Description

Description Nonwoven fabric laminate, method for producing nonwoven fabric laminate, and bag using nonwoven fabric laminate

The present invention relates to a nonwoven fabric laminate, a method for producing the nonwoven fabric laminate, and a bag using the nonwoven fabric laminate. Background art

Textiles, paper, films, etc. have been used for bags in the past, but bags using nonwoven fabrics made of thermoplastic resin have become popular in recent years because of their excellent price, strength, and bag-making properties. .

It is desired to improve the design of bags made of such nonwoven fabrics. Conventionally, nonwoven fabrics have been directly subjected to printing, aluminum deposition, or the like to impart design. However, the embossed nonwoven fabric has a problem that it is difficult to perform delicate printing, aluminum deposition, and other processing because the fibers are randomly arranged and the surface has irregularities. Further, when printing processing, aluminum vapor deposition processing, and the like are directly performed on the nonwoven fabric, there is a problem that the wear fastness is poor. Above all, when a nonwoven fabric made of a polyolefin resin was directly subjected to printing or the like, the wear fastness was particularly poor. Therefore, a method of dry laminating or extrusion laminating a design film, which has been designed and processed by printing, aluminum vapor deposition, etc., to a nonwoven fabric has been proposed, but the laminate obtained by this method has an embossed surface. However, there was a problem that the finish was hard.

In order to solve such a problem, there has been proposed a method of embossing a design film which has been designed by printing, aluminum deposition, or the like, and laminating the embossed film on a nonwoven fabric (Japanese Patent Laid-Open No. 5-13). No. 8 846, etc.).

However, in such a method, the design film must be laminated on the nonwoven fabric after embossing the design film, which has a problem that the manufacturing process is complicated. Ma Further, in this method, when the decorative film and the nonwoven fabric are laminated, the decorative film and the nonwoven fabric are sandwiched and adhered by a mirror plate. Therefore, after attaching a protective film on the design film and bonding the design film and the nonwoven fabric so that the embossed pattern of the design film will not be crushed, it is necessary to remove the protection film and perform other work. There is a problem that it takes time to manufacture the body.

An object of the present invention is to provide a nonwoven fabric laminate that is easy to produce, has good design properties, is embossed, and has excellent wear fastness, a method for producing this nonwoven fabric laminate, and a nonwoven fabric laminate. The purpose is to provide used bags. Disclosure of the invention

The nonwoven fabric laminate of the present invention has at least a first layer made of a nonwoven fabric made of a thermoplastic resin, and a second layer made of a design film made of a thermoplastic resin that has been subjected to design processing. It is characterized by being heat-embossed laminated.

The nonwoven fabric of the first layer is preferably 1 to 30 denier, particularly preferably 2 to 20 denier. If it is less than 1 denier, the surface is apt to fuzz. On the other hand, if it exceeds 30 denier, it becomes inferior in denseness.

Further, the basis weight of the nonwoven fabric is preferably from 5 to ²⁰⁰ g / m ² , and particularly preferably T lOO g / m ² . If it is less than 5 g Zm ² , the strength is inferior, and if it exceeds ²⁰⁰ g Zm ² , it becomes heavy, thick and hard, the handleability decreases, and the raw material cost also increases. The design film of the second layer may be a film generally used as a soft packaging material, and a polyolefin film suitable for heat lamination with a nonwoven fabric is particularly preferable. Furthermore, co-extruded films are particularly preferable in consideration of the heat laminating property with the nonwoven fabric.

The thickness of the design film is preferably from 5 to 400 m, more preferably from 10 to 200 m. Further, it is preferably 15 to 100 m. If it is less than 5 m, the strength will be insufficient and handling will be poor. On the other hand, when the thickness is more than 400 m, the material is too thick and inferior in handleability, and because it is too rigid, it is not suitable for use as a bag or the like, and the cost of raw materials increases. In the present invention having this configuration, since a film made of a thermoplastic resin is subjected to design processing instead of printing or aluminum deposition directly on the nonwoven fabric, it is possible to apply a delicate pattern or the like. It can be excellent.

Further, since a design-processed film is used, the wear resistance can be improved as compared with the case where printing is performed directly on the first nonwoven fabric.

Furthermore, in the present invention, the first and second layers can be hot-embossed and laminated at one time, which is different from a conventional case where only a design film is embossed and then laminated on a nonwoven fabric. A nonwoven fabric laminate that is easily embossed can be obtained without any trouble in production. In the present invention, the nonwoven fabric laminate preferably has a third layer made of a thermoplastic resin film or nonwoven fabric.

