紙、合成紙、不織布、フィルム等のシート杖の支持体に
発泡性マイクロカプセル含有層を設けてなるシートは、
その強い摩擦抵抗を生かして例えば、生理用ナプキン、
使い捨ておむつ、包帯等の衛生、医療用品；ティッシュ
、敷物等の家庭用雑貨；座席のヘッドレスト、アームレ
スト、枕カバー等のカバー類；テーブルクロス、トレイ
（盆）用ナプキン等のクロス類；シーツ、マント類等
の広い分野への応用が期待されている。A sheet formed by providing an expandable microcapsule-containing layer on a sheet support such as paper, synthetic paper, nonwoven fabric, or film is as follows:
Taking advantage of its strong frictional resistance, for example, sanitary napkins,
Sanitary and medical supplies such as disposable diapers and bandages; Household goods such as tissues and rugs; Covers such as seat headrests, armrests, and pillowcases; Cloths such as tablecloths and tray napkins; Sheets and cloaks It is expected that it will be applied to a wide range of fields such as the following.

用される。The foamable microcapsule-containing layer of such an anti-slip sheet is usually formed by two steps: smearing a coating liquid containing foamable microcapsules on a support, and heating the smeared layer to foam the capsules. A coating machine equipped with a heating device, such as a hot air drying zone, is generally used for both steps.

形からくる皺が発生し良好な防滑性シートが得られない
ことが多い。However, when manufacturing this anti-slip sheet, it is necessary to heat the sheet at least in the foaming process to a temperature at which the membrane material of the expandable microcapsules can sufficiently plasticize, so manufacturing may be difficult depending on the material and thickness of the support. It can be difficult. For example, if a synthetic paper, film, or nonwoven fabric made of polyethylene, polypropylene, etc., which is a base material that easily expands and contracts with heat, is used as a support, wrinkles will occur due to the deformation of the support, making it difficult to obtain a good anti-slip sheet. It is often not possible.
本発明は、如何なる支持体を用いても皺が発生すること
のない防滑性シートの製造方法の提供を目的とする。An object of the present invention is to provide a method for producing an anti-slip sheet that does not cause wrinkles no matter what type of support is used.

The present inventors have found that this can be made possible by doing so, and that there is almost no inhibition of anti-slip performance due to the feared decrease in capsule foaming efficiency due to pressurization, and the present invention has been completed.

A coating solution obtained by adding and mixing 19 parts of Hysilite H-42 (manufactured by Showa Denko K.K.) was applied to a 30 μm unstretched polypropylene film using a percoter so that the dry weight was 7 g/rd. Note that the drying zone of the bar coater was set at 70°C, and the capsules on the smear sheet were hardly foamed.

３０ｋｇ／−であった。Subsequently, the sheet was passed between a metal roll heated to 150° C. and a cotton roll to foam, resulting in an anti-slip sheet with no wrinkles at all. Incidentally, the pressure for the treatment was 30 kg/-.

られたシートには極めて多くの皺が発生した。Comparative Example A smear sheet obtained in the same manner as in the example was placed in a drying zone of 1.
Although the sheet was passed through the coating machine set at 50° C. again to cause foaming, the resulting sheet had an extremely large number of wrinkles.
