Description

Technical Field

[0001] The present invention relates to the technical field of fabric performance detection, and in particular to a method, system and device for controlling the performance of flame-retardant fiber fabrics. Background Art

[0002] Flame-retardant fiber fabrics, as specialized protective textile materials, are widely used in high-heat-risk environments, such as firefighting, military and police work, and power generation. Existing flame-retardant performance evaluation methods are mostly based on standard test conditions, such as vertical combustion and limiting oxygen index, and focus on structured testing of the fabric's physical properties and thermal response.

[0003] For example, the invention with the announcement number CN118566253A discloses a comprehensive performance testing device and method for electrothermal cotton composite home textile fabrics, comprising a frame, wherein the left and right sides of the top of the frame are fixedly connected to support members, and the interior of the support members is fixedly connected to a fixing plate. The present invention is provided with a first telescopic mechanism and a second telescopic mechanism for coordinated use, so that four sets of clamping mechanisms can clamp the four corners of the home textile fabric respectively to fix the home textile fabric, and can also stretch the fixed home textile fabric in the transverse direction by contracting the first telescopic mechanism on both sides, thereby determining the tensile strength of the home textile fabric in the transverse direction, and can also stretch the fixed home textile fabric in the longitudinal direction by contracting the second telescopic mechanism, thereby determining the tensile strength of the home textile fabric in the longitudinal direction. Secondly, by cooperating with the transverse motion mechanism, the vertical motion mechanism and the longitudinal motion mechanism, the wear resistance and flame retardancy of the home textile fabric can be determined.

[0004] However, the traditional technical testing process ignores the structural changes of the fabric under actual wearing conditions and the interference of the humid and hot environment, such as wrinkle accumulation, strain deformation, moisture content fluctuations, etc. This leads to obvious deviations between the evaluation results and the actual flame retardant behavior in the wearing scenario, making it difficult to accurately support the judgment of protection capabilities under high-risk working conditions.

[0005] Therefore, in order to solve the above problems, there is an urgent need for a method, system and device for controlling the performance of flame retardant fiber fabrics. Summary of the Invention

[0006] Technical problems solved

[0007] In response to the deficiencies of the prior art, the present invention provides a method, system and device for controlling the performance of flame-retardant fiber fabrics, which solves the problem of flame-retardant evaluation distortion caused by the disconnection between standard testing and actual wearing conditions.

[0008] Technical Solution

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: a performance control method, system and device for flame-retardant fiber fabrics, comprising the following steps: S1, acquiring flame-retardant fabric wearing status data through collaborative collection of an integrated multimodal fabric sensing device and a thermal, moisture and force sensing network, and preprocessing the flame-retardant fabric wearing status data; S2, analyzing the unit thermal drive temperature response capability of the fabric in the wearing state based on the flame-retardant fabric wearing data after grid binding preprocessing, and performing combustion trigger judgment; S3, extracting the ignition time according to the combustion judgment result, quantifying the ignition deviation between the standard test and the wearing state, and correcting the temperature rise path of the test distortion grid to generate a wearing flame-retardant performance response data set; S4, retrieving the wearing flame-retardant performance response data set, evaluating the distortion risk degree of the standard test in the wearing state, determining the dominant distortion source and performing response compensation, and outputting a credibility label and correction path covering the entire domain.

[0010] Furthermore, the specific steps of acquiring the flame retardant fabric wearing state data by collaboratively collecting data through an integrated multimodal fabric sensing device and a thermal, moisture and force sensing network, and preprocessing the flame retardant fabric wearing state data are as follows: collaboratively collecting data through an integrated multimodal fabric sensing device and a thermal, moisture and force sensing network, respectively deploying temperature and humidity sensors, heat flux meters, strain gauges and fabric surface geometry recognition components, continuously recording the heat input, structural deformation and environmental interaction state of the flame retardant fabric during wearing, and acquiring the flame retardant fabric wearing state data, which includes fabric moisture content, surface temperature, heat flux density, wrinkle angle, surface tensile strain, specific heat capacity and latent heat of evaporation; The structured grid interpolation algorithm is used to reconstruct and fill the spatial missing areas in the flame-retardant fabric wearing data, repairing the structural information loss problem caused by fabric wrinkle occlusion, measurement point detachment and sensor failure; the flame-retardant fabric wearing data is smoothed in the time dimension by a double-window sliding average smoothing algorithm, reducing the short-term temperature and heat flux fluctuations caused by environmental disturbances and dynamic movements; the outliers in the flame-retardant fabric wearing data are identified by a shear compression combined with anomaly detection algorithm, eliminating strain anomalies caused by unnatural movements or extreme measurement point deformation; the flame-retardant fabric wearing data is converted to a standard scale by a maximum-minimum normalization algorithm to achieve normalization of the flame-retardant fabric wearing data.

