Bright Color in Dyeing

Evaluation of Color Sensitivity to Dyeing Parameters in Natural Dyeing with Anthocyanin

Dyeing Properties and Color Fabrics Using Natural Dye and Mordant

An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Fabrics dyed using myrobalan extract as natural mordants and green dye. A red color were obtained by using theses mordants. The color of dyed fabrics was investigated in CIELab L, a and b and K/S values. Finally, all dyed fabrics were tested for wash and light fastness properties as per ISO standard t...

Rubia Tinctorum L. (Rubiaceae) or Madder as One of the Living Color to Dyeing Wool

The medicinal part of Rubia tinctorum is the dried root. The small yellowishgreen flowers are in loose, leafy, long-peduncled terminal or auxiliary cymes. The margin of the calyx is indistinct, 4- to 5-sectioned and has a tip that is curved inward. There are five stamens and an inferior ovary. The fruit is a black, pea-sized glabrous, smooth drupe containing two seeds. The perennial pl...

Research on Computer Color Matching in Textile Dyeing by the Method of Regression Analysis

In the study of color matching in textile dyeing, regression algorithm is used to analyze the nonlinear relationship between the dye concentration and the color data in CIE-La*b* color space of dyeing sample, thereby providing theory basis for establishing mathematical model for textile dyeing. Statistical analysis is conducted on a number of experimental data and the model is tested by actual ...
