NOVELTY - The utility model relates to fabric testing technology field, and claims a heat preservation performance testing machine of warm-keeping cashmere fabric, comprising a detecting box body and an upper pressing frame, the inner part of the detecting box body is connected with a test table, the middle part of the test table is provided with a groove, the inner part of the groove is fixedly installed with a heating plate, the inner part of the groove is fixedly provided with a lower pressing frame located at the outer side of the heating plate. The utility model firstly pulls the lifting column upwards, so that the lifting column pulls the first spring to make it have elastic force, at the same time, controlling the upper pressing frame to move out of the groove, then paving the graphene cashmere fabric on the heating plate, the corner is put on the lower pressing frame, then loosening the lifting column, using the first spring with elastic force to pull the lifting column retracted in the shrinking opening, and the upper pressing frame presses the graphene cashmere fabric downwards, matched with the lower pressing frame to fix the graphene of the insulating cashmere fabric, preventing it from moving when it is blown by wind.
