The obtained cationic cotton was dyed with reactive dyes in the ab-sence of electrolyte. The effects of the characteristics of the cationic agent and the pretreatment conditions on dye-ability of reactive dye were investigated. The results showed that the fixation and K/S values of the reactive dyes on the cationic cotton were improved compared with those on the untreated one in the presence of salt. Tests on fast-ness properties of the dyed cotton and fabric quality of the pretreated cotton were carried out and the results showed that wash and rub fastness of the salt-free dyeing were both satisfactory. And anti-crease property,tensile and tear strength,and handling of the cationic cotton were also good compared with that of the untreated one.展开更多

The structures of the new products have been deduced from elemental analysis and spectral dada such as UV-Vis absorption, IR, ^1H NMR, and MS spectroscopy. These dyestuffs gave satisfactory results when applied as disperse dyes to polyester fabric. The dyeing properties such as light fasmess, washing fastness and exhaustion studies have been investigated.展开更多

Experimental results showed that the hair root, hair tip, outer sheath, inner sheath, hair follicle group, fi- brous sheath, outer epidermis, inner epidermis, sebaceous gland and other organiza- tional structures of hair follicles of Hezuo swine can be clearly observed. The hair follicle pore size varied extremely significantly （P〈0.01） among different parts, showing a downward trend of shoulder 〈 body side 〈 buttocks; the hair follicle density ranged from 5.59 to 7.26 hair follicles/mm^2. This study provides reference for the in-dustrial and medical applications.展开更多

The result shows that C.I. disperse red 167, C.I. disperse orange 30, and C.I. disperse blue 284 have dye-uptakes greater than 80%. Therefore, they can be used as the three principal dyes for PLA yams. The experiment discovered that the dyes, because of their Monoazo and ester group contents, have a higher dye-uptake for the PLA fiber. The research on the optimization of dyeing techniques suggests that PLA yarn can obtain a high level of dyeing effectiveness at the following conditions： pH 4- 5, dyeing temperture 110℃ for 30- 40 min. Color fastness to perspiration, and waterwashing fastness increased 1 - 1.5 by the addition of the abstergent FB during the reduction clearing.展开更多

Selecting the fish by only looking at them makes the result analysis based in statistics difficult. Thus, it has become necessary to develop a method of quantification for practical use, which will apply minimal stress to the fish while being economically feasible. The proposed method uses a technique which converts the colors of interest to numerical indexes usable in statistical methods of higher precision. The results increase the abilities of fish nutrition researchers aiming to intensify the color characteristics of fish through selective breeding and genetic engineering with the intent of reliably achieving the desired visual characteristics for commercialization.展开更多
