Continuous cold-rolling and steaming dyeing process and equipment of active dyestuff

Abstract

The invention relates to a continuous cold-rolling and steaming dyeing process and equipment of an active dyestuff. The continuous cold-rolling and steaming dyeing process comprises the following steps: 1, padding the dyestuff; 2, steaming and fixing color; 3, soaping; 4, carrying out acid washing; 5, softening and fixing color; 6, squeezing and drying. In the step of padding the dyestuff, the active dyestuff and a color fixing auxiliary agent are prepared separately; in an active dyestuff preparation process, a penetration auxiliary agent is added; the prepared active dyestuff and the color fixing auxiliary agent are mixed online and then are added into a dyeing vat; the temperature of a dyeing solution in the dyeing vat is controlled to be 0 to 10 DEG C and the time for padding the dyestuff is 4s to 8s; a small-capacity dyeing vat is adopted as the dyeing vat and the updating period of the dyeing solution is 8min to 15min; a sewing body, yarns or textiles pass through a plurality of groups of rollers in the dyeing vat for a plurality of times of squeezing and pad dyeing. The continuous cold-rolling and steaming dyeing process and equipment of the active dyestuff have the beneficial effects that continuous type dyeing is carried out; the production efficiency is greatly improved and the labor intensity is alleviated; the consumption of energy sources and resources including water, power, steam and the like is also greatly reduced and the environment pollution is further reduced.

AI Technical Summary

Benefits of technology

This technology allows for better continuation during dyeings without requiring more time or effort than traditional methods like immersions or spray techniques. It can save both money on fuel usage (making it easier) and reduce emissions from power plants that use fossil fuels such as coal).

Problems solved by technology

In current methods of producing cotton loft thread through dipped dyeings, there exist issues such as slow down processing speed due to heavy load caused by weld seams during cleanup work (such as removing impurities) that can cause streaks overlaid onto other threads when they come into contact again. Additionally, existing methods require multiple steps including rinses before dying, which increases costs associated with these operations.
