FIBER HAVING PHASE SEPARATION STRUCTURE AND MANUFACTURING METHOD FOR SUCH FIBER

WIPO Patent Application WO/2015/146790

A1

The problem addressed by the present invention is to provide a fiber for which, despite having a phase separation structure, unevenness in fineness is small, dyeing unevenness and nap are suppressed, the durability of fiber characteristics with respect to long term storage and tumble drying are excellent, moisture absorption characteristics are excellent, anti-electricity characteristics in low temperature and low humidity environments are excellent, and elution of a hydrophilic compound when dyeing or using the fiber is suppressed. Provided is a fiber having a phase separation structure. The fiber is characterized by the following: comprising a copolymer of a hydrophobic polymer and a hydrophilic polymer; having a continuous phase and a dispersed phase according to a phase separation structure; the dispersed-phase maximum diameter in a fiber transverse cross-section being 1-40nm; and the fineness fluctuation value U%(hi) being 0.1-1.5%.
