The main challenge in dyeing polyester () fibers is the inability of dyestuffs to reach the fiber core or their irregular accumulation on the surface due to the density of the fiber structure. CRN CARRIER BB is a high-performance, eco-friendly "Green Carrier" developed to maximize the mobility of disperse dyestuffs within the fiber.
Maximum Diffusion and Migration Potency
CRN CARRIER BB acts not only as a carrier but also as a powerful leveling agent.
Rapid Diffusion: Accelerates the movement of dyestuff molecules from the outer surface of the fiber toward the core (diffusion). This increases color depth, especially in tightly woven fabrics and high-twist yarns.
Superior Migration: Enhances the ability of the dyestuff to relocate (migrate) between fibers during the dyeing process. This prevents the formation of "barré" or color unevenness, ensuring a homogeneous appearance.
"Green" Technology and Sustainability
Unlike traditional aromatic carriers, CRN CARRIER BB fully complies with modern environmental regulations.
Eco-Friendly Composition: Its biodegradable structure reduces the wastewater load and protects ecological balances.
Odorless and Safe: Contains no heavy phenolic odors, preserving indoor air quality and worker health.
Fiber Protection: Allows polyester blends sensitive to high heat (such as wool/PES or acetate/PES) to be dyed at lower temperatures without damage.
Key Advantages of CRN CARRIER BB
Low-Temperature Advantage: Enables effective dyeing under atmospheric conditions or at low pressure () without the absolute need for HT machinery.
Corrective Capability: Due to its high migration power, it delivers excellent results in "re-leveling" or rectification processes intended to fix dyeing defects.
Excellent Fastness: Helps dyestuff become deeply embedded within the fiber structure, assisting in maintaining optimal washing and rubbing fastness levels.
No Impact on Light Fastness: Leaves no residue on the fabric, thus ensuring that the light fastness values of polyester materials are not compromised.
