Introduction To The Finishing Process Of Knitted Denim Fabric

- Oct 10, 2019-

The finishing of knitted denim fabric is an important part of the knitting industry. Enzymes, like enzymes, can be used to degrade cellulose in cotton fibers. Since the color of the denim is actually attached to the outer layer of the yarn, the enzyme is washed with water to wash off the fibers together with the indigo dye attached to it. When the desired color is obtained, the enzyme wash can be stopped by changing the alkalinity of the water or raising the temperature of the water. Then proceed to the next rinse and soft treatment. Enzyme washing is milder than stonewashing because there are no sharp-edged stones in the enzyme washing process. Denim washed with enzymes has a uniform color and soft feel for home textiles and clothing.

Stonewashing is a physical method of fading denim and adding color contrast. A 20-yard-long, 62-inch-wide roll of cloth was placed in a 250-pound, pumice-filled wash tank for stonewashing (the best water wash when the cylinder capacity was 35%). In the washing tank, the denim and the stone are mixed and tumbling, rubbing each other, and the length of the tumbling time determines the depth of the color after the denim is washed. The longer the washing time, the lighter the color, the stronger the color contrast effect. After the denim is washed, it is rinsed, softened and dried. The denim fabric that has been washed by stonewashing is rich in color and rich in color. It has become the fashion choice fabric for the home textile industry and the clothing industry.

In the post-finishing process, the combination of pumice and enzymes gives the denim a nostalgic effect. In the first step, only the pumice and fabric are placed in the washing tank, and then the enzyme is placed in the next step, and rolled together with the pumice and the fabric until a natural nostalgic effect is produced. The most commonly used method of washing is blue denim.
