Whitfield, Robert E. published the artcileFlame-resistant wool. IV. Chemical modification of wool with haloorganic acid halides, Application of 2,3-Dibromopropionylchloride, the publication is Textile Research Journal (1972), 42(9), 533-5, database is CAplus.
The flame resistance of wool fabrics was increased by treatment with aliphatic haloorganic acid halides, e.g. trichloroacetyl chloride [76-02-8] and 2-bromopropionyl bromide [563-76-8], in DMF for 15-30 min at 50°; both Cl and Br derivatives were effective. At least 2% combined halogen was necessary to protect woolen fabrics. The flame resistance was durable to drycleaning and laundering. Prior stabilization of the fabric to felting shrinkage was needed to evaluate durability of flame resistance to laundering.
