Problems solved by technology

However, because the process mixes the paint color paste and cationic modifier together and the concentration of cationic modifier is also high, although the dye bath includes a pH regulator and a surfactant, coagulation still occurs and the stability is poor , making dyeing difficult and unable to be industrialized

Abstract

The invention relates to a continuous pigment dyeing method for fabrics, in which the fabrics during travelling are subjected to the steeping of a composite dye solution in a steeping tank that is continuously supplemented with the composite dye solution, and then to the rolling of rollers, and the time the fabrics are subjected to the composite dye solution by the fabrics is 2.5-5 seconds. The composite dye solution comprises the components having the following concentrations: 10g/L-50g/L of a pigment paste, 1g/L-8g/L of a cation modifying agent, 3g/L-5g/L of a surfactant and 5g/L-20g/L of a cation bonding agent. The padding fabrics are continuously subjected to an infrared pre-drying apparatus for drying, a hot-air pre-drying tank for drying and a steam drying cylinder apparatus for drying. The inventive method has superior stability of the dyeing effect and is free from agglomeration.

Description

technical field [0001] The invention relates to a dyeing method, in particular to a continuous paint dyeing method for fabrics. Background technique [0002] With the development of dyeing and finishing technology, fabric dyeing includes not only dyeing, but also paint dyeing. Pigment dyeing mainly relies on the adhesive to form a layer of transparent film on the surface of the fiber at a certain temperature, so that the dispersed particles of the paint are wrapped and fastened on the surface of the fiber by the film to achieve the purpose of "dyeing". The use of dyes not only has strong adaptability, but also has a relatively complete chromatogram, which is especially suitable for the needs of small batches and multi-variety production, and the process is short, which greatly reduces pollution, saves energy, and reduces costs. However, due to the problems of poor dyeing depth, poor color fastness, hard hand feeling and sticking to rollers, continuous production is often im...
