Silk selection

The fineness of the core yarn and the number of filaments therein are selected according to the use of the fabric and the number of spinning counts. The core wire of the same denier, the finer the monofilament, the more the number of the root, the softer and smoother the fabric; on the contrary, the less the number of the fabric, the better the rigidity of the fabric. For the coated product, it is not necessary to consider the gloss of the core wire, and the optical core wire can be used to reduce the production cost; if the exposed product is produced, the gloss of the core wire should be considered, and the light wire is not used as much as possible, so that the product causes aurora and influence. Effect. For example, 11.8tex (50s) polyester-cotton core-spun yarn, skirting and shirt fabrics should be used as the core yarn of ordinary low-strength and high-stretch 5.56tex (50D)/24F semi-gloss polyester filament. When the core yarn is used as the sewing thread, high-strength low-stretch polyester filaments with a large number of single filaments of 7.78 tex (70D)/36F or more are generally used. When used as a burnt-out garment, a light-weight polyester filament of 7.56 tex (68D) / 36F or less can be used. However, for the core-spun yarn of burnt-out fabric, the fineness of the core wire should be mastered. Generally, 7.22-8.33tex (65-75D)/36F matt or semi-gloss polyester filament is used to prevent the burnt-out part from being too thin. , too thin and causing aurora. For core-spun yarns used in stretch fabrics, the fineness of the core yarn can be selected according to the use of the fabric. Polyester type 7.78 tex (70D) spandex yarn is generally used, and the draw ratio is preferably about 3.8 times. For medium-sized (medium-low-span) spandex core-spun yarns for warp-strength corduroy and stretch-clothing fabrics, the spandex yarns should be stretched to a larger extent, about 3.8-4.0 times, to ensure that the elastic pants are taken when the hips are The knee has a relatively resilient force.
