Description
(a)非弾性ポリエステルと該非弾性ポリエステルの融点より40℃以上低い融点を有する弾性熱可塑性エラストマーとが配された複合短繊維であって、該非弾性ポリエステルが複合短繊維表面の25〜49%を占めるように露出している複合短繊維と、
(b)単糸繊度が1〜7dtexの範囲内である、ポリトリメチレンテレフタレート系短繊維とから構成され、
その繊維交絡点の一部が可撓性熱固着点で熱固着されており、JIS K6401により測定された25%圧縮硬さが、11N以下である
ことを特徴とする、高弾性繊維球状体からなる成型品に関する。
本発明において、上記ポリトリメチレンテレフタレート系短繊維は、2種の成分がサイド・バイ・サイド型または偏心芯鞘型に接合された複合繊維であって、少なくとも一方成分がポリトリメチレンテレフタレートであり、潜在捲縮が発現してなるものが好ましい。また、成形品のJIS K6401の硬さ測定時に測定される直線性が40%以下であるものが好ましく、さらに、JIS L0217−103法に規定された洗濯を3回行った後において、JIS K6401による厚みの変化に準拠して測定された歪が5%以下であるものが好ましい。
この成型品は、クッションまたは詰め物または中綿として好適に使用される。
本発明の(a)複合短繊維に用いられる非弾性ポリエステルとは、ポリエステルであって非弾性のポリマーであればいかなるものでもよいが、通常のポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリヘキサメチレンテレフタレート、ポリテトラメチレンテレフタレート、ポリトリメチレンテレフタレート、ポリ−1,4−ジメチルシクロヘキサンテレフタレート、ポリピバロラクトンまたはこれらの共重合体エステルからなるポリマーが挙げられ、繰り返し歪みがかかる用途には、歪みの残しにくいポリブチレンテレフタレートが好ましい。特に、複合繊維の融着成分に用いられるエラストマーのハードセグメントがポリブチレンテレフタレートの場合は、特に剥離などの問題がなく良好である。
なお、ポリウレタン系エラストマーやポリエステル系エラストマーなどの弾性熱可塑性エラストマー中には、各種安定剤、紫外線吸収剤、増粘分枝剤、艶消剤、着色剤、その他各種の改良剤なども必要に応じて配合されていてもよい。
また、この2つのポリマーの断面での厚い部分の肉厚比(図1に示す、複合短繊維の芯成分の非弾性ポリエステルの最大厚み(LP)と弾性熱可塑性エラストマーの最大厚み(LE)の比率LP/LE)は、1.2〜3.0の範囲が好ましい。肉厚比のさらに好ましい値は、1.5〜2.9である。この肉厚比が1に近くなると捲縮の発現が小さくなったり、熱処理での捲縮発現が少なくなり、同様に繊維が球状化しにくくなり、非弾性捲縮短繊維を巻き込みながらの融着が起きにくく好ましくない。一方、この肉厚比が大きすぎると、捲縮が大きくなり過ぎたり、熱処理での捲縮も極端に起きやすく嵩などが小さくなったり、風合いにゴロゴロ感が出て好ましくない。
本発明で用いられるポリトリメチレンテレフタレート系短繊維とは、トリメチレンテレフタレート単位を主たる繰り返し単位とするポリエステル短繊維を言い、トリメチレンテレフタレート単位が約50%以上、好ましくは70モル%以上、さらに好ましくは80モル%以上、特に好ましくは90モル%以上のものをいう。従って、第3成分としての他の酸成分および/またはグリコール成分の合計量が約50モル%以下、好ましくは30モル%以下、さらに好ましくは20モル%以下、特に好ましくは10モル%以下の範囲で含有されたポリトリメチレンテレフタレートを含有する。
このような潜在捲縮発現性ポリトリメチレンテレフタレート系短繊維としては、例えば、下記(1)〜(2)が挙げられる
ここで、歪は、JIS K6401による厚みの変化を測定するものとする。
捲縮数、捲縮度
JIS L1015により測定した。
25%、50%圧縮硬さ
試作された繊維球状体を直方体30cm×30cm、1g/cm2の荷重で計測して厚み5cmになるように側地に詰め、JIS K6401による25%あるいは50%圧縮硬さを測定する方法を流用して求めた。
直線性
図3参照
洗濯後の厚み歪み
JIS K6401に準拠した。
なお、洗濯後の乾燥は、自然乾燥により20時間放置した。
テレフタル酸とイソフタル酸とを80/20(モル%)で混合した酸成分とブチレングリコールとを重合し、得られたポリブチレン系テレフタレート40%(重量%)をさらにポリテトラメチレングリコール(分子量2,000)60%(重量%)と加熱反応させ、ブロック共重合ポリエーテルポリエステルエラストマーを得た。この熱可塑性エラストマーの融点は157℃であった。この熱可塑性エラストマーをシースに、常法で得られたポリブチレンテレフタレート(融点224℃)をコアに、シース/コアの重量比で50/50になるように特殊口金とポリマー吐出配分を調整して複合短繊維を得た。この繊維を2.0倍に延伸したのち、ポリエチレンテレフタレートとポリエチレンオキシドのセグメント化ポリマーのエマルジョンを付与し120℃で乾燥固化捲縮発現し、51mmに切断した。ここで得られた複合短繊維の繊度は3.3dtex、捲縮数は10個/インチ、捲縮度は15%であった。
次に、異方冷却により立体捲縮を付与した、ポリトリメチレンテレフタレートからなる短繊維を得た。この短繊維は、繊度が6.6dtex、繊維長が64mm、捲縮数が11個/インチ、捲縮度が26%であった。
ball)を得た。この繊維球状体を顕微鏡で観察したところ、球状体表面にはポリメチレンテレフタレート系短繊維が90重量%の以上の確率で観察された。しかも、側地の中に吹き込む吹き込み機にて、クッションが和知あに吹き込んでみたが、吹き込みのトラブルがなく良好で、得られたクッションの感触もソフトで弾力性がよかった。
次いで、この繊維球状体をブロック状の通気金型に詰め込み、190℃で10分間、熱成形して得られた成形品について、評価した。結果を表1に示す。
(a)複合短繊維とポリトリメチレンテレフタレート系短繊維(もしくはポリエチレンテレフタレート短繊維)の種類や割合を変更する以外は、実施例1と同様にして実施した。結果を表1に示す。
(a)複合短繊維を用い、あるいは用いず、これに、ポリメチレンテレフタレート系短繊維あるいはポリエチレンテレフタレート短繊維を用いて、カードウェブを作製し、評価した。結果を表1に示す。
