Based on test and analysis results of the structural parameters, the relevant performance indicators were measured in consideration of mechanical properties,comfort and style of fabrics, and the test data were systematically integrated and the relevant quantitative data were ultimately obtained.
As to the main factors of the structural parameters which greatly affect the performance of the fabrics, they will provide scientific evidence for the design and development of fabric.
Correlation Analysis of Structure and Properties on Fabric.
Comparison of mean value is the relationship between a parameter and a property, but a property affected by the overall structural parameters or a structural parameter affects the overall properties.
The performance changes are often caused by a variety of complex factors, thus the result of dispersion and volatility is relatively large; the partial correlation will be truly reflected unless the other factors are removed when partial correlation analysis is adopted.
