| 摘要 |
Polyethylene terephthalate fiber-containing fabric is flameproofed by application of an aqueous suspension of finely divided particles consisting essentially of octagonal hexabromide formed by the incomplete bromination of cis, trans, trans cyclododecatriene to provide a mixture having a melting point in the range of 177 DEG -191 DEG C. determined by differential scanning colorimetry using a heating rate of 10 DEG C. per minute. The treated fabric is dried and then heated with the octagonal hexabromide particles thereon to a temperature above the melting point of the mixture, but not in excess of about 200 DEG C. for a period long enough to achieve adequate penetration (30 seconds), to cause the hexabromide particles to diffuse into the fibers of the fabric to maximize fire resistance and obtain proper fixation of the particles to the fabric in a manner providing durability to laundering with minimum damage to the fabric.
