AI Technical Summary

Technical Problem

The uneven dipping and dyeing problem caused by fiber composition differences in traditional open dyeing tanks requires additional mixing equipment to increase costs and energy consumption.

Method used

The combination of front multi-side belt co-feeding type immersion dyeing assembly, side-band driven liquid mixing assembly, multi-tube liquid spray counter-dyeing assembly, double-roll elastic pressing structure and multi-roll dyeing assembly is adopted to achieve uniform penetration and efficient dyeing of dyeing liquid by mechanically constraining fabric movement and precise temperature control.

Benefits of technology

The excellent dyeing uniformity of blended fabrics is achieved, equipment investment and operation energy consumption is reduced, high-cost independent mixing equipment is avoided, and impregnation and dyeing problems are reduced.

Abstract

The invention relates to the technical field of blended fabric dyeing and finishing, in particular to a blended fabric dyeing and finishing device and a dyeing and finishing method.The blended fabric dyeing and finishing device comprises a dye vat with a bottom heating assembly, a front polygonal belt type co-conveying dip dyeing assembly is installed on one side in the dye vat, and an inner supporting frame is fixed to the other side in the dye vat; a multi-pipe liquid spraying type redyeing assembly is installed at the top end of the dye vat between the inner supporting frame and the front multilateral belt type co-conveying dip dyeing assembly, and a multi-roller type pad dyeing assembly is installed on the upper portion of the interior of the inner supporting frame. According to the invention, the problem of dip dyeing fluctuation caused by free movement difference and non-uniform fluid of the blended fabric in the traditional open dye vat is solved, the dyeing uniformity is realized, and through ingenious structural integration, independent stirring equipment which is high in energy consumption, high in cost, easy to damage the fabric and complex to maintain and accessory systems of the independent stirring equipment are completely omitted.
