Abstract

A supercritical fluid dyeing and finishing system has a fabric warp beam dyeing kettle. A fabric warp beam dyeing and finishing unit is arranged in the fabric warp beam dyeing kettle. An external magnetic transmission device II is arranged outside the fabric warp beam dyeing kettle. The fabric warp beam dyeing and finishing unit includes a porous pipe I and a porous pipe II. The porous pipe I and the porous pipe II are connected with an inlet of the fabric warp beam dyeing and finishing unit through a bearing I and a bearing II. A fluid ejector is connected with the inlet of the fabric warp beam dyeing and finishing unit and disposed in the vicinity of the porous pipe I and the porous pipe II.
