Integrated horizontal waterless dyeing and finishing kettle and dyeing and finishing method adopting same

Abstract

The invention provides an integrated horizontal waterless dyeing and finishing kettle. The waterless dyeing and finishing kettle comprises a kettle body, an insulating jacket, a spiral hot oil guide ring, an end cover, a kettle bottom head, a CO2 discharge pipe, a conduction oil feed pipe, a wash liquid feed pipe, a conduction oil discharge pipe, a reeling shaft inner barrel, guide wheels, an end seal pipe and a CO2 feed pipe, wherein the insulating jacket is arranged outside the kettle body; the spiral hot oil guide ring is arranged in the jacket; the end cover is hinged at the end head of the kettle body; the kettle bottom head is installed at the end tail of the kettle body; the CO2 discharge pipe is installed at the end head of the kettle body and is close to one side of the end cover; the conduction oil feed pipe is installed at the end tail of an insulating outer barrel; the wash liquid feed pipe is installed at the bottom of the kettle body; the conduction oil discharge pipe is installed at the end head of the insulating outer barrel; the reeling shaft inner barrel is installed in the center of the interior of the kettle body and horizontally runs through the interior of the kettle body; the guide wheels are installed at the end head and end tail of the reeling shaft inner barrel; the end seal pipe is connected at the end tail of the reeling shaft inner barrel in a sleeving manner; and the CO2 feed pipe is connected in the end seal pipe in a sleeving manner. The invention also provides a waterless dyeing and finishing method. The method comprises the steps of charging, deoiling, dyeing, washing and discharging. The integrated horizontal waterless dyeing and finishing kettle takes the supercritical CO2 technology as the core and integrates the functions of deoiling, dyeing and washing.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing and finishing, and in particular relates to an integrated horizontal anhydrous dyeing and finishing kettle and a dyeing and finishing method thereof. Background technique [0002] Dyeing and finishing is an industry with high pollution and high water consumption, and water is a very precious resource. In the whole dyeing and finishing production process, except for singeing and mechanical finishing, it is all carried out in water, that is, wet processing process. According to estimates, the weight ratio of printed and dyed fabrics to discharged wastewater is as high as 1:150. The national printing and dyeing wastewater discharge is estimated to be 1 billion tons a year. The cost of wastewater treatment is expensive, accounting for 35% of the total industrial wastewater discharge. Wastewater is added with various dyes, auxiliaries and precipitants, so it is difficult to recover effectively, ...
