Description

Technical Field

[0001] This invention belongs to the field of functional textile technology, specifically relating to a textile with far-infrared and antibacterial functions, as well as its preparation method and apparatus. Background Technology

[0002] Textiles with far-infrared, magnetic, and antibacterial functions, designed to regulate and improve bodily functions without producing any toxic side effects on the human body, and thus achieving health benefits, are collectively referred to as health-functional textiles.

[0003] In the electromagnetic spectrum, infrared radiation lies between visible light and microwaves, with a wavelength range of 0.76-1000 μm. Based on wavelength, infrared radiation can be divided into near-infrared, mid-infrared, and far-infrared components, although the wavelength range varies depending on the application, without a strict dividing line. The absorption spectra of most heated organic and inorganic substances and water are in the range of 2.5-25 μm. The resonant wavelengths of hydrogen-oxygen bonds, carbon-hydrogen bonds, and carbon-oxygen bonds in human tissues also mostly fall within this range.

[0004] Human cell growth and reproduction are based on the synthesis and replication of deoxyribonucleic acid (DNA), whose double helix structure contains a large number of hydrogen bonds. The breaking and binding of these hydrogen bonds requires corresponding far-infrared photon energy. Far-infrared fabrics utilize the absorbed external energy and the heat emitted by the human body to reflect the far-infrared rays that the human body needs most.

[0005] Chinese invention patent CN102926223A discloses a method for preparing far-infrared textiles. This patent involves adding far-infrared ceramic powder to a spinning solution to prepare far-infrared fibers, and then using these fibers to prepare textiles with far-infrared functions. While this method is simple in its preparation process and operation, it can only support synthetic fiber textiles.

[0006] Chinese invention patent CN106868870A discloses a textile that emits far-infrared rays. This patent describes a process where the textile undergoes 168 hours of high-energy radiation treatment or chemical treatment to obtain a textile with negative ion far-infrared effects. However, the patent only specifies the chemical treatment method and does not specify the detailed process and method of high-energy radiation treatment. Furthermore, the chemical treatment process is cumbersome and lengthy, and the wearability of the treated textile remains to be investigated.

[0007] Therefore, it is necessary to develop a textile with far-infrared function to achieve far-infrared regulation and antibacterial function. Summary of the Invention

[0008] This invention provides a textile with health care functions and its preparation method and apparatus, which overcomes the limitations of functional chemical fibers on textile materials and the defect of textiles with a stiff hand feel after various functional finishing. This textile can achieve far-infrared function and antibacterial function.

[0009] The technical solution of this invention is as follows:

[0010] In a first aspect, a device for preparing textiles with far-infrared and antibacterial functions is provided, comprising an outer shell, an intermediate heat-insulating layer and a reflective layer arranged sequentially inside the outer shell, and a plurality of infrared light generators arranged inside the reflective layer; the infrared light generator includes an electric heat source and a radiator, the electric heat source and the radiator are pressed together, the electric heat source is connected to a power source through a switch, and the preparation device emits infrared waves with a wavelength of 2-30μm and continuously radiates infrared waves outward.

[0011] Preferably, the intermediate heat insulation layer is one of silicon material, aluminum silicate fiber, or stainless steel composite insulation board made of carbon steel and stainless steel, and the reflective layer is aluminum alloy.

[0012] Preferably, the electric heat source is one of iron-chromium-aluminum alloy, nickel-chromium alloy or titanium-germanium alloy.

[0013] Preferably, the radiator has a microbubble count of 2000-3000 per cm³. 3 Milky white quartz glass.

[0014] Secondly, a method for preparing textiles with far-infrared and antibacterial functions using the aforementioned preparation device is disclosed. The method is characterized in that the textiles are placed in the preparation device, treated at 30-70°C for 2-6 hours, and then removed to obtain textiles with far-infrared and antibacterial functions.

[0015] Preferably, the textile is a fabric or a finished product.

[0016] Preferably, the textile material is one or more of natural fibers, regenerated cellulose fibers, or synthetic fibers.

[0017] Preferably, the natural fiber is one of cotton, linen, silk or wool, the regenerated fiber is lyocell or viscose, and the synthetic fiber is one of polyester, nylon, acrylic or spandex.

[0018] Thirdly, the preparation method described above discloses textiles with far-infrared and antibacterial functions.

[0019] This invention utilizes the absorption of infrared light by textile materials within the 2-30μm range. When the vibrational frequency of the textile material molecules is the same as the frequency of the radiated light, and the dipole moment of the molecules changes during vibration, resonance can occur, causing energy level transitions in the molecules and absorbing radiant energy. Through prolonged irradiation with infrared light, the textile material absorbs infrared light and converts it into the internal energy of the textile, thus acquiring far-infrared and antibacterial functions.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] The device and method of this invention produce textiles with multiple health-care functions that are not limited by textile materials and avoid the problem of stiffness caused by multiple functional finishing processes. This reduces the use of auxiliaries in the dyeing and finishing process, lowers energy consumption throughout the process, reduces the pressure on wastewater treatment, and reduces environmental costs.

An intermediate heat insulation layer 3 and a reflective layer 2 are sequentially arranged inside the outer shell 4. An infrared light generator 1 is arranged inside the reflective layer 2. The infrared light generator 1 includes an electric heat source and a radiator, which are pressed together. The electric heat source is connected to a power source through a switch. The switch is equipped with a temperature sensor that cuts off the power when the temperature is too high and is also equipped with a leakage current protection device that disconnects the circuit in time when leakage occurs. The fabrication device emits infrared waves with a wavelength of 2-30μm and continuously radiates infrared waves outward.

The number of microbubbles passing through the radiator is 3000 / cm². 3 The milky white quartz glass reflects infrared light with a wavelength in the range of 2-30μm.

After being reflected by the radiator, it forms infrared light with wavelengths in the range of 2-30μm. The electric heat source and the radiator are processed into an infrared light generator 1 with a thickness of 25mm. The infrared light generator 1 is placed in a box with an inner wall made entirely of aluminum alloy as a reflective layer 2.
