摘要:
The invention provides novel polyesters, fibers and films, nonwovens from the fibers and disposable products of the polyesters such as diapers. The products are degradable under the conditions typically existing in waste compositing processes, have low ingredient costs and yet provide strength and toughness properties adequate for end uses such as in disposable diapers. The polyesters are based upon polyester ingredients, such as polyethylene terephthalate, copolymerized with an alkali metal or alkaline earth metal 4-sulfophthalic acid derivative, and other ingredients, such as polyethylene ether glycols and/or non-aromatic diacids, such as adipic and glutaric acids.
摘要:
A new gel-like composition of matter containing a complex carbohydrate with a high degree of carboxyl substitution cross-linked by an organic cross-linker has been developed. The cross-linkers have complex ring structures, e.g., polynuclear or heterocyclic compounds, which permit development of two distinct partial positive charges under conditions where a carbohydrate is negatively charged. Antibiotics are the preferred cross-linking agents and a method of sustained release of the antibodies is also disclosed.

The invention provides novel polyesters, fibers and films, nonwovens from the fibers and disposable products of the polyesters such as diapers from the nonwovens. The products are degradable under the conditions typically existing in waste composting processes, have low ingredient costs and yet provide strength and toughness properties adequate for end uses such as in disposable diapers. The polyesters are based upon polyethylene terephthalate copolymerized with diethylene glycol and a 5-sulfoisophthalic acid.
摘要:
A multi-layered composition including an outer cover of natural fabric and cotton felt, and an absorbent core having a top layer of a natural feather fabric and a lower layer of a waterproof coating of wax. The absorbent core may further include as a second layer natural fluffed pulp and gel. The composition is adapted for use in a product such as a nappy or diaper, a personal product, clothing item or protective item incorporating the composition.
摘要:
A disposable diaper comprising a liquid permeable bodyside inner liner and an at least substantially liquid impermeable outer layer, which form a front panel and a rear panel, with a liquid-absorbent batt sandwiched between the inner liner and the outer layer, and with elastic leg openings, characterized in that the inner liner and the outer liner are at least substantially made of a cellulosic material of the "wet-strong long fiber" type.
摘要:
A biodegradable diaper. The diaper has an outer sheet of biodegradable material able to resist water absorption. An inner sheet of biodegradable material is able to allow the passage of water and is attached to the outer sheet by a biodegradable adhesive at the periphery to form an envelope. A super absorbent core is located within the envelope. There is a water resistant film of biodegradable material located within the core to assist in fluid distribution into the core.
摘要:
Disposable sanitary garments comprise topsheet and/or backsheet materials prepared from polymers based on dioxanone. Diapers, sanitary napkins, pantiliners, and the like, prepared from the foregoing materials are disclosed.
摘要:
A sanitary absorbing construction to be used by children and infants to hold and restrain liquid and solid dejections, which article is conventionally called napkin, of a single-use or disposable kind, made by combining different raw synthetic or natural materials, comprising apple waste materials, being industrially transformed into composite sub-layers which are assembled together to form articles having different shapes depending on technical or aesthetical requirements, and being biodegradable either before or after their use, when released into the environment, and being compostable or able to be transformed to into organic amending materials, when properly collected and separated or mixed with other organic domestic waste materials and then let into the compost cycle, per se or together with organic waste materials either from foodstuff or not.
摘要:
An absorber and an absorbent article which have excellent leak proof property during use and water disintegratability after disposal. The water disintegratable absorber includes a water disintegratable absorber layer and a water insoluble resin layer. The amount of water absorption of the water disintegratable absorber layer is 300 g/m2 or more and tear strength in the plan view direction of the water insoluble resin layer is 0.15 N/40 mm or less in a first direction as well as a second direction that is orthogonal to the first direction.

摘要:
A method of producing an absorbent composition. A polymeric material characterized as having surface anionic reactive sites is mixed with a source of multi-valent metal ions to render the polymeric material sorbent of aqueous liquids. A dispersant is then added to form a wet slurry which is subsequently dried to a granular consistency.
