    摘要: The present invention provides a plastic optical fiber comprising a core and a sheath consisting of at least one layer, the plastic optical fiber having a transmission loss of 120 dB/km or less as measured by a 25m-1m cutback method under conditions of a wavelength of 525nm and an excitation of NA=0.45, and satisfying either one of the following conditions when a thickness of the innermost sheath layer is 0.5µm to 4.5µm, an amount of foreign matter having a size of 2 µm or greater contained in the innermost sheath layer is 2000/cm 3 or less, or a size X (µm) of foreign matter contained in the innermost sheath layer and an amount Y of the foreign matter (number/cm 3 ) satisfy formula (1) below: Y ≤ 1200 X e (-0.067xX) (1). Such optical fibers have a low transmission loss of green light (in particular, light having a wavelength of 525nm), enabling longer distance communication.

    摘要: The PTFE real twist yarn of the present invention is a PTFE real twist yarn (41) obtained by twisting a polytetrafluoroethylene (PTFE) multi-filament slit yarn. The yarn has a circular cross-section with a circularity in the range of 10/8 to 10/10, where the circularity is expressed by the ratio between the major axis width and the minor axis width, the average fineness of filaments (42) is in the range of 1.5 to 200 dtex, a fineness D is in the range of 50 to 6000 dtex, and a twist coefficient K expressed by Formula (1) is in the range of 10000 to 35000: t ⁢ w ⁢ i ⁢ s ⁢ t c ⁢ o ⁢ e ⁢ f ⁢ f ⁢ i ⁢ c ⁢ i ⁢ e ⁢ n ⁢ t K = n ⁢ u ⁢ m ⁢ b ⁢ e ⁢ r o ⁢ f t ⁢ w ⁢ i ⁢ s ⁢ t ⁢ s T × t ⁢ h ⁢ e f ⁢ i ⁢ n ⁢ e ⁢ n ⁢ e ⁢ s ⁢ s D o ⁢ f t ⁢ h ⁢ e P ⁢ T ⁢ F ⁢ E r ⁢ e ⁢ a ⁢ l t ⁢ w ⁢ i ⁢ s ⁢ t y ⁢ a ⁢ r ⁢ n 1 / 2
