SEPARATING TYPE CONJUGATED YARN

摘要

The split type composite yarn is composed of fiber-forming polyester as a first component which forms small round-shaped portion (A1) at the center of cross-section of composite yarn, with branched portion (A2) extending toward outer part of composite yarn cross-section radially, and fiber-forming polyamide as a second component which forms segment (B) aligned in ⊙ form between each branched portion (A2), in a way that the whole area of B occupies 60-80 % among whole cross-section of composite yarn, contact portion between (A2) and (B) forms curve, and ratio between diameter (r) of A1, and diameter (R) of composite yarns cross-section, between width (a) of outer-most of (A2) and maximum width (b) of (A2) satisfy the equation of 1/10 < r/R < 1/5 and 4/3 < b/a <= 2.
