High-strength disperse dyes for polyester, PET blends, nylon and microfibers. Competitive factory prices, ISO quality control and technical dyeing support.
Key features you can highlight on product pages and datasheets:
Disperse dyes are low-solubility dyes designed to color hydrophobic synthetic fibers. They are the industry standard for polyester, acetate and certain polyamide blends. Unlike direct or reactive dyes used for cellulosics, disperse dyes penetrate polymer matrices by diffusion (often aided by temperature or carrier), producing bright, wash-fast shades on thermoplastic fibers. When listing product applications on your page, specify recommended substrates (e.g., PET, PBT, acetate) and any known limitations (e.g., poor affinity for cotton without a carrier).
Migration and poor fastness usually stem from over-exhaustion, improper carrier use, or inadequate fixation.
A compact, repeatable lab procedure helps R&D and procurement compare dyes quickly.A typical mini-trial includes:Sample size: 50–200 g fabric swatches (pre-scoured).
