    Abstract: A film that is formed from a biodegradable polymer blend of different aliphatic-aromatic copolyesters is provided. More specifically, the blend contains a first copolyester formed from a terephthalic acid monomer. The use of a terephthalic acid monomer results in a polymer chain containing 1,4-(para-) terephthalate units linked in a generally linear configuration (e.g., ˜180°). The blend also contains a second aliphatic-aromatic copolyester formed from a phthalic acid and/or isophthalic acid monomer. The use of such a monomer results in a polymer chain containing 1,2-(ortho-) and/or 1,3-(meta-) linked units. The inclusion of 1,2-(ortho-) and/or 1,3-(meta-) linked units into the polymer backbone of the second copolyester introduces an angle or “kink” (e.g., ˜120° kink for a 1,3-linkage) into the otherwise linear polymer chain.

  • Publication number: 20090131896
    Abstract: The absorbent article is sequentially provided with a surface sheet (1) facing the skin, allowing excremental liquid to permeate through it and constructed from a perforated sheet, a permeation sheet (2) allowing the excremental liquid to permeate through it, and an absorbent element (3) located on the rear surface side of the permeation sheet (2) and containing cotton-like pulp for holding the excremental liquid. Soft feces permeation speed S1 of the surface sheet (1) is higher than soft feces permeation speed S2 of the permeation sheet (2). Permeation apertures for excremental liquid are formed at least that portion of the apertured surface sheet (1) which faces an excretion section for receiving the excremental liquid and also formed at an excretion region including the portion. In the permeation apertures, an effective opening area of a single permeation aperture (H) is 3-75 mm2 and an opening area ratio is 10-80%.

    Abstract: A releasable mechanical fastener is provided using the hook or mushroom male strap, and instead of a dedicated female strap, utilizes a support and operational surface of the item to be fastened as the female material. A clothing or personal hygiene item is further provided, by way of example an infant diaper or an incontinence pad, utilizing a closable strap. The female material of the invention is not confined and not applied, but rather occupies and constitutes the support and operation surface of the device: it actually forms such surface of such clothing or personal hygiene item.

  • Publication number: 20090104253
    Abstract: A hemostatic biocidal dressing includes pro-coagulant and biocidal agents providing a physical barrier to bleeding as well as chemical action to promote blood coagulation and thereby arrest coverage. At the same time, biocidal properties of the dressing prevent the introduction of infected agents and the establishment of infection within wounded tissue. A silverized textile provides biocidal action while a granulated hemostatic agent disposed within interstitial regions between polymer fibers provides coagulating action.

  • Publication number: 20090099539
    Abstract: Potty training liners are a comfortable, child sized, absorbent liner, with a concave center and an expandable, flexible bottom to allow rapid flowing urine collection and retention. The Liner has unique absorbent collapsible side walls with an unobstructed center containing superabsorbent for quick pooling of urine. The liner is adhered to the inside of the child's underwear with a thick adhesive strip on the bottom outer portion of the liner. The Liner is soft and flexible, and does not have the feel of a diaper. It is a unique stop-gap solution for children progressing from pull-on diapers to unprotected underwear. The purpose of the liner is for training, and short term emergency “accident” protection, as opposed to long term wearable protection.
