  • Process For Pretreatment of Cellulose-Based Textile Materials
    Publication number: 20090311931
    Abstract: The invention is related to mild pretreatment or preparation process as well as combined scoring and bleaching composition for cellulose-based textile material. The process comprises a sequential or simultaneous scouring step with an enzyme composition acting on the non-cellulosic material on outer layers of cellulosic fibers and a reducing bleaching step with a reducing bleaching agent. The reducing bleaching agent is preferably dithionite. In the process no adjustment of pH and temperature are required. The process is environmentally friendly because no causticizing and oxidizing agents are required to achieve the desired lightness and wettability. Due to the mild pretreatment conditions tensile strength of the fabric is better than that achieved with conventional pretreatments.

  • BIODEGRADABLE POLYLACTIC ACID FOR USE IN NONWOVEN WEBS
    Publication number: 20090311937
    Abstract: A method for forming a biodegradable polylactic acid suitable for use in fibers is provided. In one embodiment, for example, a polylactic acid is melt blended with an alcohol to initiate an alcoholysis reaction that results in a polylactic acid having one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the alcoholysis conditions (e.g., alcohol and polymer concentrations, catalysts, temperature, etc.), a modified polylactic acid may be achieved that has a molecular weight lower than the starting polylactic acid. Such lower molecular weight polymers also have the combination of a higher melt flow index and lower apparent viscosity, which is useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.

  • Fibers Formed from a Blend of a Modified Aliphatic-Aromatic Copolyester and Thermoplastic Starch
    Publication number: 20090305592
    Abstract: A fiber formed from a thermoplastic composition that contains a thermoplastic starch and an aliphatic-aromatic copolyester is provided. The copolyester enhances the strength of the starch-containing fibers and also facilitates the ability of the starch to be melt processed. Due to its relatively low melting point, the aliphatic-aromatic copolyester may also be extruded with the thermoplastic starch at a temperature that is low enough to avoid substantial removal of the moisture found in the starch. Furthermore, the aliphatic-aromatic copolyester is also modified with an alcohol so that it contains one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the conditions of the alcoholysis reaction (e.g., alcohol and copolymer concentrations, temperature, etc.), the resulting modified aliphatic-aromatic copolyester may have a molecular weight that is relatively low.

The gelatin non-woven can be cross-linked by heat-treatment or chemical cross-linking, and the non-woven is biocompatible as measured by fibroblast growth in vitro and wound healing on pigs in vivo.

  • LAYERED THERMALLY-INSULATING FABRIC WITH THIN HEAT REFLECTIVE AND HEAT DISTRIBUTING CORE
    Publication number: 20090209155
    Abstract: A composite fire-resistant, heat-diffusing, and heat-reflective article. The article includes at least two layers of a fire-retardant and heat-resistant fabric with a heat diffusing and/or heat-reflective core disposed between the fabric layers. The core may include at least one layer of a thin metal foil (e.g., thin aluminum foil). The composite fire-resistant, heat-diffusing, and heat-reflective article provides durability, fire resistance, and the ability to withstand high heat exposure on one face for an extended period of time without transferring significant heat to the opposite face. Combining fire-retardant fabrics with a heat diffusing and/or heat-reflective core achieves a true synergy by offering greater fire and heat protection to persons and structures than either component can offer alone.

  • Stretched polymers, products containing stretched polymers, and their methods of manufacture and examination
    Publication number: 20090202801
    Abstract: Certain stretched polymers have defects which reduce their tenacity and effectively render the stretched polymers opaque. These defects are at least in part cause by the undesirable stresses being applied to the fiber. Such stresses may be avoided by avoiding thermal shock and by avoiding bending and twisting during processing. Such stretched polymers may be used in optically clear application such as bullet resistant glass.

  • BIODEGRADABLE ALIPHATIC-POLYESTER FOR USE IN NONWOVEN WEBS
    Publication number: 20090203281
    Abstract: A method for forming a biodegradable aliphatic polyester suitable for use in fibers is provided. In one embodiment, for example, an aliphatic polyester is melt blended with an alcohol to initiate an alcoholysis reaction that results in a polyester having one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the alcoholysis conditions (e.g., alcohol and polymer concentrations, catalysts, temperature, etc.), a modified aliphatic polyester may be achieved that has a molecular weight lower than the starting aliphatic polyester Such lower molecular weight polymers also have the combination of a higher melt flow index and lower apparent viscosity, which is useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.

  • MEMBRANE ENCAPSULATED FIBER AND METHOD FOR PRODUCING SAME
    Publication number: 20090176422
    Abstract: This invention generally relates to the production of a composite yarn or non-woven strand wherein a core of super absorbent polymer fibers (SAP's) having a swell factor of approximately 250% and greater are encapsulated by a nonwoven membrane of defined porosity. The membrane is then sealed in a fashion to generally deter or prevent the SAP material from migrating out of the core as water is freely absorbed and desorbed from the composite yarn structure. The strands of yarns or strips of non-woven material are subsequently constructed into an open or unorientated fabric formation. When used as a subterranean fabric, structure or material, the resultant fabric structure retains moisture while permitting normal root growth and allowing excess water to pass through and beneath the fabric while facilitating movement of water from lower levels to the surface.
