Conventionally, the raising method of a base material in which a polymeric elastic material is added to a sheet-like material is to buff the base material in a dry state at room temperature,
Brushing is normal. These require a large amount of grinding in order to make the nap on the sheet surface graceful, and it is necessary to set the sheet weight to a high value in advance. This has the disadvantage of causing short piloerection. On the other hand, there is a method in which a small amount of a smoothing agent containing oil is attached to a base material provided with an elastic body, and then ground and raised at room temperature in a dry state. Although these can produce elegant long naps, they cause clogging of the surface of the abrasive, making it difficult to obtain a product of stable quality, shortening the durability of the abrasive, and being economically disadvantageous. In addition, recently, Tokuko Sho 51-18556,
57-141023 (Japanese Unexamined Patent Publication No. 59-30955), there is a method of bringing a sheet-like material into contact with a rough surface in a fluid to remove fuzz. Although this method has the advantage of significantly increasing the number of times of contact with a rough surface in a short period of time, it is not suitable for grinding or raising a sheet-like material coated with a polymeric elastic material. In other words, in order to selectively remove the exposed polymer elastic body on the surface and generate fiber naps on the surface, the fluid velocity must be increased to increase the frictional resistance with the rough surface, or the rough surface must be Either the unevenness of the sheet must be made rougher, or the nozzle through which the sheet passes must be made narrower. Naturally, it is effective in softening the texture, but the binding force of the fibers by the polymeric elastic body decreases, resulting in a decrease in product strength. Furthermore, if the above-mentioned grinding conditions are relaxed, the nap becomes uneven, and in order to make the nap uniform, the number of circulations must be increased, resulting in a decrease in product strength.
In some cases, a peach phenomenon (a phenomenon in which fibers fall off due to friction, exposing the polymeric elastic body, resulting in an extreme drop in quality and physical properties) may occur, which can be a fatal defect for the product. Therefore, this type of method is extremely limited in the types of fabrics to which it can be applied.
本発明は上記欠点のない、効率的な研削量で、
製品特性を低下させず、優美な立毛を有するシー

The present invention has an efficient grinding amount without the above-mentioned drawbacks,
The present invention was finally arrived at as a result of extensive research into a method for raising sheet-like materials that does not reduce product properties and has elegant raised naps.

That is, in the present invention, when raising a base material in which a polymeric elastic material is applied to a sheet-like article, the base material is brought into a wet state, and then spread in the width direction, and further tensed in the length direction, and then ground and raised. The present invention relates to a method for raising a sheet-like material.
以下に本発明を更に詳しく説明する。 The present invention will be explained in more detail below.

細化処理を組合せて処理したシートである。 The sheet-like material mentioned here refers to a sheet made of a nonwoven fabric, a woven fabric, or a knitted fabric impregnated with an elastic polymer, preferably a sheet made of a fine fiber sheet impregnated with an elastic polymer.
More preferably, polyvinyl alcohol is added to the multi-component conjugate fiber sheet as suggested in Japanese Patent Publication No. 47-46887, or ultra-fine treatment is combined, either before or in a post-process to add the polymer elastic material to the multicomponent composite fiber sheet. This is a processed sheet.
高分子弾性体とは、ポリウレタンが典型例だが
ニトリルブタジエンゴム、ポリ塩化ビニル、ポリ
酢酸ビニル等であり、目的とする製品にあわせて
適宜、選択すればよい。 A typical example of the polymer elastomer is polyurethane, but other materials include nitrile butadiene rubber, polyvinyl chloride, polyvinyl acetate, etc., and may be selected as appropriate depending on the intended product.
高分子弾性体の含浸割合は、目的、用途によつ
て全く異なるので一概に規定する事は困難である
が、例えば、不織布の場合には15〜20重量％（対
繊維）、織物、編物の場合には１〜30重量％（対
繊維）であることが多い。 The impregnation ratio of the polymeric elastomer varies depending on the purpose and use, so it is difficult to define it unconditionally. In most cases, the amount is 1 to 30% by weight (based on the fiber).

