Nylon sewing thread process: 100% nylon monofilament piecing, low temperature dyeing to ensure sufficient elongation and resilience of the sewing thread. Characteristics of Nylon Sewing Thread: Elongation at break up to 25-30%, when the thread is stretched to 4-6%, it can rebound 100% to its original length.
Process of polyester high-strength threads: Sewing threads made from 100% polyester filament strands twisted, shaped, dyed and oiled and wound. Characteristics of polyester high-strength threads: polyester high-strength threads are characterised by low elongation and inelasticity. The thread is smooth and free from feathers, with high tensile strength and good colour fastness.
