Abstract
There is disclosed a method for manufacturing particle deposited body comprising supplying, under sucking condition, particles entrained by air on a continuous carrier sheet which is running at a prescribed direction to deposit the particles on the carrier sheet, thereby obtaining a particle deposited body comprising the particles and the carrier sheet, the carrier sheet having an air-permeability of 4.0 seconds/(300 ml·32 pcs.) or less.
Claims4
A method for manufacturing a particle deposited body, comprising:
- supplying a continuous carrier sheet which is running in a prescribed direction and having a tensile strength in the MD direction of 500 cN/25 mm or more;
- supplying a retaining sheet onto said carrier sheet;
- providing a partial vacuum behind said carrier sheet and retaining sheet so as to draw air therethrough in a thickness direction of the retaining sheet, said carrier sheet having an air-permeability of 4.0 seconds/(300 ml·32 pcs.) or less;
- entraining particles by air so as to deposit said particles into said retaining sheet to obtain a particle deposited body in which the particles are retained throughout the thickness direction of said retaining sheet.
