[0002] Quaternary ammonium salts are commonly used antimicrobial agents in textiles, and their quality testing is crucial to ensuring their functionality and safety. Quaternary ammonium salts contain quaternary ammonium nitrogen atoms in their chemical structure, which imparts both hydrophilic and hydrophobic properties. These compounds interact strongly with various fiber materials, enhancing fabric performance. Quaternary ammonium salts effectively neutralize static charges, reducing static buildup during friction on textiles and minimizing static-induced dust absorption and clothing adhesion.

[0044] Example:

[0045] See also Figure 1 , the present invention provides a technical solution:

[0046] A method for detecting and analyzing the quality of quaternary ammonium salts in textiles, comprising the following steps:

[0047] Step 1: Cut the textile into samples and lay them flat in a sample slot. During testing, place the sample in the electrode detection area. The electrode detection area is arranged at multiple points to collect electrochemical responses at different locations of the sample, thereby improving the detection accuracy and uniformity of the overall quaternary ammonium salt content of the sample. The chemical reaction between the electrode surface and the sample surface generates an electrical signal, which is related to the quaternary ammonium salt concentration.

[0048] In the actual detection process of quaternary ammonium salt, since temperature, humidity, and ambient light can affect the detection signal, there is a deviation between it and the detection signal at room temperature, thus the concentration of the quaternary ammonium salt obtained after signal-concentration conversion according to the standard calculation formula has a certain error. The present invention collects the temperature, humidity, and ambient light in the detection process, and analyzes the influence of each factor on the electrical signal of the detection result respectively. First, the influence of temperature on the electrode reaction rate is analyzed; secondly, in combination with light intensity sensing, the concentration deviation caused by the change in light conditions is analyzed; again, the influence of humidity on the concentration of quaternary ammonium salt is analyzed;

[0049] Finally, the measurement deviation is obtained.

[0050] Step 2: Collect sample temperature data, perform correlation analysis on the temperature data, generate an electrode reaction rate index, and perform correlation analysis on the electrode reaction rate index to generate an electrochemical signal response intensity. The electrode reaction rate index is used to reflect the reaction rate of the electrode detection at the current temperature. The electrochemical signal response intensity Used to reflect the strength of the electrochemical signal at the current temperature;

[0051] The sample size is 2cm*2cm, and the temperature data The average absolute temperature of the textile surface during the test, in Kelvin, is used for temperature data. Perform correlation analysis to generate electrode reaction rate index , based on the formula:

[0052] ;

[0053] Among them, A is the frequency factor, which is used to reflect the product of the effective molecular collision frequency and the spatial orientation factor in the electrode detection reaction. The size of A is used to reflect the magnitude of the reaction rate. is the activation energy, which is used to reflect the minimum energy required for the electrode detection reaction, R is the gas constant, , electrode reaction rate index Used to reflect the absolute temperature The electrode reaction rate exponent is derived from the Arrhenius equation and reflects the relationship between chemical reaction rate and temperature. The electrode reaction rate exponent accelerates with increasing temperature, and an exponential decay term is introduced to describe this relationship.

[0054] The above formula adopts the Arrhenius equation in chemical reaction kinetics to describe the relationship between reaction rate and temperature during electrode detection.

[0055] Counter electrode reaction rate index Perform correlation analysis to generate electrochemical signal response intensity , based on the formula:

[0056] ;

[0057] in, The absolute temperature at room temperature is set to 25 degrees Celsius. The absolute temperature is The electrode reaction rate at absolute temperature is The electrode reaction rate is compared with the electrochemical signal response intensity. Used to reflect the absolute temperature The greater the value of the electrochemical signal intensity, the greater the absolute temperature. The electrode reaction rate and absolute temperature are The greater the difference, the electrode reaction rate is proportional to the strength of the electrochemical signal. The greater the deviation of the electrochemical signal intensity, the greater the degree of measurement deviation.

[0058] The electrochemical signal intensity is proportional to the reaction rate, so the above formula is used for analysis and calculation to obtain the electrochemical signal intensity The correction formula of , the formula reflects the absolute temperature The corrected electrochemical signal intensity at the time of measurement is used only to indicate the effect of temperature on the electrical signal.

