(発明の要旨)
本発明の目的は、早期の不活性化を防止するために除去可能な物質(例えば、被包剤)で活性粒子を不活性化することによって、達成される。活性粒子に対して、または活性粒子と共に使用される、除去可能な物質は、活性粒子の孔を塞ぐか、または阻害することによって、活性粒子を不活性化する。除去可能な物質は、活性粒子の吸収能力を無効にするか、または減少させるが、この吸収能力の消失は永続的ではない。従って、除去可能な物質が活性粒子から除去される場合、その吸収能力は増大または回復する。言い換えると、除去可能な物質の除去により、活性粒子の再活性化または再生が生じる。
活性粒子は、孔またはトラップを有し、固相、液相、および/または気相、ならびにそれらの組み合わせの物質を吸収する能力を有する粒子である。これらの孔は、サイズ、形状、および質が、活性粒子の型に依存して変動し得る。例えば、いくつかの粒子は天然に孔を有し(例えば、火山岩)、他の粒子(例えば、炭素)は、孔を作製するために、極温および活性化薬剤(例えば、酸素)で処理され得る。
この実施例は、性能増強合成糸を、図3のプロセスに従って製造したことを示す。より具体的には、この実施例は、活性炭を被包化し、それをポリエステル製基礎材料と混合してマスターバッチチップを形成し、そのマスターバッチチップを押出し成形して所望の糸を製造し、そして、曝露された活性炭粒子から保護的被包層を除去する方法を、実施したことを示す。この実施例から得られた糸は、ポリエステル製基礎材料に関連する物理的特徴を示すことに加えて、実質的な吸収能力を示した。従って、この糸は、ポリエステルの持ち味を有していたが、活性炭から与えられる性能増強品質(例えば、臭気吸収)も有していた。
実施例1に示したものと類似の手順を繰り返したが、異なる被包剤を使用して、異なるマスターバッチを作製した。この実施例の結果が、図7に示される。この実施例で使用したマスターバッチは、実施例1で使用したものと同じ分類のSA−30炭素を使用し、Textile Wax WとしてBASF(Charlotte,North Carolina)により販売されている被包剤ワックス層を使用した。
