AI Technical Summary

Technical Problem

Existing dyeing equipment for napped fabrics suffers from problems such as uneven dyeing, insufficient dyeing due to nap entanglement, and uneven impact of the stirring mechanism on the fabric, which affect the fabric quality.

Method used

The design incorporates a combination of an adjustment frame, a wiping frame, and a stirring mechanism. The position of the guide roller and the movement of the fluff brush are controlled by a servo motor. Combined with the stirring mechanism's agitation at both ends inside the dyeing chamber, this ensures that the fabric remains at a constant length in the dye and improves dye penetration.

Benefits of technology

It achieves consistent and uniform fabric dyeing depth, improves the dyeing effect at the root of the pile, avoids fabric wrinkles and uneven impact, and improves the quality of finished products.
