The anionic dye element (R–SO₃⁻) is the only coloured species; the sodium cation plays no function inside the coloration course of action.
Hence a remedy with CuSO4 & CH3COOH in presence of K2Cr2O7 improves the light fastness. When the dichromate is also existing the washing fastness is a little bit enhanced.
The chemical framework of wool is conveniently represented as H₂N–W–COOH, in which ‘W’ denotes the non-reactive central entire body from the wool protein matrix. When wool is immersed in water, the subsequent zwitterionic equilibrium response happens:
Welcome to Textile Coach. In this article, you'll find a wealth of information around the fascinating field of textile engineering, which is the application of scientific and engineering principles to the look and creation of textile products.
Temperature controls the kinetics of dye diffusion and the rate of fibre polymer chain motion, which alongside one another ascertain how speedily dye transfers through the tub towards the fibre.
Wool’s extremely amorphous microstructure (approximately 60–70% amorphous areas by volume) facilitates swift dye diffusion as compared to far more crystalline fibres, while its scaled area morphology requires careful control of dyeing level to prevent fibre hurt at elevated temperatures.

Notice: If you're dyeing wool, a gradual heating and gradual cooling of the dye--bathtub is significant so as not to shock and felt the wool.
The next Attributes outline the acid dye course and figure out its suitability for unique fibre varieties and close-use needs:
The managed crystallinity of nylon does deliver an advantage: it creates a lot more predictable and reproducible dyeing effects throughout batches, making nylon a preferred substrate for precision colour matching inside the attire marketplace.
three. Strong acid dyes: These dyes are applied within a Sulphur Dyes strongly acidic medium and also referred to as leveling dyes; on the other hand, there soaked fastness Attributes really are a limitation. These dyes are Excellent to supply The mixture shades.
Phthalocyanine Acid Dyes — make quite possibly the most good turquoise Sulphur Dyes to blue shades; used exactly where highest brightness is needed together with superior fastness.
