Abstract:
1. An acrylic-fiber finish for use in carbon-fiber production, the finish essentially comprising an epoxy-polyether-modified silicone; an amino-modified silicone; and a surfactant, wherein the weight ratio of the epoxy-polyether-modified silicone ranges from 1 to 95 wt % and the weight ratio of the surfactant ranges from 5 to 50 wt % in the total of the nonvolatile components of the finish, wherein the total weight ratio of the epoxy-polyether-modified silicone and the amino-modified silicone ranges from 50 to 95 wt % in the total of the non-volatile components of the finish, and the weight ratio between the epoxy-polyether-modified silicone and the amino-modified silicone ranges from 5:95 to 90:10; the epoxy-polyether-modified silicone is at least one compound selected from the group consisting of a compound represented by the chemical formula (1) shown below and a compound represented by the chemical formula (2) shown below, where each of the symbols in formulae (1) and (2) independently represents the meaning as follows: Ep: an epoxy group represented by the chemical formula (3) or (4) shown below A: a C Ra: a C Rb: a C Rc: a hydrogen atom or a C r: an integer ranging from 1 to 50 p: an integer ranging from 1 to 10,000 q: an integer ranging from 1 to 100 s: an integer ranging from 1 to 100 t: an integer ranging from 1 to 100 B, D: a C F, G: a C
