Claims

1. A composite false twist yarn comprising polyamide fiber A and polyamide fiber B, wherein the aforementioned polyamide fiber A is a potential crimped yarn and the aforementioned polyamide fiber B is not a potential crimped yarn, and the ratio of adjacent filament groups of the aforementioned polyamide fiber A is more than 50%; The adjacent filament group refers to an aggregate of adjacent and connected single fibers of potential crimp yarns with a total number of N×0.2 or more in the cross-section of the composite false twist yarn. The ratio of adjacent filament groups of potential crimp yarns refers to the value expressed as Ns / N×100, which is a percentage of the total number of single fibers of potential crimp yarns constituting the adjacent filament group, when the total number of single fibers of potential crimp yarns constituting the adjacent filament group is Ns.

2. The composite false-twist yarn according to claim 1, wherein, The difference in elongation between the aforementioned polyamide fiber A and the aforementioned polyamide fiber B is more than 7.0% and less than 40.0%.

3. The composite false-twist yarn according to claim 1, wherein, The monofilament fineness of the aforementioned polyamide fiber B is above 0.3 dtex and below 0.9 dtex.

4. The composite false-twist yarn according to claim 1, wherein, The aforementioned polyamide fiber A is an eccentric core-sheath type composite fiber with an equilibrium moisture content of less than 6.3%, and the viscosity ratio of the polyamide constituting the core component to the polyamide constituting the sheath component is greater than 1.20 and less than 1.

40.

5. A woven or knitted fabric, at least a portion of which comprises a composite false-twist yarn exhibiting crimp as described in any one of claims 1 to 4.

6. Clothing, at least a portion of which comprises a composite false-twist yarn exhibiting curl as described in any one of claims 1 to 4.

7. Clothing, at least a portion of which comprises the woven or knitted fabric of claim 5.