言う。 The method of grinding and raising after making it into a wet state of the present invention is a method of passing a sheet-like object in water, squeezing it with a mangle, for example, to make the moisture content constant, and then grinding and raising the sheet-like object. A method of sprinkling steam on one or both sides of the material and then grinding and brushing, or in extreme cases, grinding and brushing in water, or a combination of these.

目安である。 The moisture content in a sheet in a wet state varies depending on the sheet weight, thickness, and type of polymeric elastomer used, and it is difficult to define it unconditionally. In order to obtain good and elegant pils, 50% by weight (based on the sheet) or more,
A tentative guideline is preferably 100% by weight (based on the sheet) or more.

添加してもよい。 Hot water may be used to increase the sheet temperature in methods other than steam injection. Rather, these methods ease the adhesion between the elastic polymer and fibers in the sheet, remove the elastic polymer on the surface of the sheet with a more efficient amount of grinding, and improve the surface quality. It is effective in generating piloerection. Further, a small amount of a lubricant such as an oil agent, a swelling agent for a polymeric elastomer, or the like may be forcibly added to the water used.

すればよく、特に限定されるものではない。 The raising treatment means include sandpaper, sand cloth, sand net, whetstone, steel brush, abrasive brush, sand roll, cloth cloth, cloth cloth, etc., and the method can be selected as appropriate depending on the intended use. Well, there are no particular limitations.
これらの起毛処理手段を用いて研削、起毛を行
なうにあたり、シート状物を拡巾し、かつ一定緊

くなり、研削斑、立毛斑を誘発し、極端な場合に
はシートの破断を発生し致命的なトラブルとな
る。 When performing grinding and napping using these napping treatment means, it is necessary to widen the sheet-like material and to carry out the process under constant tension. That is, when kept in a wet state, the sheet becomes soft and easily wrinkled, causing grinding spots and piloerection spots, and in extreme cases, the sheet may break, causing a fatal problem.
研削クリアランスが一定の場合シートの送り速
度と研削機の回転速度差が大きいほど研削効率は
高くなることは容易に推定できるが、同時に高分
子弾性体のみならず、繊維の切断も激しくなる。
おどろくべきことに本発明法では、この速度差を

削材の摩擦が緩和され、高分子弾性体の研削率が
高くなり、少量の研削量でシート状物表面に優美
な立毛を発生させることが可能である。 When the grinding clearance is constant, it can be easily estimated that the larger the difference between the sheet feed speed and the rotational speed of the grinder, the higher the grinding efficiency, but at the same time, the cutting of not only the polymer elastic body but also the fibers becomes more severe.
Surprisingly, in the method of the present invention, even if this speed difference is increased, the friction between the fibers and the abrasive material is alleviated by the intervening water molecules, and the grinding rate of the elastic polymer body is increased, allowing a small amount of grinding to be achieved. It is possible to generate elegant naps on the surface of a sheet-like object.
湿潤状態での研削は研削材表面に付着した研削
粉が除去しにくいものであるが、本発明法では、
研削材表面に圧空または高圧水をふきかけること

なわち、本発明法が、高分子弾性体の研削率が高
く、研削粉中の繊維量が減少し、研削機表面の凹
凸部にまとわりつきにくいものと推定される。 Grinding in a wet state makes it difficult to remove grinding powder adhering to the surface of the abrasive material, but with the method of the present invention,
It can be easily removed by spraying compressed air or high-pressure water onto the surface of the abrasive material. That is, it is presumed that the method of the present invention has a high grinding rate of the polymer elastic body, reduces the amount of fibers in the grinding powder, and is less likely to cling to the irregularities on the surface of the grinder.

での起毛方法を組合せて行なつてもよい。 In order to adjust the napping length of a sheet-like material to a desired length or to remove in advance the polymeric elastic material attached to the sheet surface, the present invention's wet napping method and the conventional napping method are used. A combination of raising methods at room temperature and in a dry state may be used.
