るとシール面が硬くなり、透明化するので、商品価値が
損なわれる。(Prior Art) A nonwoven sheet made of polyolefin alone has a problem in heat sealability. That is, when heat-sealing, the sealing surface becomes hard and transparent, which impairs its commercial value.

くないことなど必ずしも満足できるものではない。Therefore, there is a method of laminating a perforated polyethylene film as a method of maintaining breathability and imparting heat sealability to a nonwoven sheet, but the perforated polyethylene film is expensive and the pore size is large, making it difficult to breathe. The fact that the adjustment is not wide is not necessarily satisfactory.

ものとは表面のミクロ構造が異なるものである。The specific surface area of the nonwoven sheet in the present invention is 1 to 15rrf
/g. This nonwoven sheet has a large specific surface area, and its surface microstructure is different from that of a normal nonwoven sheet or a sheet that is uniform over the entire surface such as a film.
比表面積が１ ｒｄ ／ ｇより小さい場合は不織シー
トに大孔径の穴が存在するため、ポリオレフィン系粒子
を塗布することによる通気性の調整は困難となる。When the specific surface area is less than 1 rd/g, large pores exist in the nonwoven sheet, making it difficult to adjust air permeability by applying polyolefin particles.

本発明におけるポリオレフィン系粒子よりなるラテック
スとは、ポリエチレン、ポリプロピレン、あるいはポリ
オレフィン系あるいは共重合可能な不飽和モノマーとの
共重合体を原料しするものがあげられる。The latex made of polyolefin particles in the present invention includes those made from polyethylene, polypropylene, polyolefin, or a copolymer with a copolymerizable unsaturated monomer.

径が２μｌより小さいと通気性が小さくなり、通気性を
調整することがむずかしい。In the present invention, the particle size of the polyolefin particles in the latex is preferably 2 to 15 μl. When the particle size is smaller than 2 μl, air permeability decreases and it is difficult to adjust air permeability.
又、１５μ晴を越えると逆に通気性が大きすぎて、通気
性を調整することがむずかしい。On the other hand, if the thickness exceeds 15 μm, the air permeability is too high and it is difficult to adjust the air permeability.
ポリオレフィン系粒子のＭＦＴは７０°Ｃ以上が通気性

ることもできる。The MFT of the polyolefin particles is preferably 70°C or higher in order to adjust air permeability. M of polyolefin particles
The upper limit of FT varies depending on the raw material of the nonwoven sheet used, but when the nonwoven sheet is polyethylene, it is 125°C or less, preferably 120°C or less. When the nonwoven sheet is polypropylene, the temperature is 150°C or less, preferably 140°C.
It is as follows. Further, polyolefin particles having different MFTs and polyolefin particles having different diameters may be mixed and used.
本発明における不織シートへのポリオレフィン系粒子か
らなるラテックスの塗布方法としては、キスロール法、
グラビアロール法、スクイズロール法、ナイフコーター
法等があげられる。In the present invention, methods for applying latex made of polyolefin particles to the nonwoven sheet include kiss roll method,
Examples include gravure roll method, squeeze roll method, knife coater method, etc.
塗布量は４〜３０ｇ／ｒｒｌが好゛ましい、４μｌポよ
り少ない場合は、通気性を調整することが難しい。又、
３０ｇ／ｒｒｆ以上では通気性もほとんど無くなってし
まい、通気性を調整したものを得るのは難しい。The coating amount is preferably 4 to 30 g/rrl; if it is less than 4 μl, it is difficult to adjust the air permeability. or,
If it exceeds 30 g/rrf, the breathability will almost disappear, making it difficult to obtain a material with adjusted breathability.
ラテックスを不織シートに塗布するに際しては、不織シ

、ラテックスの表面張力を調整することも、同様に均一
塗布に有効である。When applying latex to a nonwoven sheet, corona treatment of the surface of the nonwoven sheet to improve surface tension is effective for uniform application of the latex. Alternatively, adjusting the surface tension of the latex by adding an appropriate amount of alcohol such as isopropyl alcohol or butyl alcohol to the latex made of polyolefin particles is similarly effective for uniform application.
本発明における熱処理方法としては、熱風加熱法、加熱
シリンダー法、赤外線加熱法がある。The heat treatment method in the present invention includes a hot air heating method, a heating cylinder method, and an infrared heating method.

ＦＴ以下では、ポリオレフィン系粒子層が膜化せずに、
眉間に間隙が存在するため、通気性の調整はできない、
又、ポリオレフィン系粒子が融着せず、不織シートと密
着しないため、不織シートから簡単に脱落する。The heat treatment temperature is higher than the MFT of the polyolefin particles and lower than the melting point of the nonwoven sheet.
Below FT, the polyolefin particle layer does not form a film,
Because there is a gap between the eyebrows, ventilation cannot be adjusted.
In addition, since the polyolefin particles do not fuse and adhere closely to the nonwoven sheet, they easily fall off from the nonwoven sheet.
ポリオレフィン系粒子のＭＰＴ以上に加熱することによ

ことにより互に融着し、その結果ポリオレフィン系粒子
が適度に粒子間の空隙の一部が失われ、その融着の程度
を調整することにより通気性が調整できることになる。By heating the polyolefin particles to a temperature higher than the MPT, the air permeability can be adjusted. By heating above the MFT, the polyolefin particles are fused together, and as a result, some of the voids between the particles are appropriately lost in the polyolefin particles, and air permeability can be adjusted by adjusting the degree of fusion.
ポリオレフィン系粒子の粒子径異なるもの、又、ＭＦＴ

可能である。Polyolefin particles with different particle sizes, and MFT
It is also possible to mix different materials, or to mix and use particulate materials having a higher melting point than the polyolefin particles.
