維又はその製品として得ることができる。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method for modifying raw silk fibers or their products by making them insoluble while keeping sericin attached thereto and fixing sericin therein. By applying this aldehyde to sericin fixation on raw silk fibers, it is possible to obtain raw silk fibers or products thereof with a desired amount of sericin stably fixed thereon.

当量のセリシンを定着させうれば資源の有効利用
から鑑みて染色加工上、重要視されうる。 Generally, the content of sericin in raw silk fibers or their products is high, around 25%, and if it is possible to fix an appropriate amount of sericin without discarding sericin, it would be important in dyeing processing from the standpoint of effective resource utilization.

られなかつた。b. Prior Art The formaldehyde method and glutaraldehyde method, which have been widely used as cellulose modifiers and protein tissue fixatives, have been used as relatively simple methods to fix sericin on raw silk fibers or their products. Crosslinking of these aldehydes is further promoted by heating and reacting them with raw silk fibers and the like. The present invention is also an application of this, and only slight effects were obtained with saturated aliphatic aldehydes.

セリシン定着による改質を提供するものである。c. Purpose of the invention A treatment method that fixes sericin in raw silk fibers or their products without discarding them, which can be a source of pollution in lakes and rivers, by immersion treatment in an aqueous solution containing 2-butenal (crotonaldehyde). The present invention provides a method for modifying raw silk fibers or products thereof by fixing sericin on the fibers, which is characterized by insolubilizing and fixing sericin on the fibers.

る。d. Structure of the invention In other words, 2-butenal (crotonaldehyde) is a liquid compound represented by CH 3 CH = CHCHO, and is used for refining mineral oil, manufacturing resin, antioxidant for rubber, insecticide, etc. . The present invention is a modification by sericin fixation in which an appropriate amount of sericin is insolubilized and fixed on raw silk fibers or products thereof by soaking the raw silk or silk products in an aqueous solution containing 2-butenal (crotonaldehyde). It is thought that the double bond in crotonaldehyde is involved in the sericin fixation reaction.
以下実施例により本発明の結果を具体的に示
す。 The results of the present invention will be specifically shown in Examples below.

常温で乾燥し、さらにデシケータ中で再乾燥を行
つた。Example 1 Using 27 medium raw silk (1981 spring silkworm) washed with ether and alcohol, the bath ratio (1:50) was adjusted to the sample raw silk. After adjusting the concentration of 2-butenal (crotonaldehyde) to 3% of this bath ratio and immersing it at room temperature for 4 hours, it was washed twice with acetone at room temperature, washed lightly with distilled water, then wrung out and dried at room temperature. Then, it was further dried again in a desiccator.
通常、未処理生糸のセリシン含有量は25％前後
とかなり高い数値を示しているが、本法の２−ブ
テナール（クロトンアルデヒド）処理では練減率
は10％前後を示す。 Normally, the sericin content of untreated raw silk is quite high, around 25%, but when treated with 2-butenal (crotonaldehyde) in this method, the reduction rate is around 10%.
強伸度としては、未処理生糸の強度は4.0ｇ／
ｄで伸度は25％であり、一方の２−ブテナール
（クロトンアルデヒド）による処理生糸の強度と
伸度は4.2ｇ／ｄと23.6％である。 In terms of strength and elongation, the strength of untreated raw silk is 4.0g/
The strength and elongation of raw silk treated with 2-butenal (crotonaldehyde) are 4.2 g/d and 23.6%.

のままの処理生糸でも、染色時の黒色染めなどに
も応用できる。 Therefore, by this treatment method, approximately 15% of sericin can be insolubilized and fixed on raw silk. These treated raw silks have a bright yellow color, but even treated raw silks without bleaching can be used for black dyeing during dyeing.
