In the part 1 of this study, the flammability of the blended yarns was represented by the parallel model of the burning resistance (i. e., reverse of burning rate) of each single fibers.<BR>This paper describes the flame-retarded effects of the yarn finished with flame retardants (cotton finished with THPC, polyester finished with polyvinychloride) on the flammability properties of these multi plied yarns. The experiment was carried out by the direct ignition method, thermogravimetry and infrared spectral analysis and following conclusions were obtained.<BR>(1) The degree of self-extinction of multi plied yarns when exposed under an ignition source become maximum at the specific mixing ratio and the rating was in order of: both yarns finished>only polyester yarn finished>only cotton yarn finished.<BR>(2) General burning resistance of the multi plied yarns was represented by the series and parallel model of the burning resistance of each single yarn.<BR>(3) In the case of the burning of multi plied yarns composed of flame retardant finished yarn and unfinished yarns to the other unfinished yarn during pyrolysis and the flammability properties were decreased.<BR>(4) The burning resistance of the series part of the model was supposed to be the heat transfer reaction of the flame retardant from the finished yarn to the other unfinished yarn.
