Ivory, natural, fabrics are processed with
the following:
- An amylase enzyme removes the sizing,
(wheat starch).
- Two detergents, one an anionic surfactant
and the other a fast wetting agent, clean the fabric.
- A defoamer controls the sudzing of the
detergents.
- A natural tallow oil softens the fabric
at the end of the finishing process.
White, bleached, fabrics are also treated with:
- Sodium silicate is a sequestering agent
and Ph stabilizer that aids the bleaching process.
- Caustic soda removes the natural wax from
the fabric (yarn, actually), and activates the peroxide.
- A non-ionic surfactant acts as a cleaning
agent and silicate dispersant.
- Bleach itself whitens the fabric.
