Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hygiene article using a hydrophobic surface sheet,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary article using a topsheet made of a hydrophobic material and an apparatus for manufacturing the sanitary article.

While there are many disposable personal hygiene articles (e.g., sanitary napkins, diapers) that collect body fluids, the tendency to leak from the surface before the liquid absorption capacity is fully utilized is a continuing challenge facing many manufacturers. In addition, some fluids, such as diapers and sanitary napkins, make it especially problematic to obtain good suction and distribution performance to accommodate the viscoelastic properties of menstrual discharge and dilute BM (feces).

In particular, the relatively high viscosity and / or elasticity of such fluids tends to interfere with the absorption and distribution of fluid within the absorbent article. In other cases, the suction performance of the absorbent article may be interrupted when the components of the menses discharge the channels between the particles or fibers contained in the absorbent article. This phenomenon is often referred to as fouling.

Thus, in the past, attempts have been made to improve the effect of contamination through modification of the viscoelastic property of the fluid itself. However, since complete absorption can not be achieved, the liquid remains on the surface contacting the skin, There is a problem.

In addition to the leakage problem, conventional disposable personal hygiene products also have hygiene problems that directly affect the user. Often, body fluids come in direct contact with the user, which can give an unpleasant and unclean feel, and has problems that cause skin disorders as they come into direct contact with the skin.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of a sanitary article using a hydrophobic surface sheet according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a sanitary article using a hydrophobic surface sheet according to the present invention, FIG. 2 is a plan view of FIG. 1, FIG.

1 to 4, a sanitary article using a hydrophobic surface sheet according to the present invention comprises a top sheet 100 of a hydrophobic material forming a contact surface with the skin, And a lower sheet 200 of a hygroscopic material which absorbs urine, blood, stool, body fluids secretion).

The surface sheet 100 is made of high density fibers (for example, nonwoven fabric of 1.0 dtex to 3.0 dtex) and is made of a hydrophilic or hydrophobic high denier For example, 5 to 6 denier).

Here, the surface sheet 100 is preferably a sheet applied with 1.2 to 1.7 dtex (40 to 50%) or a sheet with 1.7 dtex (50%) and 2.2 dtex (50%) bonded.

That is, the topsheet 100 is made of a hydrophobic material that is not permeable to fluids, and is made of a material having high denier so as not to give a stimulus as it comes into contact with the skin.

In addition, the topsheet 100 includes a plurality of convex patterns 110, a perforation hole 120, and a joint point 130 to minimize fluid permeation and skin irritation.

The convex pattern 110 is formed as a conical protrusion protruding upward from the upper surface of the topsheet 100, and an inner space is formed as an empty space to form an air layer as shown in FIGS.

In addition, since the convex pattern 110 is formed as a protrusion upward from the upper surface, the contact surface with the skin can be minimized so that troubles such as skin rashes can be prevented. Further, the inner air layer can provide a cushioning feeling.

The perforation hole 120 transmits the fluid introduced into the topsheet 100 to the bottom sheet 200 at the bottom. Here, the perforation holes 120 may be formed between the convex patterns 110 as a plurality of holes. That is, the perforation hole 120 discharges the fluid, which is not absorbed by the topsheet 10090 made of a hydrophobic material, to the lower sheet 200 of the absorbent material.

Here, referring to FIG. 2 to FIG. 4, the perforation holes 120 are spaced apart from each other around the convex pattern 110 to form a plurality of holes. For example, the perforation holes 121, 122, 123, and 124 may be spaced about the convex pattern 110, but may be formed in the same number as the joint point 130 described later.

Alternatively, the diameter of the perforation holes 120, 121, 122, 123, and 124 may be selected to have an area ratio of 15 to 40% of the total area of the topsheet 100.

As shown in FIG. 2, the topsheet 100 may have a stepped surface that is lower than the surface of the topsheet 100 between the patterns 110 that are adjacent to each other and form a rhombus or a quadrangle, And a concave portion 140 for collecting the fluid.

The concave portion 140 can impart directionality and speed so that the fluid discharged to the topsheet 100 can be collected. In addition, the perforation hole 120 is preferably formed in the concave portion 140.

That is, in the topsheet 100 of the present invention, since the recesses 140 formed with the perforation holes 120 are formed between the convex patterns 110, the fluid is gathered between the convex patterns 110, 200 to prevent the fluid from remaining in the topsheet 100 or from flowing backward from the bottomsheet 200.

In addition, the joint points 130 are formed such that a plurality of points are spaced apart from each other between the perforation holes 120 around the convex pattern 110. Or the joint points 130,131 and 132 may be positioned between the convex patterns 110 aligned in a diagonal direction where the concave portions 140 are not formed, for example.

