Description

A material laminating processing device

The present invention relates to a laminate processing apparatus for bonding a thin synthetic resin film to a fabric.

Looking at the general conventional laminating processing method and apparatus in the process step shown in Figure 1 as follows.

First, in the case of the 2-layer work in which the film is adhered to one side of the fabric, the <1> release paper (2) is prepared, the <2> primary skin layer (3) is coated, <3> dried, and <4> fabric (1) 2) Coating the adhesive layer 4 on the skin layer 3, <5> drying, winding after <6> fabric 1, <7> process movement, <8> maturation (24) Time, 80 ° C.), <9> process movement, peeling removal of the release paper 2 from the <10> fabric 1, <11> process movement, <12> water repellent treatment, and <13> inspection.

In the case of the 3 layer work laminating one surface of the fabric 1 and then laminating another fabric 1a thereon, the process proceeds to the above step <10>, followed by the arrangement and preparation of the laminated fabric. 12> Laminated fabric is coated with the adhesive layer 4 'again, <13> adhesive coated on the other fabric (1a), <14> large winding, <15> process movement, <16> inspection and the like.

In the conventional laminating process, the process itself has a very complicated disadvantage, and in the case of a strong water repellent process, it is difficult to maintain the adhesion between the fabric and the film. Particularly in the case of a fabric composed of filament yarn, it is difficult to work. In the case of laminating by pre-water-repellent processing, the process should be done by lowering the water repellency to 60% -70%, and in case of difficulty, the post-water-repellent processing should be done after laminating. It is.

In addition, according to the conventional method described above, since the laminating is performed after drying the adhesive layer, it is very difficult to obtain adhesive strength in the case of the water-repellent fabric, and the film is formed on the fabric by a general coating process (direct coating method, wet coating method, etc.) When laminating rather than water resistance and moisture permeability, the main point is to give the softness of the fabric. However, since the adhesive is composed on the whole surface of the fabric, the touch is softer than the product with general coating, but there is a disadvantage that there is a lot of hardness. will be.

In addition, since the coating of the skin layer and the adhesive layer more than two times on the release paper, it takes a lot of cost, such as the chemical material according to the coating, and because the secondary adhesive layer is formed, a aging process requiring time and high temperature is required. will be.

Therefore, the conventional laminating process will be referred to as a costly and time-consuming irrational method due to the complicated process and apparatus as described above.

In the case of lamination and lamination of the 3 layer method using a stretch fabric, the fabric area (especially the width) decreases due to the tension given to the fabric (shrinkage). In the sewing process, which is a process, the shape of the clothes is changed by sewing, so the garment may not be completed.

The present invention devised by the above problems to meet the required function by forming a minimum film film, in particular to change the front bonding method of the adhesive layer to a partial bonding method using a mesh or dot roller, When processing materials with high water repellency and elasticity, it is possible to obtain sufficient adhesive strength and very smooth processing fabric, and to secure sufficient moisture permeability and shrinkage rate compared to the quality by the existing methods, and in particular, due to the drastic reduction of the process. The aim is to reduce costs such as investment costs and to significantly improve production efficiency.

The present invention, in the laminating work on the fabric, when using the skin layer coating on the release paper to form an adhesive layer for adhering the fabric, do not form an adhesive layer on the entire surface of the fabric, but using a mesh or dot-type coating roller The adhesive layer is formed by the partial bonding method, and the installation structure can be very simple and efficient by improving the installation structure such as installing two overlapping devices in succession, and the fabric reduced by continuously installing the netdryer. Is to restore the width of.

First, the present invention will be described in detail with reference to the process chart shown in FIG. 2 as follows.

Referring to the two-layer working process of laminating on one side of the fabric (1) based on the solid arrows of the drawings,

First step: First, the release paper 2 is prepared.

Second step: The skin layer 3 is coated on the surface of the release paper 2.

Third Step: The state in which the skin layer 3 on the surface of the release paper 2 is formed is dried.

Fourth step: The adhesive layer 4 is formed on the fabric 1, wherein the adhesive layer 4 is formed using a mesh or dot coating roller so that the adhesive layer 4 is formed on the surface of the fabric 1. It is to be formed partially, not whole.

Fifth Step: One side surface of the fabric 1 by laminating the fabric 1 having the adhesive layer 4 and the release paper 2 having the skin layer film 3 'thereon and peeling and rolling the release paper 2 at the same time. To produce a laminated fabric (1 ') in which the skin layer film (3') is laminated.

Step 6: Inspect the finished laminating fabric 1 '.

According to the above, one side of the fabric 1 is able to manufacture a laminating fabric (1 ') consisting of the skin layer film (3').

The following describes a three-layer work process in which a skin layer film 3 'is formed between two layers of fabrics (1) (1a), which is indicated by a dotted arrow in the drawing. The sixth step will be described following the fifth step.

The sixth step: The adhesive layer 4 'is formed of a mesh type or a dot type as the adhesive layer 4' is formed on one side of the other fabric 1a, but the adhesive layer 4 is formed in the 2layer process. The adhesive layer 4 'is formed partially on the surface of the original fabric 1a by forming the adhesive layer 4' using an application roller.

7th step: The original fabric 1 in which the skin layer 3 was comprised, and the other original fabric 1a comprised only by the adhesive bond layer 4 'are combined.

Eighth Step: Inspect the finished laminating fabric 1a '.