The thermoplastic resin film or nonwoven fabric of the third layer may be any one that is generally used as a soft packaging material. In order to give a clear feeling, the film may be a plain film, or may be printed for further improving the design.

Further, the third layer may be a nonwoven fabric in order to give an impression of the cloth to the nonwoven fabric laminate. When the third layer is made of a nonwoven fabric, the thickness is preferably 50 g Zm ² or less so that the decorative film can be seen.

In the present invention, since the third layer is provided on the design film, the design film is protected, and the wear fastness of the nonwoven fabric laminate can be further improved.

In the present invention, it is preferable that the design film is formed by printing or depositing aluminum on a thermoplastic resin film.

Printing on the film and vapor deposition of aluminum can be easily performed, so that no labor is required for manufacturing the nonwoven fabric laminate.

In the present invention, the first layer nonwoven fabric is preferably a spunbonded nonwoven fabric.

Spun-punched non-woven fabric is thin, high density and high abrasion resistance ぃ Non-woven fabric can be used. Also, as compared with other non-woven fabric manufacturing methods, for example, the melt blow method, the non-woven fabric manufactured by the spun pond method has an advantage that it is made of continuous filaments and hardly generates burrs.

In the present invention, the thermoplastic resin used for each of the layers is preferably a polyolefin-based resin.

The polyolefin resin has excellent heat laminating properties, and can be easily heat laminated by forming each layer of the polyolefin resin, and is suitable for bag making utilizing heat sealability. The method for producing a nonwoven fabric laminate of the present invention comprises a nonwoven fabric laminate having at least a first layer made of a thermoplastic resin nonwoven fabric and a second layer made of a design-processed thermoplastic resin design film. The method according to claim 1, wherein at least the two layers are simultaneously hot-embossed and laminated.

The hot emboss laminate has at least a pair of heating rolls, and one of the heating ports can be performed using a general hot embossing device embossed by engraving, etching or the like.

A variety of emboss patterns can be adopted, for example, a pattern in which concaves and convexes of irregularities are formed discontinuously in a dot shape, a lattice shape, and the like.

In the present invention having such a configuration, since the two layers are simultaneously subjected to the hot emboss lamination, the manufacturing process can be simplified as compared with the case of laminating after embossing each layer. In the present invention, it is preferable that the nonwoven fabric laminate has a third layer made of a thermoplastic resin film or nonwoven fabric, and the three layers are simultaneously hot-embossed and laminated.

Even if the non-woven fabric laminate has a third layer, the production of the non-woven fabric laminate is not troublesome because the three layers are simultaneously hot-embossed.

In the present invention, the hot embossed laminate is used when manufacturing the first layer nonwoven fabric. It is preferable that the second layer or the second layer and the third layer are laminated on each other, and the in-line processing of embossing is performed.

Here, in-line processing refers to laminating a second layer, or a second layer and a third layer on a web in which the resin of the first layer of nonwoven fabric has been opened, and using this as an embossing roll, hot enbossing This is a method in which the first layer of resin is thermally bonded while performing the following.

In this way, the production of the first layer nonwoven fabric and the hot emboss lamination can be performed simultaneously, so that the number of production steps can be reduced and the production cost of the nonwoven fabric laminate can be reduced. The bag of the present invention is characterized by being obtained by molding the above nonwoven fabric laminate.

The same functions and effects as those of the nonwoven fabric laminate described above can be obtained. In other words, it is possible to obtain a bag that has excellent design properties, high wear fastness, and is easy to manufacture. BRIEF DESCRIPTION OF THE FIGURES

Next, these are supplied between the emboss opening 27 1 of the hot embossing device 27 and the flat roll 27 2. The non-woven fabric 11 is formed by the hot embossing device 27, and the non-woven fabric 11, the decorative film 12 and the non-woven fabric 13 are hot-embossed and laminated to obtain a non-woven fabric laminate 1.

Although not shown, the nonwoven fabric laminate 1 thus obtained can be used as a bag by sewing and heat sealing. Therefore, according to the present embodiment, the following effects can be obtained.

Since the nonwoven fabric laminate 1 is made by processing a thermoplastic resin film instead of directly printing or depositing aluminum on the nonwoven fabric, it is possible to apply delicate patterns, etc. It can be excellent.

In addition, since the design-processed film 12 is used, it should have excellent wear fastness compared to the case of printing directly on the first nonwoven fabric 11. Can be.

