METHODS AND TOOLING FOR MAKING THREE-DIMENSIONAL SUBSTRATES FOR ABSORBENT ARTICLES
Methods and tooling for making three-dimensional substrates and/or apertured substrates are provided. The three-dimensional substrates and/or apertured substrates may be used in absorbent articles, such as diapers and pants, for example. The methods and tooling may be used on an absorbent article manufacturing line.
LAMINATES FOR ABSORBENT ARTICLES
Three-dimensional laminates and methods for making the same are provided. The three-dimensional laminates may be apertured and may have welds between various substrates. The three-dimensional laminates may be used in absorbent articles, such as diapers and pants, for example, as topsheets, as topsheets and acquisition layers, or as outer cover materials, for example. The three-dimensional laminates may be produced on an absorbent article manufacturing line.

METHOD OF MANUFACTURING BRIDGED ABSORBENT STRUCTURES
A method of manufacturing an absorbent web includes moving a foraminous member in a machine direction. The foraminous member has at least one masking plate with a partitioned area including at least one partition defining a plurality of segments. The method further includes drawing air through the foraminous member and depositing fibrous material onto the foraminous member to form an absorbent web. The absorbent web has a bridged area with a reduced basis weight corresponding to the partitioned area of the masking plate. The bridged area has vertical interfaces separating web segments and fibrous material at least partly bridging the vertical interfaces.
Method Of Forming An Absorbent Structure
A liquid absorbent structure is made by dry laying a fibrous web having incorporated therein a superabsorbent material, and applying an aqueous composite stabilizer to at least one surface of the web. The aqueous composite stabilizer imparts integrity to the resulting structure without substantially impairing the effectiveness of the superabsorbent material to absorb liquid while forming the absorbent structure without removing the water from aqueous composite stabilizer or drying out the absorbent structure. The absorbent composite absorbs the water from the aqueous composite stabilizer. The absorbent composite comprises about 70% by weight of a superabsorbent material.
PROCESS FOR MAKING AN ABSORBENT CORE WITH ADDITIONAL PARTICLE MATERIAL
The present disclosure relates to a process for making an absorbent core comprising a superabsorbent polymer material and an additional particle material.
Systems And Methods Of Applying Compositions To Webs And Webs Thereof
A web having compositions applied thereto is disclosed. The web has a plurality of discontinuities. The composition(s) are associated with the discontinuities and can improve fluid acquisition, rewet and/or fluid masking properties of the web.
TUNABLE SURFACE WETTABILITY OF FIBER BASED MATERIALS
A method for making a permanently wettable material is disclosed. The method includes selecting a plurality of non-polar polymer fibers (12) wherein each fiber has a surface (16), depositing a hydrophilic polymer mixture (14) on the non-polar polymer fiber surface to form a shell. The hydrophilic polymer mixture (14) includes a cross-linkable and graftable epoxy-containing polymer, such as, poly(glycidyl methacrylate-co-ethylene glycol methacrylate) copolymer (PGMA-co-POEGMA), a high weight average molecular weight polyethylene glycol (PEG), and a surfactant. A permanently wettable material is also disclosed that includes a non-polar polymer-based web (10) having fibers (12) with a surface (16). A hydrophilic polymer mixture (14) forms a shell on the non-polar polymer fiber surface (16). The hydrophilic polymer mixture (14) includes a poly(glycidyl methacrylate-co-ethylene glycol methacrylate) copolymer (PGMA-co-POEGMA), a high weight average molecular weight polyethylene glycol (PEG), and a surfactant.
Method and device for feeding granular powder
Provided is a method for feeding a granular powder from a granular powder feeding hopper onto an upper surface of a sheet material. A feeding passage is disposed so as to extend downward from an outlet of the granular powder feeding hopper so that the lower end of the feeding passage faces the upper surface of the sheet material moving beneath the feeding passage. The feeding passage is opened and closed by the open-close means so that the granular powder is intermittently fed from the granular powder feeding hopper onto the sheet material.
