An extrusion vortex dyeing machine for yarn processing

By combining the dual dyeing unit and the extrusion unit, the problem of color saturation and uniformity in spinning dyeing equipment when dealing with darker and more concentrated dyes is solved, achieving a highly efficient dyeing effect, especially for uniform dyeing of colors such as jet black and navy blue.

AI Technical Summary

Technical Problem

Existing spinning and dyeing equipment struggles to guarantee color saturation and uniformity when dealing with darker and more concentrated dyes, and a single dyeing cycle cannot effectively solve the problem of uneven dyeing.

Method used

The design employs a combination of dual dyeing units and extrusion units. The first and second dyeing units dye the yarn twice, and during the second dyeing, the extrusion and second dyeing units are staggered and intersected, causing the yarn to reciprocate in a wavy state. Combined with the design of turbine fans and extrusion rollers, multiple dye contacts and extrusions are achieved.

Benefits of technology

It improves the color saturation and dyeing uniformity of the yarn, ensures the dyeing effect when faced with darker and more concentrated dyes, avoids uneven dyeing, and improves the dyeing quality.

Abstract

This invention relates to the field of textile dyeing and processing technology, and particularly to an extrusion-type vortex dyeing machine for yarn processing. It includes a first housing, with a second housing connected to one side of the first housing. A first dyeing unit for primary dyeing of the spun yarn is installed within the first housing. Several sets of extrusion units are arranged at equal intervals along a horizontal direction within the second housing. A second dyeing unit is located directly below the junction of adjacent sets of extrusion units. This invention allows the pigment in the dye to be repeatedly dehydrated and adhered to the yarn fibers. Furthermore, when encountering uneven dyeing problems, it utilizes multiple contacts with the dye and extrusion to ensure uniform dyeing on the yarn surface. This not only ensures the color saturation of the yarn even when dealing with deep and concentrated dyeing requirements such as jet black and navy blue, but also avoids uneven dyeing, thereby improving the dyeing effect.
