Abstract

The invention discloses an application of a dye in dyeing of nylon cotton fabrics. A preparation method of the dye comprises the following steps of putting together and mixing components of the dye combination; the dye combination contains 50%-90% of a component A and 10%-50% of a component B, wherein the percentage is the mass percentage of the component mass accounting for the total mass of the dye combination; the component A is one or more of compounds represented by the formula one, and the component B is one or more of compounds represented by the formula two. The dye can achieve dyeing of the nylon cotton fabrics through a one-bath method, thereby greatly saving the dyeing time; at the same time, the dye provided by the invention can obtain better color fastness, all the fastness can reach or be superior to effects that a two-bath method can achieve, and moreover, homochromatism of the one-bath method is easier to implement compared with the two-bath method; and the dye provided by the invention has good deep dyeing property on the nylon cotton mixed fabrics.

Description

technical field [0001] The invention relates to the application of a dye in the dyeing of nylon and cotton fabrics. Background technique [0002] In recent years, with the development of fashion and people's continuous demand for high-quality fabrics, nylon-cotton interwoven or nylon-cotton elastic interwoven fabrics are becoming more and more popular, especially in the seamless underwear market and the clothing fabric market such as windbreakers and jackets. widely used. Traditional nylon and cotton fabrics are generally dyed by the two-bath method, which has the disadvantages of long production cycle, excessive use of auxiliaries, large energy waste, and large sewage discharge. Many dyeing factories are also exploring the one-bath dyeing of nylon and cotton, but limited to the current situation of existing dye products, they have not been able to obtain ideal dyeing effects, such as insufficient dyeing depth and poor homochromaticity of nylon and cotton.
