This sheet consists of fibers with extremely fine and complex cross sections.

でも均一な（８油性付与を可能とした。Corona discharge treatment is performed on flat surfaces such as films in order to impart adhesiveness and wettability. However, it is surprising that the oil repellent could be applied uniformly even to a microfibrillated and structurally inhomogeneous surface such as the nonwoven sheet of the present invention by applying corona discharge treatment. It is. Although this is thought to be microscopically nonuniform, by setting the macroscopic wetting tension, which is a macroscopic index, to 42 dyn/cm or more, even the oil repellent on the receiving surface can be uniformly applied (8 oiliness).

This is the value of surface tension extrapolated to =1.
本発明の不感シートの空隙率は７５％以下が好ましい。The porosity of the insensitive sheet of the present invention is preferably 75% or less.
空隙率が７５％をこえると毛羽立ちやすく、また強度的

あることが好ましい。The 1B oil agent is dispersed in an aqueous solution to form an emulsion, or dissolved in a solvent and applied to a nonwoven polyolefin sheet. For example, in the case of a fluorocarbon-based oil repellent, the appropriate amount of oil repellent to be applied is 0.1 to 2.0 g/rd to the nonwoven polyolefin sheet, but if it is less than 0.1 g/rrf, the oil dissolving effect will be poor. is not enough,
If it exceeds 2.0 g/rrT, an oil repellent film will form on the surface of the insensitive polyolefin sheet, impairing air permeability, which is not preferable. In order to impart oil repellency without impairing air permeability, the amount of oil repellent applied is preferably 0.1 to 1.0 g/rd.

A method of dipping a non-woven polyolefin sheet in an oil repellent solution, ■ A method of applying an IB oil solution to a non-woven polyolefin sheet using a kiss roll or gravure roll, ■
There are methods such as applying an oil repellent solution to a non-woven polyolefin sheet by spraying, but in the case of the spray method, the oil repellent adheres to the surface of the non-woven sheet in the form of droplets.
After the spray treatment, it is necessary to rub the surface of the sheet to which the oil repellent is applied with a pred-shaped object, a rod-like object, a rotating roll, etc. to form a uniform film of the oil repellent on the surface of the sheet. Furthermore, if alcohols, surfactants, etc. are added to the oil repellent solution, the oil repellent will adhere evenly in a layer.
