Problems solved by technology

Although this technical process is shortened and the dyeing effect is better, the liquid-carrying rate applied to the fabric 42 by the padding process in the process of padding dyeing liquor and lye is generally 60-120%. Under these conditions, controlling the subsequent low-humidity baking conditions (humidity 20-35%, temperature 120-140°C) is a waste of energy, and the control of temperature and humidity is also relatively difficult, especially when the thickness of the fabric is different, which will cause banding. Large fluctuations in the humidity and temperature of the baking device require complex equipment for precise humidity and temperature control and rich operating experience
Due to this method, it is difficult to control the stability of low-humidity baking conditions, so this process has strict restrictions on the selection of reactive dyes, and requires strict detection and control of the temperature and humidity in the box, and the investment in equipment is large.

Abstract

The invention relates to a foam spraying dyeing method adopting reactive dyes, which comprises the following steps: mixing a reactive dye liquor and a color fixing liquid; applying the mixed liquor to a fabric; and carrying out water washing after fixing the color of the fabric. The method is characterized in that the mixed liquor is foamed before being applied to the fabric, and is applied to the fabric in a foamed manner. The foam spraying dyeing method has the advantages that the stability for controlling the dyeing process is improved; the process flow is short; energy and dye utilization ratios are improved; table salt, glauber salt or urea is not required; and unfixed dyes and the pollution discharge during the dyeing process are reduced.

Description

technical field [0001] The invention relates to a spray dyeing method using reactive dyes, and belongs to the technical field of textile dyeing. Background technique [0002] In the dyeing process of textiles, reactive dyes are currently one of the most important dyes for cellulose fiber dyeing, and pad dyeing is one of the important processes of reactive dyes. However, the current pad dyeing process of reactive dyes needs to consume a lot of water and chemicals, and the final discharge has brought great pressure to environmental protection. The current improvements to the dyeing process and dyes are all aimed at improving the efficiency of dye use, reducing pollution emissions, saving energy, and reducing the consumption of chemicals. [0003] The common process of continuous pad dyeing of traditional reactive dyes includes pad dyeing solution-drying-pad chemical solution-steaming-washing, cold rolling-stacking-washing, padding-baking-washing, padding-steaming-washing, pad...
