Eco-Friendly Textile Dyeing Process Introduction: Dyeing and finishing processes in the textile industry have attracted a lot of attention lately as the concept of sustainable and eco-friendly textiles and garments are gaining popularity. Here we will focus today on eco-friendly textile methods which are a widely discussed topic for the present. The textile industry is […]

The Dyeing Process of Disperse Dyes The dyeing of hydrophobic fibres like polyester fibres with disperse dyes may be considered as a process of dye transfer from liquid solvent (water) to a solid organic solvent (fibre).Disperse dyes are added to water with a surface active agent to form an aqueous dispersion. The insolubility of disperse […]

Dyeing Of Polyester Fabric With Disperse Dyes (Carrier Method).   Objects : To dye a material practically. To observe the practical advantages and disadvantages of this dye. To compare the theoretical idea with practical experiment.   Introduction :     Dyes are coloured, unsaturated organic chemical compounds capable of giving colour to a substrate (a textile), i.e. […]

Zero PP technology refers to innovative processes that eliminate potassium permanganate (KMnO4) in denim washing. Potassium permanganate, a widely used bleaching agent, raises environmental concerns due to its toxicity and non-biodegradability. Zero PP technology uses alternative methods and chemicals to replicate the bleaching effect while maintaining sustainability. This technology reduces the environmental footprint by eliminating harmful chemicals and minimizing water and energy consumption.

Printing On Polyester Fabric With Disperse Dyes Introduction: Dyes are coloured, unsaturated organic chemical compounds capable of giving colour to a substrate (a textile), i.e. colouring or dyeing it. The term “disperse dye” have been applied to the organic colouring substances which are free from ionizing groups, are of low water solubility and are suitable […]

Natural Color Substances for Textile Materials EXPLORATION TEHNIQUE NATURAL DYES SUBSTANCE OF PLANTS IN AROUND US FOR DYEING TEXTILE MATERIALS According to the source of the textile dye is classified into 2, namely: First, Natural Coloring Agent (NCA) is a dye derived from natural materials in generally from the extracts of plants or animals. Second, […]

It is also called ‘artificial silk’. Regular rayon is called viscose rayon. Some rayon is made by using the cuprammonium process and is called the cupro […]

Introduction to Sulfur Dyes Sulfur dyes are complex heterocyclic molecules or mixtures formed by melting or boiling organic compounds containing amino or nitro groups with Na-polysulphide and Sulfur. Sulfur dyes are so called as they all contain Sulfur linkage within their molecules.             Sulfur dyes are highly coloured, water insoluble compounds and have to be […]
