  • Method of producing deeply creped fabric with partially bulked yarn
    Patent number: 3938227
    Abstract: A method of producing a novel deeply creped fabric by using partially bulked yarn. Gyratory (or torque-imparted) partially bulked yarn obtained from a known twisting - heat setting - untwisting process is additionally twisted, or said process is conducted on the pre-twisted yarn to give extra twists to the non-bulked portions, so as to make conspicuous the difference between the bulked and non-bulked portions, and a fabric is woven or knit by using such yarn and is subjected to a creping treatment.
