How to Treat Cellulosics with a Water Repellent
A recommended water-repellent treatment for acrylic involves the application of Orco Repel WZC™ which is a non-durable, economical wax emulsion water repellent containing a zirconium salt base, providing excellent water repellency on both synthetic and cellulose fibers.
- Fabrics to be treated should contain no residual surface active agents and have no higher pH than 7.0.
- Bath concentration for padding will vary depending on the fabric and weight but generally 2-5% owb is adequate for most purposes.
- Water temperature should be in the area of 50-100°F(10-38°C) before adding the Orco Repel WZC™. Higher temperatures sometimes cause insolubility.
- Treated fabrics should then be dried thoroughly at temperatures below 300°F(150°C) if possible.
