194質量部のジメチルテレフタレート(DMT)、124質量部のエチレングリコールを反応容器に入れ、これにDMTに対し0.1モル%の酢酸亜鉛、および0.02モル%の三酸化アンチモンを添加して、窒素ガス雰囲気下3時間かけて150℃から230℃に昇温しつつエステル交換反応を行った。次いでこの生成物を重縮合缶に移し、DMTに対して2モル%の3,5−ジ(β−ヒドロキシエトキシカルボニル)ベンゼンスルホン酸テトラブチルホスホニウム塩を加えて、280℃、1mmHg以下の減圧下で5時間重縮合反応を行って共重合ポリエステル樹脂を得た。元素分析にて原子換算で1830ppmのリン、および1890ppmのイオウが検出された。この樹脂を原料として定法により2.2デシテックスの短繊維Cを作製した。
194質量部のジメチルテレフタレート(DMT)、124質量部のエチレングリコール、DMTに対して0.4モル%の前記化合物(r)のホスフィン酸化合物を反応容器に入れ、これにDMTに対し0.1モル%の酢酸亜鉛、および0.02モル%の三酸化アンチモンを添加して、窒素ガス雰囲気下2時間かけて150℃から230℃に昇温しつつエステル交換反応を行った。次いでこの生成物を重縮合缶に移し、280℃、1mmHg以下の減圧下で5時間重縮合反応を行って共重合ポリエステル樹脂を得た。元素分析にて原子換算で370ppmのリンが検出された。この樹脂を原料として定法により2.2デシテックスの短繊維Dを作製した。
1236質量部のテレフタル酸、62質量部の(2−カルボキシエチル)フェニルホスフィン酸[(2-Carboxyethyl)phenylphosphinic acid]と、1055質量部のエチレングリコールを反応容器に仕込み、さらに三酸化アンチモンを0.55質量部、トリエチルアミン11質量部を加えて230℃、ゲージ圧2.5kg/cm2 でエステル化に生成する水を逐次除去しながら2時間エステル化反応を行った。続いて1時間で系の温度を275℃まで昇温して、この間に系の圧力を徐々に減じて0.1mmHgとし、この条件下で2時間重縮合時間を行った。得られた共重合ポリエステル樹脂の〔η〕は0.64でリン含有量は5900ppmであった。この共重合ポリエステル樹脂を原料として常法により、紡糸、延伸して2.2デシテックスの短繊維Eを作製した。
表1に示した所定の質量混合比の繊維を混綿、カーディングして目付100g/m2の混繊ウェブを作製し、これに3MPaの高圧水を連続的に噴霧して油剤を除去した。これを乾燥後、針密度50本/cm2にてニードルパンチ処理を行い、摩擦帯電と交絡を同時に行って、帯電濾材試料を得た。ニードルパンチ処理時の温湿度は、27℃、55RH%とした。なお表1に示した上記A〜E以外の繊維は以下の通りである。
NC:宇部日東化成(株)製ポリプロピレン短繊維(2.2dtex,51mm)
707:東洋紡績(株)製標準ポリエステル繊維(2.2dtex,51mm)
K8:日本エクスラン工業(株)製アクリル繊維(2.2dtex,51mm)
圧力損失は、帯電濾材試料をダクト内に設置し、空気濾過速度が30cm/秒になるようコントロールし、濾材上流、下流の静圧差を圧力計で読み取り求めた。また粒子捕集効率(%)の評価は粒子径0.3μmのNaCl粒子を用い、30cm/秒にて行った。
JIS D 1201(1977)自動車車室内用有機資材の燃焼性試験方法に従って実施した。試験点数は、各濾材のカーディングのMD方向およびTD方向それぞれ5箇所ずつとした。
