Bulked yarn and wound yarn for production of woven or knit fabric, woven or knit fabric, and method for producing the same

A method for producing a woven or knit fabric from a bulked yarn comprising bulked single spun yarn, comprising:

• (a) dissolving and removing a water-soluble yarn from at least one composite twisted yarn comprising a single spun yarn and the water-soluble yarn, which are twisted together in a direction opposite to a twisting direction of the single spun yarn, in a hydrophilic solvent, to produce a bulked single spun yarn,
• wherein when a sample of the bulked yarn having a length of 100 cm is hung down in a state where both ends of the yarn are fixed at a distance of 10 cm from each other in a direction perpendicular to the direction of gravitational force, twisting does not occur or an average value of the distances from the uppermost end of a twisting section to the first and second fixed ends of the yarn is 30 cm or more;
• and
• (b) producing a woven or knit fabric comprising the bulked single spun yarn.
