Bonded fabrics

Ca.rca.ss Construction. Carcasses are made of one or more pHes of a woven fabric bonded together with an elastomeric compound. Woven materials that are used include cotton, rayon, nylon, polyester, aramids, and glass, in the pure form or in blends. The fabrics are constmcted with warp yams that mn lengthwise along the belt, and filling (weft) yams that mn crosswise. There are a variety of fabric weaves available for specific appHcations... 

The laminated (RP) fabric, bonded with phenolic plastic incorporating antifriction ingredients and cured under heat and pressure, gives excellent service when properly applied in various applications. This group of bearings has a low coefficient of friction, antiscoring properties, and adequate strength for use in steel mills and other heavy-duty applications and is well established in the industry. 

A rubber to fabric bonding system comprising resorcinol, a formaldehyde donor and a hydrated silica filler. Incorporated as dry ingredients in the rubber compound and activated by heat.

This effect may he achieved hy using fibreglass fabric bonded separately to each of the contacting faces of the members in the joint area, in directions of 45° or 90° with respect to the wood grain direction. For members with dowels or bolts loaded perpendicular to the grain, reinforcement can ensure full load carrying capacity even for very small end-distances. Local reinforcement for tension perpendicular to the grain of the timber can also be very effective for end-notched beams. 

The polymerase chain reaction (PCR) is the most widely used technique for oligonucleotide synthesis. Microchips/microdevices for PCR are studied extensively, and thus great progress has been made in the development and scope of microchip components of microchip-based PCR analyzers such as on-chip micromachining (fabrication, bonding, and sealing), choice of... 

Backing n. (1) A general term for any system of yarn, which interlaces on the back of a textile material. (2) A knit or woven fabric or plastic foam bonded to a face fabric. (3) A knot or woven fabric bonded to a vinyl or other plastic sheet material. (4) See carpet backing. Kadolph SJJ, Eangford AE (2000) Textiles. Pearson Education, New York. Complete textile glossary. Celanese Acetate EEC, New York, 2000. 

Green tack n. A term used in fabric bonding for the prehminary bond created in the first stage of curing by the wet adhesive process. At this point, the bond is not fully cured and hence is green . 

Clearly the ability of the geosynthetic to interface with the soil and be anchored by it is a key element in the transfer of the tensile force and hence performance of the reinforced soil structure. Thus soil-geosynthetic interaction, or interface friction, becomes critical as it governs the soil-fabric bonding strength. The required embedded length or bond length is determined by this parameter. 

Fontaine et al (19) introduced 2-vinyl-4,4-dimethylazlactone (VDM) onto polypropylene (PP) fabrics by an electron-beam activated polymerization. The electrophilic azlactone groups were reactive toward nucleophiles without by-product elimination. It was demonstrated that this VDM-modified PP fabric bond sericin by reacting with the nitrogen nucleophilic amino acid side groups of sericin such as lysine, arginine, and histidine, with up to 10% mass uptake. 

All these factors should be considered during the whole process of manufacturing rubber-fabric bonded seals to ensure a quality product. 

There are high performance laminated (RP) fabric, bonded with phenolic plastic incorporating antifriction ingredients. They have given excellent service when properly applied in various applications particularly... 

Rubbep-to-Fabric Bonding. Rubber-to-fabric bonding is of considerable commercial significance in the tire industry and industrial rubber goods such as conveyor belts and rubberized ftibrics. In the tire industry, the so-called resorcinol-formaldehyde (RF) latices are still used predominantly for bonding rayon, whereas mainly resorcinol-formaldehyde-vinylpyridine latices are used for bonding nylon and adhesively finished polyester yams, which, unless specially pretreated, adhere very poorly to rubber. 

Fabric bonding is a relatively new application for adhesives [99]-[103]. The particular demands that a fabric bond must satisfy make the replacement of conventional thread stitching very difficult ...