[0011] Furthermore, based on the flame-retardant fabric wearing data after grid binding preprocessing, the specific steps of analyzing the unit heat-driven temperature response ability of the fabric in the wearing state are as follows: map the preprocessed flame-retardant fabric wearing data to the two-dimensional grid area, construct the physical input field of the simulation domain, and bind each grid to a set of measured flame-retardant fabric wearing data; take each grid as the unit, analyze the unit heat-driven temperature response ability of the fabric in the wearing state: divide the heat flux density by the specific heat capacity as the unit temperature rise benchmark item; divide the product of the fabric moisture content and the latent heat of evaporation by the product of the specific heat capacity and the surface temperature, and then subtract this ratio from one as the moisture buffer ratio item; divide the pleat angle by 90 to characterize the change ratio of the effective heated area of ​​the fabric surface, and subtract this change ratio from one as the heat shielding adjustment item; multiply the unit temperature rise benchmark item, the moisture buffer ratio item and the heat shielding adjustment item to obtain the temperature rise response evaluation value.

[0012] Furthermore, the specific steps for executing combustion trigger judgment are as follows: compare the temperature rise response evaluation value of each grid with the temperature rise response threshold in real time, and implement a partitioned asynchronous thermal response strategy: mark the grid cells with temperature rise response evaluation values ​​higher than the temperature rise response threshold as potential high-risk areas, and assign a smaller temperature rise response time step; mark the grids with temperature rise response evaluation values ​​lower than the temperature rise response threshold as low-response areas, and assign a standard time step; use the response label and surface temperature of the grid as the joint triggering conditions for flame spread: the potential high-risk area is judged to be in a combustion state if the surface temperature exceeds the combustion judgment threshold at any time; the low-response area enters a combustion state only when the surface temperature continues to be higher than the combustion judgment threshold for three consecutive combustion judgment cycles.

[0013] Furthermore, the specific steps for extracting the ignition time based on the combustion judgment results and quantifying the ignition deviation between the standard test and the wearing state are as follows: after completing the combustion judgment in the wearing state, track the temperature change process of each grid, and take the time step when the surface temperature first reaches the combustion judgment threshold as the ignition time of the grid in the wearing state; synchronously run the thermal diffusion process of the corresponding grid under the standard conditions of the fabric being flat, dry and strain-free to extract the standard ignition time; subtract the standard ignition time from the ignition time in the wearing state and multiply it by the temperature rise response evaluation value to obtain the ignition response offset term; divide the fabric moisture content by the fabric moisture content plus one, and then subtract this ratio from 1 to obtain the moisture suppression term; multiply the heat flux density, heat shielding adjustment term and moisture suppression term to obtain the comprehensive heat input attenuation term; divide the ignition response offset term by the comprehensive heat input attenuation term to obtain the ignition offset evaluation value.

[0014] Furthermore, the specific steps for correcting the temperature rise path of the test distorted grid and generating a wearing flame retardant performance response data set are as follows: comparing the ignition offset evaluation value with the ignition offset threshold: if the biased ignition offset evaluation value is less than the ignition offset threshold, the grid test result is judged to be credible, marked as a credible area, and its original evaluation path is retained; if the biased ignition offset evaluation value is greater than or equal to the ignition offset threshold, the grid test result is judged to be distorted, and the fabric moisture content, fold angle and surface tensile strain of the grid are extracted and fed back as biasing factors to the correction path of the temperature rise response evaluation value, and the temperature rise response evaluation value is recalculated; then the wearing state ignition time and ignition offset evaluation value of the grid are updated; the evaluation data of the grid that has completed the correction calculation are unified and integrated, and the evaluation data include the temperature rise response evaluation value, the wearing state ignition time and the ignition offset evaluation value to form a wearing flame retardant performance response data set covering the entire domain.

[0015] Furthermore, the specific steps of retrieving the flame retardant performance response data set for wearing and evaluating the degree of distortion risk of the standard test in the wearing state are as follows: Retrieve the flame retardant performance response data set for wearing, and analyze the degree of distortion risk of the standard test in the wearing state based on the temperature rise response evaluation value and the flame retardant fabric wearing data: divide the temperature rise response evaluation value by the heat flux density as the thermal response intensity normalization item; divide the product of the fabric moisture content and the latent heat of evaporation by the product of the specific heat capacity and the surface temperature as the moisture-heat buffer item; convert the wrinkle angle into radians and take the sine value as the thermal shielding nonlinear interference item; add the moisture-heat buffer item, surface tensile strain and shielding nonlinear interference item as the wearing evaluation interference item; multiply the thermal response intensity normalization item by the wearing evaluation interference item to obtain the standard test distortion evaluation value.

