Abstract
【解決手段】ポリ乳酸(PLA)繊維を含む不織布で構成されているため、生分解性に加えて、従来不要となったスクラップ繊維についても再溶融による再生が可能となる。特に、ポリ乳酸繊維と共重合ポリ乳酸繊維の混合比率を変更することにより、不織布製造中で、熱接着強度を調整することができ、また、混合する共重合ポリ乳酸繊維の融点を選択することにより、あらゆる包装機械のシーリング条件にも対応可能となる。ポリ乳酸と共重合ポリ乳酸については、それぞれの単相繊維のブレンドとしての使用の他、芯鞘の2成分形態の繊維としても使用できる。

Description
相対粘度: 3.50±0.25
%ダイマー: 12.0±1.00
最大黄色度指数: 35.0
最大残渣ラクチド: 0.30
これは、本発明の目的を達成するために満足できるものであった。
相対粘度: 4.00±0.1
%ダイマー: 1.40±0.2
最大黄色度指数: 30.0
最大残渣ラクチド: 0.30
この樹脂は、606Dより顕著な透明度を示した。これはダイマー含有量と黄色度指数の低下が原因であり、その相対粘度が上昇して、繊維製造中の延伸比率が上昇したからである。この結果、6060Dや他の標準的なPLA繊維の3.5〜4.0グラム/デニールに対して、糸剛性が4.7〜5.0グラム/デニールまで上昇した。
a. 18gsm(g/m2)(坪量)
(grams per square meter)
b. 21gsm
c. 25gsm
d. 28gsm
繊維製造の延伸比率が低下し、透明度の高い繊維が減少した.これは、非晶質度が上がり結晶度が下がったからである。結果として、透明な布地でらい、例えば茶葉等の中身が見える良い透明度(visibility)であった。

Ingeo(インジオ)(登録商標)PLAタイプ6400Dを選択して、ティーバッグに装着する紐用の連続フィラメント糸(continuous filament yarn)を作製した。糸は、一本のフィラメント当たり3デニールで、50本のフィラメントから形成された。糸は、空気撚糸して(air entangled)、テクスチャーされて(textured)、PLAティーバッグの紐が作られた。
