Nanofibers, which have larger specific surface areas than conventional fibers, significantly enhance the functionality of conventional fiber materials in addition to introducing new features. Thermal barrier and sound insulation tests were conducted to assess the thermal and acoustic properties of the nanofilament fabrics prepared from polyethylene terephthalate (PET)/modified PET sea-island bicomponent fibers. The results indicate that fabrics with filament diameter of 400 nm exhibited excellent thermal and sound insulation performance compared to the fabrics with filament diameter of 600 nm.

This study examined the optical properties of nanofilament fabrics prepared from polyethylene terephthalate (PET)/modified-PET sea-island bicomponent fibers using an alkali treatment. The luster and anti-transparency properties of the fabrics before and after the alkali treatment were compared. The illuminance of the alkali-treated fabric relative to the position of an illuminometer was higher than that of untreated fabric, except for an illumination angle of approximately $270^{\circ}$, where much of the light was transmitted through the pores created by the removal of the sea materials. In addition, the alkali-treated fabric exhibited superior anti-transparency properties compared to the untreated fabric. Therefore, the outstanding optical performance of nanofilament fabrics was confirmed.

The most important characteristic of a nanofilament fabric is that it has a significantly higher surface area than conventional fabrics. Such nanofilament fabrics exhibit new physical properties that are unknown in conventional fibers, and it is anticipated that future demand of nanofilament fibers with improved fiber functionality could significantly increase. In this study, in order to analyze the size effect of the fiber, the optical properties of 800 nm and 600 nm filament fabrics were compared. The results showed that the 600 nm fabric had significantly more luster and less transparency as compared to the 800 nm fiber.
