SARAFLAM-DUR | Durable Flame Retardant

Product Information

Saraflam-DUR is an organo phosphorous durable flame retardant for 100% cellulosic fibres such as cotton and regeneratred cellulosic fibres like viscose,modal,tencel. Saraflam-DUR chemically reacts with these fibres thereby imparting durable flame retardency which can withstand several launderings and dry cleanings. Saraflam-DUR does not affect the drape of the fabric and does not leave any white residue on the fabric thus minimum effect on shade. 

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

 ----- - 

- After finishing, the fabric has to be washed with 10-20 g/l soda ash (pH maintained at 9-10) to neutralise phosphoric acid and unreacted Saraflam-DUR 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 retardency depends upon actual add-on of Saraflam-DUR on the finished fabric, therefore lab trials are recommended to arrive at required dosage

Saraflam-DUR is recommended for following test methods.
