Solution Dyed Colored Acrylic Yarn

Leveraging advanced solution dyeing technology, we achieve integrated production of pre-spinning dyed acrylic fibers, giving the fiber uniform and stable color from the source, avoiding problems such as color flower and poor color fastness in post-dyeing.

Core Technical Advantages

Technical Highlights	Process Value	Performance Indicators
Masterbatch Mixing Technology	Using German imported masterbatch dispersion equipment, particle size control ≤5μm, fiber coloring uniformity increased by 40%	Color difference ΔE≤0.5 (D65 light source), consistent batch-to-batch color fastness
High Temperature Spinning Stability Process	Masterbatch heat resistance ≥220℃, no color migration or decomposition during spinning process	Sunlight fastness ≥6 grade, water wash fastness ≥4 grade (ISO standard)
Environmentally Friendly Coloring System	The whole process does not contain harmful chemicals such as APEO and azo compounds. It has passed OEKO-TEX® Standard 100 certification	Heavy metal residue ≤0.1ppm, complies with EU REACH regulations

Product Specifications

Fineness Range: 1.2-3.3D (Ultrafine / Coarse specifications can be customized)
Color System:
- Basic Colors: Black, white, gray, navy blue, sapphire blue etc., over 50 regular colors (always in stock)
