問題点を解決する方法が嘱望されていた。<Prior Art> As is well known, silk and wool are protein fibers composed of about 18 types of amino acids, and their specific heat and gravity are generally similar to those of the human body, so clothing made from protein fibers is The material is said to be comfortable to wear. The protein fibers mentioned above are generally produced using acid dyes, direct dyes,
Although it is dyed with anionic dyes such as reactive dyes, basic dyes were sometimes used when a vivid color that could not be obtained with anionic dyes was required. However, basic dyes have extremely low color fastness, which poses a practical problem, and cationic dyes for acrylic fibers have vivid colors and excellent color fastness, but cannot be dyed in deep colors. It was impossible. On the other hand, as a resist dyeing method to prevent protein fibers from being dyed with anionic dyes,
For example, mechanical or physical resist dyeing methods such as shibori, kukuri, board-jime, and wax-tying, in which a part of the material to be dyed is bound with thread to prevent it from being dyed, have been known for a long time. However, no successful example of chemical resist dyeing has yet been proposed. <Problems to be Solved by the Invention> As mentioned above, in dyeing protein fibers, a dye or dyeing method that produces vivid colors and has a color fastness that can withstand practical use has not yet been proposed. There are still no examples of chemical resist dyeing methods for anionic dyes that have been put into practical use. Therefore, a method has been desired to solve each of the above-mentioned problems.

るものである。Means for Solving the Problems> The present invention was proposed in view of the above, and involves the process of laterally forming protein fibers by immersing them in an organic solvent solution of 0-sulfobenzoic anhydride and heating them. A protein fiber with improved dyeability, characterized in that it has a sulfone group introduced into the molecule of a protein that imparts resistance to anionic dyes and dyeability to cationic dyes. It concerns the manufacturing method. The protein fiber with improved dyeability of the present invention has resisting properties against anionic dyes and dyeing properties against cationic dyes as described above, but does not have the above-mentioned properties. This can be achieved by chemically introducing strong anion groups into the protein molecules that constitute protein fibers.

It shares a basic group (-Nl{, etc.) with the basic group (-Nl+21 or hydroxyl group (-0}1), which is a strong anionic group. By introducing a sulfone group (-SQ.H),
Ionic repulsion works against anionic dyes to improve dye resistance.
In addition, cationic dyes have ionic affinity and can be given dye enhancement properties. The amino groups or hydroxyl groups in protein molecules that have been introduced include the amino group on the side chain of lysine, which is one of the amino acids that make up proteins, (CH.). -CH. Examples include monovalent h -NH-Cl{-GO- phenol hydroxyl group on the side chain of tyrosine, CL-O-X-NH-CH-CO-, and the like. The above reaction between the amino group of the side chain of lysine and O-sulfobenzoic anhydride is easily carried out, but the reaction between the phenol hydroxyl group of the side chain of tyrosine and O-sulfobenzoic anhydride requires a high treatment temperature. .

らない。Therefore, the reactivity of anhydrous 0-sulfobenzoin to protein fibers, that is, the ease with which sulfone groups can be introduced, differs depending on the type and composition ratio of amino acids constituting the protein. That is, taking the above-mentioned lysine and tyrosine as an example, merino wool (keratin) contains lysine 3. Silk (sigloin) contains 3 wt% of lysine and 6.4 wt% of lysine. Merino wool contains a large amount of lysine, and silk contains a large amount of tyrosine. Therefore, the treatment temperature for reacting O-sulfobenzoic anhydride with silk in the present invention must be higher than that of merino wool.

に最も適している。Usually, the specific treatment method of the present invention for wool is 5 to
Temperature 40-6 in a bath of 25% O-sulfobenzoic anhydride
In contrast, in the treatment of silk, the temperature is 60°C in the bath described above.
Immersing for 60 to 120 minutes at ~80°C is most suitable for practical use.

シドが最も効果的であった。In addition, general organic solvents can be used as the reaction medium in the reaction for introducing the sulfonic group of 0-sulfobenzoic anhydride, but dimethylformamide or dimethyl sulfoxide, which has a high swelling ability for protein fibers, is preferable. It was the most effective.

It can be obtained simply by dipping it in a bath of anhydrous O-sulfobenzoic acid and heating it, and it has extremely good dyeing properties for cationic dyes that can impart vivid colors. You can get clothing items made from textiles.

It also imparts resistance to anionic dyes to protein fibers, and is a chemical resistance dyeing method as opposed to the conventional physical resistance dyeing method. By combining these fibers to create a fabric and dyeing it with an anionic dye, it is possible to create a fabric in which only the normal protein fibers are dyed.

した。In addition, the dyeability of wool against cationic dyes and the resistance against anionic dyes are similar to those of silk described above, and the resistance against anionic dyes is 13% in weight increase rate.
It is clear that the above examples (Example 5 and Example 6) are extremely good. ■ Measurement of washing fastness The treated fabric of Example 2 above was placed in an acetic acid bath (pH 4, bath ratio 40:l) of each cationic dye shown in Table 2 at a temperature of 8.
Staining was carried out at 5°C for 30 minutes. After each dyed fabric was washed with water and dried in the same manner as described above in (1) Dyeability, K/S was determined, and washing fastness was further tested in accordance with JIS LO844-A2. Washing fastness was evaluated in two categories: discoloration and staining, and the results are shown in Table 2.

。<<Effects of the Invention>> As explained above, the protein fiber with improved dyeability of the present invention exhibits excellent dyeability against cationic dyes and resists against anionic dyes. ．． Therefore, the protein fiber of the present invention allows protein fibers such as silk and wool to be dyed using a cationic dye with a bright color, so that it is possible to obtain clothing items made of protein fiber with a bright color. ．． Furthermore, since the protein fiber of the present invention has resisting properties against anionic dyes, it is possible to produce textiles having a plurality of colors 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。In addition, the protein fiber of the present invention does not impair the moisture absorption and mechanical properties (particularly long-range elasticity) that are characteristic of protein fiber, and maintains the same heat retention and wearing comfort as ordinary protein fiber. It is something.
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。Furthermore, the method for producing protein fibers with improved dyeability according to the present invention does not require any special equipment or equipment, and therefore has extremely high practical value compared to conventional physical resist dyeing methods.
