A convection dyeing vat for fabric

Abstract

The invention provides a counter flow type fabric dye vat. The counter flow type fabric dye vat comprises a dye vat body, wherein flexible grooves are annularly distributed on the peripheral wall of the dye vat body, wherein the two ends of the flexible flow guide grooves are respectively connected with the top edge and the bottom edge of the dye vat body; the top edge of the dye vat body is provided with jet nozzles matched with each flexible flow guide grooves; liquids jetted by the jet nozzles flow through the flexible flow guide grooves; the center of the bottom of the dye vat body is provided with an upflow opening from which the liquids are jetted out; liquid inlets of the jet nozzles and the upflow opening are formed in the dye vat body. The jet nozzles are used for jetting liquids to the flexible flow guide grooves, so that the flexible flow guide grooves are internally filled with liquids flowing downward; the liquids flowing downwards are in contact with fabrics required to be dyed, and convey the fabrics to move downwards; after the fabrics roll to the bottom of the dye vat body, the liquids jetted out of the upflow opening are brought to the top of the dye vat body, and the fluidity in the dye vat body is increased.

Description

[0001] Technical field [0002] The invention relates to the field of textile dyeing and finishing equipment, in particular, a convection dyeing vat for fabrics. Background technique [0003] Dyeing refers to the process in which the dye is dyed from the dye solution to the fiber and forms a uniform, firm and bright color on the fiber. The chemical composition of various fibers is different, and the applicable dyes are also different. Cotton fabrics are mainly dyed with reactive dyes. Polyester fabrics are mainly dyed with dispersed miscellaneous materials. The commonly used dyeing methods include high temperature method, carrier method and hot melting method. [0004] The dyeing of fabrics is generally carried out in the dyeing vat, and the fabric is generally filled into the dyeing vat. The dyeing vat maintains a certain temperature and pressure and an appropriate dyeing ratio to achieve the best dyeing environment. However, the capacity of the general dyeing vat is limite...

Problems solved by technology

[0004] The dyeing of fabrics is generally carried out in the dyeing vat, and the fabric is generally filled into the dyeing vat. The dyeing vat maintains a certain temperature and pressure and an appropriate dyeing ratio to achieve the best dyeing environment. However, the capacity of the general dyeing vat is limited. Considering the economy of dyeing, the fabric And the amount of processing will fill the entire dye vat, because the fabric itself has a blocking effect on the fluidity of the liquid, so the position of the fabric in the dye vat generally does not change, and the fluidity of the dye solution around the fabric is also poor
