Ecological nano dye and use method thereof

Abstract

The invention relates to an ecological nano dye for textile dye printing. The ecological nano dye consists of nano-level ecological paint color paste and liquidized ecological activated dye. The weight ratio of the nano-level ecological paint color paste to the liquidized ecological activated dye is 1:1-9. Before the ecological nano dye is used for dye printing, the textile is modified by cations; and after the dye printing, a wet rubbing fastness reinforcing agent is used to treat the textile. The textile dyed by the ecological nano dye has bright color and greatly improved color yield percentage, does not need high temperature soaping, does not discharge sewage during the dye printing, shortens the technical process, saves the energy source, reduces the production cost and improves the color fastness of the textile.

Description

technical field [0001] The invention relates to a dye used for dyeing and printing textiles and a use method thereof, an ecological nanometer dye and a use method thereof. Background technique [0002] Reactive dyes are used in the dyeing and printing of textiles. Due to their bright shade and low price, they have been widely promoted and used. However, their dyeing rate is low and their fixation rate is low. After printing and dyeing, a large number of floating colors are produced, which requires high-temperature soaping, resulting in A large amount of printing and dyeing sewage, at the same time, the printing and dyeing process is long and the investment in equipment is large. Pigment printing and dyeing solves the problem of sewage discharge and shortens the process. However, there are still many problems in paint printing and dyeing, such as dim color and poor color fastness. The nano-color and feel are poor. The current nano-paint color paste, that is, the particle size...

Problems solved by technology

[0002] Reactive dyes are used in the dyeing and printing of textiles. Due to their bright shade and low price, they have been widely promoted and used. However, their dyeing rate is low and their fixation rate is low. After printing and dyeing, a large number of floating colors are produced, which requires high-temperature soaping, resulting in A large amount of printing and dyeing sewage. At the same time, the printing and dyeing process is long and the investment in equipment is large. Pigment printing and dyeing solves the problem of sewage discharge and shortens the process flow. However, there are still many problems in paint printing and dyeing, such as dim color and poor color fastness. The nano-color and feel are poor. The nano-paint color paste currently introduced, that is, the particle size of the paint color paste reaches the nanometer level, so that the surface area of ​​the paint particles increases, the dark color and vividness of printing and dyeing are improved, and some problems in paint printing and dyeing are solved. Because paint particles have no affinity with fibers and are fixed on the surface of textiles by adhesives, even if the textiles are printed and dyed after cationic modification, there are still many problems in the brightness and color fastness of the textiles, which need to be further studied, especially After the paint is printed and dyed, the colored paint floats on the surface of the textile, but the core of the fiber is not dyed, and it is still the original white, which has a certain impact on the color of the textile.
