PROBLEM TO BE SOLVED: To improve the soiling resistance, light fastness and washing resistance and the like by forming the pile yarn of colored nylon obtained by coloring nylon 6 whose amino group unit is less than a specified value by a solution dyeing method in a mat for rent formed of a foundation cloth, pile yarn and a backing layer. SOLUTION: The mat is formed of a foundation cloth, pile yarn and a backing layer. As the foundation cloth, a polyester fabric is preferred because the mat is a dust controlling type that is required to be heat resistant and dimensionally stable. Nylon used for the pile yarn is nylon 6, the amino group unit existing in the nylon is 20 7μeq (a micro equivalent), preferably 12 to 18μeq/g. The pile yarn is obtained by twisting nylon and nylon filaments colored with a disperse dye by a solution dyeing method. In addition, as the backing layer, a nitryl/butadiene rubber is suitable from the point of durability.
