- Abstract
The flame resistance of wool fabrics is greatly enhanced by reaction with halogenated organic acid anhydrides in dimethylformamide at 50C. Chlorendic, chloroacetic, dichloroacetic, dichloromaleic, tetrachlorophthalic, bromoacetic and tetrabromophthalic anhydrides at low weight add-ons give fabrics that char in contact with flame but are self-extinguishing when the flame Is removed. Evaluation of several fabric types shows that even loosely knit fabrics are flame resistant. Fabric strength and handle are practically unchanged. The flame resistance of treated fabrics is unimpaired by laundering and drycleaning. Chlorendic anhydride appears especially promising because it is cheap and effective at low weight add-ons.
