Effect of Workwear Fabric Characteristics on the Changes in Tensile Properties of Sewing Threads after Sewing [PDF]
During sewing at high speed, the needle thread issubjected to repeated tensile stresses, heat, bending,pressure, torsion and wearing. These stresses act onthe thread repeatedly and the thread passes 50-80times through the fabric, the needle eye and ...
