Tensile textile structure applications

Continuous coating is a well-established process in the non-woven industry. Non-woven textiles reach their final product quality tensile strength, resistance against humidity or surface structure only after the application of appropriate additives to the surface or interior of the textile. In principle, a number of methods are convenient, as shown in Figure 4.107 [167]. 

A tire is a textile-steel-rubber composite the steel and textile cords reinforce the rubber and are the primary load-carrying structures within the tire. Because of the performance demands of fatigue resistance, tensile strength, durability, and resilience, seven principal materials have been found suitable for tire application cotton, rayon, nylon, polyester, steel, fiberglass, and aramid the latter three materials find primary usage in the tire crown or belt region. 

Flexible polyurethane foams are open-cell structures which are usually produced with densities in the range 1.5—3 Ib/ft The major interest in flexible foams is for upholstery applications and thus the load-compression characteristics are of importance. Typical load-deflection curves for polyether and polyester foams are shown in Figure 14.2. The most obvious difference between polyether and polyester foams is the lower resilience of the polyester materials. This feature has led to a preference for polyether foams in cushioning applications. Compared to polyether foams, polyester foams have higher tensile strength, elongation at break and hardness consequently polyester foams are preferred in such applications as textile laminates and coat shoulder pads.
