Embodiment 1

[0016] A kind of dyeing process of nylon fabric, comprises the following steps:

[0017] (1) Blank pretreatment: put the newly produced nylon fabric to be dyed into a washing machine for washing, add 4g / L neutral detergent, the bath ratio is 1:30, the washing time is 10min, and the washing temperature is 30°C ;

[0018] (2) Presetting: Presetting the washed nylon fabric at 130°C; the presetting temperature should not be too high, otherwise it will affect the coloring speed;

[0019] (3) Jet dyeing and water washing: Use a CUT type jet dyeing machine to put the nylon fabric into water at 20-25 °C, add the auxiliary agent soda ash and the special degreasing agent HD-328, and the amount of soda ash added is 2g / L for special degreasing Adding agent HD-328 is 0.5g / L, add dye after running for 10min, adjust the pH between 4-6, run for 15min and then raise the temperature to 80℃ at a speed of 1℃ / min, keep warm and run for 40min and then cool down to room temperature; Take out and w...

Abstract

The invention discloses a nylon fabric dyeing technology. The technology adopts a process flow comprising the steps of blank pretreatment, presetting, jet dyeing, water washing, color fixation, water washing and air drying, the water washing and the high-temperature presetting treatments before dyeing make creases and wrinkles be difficultly formed in the dyeing process to obtain a special wrinkle effect, and the adoption of a jet dyeing machine for dying and the change cooperation addition of an assistant, a dye and the temperature effectively avoid variegation and color wrinkle phenomena and make the dyeing uniform and a finished product soft and fluffy, so the technology has a good coloring effect, is suitable for the large-scale industrial production and application, and has an improved market competiveness.

Description

technical field [0001] The invention relates to a fabric dyeing process, in particular to a nylon fabric dyeing process. Background technique [0002] With the change of people's consumption concept, the pursuit of clothing fabrics is very particular, not only soft to the touch, but also light and casual to wear. Nylon fabrics are soft and fluffy, uniquely smooth, and have good abrasion resistance. They have become the first choice for casual sports fabrics. However, the existing dyeing techniques for nylon fabrics are prone to uneven coloring, color wrinkles and other defects, which cannot satisfy consumers' high expectations for fabrics. Quality requirements, thereby limiting the popularization and application of nylon fabrics. [0003] Therefore, a new technical solution is needed to solve the above problems. Contents of the invention [0004] Purpose of the invention: In order to solve the problems existing in the prior art, the present invention provides a dyeing pr...
