A method for the manufacture of a cushioning material comprising the steps of compressing three-dimensionally crimped short synthetic filaments to form a shaped mass of filaments, applying an adhesive agent to the resultant shaped mass of filaments, then heating the shaped mass thereby drying the adhesive agent adhering to said short filaments and uniting adjacent filaments at the points of their mutual contact, and pressing the resultant crude cushioning material in the presence of steam thereby compressing the crude cushioning material. |
