20240148568 · 2024-05-09 ·

A tackifier-free, hot melt adhesive composition comprises an amorphous, single site-catalyzed, high molecular weight propylene copolymer, preferably with a weight average molecular weight (M.sub.w) greater than 80,000 g/mol; a semicrystalline, single site-catalyzed, low molecular weight propylene copolymer, preferably with an M.sub.w less than 60,000 g/mol; and polyisobutene. The composition may optionally include a plasticizer, a butene-rich copolymer, and an antioxidant. The hot melt adhesive is especially useful for bonding substrates which swell or elongate significantly in use. Such uses include adhering superabsorbent polymers to a substrate or adhering together two substrates, at least one of which has superabsorbent polymers, such as the layers of an absorbent core of a disposable hygiene article, such as a diaper. The composition, which does not contain a tackifier, demonstrates suitable elongation at break, stress retention, and thermal stability, making it well-suited for stabilizing expanded species such as superabsorbent polymers.

WOMAN SANITARY FLUID CAPTURE SYSTEM
20190231609 · 2019-08-01 ·

A sanitary fluid capture system allows for better fluid transfer to an absorbent pad. The system places moisture capturing and transferring materials in contact with the source of the fluids. Absorbent material forms a basin to capture excess fluid flow while it is sequestered by the absorbent materials.

Absorbent article

A disposable diaper whose absorber body changes its shape to motion of the wearer for enhanced fitting and wearing comfort, without excessively increased rigidity, includes an absorbent element having an absorber body and a wrapping sheet, and provided on its body side round and oval compressed areas, respectively. The round areas includes first and second compressed areas arranged respectively at intervals in the width and front-back directions, the second areas shifted from the first areas by half the intervals in the width and frond-back directions, the oval areas includes first compressed areas arranged between adjacent first round areas and between adjacent second round areas, with its major axis being aligned to the width direction, and second compressed areas, each arranged between first and second round areas with its major axis being aligned to a line connecting the first and second round areas.

POROUS SHEET PRODUCT AND METHODS FOR MAKING AND USING THE SAME
20240181122 · 2024-06-06 ·

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.
