Polymeric materials are described which have a bioflavonoid coating, the bioflavonoid content of the coating comprising at least naringin and neohesperidin. The use of such coated polymeric materials is also described as well as the process for making the coated polymeric materials.

Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having high interlaminar lap shear strength between component fiber plies or fiber layers, which correlates to low composite backface signature. The high lap shear strength, low backface signature composites are useful for the production of hard armor articles, including helmet armor.

Dimensionally-stable fibrous structures including ceramic-coated melt-blown nonwoven fibers made of a flame-retarding polymer and processes for producing such fire-resistant nonwoven fibrous structures. The melt-blown fibers include poly(phenylene sulfide) in an amount sufficient for the nonwoven fibrous structures to pass one or more fire-resistance test, e.g. UL 94 V0, FAR 25.853 (a), FAR 25.856 (a), and CA Title 19, without any halogenated flame-retardant additive, and have a ceramic coating. The melt-blown fibers are subjected to a controlled in-flight heat treatment at a temperature below a melting temperature of the poly(phenylene sulfide) immediately upon exiting from at least one orifice of a melt-blowing die, in order to impart dimensional stability to the fibers. The nonwoven fibrous structures including the in-flight heat-treated melt-blown fibers exhibit a Shrinkage less than a Shrinkage measured on a nonwoven fibrous structure including only fibers not subjected to the controlled in-flight heat treatment operation, generally less than 15%.

Provided are an engineering plastic composite and a method for producing the same. The engineering plastic composite includes a carbon fiber having a surface modified by a hydrogen plasma and including a functional group and an engineering plastic. The carbon fiber is mixed with the engineering plastic to constitute a composite.

The present invention relates to the field of denim fabric processing, specifically to an environmentally-friendly processing method for dyeing denim fabric with zero discharge. The method includes: step 1, a treatment of white warp yarns; step 2, a primary drying operation; step 3, a coating spray-dyeing operation; step 4, a secondary drying operation; step 5, a sizing operation; step 6, a ternary drying operation; and step 7, a doffing operation. In the present application, as warp yarns are dyed using the coating spray-dyeing technology, highly corrosive auxiliaries such as sodium hydrosulfite and sodium sulfide are not needed in the dyeing process, and the dyed warp yarns are not required to be treated in a washing tank, so that zero effluent discharge is achieved.

Disclosed are textile fibers, yarns, and fabrics having improved comfort and water and odor adsorption properties, and methods of manufacturing same. The improved textiles have an increased distribution of adsorbing particles distributed at the surface of the fibers and yarns to enable greater overall surface area for adsorbance.

The present invention provides a conductive fabric comprising base cloth and a conductive metallic circuit structure formed on the surface of the base cloth. The conductive metallic circuit structure comprises at least one metallic seed layer and at least one chemical-plating layer. The metallic seed layer is an evaporation-deposition layer or a sputter-deposition layer and has a circuit pattern. The chemical-plating layer is applied over the surface of the metallic seed layer. The conductive fabric has improved conductivity and heat generation efficiency.

An electret is disclosed including: a carrier, and polytetrafluoroethylene having a melting point of 35 C. or higher and 320 C. or lower deposited on the carrier, wherein the electret imparts an electrostatic charge to at least one of the carrier and the polytetrafluoroethylene, and has two or more melting point peaks in simultaneous thermogravimetry and differential thermal analysis. An electret filter is disclosed which preferably is used for a filter which requires durability to tobacco smoke. An electret filter is also disclosed having a fluorine-containing component deposited on a fiber surface, wherein an initial QF value is 0.5 mmAq.sup.1 or more in collection efficiency of particles having a particle diameter of 0.3 to 0.5 m at a wind speed of 5 cm/s, and a filter deterioration rate by tobacco smoke loading is 8/(g/m.sup.2) or more.
