x******d

Mech is meticulously manufactured. It has gone through those manufacturing processes, namely, cutting, sewing, fiber washing, dyeing, combing, and finishing.

i******r

Mech is guaranteed by quality assessment. Its manufacturing workmanships such as cutting, sewing, and dying, and some chemical agents used such as dyestuff and anti-bacterial agents are required to pass relevant tests.

g******h

The product is antibacterial. It is treated with antibacterial agents which damage the microbial structure and kill the cells of bacteria.

n******e

The product will not generate static. During the treatment of the material, it has been treated with the antistatic agent.

m******d

The product is bacteria resistant. It will be processed with the antibacterial agents which damage the microbial structure and kill the cells of bacteria in the fibers.

j******o

It is smooth and soft. During the production, the raising process, which allows the fabric surface to treat with sharp teeth to lift the surface fibers thereby imparting hairiness and softness, is conducted.
