Chestnut trees have been used as a dyeing material, which are grow naturally, are cultivated all the area of Korea. So, there is abundant amount of the materials and they have better colorfastness than other natural dyeing materials. But chestnut husk extract is good at silk and wool fabrics, not cotton fabrics. That's why many methods using chestnut extraction for dyeing are being studied. But most of them depend on treatment method with chemical material which doesn't fit with the aim, using natural materials. Therefore in this research, we used protein pre-treatment method which is dyeing chestnut husk extract after treating at cotton fabrics with bean sap. And we studied the effect of dyeability of chestnut husk extract to cotton fabrics. As a result of pre-treatment of bean sap at cotton fabrics, dyeability was increased. Besides laundering fastness, dry cleaning fastness, perspiration fastness and light fastness were almost increased.

To increase dyeability of cotton fabric to the chestnut shell dyeing, we had several dyeing experiments with the experimental fabrics which was pre-treated by soybean, NaOH, KOH. Three kinds of experimental cotton fabrics were used and chestnut shell dyebath was made for the experiment. Munsell's color HV/C and color differences ΔE of dyeing fabrics were compared between pre-treatment and none pre-treatment dyeing fabrics. The main results were as follows ; Color differences of dyeing fabrics pre-treated with soybean, NaOH, KOH were higher than those of none pre-treated dyeing fabrics. In case of pre-treatment with soybean, the concentration of the soybean bath affected the color differences but not affected in case of pre-treatment with NaOH & KOH. Munsell's color of pre-treatment fabrics with soybean, NaOH, KOH were same with the none pre-treatment fabrics. Colorfastness of the pre-treated fabrics were same degree, but only in case of soybean pre-treated fabrics were low in fastness of washing(change) & perspiration(acidic change).
