Abstract

To provide towel cloth which has favorable pile uprightness, erectility of pile, and bulkiness, and has both a fluffy hand and a dry touch, and moreover which hardly drops fluff, and a manufacturing method of such towel cloth. Towel cloth constituted by locking a pile yarn to a ground yarn, wherein the pile yarn has two or more single yarns which are initially twisted in a same direction and which are subsequently twisted in an opposite direction to the initial twist.

Claims (13)

1. Towel cloth constituted by locking pile yarns to a ground yarn, wherein

each of the pile yarns consists of two paralleled air-spun single yarns of 100% cotton, each air-spun single yarn being initially twisted in the same first direction, and

each of the pile yarns is structured such that the two paralleled air-spun single yarns are integrally twisted in a second direction opposite to the first direction, wherein a number of integral twists in the second direction ranges from 20% to 80% of a number of initial twists in the first direction such that the pile yarns comprise a plurality of accumulated twists and voids located between the two paralleled air-spun single yarns, the voids being located between respective accumulated twists.

2. The towel cloth according to claim 1 , wherein a yarn count of the two paralleled air-spun single yarns is 8 to 120.

3. The towel cloth according to claim 1 , wherein a basis weight of the towel cloth is 100 to 1000 g/m 2 .

4. A manufacturing method of towel cloth constituted by locking pile yarns, the method comprising:

a step of paralleling two air-spun single yarns of 100% cotton yarn, each air-spun single yarn being a fiber initially twisted in the same first direction;

a step of untwisting the two paralleled air-spun single yarns by a subsequent twist in a second direction opposite to the first direction of the initial twist to form the pile yarn, wherein a number of integral twists in the second direction ranges from 20% to 80% of a number of initial twists in the first direction such that the pile yarns comprise a plurality of accumulated twists and voids located between the two paralleled air-spun single yarns, the voids being located between respective accumulated twists; and

a step of locking the pile yarns to a ground yarn in which a warp ground yarn and a weft ground yarn intersect each other.

5. The towel cloth according to claim 2 , wherein a basis weight of the towel cloth is 100 to 1000 g/m 2 .

6. The towel cloth according to claim 1 , wherein a basis weight of the towel cloth is 100 to 1000 g/m 2 .

7. The towel cloth according to claim 1 , wherein the number of integral twists in the second direction ranges from 46% to 50% of the number of initial twists in the first direction.

8. The towel cloth according to claim 1 , wherein each of the two paralleled air-spun single yarns is a core-in-sheath air spun yarn in which a core of the air-spun single yarn is a parallel fiber portion constituting 20% to 30% of the air-spun single yarn.
