    Abstract: Methods to produce structures containing ultrafine fibers with average diameters from 10 nm to 10 ?m and more preferably from 50 nm to 5 ?m, have been developed. These methods produce ultrafine fibers without substantial loss of the polymer's weight average molecular weight. The ultrafine electrospun fibers have an unexpectedly higher degree of molecular orientation, and higher melt temperature than fibers derived by dry spinning. In the preferred embodiment, the polymer comprises 4-hydroxybutyrate. The ultrafine fibers are preferably derived by electrospinning. A solution of the polymer is dissolved in a solvent, pumped through a spinneret, subjected to an electric field, and ultrafine fibers with a high degree of molecular orientation are collected.

  • Patent number: 9523192
    Abstract: Disclosed are a sound-absorbing material with improved sound-absorbing performance and a method for manufacturing the sound-absorbing material. The sound-absorbing material may improve sound absorption coefficient and transmission loss by forming large surface area and air layer, so as to induce viscosity loss of incident sound energy, and may provide light-weight design of a sound absorbing part or material since sound-absorbing performance may be substantially improved using reduced amount of fiber. Further, the sound-absorbing material may improve sound-absorbing performance by using binder fiber having rebound resilience, so as to maintain enough strength between fibers and also to maximize viscosity loss of sound energy transmitted to fiber structure.