[0016] Furthermore, the specific steps of determining the dominant distortion source and performing response compensation, and outputting the credibility label and correction path covering the entire domain are as follows: comparing the standard test distortion evaluation value with the test distortion threshold, and establishing an evaluation credibility classification strategy: if the standard test distortion evaluation value is less than the test distortion threshold, and the corresponding temperature rise response evaluation value is lower than the temperature rise response threshold, then the grid is determined to be a standard evaluation credibility area, and its original test path is retained; otherwise, the grid is determined to be an evaluation distortion risk area; for the grid in the evaluation distortion risk area, the proportion of moisture and heat buffer items, shielding interference items, and tensile strain items in the wearing evaluation interference items is analyzed to determine the dominant distortion source and select the corresponding compensation modeling path: if the moisture and heat buffer item is dominant, the temperature rise response time step is dynamically increased according to the moisture content of the fabric, and the grid is delayed from entering the combustion judgment state to simulate the flame suppression effect in the wet area; if the shielding interference item is dominant, the heat flux of the grid is reconstructed. Density distribution, correct the effective heated area based on the fold angle, and replace the uniform input assumption under the standard state; if the tensile strain term is dominant, dynamically reduce the temperature rise response step and the spread propagation path according to the surface tensile strain, simulate the influence of the structural tension change caused by the strain on the heat conduction rate and the flame advancement direction, and give priority to the high strain area in the temperature rise judgment window; integrate the grid response results of the standard evaluation credible area and the evaluation distortion risk area, update the wearing flame retardant performance response data set, and bind each grid to the temperature rise response evaluation value, ignition offset evaluation value, standard test distortion evaluation value, evaluation status label, dominant component of the wearing evaluation interference item, adjusted temperature rise response time step and combustion judgment trigger mode; use the wearing flame retardant performance response data set to mark the blind area covered by the standard test, and replace the original evaluation path of the distorted area to form a response judgment and path correction closed loop for the real wearing state.

[0017] According to a second aspect of the present invention, a performance control system for flame-retardant fiber fabrics is provided, comprising: a flame-retardant fabric wearing data collection and preprocessing module, a temperature rise response evaluation and combustion judgment module, a response feature fusion and offset identification module, and an evaluation credibility reconstruction and response output module, wherein: the flame-retardant fabric wearing data collection and preprocessing module is used to obtain flame-retardant fabric wearing state data through collaborative collection of an integrated multimodal fabric sensing device and a thermal, moisture and force sensing network, and preprocess the flame-retardant fabric wearing state data; the temperature rise response simulation and combustion judgment module is used to analyze the unit heat-driven temperature response capability of the fabric in the wearing state based on the flame-retardant fabric wearing data after grid binding preprocessing, and perform combustion trigger judgment; the response feature fusion and offset identification module is used to extract the ignition time based on the combustion judgment result, quantify the ignition deviation between the standard test and the wearing state, and correct the temperature rise path of the test distortion grid to generate a wearing flame-retardant performance response data set; the evaluation credibility reconstruction and response output module is used to retrieve the wearing flame-retardant performance response data set, evaluate the distortion risk level of the standard test in the wearing state, determine the dominant distortion source and perform response compensation, and output a credibility label and correction path covering the entire domain.

[0018] The third aspect of the present invention provides a performance control device for flame-retardant fiber fabrics, comprising: a state perception integrator, a thermal drive response analyzer, an ignition offset quantizer, and an adaptability evaluation compensator, wherein: the state perception integrator is used to complete the collection, processing, and structural mapping of multi-source physical data under the wearing state of the fabric; the thermal drive response analyzer is used to analyze the temperature rise behavior under the action of heat input and identify potential high-risk areas for spread; the ignition offset quantizer is used to evaluate the response offset under standard and wearing conditions and perform path correction; the adaptability evaluation compensator is used to determine the evaluation distortion area and implement a response compensation strategy dominated by the wearing factor.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 4, an embodiment of the present invention provides a technical solution: a performance control method, system and device for flame-retardant fiber fabrics, comprising the following steps: S1, acquiring flame-retardant fabric wearing status data through collaborative collection of an integrated multimodal fabric sensing device and a thermal, moisture and force sensing network, and preprocessing the flame-retardant fabric wearing status data; S2, analyzing the unit heat-driven temperature response capability of the fabric in the wearing state based on the flame-retardant fabric wearing data after grid binding preprocessing, and performing combustion trigger judgment; S3, extracting the ignition time according to the combustion judgment result, quantifying the ignition deviation between the standard test and the wearing state, and correcting the temperature rise path of the test distortion grid to generate a wearing flame-retardant performance response data set; S4, retrieving the wearing flame-retardant performance response data set, evaluating the distortion risk degree of the standard test in the wearing state, determining the dominant distortion source and performing response compensation, and outputting a credibility label and correction path covering the entire domain.

