摘要： The present invention addresses the problem of improving friction characteristics, when wet, of fibers to which a treatment agent for short fibers is adhered, and improving the heat resistance of the treatment agent for short fibers. This treatment agent for short fibers does not substantially include a phosphate compound, but does contain the fatty acid (A) below and a non-ionic surfactant. The fatty acid (A) is at least one fatty acid selected from C1-6 fatty acids, C1-6 hydroxy fatty acids, and salts of the aforementioned fatty acids.

摘要： A process for producing an alkylene oxide adduct can continuously produce the alkylene oxide adduct by using a microflow reactor having a tubular flow passage and a micromixer connected to a supply port of the microflow reactor. Liquid state alkylene oxide, alkylene catalyst and an organic compound having an active hydrogen atom(s) are reacted while passing therethrough under the conditions of a temperature of the flow passage of 70 to 200° C. and a pressure of the supply port of the flow passage of 1 to 10 MPa.
