（産業上の利用分野）
本発明は、絹糸、絹織物等の絹製品の加工方法に関する

（従来の技術）
絹繊維は光沢、染色性、力学的性質及び吸放湿性など衣

マー等のグラフト重合加工剤が一般に知られている。(Prior art) Silk fiber has excellent properties as a clothing fiber, such as luster, dyeability, mechanical properties, and moisture absorption/desorption properties. It has various properties that make it unsuitable as a material for modern clothing. Therefore, as processing agents for improving or improving the functional utility of silk fibers, graft polymerization processing agents such as hydrophilic vinyl monomers represented by styrene, methyl methacrylate, 2-hydroxyethyl methacrylate, and methacrylamide are used. is generally known.
（発°明が解決しようとする問題点）

かでやわらかな絹本来の柔軟的な性質は損われ、防しわ
性を低下させることに加えて、該加工剤は悪臭を有する
ため取扱いにくいという不都合を有する。(Problems to be Solved by the Invention) Among the conventional processing agents mentioned above, the former styrene and methyl methacrylate processing agents increase the Young's modulus of silk as the grafting reaction progresses when used for silk products. However, the pliable and soft properties of unprocessed silk are impaired, and in addition to reducing the wrinkle resistance, the processing agent has a bad odor and is difficult to handle.
また後者の親水性ビニール系モノマー加工剤は、絹製品

のｌ／３近くにまで低下し、かつ絹糸のやわかさや伸び
易さの目安となる初期引張抵抗度が増加して絹糸は固く
、伸び難くなるとともに、その染色性能が低下するなど
の問題を有する。The latter hydrophilic vinyl monomer processing agent is used when processing silk products by adding an acid to the mixed solution containing the processing agent to adjust the pH, and then adding a polymerization initiator under certain conditions. It is quite difficult to control the temperature because it requires temperature control, and the cross-sectional area of the silk increases as the grafting reaction progresses, so the silk strength per silk fineness is close to 1/3 of the unprocessed state. As a result, the initial tensile resistance, which is a measure of softness and stretchability of the silk thread, increases, making the silk stiff and difficult to stretch, and the dyeing performance of the silk thread decreases.
本発明は、前記問題点を解消し、未加工絹製品と同等の
優れた機械的性質が得られると共に、防しわ率、黄変防

工方法を提供することを目的とする。The present invention solves the above-mentioned problems, and provides a method for processing silk products that can provide excellent mechanical properties equivalent to those of unprocessed silk products, as well as improve wrinkle resistance, yellowing resistance, and dyeability. The purpose is to provide
（問題点を解決するための手段）
本発明者は、前記目的を達成する絹製品の加工方法につ

、優れた黄変防止効果があることを知見した。(Means for Solving the Problems) As a result of intensive study on a method for processing silk products that achieves the above object, the present inventor has discovered that by using a processing solution consisting of an organic solvent containing a dibasic acid anhydride, It was found that mechanical properties such as strength, elongation, and initial tensile resistance equivalent to those of processed silk products can be obtained, and that it has improved wrinkle resistance and dyeability, and has an excellent yellowing prevention effect.
本発明は、前記知見に基づいてなされたものであって、
一般式
（ただし式中ｎは２〜４である）
で示される２塩基酸無水物を含有する有機溶剤から成る
加工溶液で浸漬処理することを特徴とする。The present invention has been made based on the above findings, and includes immersion treatment with a processing solution consisting of an organic solvent containing a dibasic acid anhydride represented by the general formula (where n is 2 to 4). It is characterized by

れる。また有機溶剤としては、ジメチルホルムアミド、
ジメチルスルホキシド、ピリジン等の塩基性有機溶剤が
挙げられる。Examples of dibasic acid anhydrides used in the processing method of the present invention include succinic anhydride, glutaric anhydride, and adipic anhydride. In addition, examples of organic solvents include dimethylformamide,
Examples include basic organic solvents such as dimethyl sulfoxide and pyridine.
有機溶剤中における２塩基酸無水物の濃度を０．１〜１
．５Ｍとする。The concentration of dibasic acid anhydride in the organic solvent is 0.1 to 1.
．． It will be 5M.
絹糸または絹製品を浸漬する溶液は前記濃度溶液の浴比
２０倍前後が好ましく、また溶液の温度は５０〜８５℃
、好ましくは７５℃前後であり、浸漬時間は３０〜４８
０分間、好ましくは２４０分間とする。The solution in which the silk thread or silk product is immersed is preferably about 20 times the bath ratio of the above concentration solution, and the temperature of the solution is 50 to 85°C.
, preferably around 75°C, and the immersion time is 30 to 48
0 minutes, preferably 240 minutes.
浸漬処理後はイソプロパツールのような低級アルコール
で洗浄し、更に水洗処理を施して絹糸または絹製品から
未反応２塩基酸無水物等を完全除去させる。After the soaking treatment, the silk thread or silk product is washed with a lower alcohol such as isopropanol, and further washed with water to completely remove unreacted dibasic acid anhydride and the like from the silk thread or silk product.

するためと考えられる。The yellowing prevention property is improved by using a processing solution consisting of an organic solvent containing a dibasic acid anhydride.
This is thought to be because the basic acid anhydride reacts selectively with the active OH group of the side chain of the tyrosine molecule in the silk molecule, which is one of the causes of yellowing.
