Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. The polymer is formed by free‐radical polymerization in aqueous suspension. The fiber is produced by dissolving the polymer in a solvent such as N,N‐dimethylformamide or aqueous sodium thiocyanate. Acrylic is lightweight, soft, and warm, with a wool‐like feel. It can also be made to mimic other fibers, such as cotton, when spun on short staple equipment. Two ways of obtaining perfectly even distribution to dyestuff in acrylic fiber. Migration properties of the dyestuff can be utilized to get desired effect, provided the dyestuff is not immediately fixed during adsorption on fiber surface and fiber sites having affinity for dye stuffs are distributed evenly in fiber. The build up of dyestuff during first phase of dyeing can be controlled so that no migration takes place after absorption.
Textile Dyes market is projected to grow at a CAGR of 7.25% over the projected period to reach US$7.982 billion by 2022, from US$5.625 billion in 2017.
Textile dyes are used in the process of adding colors to textile products like fibers, yarns, and fabrics. Preference of natural dyes, growing demand for colored textiles and fibers and strong research and development investments in plant based dyes are the factors driving the market, whereas stringent environment laws, production overcapacity and raw materials price volatility are restraining the market growth.
Growing demand for environment-friendly products is boosting the use of natural dyes in textile applications, which in further led to the increase in sales of dyes. Asia Pacific region is expected to witness highest market growth due to the increase in urban households, new applications of textile products and rapid growth in the online fashion market.
