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

Abstract

A method for producing warp and weft double-elastic denim fabric with a beam line. The warp and weft double-elastic denim fabric is produced in a long process by dyeing the beam line in multiple dyeing vats; process steps: (1) use cotton-wrapped spandex slubs as warp yarns, and use cotton as weft yarns Three packs of polyester-coated and spandex-wrapped yarns are used as weft yarns; (2) The ball warping process maintains a stable temperature and humidity throughout; (3) Heavy hammers are used to pressurize, and pretreatment is carried out before dyeing until the tension of each part is stable. , and then connected to the elastic ball shaft; the dyeing process adopts a low-content dyeing process with multiple dye vats to increase the penetration and dyeing rate of the dye; (4) the dividing process adopts small tension; (5) the sizing adopts low viscosity and low Thick sizing process; (6) Weaving adopts high back beam, large tension and small opening machine process; (7) Finishing adopts desizing and pre-shrinking finishing process; (8) Adopts the method of shaping. The latitude and longitude double-elastic denim produced by the invention has bright and uniform color, high color fastness and stable 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...

Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific embodiment:

[0026] 1. The technical problem to be solved by the present invention:

[0027] 1.1 Due to the high elasticity of the warp yarn, there are many processes through, especially on the premise that there is no experience in producing warp and weft double-elastic denim fabrics with beam threads, how to control the tension of each process and the elasticity of the elastic yarn is stable and consistent is the key;

[0028] 1.2 Use the beam line to produce warp and weft double-elastic denim to solve the problems of light color, large flower degree and poor color fastness, and broaden the thinking for the deep processing of clothing washing;

[0029] 1.3 The control of elastic stability and dimensional stability of warp and weft double-elastic denim is another major problem for this fabric.

[0030] 2. The specific process steps of warp and weft double elastic denim production:
