Dyestuff Knowledge Center

If you work in textiles, leather, or paper manufacturing, the question is never simply "which colour?" — it is always "which dye chemistry, and why?" The wrong choice of dyestuff costs you in re-dyeing, poor fastness, customer returns, and failed quality audits. The right choice — matched precisely to your fiber, your process, and your end-use requirements — delivers consistent results, batch after batch, across every market you serve. At Avi Chemicals , we have been manufact

Introduction Selecting the right textile dye is essential for achieving consistent color quality, durability and production efficiency. Different fibers require different dye types , and choosing the wrong dye can lead to poor shade development, low color fastness and production issues. Textile manufacturers commonly work with fibers such as cotton, wool, nylon and blended fabrics. Each of these materials has different chemical properties, which means the dye selection proces

The global textile industry uses multiple dye classes depending on fiber type, application, cost, and fastness requirements . Among the most commonly used dyes are: Reactive dyes Direct dyes Acid dyes Understanding the difference between these dye types helps textile manufacturers choose the right dye for performance and cost efficiency . In this guide, we explain the key differences, applications, and selection criteria used by textile dye buyers worldwide. Reactive Dyes Rea

Introduction The textile industry uses different classes of dyes depending on the fiber type, dyeing process, and performance requirements . Among the most commonly used dyes are acid dyes and reactive dyes , both of which play an important role in modern textile processing. While both dye classes produce vibrant colors, they are designed for different fibers and dyeing mechanisms . Understanding the differences between acid dyes and reactive dyes helps textile manufacture

Introduction Reactive dyes are one of the most widely used dye classes in the textile industry , especially for dyeing cotton and other cellulosic fibers. These dyes are known for their excellent colour brightness, strong colour fastness, and high washing resistance , making them ideal for modern textile production. Reactive dyes chemically bond with the fiber during the dyeing process, creating durable colors that remain stable even after repeated washing and exposure to l
