However, it should be understood that the following preferred embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention.
Fig. 1 is an SEM photograph showing an example of a triangular cross section of a long fiber according to a preferred embodiment of the present invention, and Fig. 2 is a photograph of a paraffin triangular cross section of a long fiber according to a preferred embodiment of the present invention.
As shown in the drawings, the nonwoven fabric having improved surface tactility according to the present invention comprises a step of melting a polypropylene resin polymer and guiding the polypropylene resin polymer toward a spinneret hole to produce a long fiber, laminating the spun long fiber on a porous continuous belt A method for producing a long-fiber polyolefin-based nonwoven fabric, comprising the steps of: forming a web of composite long-fiber; and fixing the composite long-fiber web by an embossing method partially by thermocompression bonding or by needle punching In the step of melt-spinning the molten polypropylene resin polymer, the nozzle cross-section is not a spinning process using a conventional round nozzle, but a special type of nozzle, that is, Lt; / RTI >
According to a preferred embodiment of the present invention, in the case of the triangular cross-section, it is possible to use a nose made to have a distance from the center of gravity of the triangle to the end of each corner of 0.5 to 0.9 mm, more preferably 0.55 to 0.8 mm have.
As described above, according to a preferred embodiment of the present invention, the nonwoven fabric according to the present invention applies a triangular cross-section by applying a modified shape of an existing circular nipple in melt spinning in a basic spunbond process using long-fiber polypropylene. In this process, optimization of temperature and stretching conditions for stable melt spinning finally improved soft touch performance.
In addition, the method for producing a long-spun, spunbonded nonwoven fabric of the present invention includes a step of melt-spinning the fiber material composition to form a web.
The fiber material composition as described above is put into a spinning device and melt-spinned to form extruded filaments to form a web.

The extruded filaments are solidified by cooling air injected from the chamber and laminated on a conveyor belt, stretched by the pressure of the air injected from the upper part and the air sucked from the lower part of the conveyor belt, The web is formed by stacking.
In addition, the method for producing a long-spun, spunbonded nonwoven fabric of the present invention includes a step of heat-pressing the web.
In order to impart mechanical properties and shape stability to the laminated web as described above, the web is heated to 130 to 170 DEG C in an emboss roll having a constant bonding ratio and a calender roll having a smooth surface plate roll, To form a span bond. In addition, a spun bond can be formed by fixing using a needle punching method.
Hereinafter, the present invention will be described in more detail with reference to Examples, but it goes without saying that the scope of the present invention is not limited to these Examples.
Example
And the entire polypropylene web layer had a density of 18 g / m < 2 >. The polypropylene nonwoven fabric was made to have a denier level of 1 to 2 denier at 2000 to 4000 m / min using a triangular cross section, and a hydrophilic polypropylene nonwoven fabric was hydrophilized by fixing a hydrophilic oil on the nonwoven fabric surface. At this time, an equilateral triangular bar having a distance of 0.6 mm from the edge of each corner was used. A nonwoven fabric was produced using the manufactured yarn.
Comparative Example 1
A nonwoven fabric was produced in the same manner as in the above example, except that the nonwoven fabric was produced by using a circular nip.
Comparative Example 2
A nonwoven fabric was prepared in the same manner as in the above example, except that an equilateral triangular bar having a distance of 0.4 mm from the center of gravity of the triangle to the end of each corner was used.
Comparative Example 3
The nonwoven fabric was prepared in the same manner as in the above example, except that a triangular bevel having a distance of 1.0 mm from the center of gravity of the triangle to the end of each corner was used.
Experimental Example
The polypropylene nonwoven fabrics prepared according to the above Examples and Comparative Examples were compared with each other as follows.
1. Coefficient of friction: The coefficient of friction was measured using a static friction coefficient measuring device (TOYOSEIKI AN-F). The measuring method is to contact each of the non-woven fabrics of M-type and M-type, weighing a certain weight, and displaying the angle when the upper nonwoven fabric slips down while increasing the tilt. This value is converted into TAN () value.
The smaller the value of the coefficient of friction, the more smooth the surface.
As shown in the above table, as the size of the triangular cross section increases, the surface area decreases and the friction coefficient tends to be favorable. However, it is understood that 0.5 to 0.9 mm is most preferable because it is disadvantageous to stable radiation.
Although the spunbond is described as a manufacturing technique for the release nonwoven fabric in the above embodiment, the present invention is also applied to spun lace, thermal bond, chemical bond, air through, meltblown and needle punching methods, .
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it should be understood that the same is by way of illustration and example only and is not to be taken by way of limitation in the embodiments herein. Accordingly, the invention is only defined by the scope of the claims set forth in the claims.
