Title: The Influence of Microwave Heating on Dyeing Time and Dyeing Rate in Cotton Fabrics
Abstract: Relevant researches show that microwave heating caused certain effect on reactive dyes' dyeing rate.In order to verify the above viewpoint, this paper designed the following experiments: study microwave solid color dyeing, microwave fixation conventional dyeing, dyeing conventional microwave fixation with conventional dyeing process as reference, in order to investigate microwave heating's influence on dyeing rate and dyeing time in cotton fabrics.Experimental results show that compared with conventional dyeing fixation, microwave dyed solid color will reduce fixation time, and increase per unit time of reactive dyes dyeing rate on cotton fabric.The integrated use of conventional technology and microwave technology can reduce dyeing time or fixation time as well as ensure dyeing rate.With the development of science and technology, microwave components improve the performance and at the same time constantly reduce cost, which lays a solid foundation for the wide range of application and popularization of microwave, and greatly facilitates life and production in China.In dyeing industry, the earliest application of microwave was in textile material drying, and as dyeing technology and development of microwave technology, it was applied to dyeing and fixation.Rapid heating with microwave changes additives molecular orientation, and makes it speed up the movement and increase friction, and then achieves the goal of rapid dyeing fixation.
