Loose fiber cold pad-batch dyeing machine

Abstract

The invention relates to a loose fiber cold pad-batch dyeing machine which sequentially comprises an automatic bale plucker, a lapper, an immersion liquid tank with an automatic dosing system, an evenness calender, a coiling machine I, a cold pad-batch unit, an uncoiling machine I, a washing machine, a water calender, a coiling machine II, an uncoiling machine II, a drying machine and a packaging machine; in a bale storage box of the lapper, a centrifugal fan is arranged below a foot nail roller and communicated with the foot nail roller through a circulating air flue; a high-speed circulating spray pipe is mounted at the bottom of the immersion liquid tank; and a spray head on the high-speed circulating spray pipe is directly opposite to a fiber layer above the spray head. The machine provided by the invention has the advantages of high production efficiency, uniform dyeing, low water, electricity and energy consumption and low production cost.

Description

technical field [0001] The invention relates to a dyeing machine. Specifically, it is used for loose fiber cold pad-batch dyeing machine for cotton, viscose, modal, tencel and other cellulose fibers, and can also be used for refining, bleaching and softening of these loose fibers. Background technique [0002] At present, in the printing and dyeing industry, the bulk fiber dyeing machines used to dye cellulose fibers such as cotton, viscose, modal, and tencel are traditional dyeing machines. This traditional dyeing machine includes a cylinder body, and a fiber cage is arranged in the cylinder body or the fiber cage is separated from the cylinder body. A central nozzle is installed in the fiber cage, and the lower end of the nozzle is firmly connected with the cage bottom of the fiber cage. A heating coil is installed under the bottom of the cage, and one end of the heating coil protrudes out of the cylinder and communicates with the steam source. A motor and a wate...

AI Technical Summary

Problems solved by technology

The traditional process dyeing machine is to put the loose fiber to be dyed into the fiber cage, add water, dyeing materials, auxiliaries, etc., circulate in the tank under the action of the water pump, and then heat it to a certain temperature according to the process requirements, and then dye it. In the process, the power consumption is large, the energy consumption is high, and the color difference between the inner and outer layers and the unevenness of the cotton in the cylinder are prone to cause local color blooms

In addition, the dyeing rate is not high during the dip-dyeing process, and it is difficult to wash with water, causing great pressure on sewage discharge, and the large amount of sewage discharge results in high production costs.

Because the traditional dyeing machine is an intermittent dyeing method, it is prone to unstable factors such as cylinder difference, and the labor force is large and the production efficiency is low.
