SARAFLAM-CWF

Saraflam-CWF | Flame Retardant for Cotton

Product Information

Saraflam-CWF is an organo phosphorous durable flame retardant for 100%

cellulosic fibres such as cotton and regenerated cellulosic fibres like viscose, modal, tencel. Saraflam-CWF chemically reacts with these fibres thereby imparting durable flame retardancy which can withstand several launderings and dry cleanings. Saraflam-CWF does not affect the drape of the fabric and does not leave any white residue on the fabric thus the minimum effect on the shade.

Saraflam-CWF can also be combined with other finishing agents. Saraflam-CWF prevents flame propagation in presence of fire. It is recommended for home textiles, industrial textiles, and apparels.

Application

Before finishing with Saraflam-CWF, please ensure that the fabric is free from residues of earlier treatment which could otherwise hamper the performance of Saraflam-CWF

  • Saraflam-CWF :  300-400 g/l
  • Saraprint AC : 70-100 g/l
  • Ammonium chloride : 7-10 g/l
  • Phosphoric acid 80% : 20-25 g/l
  • Sarawet NF : 2-5 g/l
  • Pick-up : 70-80% (2 dip-2 nip)
  • Drying : 120-130 deg.C
  • Curing  : 160 deg.C, 4-5 min.

Please ensure that the padding temperature does not exceed 30 deg.C

Note :
  • After finishing, the fabric has to be washed with 5-10 g/l soda ash (pH maintained at 9-10) along with 2-4 g/l Celldet-R to neutralise the phosphoric acid and unreacted Saraflam-CWF followed by rinsing in plain water twice or thrice.
  • Final pH of fabric should be 6.5-7 before drying.

  • Dry add-on of minimum 25-30% ensures required performance

  • Flame retardancy depends upon actual add-on of Saraflam-CWF on the finished fabric, therefore lab trials are recommended to arrive at required dosage

  • Many common finishes like silicone softeners, PE emulsions etc. may have a negative influence on flame retardancy, therefore prelab-trials are essential to assess the suitability of other softners

Saraflam-CWF is recommended for following test methods.

1.BS 3119 (1959) Vertical flame test

2.BS 5852 Cigarette bud test for upholstery

3.BS 5852 Part 1 (1979), BS 5651 (1978) for upholstery

4.ASTM D6413 has been adopted from Federal Test Standard No.191A method 5903.1

Precautions

Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C.Close lids firmly to avoid contact with air and moisture.

Shelf Life : 8 months from the date of manufacturing, if stored under controlled conditions.
