## Abstract

An object of the present invention is to obtain a fabric having superior water absorbency and sweat absorption/rapid drying while having anti-pilling qualities and a cotton-like texture. A woven/knitted article and a textile product material with good aesthetic properties and functionality, and good general physical properties are obtained which have anti-pilling qualities not obtained in conventional fabrics having a high synthetic fiber blend ratio, and functionality such as water absorbency, water absorption/rapid drying, and quick drying after laundering, which cannot be obtained in conventional cotton fabrics. The present invention is a woven/knitted article comprising one or more fibers selected from synthetic fibers, regenerated fibers, and semisynthetic fibers, the woven/knitted article including a spun yarn, which contains mass % or more of an aliphatic polyamide short fiber A having a single-fiber fineness of 0.5 dtex to 5 dtex and a fiber length of 25 mm to 70 mm in the spun yarn, and having water absorbency evaluated using a falling-drop method of seconds or less; a method for manufacturing the woven/knitted article; and a textile product.

## Claims

### Claim 1

A woven/knitted article comprising one or more fibers selected from synthetic fibers, regenerated fibers, and semisynthetic fibers, the woven/knitted article including a spun yarn, which contains 30 mass % or more of an aliphatic polyamide short fiber A having a single-fiber fineness of 0.5 dtex to 5 dtex and a fiber length of 25 mm to 70 mm in the spun yarn, and having water absorbency evaluated using a falling-drop method of 10 seconds or less.

### Claim 2 (depends on 1)

The woven/knitted article according to claim 1, wherein the spun yarn has a cotton count of 2 to 60.

### Claim 3 (depends on 1)

The woven/knitted article according to claim 1, wherein a twist coefficient of the spun yarn is 3.5 to 5.

### Claim 4 (depends on 1)

The woven/knitted article according to claim 1, wherein a basis weight is 50 to 600 g/m2.

### Claim 5 (depends on 1)

The woven/knitted article according to claim 1, comprising a fiber B other than the aliphatic polyamide short fiber.

### Claim 6 (depends on 5)

The woven/knitted article according to claim 5, wherein the fiber B is one or more selected from a polyester-based fiber and a polyurethane fiber.

### Claim 7 (depends on 5)

The woven/knitted article according to claim 5, wherein the fiber B includes a modified cross-sectional fiber.

### Claim 8 (depends on 5)

The woven/knitted article according to claim 5, wherein 20% or more of the fiber B is exposed on one surface of the woven/knitted article.

### Claim 9 (depends on 5)

The woven/knitted article according to claim 5, wherein the fiber B includes a fiber having a color different from the color of the aliphatic polyamide short fiber.

### Claim 10 (depends on 1)

The woven/knitted article according to claim 1, wherein the spun yarn is one or more spun yarns selected from a ring spun yarn or a compact spun yarn, a siro spun yarn, a siro-compact spun yarn, an MVS spun yarn, and an air spun yarn.

### Claim 11 (depends on 1)

The woven/knitted article according to claim 1, wherein a surface has anti-pilling qualities of Grade 4 or higher in accordance with Method A of JIS L 1076 (2006).

### Claim 12 (depends on 1)

The woven/knitted article according to claim 1, wherein a diffusive residual moisture ratio after 60 minutes is 40% or less before washing and after washing 10 times.

### Claim 13 (depends on 1)

A textile product comprising the woven/knitted article according to claim 1.

### Claim 14 (depends on 1)

A method for manufacturing the woven/knitted article according to claim 1, comprising a step of knitting and weaving a fiber including a spun yarn, which contains 30 mass % or more of an aliphatic polyamide short fiber having a single-fiber fineness of 0.5 to 5 dtex and a fiber length of 25 mm to 70 mm, wherein the method further satisfies the following (1) and/or (2),
(1) the method includes a step of water absorption processing, and
(2) the fiber includes a modified cross-sectional fiber.

### Claim 15 (depends on 14)

The method for manufacturing the woven/knitted article according to claim 14, wherein the aliphatic polyamide short fiber has a raw stock elongation of 10% to 70%.
