Study On Process On Enzyme Finishing For Natural Colored Cotton Fabric

The configuration of natural colored cotton is similar to ordinary cotton, but the naturally colored cotton's cell is bigger than ordinary cotton, and the second cell wall is also thicker. The coloring material in naturally colored cotton mainly distributed in cell, and some distributed in second cell wall. The stability of naturally colored cotton' coloring material is inferior, it changes with the outer factors easily. First, this article studies the changing law of coloring material in green and brown naturally colored cotton, such as dealing with different acids, alkali, temperature, time and process, then analyzes and sums up. Second, on the basis of the changing law, conventional method for water absorbency, strength and color fastness. The improved hand and increased strength as well as the reduced environmental impact and the advantages of the enzymatic method. Finish of naturally colored cotton knitted fabric with designed enzyme finishing process can improve wear ability and color fastness to washing, rubbing and perspiration and is a optimum choice in finishing process.
