Description
即ち、本発明は、以下の(1)〜(2)の構成を有するものである。
(1)熱可塑性樹脂に有機系吸湿性微粒子を1〜20重量%配合した繊維であって、繊維の20℃×40%RH条件下での吸湿率と30℃×90%RH条件下での吸湿率の差が4.0%以上であること、繊維強度が1.5〜10cN/dtexであること、熱可塑性樹脂がポリアミドまたはポリエステルであること、及び有機系吸湿性微粒子がポリアクリル酸塩架橋体であることを特徴とする吸湿性繊維。
(2)(1)に記載の吸湿性繊維を1重量%以上含むことを特徴とする繊維構造体。
試料繊維5gを石油エーテル100mlで洗浄した後、絶乾状態での重量W1(g)を測定する。20℃×40%RH及び30℃×90%RHの各々の雰囲気下で24時間放置した後の重量W2(g)を測定し、下記式によって、吸湿率を求める。
吸湿率(%)={(W2−W1)/W1}×100
吸湿率差(%)=|(30℃×90%RHの吸湿率(%))−(20℃×40%RHの吸湿率(%))|
吸湿性繊維の重量を測定して繊維の繊度を求めた後、引張速度=200mm/分とし、JIS−L1013に示される条件で5回測定し、荷重−伸長曲線を求めた。次に破断時の荷重値を初期の繊度で割り、繊維強度を求めた。
アクリロニトリル450部、アクリル酸メチル40部、p−スチレンスルホン酸ソーダ16部及び水118部をオートクレーブに仕込み、重合開始剤としてジーter−ブチルパーオキサイドを単量体全量に対して0.5%添加した後、密閉し、次いで攪拌下において150℃の温度にて20分間重合せしめ、平均粒子径2μm(光散乱光度計で測定)の原料微粒子の水分散体を得た。この水分散体に浴中濃度が35%になるようにヒドラジンを加え、102℃で2.5時間架橋処理を行い、続いて浴中濃度が10%となるようにNaOHを加え、102℃で5時間の加水分解処理を行った後、流水中で透析、脱塩、乾燥後、有機系吸湿性微粒子を得た。有機系吸湿性微粒子の窒素増加量は3.3%、塩型カルボキシル基4.3mmol/g、65%RHでの吸湿率は55%、平均粒子径は2μmであった。有機系吸湿性微粒子を70℃で12時間真空乾燥後、65%RH(20℃)のデシケーターに10分間放置後の吸湿率は10%であり、24時間後は55%であった。90%RH(20℃)のデシケーター24時間後の吸湿率は104%であり、該有機微粒子を20℃×40%RHのデシケーターに1時間放置した後の吸湿率は35%であり、吸放湿性が確認された。
Claims (2)
- 熱可塑性樹脂に有機系吸湿性微粒子を1〜20重量%配合した繊維であって、繊維の20℃×40%RH条件下での吸湿率と30℃×90%RH条件下での吸湿率の差が4.0%以上であること、繊維強度が1.5〜10cN/dtexであること、熱可塑性樹脂がポリアミドまたはポリエステルであること、及び有機系吸湿性微粒子がポリアクリル酸塩架橋体であることを特徴とする吸湿性繊維。
- 請求項1に記載の吸湿性繊維を1重量%以上含むことを特徴とする繊維構造体。
