![Preventing Color Stains in Dyed Cotton [Reactive Dye & Ozone Tips]](https://atira.in/wp-content/uploads/2024/09/Understanding-Reactive-Dye-and-Ozonolysis-Issues-368x240.jpg)
Color staining and discharge stains in stitched dyed cotton garments are a common challenge, especially when dealing with reactive dyes. A typical issue is the development of light to medium pink stains post-finishing, which occurs after garment making. The root cause often lies in the cleavage of azo groups (chromophores) and unsaturated carbon-carbon linkages. Although stains form in a seemingly […]
Environmental protection and product safety are becoming increasingly important criteria in the purchase of textiles, due to the emotive nature of the debate and greater consumer concern. This article provides general information about azo dyes to help put the issue on a more factual basis. Here you will also find some background notes about the German Consumer Goods Ordinance (GCGO), […]
Ever wondered how digital prints look so amazing? It’s a blend of science and creativity that goes beyond the surface. From traditional printing methods to modern digital techniques, achieving those vivid colors involves a mix of chemistry, artistry, and careful choices. Let’s dive into the world of printing thickeners like sodium alginate, clever additives, and the way chemistry and art […]
Welcome to our blog, where we will delve into the world of natural dyes and the crucial role they play in our daily lives. Natural dyes are derived from natural sources such as plants, insects, and minerals and have been used for centuries to color fabrics, textiles, and other materials. Today, natural dyes are becoming increasingly popular as they are […]
Humans have been fascinated by color since prehistoric times. This is justified by the use of colors in various clothing & apparel, furnishings, artifacts, plastics, and paper products. The initial source of colorant was vegetables and other origins. After the discovery of synthetic dyes, the initiative by researchers overall contributed to the development of more than 10000 chemically different dyes […]
Pigment Printing industry can adopt new technology of fixation by UV (Binder) to achieve energy saving by replacing high-temperature curing and thus become environmentally sustainable. The area of fabric processing particularly dyeing and printing, are the most value-added processes as they make products most pleasant & attractive to consumer choices. Generally, the dyeing is covering full substrate by immersion into […]
Synthetic thickeners are usually extremely high-molecular-weight polymeric materials able to develop a very high viscosity at a relatively low concentration. However, the printing paste is hard to dispose of that generates sedimentation to the water streams during disposal of its wastes which influence the water quality leading to harmful environmental impacts. Therefore, as a substitute for synthetic thickeners, natural biodegradable […]