[0031] Specifically, the flame retardant fabric wearing state data is obtained by integrating a multimodal fabric sensing device and a thermal, moisture and force sensing network, and the specific steps of preprocessing the flame retardant fabric wearing state data are as follows: by integrating a multimodal fabric sensing device and a thermal, moisture and force sensing network, respectively, temperature and humidity sensors, heat flux meters, strain gauges and fabric surface geometry recognition components are deployed to continuously record the heat input, structural deformation and environmental interaction state of the flame retardant fabric during the wearing process, and obtain the flame retardant fabric wearing state data. The flame retardant fabric wearing data includes fabric moisture content, surface temperature, heat flux density, fold angle, surface Surface tensile strain, specific heat capacity, and latent heat of evaporation; among them, the moisture content of the fabric is obtained through a fabric-embedded micro-humidity sensor; the surface temperature is obtained through a high-precision surface infrared temperature measuring element; the heat flux density is obtained through a fabric surface heat flux meter; the wrinkle angle is extracted through a surface morphology visual recognition component; by arranging high-sensitivity resistance strain gauges in areas prone to deformation on the fabric surface, the degree of tensile deformation of the fabric when worn is monitored in real time, and the surface tensile strain value is obtained; the specific heat capacity is obtained by matching the actual material of the fabric through the material specific heat capacity parameter database; the latent heat of evaporation is obtained through the linkage measurement of fabric component analysis and thermal analysis equipment. Then, the spatial missing areas in the flame-retardant fabric wearing data are reconstructed and filled through the structural grid interpolation algorithm, repairing the structural information loss problem caused by fabric wrinkle occlusion, measurement point detachment and sensor failure; the flame-retardant fabric wearing data is smoothed in the time dimension through the double-window sliding average smoothing algorithm, reducing the short-term temperature and heat flux fluctuations caused by environmental disturbances and dynamic movements; the outliers in the flame-retardant fabric wearing data are identified through the shear compression combined with the anomaly detection algorithm, and the strain anomalies caused by unnatural movements or extreme measurement point deformation are eliminated; the flame-retardant fabric wearing data is converted to a standard scale through the maximum and minimum normalization algorithm to achieve the normalization of the flame-retardant fabric wearing data.

[0032] In this implementation, a multimodal fabric sensing device is coordinated with a thermal, moisture, and force sensing network to independently extract moisture content, surface temperature, heat flux density, wrinkle angle, surface tensile strain, specific heat capacity, and latent heat of evaporation from flame-retardant fabric wearing state data, ensuring that each physical quantity has a clear measurement source and physical unit basis. Furthermore, through a structured grid interpolation, sliding average smoothing, combined anomaly detection, and normalization process, the data is preprocessed to ensure spatial integrity, temporal stability, data reliability, and scale uniformity. This provides accurate and stable physical input support for subsequent thermal response modeling and regional assessment mechanisms based on measured input.

[0033] Specifically, based on the flame-retardant fabric wearing data after grid binding pretreatment, the specific steps of analyzing the unit heat-driven temperature response ability of the fabric in the wearing state are as follows: map the pretreated flame-retardant fabric wearing data to the two-dimensional grid area, construct the physical input field of the simulation domain, and bind each grid to a set of measured flame-retardant fabric wearing data, including fabric moisture content, surface temperature, heat flux density, fold angle, surface tensile strain, specific heat capacity and latent heat of evaporation; take each grid as a unit, analyze the unit heat-driven temperature response ability of the fabric in the wearing state: divide the heat flux density by the specific heat capacity, and extract it as the benchmark item of the heating ability under unit heat input conditions; divide the fabric moisture content by the evaporation The product term of latent heat is used as a characterizing factor of the moisture and heat buffering capacity of the fabric, and then divided by the product of specific heat and surface temperature. The calculated result is used as the moisture and heat buffer proportion term, which reflects the delayed inhibition effect of local moisture content in the fabric on the thermal response process; the fold angle is divided by 90 to extract the influence of the geometric shielding degree of the fabric surface on the directional disturbance of heat input, and further used as the heat shielding adjustment term minus the angle ratio to correct the effective heated area of ​​local non-flat areas; the unit temperature rise benchmark term, the moisture and heat buffer proportion term and the heat shielding adjustment term are multiplied to obtain the temperature rise response evaluation value after comprehensively considering the heat input intensity, moisture suppression effect and structural shielding characteristics.

