Abstract

A knitted fabric containing a composite yarn is provided, which is characterized in that the composite yarn is constituted of two or more kinds of false-twist crimped yarns and has a torque of not more than 30 T/m.

Claims (16)

1. A knitted fabric comprising a composite yarn, which is characterized in that the composite yarn is constituted of two or more kinds of false-twist crimped yarns and has a torque of not more than 30 T/m, the knitted fabric comprises a hydrophilizing agent, a percentage of crimp of the composite yarn is 2% or more, the composite yarn consists of polyethylene terephthalate fiber, and the composite yarn has a single yarn fineness of 0.00002 to 2.0 dtex and the composite yarn is an interlace-processed interlaced yarn wherein the number of interlaces falls within the range of from 50 to 90 nodes/m.

2. The knitted fabric according to claim 1 , wherein the composite yarn is constituted of a false-twist crimped yarn having S-direction torque and a false-twist crimped yarn having Z-direction torque.

3. The knitted fabric according to claim 1 , wherein the torque of the composite yarn is non-torque.

4. The knitted fabric according to claim 1 , wherein 0.1% by weight or more of an ultraviolet ray absorbent is contained in the polyethylene terephthalate fiber.

5. The knitted fabric according to claim 1 , wherein a cross-sectional shape of a single yarn fiber of the false-twist crimped yarn is a modified cross-section other than a round cross-section.

6. The knitted fabric according to claim 1 , wherein an ultraviolet ray shielding rate at a wavelength in the range of from 280 to 400 nm is 90% or more.

7. The knitted fabric according to claim 1 , wherein 0.2% by weight or more of a matting agent is contained in the polyethylene terephthalate fiber.

8. The knitted fabric according to claim 1 , wherein a visible light shielding rate at a wavelength in the range of from 400 to 700 nm is 60% or more.

9. The knitted fabric according to claim 1 , wherein a stitch density falls within the range of from 30 to 90 courses/2.54 cm and the range of from 30 to 90 wales/2.54 cm.

10. The knitted fabric according to claim 1 , wherein the knitted fabric has a multilayered structure having at least a surface layer and a back layer, and the composite yarn is disposed on the surface layer.

11. The knitted fabric according to claim 1 , wherein the knitted fabric has a round knitted fabric texture.

12. The knitted fabric according to claim 1 , wherein a stretchability in a lateral direction as measured according to JIS L1018 is 50% or more.

13. The knitted fabric according to claim 1 , wherein a recovery factor of stretchability in a lateral direction as measured according to JIS L1018 is 90% or more.

14. The knitted fabric according to claim 1 , wherein a snagging resistance as tested for 15 hours by using a hacksaw according to JIS L1058 D-3 Method is grade 3 or more.

15. Sports clothing comprising using the knitted fabric according to claim 1 .

16. Sports clothing comprising using the knitted fabric according to claim 2 .
