Hair colouring was carried out by using catechinone prepared from (+)-catechin by enzymatic or chemical oxidation reaction. The difference of dyeability between the catechinone produced by enzymatic reaction (EC) and that produced by chemical reaction (CC) was studied changing the dyeing condition such as dye concentration, dyeing temperature, pH or the sort and concentration of salts. The colour of the hair dyed by EC or CC at 30°C is yellowish or reddish brown, respectively. The colour of the hair dyed by EC and CC is deeper at a higher dye concentration and at a higher temperature. Hair is dyed deepest by EC or CC at the solution pH = 6.04 or 5.45, respectively. The dyeability is increased by adding NaCl (≤4 M) or CaCl2 (≤1 M), while it is decreased by adding AlCl3. The colour fastness of the dyed hair to washing or ultraviolet light is high enough for practical use. Furthermore, it was found that colourants are obtained from tea extracts which contain catechin derivatives. Hair is dyed reddish brown by the colourants.

In order to improve dyeability, polypropylene （PP） fabrics were treated in low-temperature radio frequency （RF） plasma. With air, O2 and argon the fabrics were treated and grafted in acrylic acid plasmas. The influence of treatment conditions, e.g. exposure time, discharge power and different gases, on the fabrics dyeability are also performed. It is noticed that the wettability and dyeability of fabrics are significantly improved after plasma treatment, more hydrophilic is produced by plasma treatment.

This work described the preparation of easily colored meta-aramid(PMIA) copolymers from m-phenylenediamine(MPD),isophthaloyl dichloride(IPC), and 3,4′-oxydianiline(3,4′-ODA) via solution polycondensation in N,N-dimethylacetamide(DMAc). The novel co-PMIAs were obtained in relatively high inherent viscosities ranging from 1.32 dL/g to 2.53 dL/g, which could be easily cast into flexible films with high transparence or spun into fibers. All the newly synthesized copolymers possessed excellent thermal stabilities even better than that of commercial PMIA, with 5% weight loss temperatures higher than 430 °C in nitrogen measured by TGA and glass transition temperature of 267–277 °C measured by DSC. The cast films exhibited good mechanical properties with a tensile strength up to107 MPa and a tensile modulus up to 2.2 GPa. The resultant PMIAs also showed good solubility and better dye ability for cationic dyes.

The hydrophilicity, dyeing and antistatic ability of polypropylene microfibre (PPMF) were improved by plasma-induced vapor grafting with acrylic acid. The effects of plasma discharge time, power, liquid phase acrylic acid temperature and environmental temperature on grafting yield were investigated. The existence of grafted polyacrylic acid (PAA) was verified by ESCA and ATR FT-IR. The morphology of grafted PAA was directly observed by SEM. The wicking test shows that the hydrophilicity of modified PPMF is greatly enhanced. The dyeability test of modified PPMF was carried out using Dispersion Yellow. It was found that the dye uptake ratio is linear to the weight percent of grafting. The antistatic ability was indicated by specific resistance. The specific resistance of modified PPMF was reduced to 10(6) similar to 10(7) Ohm . cm, thus the antistatic ability was considerably improved.

Cationic modifying agent ( PECH- amine) with lower molecular weight and containing less nitrogen was prepared and characterized. The water-soluble cationic modification agent has high reactivity for cotton. Cotton modified by this agent can be dyed under salt-free and neutral conditions with direct and reactive dyes. Dyes in the dyebath could be completely exhausted and a dyeing effluent without residual dyes and salt could be expected.

PET (polyethylene terephthalate) has found wide applications in textile industry due to its excellent properties as well as low price. PET fabrics can be dyed with disperse dyes in an aqueous bath in the presence of a carrier. However, attempts have been made for years to replace the non-environmental friendly carriers with less toxic ones, so that the need for carriers is eliminated. In this study, Hybrane H1500 as a dendritic additive was used to study the dyeing behavior of PET. Fiber grade PET was compounded with different percentages (0.5, 1, 2, and 3) of Hybrane H1500 using an internal mixer. Sample films with 1 mm in thickness were prepared by pressing compounded samples followed by dyeing with a Disperse dye (Samaron Yellow 6GSL 200). The optical measurements of dyed samples were measured by Color-Eye 7000A spectrophotometer. It was observed that, K/S as a dye uptake parameter increased by increasing the percentages of the dendritic additive. The amount of C*(Chroma) increased while the ho (hue) did not change too much. The dyeability of prepared samples was attributed to the decrease in glass transition temperature of polymer as studied by analytical technique.
