The present invention relates to a method for manufacturing a reinforcing material for laminated sheets reinforced with fabric. More specifically, a sheet-like hot melt adhesive is heated and laminated on a woven or knitted fabric having a density corresponding to the required degree of reinforcement, continuously after the production of the woven or knitted fabric, and then cooled and rolled up to create a laminate with the desired strength. The present invention relates to a method for producing a reinforcing material for obtaining. Conventionally, when manufacturing laminated materials reinforced with fabric,
Generally, a method has been widely used in which a fabric and a material to be laminated are supplied separately, an adhesive is applied to one or both, and the fabric and the material to be laminated are laminated by pressure using a nip roller. This method has the great advantage of being able to increase speed, have uniform quality, and have low processing costs. The disadvantage is that a fabric that does not bend must be used. Therefore, the fabric to be supplied is woven to a density that prevents slipping or bending, or is woven to a relatively coarse density.The fabric is then coated with a solution-based or emulsion-based resin, or subjected to treatments such as dipping. A method is used in which the dimensional stability is improved by drying to remove the solvent or moisture, and then the materials are laminated. The relatively coarse density referred to here refers to the warp density per 2.54 cm of fabric as nE and the weft density as nF, the warp thickness in English cotton count as N E , and the weft thickness as N E and weft thickness as expressed in English cotton count. N F
When nE/√ E +nF/√ F value K is 21 to 24
For fabrics with K≦20, weaving is possible to a certain extent, but as the density becomes coarser, slips and bending become more likely to occur when the fabric is used as a reinforcing material for laminated sheets. , it becomes almost impossible to handle the fabric without changing its shape. Therefore, in handling, emphasis is placed on the dimensional stability of the fabric used as a reinforcing material, and woven and knitted fabrics with high density and excessive strength are used, which naturally results in a large basis weight. . On the other hand, for laminated materials that require extreme weight reduction, such as membrane materials for air membrane structures and balloons, the strength should be set to the required value and the reinforcing material should have as small a basis weight as possible. For some reason, there are limits to lowering the density. It is also possible to apply a solution-based or emulsion-based adhesive during the fabric manufacturing process, but these methods require a rapid evaporation process by heating the solvent or water. Shrinkage due to swelling and evaporation of the fabric and associated dimensional changes occur.
Furthermore, the amount of adhesion increases or decreases due to changes in the adhesive over time,
Due to the occurrence of uneven shrinkage, etc., it has become extremely difficult to manufacture uniform fabrics. In view of the current situation, the present inventors have conducted extensive research and have arrived at the present invention. In other words, this is a method for manufacturing a reinforcing material for a laminated sheet made of a fabric whose yarn density is so coarse that it cannot be used as a reinforcing material for lamination processing as it is, and the warp density per 2.54 cm is nE, When the weft density is expressed as nF, the warp thickness expressed in English cotton count as N E and the weft thickness as N F , nE/
√ E + nF / √ A coarse density fabric with a value of 20 or less is woven and knitted without being rolled up once.
The fabric is continuously supplied from a manufacturing device such as a loom or a knitting machine to a heating zone without changing the manufactured shape, and at the same time a sheet-like hot melt adhesive is supplied to the heating zone, This method of manufacturing a reinforcing material is characterized in that the adhesive is melted by a method, then cooled, and then the adhesive-coated fabric is wound up. The present invention will be explained in detail below based on the drawings. FIG. 1 schematically shows the manufacturing process of reinforcing materials for laminated sheets, and FIG. 2 shows an adhesive laminating apparatus shown within the dotted line frame in FIG. 1. Creel 1
The warp sheet 110 drawn out in a uniform manner from the warp sheet 110 is uniformized in tension with a nip roll 102, and then is formed into a fabric 1 in a loom 103, and is supplied to a laminating device 104 through a surf roller 108. The fabric 1 supplied from the loom 103 is sent to the hot rolls 6 and 6', and at the same time, a sheet-like hot melt adhesive is supplied from the adhesive supply roll 17 via the guide roll 4. As the sheet-like hot-melt adhesive, a non-woven fabric-like hot-melt adhesive or a film-like hot-melt adhesive is suitable. The heat rolls 6, 6' are pressurized by a pressure adjustment handle 15 and are driven by friction with a flat belt 10 driven by a motor 14 via a transmission 13, and the woven fabric is heated. The sheet hot melt adhesive is melted and laminated to the fabric at a rate commensurate with the production rate of the fabric and the thermal shrinkage of the fabric caused by the hot rolls in order to feed it to the heating zone without changing its shape.
The adhesive-coated fabric leaving the hot rolls 6, 6' is naturally cooled at room temperature and wound onto a winding roll 109.
The adhesive-coated fabric produced in this way has extremely excellent dimensional stability even when the density is low. Although the fabric obtained as described above is not shown in the figure, it is subjected to a commonly used laminating machine together with a laminated sheet without applying an adhesive.
By passing through a heating zone and a pressure roll, a laminate reinforced with a reinforcing material made of the fabric obtained according to the invention can be obtained. In addition, if even greater adhesive strength is required,
If the fabric obtained by the method of the present invention is laminated with a material to be laminated using an ordinary laminator that applies adhesive, it is possible to obtain a laminated material with coarse density and small basis weight, but with high adhesive strength. can. Example 1 Both warp and weft are polyester filament yarn
After weaving using 500 denier 95 filament with a yarn density of 23 threads per 2.54 cm (K = 14.11), it was continuously fed to a laminating machine and used as an adhesive with a melting point of 115 °C and a weight of 25 g per 1 m2. Using a polyester non-woven hot melt adhesive,
Hot melt lamination was carried out at a speed of about 0.2 m/min using a heated roll whose surface temperature was set at 140°C. Then, it was cooled at room temperature for about 10 minutes and then wound up into a roll. (Fabric A) The warp and warp yarns in the fabric are not curved and are orthogonal with extremely high precision, and the weight is light at 130g/ m2 .
Useful as a reinforcing material for laminated sheets. On the other hand, the slipping resistance (g) of the above-mentioned Fabric A, Fabric B which is a gray fabric of Fabric A, and Fabric C obtained by dipping Fabric B with a water-soluble urethane resin and curing it at 150°C for 3 minutes, respectively, was determined by the method of JIS1096. Table 1 also shows the results of bending resistance measured using a cantilever method.

The reinforcing material obtained by the method shown in Example 1 was subjected to a film laminator at 140°C without using an adhesive.
When passing through a heated sol set to After cooling, the resulting laminated material is rolled up into rolls, and the warp and weft of the reinforcing fabric are not curved and are orthogonal with extremely high precision, which increases the adhesive strength between the fabric and the film.
As a result of measurement according to JIS 6854, the value was 0.95 kg/cm, and the weight was 150 g/ m2 , making it a lightweight and strong laminated sheet, which was excellent for use in air membrane structures and balloons. .
