no. 1 Embodiment approach

[0025] Hereinafter, 1st Embodiment of the polyolefin-type synthetic fiber processing agent (henceforth a processing agent) which actualized this invention is demonstrated. The processing agent of this embodiment contains the following polyoxyalkylene derivative and the following linear hydrocarbon.

[0026] The polyoxyalkylene derivative is one in which at least one selected from ethylene oxide and propylene oxide is added in a ratio of 5 to 100 moles with respect to 1 mole of aliphatic monohydric alcohol having 24 to 60 carbon atoms. compound.

[0027] The straight-chain hydrocarbon is a straight-chain hydrocarbon having 10 to 100 carbon atoms.

[0028] The polyoxyalkylene derivative used in the treatment agent of this embodiment is a polyoxyalkylene derivative selected from ethylene oxide and A compound of at least one kind of propylene oxide. The aliphatic monohydric alcohol having 24 to 60 carbon atoms is not particularly limited, and examples thereof include tetracosan...

no. 2 Embodiment approach

[0038]Next, a second embodiment of a polyolefin-based synthetic fiber (hereinafter referred to as a synthetic fiber) which is an embodiment of the present invention will be described. The synthetic fiber of this embodiment is a polyolefin type synthetic fiber to which the processing agent of 1st Embodiment adhered. Polyolefin-based synthetic fibers are not particularly limited, and examples thereof include polyolefin-based fibers such as polyethylene fibers, polypropylene fibers, and polybutene fibers. These may be used individually by 1 type, and may use it in combination of 2 or more types. In addition, it is a composite fiber having a core-sheath structure, and either or both of the core and the sheath are polyolefin-based fibers, such as polyethylene / polypropylene composite fibers in which the sheath is polyethylene fibers, polyethylene / polyester Composite fibers, etc.

[0039] The ratio of the treatment agent (excluding the solvent) of the first embodiment to the above-...

Abstract

A treatment agent for polyolefin-based synthetic fibers according to the present invention is characterized by comprising a polyoxyalkylene derivative as mentioned below and a linear hydrocarbon compound as mentioned below. The polyoxyalkylene derivative is a compound in which at least one oxide selected from ethylene oxide and propylene oxide is added at a ratio of 5 to 100 moles relative to 1 mole of a monovalent aliphatic alcohol having 24 to 60 carbon atoms. The linear hydrocarbon compound is a linear hydrocarbon compound having 10 to 100 carbon atoms. A polyolefin-based synthetic fiber according to the present invention is characterized by having, attached thereto, the treatment agent for polyolefin-based synthetic fibers.

Description

technical field [0001] The present invention relates to a treatment agent for polyolefin-based synthetic fibers and polyolefin-based synthetic fibers attached with the treatment agent. The treatment agent for polyolefin-based synthetic fibers endows polyolefin-based synthetic fibers with excellent The carded web made of olefin-based synthetic fibers has excellent initial hydrophilicity, durable hydrophilicity, and anti-wetting properties. Background technique [0002] In general, sanitary products such as disposable diapers are known in which polyolefin-based synthetic fibers are coated on the surface of a superabsorbent polymer in order to absorb body fluids. Synthetic fibers coated on the surface of superabsorbent polymers are particularly required: initial hydrophilicity to quickly absorb body fluids, durable hydrophilicity to repeatedly absorb body fluids quickly, and anti-leakage properties to prevent water retained in the superabsorbent polymers from leaking out. Hygr...
