Problems solved by technology

However, there are many technical problems in the one-bath and one-step dyeing of polyester wool knitted fabrics: (1) Due to the difference between polyester fiber and wool fiber, the dyeing conditions are different; the dyeing of polyester fiber requires high temperature and pressure, and the dyeing temperature in the bath can usually be as high as 135°C, such a temperature is destructive to the physical strength of wool; however, if the dyeing temperature is lowered, the choice of ordinary disperse dyes will cause problems in the coloring of polyester, such as light coloring, and the dyes will not be efficient. (2) The staining of wool fibers by disperse dyes is inevitable, which is the main reason for the poor color fastness of the final polyester wool fabrics; (3) The color fastness of polyester wool knitted fabrics The cleaning process has always been a thorny problem; if the cleaning force is increased, the temperature is increased, the alkalinity is enhanced, and chemicals such as hydrosulfite and thiourea dioxide are added, then the excellent washing fastness is usually at the expense of the loss of wool strength

Abstract

The invention belongs to the field of textile printing and dyeing, and relates to a dyeing method for a fabric, particularly to a dyeing method for a polyester wool knitting fabric. According to the dyeing method of the present invention, the dyeing process is performed by adopting two dyes and two thermal insulation stages. With the present invention, problems of poor washing fastness and poor physical strength of the polyester wool knitting fabric dyed by using a one-bath one-step method in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and relates to a fabric dyeing method, in particular to a polyester wool knitted fabric dyeing method. Background technique [0002] As a classic multi-component fabric, polyester wool knitted fabric has unique wearing performance. It is compatible with the excellent strength performance, wrinkle resistance and excellent dimensional stability of polyester knitted fabric, and the wearing comfort and comfort of wool knitted fabric. Hygroscopicity, breathability. Therefore, the polyester-wool knitted fabric is a high-grade knitted fabric, which is favored in domestic and foreign markets, and its market prospect is broad. [0003] Due to the large difference in physical properties and chemical properties between polyester fiber and wool fiber, it is very difficult to dye polyester wool knitted fabrics in the same bath. Nowadays, printing and dyeing enterprises usually use yarn-dyed weavin...
