What is disperse print fabric?
Disperse print fabric refers to textiles (primarily polyester or blends) printed using **disperse dyes** that sublimate under heat, bonding with synthetic fibers at a molecular level. This technique is renowned for vibrant colors, sharp details, and durability.
Below is a detailed technical and commercial overview based on industry sources:
1. Core Properties & Production Process:
Material Composition: Predominantly 100% polyester, enabling high dye affinity.
Key Techniques:
Direct Inkjet Printing: Uses disperse dye sublimation inks; requires fabric pretreatment (e.g., 1–2% nonionic activator) to prevent ink bleeding and boost color depth .
Transfer Printing: Designs printed on paper, then heat-transferred (e.g., 240°C for 30 sec) onto fabric .
Blend Fabric Printing: For polyester-cotton blends, fabrics are modified (e.g., benzoylthioglycollate) to accept disperse dyes .
Critical Parameters: Optimal weight ranges 70–290 GSM, with widths customizable up to 3.2m .
