PROBLEM TO BE SOLVED: To form a sliver with polyester fibers cut into a predetermined length dimension and form a cotton ball to constitute a cotton swab without ballooning costs.SOLUTION: The method includes: a heat treatment process for heat treating polyester fibers on which crimps are formed and which are cut into a form having a length of 40 mm or less for a predetermined time at a temperature where a crystallization occurs a static protection treatment process for carrying out a static protection treatment following the heat treatment process and a carding process for performing a carding treatment on polyester fibers which are subjected to a humidification treatment.COPYRIGHT: (C)2014,JPO&INPIT【課題】費用を嵩ませることなく、所定の長さ寸法に切断されたポリエステル繊維によりスライバーを形成させ、綿球を作成して綿棒を構成する。【解決手段】捲縮が形成されると共に40mm以下の長さに切断形成されたポリエステル繊維に所定時間に亘り結晶化が起きる温度で加熱処理を施す加熱処理工程と、上記加熱処理工程の後に静電気防止処理を施す静電気防止処理工程と、上記加湿処理が施されたポリエステル繊維にカード処理を施すカード工程とを備えたことを特徴とする。【選択図】図1
