Orco Synthrowite RBP™ is an optical brightener developed for polyester and polyester/cotton blends yielding whites of outstanding brilliance of a neutral bluish tone and offering excellent light fastness. Orco Synthrowite RBP™ is applicable to polyvinylchloride, acetate, and triacetate fibers via high-temperature processes (beam, jet, and other circulating dyeing equipment) as well as pad-thermosol processes and is compatible with many finishing resins with thermosetting processes.
|Chemical Nature||Oxazole derivative|
|Appearance||Cream colored, fine aqueous dispersion|
|Solubility||Easily dispersible in water|
|Fastness on PES fiber||very good to light, sublimation and washing|
Use 0.35 – 1.5 % Orco Synthrowite RBP™ on weight of goods in high temperature equipment alone or with chlorite.
The use of Orco Dye Carrier LLRS-2™ is required when high-temperature equipment is not available.
Use 6.0-35.0 gms/liter of Orco Synthrowite RBP™ followed by drying and heat-setting (thermosol) at 338°-392°F (170° – 200°C) for 30 seconds.
Orco Synthrowite RBP™ is applicable to polyester/cotton in resin finishing baths with a subsequent thermosetting process at 330°F (165°C) for 45 – 60 seconds.
Orco Synthrowite RBP™ should be stirred before weighing out of the drum and should not be added directly to a hot bath.
