염색계에 대한 에코로지적 요구

섬유를 염색하는 업계는 우선 염료와 조제의 큰 공급에 직면한다. 지금까지는 염색계로 말하자면 견뢰도와 칼러일드라고 하는 기술적 조건과 비용/색강도비 같은 경제성을 고려해서 선택하면 그만이었다. 그러나 오늘날 고려하지 않으면 안되는 새로운 기준은 일정한 제품의 공급 (품질관리 시스템)과 공급자의 전문지식, 그중에서도 특히 에코로지와 독성에 관한 데..

면의 3색 염색에 대한 염료 흡수의 결정

직접염료에 의한 염색의 기초에 대한 연구는 많다. 그러나 셀룰로오스에 대해 배합염색할 때의 물리-화학적 관계를 조사한 보고는 적다. 예를 들면, 염색조건 특히 섬유구조의 특징을 고려한 염색조건에 관해서 선택적 염료흡착을 조직적으로 조사한 연구는 많지 않다. 본 연구에서는 C. I. Direct Blue 225, Violet 47, Yellow 27의 계와 C. I. Direct Blue 71, Red..

Ultraviolet Enhanced Oxidation for Color Removal of Azo Dye Wastewater

Researchers at the New Jersey Institute of Technology studied the feasibility of using ultraviolet radiation combined with hydrogen peroxide to remove color from a simulated effluent that contained azo dyes. Photochemical reactions initiated by the ultraviolet radiation created hydroxyl radicals that destroyed organic chemicals in the was..

Colour Range Management.

The Marks && Spencer method of evaluating and utilizing color measurement and communication is designed to increase commercial and economic productivity in the fashion industry. This is achieved by determining what color and fabric trends are being developed and designing to meet these trends. Since the application of specific colors onto..

Chapter Six in Colour Physics for Industry, titled Computer Match Prediction - Pigments, comprises an introduction and a conclusion and sections on color measurement of pigmented materials, calculation of the amounts of colorants in transparent madia, translucent and opaque materials, calculation of K and S data for optimum pigment loadin..

Computer Match Prediction - Dyes

Chapter Five in Colour Physics for Industry, titled Computer Match Prediction - Dyes, comprises an introduction and sections on spectrophotometric curve matching, colormetric matching, the starting recipe, reducing cost/metamerism by computer formulation, deviations from linearity in recipe prediction equations, recipe prediction using fl..

Dye-Fibre bonds and their Investigation

Chapter Two in the Theory of Coloration of Textiles, titled Dye-Fibre Bonds and Their Investigation, comprises sections on the historical background and classification of fibers and dyes, the surface energy and the interfacial effect, intermolecular forces (covalent, ionic, ion-dipole, and hydrogen bonds, charge-transfer and van der Waals..

Evaluating Dyeing Processes Ecologically

An investigation evaluates dyeing processes from an ecological perspective. The mass balance of the materials used in the dyeing processes is derived from the load values of the products, as well as from an examination of the pollutant concentrations in the processing baths, which ultimately generate effluent. The investigation indicates ..

The Influence of Moisture Content on the Colour Appearance of Dyed Textile Materials. Part Ⅰ - Dyeing Methods and Reflectance Measurements on Wool.

Researchers investigated methods of determining final fabric color based on the color of fabric while still wet from the continuous dyeing process. To predict the 'dry' color based on a fabric's 'wet' color, a substrate specific curve generated from the change in reflectance of a wool fabric over a full range of moisture contents was used..

SP 110 Dyeing Apparatus for Samples.

In recent years the job of the chemist-dyer-colorist has become almost impossibly difficult. Complications in dye recipes and fiber types combine with the increased division of lots, shorter deadlines, and difficult working conditions to render the job nearly impossible. To help the belabored technician, the Italian firm Ugolini has intro..
