Description

Technical Field

[0001] The invention belongs to the field of polyester-spandex fabrics, and in particular relates to a highly moisture-permeable polyester-spandex fabric. Background Art

[0002] Polyester is a synthetic fiber, lacking hydrophilic groups in its molecular structure, so it has poor water absorption and is a typical hydrophobic fiber. However, polyester fiber has many characteristics such as high modulus, high strength and good shaping, and is widely used in clothing and home products. In view of the poor hydrophilicity of polyester fabrics, people have hydrophilic finishing of polyester fabrics. At present, the market mostly chooses polyester polyether hydrophilic finishing agents. This type of finishing agent has a certain hydrophilic and hygroscopic finishing effect through padding and baking at 170℃. For ordinary dark polyester fabrics, usually after functional finishing, reduction cleaning can improve the color fastness to level 4. However, for polyester spandex fabrics, high-temperature pre-setting at more than 190℃ has been done before dyeing, and reduction cleaning has been done in the cylinder at 80℃ for 10 minutes after dyeing, and then the finishing agent is padded at 150℃ and baked.