Preferably, the joining point 130 may be formed in an area of 3 to 10% or less (more preferably 3 to 4%) in the area of the entire surface sheet.

More preferably, the joining point 130 is formed by press-molding so as to have a thickness thinner than other regions for ultrasonic welding, which will be described later.

The lower sheet 200 is made of an absorbent material and adhered to the lower surface of the topsheet 100 by adhesion (for example, ultrasonic welding). For example, the lower sheet 200 may be made of fibers having an eccentricity of 5 denier x 51 mm or 6 denier x 51 mm, which have excellent liquid permeability and strong restoring force. Therefore, the lower sheet 200 is adhered at the lower portion of the topsheet 100 to absorb the fluid introduced through the perforation hole 120.

In order to confirm whether the object of the present invention has been attained through the comparison between the structure of the present invention and the conventional art, applicants have confirmed the absorption rate and the prevention of backflow through a total of four samples, Results were obtained.

As a hydrophilic top sheet 100, a perforation hole 120 was formed at a ratio of 17% of the total surface area. Sample 2 was a hydrophilic top sheet 100 having a ratio of 17% The perforation hole 120 was formed at a ratio of 20.25% of the total area of the hydrophilic top sheet 100 as the sample 3, and the hydrophilic top sheet 100 was 20.25% of the total area as the hydrophobic top sheet 100 The perforation hole 120 is formed in the base material 100, and the technique of the present invention is applied. Here, the sample 4 is a technique to which the present invention is applied, and a plurality of perforation holes 120 are formed on a flat surface instead of the concave portion 140.

The upper samples 1 to 4 were bonded with the lower sheet 200 of an absorbent material.

A total of six samples were prepared and the absorption rate and the retention rate (Rewet) of each sample were measured.

In general, the management range of sanitary ware has a standard of 0.7 / sec of absorption rate and 0.3 / g of reverse flow rate. Therefore, the comparison of each sample is explained together with whether or not the standard value of the above management range is satisfied.

As a result of the measurement, the sample 1 had the perforation hole 120 formed on the hydrophobic surface, but the perforation hole 120 was not provided and the perforation hole 120 was narrower than the entire area, 120, the fluid is delayed from being discharged to the lower sheet 200, and a reverse flow phenomenon occurs. That is, the absorption rate could not satisfy the reference value.

As the hydrophilic surface sheet 100 was applied to Sample 2, the absorption rate satisfied the reference value, but exceeded the reference value of the backflow rate. That is, as the hydrophilic surface sheet 100 was applied to the sample 2, the fluid was retained in the topsheet 100 and the backflow rate was high.

In the sample 3, the perforation hole 120 was formed in the hydrophilic surface sheet 100 in the same manner as in the present invention, and thus the absorption rate satisfied the reference value, but the backflow rate was higher than the reference value as the hydrophilic surface sheet was made of the hydrophilic surface sheet.

Sample 4 was a product to which the present invention was applied, and the absorption rate was lower than that of Sample 2 and Sample 3 due to the hydrophilic surface sheet 100, but the criterion for the backflow rate was good. That is, in the sample 4, the liquid phase remained and no backwash occurred in the topsheet 100.

In addition, according to the present invention, when the concave portion 140 is provided as the upper sample 4 is manufactured without adding the concave portion, it is determined that the absorption rate of the fluid can be improved.

In conclusion, the present invention can prevent irritation such as skin rashes and troubles of a wearer when applied to sanitary articles such as diapers and sanitary napkins, for example, to provide smooth running smoothness, cleanliness and cushioning feeling.

The sanitary article using the hydrophobic surface sheet according to the present invention includes the above-described structure, and the manufacturing apparatus and the manufacturing method will be described below.

5 is a schematic view illustrating an apparatus for manufacturing a sanitary article using a hydrophobic surface sheet according to the present invention.

5, an apparatus for manufacturing a sanitary article using a topsheet 100 of a hydrophobic material according to the present invention includes a fin roller 310 for perforating a hole in a topsheet 100, A pattern roller 320 for forming the pattern 110, a lapping roller 330 for lapping the topsheet 100 and the bottom sheet 200, a first moving roller 410 for moving the topsheet 100, A second moving roller 420 for guiding the lower sheet 200 and an ultrasonic welder 500 for ultrasonic welding the top sheet 100 and the lower sheet 200.

The pin roller 310 is rotated by the power transmitted from a driving device (not shown) to transfer the topsheet 100 guided from the first moving roller 410 to the pattern roller 320 side. Here, the pin roller 310 includes a pin roller negative concave groove 311 that is downwardly directed to the outer surface 313 and a protruding pin 312 that is upwardly projected from the outer surface 313.

