Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, fig. 1 is a method for preparing an antibacterial and bacteriostatic textile according to some embodiments of the present application, including the steps of:
s1, irradiating the textile for a preset time by using far infrared radiation with preset space power density at a preset environmental temperature so as to improve the far infrared emissivity of the textile to be not less than a preset emissivity threshold value; the spatial power density is the far infrared radiation emission power per unit volume of the irradiated space.
In fact, the far infrared radiation has a thermal effect and a characteristic absorption effect, and can cause the microorganisms to change such as protein denaturation, enzyme inactivation, DNA change and the like, so that the normal physiological metabolism of the microorganisms is seriously interfered, and the proliferation capacity of the microorganisms is reduced. The method utilizes far infrared radiation to irradiate the textile, and can enable electrons of atoms in the textile to jump based on a far infrared light wave resonance absorption principle, thereby changing the infrared radiation characteristic of the textile, improving the far infrared emissivity of the textile, and further enabling the textile to have stable antibacterial and bacteriostatic effects. In addition, the far infrared radiation can restrain the mite and grow, after the far infrared emissivity of fabrics self improves, can restrain the mite on the one hand and grow and breed on the fabrics, on the other hand has the effect of keeping away to the mite on the fabrics to be favorable to improving the mite prevention performance of fabrics.
It should be noted that, the method for treating the textile does not change the original mechanical property and processability of the textile, so that the method can maintain the original mechanical property and processability of the textile while improving the antibacterial and bacteriostatic properties and the anti-mite property of the textile, and avoid the reduction of the mechanical property and processability of the textile, and has good practical value.
Preferably, the wavelength of the far infrared radiation is from 2 μm to 25 μm. Far infrared radiation in the wavelength range has a relatively superior antibacterial and bacteriostatic effect, and the textile is irradiated by the far infrared radiation in the wavelength range so as to improve the far infrared emissivity of the textile, so that the wavelength of the far infrared radiation radiated by the textile is mainly concentrated in the wavelength range, and the textile has the relatively superior antibacterial and bacteriostatic effect. Further preferably, the wavelength of the far infrared radiation is 8-14 μm, and tests prove that the obtained textile has the optimal antibacterial and bacteriostatic effects in the wavelength range under the same other conditions.
Wherein, the far infrared emissivity of fabrics self is high more, then its antibiotic antibacterial effect is better, after improving the far infrared emissivity of fabrics to a certain extent, will further improve far infrared emissivity, every improvement unit far infrared emissivity, will need to pay out bigger cost (if need longer irradiation time, thereby consume more electric energy), here, set up a threshold value, reach this threshold value when the far infrared emissivity of fabrics self, just stop shining, thereby when guaranteeing that the fabrics has sufficient antibiotic antibacterial property, avoid the treatment effeciency low excessively, electric energy consumption is too big.
Preferably, the preset emissivity threshold is 0.9. When the far infrared emissivity of the textile is not less than 0.9, the textile has strong antibacterial and bacteriostatic effects, the repelling rate to mites is high, the anti-mite performance is good, and when the far infrared emissivity exceeds 0.9, the cost required for increasing the unit far infrared emissivity can be increased rapidly, and when the far infrared emissivity reaches 0.9, the irradiation can be stopped, so that the problems of low treatment efficiency and excessive power consumption are avoided.
Preferably, the preset ambient temperature is 40 ℃ to 55 ℃. If the environmental temperature is too high, the textile is easy to age, and if the environmental temperature is too low, the far infrared emissivity of the textile can be improved to be not less than a preset emissivity threshold value only by needing longer irradiation time, the treatment efficiency is lower, within 40-55 ℃, the textile can be prevented from aging, and the treatment efficiency can be ensured to be higher. Further preferably, the preset ambient temperature is 50 ℃.
