Hollow fibers have been used in rather different fields of general textile use and in special-purpose products because of their unique structure. Hollow fibers have profitable properties for some applications because of their large surface/volume ratio. In this paper, dyeing properties of nylon hollow fiber were investigated. Nylon regular fiber and hollow fiber were used in the dyeing experiment. The samples were dyed with three kinds of acid dyes. Effects of dyeing temperature, pH of the dye bath, and dye concentration on dyeing properties were examined.

The study has attempted to compare the behavior of reactive, disperse and acid dyes when wastewater from these three kinds of typical dyestuffs were treated by chemical coagulation and NF membrane in pilot scale. Disperse dyeing wastewater showed the tendency of easier removal in TOC and COD and especially in color.

Four different subtilisins of protease were investigated to see their effects on the cleaning activity. The cleaning solution was formulated with various non-ionic surfactants and other additives such as propylene glycol, triethanolamine, pH balancer etc. to evaluate their effect on enzyme activity as well. Evaluation of formulated cleaning solution was carried under K0120 using pre-soiled textiles from EMPA. The results showed that the cleaning activity on soil removal was not severly influenced by surfactant but the enzyme mostly. In addition, the activity of enzymes was not much affected by the type of surfactants as long as the surfactants were non-ionic. Liquinase among the four enzymes used in this study showed the best performance on soil removal, especially blood stain.

In the presence of heat and oxygen, phosphorous compounds decompose to form water vapor and phosphorous oxides. The phosphorous oxides subsequently reat with the polymer matrix and dehydrate it, reforming phosphoric acids. These acids again decompose to reform water vapor and phosphorous oxides. Ultimately as the water available from normal combustion of hydrocarbons diminishes, the phosphorous oxide reat with hydrocarbon fragments to produce a very high melting point char at the interface between the polymer and the heat material. The chars, which contain phosphorous, rapidly dissipate heat energy and lose their glow. This antiglow property of phosphorous compound contributes to its availability as a flame retardant. In this study, the acrylated phosphorous compounds will be prepared and demonstrated as flame retardants.

The study has focused on the dyeing properties of 4 kinds of high temperature type mono azo disperse dyes, widely used in the dyeing factory, under the ultra low liqour ratio (1:4) dyeing condition.
