Effect of Fiber Arrangement on the Mechanical Properties of Thermally Bonded Nonwoven Fabrics

Anisotropy is important to the structure and application of nonwoven fabrics. The arrange ment of the fibers and their orientation distribution are related to the mechanical structure of the web. In this study, we used a doffer of the roller card accompanied by a random roller to produce nonwoven fabrics. Partial random fiber arrangement is obtained by transferring the fibers on the rollers. As a result, the ratios of tensile and tearing strengths of the random web are below 3.0 and above 0.5, respectively. We can use this novel random arrangement of fibers in webs to improve the anisotropy of nonwoven fabrics.
