Disperse Dyes , Reactive Dyes

here are some prominent companies in Pakistan involved in Disperse Dyes and Reactive Dyes, along with their likely business type (Manufacturer/Factory or Trading Company). Please note that the distinction can sometimes be blurred, as some manufacturers also trade, and precise, up-to-the-minute classification requires direct confirmation. This list is based on publicly available information and general industry knowledge.

the information about the types of Disperse and Reactive Dyes typically produced or sold by companies in Pakistan, presented in English:

Disperse Dyes (Primarily for Polyester, Acetate, and sometimes Nylon/Acrylic)

Companies in Pakistan involved in the manufacturing or sale of Disperse Dyes generally offer products covering various application needs:

1. By Energy Level/Sublimation Fastness:

Low Energy Dyes (E-type/A-type): Suitable for carrier dyeing at lower temperatures, good migration, typically lower sublimation fastness. Used for acetate and sometimes polyester blends.

Medium Energy Dyes (SE-type/B/C-type): Most widely used for polyester, applied at high temperatures (120-130°C), good build-up and fastness properties. Suitable for exhaust dyeing.

High Energy Dyes (S-type/D-type): Applied at higher temperatures (around 130-140°C), exhibit high sublimation fastness. Used for thermosol dyeing (continuous processes) and applications requiring excellent heat resistance (e.g., automotive textiles, printing).

2. By Application Method:

Dyes for Exhaust Dyeing (package, jet, beam dyeing).

Dyes for Continuous Dyeing (Thermosol process).

Dyes specifically designed for Printing (direct printing, discharge printing).

Dyes suitable for Transfer Printing.

3. Specialized Types:

High Wash Fastness Dyes.

High Light Fastness Dyes (especially for automotive or outdoor use).

Fluorescent/Bright Dyes.

Rapid dyeing types.

Full range of colours: Yellows, Oranges, Reds, Violets, Blues, Greens, Browns, Blacks.

Reactive Dyes (Primarily for Cotton, Viscose, Linen, Silk, and sometimes Nylon)

Companies in Pakistan produce or supply a wide array of Reactive Dyes, often categorized by their reactive group and application temperature:

1. By Reactive Group / Application Temperature:

Cold Brand Dyes (e.g., Monochlorotriazine - MCT based): Applied at lower temperatures (25-35°C), good reactivity, suitable for batchwise (exhaust) dyeing and printing.

Hot Brand Dyes (e.g., Vinyl Sulphone - VS based): Applied at higher temperatures (60-80°C), excellent fixation and build-up, widely used for exhaust and continuous (pad-batch, pad-dry-steam) dyeing.

Warm Brand Dyes: Applied at intermediate temperatures (around 40-60°C), often specific proprietary types or combinations.

Bi-functional Dyes (e.g., VS/MCT, VS/Nicotinic Acid): Contain two reactive groups, offering high fixation rates, good reproducibility, levelness, and often better washing-off properties. Suitable for various application methods.

High Exhaust (HE) / High Fixation Dyes: Designed for maximum efficiency in exhaust dyeing.

2. By Application Method:

Dyes for Exhaust Dyeing (jigger, winch, jet, package dyeing).

Dyes for Continuous Dyeing (Pad-Batch, Pad-Dry-Cure, Pad-Dry-Steam processes).

Dyes formulated for Printing (direct, discharge, resist styles).

Dyes suitable for garment dyeing.

3. Specialized Types:

Dyes with High Light Fastness.

Dyes resistant to Chlorine.

Metal-complex reactive dyes (for specific shades like dull greens, browns).

Full range of colours: Including brilliant shades, deep shades (Navy, Black, Maroon, Reds), and trichromatic combinations for accurate shade matching.

Note: Major international companies (like Archroma, DyStar - though presence might vary) often have significant operations or distribution networks in Pakistan, alongside established local Pakistani manufacturers and suppliers (e.g., parts of larger groups like Sitara, ICI Pakistan in the past, and specialized dye makers). Specific product trade names (like Remazol®, Procion®, Drimarene®, Foron®, Dianix® etc. - these are international examples) would depend on the individual company. For detailed product lists, it's best to contact specific suppliers in Pakistan directly.
