System and process for preparing a fibrous nonwoven composite fabric
A system having a first polymer source and a spin beam in fluid communication with the first polymer source is provided. The spin beam includes a spinneret assembly having filament nozzles configured and arranged to extrude a plurality of filaments of a first polymer. A gas distribution plate is disposed downstream of the spinneret assembly, and includes a plurality of gas distribution slots that are configured and arranged to receive two or more corresponding filament nozzles of the spinneret assembly therein. A stream of gas is introduced into the plurality of slots to draw and attenuate the filaments extruded by the plurality of filament nozzles. The drawn and attenuated filaments are collected on a collection surface disposed downstream of the gas distribution plate to form a nonwoven fabric. A solid additive, such as pulp fibers may be blended with the filaments prior to collecting the filaments on the collection surface.
Absorbent article with improved performance
An absorbent article having a nonwoven topsheet, a backsheet, an absorbent core disposed therebetween, and a fluid management layer disposed between the topsheet and the absorbent core is disclosed. The fluid management layer is an integrated nonwoven material having a basis weight in a range of from 40 gsm to 75 gsm and has 10 percent to about 60 percent by weight of absorbent fibers, from between about 15 percent to about 70 percent of resilient fibers, and from between about 25 percent to about 70 percent stiffening fibers. The absorbent article exhibits a third dose acquisition time of less than 10 seconds, more preferably less than 8 seconds, and most preferably less than 7 seconds, and a Rewet of no greater than 0.40 g, more preferably less than about 0.3 grams, or most preferably less than about 0.2 grams.
INTIMATE SKIN CONDITIONER VEIL COMPRISING A NONWOVEN MATERIAL
An intimate skin conditioner veil, configured to be positioned in an undergarment so that it covers the mons pubis in front of the anterior labia commissure of a female user, without covering any part of the vulval vestibule area of the user. The main portion may be reflection symmetric about a longitudinal central line, and the veil may include a garment facing layer arranged on a garment facing side of the veil, and a space creating layer arranged on a skin contacting side of the veil. The space creating layer comprises a nonwoven material arranged at least one the skin contacting side of the veil. The nonwoven material includes non-absorbent fibres. The fibres and/or the nonwoven material is/are coated with a lubricating coating composition configured for use in hygiene products at least on the skin contacting side of the veil to be in contact with skin of the user.
POROUS SHEET PRODUCT AND METHODS FOR MAKING AND USING THE SAME
Porous sheet product and methods of making and using the same. In one embodiment, the porous sheet product may be made by a process that includes providing an extrusion mixture, the extrusion mixture including a polymeric binder, a swelling agent, a compatibilizing agent, and a superabsorbent polymer, the superabsorbent polymer being in particle form. The superabsorbent polymer may be wet-milled such that its particle size before and after milling is reduced by a ratio of at least 5:1. The extrusion mixture may be melt-extruded to form a sheet material in film form. At least a portion of the swelling and compatibilizing agents may be removed. The porous sheet product is preferably liquid permeable and may be used, for example, as a battery separator, as a food packaging material, as a diffusion barrier and disposable garments.
ABSORBENT ARTICLE WITH IMPROVED PERFORMANCE
An absorbent article having a nonwoven topsheet, a backsheet, an absorbent core disposed therebetween, and a fluid management layer disposed between the topsheet and the absorbent core is disclosed. The fluid management layer is an integrated nonwoven material having a basis weight in a range of from 40 gsm to 75 gsm and has 10 percent to about 60 percent by weight of absorbent fibers, from between about 15 percent to about 70 percent of resilient fibers, and from between about 25 percent to about 70 percent stiffening fibers. The absorbent article exhibits a third dose acquisition time of less than 10 seconds, more preferably less than 8 seconds, and most preferably less than 7 seconds, and a Rewet of no greater than 0.40 g, more preferably less than about 0.3 grams, or most preferably less than about 0.2 grams.
Absorbent core cover for super-absorbing absorbent cores of sanitary products
The present invention relates to an absorbent core for sanitary products with an absorption matrix which comprises a high proportion of super-absorbing particles, and an absorbent core cover for enveloping the absorption matrix, wherein the absorbent core cover comprises at least one upper side sheet and one bottom side sheet, and the absorbent core cover comprises at least one connection region spaced apart from the edge of the absorbent core in which the upper side sheet and the bottom side sheet are connected to each other. Here, at least the upper side sheet of the absorbent core cover is embodied as a fleece composite with a fixing layer with a low permeability to retain the particles in the absorption matrix, and a transfer layer for acquiring fluid. Moreover, the invention relates to a sanitary product having such an absorbent core, the use of a fleece composite as an absorbent core cover, and a method for manufacturing a fleece composite for the upper side sheet of the absorbent core cover.
Melt blown dressing with gradient density
An absorbable hemostatic nonwoven patch utilizes a biocompatible substrate comprised of melt-blown microfibers as webbed sheets that are layered and bonded/entangled in descending density and ascending porosity; the substrate having a high flexibility, strength and porosity that is suitable for coating cross-linkable active molecules and ability for laparoscopic use or trocar deployment, ultimately for functional use as a highly effective hemostat in addressing problematic bleeding during both open and minimally invasive surgical procedures.
Absorbent article containing nanoporous superabsorbent particles
An absorbent article comprising an absorbent member positioned between a topsheet and a backsheet is provided. The absorbent member contains at least one layer that comprises superabsorbent particles containing nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers.
Napped coated wound dressing
The present invention is directed to an absorbable hemostatic patch that utilizes a biocompatible fibrous, fabric substrate that is melt-blown and napped or loosened at the surface, with the substrate having a low-profile, high flexibility, strength and porosity that is suitable for coating cross-linkable active molecules and ultimately effective for use as a hemostat in situations of problematic bleeding.
NONWOVEN FABRICS INCLUDING RECYCLED POLYPROPYLENE
Nonwoven fabrics are provided that include a first nonwoven layer comprising a first plurality of fine fibers. The first plurality of fine fibers comprises a first polymeric material including (i) a first polymer component and (ii) optionally one or more first additives, wherein the first polymer component comprises a first recycled-polypropylene (rPP) comprising a visbroken spunbond grade polypropylene having a first melt flow rate (MFR) before visbreaking and second MFR after visbreaking, and wherein the second MFR is larger than the first MFR.
