Abstract
Description
ASTM F1959/F1959M-06ae1 (Standard Test Method for Determining the Arc Rating of Materials for Clothing)に基づいたアーク試験(以下、単に「アーク試験」と記す。)に従い、目付(oz/yd2)及びATPV(cal/cm2)を求めた。これらの値から、単位目付あたりのATPVである比ATPV((cal・yd2)/(cm2・oz))を算出した。
アクリロニトリル50重量%と塩化ビニリデン49重量%およびスチレンスルホン酸ナトリウムからなる共重合体に共重合体の樹脂重量に対し三酸化アンチモン10重量%を添加したアクリル系繊維(表中「AF1」で示す。)、アクリロニトリル50重量%と塩化ビニリデン49重量%およびスチレンスルホン酸ナトリウムからなる共重合体に共重合体の樹脂重量に対し三酸化アンチモン25重量%を添加したアクリル系繊維(表中「AF2」で示す。)、ナイロン66(表中「NY」で示す。)、木綿(表中「Cot」で示す。)、難燃レーヨン(セテリ オサケュスティオ社製Visil(登録商標)、表中「Vis」で示す。レンチング社製LenzingFR(登録商標)、表中「LFR」で示す。)、パラ系アラミド繊維(帝人社製トワロン(登録商標)、表中「Twa」で示す。)、ポリエチレンテレフタレート(表中「PET」で示す。)を表1から5に示した原綿構成で混合し、通常の紡績方法で紡績及び撚糸し、紡績糸を得た。それぞれの紡績糸を使用して布帛を作製した。
製造例1から4で作製した布帛についてアーク試験を実施した。結果を表1に示した。使用したアクリル系繊維中の酸化アンチモン量がアクリル系繊維の樹脂重量に対し8重量%以上であるAF1(三酸化アンチモン平均含有量10重量%)及びAF2(三酸化アンチモン平均含有量25重量%)を使用した実施例1から4(製造例1から4)では比ATPVが1.3以上を達成した。より目付の小さい布帛で高い耐アーク性を得ようとするときにどのようなアクリル系繊維を使用すべきかは先行技術に十分な開示がなく、本発明により明らかとなった。
製造例1、5及び6で作製した布帛についてアーク試験を実施した。結果を表2に示した。使用したセルロース系繊維が天然セルロース系繊維である木綿を使用した実施例1(製造例1)では比ATPV 1.3以上を達成したが、難燃レーヨンを使用した比較例1(製造例5)及び比較例2(製造例6)では比ATPVが1.3に満たなかった。米国公開US2006/0292953号公報(特許文献2)では難燃化処理された綿を使用しうることが記載されていたが、より目付の小さい布帛で高い耐アーク性を得るためには、綿を難燃化する必要はなく、むしろ難燃化されていない天然セルロース系繊維を使用する必要があることが示された。
製造例1、3、7及び8で作製した布帛についてアーク試験を実施した。結果を表3に示した。実施例3(製造例3)と比較例3(製造例7)及び、実施例1(製造例1)と比較例4(製造例8)を比較したときにナイロン繊維を含まないと比ATPVが1.3に満たず、また、ナイロン繊維の添加量を増やしても比ATPVが下がる傾向にあった。米国公開US2006/0292953号公報(特許文献2)では約25重量%以下のナイロンを使用することが記載されていたが、より目付の小さい布帛で高い耐アーク性を得るためには、5~15重量%のナイロン繊維を使用する必要があることが示された。
製造例1及び9で作製した布帛についてアーク試験を実施した。結果を表4に示した。実施例1(製造例1)のナイロン繊維をPET繊維に置き換えた比較例5(製造例9)では比ATPVが1.3に満たなかった。
製造例1ないし4及び10で作製した布帛についてアーク試験を実施した。結果を表5に示した。パラ系アラミド繊維を添加しなかった比較例6(製造例10)では測定時に生地が破れ、十分な耐アーク性が得られなかった。その一方で、実施例2(製造例2)と実施例4(製造例4)の比較、及び、実施例1(製造例1)と実施例3(製造例3)の比較からパラ系アラミド繊維の含量を5重量%から10重量%に上げても比ATPVが下がる傾向にあった。
これまでの製造例の中で最も高い比ATPVを示した製造例2の原綿構成を用いて目付を5.2 oz/yd2から5.6 oz/yd2に増やした布帛を製造例11で製造した。この布帛についてアーク試験を実施した。結果を表6に示した。実施例5(製造例11)に示したこの布帛はATPV 8.9 cal/cm2を達成した。
