Description

[Detailed description of the invention] (Industrial application field) The present invention is a packaging and protective covering material, which is made by interposing a nonwoven fabric between a textile and a required covering member, and laminating and adhering each of them. This invention relates to composite members used for interior decoration wall fabrics, etc.

(Prior Art) Conventionally, similar technologies have been proposed in Japanese Patent Publication No. 33-2488 and Japanese Utility Model Publication No. 48-4227.

The former proposed method is a moisture-resistant laminate that maintains its own shape and is substantially impermeable to moisture, which is made by alternately laminating at least one layer of polyethylene film and at least one layer of polyalkylene fiber fabric and adhering them to each other. It is the body.

The latter is a synthetic resin filament made by fusing a synthetic resin thin film to the surface of a fabric woven with synthetic resin flat filaments as warp and warp threads, and pasting a backing paper to this thin film with an adhesive. The fabric is woven by

(Problem to be solved by the invention) In the former case in the prior art, while it exhibits excellent properties when used as a packaging covering material, on the other hand,
Since properties such as flexibility and elasticity are rather poor, there is a drawback that when used as a protective coating material, it cannot be used for some articles, such as articles whose surfaces are easily damaged.

In the latter case, a backing paper is attached to one side of the fabric made of flat filaments made of synthetic resin, so it can be used as wallpaper, but it is thin and has no elasticity, so it is difficult to create a solid wall. Furthermore, since it is thin and made of only woven fabric and paper, its insulation properties, which reduce the influence of outside temperature on indoor air, are inevitably inferior, and when used as a bag, it cannot store items with a high moisture content. Its scope of use is severely restricted,
Also, since it does not have much elasticity, it also has the disadvantage that it cannot be used in other fields that require this characteristic, as in the former case.

(Means for Solving the Problems) The present invention has been made by focusing on such conventional problems, and involves interposing a nonwoven fabric between the woven fabric and the required covering member, and laminating and bonding each of them. The purpose of the present invention is to solve the above problems by imparting excellent flexibility, elasticity, heat insulation properties, etc. to the composite member and dramatically improving its properties by forming a composite member.

The present invention consists of a woven fabric made of natural fibers or synthetic fibers, either alone or in an appropriate blend;
A nonwoven fabric made of either recycled fiber or synthetic fiber is interposed between the covering member made of the required material, and a nonwoven fabric formed by laminating and adhering each of them with synthetic resin such as polyethylene is interposed. It is a composite member.

(Function) Composite members have excellent flexibility, elasticity, and heat insulation properties because they have a nonwoven fabric interposed between the fabric and the covering member. It can be widely used in other fields.

Further, when manufacturing a thick composite member, it can be made extremely easily by increasing the thickness of the nonwoven fabric, and since the price of the nonwoven fabric is low, the cost does not increase.

(Example) The present invention will be described in detail below based on FIGS. 1 and 2 showing a first example. 1 is made of a blend of cotton fiber and polyamide synthetic fiber, and is woven and has a thickness of approx.
0.3 mm woven fabric, 2 is a non-woven fabric made of polyamide synthetic fibers with a thickness of about 0.4 mm, and 3 is a polyethylene film with a thickness of about 20 μm, cut into thin strips of about 4 mm, and used as warp and warp threads. This is a covering member made of woven fabric with a thickness of approximately 0.05 mm.

In step 4, polyethylene melted at about 250° C. is poured between the woven fabric 1 and the nonwoven fabric through a thin film 5 while applying pressure to bond them together in a so-called laminate, and then a layer is placed between the exposed surface of the nonwoven fabric 2 and the covering member 3 in the same way as before. This is a composite member with a thickness of approximately 0.75 mm, which is formed by laminating and adhering the covering member 3 by applying pressure to the three members while flowing polyethylene through a thin film 5 using a conventional method. The thickness of the thin film 5 becomes extremely thin due to the pressurization of the woven fabric 1, the nonwoven fabric 2, and the covering member 3 during lamination and bonding, to the extent that it does not significantly affect the thickness of the composite member 4.

