In textile finishing, the use of acid is a fundamental requirement for both adjusting the bath pH and neutralizing the fabric after alkaline treatments. CRN BUFFER NPF is a specialized combination of non-volatile organic acids designed to eliminate the disadvantages associated with traditional acids like acetic acid.
The main issue with conventional acids is their tendency to evaporate (volatility) at high temperatures, causing fluctuations in the bath pH. CRN BUFFER NPF:
Stable pH Levels: Since it does not evaporate, it maintains a constant bath pH throughout high-temperature processes. This prevents shade deviations, especially in sensitive dyeings.
Odorless Working Environment: It lacks a sharp or irritating smell, preserving air quality within the facility and providing a user-friendly environment.
The product is used to safely lower the pH of the fabric following alkaline processes (bleaching, mercerization, caustification).
Deep Neutralization: Rapidly neutralizes alkaline residues trapped within the fiber core. This prevents yellowing of the fabric during drying and avoids quality loss in subsequent stages like dyeing or softening.
Buffering Power: It acts as more than just an acid; it provides buffering to stop the pH from shifting in unintended directions.
Zero Spotting Risk: Its pure and homogeneous structure ensures no acid spots or localized shade variations occur on the fabric.
Stainless Steel Friendly: It has a much lower corrosive effect on machinery compared to acetic acid, extending the equipment's lifespan.
Economical and Effective: Its concentrated and balanced formula provides powerful neutralization even at low dosages.
Broad Application Range: It serves as a primary acid source in the dyeing, washing, and neutralization baths for cotton, viscose, polyester, and their blends.
