Abstract

A sheet manufacturing method includes a step of mixing fibers and a composite integrally including a resin and a coagulation inhibitor and a step of bonding the fibers and the composite. The composite is a powder whose volume average particle diameter is 1 μm or more to 100 μm or less, and at least a portion of the coagulation inhibitor is arranged in a surface of the composite.

Claims

exact text as granted — not AI-modified
1 . A sheet manufacturing method comprising:
 a step of mixing fibers and a composite integrally including a resin and a coagulation inhibitor, the composite being a powder whose volume average particle diameter is 1 μm or more to 100 μm or less, at least a portion of the coagulation inhibitor being arranged in a surface of the composite; and   a step of bonding the fibers and the composite.   
     
     
         2 . The sheet manufacturing method according to  claim 1 ,
 wherein the composite is a powder whose volume average particle diameter is 5 μm or more to 35 μm or less.   
     
     
         3 . The sheet manufacturing method according to  claim 1 ,
 wherein a number average particle diameter of the coagulation inhibitor is 0.001 μm or more to 1 μm or less.   
     
     
         4 . The sheet manufacturing method according to  claim 1 ,
 wherein a coverage ratio of the surface of the composite by the coagulation inhibitor is 20% or more to 100% or less.   
     
     
         5 . The sheet manufacturing method according to  claim 1 ,
 wherein the coagulation inhibitor is 0.1 parts by weight or more to 5 parts by weight or less with respect to 100 parts by weight of the composite.
