Dyeing tube structure of conveyor driven fabric dyeing machine

Abstract

A conveyor driven fabric dyeing machine includes a dyeing tube for improving fabric dyeing effect. The dyeing tube is arranged rearward of or below a nozzle and has an entrance opening and an exit opening and an intermediate section located between and set lower than the entrance opening and the exit opening so as to form height differences at front and rear end parts of the dyeing tube that allows dye liquid to fill up and remain in the dyeing tube. During a course of fabric moving through the dyeing tube, the fabric is allowed to stay and soak in the dye liquid within the dyeing tube to provide an extended period of time of interaction between the fabric and the dye liquid for penetration so as to enhance the result of dyeing.

I claim: 
     
         1 . A conveyor driven fabric dyeing machine comprising a dyeing tube having a structure that allows for improving a dyeing result of fabric, wherein the dyeing tube is arranged and mounted rearward of or below a nozzle, the dyeing tube comprising a fabric and liquid entrance opening and a fabric and liquid exit opening, the dyeing tube having an intermediate section that is set lower than the fabric and liquid entrance opening and the fabric and liquid exit opening so that the dyeing tube is configured to include height differences that allows dye liquid to fill up an interior space of the dyeing tube and remain in the dyeing tube, wherein during a course of fabric moving through the dyeing tube, the fabric is allowed to stay and soak in the dye liquid within the dyeing tube to provide a sufficient period of time of interaction between the fabric and the dye liquid remaining in the dyeing tube and thus an extended period of time of penetration is realized to enhance the result of dyeing, wherein the dyeing tube has a configuration that provides the height differences at front and rear ends thereof.
