Description

[Detailed description of the device] << Industrial application field >> This device is an improvement of an umbrella with a synthetic resin film, which eliminates the unpleasant luster peculiar to chemical products and gives a chic high-class feeling. However, it relates to an umbrella with a light and strong umbrella beam.

<Prior art> A simple umbrella using a film such as vinyl as an upholstery material is well known. Because this kind of umbrella is weak in tearing due to its material, it requires a relatively large amount of material because a thick synthetic resin film is used, and it has the drawback of being heavier and more peculiar to chemical products. Since it has a cheap luster, it is often thrown away easily after use, so there are many problems from the viewpoint of resource saving.

<Problems to be solved> An umbrella that is lighter in weight than synthetic resin films and contributes to resource saving, yet has strong tear strength and is lightweight, yet has a high-class and heavy-weight feel that is not inferior to upholstered umbrellas. The challenge is to provide.

<Means for Solving the Problem> An ultrafine filament formed by coating a fusible polymer around the fusible polymer at random is randomly arranged and heat-fused to the top surface of a non-woven fabric (1). -Like reinforcing material (2) composed of strips obtained by coating a flexible polymer with a fusible polymer and stretching it, heat-sealing it, and further providing a synthetic resin laminate layer (3) on the upper surface of the reinforcing material The upholstery (4) is formed, and the upholstery (4) is covered with the umbrella frame (5).
It was stretched over.

<< Example >> FIG. 1 shows an umbrella (6) formed by stretching an umbrella upholstery (4) on an umbrella frame (5). Since the thickness of this upholstery material (4) is extremely thin, the thickness is extremely enlarged in the perspective view shown in FIG. In reality, the thickness is displayed in micron.

The filament (13) constituting the non-woven fabric (1) is melt-spun by disposing an easily fusible polymer (12) surrounding a hardly fusible polymer (11) as shown in an enlarged scale in FIG.
The filaments (13) are randomly arranged to form a thin layer (14) through a stretching process, in which the molecules are oriented in the axial direction, and the nonwoven fabric (1) is formed by heat fusion. Is formed. As the poorly meltable polymer, for example, polyester, and as the easily meltable polymer,
For example, polyethylene or the like is used.

The strip (24) serving as the reinforcing material (2) is woven in a lattice shape at appropriate intervals in each of the length and width, and is laid on the non-woven fabric (1) and heat-bonded to the non-woven fabric (1). To be done. As shown in FIG. 2, the vertical slip (2a) and the horizontal slip (2b) constituting the reinforcing material (2) are cross-shaped (2).
Although it overlaps with c), the overlapping condition may be a plain weave state as shown in FIG. Note that the slip (2
The width of 4) is about 1-2 mm.

As shown in the enlarged view of FIG. 4, the material of the slip (24) is made by coating the refractory polymer (22) with the fusible polymer (23) and stretching it in the axial direction. The array of molecules is axially oriented.

The slip (24) used here is a generic term for thin and long ones such as ribbon-shaped and filament-shaped ones. Also in this case, for example, polyester is used as the poorly meltable polymer, and polyethylene is used as the easily meltable polymer.

Further, so-called polylaminate mat processing is performed, in which the surfaces of the above-mentioned non-woven fabric (1) and lattice-shaped reinforcing material (2) are covered with a synthetic resin laminate layer (3).

For this synthetic resin laminate layer (3), for example, a laminate material of a matte synthetic resin (matte mat) formed by mixing polyethylene with ultrafine powder of ions + aluminum is used. The surface or the back surface of the laminate layer may be coated with the matting material.

The synthetic resin laminate layer may be provided on the nonwoven fabric (1) side.

Nonwoven fabric (1) made of the above materials, lattice reinforcing material (2)
The synthetic resin laminate layer (3) and the synthetic resin laminate layer (3) are laminated and integrated to form the umbrella lining (4).

The umbrella upholstery (4) is stretched over the umbrella bone (5) to form the umbrella (6).

The non-woven fabric and the grid-like reinforcing material may have the same color or different colors. For example, when a white non-woven fabric is used as the non-woven fabric (1) and a colored strip is used as the reinforcing material (2), a colorful lattice is provided. You can get a patterned umbrella.

Further, as the synthetic resin laminate layer (3), the above ions +
When a so-called matte mat, which is made by mixing fine aluminum powder, is used, it is excellent in infrared ray cutting and light resistance, and also helps prevent static electricity, and is also useful as a parasol.

<Effect of Device> This device has the following effects because it is configured as described above.

Since the non-woven fabric is laminated with a grid-like reinforcing material, it is excellent in tear strength, but requires less material than the synthetic resin film and is light in weight.

Since the non-woven fabric is used as a base material, compared to an umbrella made of a synthetic resin film, the reflected light rays are suppressed and the glitter does not shine, and an umbrella having a high-grade and heavy feeling can be obtained.
