Acid Dyes


Acid Dyes

A wide spectrum offered by Venus Dye-Chem comprises of acid dyes, synthetic acid dyes and textile acid dyes at the most frequent prices. Acid dyes are water soluble anionic dyes which are applied to fibres such as silk, wool, nylon & modified acrylic fibres from neutral to acid dye baths. Acid dyes are classified into several classes: 1, levelling acid or strong acid dye 2, super milling or fast acid or neutral acid dyes 3, milling or weak acid dyes. Acid dyes are used in dyeing leather, paper, etc., and their particular value lies in their ability to produce brighter, more uniform colours. They are normally applied from acid dye liquor (acetic, formic, or sulphuric acid); however, unless applied from a neutral or only slightly acid dye bath, i.e., pH of 6.0 to 7.0, their use is likely to result in acid degradation of the material dyed. Acid dyes are used both commercially and by the studio dyer to dye protein/animal fibres such as wool, silk, mohair, angora, alpaca and some nylons and synthetics.

Acid dyes sound scary to some novices, who imaging that the dyes themselves are caustic strong acids. In fact, the dyes are non-caustic, are in many cases non-toxic, and are named for the mild acid (such as vinegar) used in the dyeing process, and for the types of bonds they form to the fibre. Some of them are significantly more toxic than fibre reactive dyes, while others are even safe enough to eat, and are sold as food colouring.
