Dyes and pigments are the two colourant sources used in a wide range of household and commercial applications. There are different categories among each of them and a suitable type is selected depending upon the needs of the application.
Among dyes, there are basic dyes, solvent dyes, reactive dyes, acid dyes, vat dyes, disperse dyes and many more. Most of them have wound their way into the printing, textile, plastics, leather, polish, automotive industries and more; the list is almost endless. However, there are some dyes which are best suited for certain industries, for example, the most frequently used application of solvent dyes is the plastics industry. Solvent dyes are soluble in organic solvents and this very characteristic enhances their versatility.
Foil printing, marking pens, printing inks, candles, leathers, polishes, varnishes, acrylic resins, wood stains are some other applications where solvent dyes are used. In the plastics industry, solvent dyes proves highly useful as it lends colour to a number of solid materials like polyester, nylon, acetates, PETP, PVC, PMMA, styrene and polystyrene monomers. Solvent dyes are additionally a very popularly used item in medical diagnostics to manufacture stains that go towards identifying varied components of the cell structure. They come in colours of red, blue, yellow and green with new uses and applications being constantly discovered for this type of dye. A standardized pattern is followed in the naming of the dye; the dye colour appears first and this is followed by its distinguishing number. For example, several shades of red solvent dyes are differentiated from one another by the number that follows the name like Solvent Red 49, Solvent Red 1 and Solvent Red 24 etc.
Another example of the dye and its most popular application that can be given here is the reactive dye and its use for a diverse range of textile fabrics. Reactive dyes are of plant origin and regarded as the best suited dyestuff for textiles. It works superlative on fabrics like cotton, linen, bamboo, jute, hemp, silk, rayon etc. its characteristics of wash fastness and colour fastness make it an ideal choice for cotton and additional plant fabrics. It comes in the powder and liquid form and also in the form of print paste. Absorption into the fabric is facilitated through a chemical reaction. There are a number of chemicals that are popularly applied with reactive dyes such as Ludigol, Urea, dye fixer, Sodium Alginate, Synthrapol detergent and water softeners with each of them fulfilling a specific function. All of them together help in enhancing the vibrancy and brightness of the colours used for the application.
Different categories of dyes and pigments go towards the varied applications; however, they all have one thing in common and that is top quality. All colorants produced by several manufacturers are tested on several parameters before they are released for use. All solvent dyes manufacturers, reactive dyes manufacturers, pigment blue manufacturers and other related manufacturers give full guarantee of the quality of their products. You can safely avail any of them and be sure that it works best for your application.
