Abstract: Provided is a bulked yarn, comprising a bulked single spun yarn obtained from a composite twisted yarn comprising a single spun yarn and a water-soluble yarn, which are twisted together in a direction opposite to a twisting direction of the single spun yarn, by dissolving and removing the water-soluble yarn in a hydrophilic solvent from the composite twisted yarn. When 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.

Abstract: A bulked yarn comprising a bulked single spun yarn obtainable from a composite twisted yarn in which a single spun yarn and a water-soluble yarn together in a direction opposite to the twisting direction of the single spun yarn by dissolving and removing the water-soluble yarn in a hydrophilic solvent from the composite twisted yarn is prepared. When the bulked yarn with 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. The bulked yarn has excellent texture, lightweight properties, and anti-pilling properties, as well as excellent weaving and knitting properties and productivity.

Abstract: A textile includes a composite twisted yarn, including a spun yarn and a water-soluble yarn. The spun yarn has a twist direction that is a reverse of a twist direction of the composite twisted yarn. The water-soluble yarn is twisted with the spun yarn. A twist number of the composite twisted yarn is 1.3 to 3 times a twist number of the spun yarn, and a weight ratio of the spun yarn relative to the water-soluble yarn [spun yarn]/[water-soluble yarn] is 20/80 to 98/2. An other textile may also include an elongated elastic yarn having an elongation of 2 to 5 times an original length of the elastic yarn in a non-elongated position, and the elongated elastic yarn is twisted with the water-soluble yarn and the spun yarn. A twist number of the composite twisted yarn is 0.3 to 3 times a twist number of the spun yarn.

Abstract: To produce a textile or fabric having a high yarn strength and a high stretching property. The textile or fabric does not cause troubles such as a thread breakage even in weaving or knitting with a high-speed weaving or knitting machine. To prepare a composite twisted yarn which at least comprises a spun yarn and a water-soluble yarn twisted with the spun yarn, wherein the twist direction of the composite twisted yarn is reverse to the twist direction of the spun yarn, and the composite twisted yarn fulfils the following requirement (1) or (2) (1) the twist number of the composite twisted yarn is 1.
