Abstract:
A blackout drapery lining (10') including a first substrate (12) of a textile material having an inner surface and an external surface, the external surface forming a first finished surface of the drapery lining. A first adhesive layer (14) having an opaque pigment is adhered to the first substrate and covers the inner surface of the first substrate to provide a substantially light impermeable barrier for the drapery lining. The drapery lining also includes a second substrate (16) of a textile material having an inner surface and an external surface, the inner surface of the second substrate being adhered to the first adhesive layer and the external surface of the second substrate forms a second finished surface of the drapery lining.
Abstract:
A composite element (12) comprises a non-woven web (14) of fibrous material, e.g. filament glass fibers (16), with a substantial number of interstitial spaces or voids (18) which contain a phenolic resin material (20) having a chemical flame retardant (22) therein. Additionally, the composite element (12) comprises a scrim layer (24) of woven cloth or coarsely woven, grid-like scrim which may also contain filament glass fibers (26) as a strengthening element. The scrim layer (24) is impregnated with a phenolic resin (28). A thin layer of polymeric film (30) acts as an air impermeable barrier. A layer of metallic film (32) can be included to render the composite element (12) impermeable and to reflect heat. The composite element (12) in the presence of fire has levels of heat release, flammability, smoke release and toxic gas release below predetermined levels considered suitable for use within the passenger compartment of a commercial aircraft.
Abstract:
A liquid-impermeable tissue (10) for use in medical applications and the like where it is desirable to insulate the user's fingers and/or hand from hazardous contaminants, such as infected body fluids and carcinogenic chemicals. The liquid-impermeable tissue (10) comprises a soft, absorbent first layer (20) and a strong, liquid-impermeable second layer (22). The absorbent layer (20) can be used for cleaning in much the same manner as contemporary tissues. The strong, impermeable second layer (22) prevents the user from becoming contaminated by either the absorption of liquids through the absorbent first layer (20) or be tearing through the absorbent first layer (20) and directly contacting the contaminants. Thus, the liquid-impermeable tissue (10) of the present invention insulates the user from potential contamination in a wide variety of cleaning situations.
Abstract:
A printable display media laminate (10) for use as a point of purchase sign or the like comprises a face stock layer (12) which may be paper or other easily printable material. A coating composition (14) is extrusion coated onto a face of the paper or other face stock material to provide a "clinging" layer to form a self adhering laminate which is positionable on a smooth surface and is easily removed without leaving any adhesive residue or the like. The coating composition may be an ethylene-vinyl acetate copolymer having a predetermined content of vinyl acetate, and may include stabilizers and aged adhesion inhibitors. The laminate is positioned on a substrate by pressure induced adherence and is selectively repositionable. The face stock material is amenable to a variety of printing techniques including offset printing to provide extremely useful and cost effective product.
Abstract:
A flame retarding and fire blocking structure comprising a polymeric material selected from polymeric binders or natural or synthetic polymeric fibers, blended with nonflammable, substantially permanently or irreversibly heat set carbonaceous fibers having a carbon content of greater than 65 percent and an LOI value of greater than 40, wherein said carbonaceous fibers are present in the blend in an amount of at least 7.5 percent.
Abstract:
A laminate which comprises an inner layer containing an acid-base indicator and indicator-free outer layers. The inner layer can undergo changes in its color when in contact with an acid or alkali.
Abstract:
It is an object of the present invention to provide novel signs and visual displays produced by different behavior of liquids applied to hydrophilic and hydrophobic surfaces on patterned surfaces. It is also an object of the present invention to provide articles baring logos and alphanumeric text produced by application of liquids to patterned material surfaces. There is further provided a method for producing novel signs and visual displays by producing patterned hydrophobic and hydrophilic surfaces. Also provided are processes for producing patterned surfaces.
Abstract:
A system for removing extraneous, random free-flowing dyes from laundry washing applications which comprises a novel unitary dosing laundry article that can freely circulate among items being laundered. The laundry article further comprises a dye absorber and a dye transfer inhibitor which are introduced into a wash liquor via a support matrix. The dye absorber maintains a relational association with the support matrix in the wash liquor, whereas the dye transfer inhibitor is delivered up from the support matrix to the wash liquor and may be evenly distributed throughout the wash liquor. The laundry article of the present invention provides a method for preventing the redeposition of extraneous dyes onto other wash items, while simultaneously providing an indicator system for the manifestation of such scavenging process.
Abstract:
The present invention provides a method of preparing a sized warp yarn comprising the steps of (a) preparing a warp yarn sizing composition comprising (i) a first component which is a starch material, and (ii) a second component comprising starch and a reaction product of styrene and 1,3-butadiene wherein said starch component of said second component is characterized by an intrinsic viscosity of from about 0.07 to about 0.35 dl/g and (b) slashing warp yarn with the sizing composition of step (a).
