Acid Dyes - Water Soluble Anionic Dyes For Protein Fibers Non-toxic And Safe For Food Coloring Requires Mild Acids For Dye Setting

Highly regarded as one of the trustworthy names engaged in manufacturing exporting and supplying a considerable assortment of Acid Dyes in Vapi Gujarat India. Offered Acid Dyes are water soluble anionic dyes that are applied to fibres such as silk wool nylon and modified acrylic fibres from neutral to acid dye baths. Attachment to the fibre is attributed at least partly to salt formation between anionic groups in the dyes and cationic groups in the fibre. Water soluable Acid dyes are not substantive to cellulosic fibres. Acid dyes are used both commercially and by the studio dyer to dye protein/animal fibers such as wool silk mohair angora alpaca and some nylons and synthetics. Acid dyes require the use of an acid such as vinegar acetic or sulphuric acid to set the colour.

Acid dyes sound scary to some novices who imagine 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 fiber. Some of them are significantly more toxic than fiber reactive dyes while others are even safe enough to eat and are sold as food coloring.
