RS TENSILE PVT IN DELHI When the amount of stretching force reaches a certain point, the fabric begins to break. Now we can say that the tensile strength of the fabric is the amount of stretching force (load) at which the fabric begins to break when it comes under stretching conditions. It is measured in Newtons, pounds, or kilogram-force. The tensile strength deals with the force required to break a large number of yarn simultaneously in either warp or weft direction. The force at which the material breaks is directly proportional to cross-section. When the temperature of a material increases then the tensile strength, as well as bond strength, will get increased. But, beyond that, the tensile strength and the elasticity of that material will get decreases. Thus, temperature also plays an important role in changing the molecular structure of a material.
