum created beneath the forming surface pulls th...
