摘要： The present invention relates to a biodegradable substrate having a durable hydrophilic surface prepared from a biodegradable polymeric substrate having a surface, wherein the biodegradable polymeric substrate has been rendered hydrophilic by subjecting the substrate to a corona glow discharge and/or coating the substrate with a hydrophilic polymeric material in an amount of from about 0.01 to about 2.0 percent by weight, based on the dry weight of the substrate. The biodegradable substrate can be used in absorbent personal care product, biomedical devices and food packaging.

摘要： The present invention provides a nonwoven web prepared from an aliphatic polyester polymer which has sufficient tear strength and is biodegradable. Biodegradable nonwoven webs of the present are prepared from a polymer blend having from about 65% by weight to about 99% by weight of a biodegradable aliphatic polyester polymer and from about 1% by weight to about 35% by weight of a second polymer selected from the group consisting of a polymer having a lower melting point than the biodegradable aliphatic polyester polymer, a polymer having a lower molecular weight than the biodegradable aliphatic polyester polymer and mixtures thereof. Surprisingly, the nonwoven webs of the present invention have a tear strength greater than the tear strength of a nonwoven web prepared from the biodegradable aliphatic polyester polymer alone. In addition, other properties of the resulting nonwoven web, such as the tensile strength and energy to break, are not adversely affected, by the addition of the second polymer, in ways that make the resulting nonwoven web unusable for its intended purpose.

摘要： A method of preparing a nonwoven web that has substantially continuous synthetic fine fiber includes preparing an aqueous amide crosslinked polymer solution. The solution is extruded through a die having a plurality of orifices to form a plurality of threadlines. The threadlines are then attenuated with a primary gaseous source under conditions sufficient to permit the viscosity of each threadline to increase incrementally with increasing distance from the die, at a rate sufficient to provide fibers having a desired attenuation and mean fiber diameter without significant fiber breakage.

摘要： An absorbent article includes a vapor permeable backsheet, a liquid permeable topsheet positioned in facing relation with the backsheet; and an absorbent body located between the backsheet and the topsheet. The absorbent body may include multiple zones of high air permeability or may include materials which provide improved air exchange after being wetted. The absorbent article may also include a ventilation layer between the absorbent body and the backsheet and a surge management layer between the absorbent body and the topsheet. The article exhibits improved air exchange within the article during use. As a result, the article exhibits substantially reduced levels of hydration of the wearer's skin when in use which renders the skin less susceptible to the viability of microorganisms.

摘要： Disclosed is an absorbent composition comprising each of an acidic and a basic material, wherein the absorbent composition exhibits desirable absorbent properties. Specifically, the present invention relates to an absorbent composition comprising either an acidic water-swellable, water-insoluble polymer having a pKa between about 2 to about 12 or a basic water-swellable, water-insoluble polymer having a pKb between about 2 to about 12 and either a basic or an acidic second material. The absorbent composition has the ability to slowly absorb a large quantity of liquid, particularly while under an external pressure. The absorbent composition is useful in disposable absorbent products, such as those disposable absorbent products that are used to absorb bodily liquids.

摘要： Certain antimicrobial agents, particularly chitosan- or chitin-based polymers, exhibit increased antimicrobial activity when coated onto the surface of a hydrophobic material such as polypropylene. When applied to the surface of a polypropylene nonwoven fabric, for example, the resulting material can be used for diaper liners to reduce odors and promote skin wellness.

摘要： Absorbent articles with carefully controlled stretch properties are disclosed. In particular, the absorbent articles have a waistband that encompasses a pair of opposing side panels and a waist region of the article. The side panels are attached to longitudinal edges of a chassis and are configured to extend around a person's waist. The side panels are attached to fastening devices for fastening the absorbent article to a wearer. In accordance with the present invention, the side panels and the waist region are both elastic. In order to improve fit and comfort, the stretch properties of the side panels are matched with the stretch properties of the waist region. For example, elongation of the side panels can be matched to elongation of the waist region or, alternatively, displacement of the side panels can be matched to the displacement of the waist region for a given range of forces.
