Anti-felting Dyeing and Finishing Technology of Wool Fabric

Abstract

The invention discloses an anti-felting dyeing and finishing technology of a wool fabric. A systemic and complete flow from dying pretreatment, low temperature plasma treatment, a supercritical carbon dioxide disperse dyeing treatment technology and an acidic dye two-stage dyeing treatment technology to an after-treatment dyeing and finishing technology cooperates with a disperse dye specially produced for the special properties of the wool fabric and an acidic mixed dye composition, and fabric treatment before dyeing of the pretreated wool fabric is carried out by using low temperature plasma, so the anti-felting performance of the wool fabric is improved, the dyeing adhesion is enhanced, and the color fixation effect is increased. The anti-felting dyeing and finishing technology of the wool fabric has the advantages of simplicity in operation, brilliant dyed color of the fabric, no color fading, effective improvement of the wet fastness, good dyeing effect, uniform color, difficulty in color fading, high industrialization degree, good ecologic and environmentally-friendly property, energy saving and emission reduction, and environmental protection and low carbon.

Description

technical field [0001] The invention relates to a fabric dyeing and finishing process, in particular to a wool fabric anti-felting dyeing and finishing process. Background technique [0002] Wool fabric is a kind of natural fiber fabric. Wool fiber has excellent performance, excellent curl and elasticity, warm and comfortable, and is loved by consumers. However, wool fabric has insufficient bright colors, poor wet fastness and felting shrinkage. The biggest problem, this is because the wool surface has a tight scale layer, and the outermost layer of wool scales contains a very thin hydrophobic layer, which affects the wettability of the wool surface and hinders the adsorption and diffusion of dyes, thus affecting the dye. In addition, its fiber characteristics are easy to feel and shrink, which also brings difficulties to uniform dyeing. In addition, some mordant dyes have environmental pollution when dyeing wool fabrics, and cannot adapt to the development of the environmen...

[0002] Wool fabric is a kind of natural fiber fabric. Wool fiber has excellent performance, excellent curl and elasticity, warm and comfortable, and is loved by consumers. However, wool fabric has insufficient bright colors, poor wet fastness and felting shrinkage. The biggest problem, this is because the wool surface has a tight scale layer, and the outermost layer of wool scales contains a very thin hydrophobic layer, which affects the wettability of the wool surface and hinders the adsorption and diffusion of dyes, thus affecting the dye. In addition, its fiber characteristics are easy to feel and shrink, which also brings difficulties to uniform dyeing. In addition, some mordant dyes have environmental pollution when dyeing wool fabrics, and cannot adapt to the development of the environment of energy saving and emission reduction. Trend, how to improve wool dyeing performance, increase wet fastness, reduce environmental pollution, a kind of anti-felting dyeing and finishing process suitable for wool fabrics that can solve the above problems is worth studying
