Different fabric organization requirements for yarn quality Due to the different structure of the fabric, the requirements for the rate of appearance of the yarns and yarns on the surface of the yarn used for weaving vary. In general, extra-fine fabrics are more demanding than medium-to-coarse fabrics in plain cotton fabrics; plain fabrics are more demanding than twill fabrics; and thin fabrics are more demanding than fabrics. 1. Yarn quality requirements for plain weave The density ratio of warp and weft yarns on plain weave fabrics is generally close. The fabric is flat and the fabric organization is 1/1. Therefore, the requirements for the warp and weft yarns are relatively high. Among them, the unevenness of the misalignment, rough warp and weft yarns is more stringent. . 2. Poplin fabric The poplin fabric has a high density and low weft density. The surface of the warp yarn floats in a granular form, and the fabric organization is 1/1. It has high requirements for warp yarn strength and strict requirements for weft yarns, bamboo knots and neps. Twill fabric Twill weave fabrics are densely organized, high in density, low in weft density, and have a nice cloth with a clear diagonal pattern. Fabric texture is 2/1, 3/1, and 2/2. It has high requirements on the strength and stripe of warp yarns, and strict requirements on the stems and nep of weft yarns. 4. The satin fabric (1) Zhigong: The front of the tribute fabric is mainly formed by warp yarns. There are often five three-flying yarns and five two-flying yarns. The fabric is thick and the fabric has a tight twill effect. There are still soft and smooth requirements. The fabric has 5/3, 5/2 surface satin. The main feature of the tribute fabrics is that most of the warp yarns appear on the front of the fabric, and the quality of the warp yarns is relatively high (such as tightening of the menstruation, loosening, neps, and feet, etc.). (2) Henggong: The front of Yokogawa fabric is mainly formed by weft yarns. The fabric is soft and smooth. The fabric is a 5/3 weft satin. The main characteristic of Henggong is that most of the weft yarns appear on the front side of the cloth, and the quality of the weft yarns is relatively high (such as nep, weft, etc.). 5. Extra fine fabric Extra-fine fabrics refer to fabrics whose wefts and wefts are below 10 tex (60 brbrons and above), and most of them are combed cotton yarns. Most of the fabrics are high-end products. Due to the finer yarns and the higher quality requirements of fabrics, yarns such as rovings, bamboo knots, strips, neps, oil yarns, colored yarns, and coal-gray yarns are required to be extremely strict. 6. Thin fabric Thin fabric means that the warp yarn tightness and weft yarn tightness of the fabric are all below 50%, especially the weft yarns are tightly arranged at 45% and below. Due to the thin density of warp and weft yarns, various defects have a high rate of appearance on the surface of the cloth, especially the weirs in the weft direction, such as bar stems, coarse wefts, bamboo knots, etc., are even more prominent. 7. Colored fabrics (1) Mitengbu: Mitengbu is usually a cloth that is woven into a colored yarn and a white yarn (or two different colors of warp yarns). It also has a color yarn in the warp and weft directions. And a white yarn (or two different colors of warp and weft) weaving. Because of the weaving characteristics of the yarns, the yarns are exposed on the cloth surface, and the requirements for the dryness, hairiness and nep of the yarn used are high. (2) Youth cloth: youth cloth is usually woven from a warp yarn and a white yarn in the weft direction. The warp and weft yarns have the same thickness. The youth cloth is similar to the meter cloth. Because the yarn curtain is exposed, the cotton yarn is exposed. The knot demand is high. 8. Polyester/cotton/cotton/polyester fabric Cotton/ polyester / poly / cotton fabrics are uniform because of the uniform filaments of the polyester filaments. They are strongly contrasted with the cotton yarns, and the yarns are exposed and prominent. Especially when single dyeing is performed, the requirements for cotton yarns, nep, strips, and hairiness are very high. high. 2 No need for weaving tightness for yarn quality Due to the difference in the structure of the fabric, the weaving tightness of different tissue fabrics will also vary. Different weaving tensions impose different requirements on the quality of the yarn. According to the degree of fabric tightness to determine the ease of fabric weaving: Tightness = warp / twist warp + weft / weft yarn Plain 1/1 more than 38 difficulty Twill 2/1 more than 42 difficulty Khaki and double oblique 2/2 3/1 over 45 difficulty Satin 4/1 more than 47 difficulty Difficult fabrics use strong yarns on the machine, and dense and available three- and four-inlets. 3 Requirements of yarn quality for different printing and dyeing processes Bleached blank After the fabric is bleached, the fabric surface is clear and white, so the residual defects on the surface of the fabric are more likely to appear, especially some oils, colored defects (such as bamboo, oil yarn, oil yarn, colored yarn, coal ash yarn, "three Silk and foreign fibers must pay special attention. Chemical fiber blended and pure-spinning products have higher requirements for the above defects because of their higher whiteness. 2. Printing blank Printed blanks can be broadly divided into two types, dyed bottom printing and white printing. Dyeing at the end of the printing due to the color pattern printed on the surface of the cloth, for the general surface of the greasy cloth , colored yarn, oil yarn, coal ash yarn, uneven yarn and other yarn defects and some weaving 疵 can be covered; white Because of the relatively large amount of whiteness on the surface of the printed fabric, the requirements for the above-mentioned yarn defect are strict, and sometimes it is even required to be equivalent to that of the bleached blank. 3. Staining blank Staining blanks are divided into two categories: light color blanks and dark color blanks. Due to the light color of light-colored blanks, for the oil stain on the surface, the requirements for yarns such as colored yarns, oil yarns, coal-gloss yarns, “three-wire†yarns, and foreign fibers are relatively high; deep-colored blanks are dyed darker for dyed yarns and oils. Yarn, coal ash yarns, uneven yarns, and other yarns are highly concealable, but require high demands for yarns such as snakeskin, nep, and dead cotton. Conclusion: There is no absolute difference between yarns and yarns. Suitable yarns are used to make the best use of cloths. This will not only result in excess quality, but also satisfy the basic needs of customers.
