<p>New wool filter for dust-proof mask is disclosed, in which wool fibers are mixed with chemical resin film slitting yarns so as to manufacture a non-woven fabric, thereby doubling the electrostatic force to improve the dust filtering function. In manufacturing the wool filter for a dust-proof mask, 40 to 90 weight % of wool yarns is uniformly mixed with 10 to 60 weight % of chemical resin film slitting yarns, preferably polyolefinic resin film slitting yarns. The wool filter does not include any chemical. According to the wool filter, the inhaling and exhaling resistance is lowered, and the dust capturing efficiency is greatly improved, while the filter is beneficent for the health of the wearer. The wool filter for a dust-proof mask can be used at a dust prevailing places. <IMAGE></p> |
