Development of Dyeing Mechanism of Wood with Reactive Dyes

The Transmission Theoretical Model of reactive dyes fluid in wood are systemically reviewed in the paper.It also are summarized the dyeing dynamics and thermodynamics and the reaction mechanism of reactive dye liquor with wood.The existing shortages and development direction of dyeing mechanism of wood with reactive dyes are also presented.Wood is a kind of nature porous material with adsorbability and permeability.When dyeing, reactive dyes solution firstly wet, diffuse, adsorb on the wood surface, next permeate into the wood, then react with the hydroxy and the amino in wood fiber, finally fix in the wood.Dyeing effects are affected by the structure of reactive dyes, the structure of wood and dyeing craft [1].Moreover, the dyeing mechanism can guide and regulate the dyeing craft.This paper summarizes the findings of Transmission Theoretical Model of reactive dyes fluid in wood, the dyeing dynamics and thermodynamics and the reaction mechanism of reactive dye liquor with wood.
