Abstract

The invention provides a process for printing and dyeing a wool fabric. The process comprises the following steps of: a preparation procedure, washing, an ionic liquid pretreatment process, a printing and dyeing process, an aging process, an after treatment process, and obtaining of the finished product. The process for printing and dyeing a wool fabric provided by the present invention effectively increases the dye-uptake of the wool fabric by means of the pretreatment using the ionic liquid to the wool fabric; secondly, a reactive dye is used in the printing and dyeing process herein, and an acid-releasing agent is added to effectively regulate the pH value in the dyeing process such that the dye is uniformly attached on the fabric. The process for printing and dyeing the wool fabric provided by the present invention is safe and non-toxic, and further is capable of improving the color fastness, reducing the dyeing bath ratio and reducing the dosages of the dye and printing and dyeing auxiliaries. Furthermore, the process is simple, obvious in beneficial effects, and suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of wool fabric dyeing, and more particularly to a wool fabric dyeing process. Background technique [0002] With the growth of population and the improvement of quality of life, pure cotton, pure wool, silk, and chemical fiber products can no longer meet people's requirements for fabrics that are not only beautiful but also warm and smooth. Cotton fabrics have excellent hand feeling and wearability, while wool fabrics have the characteristics of softness, moisture absorption, and warmth retention. Combining the advantages of the two, wool fabrics, a new type of clothing fabric, have been produced. [0003] Wool fabrics are generally divided into two types: (1) Woven fabrics, also known as woven fabrics, are fabrics formed by interweaving warp yarns and weft yarns perpendicularly to each other. There are three basic weaves: plain weave, twill weave and satin weave. Different woven fabrics are also composed of these t...
