Manufacturing method of high elasticity recycled PET/PTT-based latent crimped composite yarn with excellent deep colorability and fabric using the same

摘要

The present invention relates to a highly stretchable recycled PET/PTT latent crimped composite yarn with excellent deep color properties that can exhibit new functionality by combining recycled polyethylene terephthalate partially drawn yarn and recycled PET/PTT latent crimped yarn. Recycled polyethylene terephthalate partially drawn yarn and recycled PET/PTT latent crimped yarn are subjected to multi-stage heat treatment and air entanglement to express natural sensibility differentiated from existing composite yarns. expression is possible. According to the present invention, the latent crimped composite yarn produced by forming recycled polyethylene terephthalate partially drawn yarn and recycled PET/PTT latent crimped yarn by multi-stage heat treatment and air entangling has excellent blend fineness and improved workability.
