Abstract

Official abstract text for this publication.

A synthetic fiber treatment agent and synthetic fibers including the synthetic fiber treatment agent, wherein the synthetic fiber treatment agent contains a silicone and a polyoxyalkylene alkyl ether in which an alkylene oxide with 2 to 4 carbon atoms is added at a ratio of 1 to 30 moles in total to 1 mole of a monohydric aliphatic alcohol having a hydroxy group at a β-position of an alkyl chain with 4 or more carbon atoms.

First claim

Opening claim text (preview).

The invention claimed is: 1. A synthetic fiber treatment agent comprising: a polyoxyalkylene alkyl ether in which an alkylene oxide with 2 to 4 carbon atoms is added at a ratio of 12 to 30 moles in total to 1 mole of a monohydric aliphatic alcohol having a hydroxy group at a β-position of an alkyl chain with 4 or more carbon atoms; and a silicone selected from the group consisting of dimethyl silicone and polyether-modified silicone. 2. The synthetic fiber treatment agent according to claim 1 , wherein the alkylene oxide contains ethylene oxide. 3. The synthetic fiber treatment agent according to claim 1 , wherein the monohydric aliphatic alcohol has the hydroxy group at a β-position of an alkyl chain with 10 to 18 carbon atoms. 4. The synthetic fiber treatment agent according to claim 1 , wherein the monohydric aliphatic alcohol has the hydroxy group at a β-position of an alkyl chain with 12 to 16 carbon atoms. 5. The synthetic fiber treatment agent according to claim 1 , wherein a content of the polyoxyalkylene alkyl ether is 5 to 80 parts by mass and a content of the silicone is 95 to 20 parts by mass, wherein the sum of the contents of the polyoxyalkylene alkyl ether and the silicone is taken as 100 parts by mass. 6. The synthetic fiber treatment agent according to claim 1 , wherein the synthetic fiber is a carbon fiber precursor. 7. A synthetic fiber to which the synthetic fiber treatment agent according to claim 1 is adhered.