[0034] The specific calculation formula for the temperature rise response evaluation value is:

[0035] ;

[0036] Where S represents the temperature rise response evaluation value, Q represents the heat flux density, C represents the specific heat capacity, W represents the moisture content of the fabric, L represents the latent heat of evaporation, and D represents the surface temperature. Indicates the fold angle.

[0037] In this embodiment, Table 1 is a temperature rise response evaluation value data table, listing the measured input parameters and corresponding temperature rise response evaluation value calculation results for five grids in the wearing state. The variables included in the data table include heat flux density, specific heat capacity, fabric moisture content, latent heat of evaporation, surface temperature, pleat angle, and the final calculated temperature rise response evaluation value. For grid C1, the heat flux density is 20.62, the specific heat capacity is 1.378, the fabric moisture content is 0.152, the latent heat of evaporation is 2250, the surface temperature is 321.0, and the pleat angle is 48.4. The calculated temperature rise response evaluation value is 3.56. For grid C2, the heat flux density is 29.26, the specific heat capacity is 1.329, the fabric moisture content is 0.076, the latent heat of evaporation is 2250, the surface temperature is 328.3, and the pleat angle is 34.2.

[0038] Table 1 Temperature rise response evaluation value data table

[0039]

[0040] like Figure 3 The figure shows the temperature rise response evaluation value and threshold analysis diagram of the simulated grid. The figure shows the changes in the temperature rise response evaluation value of the five grids under the wearing state. The horizontal axis is the grid number, and the vertical axis is the temperature rise response evaluation value of the corresponding grid. The gray dotted line marks the temperature rise response threshold, the red data points mark the potential high-risk area, and the blue data points mark the low response area. Among them, the temperature rise response evaluation values ​​of grids C2 and C3 are higher than the temperature rise response threshold and are marked as potential high-risk areas, displayed as red data points; the temperature rise response evaluation values ​​of the remaining grids are lower than the temperature rise response threshold and are marked as low response areas, displayed as blue data points. This figure intuitively reflects the difference in thermal drive response intensity of different grids under non-homogeneous wearing conditions, which helps to quickly identify local areas with prominent thermal sensitivity and further supports the setting of spread prediction paths and the construction of response step control strategies.

[0041] In this implementation, pre-processed flame-retardant fabric wear data is mapped to a two-dimensional simulation grid region and a physical input field is constructed for the simulation domain, achieving a structured binding of fabric moisture content, surface temperature, heat flux density, wrinkle angle, surface tensile strain, specific heat capacity, and latent heat of evaporation within each grid. By constructing a unit temperature rise benchmark term, a moisture-heat buffer ratio term, and a thermal shielding adjustment term, the system comprehensively characterizes the local influence of heat input intensity, fabric moisture content, and surface geometric perturbations, ultimately forming a partitioned calculation mechanism for temperature rise response assessment. This helps reveal the heterogeneous thermal response capabilities of fabrics under real-world wear conditions and provides fundamental indicators for subsequent asynchronous propagation trigger determination and response time step adjustment.

[0042] Specifically, the specific steps for executing combustion trigger judgment are as follows: The temperature rise response evaluation value of each grid is compared with the temperature rise response threshold in real time, and a partitioned asynchronous thermal response strategy is implemented based on the coupling of heat flux density, specific heat capacity, fabric moisture content, latent heat of evaporation, surface temperature, fold angle, and surface tensile strain: Grid cells with temperature rise response evaluation values ​​higher than the temperature rise response threshold are marked as potential high-risk areas. Such grids are usually accompanied by high heat flux density, low specific heat capacity, high fold angle, and significant stretching state, which are prone to thermal stress response. A smaller temperature rise response time step is assigned to them to improve the response resolution; Meshes with temperature-rise response assessment values ​​lower than the temperature-rise response threshold are marked as low-response areas. Such areas generally have high specific heat capacity, low moisture content, and limited temperature-rise capacity. A standard time step is assigned to them to maintain response stability. The response label and surface temperature of the grid are used as the joint triggering conditions for flame spread: potential high-risk areas are judged to be in a combustion state if the surface temperature exceeds the combustion judgment threshold at any time, reflecting their rapid response thermal instability characteristics. Low-response areas only enter a combustion state when the surface temperature continues to be higher than the combustion judgment threshold for three consecutive combustion judgment cycles, reflecting their hysteresis in temperature-rise response.

