Embodiment Construction
[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0022] A kind of dyeing process of nylon fabric provided by the invention comprises the following steps:
[0023] (1) First, cold-stack the fabric, put the fabric into a flat cylinder, and put 50g / L alkali in the flat cylinder. The alkali is one or two kinds of sodium hydroxide and potassium hydroxide, and put 2g / L of penetrant, the cold pile time is 12h;
[0024] (2) Then carry out desizing treatment, pass steam into the flat cylinder to make the temperature in the flat cylinder reach 45°C; when the temperature in the flat cylinder reaches 45°C, keep warm, then add desizing and refining agent for the first desizing Sizing and refining treatment, the bath ratio of the first desizing and refining is 1:20, and the time is controlled at 4 hours; du...
