Description

Bridge-fixed needle punching fabric manufacturing method and needle punching fabric manufactured by the manufacturing method {METHOD FOR MANUFACTURING NEEDLE PUNCHING FABRIC FIXED BRIDGE AND NEEDLE PUNCHING FABRIC MADE BY THIS METHOD}

The present invention relates to a needle punched fabric used as a fabric for bedding pads, mats (such as cushions), interior linings (head liners for automobile interiors, wallpaper, etc.), shoe insoles, masks, filters, etc. Preferably, needle punching is used to infiltrate nonwoven fabrics, and also to bond the fabrics to the needle punching without bonding the fabrics to prevent loosening of the fabrics. The present invention relates to a bridge fixed needle punching fabric manufacturing method capable of maintaining a state in which a functional material including activated carbon filled in a uniformly applied, and a needle punching fabric produced by the manufacturing method.

In general, the bedding pad is configured to form a cotton or non-woven fabric between the top and bottom fabric fabric, and then quilted with a quilt to maintain its shape and to impart a cushion.

On the other hand, activated carbon absorbs and removes sweat, odors and various pathogens with excellent adsorption as already known, and if iodine adsorption is enhanced during the production process, it can protect against radioactive radiation, which has become a problem recently. If the proper amount is embedded in the pad, it can be used very comfortably and also protects the user's health.

However, even though activated carbon is difficult to distribute evenly in cotton or non-woven fabric used as interior materials and evenly distributed even in cotton or non-woven fabric, activated carbon is easily discharged to the outside and scattered indoors. The loss of adsorption function is reduced as much as it is lost, and if the particles are large, it prevents the penetration of the needle during the quilting operation, so that the quilting cannot be performed properly. It could not be.

In order to solve this problem, a technique for incorporating upper and lower fabrics by needle punching has been proposed.

1 is a schematic view showing a manufacturing process of a bedding pad according to the prior art, the first and second fabrics (non-woven fabric, etc.) 1, 2 wound on the feed rollers 3, 4, respectively, and supplies activated carbon, ceramics, When functional material such as ocher is applied, the functional material 6 is applied onto the second fabric 2 on the lower side through the functional material applicator 5, and then the first and second fabrics are formed through the needle punching machine 7. The needle punched fabric 10 (see Fig. 2) is produced as an interior material by incorporating (1, 2). Needle punching fabric 10 is made of a bedding pad through the coating of the fabric fabric.

According to this conventional technique, the first and second fabrics 1 and 2 are infiltrated through the needle punching machine 7, that is, as shown in FIG. 2, by the needle of the needle punching machine 7. [Bridge in the present invention by needle in the unidirectional case]

In needle punching the first and second fabrics (1,2), the second fabric (2) is connected to the first fabric (1) while referring to the fiber strands of the first fabric (1) caught on the needle. To penetrate the first and second fabrics (1,2), but the bridge 11 is only inserted through the second fabric (2), so that it is in the process of being manufactured, in use and washed. There is a problem of missing from the second fabric 2 at the time. As a result, an invasion fracture state in which the first and second fabrics 1 and 2 are separated from each other occurs.

In addition, the disappearance of the bridge 11, which serves as a function of maintaining the position of the functional material 6 between the fabrics, causes the functional material 6 not to maintain a uniform state and is biased to one side. Needle punching fabric 10 is applied to the use of consumables such as beddings, mats, masks, insoles, etc., giving the user a rugged feeling, which has a problem of inferior merchandise.

On the other hand, there is also a method of bonding the fabrics impregnated by needle punching with heat and adhesive by using an adhesive during needle punching, but since this is not a method of fixing only the bridge, the amount of adhesive is increased and the process is complicated. There is a problem in that the bridge portion in the broken or broken to eliminate the fixing of the fabrics by needle punching, the adhesive also closes the pores of the functional material such as activated carbon, the functional material can not function at all.

Needle punching is, of course, not only used in the manufacture of bedding pads, but also in the manufacture of fabrics such as interior liners (car headliners, wallpaper, etc.), thermal mat finishes, shoe insoles, masks and filters. That is, the above-mentioned problem occurs when punching all needles other than the bedding pad.

As shown in Figures 3 and 4, the method for manufacturing a bridge fixed needle punching fabric according to the present invention, the first step of supplying the first and second fabrics (1,2)-the functional material (2) on the second fabric (2) 6) The second process of applying (activated carbon, etc.)-The third process of incorporating the first and second fabrics (1,2) by needle punching and fixing the functional material (6) to hold the position without moving-needle It consists of a fourth step of fixing the end of the bridge (protrusion through other fabric) made during punching.

