AI Technical Summary
Technical Problem
In existing polyester fiber dyeing equipment, excessive dye liquor leads to high production costs, unstable fabric movement, easy friction damage, and inability to adapt to changes in fabric thickness, thus affecting the dyeing quality.
Method used
The design incorporates an inner tube and a drain hole, and the amount of dye liquor and the thickness of the liquid film can be adjusted by an adjustment mechanism. Combined with pressing and guide rollers, it ensures stable movement of the fabric and uses a reflux mechanism to optimize the recycling of dye liquor.
Benefits of technology
It enables stable fabric movement, reduces dye usage, improves printing and dyeing quality and efficiency, adapts to different fabric thicknesses, reduces friction damage, and saves energy.
