Methods of test for elastomeric threads - Polyurethane thread (elastane yarn)What is BS 5421 2 Methods of test for polyurethane thread about? BS 5421 is a series on methods of test for elastomeric threads. Elastomeric threads are polymers with viscoelasticity (i. e., both viscosity and elasticity) and with weak intermolecular forces, generally with low Young's modulus and high failure strain compared with other materials. BS 5421 2 describes eight methods of test for polyurethane thread (elastane yarn): method 1 Preparation of
