Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-woven fabric manufacturing apparatus and a manufacturing method,

The present invention relates to a nonwoven fabric manufacturing apparatus and a manufacturing method thereof, and more particularly, to a nonwoven fabric manufacturing apparatus and a manufacturing method which are capable of mass production of nonwoven fabrics having no directionality and excellent strength so that they can be widely used in various industrial fields.

The nonwoven fabric is made of felt in the shape of a felt, which is arranged in parallel or in an indefinite direction without being subjected to a woven process and bonded with a synthetic resin adhesive. As raw fibers, cotton / viscose rayon was mainly used, And synthetic fibers such as nylon were also used.

There are immersion (immersion) and dry (dry) processes for nonwoven fabrics. Sewing is also called paper-making, and it is similar to paper in that the fibers are wetted in a synthetic resin adhesive bottle, dried and heat-treated. The dry type is made by blowing synthetic resin into a thin cotton-like fiber and drying it by applying heat.

The production technology of nonwoven fabric has been developed rapidly in the US since about 1950, and it is widely used for various industrial applications because there is no directional nature of the fibers because the fibers are intertwined and the cut edge is not loosened.

The nonwoven fabric has very different properties depending on the type of raw materials used, the method of producing and binding the web, the type of the adhesive, and the like. Accordingly, it is difficult to describe the properties and characteristics of the nonwoven fabric. However, typical properties include filtration properties, warmth, moldability, water absorbency, insulation, and dielectric properties.

However, when the nonwoven fabric is used in the first place because the difference in the characteristics of the products is great, the nonwoven fabric can be easily selected and developed for the purpose of using the nonwoven fabric.

The general advantage of nonwoven fabric is that it can be manufactured in the form of paper and felt with various appearance, ② can change the thickness freely, ③ does not wrinkle, and ④ most of the synthetic polymer used fiber and adhesive is wrinkle- , The shape stability is great, (5) the end portion is not loosened like a fabric, (6) an altar can be freely rotated in any direction, (7) the range of strength is wide, (8) the elastic property is good, . It may show absorbency, insulation, conductivity and so on.

On the other hand, the general disadvantages of the nonwoven fabric are that it is difficult for the jacket to have a small drape property, (2) it has a directionality and causes damage in a specific direction, and (3) the pilling property is poor.

Generally, as a method of producing nonwoven fabric, short fibers are opened, stored in a reserve tank, and then supplied to a card reader. At this time, the card reader opens the supplied short fibers and arranges them in a predetermined direction to form a thin paper web .

The web made by the card machine is conveyed by the conveying means, the web is laminated by the lamination means, and the laminated web is needle-punched to manufacture a nonwoven fabric, or the laminated web is preheated and fused to form a web Thereby producing a nonwoven fabric.

Patent Registration No. 10-0655181 Japanese Patent Application Laid-Open No. 10-1150820

In the conventional nonwoven fabric manufacturing method as described above, staple fibers are opened by using a card machine and are laid out in a predetermined direction, so that a web made of a thin paper is laminated using a laminating means. The final finished nonwoven fabric has a directionality.

The directionality of the nonwoven fabric may cause the nonwoven fabric to easily stretch or deteriorate in tear strength due to the direction in which the web is formed. If the nonwoven fabric has a directionality that causes easy damage or tearing damage, the range of use of the nonwoven fabric is greatly restricted. In particular, in the case of a nonwoven fabric used for construction purposes for insulation, soundproofing, However, since conventional nonwoven fabrics have a disadvantage of being easily torn in the grain direction, when nonwoven fabrics are used for construction, the nonwoven fabrics are frequently used in a stacked manner in various directions, There is a problem in that the cost of materials is increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the apparatus and method for manufacturing a nonwoven fabric according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a plan view of a nonwoven fabric manufacturing apparatus according to the present invention. The nonwoven fabric manufacturing apparatus includes a first card unit 102 (see FIG. 1) for forming a first paper web A )Wow;

An X-axis conveyor 101 for conveying the web formed by the first card machine 102 in the X-axis direction;

A second card maker 202 installed in a direction perpendicular to the X-axis conveyor 101 to form short web-shaped second webs B in a staggered arrangement of short fibers;