In this case, the composite member 4 comprises the textile 1 and the covering material 3.
Since the nonwoven fabric 2 is interposed between the nonwoven fabric 2 and the nonwoven fabric 2, it has excellent flexibility, elasticity, and heat insulation properties, and can be used in other fields where conventional products cannot be applied, such as having excellent heat insulation properties. It can be used in a wide range of applications, including decorative wall cloth that gives a wall a solid feel, protective covering materials for items whose surfaces are easily damaged, and materials for various types of bags such as bags and backpacks.

In addition, since the composite member 4 has a coating material 3 made of woven fabric laminated and bonded to one side, the mechanical strength such as the weak tensile strength and tear strength of the woven fabric 1 and the nonwoven fabric 2 is significantly improved, and it can be used for heavy bags. , the scope of its use can be further expanded to include packaging bags.

In addition, in the composite member 4, since the pores on both the bonding surface of the fabric 1 and the bonding surface of the nonwoven fabric 2 are blocked by polyethylene when laminated and bonded, the air permeability and moisture permeability are low, and the heat insulation properties of the nonwoven fabric 2 are also reduced. It is possible to improve this and develop new demand.

FIG. 3 showing a second embodiment of the present invention will be described below. 6 is made of cotton fiber and has a thickness of about 0.3
7 is a non-woven fabric with a thickness of about 0.4 mm made of recycled cellulose fibers, 8 is a covering member made of kraft paper with a thickness of about 0.1 mm, 9 is a woven fabric 6, a non-woven fabric 7,
This is a composite member having a thickness of approximately 0.8 mm, in which the covering member 8 and the covering member 8 are laminated and bonded in the same manner as in the first embodiment.

In this case, since the composite member 9 uses kraft paper as the covering material 8, the composite member 9 of the first embodiment
Although mechanical strength such as tensile strength is inferior, other effects are almost the same as in the first embodiment.

In each of the above embodiments, the fabrics 1 and 6 are
Although the example used a blend of cotton fiber and polyamide synthetic fiber, and the second example used a knitted fabric of cotton fiber alone, the invention is not necessarily limited to this, and can be used depending on the purpose of use. Therefore, natural fibers such as cotton and wool, or synthetic fibers such as polyamide, polyvinyl alcohol, polyacrylonitrile, polyester, and polypropylene may be used alone or in an appropriate blend. In addition, although the nonwoven fabrics 2 and 7 were made of polyamide-based synthetic fibers in the first embodiment and cellulose-based recycled fibers in the second example, they may also be used in reverse, and non-woven fabrics other than cellulose-based fibers may be used. Materials made from recycled fibers or polyester synthetic fibers may also be used. In addition, as covering members, flat filaments made of polyethylene film were used in the first embodiment, and kraft paper was used in the second embodiment, but instead of polyethylene film, synthetic resins such as polyamide, polyester, and polypropylene were used. Instead of kraft paper, other paper or synthetic paper having mechanical strength equal to or higher than kraft paper may be used for the flat filament made of film.

Moreover, the composite members 4 and 9 include woven fabrics 1 and 6, nonwoven fabrics 2,
7 and the covering members 3 and 8 are laminated and bonded using synthetic resin such as polyethylene, but instead of laminating and bonding, a suitable adhesive may be applied and bonded by applying pressure. good.

By increasing the thickness of the intervening nonwoven fabrics 2 and 7, the composite members 4 and 9 can significantly improve their heat insulation properties, and further improve their original excellent flexibility, elasticity, and non-thermal properties. Combined with its light weight,
It is possible to form special materials such as those for cold protection.

(Effect of idea) Since the present invention has the above configuration, it has the following effects.

(1) Since the nonwoven fabric is interposed between the fabric and the covering material, it has excellent flexibility, elasticity, heat insulation properties, and moisture impermeability, so it can be used as packaging and protective covering materials, and wall decoration materials. It is widely used and contributes to sales expansion of companies.

(2) Since the nonwoven fabric is interposed between the fabric and the covering member, it has excellent flexibility, elasticity, moisture impermeability, and durability, so it can be used in other fields where conventional fabrics could not be applied, such as bags. It can be used as a material for various bags such as , bags, etc., and contributes to increasing corporate profits.

(3) By increasing the thickness of the nonwoven fabric, it is possible to form special materials for lightweight cold protection, etc.
It is possible to develop new demand and contribute to increasing sales of companies.
