The purpose of mercerization:

1. Improve the surface gloss and feel of fabrics

Due to the expansion of fibers, they are arranged more neatly and reflect light more regularly, thereby improving glossiness.

2. Improve dyeing yield

After mercerizing, the crystal area of the fibers decreases and the amorphous area increases, making it easier for dyes to enter the interior of the fibers. The coloring rate is 20% higher than that of non mercerized fiber cotton cloth, and the brightness is improved. At the same time, it increases the covering power for dead surfaces.

3. Improve dimensional stability

Mercerizing has a shaping effect, which can eliminate rope like wrinkles and better meet the quality requirements of dyeing and printing for semi-finished products. The most important thing is that after mercerization, the stability of fabric expansion and deformation is greatly improved, thereby greatly reducing the shrinkage rate of the fabric.
