Preparation of polyester mixed twist yarn and polyester mixed twist yarn

摘要

The present invention is poly relates to a polyester composite false-twist yarn production method and a polyester composite false-twist yarn, polyester salt reflections cationic dye addition salt polyester yarn of 60 high entangling strength and stirring raksu than 90% by using the air entangling apparatus after the inter-woven with at least / m, the poly that the resulting T Laksa under 100 ℃ condition of the composite false-twist draw ratio in the composite false-twist temperature composite false twist temperature, and 1.05 a composite false-twist draw ratio 1.15 range in the range 160 ℃ characterized in that the composite false twist provided the ester composite false-twist yarn production method and having a polyester composite false-twist yarn structure crimp characteristic expression is seam chosa manufactured in this manufacturing method, it is possible to have the height of the part castle on a straight knitting and expressing excellent melange effect.
