In this article the extraition of DMF aqueous solution、 UV、 reactive TLC and IR were used in the examination of reaction between active groups containing acid dyes and DMDHEU finishing agents.

Dyeing properties of acid dyestuffs on cationic ramie fiber;

Acid releasing effect of ester compounds and its influence to dyeing with weakly acid dyes;

Development of levelling agent for acid dyes;

One-bath acid dyeing and anti-crease finishing of cotton fabrics;

Dyeing behavior of low temperature plasma modified acrylic fibers with acid dyes;

In order to investigate the existent forms of dyestuff and the combinative forms between dyestuff and wood molecules when wood is dyed, Populus tomentosa stained with two different kinds of acid dyestuffs by vacuum-immerser was studied,and the infrared spectra of wood and dyed wood were analyzed by FTIR.

PTAM was blended with polyacrylonitrile (PAN) and spun into blend fiber which was dyed with acid dyestuff.

Influence of ultrasound in wool dyeing with weak acid dyes;

The dyeing process and the performance of weak acid dyes using additive WMJ for wool at low temperatures are studied.

Results show that dyeing process with direct dyestuff and weak acid dyestuff in one bath can impart the polyamide/ cotton mixture good colorfastness and levelness,as well as lowered energy consumption and production cost.

Photocatalytic degradation of acid black dyes by the functional material of titanium oxide;
