    Abstract: PURPOSE:To eliminate the accumulation of a granule on a sheet like body, and to execute a sand blasting with good efficiency by executing the sand blasting in the state of the width direction of the sheet like body being kept vertically almost. CONSTITUTION:A slit like inlet port 5 in the vertical direction, the projection device of a granular body, and a slit like outlet port in the vertical direction, are provided on a sand blasting device 6, and the granular body is projected toward this sheet like body 1 while travelling a long sized sheet like body 1 toward the outlet port from this inlet port 5 with its being made vertical lengthwise. Consequently, the granular body collided with the sheet like body 1 can almost be dropped without remaining on the surface of the sheet like body 1.

    Abstract: PURPOSE:To impart excellent feeling having abundant repulsion to polyester- based fiber cloth by nipping both sides of the polyester-based fiber cloth and subjecting to heat treatment at a specific range of pressure, temperature and time in a state of not-generating any dimensional variation during the treatment. CONSTITUTION:Cloth made by polyester-based fiber or raw yarn of the polyester-based fiber is subjected to a swelling treatment using at least a species of dichloromethane, dibromomethane and bromochloromethane, or to at least a species of mellowing processing such as blowing, milling, beating or shrinking by compression. Next, both sides of the cloth is nipped between two belts of a roller belt-type heat-treating machine and 5-500g/cm pressure is applied, then subjected to heat treatment at a temperature of 150-200 deg.C for >=1sec in a state of not-generating any dimensional variation of the cloth during the heat treatment.
