2. 2 TEXTILCHEMIE DR. PETRY GMBH PERILITH ALS substrate/storage material for bleaching chemicals to create wash out effects on garments alternative to pumice stones PERILITH ALS

3. 3 TEXTILCHEMIE DR. PETRY GMBH PERILITH ALS Chemical basis: amorphous silicates Appearance: golden shining granulate, built up of many flexible layers

4. pumice stones TEXTILCHEMIE DR. PETRY GMBH PERILITH ALS

5. 5 TEXTILCHEMIE DR. PETRY GMBH PERILITH ALS Application: Pretreatment of PERILITH ALS PERILITH ALS is soaked for 10 – 20 min with a bleaching chemical such as - potassium permanganate solution - diluted sodium hypochlorite

6. 6 TEXTILCHEMIE 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

7. 7 TEXTILCHEMIE DR. PETRY GMBH PERILITH ALS Treatment of the fabric - the slightly damp fabric is treated with the soaked PERILITH ALS machine: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

8. 8 TEXTILCHEMIE DR. PETRY GMBH 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

9. 9 TEXTILCHEMIE DR. PETRY GMBH PERILITH ALS Treatment of Blue Denim with 40 g/l potassium permanganate ratio of fabric to storage material: 1:1 PERILITH ALS pumice stones basic fabric

10. 10 TEXTILCHEMIE DR. PETRY GMBH PERILITH ALS Differences to pumice stones: flexible, soft granulate  lower fibre abrasion  lower fibre damaging more uniform wash out effects
