Abstract :一般に紅型に使われている顔料の性質は耐光性に強く, 耐摩擦に弱いといわれているが, やはり今回の実験結果を通しても同じようなことがいえるようである。肉眼判定の結果からも家庭でする洗たく法では押し洗いがよく, その他にはドライ・クリーニングが適当で, 摩擦をともなう刷毛洗い, もみ洗いはさけた方がよいようである。又洗剤は上質の中性洗剤を用いた方がよいということがいえる。洗たく法の押し洗い, ドライ・クリーニングの際にも全く色素がおちないとは言えず回数を重ねる毎に色素の変退色が見られることは明らかである。その洗剤溶液中に溶出した色素の移行を白布に逆汚染させて, その堅牢度を判定したが, 余り適当とは思われないので, 色の溶出が直接に数値で判定される方法で実験することを今後の研究課題にして行き度いと考えている。
The Bingata pattern is being evaluated of its value as its products are met with a growing demand on foreign markets year after year. It is noted, however, that few people have ever attempted to make research on the method of the care and preservation of the Bingata dyes. In view of this, the writer decided to work on the subject theme. In this paper the writer attempted to show the results of experiments in the durability for washing, abrasion strength and light resistance of the Bingata dyes. The methods employed for the experiments were those specified by the Japan Standards Association; the Gray Scale was used grading. Test materials were dyed by fabrics-cotton, ramie, silk, and basho (banana cloth). The pigments used were : red, pink, yellow, carmine, brown, violet, green, light blue, blue, and black. As a result, it was revealed that the Bingata dyes compared favorably with commercial dyes in respect to their properties as pigments. However, the experiments showed a lower grade in the case of the black dye. The washing soap for use should be a superior neutral one. Color fading is more eminent in the high humidity than in the low. Hence, a care must be taken in washing. The exposure test revealed satisfactory results on the whole. However, fading was conspicuous in the case of colors mixed with a large amount of the white pigment, such as light blue, green and pink. Of all home laundry methods, theoshiarai(press gently in water) and dry cleaning methods proved to be the best to obtain good results. Finally, it seems necessary to devise methods other than the above-mentioned ones in order to obtain more accurate figures as to the fading degree of Bingata.
