吸色片在衣物洗涤中防串色性能及作用机理OA

To address the problems of color transfer and fading during clothing washing,this study system-atically investigated the adsorption characteristics of color-absorbing sheets for different types of dyes,the in-hibitory effect on color fading of different material clothing,and the anti-color transfer performance in mixed washing scenarios.Through methods such as absorbance testing and K/S value determination,the upper limit of adsorption by color-absorbing sheets for nine types of dyes including direct,reducing,reactive,and acid dyes was explored.The fading patterns of cotton,wool,polyester,and denim materials and different colored clothing were analyzed.The anti-color transfer effects of color-absorbing sheets in single-washing and mixed-washing scenarios were compared.The results showed that the adsorption capacity of color-absorb-ing sheets for dyes was closely related to the dye structure.The adsorption amounts of reactive,acid,and sulfur dyes were relatively high(up to 26.192 mg),while the adsorption capacity of indigo and coating dyes was rela-tively low(minimum 0.025 6 mg).The amount of clothing fading was related to the material and color depth,with dark cotton fabrics and denim fabrics having the most significant fading.In the single-washing scenario,color-absorbing sheets could reduce the K/S value of color transfer on cotton,wool,and polyester substrates,with a maximum reduction of 65.7%.In the mixed-washing scenario,they could effectively adsorb free dyes and reduce the probability of local color spots formation.Color-absorbing sheets captured free dyes in water through a combination of physical adsorption and chemical action,thereby blocking the transfer of dyes be-tween clothing.This study provided data support for the optimization and upgrading of color-absorbing sheet products and laid a foundation for the formulation of clothing anti-color transfer washing technology standards.
