Pad-steam dyeing equipment and method thereof

Abstract

The invention relates to pad-steam dyeing equipment. The pad-steam dyeing equipment comprises a cloth sending device, a dye padding device, a pad-steam dyeing device and a finished product collection device which are sequentially arranged along the sending direction of the cloth. The pad-steam dyeing device consists of a rack, a power assembly, a large heating wheel, a high-temperature-resistant conveyor belt and a supporting guide wheel group. The power assembly is arranged on the rack and connected with the large heating wheel and used for driving the large heating wheel to rotate. The supporting guide wheel group comprises a plurality of supporting guide wheels, the high-temperature-resistant conveyor belt is respectively sheathed on each supporting guide wheel, and sheathed outside the large heating wheel, the large heating wheel and the high-temperature-resistant conveyor belt are used for clamping the cloth and performing pad-steam dyeing operation to the cloth. Due to the cladding of the high-temperature-resistant conveyor belt, the dye is difficultly escaped into the atmosphere after sublimation, thus being beneficial to dyeing. The pad-steam dyeing equipment is used for pad-steam dying the cloth containing dyeing solution, the dye utilization rate is high, the dye yield is deep, the color firmness is higher, the flooding on the surface of the cloth is less, and the discharge of waste water is less.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to steam pad dyeing equipment and a method thereof. Background technique [0002] As we all know, disperse dyes will be sublimated into gas under certain temperature conditions, and a considerable part of the dye molecules in the traditional thermosol sublimation dyeing process are not absorbed in the fabric fibers after sublimation, but volatilize into the atmosphere Therefore, the traditional dyeing equipment and dyeing methods have the problems of low dye utilization rate, shallow color yield, poor color fastness, and more floating colors on the surface of the dyed fabric. In addition, more floating colors on the surface of the fabric will cause The follow-up must go through multiple washing processes, resulting in environmental pollution. Contents of the invention [0003] Based on this, it is necessary to provide a steam-pad dyeing equipment and method w...
