本発明は、起毛を施したポリプロピレン繊維からなる不
織布基材にポリプロピレンシートをサーマルラミネート
した複合シートの製造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a composite sheet in which a polypropylene sheet is thermally laminated onto a nonwoven fabric base material made of raised polypropylene fibers.
従来、ポリプロピレン（以下、ＰＰと略ス）繊維で構成

。しかし、前記基材は、保管や運送時１ｃおける積み重
ねｋより。Conventionally, base materials made of nonwoven fabrics made of polypropylene (hereinafter abbreviated as PP) fibers with twisted threads of PP, nylon, etc. are lined by laminating a PP sheet. However, the base material is stacked more than 1k during storage and transportation.
しわや起毛の異方向倒れを発生する。従って。This causes wrinkles and naps to fall in different directions. Therefore.

の方法では、しわはある程度解消することかできるか。In thermal laminate 1cllL, it is necessary to take measures to eliminate the aforementioned wrinkles and naps falling in different directions. In the conventional method, a PP sheet extruded from an extruder is cooled and guided to a cooling roller, and at the same time the base material is guided under tension to a cooling roll for thermal lamination. Is it possible to eliminate wrinkles to some extent with this method?

支障を来たす場合かある。Further, the wrinkles on the base material disappear depending on the magnitude of the tension force k, or when the tension force is applied at intervals of the number + a1, and if the tension force is applied more than this, the wrinkles will not disappear. Placing an expander roll or the like for applying tension to the base material within several tens of countries from the lamination point may cause problems in the structure of the equipment.

複合シートの製造法を提供するものである。The present invention is a nonwoven fabric base material K made of brushed PP fibers.
To provide a method for manufacturing a composite sheet that can reliably correct wrinkles and naps that occur in different directions when PP sheets are thermally laminated.

る。In order to achieve the above objects, 1 the present invention introduces a PP sheet 2 extruded from an extruder 1 into a gap of 4.5 degrees between cooling rolls, and at the same time introduces a nonwoven fabric base material 6 made of PP fibers subjected to napping.
When introducing the material into the gap between the cooling rolls 3, 4 and 5 for thermal lamination, the following treatment is carried out in advance.

定方向に揃えられること番ζなる。That is, prior to lamination, tension is applied to the nonwoven fabric base material 6 using the Tenseen roll 7I, and in this state, it is guided to a heat roll 8 having unevenness in a certain direction, and the raised surface is passed through the heat roll 8.
It is heated by coming into contact with the uneven surface of the Nonwoven fabric base material 6
The wrinkles generated by winding the nonwoven fabric base material 6 are removed by thermal expansion caused by heating the nonwoven fabric base material 6 in a taut state. Further, the raised fluff that has fallen in a different direction is forced to be aligned in a certain direction due to the unevenness of the surface of the hot roll 8 in a certain direction.
次に１本発明の詳細な説明する。Next, one aspect of the present invention will be explained in detail.

When thermally laminating a m-wide nonwoven fabric base material onto a 2-inch thick PP sheet, the following steps were carried out in advance. That is, 1 table (i
The non-woven fabric base material was brought into contact with a surface temperature of 130 DEG C. and a diameter of 300 mm with an unevenness of jKα3 to α6 m and a tension of 6 oH/m, and then moved to the next lamination point. The resin temperature at the time of lamination was 150°C.

かつぶれるので好ましくない。If the temperature exceeds 155° C., the PP twisted yarn becomes fine and large, causing naps or crushing, which is not preferable.

極めて大なるものである。As described above, according to the present invention, when thermally laminating a backing material to a nonwoven fabric base material having a nap, it is possible to reliably remove wrinkles in the nonwoven fabric base material and fall of the nap in different directions to produce a good composite sheet. What it can do is that its industrial value is extremely great.
