The invention discloses a pyrocondensation ratio testing method and a special device. The pyrocondensation ratio testing method comprises the following steps that testing persons cut down samples and use a printer to respectively print a mark on bag testing lining fabric samples, the distance of corresponding marks is L0, the marks and edges can keep a certain interval, and the lapping cloth samples to be tested is flatly spread in a specimen placer; the specimen placer is a ventilate net-shaped frame type frame form, the specimen placer is placed on a cloth guiding curtain, the cloth guiding curtain passes through a baking oven in an uniform speed, and the baking oven can keep a constant temperature; and after cooling, the distance of the longitude and latitude corresponding marks on the measuring samples is L1, and the pyrocondensation ratios of half-finished goods are accurate through calculating. The pyrocondensation ratio testing method and the special device provided by the invention can realize non-com