A Y-axis conveyor 201 for supplying a second web B formed by the second card machine 202 to the X-axis conveyor 101 in a direction perpendicular to the X-axis conveyor 101;

A Y-axis molding machine for forming a second web B supplied from the Y-axis conveyor 201 in a staggered manner in the Y-axis direction on the first web A being conveyed by the X-axis conveyor 101 203;

The web conveyed in the X-axis conveyor 101 in a state where the second web B is laminated on the first web A is formed in a staggered manner in the X-axis direction on the third conveyor 301, A molding machine 103;

And a needle puncher (401) for forming irregular tangles in the web structure fed from the third conveyor (301).

The apparatus may further include a compression roller 501 for compressing the web to a predetermined thickness for compressing the web to a predetermined thickness before needle punching the webs cross-laminated in the XY axis direction conveyed from the third conveyor 301.

In addition, in order to make the web structure having the needle punching completed more solidly, a water-soluble paste is applied to a sheet-shaped web by a jetting device 601 in the back of the needle punching device 401, And a heating roller 701 for pressing to be stabilized.

The carding machine (M / C) is a device for making short webs supplied from a hopper feeder to bind the short webs to each other while passing them through different rollers of different webs to form a web, Is formed into a sheet-like shape by forming webs with a certain width and thickness.

The thickness of the sheet-like web is increased by allowing the sheet-shaped web formed in the card unit to be fed in the vertical direction while being shaken at a constant amplitude and being laminated in multiple layers by the molding machine (Wed Cross Layer).

When the web passes through the molding machine as described above, the web is greatly increased in thickness by the laminated web. Therefore, the web is passed through a press roller 501 (cross roller) to compress the web to 5 to 30% Compress.

The webs passed through the compression rollers 501 are punched by repeatedly up and down movements using various kinds of needles on the surface or back side of the laminated fiber layers to form a fiber layer having a uniform thickness and fiber density (Punching M / C), which causes the web punching machine 401 to pile up.

On the other hand, the web routed through the compression rollers 501 is punched by repeatedly up and down movements using various kinds of needles on the front surface or back surface of the laminated fibrous layer, thereby physically entangling the fibrous layers with a constant thickness and fiber density (Punching M / C) for forming the web punching machine (401) (Punching M / C).

The sheet-shaped web passed through the needle punching device 401 is coated with a water-soluble paste by applying a stitch bond method, and the product is stabilized by a heat roller for pressing, thereby making it possible to manufacture a nonwoven fabric having enhanced rigidity.

The nonwoven fabric manufacturing method using the nonwoven fabric manufacturing apparatus according to the present invention as described above will now be described. A first card A is formed by laminating staple fibers in a predetermined direction using a first card machine 102, And transporting them in the X-axis direction;

Forming a second web (B) of a thin paper shape by arranging the short fibers in a predetermined direction using the second card machine (202), and transferring the second web (B) in the Y axis direction;

Stacking the second web (B) conveyed in the Y axis direction in a staggered manner in the Y axis direction on the first web (A) conveyed in the X axis direction by using a laminating means;

The first web A is stacked on top of the second web B in a staggered manner in the Y-axis direction so that the first web A is piled up in a zigzag manner in the X- And the second web (B) are crossed with each other in the XY axis direction;

And forming the irregular tangles in the web structure by needle-punching the first web (A) and the second web (B) which are stacked so as to cross each other in the XY axis direction.

That is, the nonwoven fabric manufacturing apparatus and the nonwoven fabric manufacturing method according to the present invention have a structure in which the staple fibers constituting the web are repeatedly stacked alternately in the X-axis direction and the Y-direction, while being irregularly tangled And therefore, it has a non-directional characteristic.

Therefore, the nonwoven fabric has advantages inherent to the nonwoven fabric, and one of the important disadvantages of the nonwoven fabric is improved directionality and the emphasis reduction thereof, thereby enhancing the strength of the nonwoven fabric. As a result, not only the construction materials requiring strong strength for the purpose of heat insulation, soundproofing, , It is possible to manufacture nonwoven fabrics having versatility widely applicable in various industrial fields.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
