HIGH AIR PERMEABILITY FABRIC WITH SMALL CHANGE RATE OF AIR PERMEABILITY BY WASHING

摘要

PROBLEM TO BE SOLVED: To provide a fabric with high air permeability and small change rate of air permeability after washing.SOLUTION: A fabric according to the present invention is the fabric composed of a synthetic fiber multifilament, wherein the synthetic fiber multifilament has a modified cross-section degree of 1.2-2.0, and includes a multi-lobar type single yarn having a convex portion and a concave portion of 3-12 in the outer shape of the fiber cross section, and has a single yarn group A having a contact part having a contact length of 2 μm or more with an adjacent multi-lobar type single yarn and a single yarn group B not having a contact part having a contact length of 2 μm or more with an adjacent multi-lobar type single yarn, the single yarn group A is 20-95% of the total number of the multi-lobar type single yarns included in the single yarn group A and the single yarn group B.SELECTED DRAWING: Figure 2
