Definitions
- the present invention relates to a fiber treatment agent for imparting water resistance, heat resistance and thermal shape memory ability to naturally derived fibers used in headdress products such as wigs and extensions.
- Naturally-derived fibers include wigs, extensions, and other headdress products as an example of their use, and unlike synthetic fibers, they have a natural texture and appearance that come from natural materials.
- regenerated protein fibers for example, regenerated collagen fibers, are obtained by solubilizing acid-soluble collagen or insoluble collagen with an alkali or an enzyme to obtain a spinning stock solution, which is then discharged into a coagulation bath through a spinning nozzle to be fiberized. Is done.
- regenerated collagen fibers generally have a higher water absorption rate because they are more hydrophilic than synthetic fibers, and their mechanical strength is extremely low when they contain a large amount of water. For this reason, the mechanical strength is significantly reduced due to the high water absorption rate during shampooing, and the product is broken when dried by a hair dryer thereafter, leading to a decrease in suitability as a hair ornament product.
- the regenerated collagen fiber also has a problem of low heat resistance, and when set at a high temperature similar to human hair in a set using a curling iron, shrinkage and crimping occur and the appearance is impaired. It ends up.
- the shape at the time of heat setting with a hair iron or the like continues to be memorized even after the subsequent hair washing (has thermal shape memorization ability), whereas with regenerated collagen fiber, at the time of heat setting with a hair iron or the like. Since the shape is lost in the subsequent hair washing (there is no thermal shape memory ability), there is a part that is inferior in terms of styling freedom as compared with the conventional plastic synthetic fiber.
- Patent Document 3 a method of allowing a compound having a methylol group to act on human hair fibers that originally do not have thermal shape memory ability in order to newly impart thermal shape memory ability.

Not only can it be imparted, but surprisingly, it has been found that the elasticity (tenacity) of naturally derived fibers can be improved from that before treatment and can be increased to a level close to that of human hair, and the invention was completed.
- a compound having a methylol group as used in References 1 to 3 crosslinks the tissue, so that the treated structure becomes brittle.
- the specific methylol compound it is common sense. It is surprising that when naturally-derived fibers were treated, the results showed that the elasticity (toughness) was improved as compared with that before the treatment.

すなわち、本発明の繊維処理剤中における成分(B)に由来する構成要素の含有量は、処理後の繊維により高い形状持続性と強度を付与する観点及び繊維表面の感触を向上させる観点から、繊維処理剤の全組成を基準として、好ましくは0.1~80質量%、より好ましくは1~60質量%、更に好ましくは1.5~50質量%、更により好ましくは3~40質量%、更により好ましくは5~30質量%、更により好ましくは5~25質量%、更により好ましくは5~20質量%である。
なお、本明細書において、「成分(B)に由来する構成要素」とは、1剤式の場合、前記縮合物のうち成分(B)に由来する構成部分と残存する成分(B)をいい、多剤式の場合、成分(B)自体をいうものとする。また、茶抽出物等のカテキン類を含む混合物等、成分(B)を含む混合物を用いる場合は、該混合物中に含まれる成分(B)をいうものとする。
すなわち、成分(B)に由来する構成要素に対する成分(A)に由来する構成要素のモル比(A)/(B)は、天然由来繊維内で形成する両者の縮合物により、処理後の天然由来繊維の形状持続性と強度をより一層優れたものとする観点及び良好な感触の観点から、好ましくは0.1以上20未満、より好ましくは0.3~15、更に好ましくは0.5~10、更により好ましくは0.5~7.5である。

本発明の繊維処理剤が1剤式である場合、成分(A)及び(B)との反応により、繊維処理剤中に分子量の大きな不溶性の縮合物が生成すると、天然由来繊維の表面に硬い樹脂の層が形成されることで、天然由来繊維の屈曲や延伸といった運動が制限され、繊維の伸縮性(粘り強さ)を妨げてしまうのみならず、繊維表面の感触も悪化してしまう場合もある。このため、1剤式の繊維処理剤は、反応の過程で生成し濁度上昇の原因となる成分(A)及び(B)からなる縮合体オリゴマーの凝集を防ぎ溶解させやすくする観点から、ハンセンの溶解度パラメータのSP値が16MPa1/2以上40MPa1/2以下である有機化合物(ただし、有機塩及びアルデヒド基を有する分子量150以下の化合物を除く)を含有することが好ましい。電荷を有する有機塩は、系中に共存すると濁度が急上昇してしまい、またグルタルアルデヒドのようなアルデヒド基を有する化合物は、成分(B)のフェノール化合物同士を多点で架橋して濁度を急上昇させるため、成分(D)からは除外される。

