Designing the weft and weft density of the fabric should also be combined with the use of the fabric. For example, the enamel fabric is characterized by being light and transparent, and in order to maintain this characteristic, the warp and weft density should be reduced in addition to the finer weft and weft yarns. In order to maintain good elasticity of the fabric, not to weaken, not to split, the warp and weft density tends to balance as much as possible, and give the latitude and longitude filaments more twist. For another example, when designing the horn fabric, the warp and weft density should be minimized so as not to affect the sound quality and maintain excellent air permeability. Another example is the use of various decorative silk paste, such as the Chinese painting armor used, book binding fabrics, paste wall silk, gift boxes and other brocade, under the premise of ensuring the decorative effect, can greatly reduce the warp and weft density. In contrast, silk taffeta used to make high-end gowns is usually denser and stiffer, and it fully reflects the unique "silk" characteristics of real silk. The density of the fabric is usually higher than that of ordinary plain weave fabrics. The theoretical density can be deduced from the interweave of the diameter of the filaments and the structure of the structure (the wool fabric has already been introduced), but this calculation density is not completely practical, because the production conditions of the production units are different, and the above five kinds of density design There are influential factors that cause a certain difference in actual density. In the actual production process, the weft density of the fabric is smaller than the density, mainly because: the material used for the warp is better, the tension on the machine is large, the yarn is smooth, and the silk is enough, which has a great influence on the texture of the fabric. The warp thread density is generally smaller than that of the weft thread, which is advantageous for improving the production efficiency. At the same speed, the weft density is small and the yield is high. In addition, the small weft density is convenient for production, and it is convenient to disassemble the weft when the weaving hammer is produced. The ratio of density to weft density should be based on the linear density of the warp and weft yarns, the organizational structure, and the characteristics of the fabrics used. Such as the georgette's warp and weft density ratio is very close, generally not less than 10%, but the density of a large satin fabric. The ratio of the warp and weft density varies by 50% to 60%. From the point of view of the design of new varieties, if there is no special requirement, the weft density of plain weave fabrics should be less than 20%-30% of the density, 30%-40% of twill, and 50% of satin. If the weft density of a single-layer fabric is greater than the density, it is unreasonable and should be avoided. However, weft fabrics, especially jacquard fabrics composed of multicolor wefts, may have greater weft densities than densities. This is a structural requirement and can be treated as a special case.
