Circulation gradual change formula weaving dyeing apparatus

Technical Field

The invention relates to the technical field of textile dyeing, in particular to a circular gradual change type textile dyeing device.

Background

With the continuous development and improvement of the textile knowledge system and the discipline system, particularly after the production of non-woven textile materials, three-dimensional compound knitting and other technologies, the textile is not only the traditional hand-made spinning and weaving, but also the textile for clothing, industry and decoration produced by the non-woven fabric technology, the modern three-dimensional knitting technology, the modern electrostatic nano-net forming technology and the like. Dyeing, i.e. coloring, also known as coloring, refers to the coloring of a substance by chemically or otherwise affecting the substance itself. Under the condition that the technology allows, the object can present various colors required by people through dyeing, and people live in different colors. Textile materials are treated with a dye bath to chemically or physico-chemically bind the dye to the fibers or to produce insoluble colored materials on the fibers. The gradual change color is the color of an object which is gradually changed from light to dark, or from dark to light, or from one color to another color, and is full of the mysterious romantic breath which changes infinitely. Fading is a popular color in the textile dyeing industry in recent years.
