Abstract: A coating for protecting a carbon fiber or carbon—carbon (C—C) composite component from oxidation comprises a precursor of fluidized glass applied to the component. The precursor-coated component is gradually heated to a temperature of between 250-650° C. to anneal the coating to the component. Alternatively, a thermally matched refractory coating is applied to the C—C component by chemical vapor deposition to create an initial oxidation barrier. The fluidized glass is then applied on top of the refractory coating to enhance the oxidation barrier.

It enhances yarn processability as evidenced by low fuming, improved mechanical quality at lower amounts of spin finish per yarn, improved mechanical quality at higher draw ratios, and minimal depositing. It improves yarn performance as evidenced by improved strength and wicking.

Abstract: Elastic fibers are described that comprise (i) a polyolefin polymer, e.g., a homogeneously branched, preferably substantially linear, ethylene polymer, and (ii) a photoinitiator, e.g., an aromatic ketone, in an amount sufficient to effect at least a partial cross-linking of the polymer when the fiber is exposed to sufficient UV-radiation to activate the photoinitiator. Articles, e.g., fabrics, comprising fibers of this invention, either alone or in combination with one or more other fibers, e.g., cellulose, nylon, etc., exhibit good heat resistance and elasticity at elevated temperatures.

Abstract: Disclosed is a spandex fiber prepared to be excellent in resistance to both chlorine and heat without affecting the properties of the polyurethane polymer, and manufacturing method thereof. The spandex fiber contains hydrotalcite coated with 0.1 to 10 wt. % of a melamine-based compound. The melamine-based compound includes melamine compounds, phosphor-associated melamine compounds, melamine cyanurate compounds, melamine compounds substituted with an organic compound having a carboxyl group, phosphor-associated melamine compounds substituted with an organic compound having a carboxyl group, or melamine cyanurate compounds substituted with an organic compound having a carboxyl group, which are used alone or in combination. The spandex fiber has a high resistance to both chlorine and heat and is therefore useful for underwear, socks, and particularly, sports apparels such as swimsuit.

Abstract: The strand comprises a group of twisted metal wires, a plastic sheath and a pliant filling compound which fills internal interstices between the twisted wires of the group and a peripheral interstice lying between the periphery of the group and the inner face of the sheath. This peripheral interstice has, in a cross section of the strand, an area of between P×emin and 0.6×S2, where P is the external perimeter of the group of wires, emin=0.05 mm and S2 is the cumulative area of the gaps lying between the periphery of the group and the smallest circle within which the group is inscribed.

Abstract: Extruded net with at least some strands which melt away upon the application of heat while other strands maintain elastic, or other desirable, properties. This netting is advantageously combined with a fabric in which the low melting strands function as an adhesive, while the high melting strands maintain their designed properties in the final laminate product.

Abstract: The use of low specific gravity wood from thinning operations, for example, will produce a lower brownstock viscosity for a given kappa number target. A differential of 200-cP falling ball pulp viscosity has been detected from Kraft cooks of low and high specific gravity wood. Using low specific gravity wood can reduce the bleach stage temperature and the chemical dose needed in the bleach plant to produce lyocell pulp specifications. Low specific gravity wood also increases the ability to reduce pulp viscosity to very low levels without increasing the copper number of the pulp or the concentration of carbonyl in the pulp above acceptable levels.