[0043] In this implementation, a partitioned asynchronous thermal response mechanism is constructed through real-time comparison of temperature-rise response assessments with temperature-rise response thresholds, combined with multi-source inputs consisting of heat flux density, specific heat capacity, fabric moisture content, latent heat of evaporation, surface temperature, wrinkle angle, and surface tensile strain. This mechanism distinguishes between potentially high-risk and low-response areas, assigning differentiated temperature-rise response time steps to each. Furthermore, the response label is combined with the surface temperature to trigger combustion state determination. This improves the flame spread model's ability to identify heterogeneous thermal response behaviors under wear conditions and enhances the accuracy of dynamic capture of early combustion initiation processes within the simulation domain.

[0044] Specifically, the specific steps of extracting the ignition time according to the combustion judgment results and quantifying the ignition deviation between the standard test and the wearing state are as follows: after completing the combustion judgment in the wearing state, based on the surface temperature change process recorded in the flame-retardant fabric wearing data, track the temperature evolution trajectory of each grid, and take the time step when the surface temperature first reaches the combustion judgment threshold as the grid's wearing state ignition time. This time node reflects the earliest combustion response of the fabric under the combined influence of fabric moisture content, heat flux density, fold angle, specific heat capacity and surface tensile strain; synchronously run the thermal diffusion process of the corresponding grid under the standard conditions of flatness, dryness and no strain of the fabric, and extract the standard ignition time without considering the influence of structural disturbance and moisture and heat, as a reference for the response time of the corresponding area in the standard test results; the wearing state The state ignition time is subtracted from the standard ignition time and multiplied by the temperature rise response evaluation value. This operation combines the response time difference and the local thermal sensitivity characteristics as the ignition response offset term, which is used to reflect the degree of disturbance of the ignition rhythm under actual wearing conditions; the fabric moisture content is divided by the fabric moisture content plus one, and then this ratio is subtracted from 1 as the moisture inhibition term, which is used to characterize the buffering effect of the local moisture state of the fabric on heat accumulation; the heat flux density, the heat shielding adjustment term and the moisture inhibition term are multiplied together to form a comprehensive heat input weakening term, which further quantifies the joint effect of the pleat angle, moisture heat buffering and heat input intensity; the ignition response offset term is divided by the comprehensive heat input weakening term to obtain the ignition offset evaluation value, which is used as the criterion variable for quantifying the degree of ignition timing offset, and is used to identify the timeliness mismatch risk of the standard test results under wearing conditions.

[0045] The specific calculation formula for the ignition offset evaluation value is:

[0046] ;

[0047] Where E represents the ignition offset evaluation value, Indicates the ignition time in wearing state, represents the standard ignition time, S represents the temperature rise response evaluation value, Q represents the heat flux density, Indicates the wrinkle angle, and W indicates the moisture content of the fabric.

[0048] In this implementation, the time steps at which the surface temperature reaches the combustion threshold are tracked to extract the worn ignition time and the standard ignition time. This is combined with the temperature rise response assessment to construct an ignition response offset term. This term incorporates fabric moisture content, heat flux density, specific heat capacity, surface temperature, pleat angle, and thermal shielding adjustments to form a comprehensive heat input attenuation term. Ultimately, an ignition offset assessment value is calculated. This assessment quantifies the difference in ignition time between standard testing and actual wear conditions, capturing the rhythmic changes in combustion response caused by both the moisture and heat conditions and structural disturbances. This provides a benchmark for subsequent evaluation of distortion identification and response correction mechanisms.

