The Breaking Strength and Extension of Weathered Rubber-Coated Fabrics.

The breaking strength and extension of a nylon and of a cotton fabric, each coated with natural rubber, neoprene, polyurethane or chlorosulphonated polyethylene and exposed to various weathering conditions, were determined. Although the coated nylon fabrics were stronger and more extensible than the cotton ones, those with natural rubber coating deteriorated at a faster rate when exposed under load. Nylon coated with polyurethane was initially stronger and more extensible than when coated with the other rubbers, but in hot moist weathering conditions deteriorated faster. Extension was more severely affected than strength by load during exposure. Author
