Abstract

The present invention relates to a system for measuring fibre tropism distribution of nonwoven fabric and method thereof. The system comprises microscope, lamp-house, CCD vidicon, interface accessory,image acquisition card and computer, the said lamp-house is set under the stage of microscope, CCD vidicon is set on the top of microscope through interface accessory and magnifies image of nonwovenfabric, the said image acquisition card changes the image of nonwoven fabric into digital imagine and input the digital image to computer. The measuring method comprises: sampling nonwowen fabric firstly, collecting image of nonwoven fabric, processing image of nonwoven fabric and measuring fiber tropism distribution of nonwoven fabric. The present invention resolves problem of measuring efficiently fiber tropism distribution of nonwowen fabric, realizes sampling nonwoven fabric scientifically and reasonably, and the present invention has the advantages of easy operation, low cost of equipmentand credibility measurement result.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a method for measuring the orientation distribution of nonwoven fabric fibers. Background technique [0002] With its unique processing methods and structural properties, nonwovens are playing an important role in all aspects of production and life. In medical and health, civil engineering, environmental protection, agriculture and other fields. Since the nonwoven fabric is a fiber aggregate directly composed of fiber materials, the properties of the fiber material have a direct impact on the performance of the nonwoven fabric. The orientation distribution of fibers is closely related to the physical and mechanical properties of nonwovens, especially the mechanical anisotropy of nonwovens is directly related to the orientation distribution of fibers. Therefore, measuring and controlling the orientation distribution of fibers is very important for the product design and quality...
