Knowledge Of Finishing Process For Jeans Washing

:

At present, most denim is softened by cellulase rinsing.

When producing denim, no matter how thick or thin, the warp will be coated with a corn starch slurry to improve the yarn stiffness.

During desizing, cellulase can decompose the size of denim and make the pulp peel off.

Although the desizing will slightly fade the denim, it will improve the softness and drapability of the denim.

The thin denim made of desizing can be made into a table cloth or napkin cloth with soft handle and good drape.

Wash with stone mill:

Stone washing is a physical method to fade denim, and increase the contrast effect of color.

Put a cloth of 20 yards long and 62 inches wide into the washing tank weighing 250 pounds and pumice stone and wash it with stone mill (the best washing effect is 35%).

In the washing cylinder, the denim and the stone are mixed and rolled, rubbed together, and the length of the roll time determines the depth of the denim's color after washing. The longer the washing time is, the lighter the color is,

The more intense.

Denim washes, rinses, softens and dries after washing. The soft and colorful layers of denim that are washed and washed by stone mill become the fashion preferred fabrics of home textile industry and garment industry.

Enzyme wash:

Enzymes, like enzymes, can be used to degrade cellulose from cotton fibers.

Because the color of denim is actually attached to the outer layer of the yarn, after washing the water with enzymes, the fibers and the indigo dye attached to it can be washed away together.

When the desired color is obtained, the enzyme washing water can be stopped by changing the alkalinity of the water or increasing the water temperature.

Then rinse and soften the next step.

Enzyme washing is more mild than washing with stone, because there is no sharp stone in the process of enzyme washing.

The jeans washed by enzyme are uniform and soft, which is suitable for home textiles.

Washed by stone mill.

During the finishing process, pumice and enzymes are used to make the denim available.

In the first step, only the pumice and fabric are added into the cylinder, then the enzyme is placed in the next step and rolled together with the pumice and fabric until the natural nostalgia is generated.

Blue jeans are the most frequently used method of washing.

Sand washing:

The finishing uses a row of horizontally placed rollers, which can be coated with sandpaper or chemically treated abrasives.

The denim is sleeved on the roller, and the convex part is ground by sand.

This finishing method will partly fade the denim and produce a velvet feel on the denim surface, giving it a soft and delicate handle.

Sand washing can also make wrinkles, cat whiskers and so on.

Appearance effect.

Finalize and sort out:

For cowboy fabrics, it is feasible and necessary to use several finishing methods at the same time.

Because cowboy dyes are attached to the surface of yarns, it is a problem for manufacturers to solve to prevent other fabrics from being dyed by denim.

Resin and fixing agent can avoid the problem of color fading, especially for darker colors.

Besides, waterproofing treatment also helps to prevent the fading of finishing and wearing.