Usually, can shine the processing to the fabrics in inclosed irradiation space, so that the ambient temperature is controlled, utilize the inside irradiation case that is provided with the far infrared radiation source of use to shine the processing, this irradiation case still is provided with air circulation system in order to guarantee that inside ambient temperature is even, and when the fabrics rose because of absorbing far infrared radiation, the mobile air that air circulation system produced can cool down the fabrics, thereby avoid the high temperature of fabrics itself, in this certain space of irradiation case, through adjusting the total emission power of far infrared radiation source (generally, the radiation source is provided with a plurality ofly, the power of every radiation source is the same, the sum of the emission power of all radiation sources is this total emission power) adjustable space power density. Experiments have shown that for most textiles, the spatial power density is set to 180W/m when the wavelength of the far infrared radiation is 2-25 μm and the ambient temperature is 40-55 deg.C 3 -210W/m 3 The far infrared emissivity of the textile can be guaranteed to be improved to be more than 0.9 in a short time, the textile can be guaranteed not to be heated too fast due to overlarge space power density, and the problem that the temperature of the textile is too high (the textile is aged due to the fact that the textile is too high due to the fact that the heat of the textile cannot be taken away by circulating airflow in the irradiation box is avoided. Preferably, the preset space power density is 200W/m 3 Not only can improve the treatment efficiency, but also can avoid the problem that the textile cannot be cooled in time due to too fast temperature rise so as to cause the aging of the textile.
For example, in some embodiments, an internal space of 5 m is utilized 3 The irradiation box is used for treating the textile to reach 200W/m 3 Spatial power density of the required total emission of the infrared sourceThe power is set to 1000W, and thus, step S1 includes:
at 5 m 3 In the closed irradiation space, under the preset environmental temperature, the textile is irradiated by 1000W of far infrared radiation for a preset time so as to improve the far infrared emissivity of the textile to be not less than a preset emissivity threshold value.
Based on the environmental temperature and the spatial power density, the far infrared emissivity of the textile can be increased to be above 0.9 by irradiating the textile for 1.8 to 2.5 hours. Therefore, in this embodiment, the predetermined time is 1.8 hours to 2.5 hours. Preferably, the preset time is 2 hours.
In some embodiments, referring to fig. 2, after step S1, the method further comprises the steps of:
s2, cooling the textile;
s3, detecting the far infrared emissivity of the textile;
and S4, if the far infrared emissivity of the textile does not reach a preset emissivity threshold value, performing supplementary irradiation treatment on the textile.
Wherein, the textile can be cooled naturally or by an air cooling mode.
Wherein, the far infrared emissivity of the textile can be detected by adopting the existing detection method (for example, but not limited to, the far infrared performance detection method specified in the standard GB/T30127-2013).
The emissivity deviation (namely the difference between the preset emissivity threshold value and the measured value of the far infrared emissivity of the textile) can be calculated, the complementary irradiation processing time can be calculated according to the emissivity deviation, and then the complementary irradiation processing can be carried out on the textile according to the complementary irradiation processing time.
For example, the irradiation time required for complementary irradiation of textiles of the same type at a preset ambient temperature to make the far infrared emissivity of the textiles reach a preset emissivity threshold can be measured in advance through tests under the condition of different emissivity deviations, so as to fit a calculation formula between the complementary irradiation processing time and the emissivity deviation (hereinafter referred to as a complementary irradiation processing time calculation formula), in step S4, the emissivity deviation between the preset emissivity threshold and the measured value of the far infrared emissivity of the textiles is calculated, then the emissivity deviation is substituted into the complementary irradiation processing time calculation formula, the complementary irradiation processing time is calculated, and finally, the textiles are irradiated again according to the calculated complementary irradiation processing time at the preset ambient temperature.
Or for example, a plurality of emissivity deviation ranges can be divided in advance, and the minimum irradiation time required for the far infrared emissivity of the textiles of the same type after the complementary irradiation treatment is not lower than the preset emissivity threshold value at the preset environmental temperature can be determined through tests in each emissivity deviation range, and a complementary irradiation treatment time query table (which records each emissivity deviation range and the corresponding minimum irradiation time) is formed, in step S4, the emissivity deviation between the preset emissivity threshold value and the measured value of the far infrared emissivity of the textiles is calculated first, then the corresponding minimum irradiation time is obtained by querying in the complementary irradiation treatment time query table according to the emissivity deviation range where the emissivity deviation is located, and is used as the complementary irradiation treatment time, and finally the textiles are irradiated again according to the queried complementary irradiation treatment time at the preset environmental temperature.
