Very high heat stability
Spinning melts run extremely hot, so only pigments stable at polyester or polyamide spinning temperatures keep shade without decomposition.
Industries
Organic pigments for synthetic fibres sourced from India with grade selection, documents, and export support.
Dope-dyeing (mass colouration) of polyester, polypropylene and polyamide melts is one of the most demanding pigment applications because colour is added before spinning, then forced through fine spinnerets at very high temperature. Pigments must therefore have exceptional heat stability, extremely fine particle size, and no filter-clogging agglomerates. Organic pigments give bright, washfast, lightfast fibre shades that no surface dye matches for durability. Buyers sourcing from India should confirm high-temperature stability for the polymer, spinnability with low filter-pressure rise, and strong light and wash fastness.
At a glance
Spinning melts run extremely hot, so only pigments stable at polyester or polyamide spinning temperatures keep shade without decomposition.
Colour passes through fine spinnerets and pack filters, so tightly milled, agglomerate-free pigment prevents filter-pressure spikes and breaks.
Mass-coloured fibre is washfast and lightfast throughout, so shade survives laundering and sun far better than surface dyeing.
Delivered as fibre-grade masterbatch matched to your polymer, ensuring even distribution and predictable colour at high draw speeds.

It must withstand spinning-melt temperatures without shade change, be milled fine enough to pass spinneret and pack filters without pressure rise, and disperse evenly in the polymer. High light and wash fastness then come built into every filament rather than applied on the surface.
Because pigment is locked inside the fibre, mass-coloured yarn resists washing, light and rubbing far better than surface dyes, uses less water, and gives very consistent colour. It suits carpets, automotive textiles and technical fibres where durability outranks shade flexibility.
Polypropylene needs heat-stable, non-blooming, low-migration organics such as selected phthalocyanines, high-performance reds and stable yellows. Because PP has no dye affinity, mass pigmentation is effectively the only route, so confirming spinnability and fastness in your grade is essential.
Yes. Fibre applications generally use polymer-matched masterbatch rather than raw powder, giving fine dispersion and stable filter behaviour. Specify your polymer, denier and spinning temperature so the carrier and loading are tuned to your line before trials begin.
