[9]記載の獣毛から得られた加工物。
本発明の改質方法で改質する獣毛としては、原料として天然ケラチンを含む動物性繊維を原料として用いることが好適である。獣毛としては、例えば羊毛、山羊毛、兎毛、アルパカ毛等を挙げることができる。またその繊維形態は毛、糸、編物、織物等を挙げることができる。
本発明では、獣毛を中性または弱アルカリ性の条件下に還元剤を含む還元処理液で処理をする。中性または弱アルカリ性とは、pHでいうと、pH7〜9であるが、必ずしもこれにこだわらない。従って、少し酸性域(具体的には、pH6〜7の間領域)からpH9を超えるアルカリ性域になっても構わないが、主としてpH7〜9の領域内で処理が行なわれる。pHは緩衝剤により調整することが好適である。
上記還元処理工程で得られた獣毛は、次に酵素処理工程に掛ける。酵素処理工程は、還元処理した獣毛を水溶性タンパク質およびトランスグルタミナーゼを含有する酵素処理液(水溶液)で処理する。
山羊毛改質処理でpH条件を中性にした場合において、ピリング効果に与える影響を検討した。
JIS L 1076 A法に従い、ICI型試験機を用いて評価した。試験結果を表1に示す。
本明細書中で、「風合い」は繊維や織物、編物に触れた手触りや肌触りの感触を、人の官能による感覚で表現する主観的評価である。実施例で行った風合いの評価は、未加工布地との相対評価により実施した。やわらかさ、あたたかみ、ふくらみ、ヌメリ感について、官能評価を行い、いずれも結果は良好だった。
やわらかさ、あたたかみ、ふくらみ、ヌメリ感について、官能評価を行い、いずれも結果は良好だった。
山羊毛について、実施例1のpH条件を弱アルカリ性にした場合において、その製造された山羊毛処理物へのピリング効果に与える影響を検討した。
やわらかさ、あたたかみ、ふくらみ、ヌメリ感について、官能評価を行い、いずれも結果は良好だった。
山羊毛100%の編地に対し、実施例1の還元処理における条件をpH5とすること以外は、実施例1と同様に改質処理を行い、編地を得、それについて実施例1と同様に抗ピリング性の評価を行った。還元処理を弱酸性pH条件下で行う事で、ピリング級数は2.5級となった。
山羊毛100%の編地の重量に対し浴比1:30の分解酵素処理溶液を用いた。分解酵素処理溶液は分解酵素としてビオプラーゼAPL−30(ナガセケムテックス社製)を0.59%owfとpH8リン酸ナトリウムバッファー2g/Lを溶解して調製した。横振り振盪機を用いカシミヤを44℃、40分間振盪して分解酵素処理を行った。
山羊毛100%の編地に対し、実施例1のゼラチンを小麦タンパク質とし、トランスグルタミナーゼ処理のみの加工を行った。この処理ではピリング級数が1.5級となり、抗ピリング性は向上しなかった。
