Novel gas-fog dyeing machine

Abstract

The invention provides a novel gas-fog dyeing machine, which comprises a main cylinder body, a high pressure blower and a nozzle atomization system; an outlet at one end of the high pressure blower is communicated with a high pressure air inlet of the nozzle atomization system; two ends of the nozzle atomization system are a textile inlet and a textile outlet which are respectively communicated with the main cylinder body; a dye solution cutting nozzle, an energy converting nozzle and a cloth lifting roller are arranged in the nozzle atomization system; the dye solution cutting nozzle has an annular narrow slit shape; the axial section of the energy converting nozzle consists of three sections, namely a straight pipe section, a taper section and a gradual expansion section; and an inlet at the other end of the high pressure blower is communicated with an air filter screen in the main cylinder body. The special nozzle atomization system of the invention can well atomize the dye solution; and the dyeing machine adopts gas-fog flow for dyeing, cancels circulating dye solution dragging of textile and uses airflow to drag the textile to operate, thereby greatly reducing the bath ratio, saving the energy, reducing the pollution, and promoting the environmental protection.

Description

technical field [0001] The present invention relates to dyeing machines. Background technique [0002] At present, the dyeing equipment commonly used in my country's dyeing industry is mainly liquid flow dyeing machine. Its main principle is to spray the mixture of liquid dye auxiliaries and water on the fabric through the nozzle, so that the fabric can obtain the power of circular movement while being dyed. It must provide enough water for the circulating pump to drive the fabric, which requires a very high bath ratio, and at the same time brings defects such as high energy consumption, large sewage discharge, low cloth speed and poor economic benefits of the enterprise. Moreover, since the movement of the fabric mainly depends on the friction between the dye liquor and the fabric to transfer the kinetic energy to the fabric, the density of the liquid flow is relatively high, and in the process of continuous friction with the fabric, it will have a great impact on the fabr...

It must provide enough water for the circulating pump to drive the fabric, which requires a very high liquor ratio, and at the same time brings defects such as high energy consumption, large sewage discharge, low cloth speed and poor economic benefits of the enterprise.

Moreover, since the movement of the fabric mainly depends on the friction between the dye liquor and the fabric to transfer the kinetic energy to the fabric, the density of the liquid flow is relatively high, and in the process of continuous friction with the fabric, it will have a great impact on the fabric, which will easily cause fiber wear. , affect the appearance of the fabric, and even cause the displacement of the warp and destroy the structure of the fabric