表1に示す処方の組成物を用い、下記方法に従って再生コラーゲン繊維を処理し、各種評価を行った。なお、各組成物のpHは、調製した組成物を室温(25℃)において、そのままpHメーター(HORIBA社製、F-52)で測定した。また、組成物の濁度は、室温(25℃)において、繊維処理剤をそのままデジタル濁度計(アズワン社製/型番:TB700/測定方法:ISO7027比濁法(90°)準拠/光源:赤外線放射ダイオード(850nm)/検出器:結晶シリコン太陽電池モジュール)の測定セル(φ25 x 60mmホウケイ酸ガラス)に入れて測定した。
1.再生コラーゲン繊維(※)0.5gの長さ22cmの毛束を、繊維処理剤40gが入った容器に浸漬し、容器の口を密閉し、容器ごと50℃のウォーターバス(製造元:株式会社東洋製作所/型番:TBS221FA)に浸漬し所定の時間加熱した。加熱時間は、実施例7以外については、約0.6T(Tは前述のとおり)に相当する時間で統一した。実施例7については、工程(0)を0.3Tに相当する時間加熱した上で繊維を浸漬し、更に0.3Tに相当する時間加熱する操作を2回行った。
※:カネカ社製再生コラーゲン繊維を市販エクステンション製品の形態で購入し、そこから繊維を切り取り毛束に小分けして評価に使用した。今回の評価では、エクステンション製品に繊維種としてUltima100%使用表記があり、色番手が3のブラウン、形状ストレートのものを使用した。
2.毛束の入った容器をウォーターバスから取り出し、室温に戻した。
3.毛束を容器から取り出し、トリエチレングリコール50gの中に30秒間浸漬した後、水道水の30℃流水にて30秒すすぎ、評価用シャンプーで60秒泡立て、水道水の30℃流水にて30秒すすぎ、タオルで軽く水気を切った後、毛束を温風ドライヤー(テスコム社製、Nobby ホワイトNB3000)でコーミングしながら乾かした。この時点で、毛束は直毛のままであった。
繊維引張時の伸縮性(粘り強さ)の指標として、平均破断伸度、すなわち引張で繊維が延伸されていったときに元の繊維長に対して何%延伸されたところで破断が起こるかについて、複数本(10本)の繊維で評価したときの平均値を用いた。評価は、上記<処理方法>で処理された直後の毛束を用いて、以下の手順で行った。
1.毛束の根本から、繊維10本を切り取った。それぞれの繊維の根本と毛先の中間付近から3cmの繊維片を採取し、合計で10個の3cmの毛髪片を得た。
2.繊維片をDIA-STRON limited社製「MTT690 繊維自動引張り試験機」にセットして自動測定を開始し、繊維が濡れた状態での平均破断伸度を求めた。数値が高いほど、伸縮性が高く粘り強さに優れ、耐久性にも優れることを示す。
次式に従い、市販品から切り取ったそのままの状態(未処理)での繊維引張時の平均破断伸度(A%)を基準とし、処理後の毛束の平均破断伸度(B%)が、未処理の状態からどの程度(C%)増加したかを、表中に「繊維引張時の平均破断伸度の増加率 [%]」として記載した。

2.繊維片をDIA-STRON limited社製「MTT690 繊維自動引張り試験機」にセットして自動測定を開始し、繊維が濡れた状態で延伸したときの破断荷重を求めた。数値が高いほど、ハリコシがあって外力による延伸に強く、耐久性にも優れることを示す。
次式に従い、市販品から切り取ったそのままの状態(未処理)での繊維引張時の平均破断荷重(W0(gf))を基準とし、処理後の毛束の平均破断荷重が、未処理の状態からどの程度(Y(gf))増加したかを、表中に「繊維引張時の平均破断荷重の増加量 [gf]」として記載した。
Y(gf)=W1(gf)-W0(gf)
高温アイロンセット時の収縮抑制は、上記<処理方法>で処理された直後の毛束を用いて行った。また、数値としては複数本(10本)の繊維で評価したときの平均値を用いた。評価は、以下の手順で行った。
