Weblo = initial length (m, in) ε = strain - unit-less. E = Young's modulus (Modulus of Elasticity) (Pa , (N/m2), psi (lbf/in2)) Young's modulus can be used to predict the elongation or compression of an object when exposed to a force. Note that strain is a dimensionless unit since it is the ratio of two lengths. WebFor the same polymer, the dry-jet wet spinning process generally gives significantly higher fiber tenacity and modulus and lower elongation than the conventional wet-jet wet spinning process. The difference in fiber tensile properties between dry-jet and wet spinning processes is illustrated in Table 6.3 for several polymers. 18 This comparison is …
