[0034] In a preferred embodiment, this specification also provides a method for evaluating the extensibility of knitted fabrics in a complex environment, and the evaluation method includes the steps of:
[0035] S201. Determine multiple influencing factors related to the extensibility of the knitted fabric.
[0036] According to the use process of knitted fabrics, it can be known that in complex environments, there are many factors that affect the extensibility of knitted fabrics, including: internal and external factors, of which external factors include ambient temperature, ambient humidity, washing type, washing intensity, washing Time and loss, etc., internal factors include fabric type, fabric temperature and fabric humidity, etc.
[0037] Therefore, before determining the influencing factors related to extensibility, it is necessary to conduct a correlation analysis between each influencing factor and extensibility to determine the main influencing factors related to extensibility. In the embodiment of this specification, the correlation analysis between each influencing factor and the extensibility of knitted fabrics is carried out, and the correlation coefficient threshold is set to determine that the main influencing factors related to extensibility include fabric type, ambient temperature, ambient humidity, and fabric temperature. , fabric humidity and loss.
[0038] S202. Establish a multivariate evaluation model that uses evaluation values of various influencing factors as input variables and evaluation values of extensibility as output variables.
[0039] Quantitative assignment is carried out for each influencing factor respectively, and the multivariate evaluation model is: Y=a 1 x 1 +a 2 x 2 +…+a n x n+δ, where Y represents the evaluation value of extensibility; a 1 、a 2 and a n Respectively represent the weight coefficients of each influencing factor; x 1 、x 2 and x n Respectively represent the evaluation values of different influencing factors; n represents the number of influencing factors, preferably 6; δ represents the correction coefficient, and the elongation evaluation value adopts the maximum extension ratio of the knitted fabric; parameter value.
[0040] S203, making statistics on the historical data, respectively substituting them into the multivariate evaluation model for solution, and obtaining the weight coefficients of each influencing factor. Preprocessing the statistical historical data includes removing large error values and performing interpolation processing on historical data by setting thresholds.
[0041] The extensibility evaluation value of different knitted fabric history and the corresponding evaluation value of each influencing factor were counted separately, and substituted into the multivariate evaluation model to form a statistical equation group of historical data, and the weight coefficient of each influencing factor was solved by using the least square method. At the same time, the value of the correction coefficient δ is obtained.
[0042] The statistical equations of the historical data are: Among them, Y 1 Indicates the extended evaluation value of the first set of histories; Y m Indicates the extensibility evaluation value of the m-th group history; x 11 、x 12 and x 1n Respectively represent the evaluation values of the first group of different influencing factors; x m1 、x m2 and x mn Respectively represent the evaluation values of different influencing factors of the mth group; m represents the number of groups of historical data, preferably 10 groups.
[0043] S204. Measure the evaluation values of various influencing factors related to the extensibility of the knitted fabric to be evaluated.
[0044] After the knitted fabric to be evaluated is selected, the relevant influencing factors of the knitted fabric to be evaluated are measured separately, including the temperature and humidity of the environment where the knitted fabric to be evaluated is currently located, and the temperature and humidity of the knitted fabric to be evaluated are measured separately, and the temperature is measured in Celsius The relative humidity is used for temperature and humidity, and the loss of the fabric to be evaluated is measured to obtain the evaluation value of various influencing factors; the fabric type uses different values to distinguish different types of fabrics, and assigns values to the fabric types. Among them, the loss is calculated by the mass loss method, and the control variable method is used to measure the quality of the knitted fabric to be evaluated and the quality of the brand-new knitted fabric under the same conditions of other influencing factors. The difference is the amount of loss.
[0045] S205. Substituting the evaluation values of various influencing factors related to the extensibility of the knitted fabric to be evaluated into a multivariate evaluation model to obtain an evaluation value of the extensibility of the knitted cloth to be evaluated.
[0046] This manual provides an evaluation method for the extensibility of knitted fabrics in a complex environment. Through statistical historical data, a multivariate evaluation model between various influencing factors and the extensibility of knitted fabrics is established, so as to evaluate the knitting fabrics affected by various influencing factors. The fabric extensibility is evaluated, the evaluation method is simple, and the reliability of the evaluation results is high. At the same time, the evaluation results are used to help the subsequent improvement and improvement of the knitted fabric extensibility.
[0047] Using the evaluation method for the extensibility of knitted fabrics in complex environments provided by one or more embodiments of this specification to evaluate the extensibility of knitted fabrics in complex environments, first determine the influencing factors related to the extensibility of knitted fabrics, because the influencing factors There are many, so it is necessary to select the influencing factors that are more relevant to the extensibility of knitted fabrics. Correlation analysis is usually used to analyze various influencing factors. The specific analysis process is as follows: Using the control variable method, the influence of different influencing factors on the extensibility of knitted fabrics is respectively measured, the extension length of knitted fabrics is used as the dependent variable, and the change of influencing factors is used as the independent variable. , the correlation coefficient r between each independent variable and the dependent variable, the correlation coefficient r is calculated by the product-difference method, and the closer the absolute value is to 1, the stronger the correlation between the two is. Set the correlation coefficient threshold to 0.9, compare the absolute values of multiple correlation coefficients r obtained in turn with the correlation coefficient threshold, and select the influencing factors with the absolute value of r greater than 0.9 as the main influencing factors related to the extensibility of knitted fabrics; Quantify the value of each influencing factor, that is, the evaluation value of the influencing factors, and establish a multivariate evaluation model between the evaluation values of these influencing factors and the evaluation value of the extensibility of knitted fabrics, because each influencing factor has a different degree of influence on the extensibility of knitted fabrics , so the weight coefficient is used to evaluate the influence degree of each influencing factor; the statistical historical knitted fabric extensibility evaluation value and the corresponding influencing factor evaluation value are substituted into the multivariate evaluation model to obtain the weight coefficient of each influencing factor evaluation value and the correction coefficient, and then substituting the evaluation value of each influencing factor of the knitted fabric to be evaluated into the multivariate evaluation model can obtain the extensibility evaluation value of the knitted fabric to be evaluated.
