RC-639 is developed to help the decomposition of long and short-fiber interwoven fiber oil ester and its impurities, the aggregation of oil ester and its impurities, and the removal of other impurities and impurities.

Incomplete emulsification and scouring are not a single reason. The incomplete scouring or residual formation is mostly due to the incomplete chemical structure of the scouring agent itself, resulting in self-cracking, not because the fiber fabric contains a large number of impurities that cannot be removed.

According to the CNS12915 and L3233 standard testing procedures, no matter whether long-fiber nylon or other fibers are used when using RC-639 low foam acid and alkali-resistant emulsifying scouring agent for scouring, emulsification, and de-sizing, the decomposition and removal of emulsified oil and impurities The degree can reach more than 90%.

This agent RC-639 and RC-629 are similar products, but this agent has better penetration and can be used for specific needs.
