に染色することができないものであった。The above-mentioned protein fibers are generally dyed with anionic dyes such as acid dyes, direct dyes and reactive dyes, but when a clear color that cannot be obtained with anionic dyes is required, it is basic. Sometimes used dyes. However, basic dyes have a problem in practical use because they have extremely low dyeing fastness, and cationic dyes for acrylic fibers have a clear color and are excellent in dyeing fastness, but they can be dyed in dark colors. It was impossible.

の問題点を解決する方法が嘱望されていた。<Problems to be Solved by the Invention> As described above, in dyeing protein fibers, a dye or a dyeing method having a dyeing fastness that can withstand a vivid color and practical use is not yet proposed, and There are still no examples of chemical anti-dyeing methods for anionic dyes that have been put to practical use. Therefore, there has been a strong demand for a method of solving each of the above problems.

製造法に関するものである。<Means for Solving the Problems> The present invention has been proposed in view of the above, and the protein fiber is constituted by immersing the protein fiber in an organic solvent solution of anhydrous O-sulfobenzoic acid and heating it. A protein with a modified dyeing property, which is characterized by chemically introducing a sulfone group into the molecule of the protein and imparts dye-proofing property to anionic dyes and sensitizing property to cationic dyes. The present invention relates to a fiber and a manufacturing method thereof.

きるものである。The dye-modified protein fiber of the present invention has anti-dyeing properties for anionic dyes and sensitizing properties for cationic dyes as described above, but has the above-mentioned characteristics. Can be achieved by chemically introducing a strong anion group into the protein molecule constituting the protein fiber.

COOH, etc.) and a basic group (-NH 2, etc.) in common, but a basic group such as amino acid (-NH 2 ) or hydroxyl group (-OH), a strong anion group such as sulfone group ( -SO 3 H) makes it possible to impart an ionic repulsive force to anionic dyes to impart dye resistance and an ionic affinity to cationic dyes to impart sensitizing properties. .
上記した蛋白質分子内のアミノ基或いは水酸基として
は、蛋白質を構成するアミノ酸の一つであるリジンの側
鎖のアミノ基、 チロシンの側鎖のフェノール水酸基、 等を挙げることができる。As the amino group or hydroxyl group in the protein molecule described above, the amino group of the side chain of lysine, which is one of the amino acids constituting the protein, Phenolic hydroxyl group on the side chain of tyrosine, Etc. can be mentioned.

度を必要とする。The above-mentioned amino group of the side chain of lysine and anhydrous O-sulfobenzoic acid, However, the reaction between the phenolic hydroxyl group of the side chain of tyrosine and O-sulfobenzoic anhydride requires a high treatment temperature.
従って、蛋白繊維に対する無水Ｏ−スルホ安息香酸の
反応性、即ちスルホン基の導入のしやすさは、蛋白質を
構成するアミノ酸の種類と構成割合によって異なるもの
である。Therefore, the reactivity of anhydrous O-sulfobenzoic acid with respect to protein fibers, that is, the ease with which a sulfo group is introduced, differs depending on the type and composition ratio of the amino acids constituting the protein.

れよりも高いものでなければならない。That is, taking the above-mentioned lysine and tyrosine as an example, merino wool (keratin) contains 3.3 wt% lysine and 6.4 wt% tyrosine.
%, Silk (fibroin) is 0.4wt% lysine
%, Tyrosine 13.8 wt%, merino wool contains a lot of lysine, and silk contains a lot of tyrosine. Therefore, the treatment temperature for reacting O-sulfobenzoic anhydride to silk in the present invention should be higher than that of merino wool.
通常、羊毛における本発明の具体的な処理方法は、５

~ 40% in a bath of ~ 25% anhydrous O-sulfobenzoic acid
In the treatment of silk, on the other hand, immersion in the above-mentioned bath at a temperature of 60 to 80 ° C. for 60 to 120 minutes is most suitable for practical use.

キシドが最も効果的であった。Further, as the reaction medium in the reaction for introducing the sulfone group of the above-mentioned O-sulfobenzoic anhydride, a general organic solvent can be used, but dimethylformamide or dimethylsulfoxide having a high swelling ability for protein fibers is used. It was the most effective.

きるので、鮮明な色を有する蛋白繊維製の服飾品を得る
ことができる。また、本発明の蛋白繊維は、アニオン染
料に対して防染性を有するので、通常の蛋白繊維との併
用により複数の色を有する織物を作製することができ
る。Therefore, the protein fiber of the present invention can be used to dye protein fibers such as silk and wool with a brightly colored cationic dye, so that a clothing made of protein fiber having a bright color can be obtained. . In addition, since the protein fiber of the present invention has a dye-proof property against anionic dyes, a woven fabric having a plurality of colors can be produced by using it in combination with ordinary protein fibers.
また、本発明の蛋白繊維は、蛋白繊維の特徴である水
分吸収性及び機械的性質（特に長範囲の弾性）を損なう
ことがなく、通常の蛋白繊維と同様な保温性や装着感を
維持するものである。Further, the protein fiber of the present invention does not impair the water absorbency and mechanical properties (especially long-range elasticity) which are the characteristics of the protein fiber, and maintains the same heat retention and wearing feeling as ordinary protein fibers. It is a thing.
さらに、本発明の染色性を改質した蛋白繊維の製造法
は、特別な装置や設備を必要とするものでないので従来
の物理的な防染法に比べて実用的価値は極めて高い。Further, the method for producing a protein fiber having a modified dyeing property of the present invention does not require a special device or equipment, and therefore has a very high practical value as compared with the conventional physical dye-resisting method.
