ACRYLIC-FIBER FINISH FOR CARBON-FIBER PRODUCTION, ACRYLIC FIBER FOR CARBON-FIBER PRODUCTION, AND CARBON-FIBER PRODUCTION METHOD |
摘要 |
An acrylic-fiber finish for carbon fiber production is prepared into a stable emulsion and applied to a carbon-fiber precursor to prevent gumming up of finish components in precursor production and carbon fiber fusing in baking process. The acrylic-fiber finish is used for carbon-fiber production and includes a modified silicone having a modifying group containing a nitrogen atom and an acidic phosphate ester represented by the following chemical formula (1).;;where R1 represents a C6-22 alkyl or alkenyl group, A represents a C2-4 alkylene group, and AO represents an oxyalkylene group, n represents a mole number of oxyalkylene group and is an integer ranging from 0 to 20, and each of a and b is an integer of 1 or 2 and meets the equation a+b=3. |

1. An acrylic-fiber finish for carbon-fiber production, comprising essentially a modified silicone having a modifying group containing a nitrogen atom, and an acidic phosphate ester represented by the following chemical formula (1): where R1 represents a C6-22 alkyl or alkenyl group, A represents a C2-4 alkylene group, and AO represents an oxyalkylene group, n represents a mole number of oxyalkylene group and is an integer ranging from 0 to 20, and each of a and b is an integer of 1 or 2 and meets the equation a+b=3. |
