Method for improving color fastness of waterproof polyester-cotton fabric

Abstract

The invention discloses a method for improving the color fastness of a waterproof polyester-cotton fabric. The method comprises the specific process as follows: firstly, carrying out water boiling onthe waterproof polyester-cotton fabric in a dyeing vat containing a detergent 6501; then carrying out water boiling and washing in pure water; then after immediately carrying out cold water washing, adding a chlorine-resisting color fixing agent F-323 and enabling the chlorine-resisting color fixing agent F-323 to impregnate the waterproof polyester-cotton fabric; then taking out the waterproof polyester-cotton fabric from the dyeing vat and drying and roasting in sequence; finally, enabling the color fastness of the waterproof polyester-cotton fabric to be remarkably improved under the condition that the waterproof performance of the waterproof polyester-cotton fabric is not influenced. According to the method disclosed by the invention, the color fastness grade of the waterproof polyester-cotton fabric is effectively improved under the condition that the waterproof performance of the waterproof polyester-cotton fabric is not influenced and the waterproof polyester-cotton fabric has arelatively good utilization effect; the method has a simple technology and is convenient to operate, so that further popularization and application of the method are facilitated.

Description

technical field [0001] The invention belongs to the technical field of improving waterproof polyester-cotton fabrics, and in particular relates to a method for improving the color fastness of waterproof polyester-cotton fabrics. Background technique [0002] Existing waterproof polyester-cotton fabrics are widely used in real life such as: umbrellas, tents and some protective clothing, etc., but waterproof polyester-cotton fabrics, especially waterproof fabrics with higher waterproof levels such as 4 or 5, Then go to the padding working fluid, and there is almost no liquid volume. If the color fastness of the polyester-cotton fabric after waterproofing is not good, it will seriously affect its performance. For example, the umbrella in daily life will fade after being exposed to rain once, and the appearance will be extremely unsightly over time. Therefore, it is necessary to design a method for effectively improving the color fastness of waterproof polyester-cotton fabrics ...
