This research work involves the dyeing of wool yarns with saffron petals as a source for green color. At first step woolen pile yarns treated with four different mordents, namely: tin chloride, copper sulfate, aluminum sulfate and iron(II) sulfate in acidic condition using acetic, oxalic, citric and lactic acids respectively. In this study the possibility of using saffron petals as a natural dy...
Investigation into the Dyeing of Soybean Fibres with Natural Dyes and their antimicrobial properties
The dyeing behaviour of annually renewable soybean protein fibres with Madder, Weld and Walnut seed husk, natural dyes, were investigated and their possible antimicrobial effects were evaluated. The results obtained from the dyeing of the Madder on the soybean fabric were compared with those on a wool fabric. It was shown that the amount of the amino acid content of the fibre has a great effect...
While dyeing of poly(ethylene terephthalate) (PETP) fibres in supercritical carbon dioxide is now on its way to be transferred into the textile finishing industry to check the economic efficiency and practicability in an upscaled plant, dyeing of natural fibres such as cotton is still a problem. Within the paper an overview is given about the international stateof-the-art of dyeing technical (a...
This paper presents a model of cloth dyeing using the characteristics of the thread and weave pattern. The proposed dyeing model is based on Fick’s second law that defines the molecular transfer under translational diffusion [Fic85]. The algorithm in the proposed model calculates the dyeing distribution from parameters such as the amount of dyeing, saturated amount, and pressure in each cell on...
Newfangled vinylsulfone (VS) based fiberreactive dyes were synthesized and applied to mill desized, bleached and mercerized textile fabric (100% cotton). Padthermosol dyeing method was utilized due to less hazardous environmental affects and high dye fixation to optimize dyeing quality parameters i.e. salt concentration, pH, dyeing time and dyeing temperature. The pretreated and dyed cotton fab...
