One bath super dark dyeing technology of polyester-cotton fabric disperse and reactive dyes

Abstract

The invention provides a super-dark dyeing technology by dispersing the polyester-cotton fabrics and one bath of the reactive dye, which belongs to a dyeing technology of the fabrics. The technology comprises the following steps: selecting the WW series disperse dyes and C series reactive dyes to soak the pure cotton fabrics into the dyeing solution for one time, then rolling with a squeezer for one time, then pre-baking and baking the cloth, then steaming in a steaming chamber, then washing with water after the steaming, then washing with soap after the water washing, then washing the cloth with water again and drying to finish the dyeing process. The disperse dyes and reactive dyes selected by the dyeing technology has high color yield and good color fastness and the loose color on the fabrics can be completely washed during the soap washing process, therefore, the loose color can not dye the surface of the fabrics, which basically solves the color transfer fastness and wet grinding fastness of the super-dark color. The design of the baking temperature is reasonable, which improves the color yield of the disperse dyes and the color fastness of the dye; the adopted one-bath dyeing process is simple in process flow and low in production cost and the amount of the sewage is few and the dyeing quality is stable.

Description

technical field

[0001] The invention relates to a fabric dyeing process, in particular to a very dark dyeing process of polyester-cotton blended fabric. Background technique

[0002] Polyester fiber has the characteristics of good strength, body, not easy to deform, and poor hygroscopicity. Cotton fiber has the characteristics of softness, heat preservation, and excellent hygroscopicity. Polyester-cotton blended fabrics combine the advantages of the above two fibers, and the garments made of them are not deformed, have a solid body, are soft, moisture-absorbing, wear-resistant, and comfortable to wear, and are very suitable for use as tooling fabrics. However, due to the difference in chemical structure and performance between the two, it is more difficult to achieve the same color when dyeing, especially the dyeing of extra dark colors is faced with two difficulties: dyeing cost and dyeing fastness. At present, the extra dark color of polyester-cotton fabrics adopts the tw...
