Reactive Dyestuffs

At present, cotton, rayon, and cellulosic fabric are mostly dyed by reactive dyes. Reactive dyes could provide a bright shade with high washing fastness and rubbing fastness but, on the other hand, the dyeing costs of reactive dyes is higher incurring from the cost of labor, dyestuff, chemical auxiliary, and water treatment. Hifix dyes have been developed to reduce those costs by having a wide selection of the dyestuffs in order to match with dyeing process, dyeing machine, and customer requirement which, therefore, will reduce errors during production, increase productivity, save time and energy, and reduce expense at the same time.

Disperse Dyestuffs

Hicron dyestuffs of Phisit Intergroup are disperse dyestuffs for polyester fiber with variety of shades and excellent properties. There are rich variety of Hicron dyes covering a wide-range of color shades so as to meet different requirements for various dyeing processes. It is therefore recommended to select appropriate dyes for each end use and application process.

Acid Dyes

Unimide and Uniset dyes are Acid dyes that are highly water soluble, and have good light fastness. Acid dyes are effective on protein fibers such as wool and silk. They are also used for polyamide and spandex dyeing.

Direct Dyes

Although reactive, direct, sulphur, vat or naphthol dyestuffs can all be used for cotton dyeing, recently cotton has been being dyed with reactive dyes for the most parts due to their bright shades and high wet fastness property. However as the labor, dyestuff, and chemical cost are increasing, direct dyes can be a good choice for cotton dyers. Direct dyes can be used economically and simply for the dyeing of cellulosic fibre with practical level of colour fastness. The application of direct dyes to cotton dyeing will bring economical benefits as it can reduce dyeing-cost in terms of time and money.

Vat Dyes

Vat dyestuffs are water-insoluble and they are soluble only in its reduced form or leuco salt form. Solathrene Dyes are Vat dyes for cellulose fabric that give the-best-in-class washing fastness and light fastness properties. Solathrene has a super fine molecule so it can easily diluted and changed to Leuco Vat form. Uniform, level dyeing of cellulosic fabrics and blends by continuous dyeing process Super fine, micro-molecular particle size to ensure stable dye dispersion, ease of reduction, and speck free performance. Ready to use, easy to handle, non-dusting, non-foaming and non mal-odorous dyestuff. Highly recommended to achieve and meet stringent quality/fastness demands: especially to light, repeated washings, laundering, post bleaching etc.

Basic Dyes

Basic dyes are cationic dyes that are mainly used for dyeing acryric fiber and cationic dyeable polyester fiber (CDP). Cationic dyes are water-soluble dyestuffs with bright colours. Cationic dyes can be classified into two groups: Triacryl X and Triacryl AD based on their dyeing properties on polyacrylonitrile fiber.

Other Dyes


Pretreatment process is the first and most important step for textile dyeing and finishing. As it can affect the outcome of the final products in terms of shade, colour yield, hand-feel etc., the chemicals in pretreatment process play an important role. Phisit Intergroup has a wide variety of textile chemicals for pretreatment process and they can be categorised into the following groups.

Dyeing is the second step of textile dyeing and finishing. Not only dyestuffs will be used in this step, but also many textile chemicals will be used in the process as well. Dyeing chemicals are mandatory in order to ensure that the quality of textiles meet customers’ requirement such as colour levelness, washing fastness etc.

Finishing process is the final step of textile dyeing and finishing. This step is necessary to assure that textile are soft handle which, in this case, can be provide by softener chemicals. Besides soft handle, other finishing chemicals can produce special textile effects such as wrinkle free, flame retardant, water repellent, anti-microbial etc.