[0059] Take the natural logarithm of the Arrhenius equation and transform the data into a linear relationship. The horizontal axis is , the vertical axis is , at different temperatures Determine the rate of chemical reaction during electrode detection ,draw The image of , set the intercept to b, the slope to m, and the fitting to generate b. The frequency factor A is based on the formula: .

[0060] Table 1 is The statistical data table is fitted by the data in Table 1 and the intercept is obtained. The frequency factor A is generated by the intercept. The fitting image is referenced Figure 3 , the horizontal axis is , the vertical axis is , the fitted intercept is b, through The value of A can be calculated.

[0063] Step 3: Collect sample light intensity , the light intensity of the sample Perform correlation analysis to generate salt concentration variation, perform correlation analysis on salt concentration variation to generate light salt concentration deviation ;

[0064] A light intensity sensor is set at the sample. During the detection process, the light intensity at the tth second is detected by the light intensity sensor. , for light intensity Perform correlation analysis to generate photodegradation rate , based on the formula: ,in, is the photodegradation coefficient, which is used to reflect the unit degradation rate of quaternary ammonium salt under light. This parameter reflects the average degradation rate of quaternary ammonium salts during the test. S represents the test time, and t is used to index the test time in seconds. The correlation between the photodegradation rate and light intensity reflects the degradation behavior of quaternary ammonium salts under illumination. The time-averaged light intensity more accurately reflects the effect of illumination on the photodegradation rate.

[0065] Photodegradation rate Perform correlation analysis to generate salt concentration changes , based on the formula:

[0066] ;

[0067] Salt concentration change is the estimated value of the quaternary ammonium salt concentration after the light effect. The photodegradation reaction of quaternary ammonium salt conforms to the first-order kinetics, that is, the degradation rate is proportional to the current concentration, and the concentration decays exponentially with time. The decay rate is determined by the ambient light intensity, reflecting the effect of photodegradation on the quaternary ammonium salt concentration. As the measurement time increases, the salt concentration change Gradually decrease.

[0068] in, is the quaternary ammonium salt concentration before detection, is the set value, and the change in salt concentration Perform correlation analysis to generate light salt concentration deviation , based on the formula: . Indicates elapsed time The relative change ratio of the quaternary ammonium salt concentration to the initial concentration reflects the concentration deviation caused by light.

[0069] Among them, through Calculating the average light intensity instead of a fixed light intensity allows the model to adapt to light intensity fluctuations in the actual measurement environment, thus enhancing the practicality and accuracy of the model.

[0070] Prepare multiple samples at different illumination time points Measure the corresponding quaternary ammonium salt concentration ,draw The linear graph of , the slope is fitted, and the fitting slope is . j is used to index the sampling time point.

[0071] Step 4: Collect the relative humidity H and set the water dilution coefficient and moisture absorption coefficient The water dilution coefficient is used to reflect the relative dilution effect of the unit water increase on the quaternary ammonium salt concentration in the sample, and the moisture absorption coefficient is used to reflect the quaternary ammonium salt signal change coefficient caused by the unit relative humidity change. The water dilution coefficient, moisture absorption coefficient and ambient relative humidity are correlated and analyzed to generate the humidity salt concentration deviation degree. ;

[0072] The hygroscopic coefficient reflects the change ratio of the electrochemical detection signal due to water adsorption when the humidity increases. It is used to reflect the linear change coefficient of the signal intensity per unit change of relative humidity.

[0073] Specifically obtained through the following methods:

[0074] Take several textile samples containing known concentrations of quaternary ammonium salts to ensure uniform concentrations. Use a constant temperature and humidity chamber to adjust the relative humidity of the environment and test at multiple humidity points, such as from 10% to 90% RH, with intervals of 10% RH. Under each humidity condition, measure the electrochemical signal ; Plot electrochemical signals The relationship curve between humidity points RH. The slope is output by least square fitting, and the slope is the moisture absorption coefficient. .

