RUCOFIN® SIQ NEW, the patented polymer modified internally quaternary silicone is, after millions of running metres, the star amongst the process-stable softeners in textile finishing. Hardly any other silicone softener combines hydrophilic softness with excellent application properties and highest process security in such a way. However, what does process security mean?
Silicone stains caused by a failed soft handle finish are one of the most unpleasant damaging events in finishing. Especially after thermal treatment, which may cause crosslinking reactions, these stains are often difficult to remove by scouring or cannot be removed at all.
The reasons for such damages are varied. A completely neglected topic in this connection still is the process security of silicone softeners. On one hand, the reasons are to be found in the chemistry of silicone polymers or the physics of emulsions manufactured thereof. On the other, they are caused by disturbing influences during finishing.
Specific chemical modifications and optimised formulations of RUCOFIN® SIQ NEW enable a distinctly improved process security during finishing and, additionally, a higher effect level.
