The fineness of the spandex filament is 60 dtex, and the fiber specification of the cotton fiber layer is 3 dtex x 60 mm. A high-temperature resistant layer is arranged between the cotton fiber layer and the spandex filament yarn core. A flame-retardant layer is arranged between the high-temperature resistant layer and the cotton fiber layer. The high-temperature resistant layer is a polyethylene layer, and a moisture-absorbing and sweat-wicking yarn is further arranged outside the cotton fiber layer. The spandex core spun yarn provided by the technical solution ensures the excellent elasticity of the core spun yarn, and the fabric woven therefrom has natural wrinkle-resistant properties, and the formed fabric has comfortable, breathable, moisture-absorbing, and aesthetically pleasing wearing performance.

[0004] CN112210859A discloses a stock solution colored core spun yarn and a preparation process thereof. The stock solution colored core spun yarn comprises a core yarn and a wrapping yarn. The wrapping yarn is arranged outside the core yarn. The core yarn is spandex fiber. The wrapping yarn is composed of 60%-70% polyester fiber and 40%-30% viscose fiber.

[0066] (4) Anti-ultraviolet ability test: The transmittance of ultraviolet light with a wavelength of 280-400 nm is measured using a spectrophotometer, and the ultraviolet shielding rate is calculated.

[0067] (5) Heat shielding property test: According to “JIS L1951 Evaluation method for thermal insulation of fabrics”, a heat source is used to irradiate the sweat-concealing fabric or the fabric to be tested for 30 min, and a thermal imaging instrument is used to measure the temperature change of the heat energy after the heat source transmits through the sample, and the heat shielding rate (%) is calculated.