1. Supply of 1st and 2nd fabric.

The first and second fabrics 1 and 2 include all fabrics to which the present invention can be applied, such as nonwoven fabrics, including two materials joined by needle punching, that is, needle punching in which the end of the bridge is fixed by the present invention. The fabric is also included), and is wound around the feed rollers 3 and 4. Positions and the like of the feed rollers 3 and 4 are not limited to those shown in the drawings.

2. Application of functional materials.

Functional materials include activated carbon or granular ceramics, granular ocher, fine pores and functional ingredients (fragrances, etc.)

At least one selected from the impregnated activated carbon is used, and when two or more are mixed, there is no large change according to each mixing ratio, so the specific mixing ratio is not limited to a numerical value.

Alternatively, the functional material may be a particulate material having a bactericidal component and an antibacterial component.

The functional material applicator 5 is to apply the functional material 6 (which refers to everything that emits a human beneficial component such as activated carbon) between the first and second fabrics 1 and 2 (evenly as a whole), Since it is a ready-made product widely used in the field to which the present invention is applied, a detailed configuration will be omitted.

The functional material applicator 5 is configured to apply the functional material 6 over the second fabric 2, which is disposed relatively lower.

The functional material application process is not necessarily applied in the present invention, that is, the process is omitted in the needle punched fabric that does not use the functional material (6).

3. First and second fabric invasion.

The first and second fabrics 1 and 2 are immersed in the process of passing through the needle punching machine 7, and more specifically, the plurality of needles of the needle punching machine 7 are arranged on the second fabric 1 above the second fabric. The fabric is lowered toward the second fabric 2 so as to perforate the fabric 2, and in this process, a part of the first fabric 1 penetrates the second fabric 2 so that the first and second fabrics 1 and 2 are removed. The bridge 11 to be seized is made, and the edge part of the bridge 11 protrudes to the outer side of the 2nd raw material 2 (it does not protrude, but can be fixed to the 2nd raw material 2).

The present invention is capable of both unidirectional / bidirectional needle punching. That is, a plurality of needles of the needle punching machine 7 is disposed on the first fabric 1 so that the bridge 11 penetrates the second fabric 2 and is fixed to the second fabric 2 [second fabric ( The bridge of 2) penetrates the first fabric 1 and is fixed to the first fabric 1], as described above, by forming the bridge 11 in the first fabric 1 to the second fabric 2 After fixing the unidirectional needle punching, both directions of bidirectional needle punching by two steps of forming a bridge in the second fabric 2 and fixing it to the first fabric 1 are possible.

Since the plurality of bridges 11 are configured to infiltrate the first and second fabrics 1 and 2, when the functional material 6 is applied, a certain amount of the functional material 6 is trapped between the bridges 11. Thus, the functional materials 6 are held out of the bridge 11 by the surrounding bridges 11 and remain in place, i.e., maintain a uniform coating state.

4. Secure the bridge.

In this process, the bridge 11 fixed to the second fabric 2 only by the puncturing of the needle is fixed by the physical / chemical method so that the first and second fabrics 1 and 2 remain in an infiltrated state, and the functional material When (6) is applied, the functional materials 6 are held in position, and the method of fixing the bridge 11 will be described in detail.

end. Fixed bridge by flame (heat).

The first and second fabrics 1 and 2, which are infiltrated by the needle punching machine 7, are transferred to one side, and install flames in the transfer path. The flame machine is installed so that the flame nozzle sprays the flame at the bottom of the second fabric 2 (the portion through which the bridge 11 penetrates), and the end of the bridge 11 which penetrates the second fabric 2 by the flame. To be supported. According to the above process, as shown in FIG. 5, the fixing tip 11a by a flame is made in the edge part of the bridge 11. As shown in FIG.

The fixing tip 11a is made by the deformation of the bridge 11, and is made by the flame at a temperature lower than the melting point (or the carbonization point) of the first and second fabrics 1 and 2. The bridge 11 is a part of the first fabric 1 but is a very small structure (silk, etc.) compared to the size of the first fabric 1, so that the bridge 11 may be deformed even at a temperature lower than the melting point of the first fabric 1. . If the flame is sprayed at a temperature higher than the melting point of the first and second fabrics (1,2), the first and second fabrics (1,2) are melted and a product cannot be made. In addition, the flame time is also related to the speed at which the first and second fabrics 1 are transported, and the direct flame time can be variously adjusted, such as 1 second or less, 1 second to 3 seconds, and the first and second fabrics 1, 2 ), There is no reason to limit to a specific numerical value because it depends on the material of the material, the feed speed of the first and second fabrics (1, 2), the flame temperature and the like.

