LATENT CRIMPING TYPED POLYESTER CONJUGATED YARN WITH TWO COMPONENT

摘要

A latent crimping type of polyester conjugate yarn with two components is provided to offer the good applicability due to a little deviation of flexibility when manufacturing textile fabrics or knitting. Polyetherester resin and polytrimethyleneterephthalate resin are compositely spun as a side by side type or a sheath/core type. A small amount of additive such as matting agent or UV(Ultraviolet) protection agent is added into the two kinds of polymers. The polytrimethyleneterephthalate resin includes the trimethyleneterephthalate repetition unit of above 85 mol %. The polyetherester resin is the copolymer of a hard segment and a soft segment.
