Various fiber types consisting of a single nonwoven fabric were investigated to provide a combination of good strength and filtration characteristics. Polyester staple fiber (PSF) 3, 6, and 15 denier, low melting PSF (LM-PSF) 4 denier, 3-ball-type, non-circular shaped, PSF 2 denier (NC-PSF), and splittable micro-PSF 2 denier (SM-PSF) that were divided into 8 pieces by needle punching force were used for investigation. The effects of the enormous increase in the surface area and the reduction in pore size due to the use of finer fibers are reported. As the fiber denier size was reduced, the dust arresting efficiency increased and the air permeability decreased. The dust arresting efficiency also increased with increasing SM-PSF content.

It is important for automobile manufacturers to eliminate unwanted noise in passenger compartments of vehicles. One of the methods free from noise is to use sound absorbing materials such as floor coverings, package trays, door panels and luggage compartments in auto interiors. In this study, the needle punched nonwovens were produced with the various blending ration of Non-circular shaped polyester, 2 denier and splittable micro-fiber, 2 denier. The sound absorption characteristic of nonwovens and corresponding mechanical properties are explored.
압축공기를 이용한 3차원 부직포 구성섬유의 배향구조 형성에 관한 연구

3-dimensional nonwoven fabrics show high loft performance owing to their dominant fiber orientation in the thickness direction. A high loft performance is a fundamental requirement for applications to cushion materials and pre-filters etc. In this study, the process was optimized to obtain 3-dimensional nonwoven fabrics with improved physical properties. The process conditions, such as the distance between the air ejection nozzles, compressed air pressure and web sustaining mesh size, were examined to develop a fiber orientation in the thickness direction of nonwoven fabrics. The mechanical properties and fiber orientation distribution function (ODF) were compared.
