Similar high-quality rubber-to-textile adhesion can be obtained with glass and polyester woven fabrics. Also corded fabric (e.g. tyre cord) reacts in a similar manner to give bond strength breaks within rubber (R-R) when diisocyanates, such as MDI, are used as adhesive treatments. 

At the present time, the principal use of vinylpyridine rubbers is in latex form for the treatment of textile fibres to improve rubber-to-textile adhesion in tyres. 

As stated previously, precipitated silica is being used to replace the carbon black filler in so-called green tyres where it has been shown to reduce rolling resistance [43-46], and so help to reduce fuel consumption. Since the late 1960s, silica has been used in combination with resin systems and at that time PPG introduced a system that consisted of HI-SIL hydrated silica, resorcinol and hexamethylene tetramine (HRH). Initially it was used chiefly for bonding various rubbers to textiles, but such systems have found increasing use in wire coat and belt compounds. 

Terpolymers of butadiene, styrene and vinyl pyridine (75/15/15) have been of some interest in rubber-to-textile bonding, the presence of the vinyl pyridine improving the degree of adhesion as compared with straight SBR latices. 

Some examples in which the mechanical mechanism is important are in the adhesion of polymers (elastomers and rubbers) to textiles. Another example, though somewhat contentious, is the metal plating of a plastic which usually requires a pretreatment to modify the surface topography of the polymer. Usually the increase in adhesion is also attributed to an improved surface force component due to the increased mgosity. 

Of all the MA-based monomers the maleimides and bismaleimides (see Chapter 12) would appear to offer the greatest potential for future commercial exploitation. The maleimide residue helps to improve the heat and chemical resistance, as well as raise the glass transition temperature, of polymeric materials.Bismaleimides are also known to improve the adhesion of rubber to textile fibers, giving improved vulcanizates. The N-phenyl-maleimide copolymers would appear to hold particular promise as new materials. 

RF resin has been used to achieve good rubber-to-textile cord adhesion since 1938. There are very few alternatives, and the substitutes have not really been proven viable in the long term. 

Sulfur dioxide is used in the production of resorcinol, which is used to make RF liquid resin for RFL dips for good rubber-to-textile adhesion. 

Results obtained by Van Ooij in his ESCA studies on the composition of interfaces between rubber and brass" confirm that cobalt salts and HRH form essentially the same inter-facial products with a standard brass surface. Therefore, the mechanism of brass-rubber bonding must be the same for both bonding systems and differences in adhesion values must be explained by a modification of rubber properties (crosslink density, cure rate, modulus, etc.) or the rate of brass attack. Clearly, adhesion of brass to HRH-NR compounds cannot be explained on the basis of hydrogen bonds with the substrate, as in rubber-to-textile bonding. 

Adhesion of rubber to textile material is improved by impregnation with resorcinol compound dissolved in mineral spirit. Textile sheet-like structure is impregnated with an antimicrobial active ingredient solution. The solvent is selected from aliphatic alcohols, aromatic alcohols, glycols and water. ...