[0049] Specifically, the specific steps for correcting the temperature rise path of the test distorted grid and generating a data set of flame retardant performance response of clothing are as follows: compare the ignition offset evaluation value with the ignition offset threshold, and judge whether the ignition timing of the current area deviates from the standard test expectation based on the temperature rise response evaluation value, ignition response offset item and comprehensive heat input weakening item corresponding to each grid; if the ignition offset evaluation value is less than the ignition offset threshold, the grid test result is judged to be credible, marked as a credible area, and its original evaluation path is retained, and the response process of the grid based on heat flux density, specific heat capacity and fold angle is maintained; if the ignition offset evaluation value is greater than or equal to the ignition offset threshold, the grid test result is judged to be distorted, and the surface corresponding to the grid is extracted. The moisture content, wrinkle angle and surface tensile strain of the material are used as biasing factors to feed back to the correction path of the temperature rise response evaluation value. The temperature rise response evaluation value is recalculated on the basis of reconstructing the unit temperature rise benchmark item, the moisture heat buffer ratio item and the heat shielding adjustment item; then, combined with the corrected thermal driving capacity, the wearing state ignition time and ignition offset evaluation value of the grid are updated to reflect the regulatory effect of the actual structural state of the fabric on the combustion response; the evaluation data of the grid that has completed the correction calculation are unified and integrated, and the evaluation data include the temperature rise response evaluation value, the wearing state ignition time and the ignition offset evaluation value, to form a wearing flame retardant performance response data set covering all test result distorted grids, providing basic data support for the subsequent evaluation structure output.

[0050] In this implementation, the credibility of the test results is determined by comparing the ignition offset assessment value with the ignition offset threshold. A local response structure is constructed, consisting of the temperature rise response assessment value, the ignition time under wear, and the ignition offset assessment value. For grids with deviated ignition rhythms, the fabric moisture content, wrinkle angle, and surface tensile strain are extracted as biasing factors and fed back into the evaluation path. Key thermal input parameters are recalculated, and the thermal drive capacity is corrected. Finally, the calculation results of each grid are unified and integrated to generate a wear flame retardant performance response dataset. This dataset provides a dynamic compensation expression of flame retardant behavior under wear, enhancing the evaluation results' adaptability to fabric structural perturbations and thermal-moisture coupling.

[0051] Specifically, the specific steps for retrieving the flame retardant performance response data set and evaluating the distortion risk degree of the standard test in the wearing state are as follows: retrieve the flame retardant performance response data set, extract the normalized flame retardant fabric wearing data such as the temperature rise response evaluation value, fabric moisture content, latent heat of evaporation, heat flux density, specific heat capacity, surface temperature, surface tensile strain and wrinkle angle bound to each grid, construct a distortion risk discrimination structure, and analyze the distortion risk degree of the standard test in the wearing state; divide the temperature rise response evaluation value by the heat flux density, extract the response intensity based on the heat input, and normalize it to measure the unit heat flow. the warming potential of the fabric; the product of the moisture content and the latent heat of evaporation is divided by the product of the specific heat capacity and the surface temperature to construct a moisture-heat buffer term, which is used to quantify the thermal inhibition effect of the local moisture state of the fabric during the temperature rise process; the fold angle is converted into radians and its sine value is taken as the thermal shielding nonlinear interference term, which is used to characterize the first-order disturbance effect of the surface geometric disturbance on the directionality of the heat input; the moisture-heat buffer term, the surface tensile strain and the thermal shielding nonlinear interference term are added together to form the wearing evaluation interference term, which is used to aggregate the key interference components that affect the stability of the thermal response; the thermal response intensity is normalized and multiplied by the wearing evaluation interference term to obtain the standard test distortion evaluation value.

[0052] The specific calculation formula for the standard test distortion evaluation value is:

[0058] like Figure 4The figure shows a grid-level standard evaluation distortion determination diagram under different wearing conditions. It displays the standard test distortion assessment values ​​for five grid areas under different wearing conditions, and uses color to distinguish between the standard evaluation trustworthy areas and the evaluation distortion risk areas. The horizontal axis of the figure represents the grid number, and the vertical axis represents the standard test distortion assessment value for the corresponding grid. The gray dashed line represents the test distortion threshold. Grid G5's standard test distortion assessment value exceeds the test distortion threshold and is determined to be in the evaluation distortion risk area, shown as a red column. The remaining grids' assessment values ​​are below the test distortion threshold, marked as blue columns, and are determined to be in the standard evaluation trustworthy areas. This diagram helps identify the adaptability limitations of the standard evaluation method under different wearing conditions, thereby guiding subsequent compensation modeling and activation of response correction mechanisms.

[0059] In this implementation scheme, by calling the wearing flame retardant performance response data set, a standard test distortion evaluation value calculation path is constructed based on the temperature rise response evaluation value, heat flux density, fabric moisture content, latent heat of evaporation, specific heat capacity, surface temperature, surface tensile strain and wrinkle angle, forming a step-by-step derivation structure of thermal response intensity normalization term, moisture and heat buffer term, thermal shielding nonlinear interference term and wearing evaluation interference term, to achieve quantitative evaluation of the degree of standard test credibility deviation of each grid in the wearing state, provide direct indicator support for identifying the evaluation distortion area, and enhance the adaptive discrimination ability of the evaluation mechanism to multi-source disturbance input conditions.

