Synthetic fibers are produced by spinning endless fine fibers from a viscous polymer melt. These synthetic fibers and natural fibers are then spun into yarns for the production of knitted and woven goods. Today's high-speed and cost-efficient processes would be inconceivable without auxiliaries providing lubricant or antistatic properties.

For weaving, the yarns are coated with a protective film, known as size to ensure that they will not be damaged by the high mechanical stresses involved.

Before proceeding to the next steps of dyeing or printing, all natural dirt and processing chemicals have to be washed out. Various wetting, scouring and bleaching agents ensure mild fiber cleaning and a high degree of whiteness. In the dyeing operation, Chromatex processing auxiliaries then make sure that the dye is optimally distributed in the water, is evenly absorbed by the fabric and will not bleed out again during subsequent washing process.

Chromatex finishing products make fabrics luxuriously soft, water-repellent, and stain- or wrinkle-proof. Also garments are given the final character using Chromatex's know how, for example by enzymatic partial removal of indigo dye to give jeans their coveted washed out look.