Further, since the third-layer nonwoven fabric 13 is provided on the design film 12, the design film 12 is protected, and the wear fastness of the nonwoven fabric laminate 1 can be further improved.

Also, since the first layer nonwoven fabric 11, the second layer design film 12 and the third layer nonwoven fabric 13 are hot-embossed and laminated at the same time, only the design film is embossed as in the past. After that, as compared with the case where this is laminated on a nonwoven fabric, the production takes less trouble and the nonwoven fabric laminate 1 which has been embossed can be easily obtained. Furthermore, the decorative film 12 is a co-extruded film made of a polyolefin resin, and can be easily printed and aluminum-deposited, is easily laminated by heat, and requires time and effort to manufacture the nonwoven fabric laminate 1. do not do.

In addition, since the thickness of the design film 12 is set to 5 to 400, the strength It has a high degree of handling and does not require much effort in handling.

Since the non-woven fabric 11 is a spun-pound non-woven fabric, the non-woven fabric can be thin, high in density and high in abrasion resistance. Further, as compared with the melt blow method or the like, the nonwoven fabric produced by the spunbond method has an advantage that it is made of continuous filaments and is less likely to generate fluff.

In addition, the nonwoven fabric 11 has a denier of 2 to 20 and is less likely to generate fuzz on the surface, and can be excellent in denseness. Furthermore, since the basis weight of the nonwoven fabric 11 is 7 to 100 g Zm ^2, it has the strength necessary for handling and has an appropriate weight, so that it has excellent handling properties and manufacture the nonwoven fabric laminate 1. It does not take much effort. Since the third layer is made of the nonwoven fabric 13, the nonwoven fabric laminate 1 can be given the feel of a cloth. In addition, since the basis weight of the nonwoven fabric 13 of the third layer is 50 g Zm ² or less, the design film 12 can be seen through, and the nonwoven fabric laminate 1 having excellent design properties can be obtained. Furthermore, since the nonwoven fabric 11, the decorative film 12 and the nonwoven fabric 13 are made of a polyolefin resin having excellent heat lamination properties, they can be easily thermally laminated.

In addition, since the nonwoven fabric laminate 1 was manufactured by in-line processing, the production of the first nonwoven fabric 11 and the hot emboss lamination can be performed simultaneously, so that the number of manufacturing steps can be reduced and the nonwoven fabric laminate can be reduced. 1. The manufacturing cost can be reduced.

Furthermore, the bag obtained by sewing the nonwoven fabric laminate 1 has excellent design, high abrasion resistance, and can be easily manufactured. It should be noted that the present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved.

For example, in the above-described embodiment, in-line processing is performed. However, the present invention is not limited to this, and after each layer is formed, hot emboss lamination may be separately performed.

In the above-described embodiment, the first layer nonwoven fabric 11 is a spun-pound nonwoven fabric. However, the present invention is not limited thereto, and a nonwoven fabric manufactured by another method, for example, a nonwoven fabric manufactured by a hot air card method may be used. However, spun-pound nonwovens are thin, dense, and abrasion resistant. It has the advantage of being expensive.

Further, the design film 12 is printed and aluminum-deposited on a thermoplastic resin, but may be subjected to design processing by another method.

Furthermore, the nonwoven fabric 11, the decorative film 12 and the nonwoven fabric 13 are made of polyolefin resin, but are not limited to polyolefin resin, and may be made of thermoplastic resin. Those generally used as soft packaging materials are preferred.

In the above embodiment, the third layer of the nonwoven fabric laminate 1 is the nonwoven fabric 13, but may be a transparent film. In the case of forming a transparent film, a film generally used as a soft packaging material is preferable. In order to further improve the design of the nonwoven fabric laminate 1, the third layer may be a film that has been subjected to design processing such as printing. When a printed film is used, the printed surface is preferably a laminated surface in consideration of the fastness to friction.

Furthermore, although the nonwoven fabric laminate 1 has a three-layer structure, the present invention is not limited to this, and the nonwoven fabric laminate 1 may have a four-layer or more structure. The first-layer nonwoven fabric 11 and the second-layer design film 1 2 It may have a two-layer structure consisting only of the above.

Further, in the above-described embodiment, the heat embossing device 27 is a single-stage type, but is not limited thereto, and may be a multi-stage type. When the heat embossing device 27 is a multi-stage type, the immobilization of the nonwoven fabric 11 and the heat lamination can be performed separately, so that the laminating strength can be stabilized and the processing speed can be improved. The following experiment was performed to confirm the effects of the present invention.
