| titleOfInvention | Porous hollow fiber |
| abstract | PROBLEM TO BE SOLVED: To provide a porous hollow fiber that is light in weight and high in heat retention, with a uniform diameter of the hollow part even if the proportion of the hollow part is large. SOLUTION: A porous hollow fiber obtained by removing an island component from a plurality of sea-island type composite fibers having an easily soluble polymer as an island component and a hardly soluble polymer as a sea component, The number of hollow parts observed in the fiber cross section perpendicular to the vertical direction is 100 or more per porous hollow fiber, the interval between adjacent hollow parts is 100 nm or more, and the diameter of each hollow part Is in the range of 10 to 1000 nm, the variation in the diameter of the hollow part (CV value) is 30% or less, and the hardly soluble polymer converts the specific metal salt compound to 100 mol% of the dicarboxylic acid component of the hardly soluble polymer. A porous hollow fiber which is contained at a ratio of 0.5 to 2.0 mol% with respect to the carbon and further contains a specific phosphorus compound. [Selection] Figure 3 |
