WATER SOLUBLE FIBERS WITH POST PROCESS MODIFICATIONS AND ARTICLES CONTAINING SAME
A method of treating a fiber includes admixing a fiber comprising a polymer comprising at least one of a vinyl acetate moiety or a vinyl alcohol moiety and having a degree of hydrolysis less than 100% with a hydrolysis agent solution to form a mixture so as to increase the degree of hydrolysis of at least a portion of the fiber.
ADHESIVE TRANSPARENT MULTIFUNCTIONAL WOUND-COVERING MATERIAL AND MANUFACTURING METHOD THEREOF
The present invention has absorbency for the exudate of the wound surface and can maintain a moist environment suitable for promoting healing of the wound surface for a long time, an adhesive transparent multi-functional wound-covering material and a method for manufacturing the same are proposed so as not to cause pain or damage to the regenerated skin when replacing the wound dressing. Such a wound-covering material includes 14% by weight of polyvinylpyrrolidone, 5% by weight of propylene glycol, 79.0996% by weight of water, 0.6% by weight of calcium chloride, 0.3% by weight of potassium sorbate, 0.0004% by weight of RH oligopeptide, and 1% by weight of D-xylitol.

CD Extensible Nonwoven Composite
A nonwoven composite that has a dimension in a machine direction and a cross-machine direction is provided. The composite comprises a nonwoven facing positioned adjacent to an elastic film. The nonwoven facing contains a spunbond web that is formed by necking a base spunbond web. The base spunbond web includes a plurality of fibers generally oriented in the machine direction and exhibiting a machine direction tensile strength and cross-machine direction tensile strength. The ratio of the machine direction tensile strength to the cross-machine direction tensile strength is about 4:1 or more.

Delivery systems
Disclosed herein are delivery systems including coated and uncoated yarns, yarn precursors, threads, fibers, and other substrates for the constant or near-constant release of active compounds, as well as methods for manufacturing such delivery systems. The yarns, yarn precursors, threads, fibers, and other substrates can include a cross-linked hydrophobic elastomer and an active compound. One or more coatings that are impermeable or substantially impermeable to the active compound may partially or fully occlude the yarn or substrate to control release rates of the active compound. The delivery systems may be used in a variety of applications, including the making of articles of clothing, textiles, and fabrics, and may be used in methods of treating various conditions and diseases.
