Definitions
- texture and hue are important factors in judging product value.
- the texture of animal fibers is expressed as “soft”, “smooth” or “smooth”, and the texture is best when the fibers are collected and not subjected to chemical treatment other than refining. It is said.
- the hue is dyed according to the purpose, but when a clear hue from white or ultra-light to light is required, it is necessary to bleach the fiber prior to dyeing. Therefore, conventionally, oxidative bleaching using hydrogen peroxide and reductive bleaching using hydrosulfite or sodium bisulfite have been performed. However, these bleaching processes require heating for a long time and an alkali agent, which damages the fibers and causes the unique texture such as softness and slime feeling of animal fibers.

In the obtained spectrum, a peak attributed to sulfonic acid is obtained at 1040 cm ⁇ 1 . This sulfonic acid is derived from cystine contained in the fiber. When cystine is excessively oxidized, it is cleaved and converted into sulfonic acid. Therefore, the lower peak at 1040 cm ⁇ 1 indicates that the sulfonic acid content is low, indicating that excessive oxidation of the fiber due to the bleaching step is suppressed.

It was.
- FIG. 5 shows fiber cotton photographs before and after methylene blue staining in Example 21 and Comparative Examples 11-12. Since the undamaged fiber is colored light blue and the damaged fiber is colored deep blue, the fiber damage degree can be evaluated by the coloring concentration. As can be seen from FIG. 5, Comparative Examples 11 to 12 were clearly darker than untreated. Example 21 was colored lighter than Comparative Examples 11-12. From this, it was shown that Example 21 was suppressing the fiber damage by bleaching also in the evaluation by a methylene blue dyeing method similarly to the alkali solubility method. Therefore, it was shown that hydrolyzed keratin is effective in suppressing fiber damage among hydrolyzed proteins.

本発明において、漂白処理は、動物繊維の白度を向上させるために行われる処理であり、例えば、過酸化水素と界面活性剤を含有する水溶液、過酸化水素と珪酸ナトリウムとを含有する水溶液等を用いて行なわれる。また、染色処理は、特に限定されるものでなく、液流法、ジッカー法、ビーム法、コールドパッドバッチ法、パッドスチーム法、パッドロール法、連続法等を用いることができ、動物繊維の種類に応じて用いる染料及び染色方法を適宜選定すればよい。
斯かる加水分解ケラチンの分子量は、繊維への収着、浸透性の点から、ゲル濾過分析により測定される数平均分子量が、好ましくは10,000以下、より好ましくは8,000以下、より好ましくは5,000以下、より好ましくは3,000以下、より好ましくは2,000以下であり、且つ好ましくは130以上、より好ましくは150以上、より好ましくは200以上、より好ましくは300以上である。また、好ましくは10,000~130、より好ましくは8,000~130、より好ましくは5,000~130、より好ましくは3,000~150、より好ましくは2,000~200、より好ましくは2,000~300である。
アルカリ加水分解は、例えば水酸化ナトリウム、水酸化カリウム等のアルカリ金属水酸化物、水酸化カルシウム等のアルカリ土類金属水酸化物、アンモニア等のアルカリを用いることができ、通常0.1~0.8mol/L、好ましくは0.2~0.5mol/Lの濃度で、通常20~120℃、好ましくは0.1~72時間、ケラチン含有原料を処理するのが好ましい。
当該加水分解ケラチン溶液中には、その効果を損なわない範囲で、キレート剤、金属塩、セラミド、脂肪酸エステルなどの脂質成分、クエン酸、アスコルビン酸などの有機酸、非イオン界面活性剤、カチオン界面活性剤、両性界面活性剤、高級アルコール類、低級アルコール類、動植物油、シリコーン油類、天然多糖類、動植物抽出物、動植物由来の加水分解物及びその誘導体、pH調整剤、防腐剤等種々のものを適宜配合することができる。
したがって、動物繊維の漂白及び/又は染色処理において、当該繊維を加水分解ケラチン溶液に浸漬する工程を含む方法は、漂白及び/又は染色処理における当該繊維の損傷抑制方法となり得る。また、動物繊維の漂白及び/又は染色処理の前若しくは後又は前後に、当該繊維を加水分解ケラチン溶液に浸漬する工程を含む方法は、当該繊維の損傷を抑制する加工方法となり得る。
斯かる動物繊維の損傷抑制方法及び動物繊維の加工方法は、動物繊維を漂白及び/又は染色処理から保護し、当該繊維の風合いを保持するため、或いは耐光性保持のために有用である。
尚、本発明において、「風合い」とは、手触りや肌ざわり、着心地など、人がものに触れた時に感じる材質感を意味し、動物繊維が持つ独特な風合いとは、「柔らかさ」、「滑らかさ」、「ヌメリ」、「しなやかさ」、「ソフトさ」、「腰」、「ふくらみ」等を意味する。
また、耐光性とは、光による劣化(繊維の黄変や退色)に対する抵抗性を意味する。
<評価方法>
1.染色(耐光)堅牢度試験法
JIS L 0842 第3露光法に準じて繊維の染色(耐光)堅牢度を測定した。この試験により得られた等級が高い方がより堅牢度が高いことを示している。
JIS L 1081アルカリ溶解度法に準じて繊維のアルカリ溶解度を測定した。この試験により得られた値が小さい方が繊維の損傷が少ないことを示している。
JIS L 1081着色法(メチレンブルー法)に準じて繊維の損傷度を判定した。無損傷繊維はうす青に、損傷繊維は深い青に着色することから着色濃度によって損傷度を判定する。
繊維のATR-FTIRスペクトルをUniversal ATR Sampling Accessoryを付属したパーキンエルマー社製、PerkinElmer Spectrum One FTIR spectrophotometerを用いて記録した。積算回数16回、分解能4cm-1、4000~400cm-1の条件で行った。得られたスペクトルの内、1040cm-1にスルホン酸に帰属したピークが得られる。このスルホン酸は繊維に含まれるシスチンに由来し、シスチンが過剰に酸化されることにより、開裂し、スルホン酸に変化する。そのため、1040cm-1のピークが低い方が、スルホン酸の含有量が少ないことを示し、漂白工程による繊維の過剰酸化が抑えられていることを示している。
JIS L 1095 一般紡績糸試験法に準じて単糸引張強さ及び伸び率を測定した。
検体のパネラー評価を行った。業務でカシミヤ繊維を評価する機会の多い25人のパネラーが検体を自由に触り、手触り感について下記の基準で評価し、平均値を求めた。評価基準
