PERILITH ALSPERILITH ALS
• Chemical basis: amorphous silicates
• Appearance: golden shining granulate, built up of many flexible layers

PERILITH ALS
Application:
• Pretreatment of PERILITH ALS
PERILITH ALS is soaked for 10 – 20 min with a bleaching chemicalsuch as
- potassium permanganate solution- diluted sodium hypochlorite
6TEXTILCHEMIE DR. PETRY GMBH
PERILITH ALS
• the excess of the bleaching liquor has to be removed by
• centrifuging
• tumbling for some minutes in a tumbler with an accompanying fabric
• dripping off
7TEXTILCHEMIE DR. PETRY GMBH
PERILITH ALS• Treatment of the fabric
- the slightly damp fabric is treated with the
soaked PERILITH ALSmachine: rotary drum
treatment time: 10 – 30 min
treatment temperature: 20°C
- complete the treatment (rinsing, removal of the residual bleaching agent, softening, etc.)
- separate PERILITH ALS and the fabric

PERILITH ALS
Achieved effects depend on
• ratio of PERILITH ALS to fabric
• concentration of the bleaching chemical
• construction and dyeing of the fabric
• treatment time
• machine conditions

Differences to pumice stones:
• flexible, soft granulate lower fibre abrasion lower fibre damaging
• more uniform wash out effects
