Production process of double-layer four-surface elastic fabric

Abstract

The invention discloses a production process of a double-layer four-surface elastic fabric. The production process includes the steps: S1 yarn selection; S2 warping; S3 weaving; S4 gray fabric pretreatment; S5 mechanical softening; S6 gray fabric presetting; S7 dyeing by a two-bath method; S8 post-finishing and setting. Nylon filaments serve as a coating layer, spandex serves as a first covering yarn of a core yarn, the first covering yarn serves as wrap yarns and weft yarns of a surface layer of the double-layer fabric, the content of the spandex is 6%, natural silks and Coolmax fibers serveas a coating layer, spandex serves as a second covering yarn of a core yarn, and the second covering yarn serves as wrap yarns and weft yarns of a inner layer of the double-layer fabric. According tothe production process of the double-layer four-surface elastic fabric, the surface layer is provided with a nylon covering yarn, the inner layer is provided with a covering yarn of the natural silksand the Coolmax fibers, so that the surface layer of the double-layer elastic fabric has the advantages of good abrasion resistance, high strength and the like of nylon wires, the inner layer of the elastic fabric has the advantages of good moisture absorption and perspiration and the like, and comfort of the fabric is improved.

Description

technical field [0001] The invention relates to the technical field of textile fabric production, in particular to a production process of a double-layer four-way elastic fabric. Background technique [0002] The four-way stretch fabric as casual trousers requires softness, comfort, good hygroscopicity, high color saturation, and purity. At the same time, it requires wear resistance, high strength, and no pilling. Although traditional cotton and linen natural fiber fabrics have the characteristics of softness, comfort and moisture absorption, dark colors, especially black, may appear whitish and have insufficient depth. Sensitive colors such as navy blue, wine red, black, dark gray, etc. have lightfastness and perspiration Poor fastness, changes in color and light after exposure to sunlight; polyester and nylon chemical fiber fabrics have the characteristics of wear resistance and good dimensional stability, but they have poor hygroscopicity, are prone to static electricity,...

Problems solved by technology

Although traditional cotton and linen natural fiber fabrics have the characteristics of softness, comfort and moisture absorption, dark colors, especially black, may appear whitish and have insufficient depth. Sensitive colors such as navy blue, wine red, black, dark gray, etc. have lightfastness and perspiration Poor fastness, changes in color and light after exposure to sunlight; polyester and nylon chemical fiber fabrics have the characteristics of wear resistance and good dimensional stability, but they have poor hygroscopicity, are prone to static electricity, and are uncomfortable next to the skin, and have poor color fastness to water and perspiration.

These problems have greatly restricted the production of fabrics, and the excellent properties of each fiber cannot be fully utilized, especially in the case of double-layer four-way stretch fabrics, the characteristics of poor moisture absorption and drainage of nylon fibers are particularly obvious