[0060] Specifically, the specific steps of determining the dominant distortion source and performing response compensation, and outputting the credibility label and correction path covering the entire domain are as follows: Compare the standard test distortion evaluation value with the test distortion threshold, and establish an evaluation credibility classification strategy: If the standard test distortion evaluation value is less than the test distortion threshold, and the corresponding temperature rise response evaluation value is lower than the temperature rise response threshold, then the grid is determined to be a standard evaluation credibility area, and its original test path is retained; otherwise, the grid is determined to be an evaluation distortion risk area; for the grid in the evaluation distortion risk area, analyze the proportion of moisture and heat buffer items, shielding interference items, and tensile strain items in the wearing evaluation interference items to determine the dominant distortion source and select the corresponding compensation modeling path: If the moisture and heat buffer item is dominant, dynamically increase the temperature rise response time step according to the moisture content of the fabric, and delay the grid from entering the combustion judgment state to simulate the flame suppression effect in the wet area; if the shielding interference item is dominant, reconstruct the heat flux density of the grid. The effective heated area is corrected based on the wrinkle angle to replace the uniform input assumption under the standard state. If the tensile strain term is dominant, the temperature rise response step and the propagation path are dynamically reduced according to the surface tensile strain to simulate the influence of the structural tension change caused by the strain on the heat conduction rate and the flame advancement direction, and the high strain area is preferentially included in the temperature rise judgment window. The grid response results of the standard evaluation credible area and the evaluation distortion risk area are integrated to update the flame retardant performance response dataset of the clothing. Each grid is bound to the temperature rise response evaluation value, the ignition offset evaluation value, the standard test distortion evaluation value, the evaluation state label, the dominant component of the wearing evaluation interference item, the adjusted temperature rise response time step and the combustion judgment triggering mode. The flame retardant performance response dataset of the clothing is used to mark the blind area covered by the standard test and replace the original evaluation path of the distorted area to form a response judgment and path correction closed loop for the real wearing state.

[0061] In this implementation plan, a standard assessment credibility classification strategy is constructed by jointly comparing the standard test distortion assessment value with the test distortion threshold, combined with the response level of the temperature rise response assessment value, to determine the assessment status label of each grid. After identifying the assessment distortion risk area, the component proportions of the moisture buffer item, shielding interference item, and tensile strain item in the wearing assessment interference items are extracted to clarify the dominant distortion source. Response compensation modeling paths driven by fabric moisture content, wrinkle angle, and surface tensile strain are established, respectively, and differentiated corrections are made to the temperature rise response time step and flame spread judgment method. Finally, the various correction results are unified and integrated with the assessment credibility zone data to construct a wearing flame retardant performance response data set that binds the temperature rise response assessment value, ignition offset assessment value, standard test distortion assessment value, and compensation path parameters. This is used to replace the original test output of the distorted area, completing the closed-loop correction of the standard test path to the response structure under the actual wearing state.

[0063] In this implementation scheme, by constructing a performance control system consisting of a flame-retardant fabric wearing data acquisition and preprocessing module, a temperature rise response simulation and combustion judgment module, a response feature fusion and offset identification module, and an evaluation credibility reconstruction and response output module, a thermal response judgment path based on the measured wearing state data is established, and the structured input of fabric moisture content, surface temperature, heat flux density, wrinkle angle, surface tensile strain, specific heat capacity and latent heat of evaporation, dynamic extraction of temperature rise response evaluation value and ignition offset evaluation value, credibility identification of standard test distortion evaluation value and differentiated correction of response parameters are realized in turn, forming a closed-loop driven global response control mechanism, which provides multi-scale and multi-factor collaborative support for the accurate modeling of flame retardant performance for real wearing conditions.

[0064] The third aspect of the present invention provides a performance control device for flame-retardant fiber fabrics, comprising: a state perception integrator, a thermal drive response analyzer, an ignition offset quantizer, and an adaptability evaluation compensator, wherein: the state perception integrator is used to complete the collection, processing, and structural mapping of multi-source physical data under the wearing state of the fabric; the thermal drive response analyzer is used to analyze the temperature rise behavior under the action of heat input and identify potential high-risk areas for spread; the ignition offset quantizer is used to evaluate the response offset under standard and wearing conditions and perform path correction; the adaptability evaluation compensator is used to determine the evaluation distortion area and implement a response compensation strategy dominated by the wearing factor.