The temperature of the flame and heat for fixing the bridge 11 depends on the characteristics (melting point) of the fabric (PE, PP, etc.), that is, about 10% lower than the melting point of the fabric (melting point of polyethylene 180-200 ° C.) to melting point. Applying a low temperature heat is the end of the bridge 11 is burned or thermally deformed to create a fixing tip (11a).

The formation of the bridge 11 depends on the temperature of the flame and heat and the conveying speed of the fabric.

The fixing tip 11a is larger than the hole of the second fabric 2 through which the bridge 11 is drilled or joined together with the second fabric 2 (the second fabric 2 by thermal deformation of the bridge 11. It may be bonded together to the bottom of the)] to maintain the engagement state of the first and second fabric (1,2).

In the bridge fixing process by the flame (heat), the pressing process may be performed together to increase the fixing force of the fixing tip 11a of the bridge 11. For example, as a subsequent step of the flame process, pressure rollers are installed on the upper and lower portions of the first and second fabrics 1 and 2, respectively, and the fixing tip 11a is pressed by pressing the pressure roller. The cross-sectional area may be increased and the fixing tip 11a may be bonded to the second fabric 2.

I. Fixing the bridge by the application of adhesive.

As shown in FIG. 6, after the first and second fabrics 1 and 2 are infiltrated by the bridge 11 through a needle punching process, an adhesive is applied to an end portion of the bridge 11 protruding from the second fabric 2. By forming the adhesive tip 11b, the end of the bridge 11 and the second far end 2 are bonded to each other.

The method of applying the adhesive may be made by, for example, an adhesive applicator and an adhesive roller. That is, the adhesive applicator applies a liquid (gel-like) adhesive on the surface of the adhesive roller, and the adhesive roller attaches the adhesive on the surface of the end of the second fabric 2 and the bridge 11. (11b) is formed. At this time, the pressure roller may be provided next to the adhesive roller for curing and pressing the adhesive tip 11, or may be provided with a pressure roller on the opposite side of the adhesive roller.

In the bonding process, it is preferable to set the temperature of the adhesion chamber to the curing temperature for curing the adhesive.

All. Fixing the bridge by attaching the adhesive sheet.

The end of the bridge 11 is fixed to the bottom of the second fabric 2 by attaching the adhesive sheet 11c to one surface of the second fabric 2 on which the edge of the bridge 11 protrudes.

The adhesive sheet 11c has a release paper 11d attached to the adhesive surface and can be used in a roll form. After removing the release paper 11d, the adhesive sheet 11c is attached to the bottom surface of the second fabric 2. The bridge 11 is fixed to the second far end 2 by pressing the adhesive sheet 11c through the pressure roller 11e.

Hereinafter, an embodiment to which the needle fabric according to the present invention is applied will be described.

≪ Example 1 >

As shown in Figures 8 and 9, the bedding pad to which the bridge-type needle punching fabric according to the present invention is applied is made of a needle punching fabric 10, a finishing material, for example, upper and lower fabric fabrics 20 and 30.

Needle punching fabric 10 is used as the interior material of bedding, is fixed through the quilted 40 between the top and bottom fabric fabric (20, 30), the edge of the top and bottom fabric fabric (20, 30) is finished by sewing Treated to protect the needle punched fabric 10.

That is, the shape retention by the quilted 40 and the cushion by the first and second fabrics (1,2), which are non-woven fabrics, satisfy the basic functions as bedding pads, and the activated carbon is evenly distributed throughout, so that the moisture absorbs sweat and the like with excellent adsorption properties. It will be able to absorb and remove the smell and various pathogens, so that it can be used more comfortably and also protect the health of the user.

In the present embodiment, the first and second fabrics 1 and 2 of the needle punching fabric 10 are each weighing about 200 to 400 g per 1 m 2, and as a functional material, the activated carbon is 1.2 to 3 mm in size and the weight per 1 m 2. It is about 300-400g.

At this time, the first and second fabrics (1 and 2), each of which is a nonwoven fabric, have a gap between the fiber tissues when the weight is less than 200 g per 1㎡, which may cause leakage of activated carbon, as well as cushioning due to the activated carbon of 1.2 to 3 mm size. If the weight is more than 400g per 1㎡, the thickness is too thick needle punching can not be made properly, as well as the thickness of the product becomes thicker than necessary, it is desirable to keep the given amount of use.

In addition, if the activated carbon is less than 1.2 mm in size, there is a risk of spillage between the fiber tissues of the first and second fabrics (1,2). There is a concern that the activated carbon may also interfere with the needle penetration or cause the needle to break even when the activated carbon is distributed in an amount of 400 g or more per m 2.
