Method for preparing blended knitted fabric dyeing composition

Abstract

The invention discloses a method for preparing a blended knitted fabric dyeing composition. The blended knitted fabric dyeing composition is composed of a dye A and a dye B, wherein the dye A is the disperse dye composition for first dyeing treatment and the dye B is the active dye composition for secondary dyeing treatment. The invention provides the preparation method of the dye A and the dye B. The preparation method is simple and takes short time, and the raw material is cheap and easy to obtain; the prepared dye composition has stable chemical property, the adhesive force of dyeing is increased effectively, and the color fixation effect is enhanced; the fabric has bright dyeing color, and does not fade; the dyeing composition has an excellent dyeing effect on the blended knitted fabric, dyeing is uniform and the fabric is not prone to fade.

Description

technical field

[0001] The invention relates to a fabric dyeing agent, in particular to a preparation method of a blended knitted fabric dyeing composition. Background technique

[0002] At present, the types of fibers on the market are becoming more and more abundant. Knitted fabrics are formed by bending yarns into coils and connecting them in series according to certain rules. , It has played a huge role in meeting the domestic market demand and earning foreign exchange through export.

[0003] There are many kinds of knitted fabrics, which can be divided into cotton knitted fabrics, wool knitted fabrics, silk knitted fabrics, chemical fiber knitted fabrics and blended knitted fabrics according to raw materials. Among them, blended knitted fabrics are made by blending two or more different fibers. Yes, in the process of dyeing and finishing, problems such as uneven dyeing, difficult color fixation, and easy fading are prone to occur. At present, there is no dyeing compos...
