[0008] In the weft knitted fabric with hidden horizontal bar effect provided by the utility model, the fineness of the paper yarn can be 25-26S.

[0009] In the weft knitted fabric with hidden horizontal bar effect provided by the utility model, the fineness of the paper yarn can be 25-26S.

[0010] In the weft knitted fabric with hidden horizontal bar effect provided by the utility model, the fineness of the paper yarn can be 25-26S.

[0011] In the weft knitted fabric with hidden horizontal bar effect provided by the utility model, the fineness of the paper yarn can be 25-26S.

[0012] In the weft knitted fabric with hidden horizontal bar effect provided by the utility model, the fineness of the paper yarn can be 25-26S.

[0013] In the weft-knitted fabric with hidden horizontal stripe effect, the weft-knitted fabric has the following features: the weft-knitted fabric is alternately knitted with 4 horizontal lines as a minimum cycle, and the cycle knitting is performed by 1 tight and hard weft plain-knitted loop horizontal line, 1 loose and soft weft plain-knitted loop horizontal line, 1 tight and soft weft plain-knitted loop horizontal line and 1 loose and soft weft plain-knitted loop horizontal line.

[0014] In the weft-knitted fabric with hidden horizontal stripe effect, the weft-knitted fabric has the following features: the weft-knitted fabric has a square meter weight of 190-230 grams per square meter.

[0015] Compared with the prior art, the weft-knitted fabric with hidden horizontal stripe effect has the following advantages:

[0016] (1) The fabric surface is flat and has the styles of hard and soft fabrics.

[0017] The paper yarn has low strength and elongation rate and is hard and stiff, has high moisture regain and good hygroscopicity, the modified polyester supercool fiber has high strength and elongation rate and is soft, and has relatively small hygroscopicity, the paper yarn and the fine modified polyester supercool yarn with the same twist direction are arranged in parallel as a core yarn assembly, the paper composite yarn is prepared by wrapping and winding the fine denier modified polyester supercool filament with the opposite twist direction and the lower twist degree, the proportion of the paper yarn in the paper composite yarn is greater than 50%, the fineness is 15-16S, and the paper yarn can better reflect the stiff hand feeling in the fabric; the modified polyester supercool yarn has good flexibility, and if the paper composite yarn with different flexibility and hygroscopicity and the modified polyester supercool yarn are alternately knitted in continuous number of horizontal lines, the fabric surface will be distorted and uneven. The weft-knitted fabric is prepared by alternately knitting the modified polyester supercool yarns with two different finenesses of 15-16S and 30-32S and the paper composite yarn with the fineness of 15-16S, the internal stress of the fabric is balanced, the fabric surface is flat and has no distortion and skew phenomenon, and the weft-knitted fabric has the styles of stiff paper yarn and soft modified polyester supercool yarn.

[0018] (2) The fabric appearance has a hidden horizontal stripe style effect.

[0019] The weft plain stitch is selected, and four horizontal lines are continuously knitted as a minimum cycle, that is, 15-16S paper composite yarn is knitted to form a horizontal line of relatively tight and stiff weft plain stitch, 30-32S modified polyester supercool yarn is knitted to form a horizontal line of relatively loose and soft weft plain stitch, 15-16S modified polyester supercool yarn is knitted to form a horizontal line of relatively tight and soft weft plain stitch, and 30-32S modified polyester supercool yarn is knitted to form a horizontal line of relatively loose and soft weft plain stitch, wherein the relatively tight and stiff weft plain stitch horizontal line and the relatively tight and soft weft plain stitch horizontal line are highlighted on the surface of the fabric, and the relatively loose and soft weft plain stitch horizontal line is recessed on the surface of the fabric, thereby forming a hidden horizontal stripe effect of a one-by-one horizontal line recessed and protruded stitch structure on the surface of the fabric. The rigidity and flexibility of the paper yarn and the modified polyester supercool fiber are different, the hard and soft touch of the paper composite yarn and the modified polyester supercool yarn is different, thereby forming a hidden horizontal stripe with a 1:3 different touch. Because the moisture absorption of the paper yarn and the modified polyester supercool yarn is different, the dyeing rate of the dye during the same bath dyeing of the fabric is different, and the paper composite yarn usually forms a stitch horizontal line and the modified polyester supercool yarn forms a stitch horizontal line, which causes a slight lightness color difference on the fabric surface due to the inconsistent color rate, thereby forming a color difference horizontal stripe effect with one horizontal line and three horizontal lines not obvious.

[0020] (3) The fabric has the functions of moisture absorption, quick drying, ultraviolet protection, antibacterial and bacteriostatic.

[0021] Paper yarn is light and hygroscopic, and paper yarn textiles have the style characteristics of hard and dry touch, and have certain antibacterial and deodorization performance. The modified polyester supercool is grafted with hydrophilic groups on the polyethylene terephthalate high molecular chain, adopts Y-shaped cross section and micro-groove aperture physical form structure, so that it has excellent moisture absorption, moisture conduction and quick drying performance. When the fiber occupies a certain mass ratio in the fabric, the moisture absorption, moisture wicking and quick drying functions can be achieved without the need of auxiliary finishing; because the grafted hydrophilic groups have good antibacterial properties, combined with the excellent moisture absorption and quick drying properties of the fiber, a dry environment is created in which bacteria are not easy to breed, so that the supercool fabric has certain antibacterial effect, the fiber does not contain any silver and other heavy metals, and the moisture absorption, quick drying and antibacterial functions are durable. Therefore, the fabric prepared from paper yarn and modified polyester supercool has moisture absorption, quick drying and antibacterial functions. The anti-ultraviolet function of the fabric is comprehensively affected by many factors such as fiber raw material, fabric organization and structure parameters, and the relatively close loop horizontal row of the fabric of the utility model is helpful to improve the anti-ultraviolet function. In the utility model, the proportion of paper yarn in the paper composite yarn is about 58-62%, and the proportion of paper yarn and modified polyester supercool fiber in the fabric is about 19-23%:81-77%. The fabric prepared therefrom has the comprehensive performance of the two different materials, retains the smooth and crisp style of paper yarn and the soft touch of modified polyester supercool fiber, and has multiple functions such as moisture absorption, quick drying, anti-ultraviolet and antibacterial.

[0022] (4) The square meter weight of the fabric and the proportion of paper yarn can be conveniently controlled.

[0023] The modified polyester supercool fiber has high strength and elongation and good flexibility, and can be conveniently prepared into 15-60S knitted yarns of different specifications by using the siro compact spinning technology, so as to meet the requirements of smooth knitting of the circular knitting machine. The utility model adopts the weft plain stitch structure to circularly weave four routes of different yarns and different finenesses, and the modified polyester supercool yarns and paper composite yarns of different finenesses are alternately woven, so as to conveniently control the square meter weight of the fabric and the mass ratio of paper yarn in the fabric. For example, in the four horizontal row minimum cycle alternate weaving of weft plain knitted fabric, one horizontal row is 16S paper composite yarn, one horizontal row is 32S modified polyester supercool yarn, one horizontal row is 16S modified polyester supercool yarn, and one horizontal row is 32S modified polyester supercool yarn, the square meter weight of the fabric is about 220g / m2, and the proportion of paper yarn in the fabric is about 20%; in the four horizontal row minimum cycle alternate weaving of weft plain knitted fabric, one horizontal row is 15S paper composite yarn, and three horizontal rows are 30S modified polyester supercool yarns, the square meter weight of the fabric is about 190g / m2, and the proportion of paper yarn in the fabric is about 23%.
