[0025] In this embodiment, the moisture-wicking substrate 1 is made of ultra-fine denier modal fiber and carbonized bamboo fiber through vortex spinning process to form a honeycomb moisture-wicking channel. The honeycomb moisture-wicking channel has a pore size of 0.6-1.2 mm, and the surface is formed by plasma etching to form a groove structure with a depth of 2-3 μm. The fineness of the ultra-fine denier modal fiber is 0.8 dtex, and the thickness of the moisture-wicking substrate 1 is 2.0 mm.
[0026] In this embodiment, the gradient insulation layer 2 has a thickness of 3.0 mm. The gradient insulation layer 2 is constructed from hollow polyester fibers woven in three dimensions to form a three-dimensional honeycomb structure. The hollowness of the hollow polyester fibers is 85%, the pore size of the three-dimensional honeycomb matrix is 0.8-1.5 mm, and the thickness is 2.5 mm. Far-infrared ceramic powder and phase change microcapsules are blended in a 2:1 ratio and injected into the honeycomb pores of the three-dimensional honeycomb matrix using a vacuum filling device. The particle size of the far-infrared ceramic powder is ≤5 μm, the core material of the phase change microcapsules is octadecane, the wall material is melamine resin, and the filling density is ≥75%. The honeycomb structure retains static air and allows for far-infrared radiation temperature rise, thus improving the fabric's warmth retention.

The nano-silver-loaded acrylic fibers have a diameter of 15±2 μm. The polyester fibers are coated with a quaternary ammonium salt antibacterial agent via melt blending, with a loading of 1.2 wt%.

To prepare the antibacterial functional layer, silver-loaded acrylic masterbatch with a silver content of 800 ppm and modified polyester chips containing 3% quaternary ammonium salt are blended and spun using a twin-screw extruder, and then woven on a 12-needle double-sided circular knitting machine with a basis weight of 110 g / m². 2 The double rib knit fabric utilizes a synergistic mechanism of quaternary ammonium salt slow release and nano-silver contact sterilization to enhance the fabric's antibacterial and bacteriostatic effects.
[0028] In this embodiment, the moisture-wicking base layer 1 and the gradient insulation layer 2 form a continuous serpentine joint through an ultrasonic-hot-press composite process. The width of the serpentine joint is 1.2 mm, the amplitude is 50 μm, the pressure is 0.5 MPa, and the tensile breaking strength of the joint is ≥200 N.
