To obtain a lightweight fabric having touch feeling, excellent in swelling feeling and dry feeling and harshness and useful as a raw material from spring to summer by blending a fiber having high-shrinkage in boiling water with a fiber having low-shrinkage in boiling water among a modified cross section type hollow fiber.

Two kinds of yarns comprising a high-shrinkage fiber having ≥15% shrinkage in boiling water and a low-shrinkage fiber having ≤10% shrinkage in boiling water among a modified cross section type hollow fiber having 5-30% hollow ratio and 1.5-3.5 modified cross section degree are blended. A fabric is formed using the blended yarn and the resultant fabric is subjected to relax treatment and dyeing finishing to make the clearance between single yarns large.
