Embodiment Construction
[0046] The present invention will be further described below in combination with specific embodiments. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.
[0047] The invention is a method for measuring the theoretical porosity of fabrics by image method. The warp tightness and weft tightness of fabrics are determined by image processing method, the total tightness of fabrics is calculated according to the formula, and the theoretical porosity P is obtained by calculation. l =1-E; where,
[0048] E=E j +E w -0.01×E j ×E w ;
[0049] In the formula, E is the total tigh...
