Underwear Production Underwear Production Process How To Make Underwear

1, selection:

because a href= "http://fz.sjfzxm.com/" > underwear < /a > all directly contact with the skin, so the choice of materials must be quite exquisite, usually from the harmful ingredients, hygroscopicity, antistatic, skin touch, dye perspiration fastness and washing fastness (color fastness), < a target= "_blank" href= "//www.sjfzxm.com/" > fabric > /a > elasticity, strength and so on.

Because natural fiber is superior to chemical fiber in moisture absorption, skin touch and antistatic, and at the same time, because knitted fabric is better than woven fabric in elasticity, underwear fabrics are mostly knitted with natural fibers. In order to increase the elasticity of fabrics, high elastic fabric with spandex is usually used.

harmful ingredients mainly refer to the harmful chemicals remaining in the dyeing process, which are easily absorbed by the skin during the dyeing process. The hygroscopicity mainly refers to whether the human body can be absorbed effectively after sweating, and it is easy to cause bacterial infection for a long time in the condition of poor moisture absorption. It is not good for static electricity and body skin feeling, and it will feel uncomfortable in the wearing process. The color fastness and washing fastness of dyes are not good. It is easy to cause the dye molecules to fall off or even be absorbed by the skin and cause diseases in the process of wearing. The elasticity and intensity of the cloth will affect its comfort and durability.

2, sticky cloth:

sticky cloth is to bind the cloth and sponge adhesive. After bonding, the surface of the cloth must be smooth, and the adhesive and its solvents which are harmful to human body can not be used in the process of sticking, such as adhesives containing formaldehyde and acetone. Otherwise, these ingredients will remain in the clothing material and will affect the health of the human body.

generally it is first typesetting and tailoring. In the typesetting, we should pay attention to the texture of fabrics and arrange them rationally according to their performance.

If the direction of the left and right film is not consistent, the elasticity of the left and right pieces of the finished product will be different. When wearing, the two sides will be found to be different in size.

shear straps and shoulder straps are usually made by cutting a long shoulder strap to a certain length according to the requirements, then wearing shoulder strap buckles, stitching with a single needle sewing machine, or sewing with a knot stitch machine.
