Abstract
By introducing an expanded structure into a rubber portion during heating under pressure at the time of integrating a mat, and by using as a backing of a carpet a foamed rubber sheet having an expansibility of 1.2 to 3 times and a skin layer having a thickness of 0.1 to 1.0 mm, the shrinkage of the mat by shrinking, washing and drying after heating under pressure can be relaxed, and the waving of the mat can be prevented effectively. At the same time, the mat of the invention has excellent fitness to a floor surface, light-weight, strength and heat resistance.
