Description

Fabric Dyeing Machine {FABRIC DYEING MACHINE}

The present invention relates to a fabric dyeing machine, and more particularly to a fabric dyeing machine capable of dyeing a large amount of fabric in a small volume and occupies a small installation space.

Conventionally, a liquid circulation type textile dyeing machine is known which circulates and dyes endless fabrics which are connected to the ends of elongated fabrics by spraying salt solution under high pressure or atmospheric pressure. A salt spray nozzle is provided on the side, and the upper portion of the fabric conveying pipe for conveying the fabric by spraying the salt solution and the fabric conveyed through the fabric conveying pipe stay in the cylindrical form so that the dye is concentrated by the salt solution. It consists of a lower fabric retention tube having a diameter larger than the diameter of the fabric transfer pipe, and the upstream end of the fabric transport pipe and the downstream end of the fabric transport pipe are connected to a header having a guide roll installed therein. The downstream end of the fabric conveying pipe is directly connected to the upstream end of the fabric retaining pipe so that the endless type of fabric connecting the ends is fabricated. Upstream of the conveying pipe is transferred to the fabric conveying pipe by the salt solution sprayed from the salt spray nozzle to reach the fabric retaining pipe, and after the concentrated dyeing is carried out in the fabric retaining pipe, the fabric conveying pipe again through the guide roll in the header. Guided to the upstream side of the can be dyed while continuous circulation.

However, this type of fluid circulation type fabric dyeing machine is subjected to a large tension on the fabric by the strong liquid flow of the salt solution sprayed through the injection nozzle when the fabric is conveyed through the fabric conveying pipe and generates fine wrinkles on the fabric The fabric may be damaged, and the wrinkles of the fabric that circulate as a whole may be less likely to change the wrinkles.

In particular, this type of fluid circulation type dyeing machine requires relatively large volume dyeing processing spaces for the continuous transport of the fabrics and the fabric conveying pipes arranged in a long horizontal direction for continuous dyeing of the long fabrics. The installation space of the dyeing machine also requires a relatively large space.

In the present invention, it is conceived in view of such a conventional situation. A vertical textile section is divided into vertical cylinders and constituted by the first and second dye tanks, and a fabric extending from the header installed on the upper side of each dye tank. By extending the pipe to the lower inner side of the dyeing tank, the fabric can form a dyeing processing space where the fabric can be sufficiently dyed while passing through the fabric feed pipe and each dyeing tank. Provide a textile dyeing machine to take up less.

To this end, the present invention provides a fabric dyeing machine having a hemispherical bottom portion and an upper cover and consisting of a cylindrical dyed cylinder installed upright by a support. According to the present invention, the partition wall is installed inside the dyeing cylinder and partitioned into the first and second dye baths, and the tubular header communicating with each other in each dye bath is installed, and the guide roll for guiding the fabric therein is installed. The lower side of the header is characterized in that it is disposed so that the upwardly bent portion of the lower end of the first and the second dye bath to the upper side of the fabric conveying pipes with the salt spray nozzles installed on the upper side downward.

Referring to the present invention in more detail based on the accompanying drawings as follows.
