(1) We used cheap p-methyl cinnamic aldehyde as starting material, through a two step reaction (brominated, halogenated of ethers) to graft two bio-compatibility of dyes, by which we got the target of reactive dye A and B;
(2) we selected three protein fibers such as hair, silk, and skin powder to react with p-methyl cinnamic aldehyde . We used single-factor experiment to get the best reaction conditions .Based on that condition, fiber reactive dyes and proteins (silk, wet blue) was dyed .

With cheap methyl cinnamic aldehyde as the primary material, through two -step reaction (brominated, halides by grafting), grafted two kinds of biological compatibility of dyes, obtained the target fabric  reactive dyesA, reactive dyes B ;
(2) Select  white hair, silk, leather powder three protein fiber to react with p-methyl cinnamic aldehyde,choose the optimum reaction conditions through the single factor experiment ,  regard it as a basis of  the dyeing-reaction conditions of reactive dye and protein fiber (silk, lwet blue eather )
如若这般,当初又为了什么?
