    • PROBLEM TO BE SOLVED: To provide a light-weight woven fabric and a clothing material having excellent water repellency, high tearing strength and light weight. SOLUTION: The light-weight woven fabric has a fabric weight of ≤90 g/m 2 , includes a composite yarn obtained by using a polyester filament A having a single fiber fineness of ≥0.8 dtex and a polyester filament B having a single fiber fineness of ≤0.6 dtex and has a yarn length difference defined below of ≥8%. A composite yarn is extracted from the woven fabric, a weight of 0.1 cN (0.1 g)×(total fineness (dtex) of the composite yarn) is attached to the yarn, the yarn is cut to 5 cm long, the polyester filament A (single yarn) and the polyester filament B (single yarn) are taken out from the cut composite yarn, a weight of 0.1 cN (0.1 g)×(single fiber fineness (dtex)) is applied to each filament, the length of the filament is measured, and the yarn length difference (%) is calculated by the following formula: (yarn length difference (%))=(LB-LA)/LA×100 wherein LA is the yarn length (cm) of the polyester filament A, and LB is the yarn length (cm) of the polyester filament B.

    • PROBLEM TO BE SOLVED: To provide a crimped yarn produced by using a polylactic acid which is an eco-friendly material, free from the defects of polylactic acid comprising poor crimp tendency, bulkiness and abrasion resistance, and suitable as a carpet.
      SOLUTION: The crimped yarn is a multifilament yarn comprises a sheath-core conjugate fiber comprising a core component composed of a polylactic acid composition, and a sheath component composed of a polyamide composition, wherein the ratio of the core component is 10-50 wt.%, the noncircularity (C) of the core component is 1.2-9, the noncircularity (S) of the sheath component is 2-6, and the ratio of the noncircularity (C) of the core component to the noncircularity (S) of the sheath component (C/S) is 0.6-1.5. The invention further provides a carpet produced by using the crimped yarn.

    • PROBLEM TO BE SOLVED: To provide a fabric such as a woven or knitted fabric, containing a polytrimethylene terephthalate partially hollow fiber, and having excellent heat retaining properties, lightweight, bounce feeling and tear resistance.
      SOLUTION: The fabric composed of the polytrimethylene terephthalate partially hollow fiber includes the polytrimethylene terephthalate partially hollow fiber obtained by eluting a part of a core component from the tip part of a core-sheath type conjugate fiber having the tip part. The polytrimethylene terephthalate partially hollow fiber satisfies the following requirements (1) to (3): (1) ≥20% and ≤85% average percentage of hollowness; (2) ≥30% and ≤85% percentage of hollowness at the hollow part; and (3) ≥5 crimps/cm of the number of crimps in a single fiber.
