Abstract
The present invention discloses novel halogenated flame retardant formulations that effectively flame retard textiles at low binder and/or the flame retardant synergist contents, novel modes of application thereof on textiles, and flame-retarded textile fibers and fabrics which are treated by these formulations.
Claims33
A halogenated flame retardant formulation comprising a carrier and a compound having the formula I
- wherein each of R1 and R2 is independently a straight or branched C1-C5 alkyl group,
- further wherein each X independently represents a halogen;
- k is 1 or 2;
- n is an integer between 1 and 5, inclusive;
- and m is an integer between 1 and 3, inclusive.
A flame retarded textile fabric, coated or exhausted by a halogenated compound having the formula I:
- wherein each of R1 and R2 is independently a straight or branched C1-C5 alkyl group,
- further wherein each X may independently represent a halogen;
- k is 1 or 2;
- n is an integer between 1 and 5, inclusive;
- m is an integer between 1 and 3, inclusive.
A halogenated flame retarded polyester fiber being free of a binding agent and/or free of a flame retardant synergist.
