Low-bath-ratio high-temperature pulse type jet dyeing machine

Abstract

The invention provides a low-bath-ratio high-temperature pulse type jet dyeing machine. The jet dyeing machine mainly comprises a main cylinder, an auxiliary cylinder, a liquid adding pump, a cylinder cover assembly, an auxiliary cylinder liquid return pipe, a movement system, a dye flow dividing pipe, a liquid level meter, a pressure meter, a decompression valve, a main cylinder liquid return pipe, a main pump, an adding valve set, a steam trap assembly, a coiled pipe steam inlet, a star-shaped spraying pipe, a sprinkler spraying pipe, a filter screen, a heat exchanger, a partition board, a spraying pipe support, a center pipe, a transmission shaft and other parts. According to the pulse type high-temperature jet dyeing machine, spray dyeing is conducted on fabric from the upper direction and the lower direction by means of the star-shaped spraying pipe and the sprinkler spraying pipe, and dyeing uniformity can be effectively improved. A central control system controls the jet flow and pressure of dye liquid according to properties of the fabric and fabric winding thickness, and accordingly dyeing quality can be effectively controlled. The jet dyeing machine can obviously save auxiliaries and dye, reduces waste liquid discharge, and has extremely remarkable economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of dyeing machinery, in particular to a low-bath ratio high-temperature pulse-type jet dyeing machine. Background technique [0002] The textile industry is an important industry in my country's national economy. For a long time, the textile industry has made significant contributions to the development of the national economy, solving the problem of people's clothing, and exporting foreign exchange. status. The dyeing and finishing industry is the key to the deep processing, finishing and added value of textiles. It is the link between the processing of textile fibers, raw yarns, and embryonic cloths into final products that enter the consumer goods market. It plays an important role in promoting the common development of products. [0003] The liquor ratio is an important indicator in the dyeing process, and the size of the liquor ratio directly reflects the quality of the dyeing. The bath ratio refers to...

Problems solved by technology

On the contrary, if the bath ratio is large, the fuel concentration in the dye liquor is relatively low, and the dye concentration when the fabric fibers are dyed is also low, thus increasing the discharge of dye in the waste dye liquor
