用することは周囲の環境汚染の点で問題となる。The above-mentioned conventional dry pulp nonwoven fabric has a drawback that it is weak in strength and is easily broken during use. Further, a large amount of resin binder is required to impart paper strength, and there is a problem in safety when it is used as a non-woven fabric for wiping water / oil or for medical use. On the other hand, by laminating a long fiber web made of continuous hydrophobic long fibers and a paper sheet made of pulp fibers, by ejecting a high pressure water column flow from the paper sheet side to the long fiber web side, A method for producing a nonwoven fabric by intertwining fibers has been proposed. According to this manufacturing method, since the resin binder is not used, it is suitable for use in the medical field, etc. However, it is necessary to collect and incinerate it because it does not biodegrade when discarded. Furthermore, the use of this nonwoven fabric as an agricultural material poses a problem in terms of environmental pollution in the surroundings.

It is an object of the present invention to provide a hydroentangled non-woven fabric that can be used as an agricultural material, and a method for producing the same.

を作成した。Example 5 NBKP (softwood bleached kraft pulp) (40%) and bagasse (60%) were dispersed in water, and paper was made with a suction former paper machine (not shown) to obtain a sheet (wet paper). Then, the first sheet was placed on a conveyor formed of wire mesh, and while the sheet was conveyed at a line speed of 15 m / min, nozzle holes having a hole diameter of 0.12 mm were linearly arranged at 0.60 mm intervals. A high-pressure water column flow was jetted to one side of the sheet at a water pressure of 50, 50, and 60 kg / cm 2 in order using a jetting device in the high-pressure water column flow treatment step. In this case, the sheet is further inverted, and 90, 90, 100 kg / c are sequentially used by using the ejection device of the second high-pressure water column flow treatment step.
A high pressure water column flow was jetted to the opposite surface of the sheet with a water pressure of m 2 . That is, a high-pressure water column flow was ejected on both sides of the sheet, and then the sheet was guided to a through dryer and dried to prepare a hydroentangled nonwoven fabric.
【００１６】このようにして形成した水流絡合不織布の

It has 3 times the strength and can be judged to be durable enough to use. Further, the raw material of the non-woven fabric does not need to be 100% of wood pulp, it is possible to mix 60% of bagasse, and the high-pressure water column jetting treatment gives a sufficiently good result even with only one side of the sheet as in Example 4.

であった。Regarding the performance, the water absorption rate of Examples 1 and 2 is remarkably high, and the water absorption capacity is inferior to that of Comparative Example 1, but is superior to that of Comparative Example 2. The same applies to the oil absorption capacity. Further, as can be seen from the example of Example 3 (secondary processing by a thermal calender), when the surface of the hydroentangled nonwoven fabric is secondarily processed, both the water absorption function and the oil absorption function decrease, but the texture becomes closer to that of the cloth. . The wiping properties of Examples 1 to 5 were superior to those of Comparative Examples 1 and 2, and particularly, Examples 1 and 2 were extremely good.

布を作成した。[Example 5] 40% of NBKP (softwood bleached kraft pulp) and 60% of Manila hemp were dispersed in water, and paper was made with a suction former paper machine (not shown) to obtain a sheet (wet paper). Then, the sheet was placed on a conveyor formed of wire mesh, and while this sheet was conveyed at a line speed of 15 m / min, a nozzle hole having a hole diameter of 0.12 mm was 0.60 mm.
50, 50, 60 kg / cm 2 in order using the jetting device of the first high-pressure water column flow treatment step arranged in a straight line at intervals.
A high-pressure water column flow was jetted to one side of the sheet with the water pressure of. In this case, the sheet is further turned over, and 90, 90, 100 kg are sequentially used by using the ejection device of the second high-pressure water column flow treatment step.
A high-pressure water column flow was jetted to the opposite surface of the sheet with a water pressure of / cm 2 . In other words, eject a high-pressure water column flow on both sides of the sheet,
Then, it was guided to a through dryer and dried to prepare a hydroentangled nonwoven fabric.

【００１９】実施例４及び実施例５は、ＤＲＹでの引張
強度が比較例２よりも強く、ＷＥＴでの引張強さは比較
例２よりは遥かに劣るが、比較例１に比して２〜３倍の
強度を有しており、充分使用に耐えるものと判断でき
る。更に、不織布の原料は木材パルプ１００％でなくと
も良く、マニラ麻を６０％混入することが可能であり、
又高圧水柱流噴出処理は実施例４のようにシートの片面
のみでも充分良い成績があげられることが判明した。In Examples 4 and 5, the tensile strength in DRY is stronger than that in Comparative Example 2 and the tensile strength in WET is far inferior to Comparative Example 2, but it is 2 as compared with Comparative Example 1. It has 3 times the strength and can be judged to be durable enough to use. Further, the raw material of the non-woven fabric does not have to be 100% wood pulp, and it is possible to mix 60% Manila hemp ,
It was also found that the high pressure water column flow jetting treatment can achieve sufficiently good results even with only one side of the sheet as in Example 4.
