Method for producing warp and weft dual-elastic denim fabric by bundled lines

Abstract

The invention discloses a method for producing a warp and weft dual-elastic denim fabric by bundled lines. The warp and weft dual-elastic denim fabric is produced by a long technological process through dyeing of a plurality of dyeing cylinders for the bundled lines. The method comprises the following steps of: (1) making warp yarns by cotton-wrapped spandex bamboo joints, and making weft yarns by triple wrapped yarns formed by wrapping cotton on terylene and then wrapping the cotton-wrapped terylene on spandex; (2) always keeping stable temperature and humidity in a ball warp working procedure; (3) performing pressurization by a heavy hammer, before dyeing is executed, performing pretreatment until tension of each part is stable, then implementing an elastic ball shaft connection method, wherein the dyeing process is a multi-dyeing-cylinder low-content dyeing process, so that the penetration and the dyeing rate of a dye can be improved; (4) performing a weft division process by low tension; (5) slashing by a sizing process with low viscosity and low concentration; (6) weaving by a feeding process with a high rear beam, high tension and a small opening; (7) arranging by a desizing pre-contraction arrangement process; and (8) treating by adopting a sizing method. The warp and weft dual-elastic denim fabric produced by the method is bright and uniform in color, relatively high in color fastness and similarly stable in elasticity.

Description

technical field [0001] The invention relates to the technical field of textiles, and relates to a method for producing warp and weft double-elastic denim fabric with bundled threads. Background technique [0002] With the development of society and economy, people's economic living standards are gradually improving, and their requirements for their own clothing are getting higher and higher. In terms of appearance, they must not only be beautiful and tidy, but also comfortable and decent. In order to cater to the aesthetic psychology of consumers In recent years, various fabric manufacturers have chosen their favorites, researched and produced warp and weft double-stretch denim fabrics, which are comfortable and decent to wear, especially for lesbians, showing the beauty of the lines, wearing no discounts, and wearing flat, clean and generous without knees. Due to the longitudinal elasticity of the fabric, how to control the shrinkage and stability of the elastic yarn during...

Problems solved by technology

Almost all manufacturers adopt short-process combined machine lines for production, and the products produced by combined machine lines are generally light in color, poor in color fastness, and have the disadvantages of large flowers after washing, which brings certain problems to the deep processing of garment washing. difficulty
