No.5（2002）29.Enzyme Treatment of Textile Fabrics, Swelled with Inorganic Salts

Kengo KOBAYASHI and Chiaki KIMURA

We attempted to develop a method to transfer designs onto cellulosic fabrics using the enzyme treatment. In order to achieve this, we printed the T/C broadcloth with paste including calcium thiocyanate, which enabled the cellulosic fiber to swell before the enzyme treatment. Then the printed and the unprinted T/C broadcloths were dipped in an aqueous solution of the cellulase and the weight loss of T/C broadcloths by the cellulase treatment was measured. The printed T/C broadcloth showed about 5 times as much weight loss as the unprinted T/C broadcloth, when these cloths were treated with a solution of 4 g/L of cellulase for 120 minutes at 50℃. For practical purposes, the T/C broadcloth was printed with the paste including calcium thiocyanate, using the designed screen and treated with the cellulase solution. Then the watermarked design was made on the T/C broadcloth based on the difference between the weight loss of printed parts and the weight loss of unprinted parts. The weight loss of the printed linen broadcloth, treated in the same way was not as much as the printed T/C broadcloth. As a result, we found that there was a posibility of transfering the watermarked designs onto blended yarn cloth made from cotton and linen.
