FILLER-FIXED FIBER, FIBER STRUCTURE, MOLDED FIBER, AND PROCESSES FOR PRODUCING THESE

摘要

A filler-fixed fiber which comprises a fiber (2), a binder resin (1) disposed on the surface thereof, and a filler (3) fixed to the binder resin (1), wherein the binder resin (1) is a moisture/heat-gelling resin which gels upon heating in the presence of water and the filler (3) has been fixed to the gel obtained by causing the moisture/heat-gelling resin to gel. Due to this, the fiber (2) retains its fiber form and the gel formed by the gelation of the moisture/heat-gelling resin functions as a binder for fixing the filler (3).