Therefore, it is possible to manufacture a laminating fabric (1a ') consisting of a skin layer film (3') between two layers of fabric (1) (1a).

And the laminating fabric (1 ') (1a') completed after the two-layer or three-layer operation of the above through the net dryer 20 device can be efficiently recovered the reduced width of the fabric.

By manufacturing the laminating fabrics 1 'and 1a' by this method, the process is much simpler than in the prior art, and the adhesive layers 4 and 4 'are partially formed, so that they are wet in the wet state without drying the adhesive layer. As a result, it is possible to secure sufficient adhesive strength to the water-repellent treated fabric, and also by adopting a partial adhesive method, it can secure very excellent moisture permeability. By not doing so, a very soft laminating fabric can be obtained.

Hereinafter, the processing apparatus 10 for realizing the method according to the present invention as described above will be described in detail with reference to FIG. 3.

As can be seen in the drawings, the release paper preparation device 11 for supplying the release paper 2 to one side constitutes a coating device 12 for subsequently applying the skin layer 3 on the surface of the release paper (2) Configured.

After the coating apparatus 12, a dryer 13 for drying the coated skin layer 3 on the surface of the release paper 2 was installed.

On the upper end of the dryer 13, a fabric supply device 14 for supplying the fabric 1 and an adhesive coating device 15 for constructing the adhesive layer 4 on the fabric 1 are provided. The coating roller 16 for coating is configured to have a mesh or dot shape so that the adhesive is applied to the fabric 1 in a mesh or dot shape.

Below it constitutes a laminating device 17 for pressing and laminating the release paper 2 composed of the skin layer film 3 ′ and the fabric 1 composed of the adhesive layer 4, but subsequently separating the release paper 2. While forming one of the fabric (1a) is further laminated to another paper lamination device (17 ') that is used for pressing to remove the release paper (2).

Next to the fabric supply device 14 and the adhesive coating device 15 for supplying the fabric 1, another fabric supply device 14 ′ and an adhesive coating device 15 ′ are configured in a symmetrical manner. It is to be used when laminating the fabric (1a), where the application roller 16 'is also configured in a mesh or dot shape to the adhesive to the fabric (1a) is applied in a mesh or dot type.

In addition, by installing a net dryer (20) across the top and sides of the fabric supply device (14 ') and the adhesive coating device (15'), the laminating fabric whose width is shrunk under tension in the preceding process (1). Restore the width of '(1a'). The net dryer recovers the shrinkage in the width direction of the fabric by applying heat while moving the fabric on a multi-stage conveyor operating at a speed slightly slower than the entry speed of the fabrics 1 'and 1a'.

Looking at the operation of the present invention having such a configuration, first the skin layer (3) is formed on the surface of the release paper (2) while passing the release paper (2) from the release paper preparation device 11 to the coating device (12) during the two-layer operation As a result, the release paper 2 having the skin layer 3 thereon passes through the dryer 13 so that the skin layer 3 is dried to form the skin layer film 3 '.

The release paper 2 passing through the dryer 13 is supplied to the laminating device 17 and at the same time as described above, a process of forming the adhesive layer 4 on the fabric 1 is performed. The adhesive layer 4 is formed on the surface of the fabric 1 by a coating roller 16 formed in a mesh shape or a dot shape while passing through the adhesive coating device 15 while the fabric 1 is withdrawn. Is formed.

The fabric 1 is also supplied to the lamination device 17 at the same time as the release paper 2 and the release paper 2 and the fabric 1 on which the skin layer film 3 'is formed are laminated by the adhesive layer 4. After laminating in the laminating device 17, the laminating fabric 1 'is manufactured by immediately separating the release paper 2 immediately before passing through the other laminating device 17'.

Meanwhile, referring to a process of manufacturing a laminating fabric 1a 'in which two layers of fabrics 1 and 1a are laminated by the processing apparatus 10 of the present invention, in another lamination apparatus 17' which is the last step of the process The other fabric 1a is supplied in the process of separating the release paper 2, while the fabric 1a of the other fabric supply device 14 'passes through the adhesive coating device 15' and the adhesive layer ( 4 ') is configured, and the other fabric 1a is bonded to the skin layer film 3' while being supplied to the lamination device 17 'in such a state so that the laminating fabric 1a' is manufactured.

The laminating fabrics 1 'and 1a' of the release paper 2 separated are recovered from the contracted width while passing through the net dryer 20. In the case of fabrics with a lot of stretch, usually 60-inch (inch) wide fabrics are subjected to laminating processing, which is 56 inches to 57 inches, and as soon as they pass through the net dryer 20 immediately after the laminating process as in the present invention, 59 inches to Can be returned to 60 inches.

As described above, the present invention can be simplified incomparably with the conventional complicated laminating process, and the adhesive layer 4, 4 'is not placed on the skin layer 3 of the release paper 2, but the fabric 1 By applying to (1a) and applying the mesh or dot type instead of the whole surface of the fabric, there is no need for expensive facilities and time-consuming firing process, and there is no hassle of drying twice. As a result, the uncomfortable time and human waste of moving the process is eliminated.

By applying the adhesive layers 4 and 4 'in a mesh or dot form, excellent adhesion and softness and sufficient water resistance and breathability can be obtained even in the case of the fabric subjected to the water repellent treatment.

In addition, by installing the net dryer 20 immediately after the laminating process, such that the shrinkage of the fabric can be recovered as much as possible, and the present invention can be said to be a useful design that makes the laminating work very efficient.
