METHOD FOR INCREASING THICKNESS OF NON-WOVEN FABRIC AND APPARATUS FOR IMPLEMENTING THE SAME |
摘要 |
<p>The present invention utilizes jet streams of hot gas at a high efficiency and thereby to increase a bulk of non-woven fabric. Non-woven fabric containing thermoplastic synthetic fibers 20 is subjected to jet streams of hot gas 12 in a thickness direction of the non-woven fabric. A temperature of the jet streams of hot gas 12 used for this process is set to a level lower than the temperature at which a resinous ingredient forming the surface of the thermoplastic begins to be melted. The jet streams of hot gas 12 are directed to penetrate fiber interstices in the non-woven fabric and then to strike on a means 15 serving to divert the jet streams of hot gas.</p> |