[0075] The moisture dilution coefficient is used to reflect the ratio of the effective concentration of quaternary ammonium salt to be "diluted" by moisture introduced by humidity, resulting in a decrease in the effective quaternary ammonium salt concentration;

[0076] Specifically obtained through the following methods:

[0077] At different humidity points, the textile sample is allowed to absorb water and reach equilibrium. The water mass absorbed by the textile sample at the corresponding humidity point RH is calculated by comparing it with the initial mass. The ratio of the absorbed water mass to the initial mass is defined as the water adsorption ratio. A curve of the water adsorption ratio-corresponding humidity point RH is plotted, and the slope is output by least squares fitting. This slope is the water dilution coefficient. .

[0078] Perform correlation analysis on water dilution coefficient, moisture absorption coefficient and relative humidity to generate humidity salt concentration deviation , based on the formula:

[0079] ;

[0080] in, is the effective concentration of quaternary ammonium salt under the influence of ambient relative humidity H, , and then substitute and merge to get: .

[0081] It indicates the relative change of the effective concentration of quaternary ammonium salt under the influence of environmental relative humidity relative to the initial concentration before detection, reflecting the degree of deviation of the influence of humidity on salt concentration. Reflects the increase in moisture due to humidity changes. Hygroscopic effect: As the relative humidity of the environment increases, the sample absorbs moisture, causing the moisture content to change from Increase to ; Decrease in effective concentration: The increase in water content causes the proportion of quaternary ammonium salt in the overall mass to decrease, which is manifested as a decrease in effective concentration, namely the "dilution effect"; The larger the value, the more significant the effect of moisture on concentration. The larger the value is, the more moisture will be added per unit humidity change. The increase in moisture will lead to linear dilution of concentration. The relationship between concentration and moisture is in the form of a denominator, which avoids non-physical phenomena such as negative concentration that may be caused by simple linear attenuation, and reflects the nonlinear coupling effect. The increase in humidity will lead to The absolute value of increases, showing a negative correlation. When the humidity increases, the effective concentration of the measurement result is negatively affected. Under extreme humidity conditions, it will tend to a constant value, indicating that the response of the system has reached saturation at high humidity.

[0082] Step 5: Humidity and salt concentration deviation , light salt concentration deviation and electrochemical signal response intensity Correlation analysis is performed to generate a measurement deviation, which is used to reflect the accuracy of the quaternary ammonium salt measured under the current temperature, humidity, and light conditions. The measurement deviation is compared with the threshold and the quaternary ammonium salt measurement accuracy level is output.

[0083] Humidity and salt concentration deviation , light salt concentration deviation and electrochemical signal response intensity Perform correlation analysis to generate the measurement deviation CP based on the following formula:

[0084] ;

[0085] is the relative deviation of the effective concentration of quaternary ammonium salt caused by humidity, is the relative deviation of the effective concentration of quaternary ammonium salt caused by light intensity, is the relative deviation of the effective concentration of quaternary ammonium salt caused by temperature. The larger the values ​​of the three relative deviations are, the greater the impact on the measurement deviation is, that is, 、 、 The larger the value of , the larger the measurement deviation, CP. The product structure reflects the combined impact of the three factors on the measurement result. Adding 1 to each value converts the relative deviation into a deviation factor. CP quantifies the degree of comprehensive deviation. A larger value indicates a more significant deviation.

[0086] The measurement deviation CP is used to reflect the degree of deviation of the electrical signal measurement of quaternary ammonium salt measured under the current temperature, humidity and light conditions. The threshold is set to , the threshold is The size is determined by precision. The higher the precision requirement, the higher the threshold value. The smaller the setting, the lower the accuracy requirement, and the threshold The larger the setting, the When , it means that the measurement deviation of the electrical signal of quaternary ammonium salt is large, and the output quaternary ammonium salt measurement accuracy level is level 2. At this time, the sample needs to be measured again. When , it means that the measurement deviation of the electrical signal of quaternary ammonium salt is within the measurement accuracy, and the output quaternary ammonium salt measurement accuracy level is level one. At this time, the measurement of quaternary ammonium salt is accurate.
