Women's underwear sewing process general process:
1, material selection.Because lady underwear contacts skin directly, so select material must be quite exquisite, usually from the sweat stain fastness of have without harmful component, hygroscopic sex, antistatic sex, body skin tactility, dyestuff and catharsis fastness (color fastness), the respect such as the elasticity, strength of cloth will consider.Because natural fiber is superior to chemical fiber in hygroscopic performance, body and skin touch and antistatic, and because knitted fabric is superior to woven fabric in elasticity, women's underwear lining fabric mostly uses natural fiber knitted fabric. In order to increase the elasticity of fabric, high elastic fabric with spandex lining is usually used.
Harmful components mainly refer to the harmful chemicals left in the dyeing process of cloth, which are easily absorbed by the skin during wearing.Hygroscopicity mainly refers to whether the human body can be effectively absorbed after sweating, long time in a state of poor hygroscopicity is easy to cause bacterial infection;Poor antistatic and skin touch, in the process of wearing will feel uncomfortable;Dye perspiration fastness, washing fastness is not good, easy to wear in the process of dye molecules fall off or even absorbed by the skin and lead to diseases;The elasticity and strength of the cloth affect its comfort and durability.
2, sticky cloth.Adhesive cloth is cloth and sponge with adhesive together, adhesive cloth surface must be smooth, and adhesive cloth can not be used in the process of harmful to human body adhesive and solvent, such as formaldehyde, acetone adhesive, otherwise, these components remaining in the fabric will affect the health of human body.Is cut.Generally, it is first typesetting and then cutting.
