ことのできるものが食堂などで汎用されている。2. Description of the Related Art In general, a cloth for cloth or embroidered is used for a table cloth or an underlay of a vase. However, once the cloth or the lace is dirty, it must be washed and should be washed again. Sometimes it is not possible to easily remove dirt. Therefore, a woven fabric or a lace fabric is overlaid with a transparent, sheet-like material and can be easily wiped off even if it is dirty, which is commonly used in cafeterias and the like.
【０００３】一方、最近、バッグの中身を見せるように

あっても型くずれが生じにくいからである。On the other hand, recently, a sheath-type bag, a document case, an accessory case, etc., in which the contents of the bag are shown, have become popular. For such bags and accessory cases,
A transparent film made of hard vinyl chloride is often used as a part or the whole thereof. This is because the rigid vinyl chloride has a large rigidity, and even when it is used in a bag or the like, the shape of the vinyl chloride is not easily lost.

品を切望している。A table cloth made by laminating a transparent sheet material on a woven fabric or a lace fabric is certainly easy to wipe off stains and is easy to handle, but lacks a high-class appearance in its appearance. Cannot be denied. Therefore, in high-class restaurants and hotels, textiles and lace fabrics are still used in many cases. These industries are eager for alternatives that are high quality and easy to handle.

た場合には切り口が一種の刃物として作用し、人の手指
を負傷せしめることもあるのである。Although hard vinyl chloride used for bags and the like is excellent in shape retention, it is weak against the force applied at the time of bending, and for example, the opening / closing portion of the bag or the fold portion of the body of the bag. For example, there is a drawback that a portion that is repeatedly or constantly bent is deteriorated and easily damaged. A damaged bag is not only unpleasant to look at, but is not preferable in terms of personal safety. That is, due to its rigidity, hard vinyl chloride may cause the cut end to act as a kind of blade when it is broken, and may injure a human finger.

型性が担保されないため、製造コストやデザイン上の制
約を受けるという問題がある。In order to avoid such inconvenience, it is desirable to use soft vinyl chloride. However, since the soft vinyl chloride does not guarantee the shape retention when it is made into a bag unless the thickness is considerably increased, the manufacturing cost and There is a problem of being restricted by design.

The continuous filaments are adhered to each other at each intersection. By taking such a form, a kind of "mesh" is formed between the continuous filaments, the transparency of the sheet is secured by this mesh, and the sheet feels high-class, cool and clean.

り、加工時にシートが破れる恐れもある。In the present invention, the parallel light transmittance is adopted as a measure showing the degree of density of the mesh. The non-woven reticulated sheet of the present invention preferably has a light transmittance of 10 to 60%. If it is less than 10%, the mesh is dense and the sheet cannot be said to be a mesh sheet, and the transparent effect desired by the present invention cannot be exhibited. Further, the smaller the parallel light transmittance, the more the amount of resin constituting the sheet is used, so that the rigidity of the sheet becomes too large, which makes it difficult to process into a bag or the like, or is not economical. Further, if the parallel light transmittance exceeds 60%, the mesh formed will be too coarse, resulting in a markedly poor design. In addition, since the mesh becomes coarse, that is, the number of bonding points between continuous filaments is reduced, the strength of the entire sheet becomes small, and the sheet may be broken during processing.

るといった問題が生じる。The continuous filaments forming the non-woven mesh sheet of the present invention preferably have a diameter of 0.5 to 2 mm.
If the diameter is less than 0.5 mm, each continuous filament becomes too thin, and thus the curved pattern or mesh formed by the continuous filament cannot be clearly recognized. Further, as described later, there is also a problem that the coloring effect is not sufficiently exhibited even when the continuous filament is colored in two or more colors. Further, as the diameter becomes smaller, the strength of the filament itself becomes smaller, so that the strength of the entire sheet becomes smaller, and the sheet may be damaged by the force applied during processing or during use. Also, the diameter is 2mm
If it exceeds, the rigidity of the sheet becomes too large, and when the sheet is bent, cracks or breaks occur, or even if cracks do not occur, the folded portion is whitened and the appearance is impaired.

Acrylic acid copolymer, ethylene-ethyl acrylate copolymer, ethylene-methyl methacrylate copolymer, ethylene-ethyl methacrylate copolymer, ethylene-methyl methacrylate-acrylic acid copolymer, or styrene -Butadiene rubber and the like are preferred. Among them, olefin polymers such as ethylene-vinyl acetate copolymer and styrene-butadiene rubber are most preferably used because of their high transparency and good color development with pigments.

となる。Even if the non-woven reticulated sheet is composed of colorless and transparent continuous filaments obtained by spinning the raw material synthetic polymer as it is, it gives a high-class feeling, a refreshing feeling and a clean feeling, and exhibits an excellent design effect. However, by coloring the synthetic polymer, it becomes more interesting and rich in design. For example, if a little red or blue coloring agent is mixed, a transparent and beautiful sheet can be made, and if a white coloring agent is mixed, the continuous filaments become semitransparent and the sheet has a shielding effect. Can be obtained. Further, the sheet can be colored in two or more colors, and in that case, a stained glass-like sheet with a high-grade feeling is obtained.

By applying a pressure treatment using the roll (13), the continuous filaments (2) are flattened, and the nonwoven reticulated sheet (1) of the present invention as shown in FIG. 2 can be obtained. At the place where the intersections (3) of continuous filaments were concentrated or close to each other in the sheet before pressurization, flattening formed a large number of continuous filaments (2) into a pool (4). However, in the present invention, a non-woven reticulated sheet having such a pool is considered to be included in the scope of the present invention. Since the pool portion gives an accent to the sheet, a net-like sheet having an interesting appearance can be obtained by positively making a large number by utilizing its design effect.

い。The non-woven reticulated sheet of the present invention thus obtained is easy to handle as a sheet because the continuous filaments are flat, and is stable even when a vase or the like is placed on it. The basis weight of the non-woven reticulated sheet is preferably 50 to 1000 g / m 2 from the viewpoint of strength and handleability.

０ｇ／ｍ2 、厚みは０．９mmであった。First, the transparent EVA used in Example 1 was spun from the spinneret in the same manner as in Example 1, and the continuous filaments were collected and self-fused. Then, while the continuous filaments did not solidify, a 0.1 mm thick transparent film made of soft vinyl chloride was sent out and laminated on the accumulated continuous filaments, and immediately the linear pressure was reduced to 0 using a smooth roll. By pressing at 0.6 kg / cm, the continuous filament was flattened, and at the same time, the transparent film and the continuous filament were integrated by utilizing the fusion force of the continuous filament. The non-woven reticulated sheet in the composite sheet thus obtained has a basis weight of 600 g / m 2 , its parallel light transmittance is 25%, and the total weight of the composite sheet is 76.
The thickness was 0 g / m 2 and the thickness was 0.9 mm.
