Abstract

Provided is a pile fabric that can provide both a soft touch feel and durability (pile retention and/or suppression of pile loss). The pile fabric is provided with a base structure formed from a warp and weft and a loop pile formed from pile yarn. The pile yarn is twisted yarn with a twist factor of 2.0 or greater. When the pile yarn is untwisted yarn or weakly twisted yarn, insoluble yarn prior to water soluble yarn elimination is twisted yarn with a twist factor of 2.0 or greater. The proportion of pile height to pile yarn diameter is 40× or greater. The gap between adjacent pile yarn strands is 0.5 mm or less. The pile yarn is 50-120 English yarn count. The loop pile has snarling, and the snarling for adjacent piles is entangled.

Claims (35)

1 . A pile fabric for towel cloth comprising:

a base weave construction formed of a warp yarn and a weft yarn, and a plurality of loop piles formed from a pile yarn by weaving the pile yarn and the weft yarn;

wherein a ratio of a height of each of the loop piles to a diameter of the pile yarn is 51 times or greater, and the height of each of the loop piles is between 6.3 mm and 12 mm;

wherein the pile yarn is a twisted yarn made of cotton fibers and having a twisting coefficient of 2.0 or greater;

wherein each of the loop piles has a standup portion and a return portion, the pile yarn of the plurality of loop piles is twisted in the loop pile, the standup portion and the returning portion intersect to form an annular shape with an intersection point, a snarl is formed from the intersection point and the annular shape; and

wherein the pile yarn has an English yarn count of a range between 50 and 120.

2 . The pile fabric according to claim 1 :

wherein the plurality of the pile yarns is arranged in parallel with the warp yarn; and

wherein a gap between neighboring pile yarns is not greater than 0.5 mm.

3 . The pile fabric according to claim 2 :

wherein the snarls on the neighboring loop piles entwine together.

4 . The pile fabric according to claim 2 , wherein the plurality of the pile yarns is arranged between a neighboring warp yarns.

5 . A manufacturing method of the pile fabric according to claim 4 :

wherein the plurality of the pile yarns to be arranged between the neighboring warp yarns is drawn through the same dent of a reed for weaving; and

wherein snarls are formed after weaving, and the snarls on the neighboring loop piles entwine together.

6 . A pile fabric for towel cloth comprising:

a base weave construction formed of a warp yarn and a weft yarn, and a plurality of loop piles formed from a pile yarn by weaving the pile yarn and the weft yarn;

wherein a ratio of a height of each of the loop piles to a diameter of the pile yarn is 51 times or greater, and the height of each of the loop piles is between 6.3 mm and 12 mm;

wherein the pile yarn is a non-twisted yarn made of cotton fibers or a soft twist yarn made of cotton fibers;

wherein each of the loop piles has a standup portion and a return portion, the pile yarn of the plurality of loop piles is twisted in the loop pile, the standup portion and the returning portion intersect to form an annular shape with an intersection point, a snarl is formed from the intersection point and the annular shape; and

wherein the pile yarn has an English yarn count of a range between 50 and 120.

7 . The pile fabric according to claim 6 :

wherein the plurality of the pile yarns is arranged in parallel with the warp yarn; and

wherein a gap between neighboring pile yarns is not greater than 0.5 mm.

8 . The pile fabric according to claim 7 :

wherein the snarls on the neighboring loop piles entwine together.

9 . The pile fabric according to claim 7 , wherein the plurality of the pile yarns is arranged between the neighboring warp yarns.

10 . A manufacturing method of the pile fabric according to claim 9 :

wherein the plurality of the pile yarns to be arranged between the neighboring warp yarns is drawn through the same dent of a reed for weaving; and

wherein snarls are formed after weaving, and the snarls on the neighboring loop piles entwine together.

11 . A manufacturing method of the pile fabric according to claim 6 :

wherein, in a conjugated yarn as the pile yarn, a water-soluble yarn is twisted in a direction reverse to a water-insoluble twisted yarn;

wherein the water-insoluble twisted yarn is a twisted yarn having a twisting coefficient of 2.0 or greater;

wherein the conjugated yarn is woven such that the plurality of loop piles are formed;

wherein the pile yarn is formed by removing the water-soluble yarn.
