Effect of Workwear Fabric Characteristics on the Changes in Tensile Properties of Sewing Threads after Sewing
Tenacity Breaking elongation
2010/9/20
During sewing at high speed, the needle thread is subjected to repeated tensile stresses, heat, bending, pressure, torsion and wearing. These stresses act on the thread repeatedly and the thread passe...
