摘要:
This invention relates to improved adhesion compositions and textile materials and articles treated therewith. The improved adhesion composition comprises a non-crosslinked resorcinol-formaldehyde and/or resorcinol-furfural condensate (or a phenol-formaldehyde condensate that is soluble in water), a rubber latex, and an aldehyde component such as 2-furfuraldehyde. The composition may be applied to textile substrates and used for improving the adhesion between the treated textile substrates and rubber materials. End-use articles that contain the treated textile-rubber composite include, without limitation, automobile tires, belts, and hoses as well as printing blankets.
摘要:
Provided herein are several inventive fabrics having warp yarns and fill yarns, where the warp yarns preferably are an intimate blend of synthetic and cellulosic fibers and where the fill yarns are preferably a patternwise arrangement of synthetic and cellulosic yarns. Such fabric possesses sufficient cellulosic content (i.e., at least 45% by weight) to be easily rendered flame retardant, while simultaneously possessing sufficient synthetic content (i.e., at least 30% by weight) to be abrasion resistant and long-lasting. In one embodiment, the subject fabrics are treated with one or more flame retardant chemicals, typically in the presence of ammonia gas. In a second embodiment, the subject fabrics are coated on one side with an elastomeric composition into which a flame retardant compound has been incorporated. In yet another embodiment, the subject fabrics are both treated and coated to achieve flame retardance.

A screen or fencing structure which provides one-way viewing characteristics under conditions of substantially equal lighting on each side of the structure is described. The structure has a fabric which has a light transmission of about 2.8% to about 25%. The first side of the structure has an overall light reflectance to light transmission ratio of greater or equal to about 2.5, and the opposite side of the structure has an overall light reflectance to light transmission ratio of less than or equal to about 2. Fabrics that can be used to make screens are also described.
摘要:
A filter for reducing heavy metals in a flue gas contains a textile having on at least one side a plurality of treated activated carbon particles. The treated activated carbon particles contain a plurality of activated carbon particles, a hydrophobic agent, a mercury oxidation facilitation agent, and optionally a binder.
摘要:
A flame retardant composition comprises a phosphorous-containing polymer. The phosphorous-containing polymer can be produced by first reacting a phosphonium compound and a nitrogen-containing compound to produce a precondensate compound and then reacting the precondensate compound with a cross-linking composition. The resulting phosphorous-containing intermediate polymer can then be oxidized to convert at least a portion of the phosphorous atoms in the polymer to a pentavalent state. A textile material comprises a textile substrate and a phosphorous-containing polymer, such as that described above.
摘要:
A treated textile material comprises a plurality of yarns or fibers having a hindered amine or halamine compound disposed on the exterior surface of the yarns or fibers and/or dispersed in the interior portion of the yarns or fibers. A treated textile material comprises a finish on a surface thereof, the finish comprising the product of a reaction between a cross-linking agent and a polymer comprising a plurality of secondary, hindered amine moieties attached to the polymer chain. Methods for making the treated textile materials are also described.
摘要:
The present disclosure relates to a protective garment system having two primary components. The first component, which serves as the outer layer of the garment, comprises a textile substrate that has been treated on one side with a hydrophobic composition and has been treated on the opposite side with an oleophobic composition. This combination is well-suited for protection against a variety of organic, oily type liquids (such as chemical warfare agents). The second component, which is a composite structure that serves as the inner layer of the garment, contains a core of activated carbon positioned between layers of adhesive and textile substrate.
摘要:
A composite is disclosed for use as military protection suit material against biological and chemical warfare agents. The composite comprises at least five layers and has two outermost sides. The outermost layers of the composite are textile substrates, such as woven, knit, and nonwoven fabrics. The middle layer is comprised of activated carbon granules positioned between, and secured to, the two textile substrates by adhesive. The adhesive layers provide durable bonding between the textile substrates and the activated carbon layer. The resulting composite is both breathable and flexible.
