Problems solved by technology

We can clearly see that the whole system starts up when dyeing a batch of fabrics, and stops when the batch of fabrics is dyed. Dyeing in the dyeing kettle will inevitably lead to many pipelines, high resistance, and inconvenient cleaning; therefore, the dyeing operation cost is high, the efficiency is low, and the minimum requirements for industrialization cannot be met. Therefore, these current patents and reports of various materials are still in the state of laboratory stage

Abstract

The present invention relates to a supercritical carbon dioxide dyeing continuous production equipment and its continuous dyeing method for dyeing fabrics. Said equipment includes a dyeing circulation system device which is connected after preheater by means of pipeline, can be cut off by valve and can be independently operated and a dye and carbon dioxide recovery system deice which is placed after the above-mentioned dyeing circulation system device, can be cut off by valve and can be independently operated. Said dye and carbon dioxide recovery system also is communicated with carbon dioxide storage tank by means of pipeline. Besides, said invention also provides the concrete steps of said continuous dyeing method by utilizing the above-mentioned equipment.

Description

technical field [0001] The invention relates to a device in the dyeing and finishing industry, in particular to a supercritical carbon dioxide dyeing device. Background technique [0002] As we all know, the dyeing and finishing industry in the general civil industry is the largest source of pollution. All countries in the world are conducting pollution-free research from equipment to technology. Among these research projects, supercritical carbon dioxide dyeing is more advanced. It has everything from equipment to technology. The new route completely eliminates the traditional production equipment and process methods, so that the dyeing can reach the state of pollution-free production. At the same time, supercritical carbon dioxide dyeing is fast, reaching 5-10 times of the traditional process, and has good leveling and penetration, and can achieve a dyeing rate of more than 98%. The dye and carbon dioxide can be reused, and no dispersant is needed. , leveling agent, buffe...
