Abstract

The invention relates to a finishing method used for increasing woolen knitwear color fastness. The finishing method used for increasing woolen knitwear color fastness comprises following steps: woolen knitwear is subjected to washing with an aqueous solution containing a strong decontamination essence; steam is adopted for at least of steaming treatment of the wolen knitwear; an aqueous solutioncontaining a fabric raising agent is adopted for washing; an aqueous solution containing a fabric resin finishing agent is adopted for washing; and dehydration and drying are carried out. According tothe finishing method, fiber surface and internal treatment of woolen knitwear is carried out through specific water washing process, so that the resistance of the woolen knitwear on light is improved, azo active dye bond broken caused by sunlight reduction is delayed, the stability of the dye in the woolen knitwear in water and acid and alkali solution is improved, the amount of dye floating color and colorful fiber micro particles fallen in woolen knitwear friction process is reduced, and comprehensive improvement of woolen knitwear color fastness is achieved.

Description

technical field [0001] The invention relates to the technical field of textile finishing, in particular to a finishing method for improving the color fastness of wool knitwear. Background technique [0002] According to the requirements of the FZ / T 73018-2012 "Wool Knitwear" standard in the textile industry, the color fastness to perspiration, water, rubbing, light and dry cleaning of first-class products can reach level 3 is qualified. However, the color fastness of some wool knitted garments for inspection cannot meet the standard, resulting in serious discoloration of the clothes during wearing and washing. This quality problem will seriously affect the performance of the product, seriously affect the customer's experience of using the product, and thus affect the brand reputation. . Therefore, there is an urgent need to develop a method for improving the color fastness of wool knitwear. Contents of the invention [0003] Based on this, the purpose of the present inv...
