摘要:
A textile article such as a floor covering or carpet is disclosed. In one embodiment, a floor covering is provided with a composition applied to the surface of the floor covering. The composition resists staining and dry soiling, and provides liquid repellency and stain release properties. The composition may employ a repellent component, a stain resist component, a stain release, and a particulate component. The composition may be applied to fibrous-containing textiles, such as carpeting. A method of applying the composition to a textile is disclosed. The repellent component may employ a fluorochemical, such as a fluorocarbon. The repellent may be acrylic-based or urethane-based, as two representative examples. The composition is adapted for imparting to a textile a chemical finish that will resist moisture, release stains, and resist dry soiling.

A porous substrate for organic solvent-based ink printing may be coated with a repellant composition to form a coated substrate surface that is suitable for high quality solvent-based ink jet printing. The coated substrate surface may exhibit a repellancy for butoxyethyl acetate solvent at a contact angle of between about 40 and about 90 degrees at ambient temperature. In some applications, the repellant composition includes a fluorocarbon polymer, or a urethane. Solvent-based ink applied to the porous substrate will form droplets which under the application of heat deposit ink in a controlled and advantageous manner upon the treated substrate surface. An optional acrylate-based latex material may be employed in the repellant composition. A printed substrate is produced which exhibits clear, sharp and high quality print.

This invention relates to antimicrobial fabrics which are treated with a specific durable and regenerable halamine/chlorine system and methods of removing residual active chlorine from the target textile surface without reducing the antimicrobial activity of the textile. Such methods comprise contacting an amine-treated fabric first with a halogen-based bleach (or other halogenated liquid) to produce halamines at the fabric surface, and subsequently washing the resultant halogenated fabric with a reducing agent which removes the residual, unbonded halogen (such as chlorine) from the fabric surface but does not, surprisingly, remove the halamine halogen. The remaining halamine halogen thus provides the desired antimicrobial activity. As a result, a method of substantially reducing fabric discoloration, odor, and potential skin irritation due to the presence of amounts of residual unbonded halogen (such as chlorine) on the target fabric surface is provided which simultaneously permits sufficient amounts of halamine halogen (such as chloramine chlorine) to remain on the target fabric for optimum microbiocidal propoerties. A fabric treated in accordance with this method is also provided.

Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeability. The inventive inflatable fabrics are primarily for use in automotive restraint cushions that require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessarily low permeability levels. Thus, the inventive coated inflatable airbag comprises a film laminated on at least a portion of the target fabric surface wherein the film possesses a tensile strength of at least 2,000 and an elongation at break of at least 180%. The film provides a low permeability airbag cushion exhibiting a leak-down time of at least 5 seconds as well as a very low packing volume (for more efficient use of storage space within a vehicle) for the target side curtain airbag.

A cable assembly includes a cable member and an outer jacket member disposed about the fiber optic cable member in slidable relation. In a preferred embodiment, the outer jacket member is a woven article, made from low friction, synthetic fibers such as polyester, nylon, Teflon, PEEK, or polyvinylidene fluoride. The outer jacket member serves as a sleeve that extends at least the same length as the cable member. In use, the outer jacket carrying the cable member may be attached at one end to a pull cord or tape that extends through the length of a conduit. A pulling force is exerted on the pull cord at a remote end of the conduit, causing the outer jacket member and cable member to be drawn through the conduit. The outer jacket bears most of the force of the pulling action, and the only force exerted directly on the fragile cable member is that of friction between the jacket and the cable. This arrangement substantially increases the amount of force and speed with which the cable assembly may be drawn through the conduit, while reducing the amount of friction and eliminating the need for lubricants during the process.

A process for imparting long-lasting antimicrobial properties to fabrics is disclosed which entails the diffusion of triclosan esters within each individual fiber of a textile. One preferred method is performed in a standard jet dye bath which requires a high range of temperatures to effectively color fabrics. Dyeing in this manner also involves diffusing compounds within individual fibers; thus, this manner of incorporating dyestuffs and colorants within textile fabrics provides a compatible and effective vehicle for simultaneously introducing triclosan esters within such textile fibers, also. A dye bath application is not required, however, as any procedure which allows contact between a triclosan ester derivative and a fabric at a sufficient temperature and for a sufficient time to effectuate diffusion of the ester within each individual fiber of the fabric is also contemplated within this invention. The inventive triclosan esters do not easily wash off and do not lose their antimicrobial characteristics upon contact with bleaching agents.

This invention relates to novel airbag coating compositions comprising at least two separate and distinct layers. The first layer (base coat), being in contact with the airbag surface, comprises a non-silicone composition of at least one coating material, provides excellent adhesion, excellent tensile strength, and lower cost than standard silicone materials. The second layer, being a coating for the first layer, provides excellent reinforcement and aging characteristics to prevent degradation of the first layer. Such a second layer (topcoat) is preferably a silicone material. This two-layer system permits excellent strength and aging properties to prevent seam combing at relatively low cost due to the inexpensive basecoat materials and the relatively low amount required for the topcoat. An airbag fabric coated with this inventive two-layer system is also contemplated within this invention.

This invention relates to novel airbag coating compositions comprising a mix of polyurethane and polyacrylate constituents which provides a highly effective low permeability treatment on a target fabric surface. This inventive composition also provides a low-cost alternative to other standard airbag coatings and exhibits excellent aging stability as well. An airbag fabric coated with this inventive composition is also contemplated within this invention.
