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

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
