In textile pre-treatment, purging cellulosic fibers (cotton, linen, viscose, etc.) of their natural impurities is the most critical stage in determining dyeing and printing quality. CRN CLEAN CFD is a non-ionic surfactant specifically formulated for cellulosic bleaching and preparation, distinguished by its exceptional stability in alkaline environments.
Maximum Efficiency in Cellulosic Bleaching Processes
The bleaching of cellulosic fibers is typically conducted at high pH values and elevated temperatures. CRN CLEAN CFD maintains its molecular integrity and efficacy under these harsh conditions:
Excellent Wetting and Penetration: Rapidly lowers the surface tension of the fabric, ensuring the bleaching bath permeates deep into the fiber pores uniformly within seconds.
Non-Ionic Character: Due to its non-ionic nature, it exhibits high compatibility with both anionic and cationic auxiliaries, maintaining bath stability without precipitation.
Superior Scouring and Emulsification
The product is designed to detach and remove natural waxes, oils, pectins, and seed fragments from cellulosic fibers.
Oil and Dirt Dissolution: Breaks down contaminants on the fiber and holds them in a stable emulsion within the bath.
Reduction of Spotting Risks: Prevents dissolved impurities from settling back onto the fabric (redeposition), ensuring a smooth and pristine base prior to dyeing.
Key Advantages of CRN CLEAN CFD
Alkali Resilience: Functions without losing stability in bleaching baths containing caustic soda ($NaOH$) and peroxide.
Superior Hydrophilicity: Imparts excellent absorbency to the fabric post-treatment, enhancing dyestuff yield and fastness in the dyeing stage.
Foam Management: Provides ease of operation in both discontinuous (jet, overflow) and continuous systems with its controlled foam level.
Excellent Rinseability: Rapidly detaches from the fabric, promoting water savings and optimizing process duration.
