What Is It?
One Bath. Two Colours.
Cationic dyeable polyester (CDP/ECDP) is a chemically modified polyester that accepts cationic (basic) dyes — the same class of dyes used for acrylic fiber — instead of the standard disperse dyes used for regular polyester.
When cationic yarn is combined with standard polyester in the same fabric — as a composite yarn, woven structure or knit — a single dyeing process using both dye types produces two completely different colours simultaneously. This two-tone effect is achieved at no extra dyeing cost compared to a standard single-colour dye process.
The result: rich, dimensional colour effects that would otherwise require yarn-dyeing or double-bath processes. Highly popular for fashion sportswear, outdoor fabric and premium casual wear where visual differentiation matters.

Two-Tone Fabric Result
Two distinct colours from a single dyeing process — no extra cost
🎨 Composite CD+SD Yarn
Our CD+SD composite yarn combines CD and SD filaments in a single yarn — the two-tone effect is built into the yarn itself before fabric production even begins.

Widest Range
CD Bright DTY
50D – 300D
High-lustre bright cationic DTY. The shiny surface amplifies the visual contrast of two-tone colour effects — ideal for fashion fabric, lining and decorative textile where colour and shine combine.

Applications
Where Cationic Yarn Creates Value
Fashion Sportswear
Two-tone colour effects for premium sportswear brands — distinctive visual appearance without complex yarn-dyeing processes.
Outdoor & Casual Wear
CD+SD composite for outdoor jackets and casual wear fabric with textural and colour depth unavailable from standard yarn.
Home Textiles
Upholstery, curtain and decorative fabric where two-tone or melange colour effects add premium visual value.
Suiting & Dress Fabric
CD Bright FDY as warp yarn in suiting fabric — cationic dyed warp against disperse-dyed weft creates subtle two-tone fabric effects.
Activewear & Athleisure
ECDP DTY for solid vivid-colour activewear — cationic dyes produce more saturated, richer colours than disperse dyes on standard polyester.
Woven Lining
CD Bright DTY for fashion lining with colour-contrast inner surfaces — a premium detail for high-end garments and accessories.
Knitwear & Accessories
CD SD DTY in fine deniers for knit scarves, accessories and fashion knitwear with distinctive two-colour textures.
Technical Fabric
Composite CD+SD for technical fabric requiring colour differentiation between warp and weft without additional dyeing steps.

FAQ
Frequently Asked Questions
Cationic dyeable polyester (CDP/ECDP) is a modified polyester that accepts cationic (basic) dyes instead of standard disperse dyes. When combined with regular polyester in fabric, a single dyeing process produces two distinct colours simultaneously — one colour on the cationic component, a different colour on the standard component. This creates two-tone or melange effects at no additional dyeing cost compared to a single-colour standard polyester dye process.
CDP (Cationic Dyeable Polyester) is the standard modified polyester that accepts cationic dyes. ECDP (Easy Care Cationic Dyeable Polyester) is an improved version with higher sulfonate group content, resulting in better dye uptake, more vibrant and saturated colours, improved wash fastness and better dimensional stability. Yaakan's ECDP DTY uses ECDP-grade modified polymer for superior colour performance.
No special dyeing equipment is required. Cationic polyester is dyed in standard polyester jet dyeing machines at the same temperatures used for disperse dyeing (120–130°C). The key difference is the dye formulation — cationic (basic) dyes are added alongside standard disperse dyes in the same bath. Most dye houses that handle polyester can process cationic yarn with minor formula adjustment. We can provide recommended dye process guidelines with your sample.
For woven two-tone fabric: CD Bright FDY (50D/24F) as warp + standard SD DTY as weft is a popular construction. For knit two-tone: CD SD DTY (75D or 150D) interlaced with standard SD DTY gives good colour contrast. For composite yarn (one yarn, two colours): Composite CD+SD DTY (75D–150D) is the simplest approach — the two-tone is built into the yarn. Contact us with your fabric weight (GSM) and construction and we'll recommend the right specification.
MOQ is 1,000 kg per specification for all cationic yarn types. Samples (0.5–1 kg per specification) are available before full order — you pay DHL courier cost only, sample yarn is free. We strongly recommend dye trials before bulk order, as colour results depend on your specific dye formulation and machine conditions. Contact us via WhatsApp or email with your required specification and we'll dispatch samples within 3–5 working days from Xiamen.
