Single-sided dyeing liquid feeding equipment for reactive dyes of pure cotton heavy fabric and method

Abstract

The invention discloses single-sided dyeing liquid feeding equipment for reactive dyes of pure cotton heavy fabric. The equipment comprises a dyeing mechanism, a drying mechanism and a color fixationmechanism which are arranged sequentially, wherein the dyeing mechanism comprises a dye liquid tank as well as a rubber squeezing roll, a single-sided liquid feeding coloring roll and a rotating rubber roller which are arranged above the dye liquid tank, a dye liquid conveying roll is arranged in the dye liquid tank and connected with the single-sided liquid feeding coloring roll through a conveying belt, and two sides of the single-sided liquid feeding coloring roll are tangent with the rubber squeezing roll and the rotating rubber roll respectively. The invention also discloses a method fordyeing fabric by using the single-sided dyeing liquid feeding equipment for the reactive dyes of the pure cotton heavy fabric. By use of the device and the method, the defects that more dyes are wasted due to double-sided dyeing of the heavy cotton fabric, water consumption for printing and dyeing washing is large, and the quantity of vapor consumed during drying is large are overcome.

Description

technical field [0001] The invention relates to a liquid supply technology for one-side dyeing, in particular to a liquid supply equipment and method for one-side dyeing of pure cotton heavy fabric reactive dyes. Background technique [0002] Reactive dye dyed cotton fabrics in the prior art usually adopt methods such as exhaust dyeing and pad dyeing. When dyeing, all the front and back sides of the fabric are dyed to achieve the purpose of level dyeing on both sides and inside the fiber. However, this method will cause the user to have dyes or additives on the side that contacts the skin when wearing it, causing color fading when wearing and causing dyeing problems for the skin and inner clothing, and even due to long-term exposure to potential dyes contained in the dye. Harmful substances are harmful to the human body, such as the risk of cancer caused by carcinogens that may be contained in dyes after decomposition.
