Description
Technical Field
The present invention relates to a treatment agent for a nonwoven fabric made of polyolefin synthetic fibers, and a spunbond nonwoven fabric made of polyolefin synthetic fibers.
Background
Generally, polyolefin synthetic fibers are used as raw material fibers of nonwoven fabrics. For example, nonwoven fabrics are produced by a spunbonding method using polyolefin-based synthetic fibers. The nonwoven fabric produced by the spunbond process is referred to as a spunbond nonwoven fabric. The functions such as durable hydrophilicity of the nonwoven fabric are imparted by applying an oil agent as a treating agent for the nonwoven fabric to the nonwoven fabric. Nonwoven fabrics to which functions such as durable hydrophilicity are imparted are used in a wide range of fields such as sanitary materials, medical fields, and civil engineering fields.
Patent document 1 discloses a water permeability imparting agent as a treating agent for nonwoven fabrics, which contains an alkylene oxide adduct of a polyvalent active hydrogen compound. As a polyvalent active hydrogen compound, patent document 1 discloses a partial ester formed from a polyhydric alcohol having a valence of 3 to 6 and a fatty acid.

(Durable hydrophilic)
The spun-bonded nonwoven fabric produced in test class 2 was cut into 10cm×10cm pieces. The sheeted nonwoven fabric was humidified in a constant temperature chamber having a relative humidity of 60% at 20℃for 24 hours.
The humidified nonwoven fabric was placed on 5 sheets of filter paper. Next, a cylinder having an inner diameter of 1cm and open at both ends was placed on the center portion of the nonwoven fabric so that the axial direction was a vertical direction.
10Ml of 0.9% physiological saline was poured into the cylinder. The state of absorption of the physiological saline by the nonwoven fabric was visually observed, and the time until the physiological saline was completely absorbed was measured.
Then, the nonwoven fabric was taken out, and the nonwoven fabric was blown with warm air at 40 ℃ for 90 minutes to dry the nonwoven fabric by air blowing. After the air-blown drying, the test of humidifying the nonwoven fabric and absorbing physiological saline was repeated 3 times again. The results of the 3 rd pass were evaluated using the following evaluation criteria. The results are shown in the column "durable hydrophilicity" of Table 6.
Evaluation criterion of durable hydrophilicity
Very good: the time required for the physiological saline to be completely absorbed is less than 5 seconds
(Yet): the time required for the physiological saline to be completely absorbed is more than 5 seconds and less than 7 seconds
X (bad): the time required for the physiological saline to be completely absorbed is more than 7 seconds
From the results of table 6, it is clear that the wettability of the treatment agent for nonwoven fabric made of polyolefin synthetic fibers with respect to the polyolefin synthetic fibers can be improved preferably according to the present invention. In addition, the durable hydrophilicity of the polyolefin synthetic fiber spunbond nonwoven fabric to which the treatment agent for the polyolefin synthetic fiber nonwoven fabric is attached can be improved.