The pin roller negative concave groove 311 is made of a groove which is inwardly directed from the outer surface 313 so as to be engaged with the pattern roller 320,

The projecting pin 312 is protruded from the outer surface 313 between the pin roller negative depressed grooves 311 to press the surface sheet moved between them by cooperation with the pattern roller 320 to perforate the perforation hole 120 .

The pattern roller 320 is rotated while being engaged with the pin roller 310 and the lapping roller 330 to simultaneously perform the process of forming the perforation hole 120 and the convex pattern 110 in the topsheet 100. For this purpose, the pattern roller 320 has protruded relief grooves 322 and inwardly oriented pattern roller engraved grooves 321, respectively.

The relief grooves 322 protrude from the outer surface of the pattern roller 320 to form the pattern 110 on the topsheet 100 while engaging with the pin roller intaglio grooves 311 and the later-described lamination roller engraved grooves 331, respectively.

The pattern roller engraved groove 321 serves to support the topsheet 100 and to support the projecting pins of the pin roller 310 to perforate the topsheet 100. For example, the topsheet 100 delivered by the pin roller 310 is moved in a flatly pulled state at the entrance side of the pattern roller engraved groove 321. At this time, when the pin roller 310 is rotated while being engaged with the pin roller 310, the projecting pin is engaged with the pattern roller engraved groove 321 to form the perforation hole 120 in the topsheet 100.

The surface sheet 100 is pressed against the pattern roller 320 and the pinch roller 310 while being in contact with the relief groove 322 and the depressed groove of the pattern roller 320 by the engagement between the pattern roller 320 and the pin roller 310, (330) is transferred to the lapping roller (330) through the process of engaging.

The lapping roller 330 includes a plurality of inwardly facing multiple lapping roller engaging grooves 331 and a point protrusion 332a which is formed by protruding protrusions and forms a lapping point 130. [

The concave roller concave grooves 331 are formed so as to be spaced apart from each other inward from the outer surface and are engaged with the relief grooves 322 of the pattern roller 320 to receive the surface sheet 100.

At this time, it is preferable that the width 11 of the pattern roller engraved groove 321 is formed to be narrower than the length 12 of the outer surface formed between the engraved roller engraved grooves 331. The difference in length between the pattern roller engraved groove 321 and the engraved roller engraved groove 331 enables the formation of a joint point by the point protrusion 332a.

That is, the point protrusion 332a is formed at a position coinciding with the central portion of the pattern roller engraved groove 321. [ The outer surface of the lapping roller 330 formed at the center of the point protrusion 332a of the lapping roller 330 and the outer surfaces of both sides of the pattern roller engraved groove 321 are brought into contact with each other so that the pressure is applied to the surface sheet 100. The topsheet 100 is formed into the shape of the point protrusion 332a by the pressure resulting from the engagement between the pattern roller 320 and the lapping roller 330. [

The joint point 130 is formed in a direction opposite to the convex pattern 110 as the convex pattern 110 is in contact with the joint roller negative concave groove 331.

That is, the convex pattern 110 is formed to protrude upward from the upper surface of the topsheet 100, but the joining point 130 is formed in the opposite direction to minimize adhesion area with the lower sheet 200 and increase adhesion have.

Therefore, the lapping roller 330 rotates the topsheet 100 in a squeezed state on the outer surface, and lips the bottomsheet 200 guided by the second moving rollers 410 and 420.

The ultrasonic welder 500 ultrasonically fuses the top sheet 100 and the bottom sheet 200 joined together by the lapping roller 330. Here, the ultrasonic welder 500 is welded to the joint point 130 while being contacted with the ultrasonic wave electrode.

The ultrasonic welder 500 strikes the joint point 130 formed by the engagement between the point protrusion 332a of the joint roller 330 and the pattern roller 320 to ultrasonic weld the joint point. That is, in the present invention, by setting the fusing position of the ultrasonic fusing device 500 in advance and pressing the topsheet 100 in order to increase the bonding force at the time of fusing, the joining point 130 is formed to increase the bonding force at the time of ultrasonic welding have.

In addition, the formation of such a joint point 130 can minimize the film film generated in the joint area due to the ultrasonic energy.

That is, as the surface area of the top sheet 100 and the bottom sheet 200 is increased, the area of the film is increased and the absorbency of the lower sheet 200 may be lowered.

Accordingly, in order to minimize the film thickness of the film by the ultrasonic waves and to increase the bonding force, the present invention preforms a joint point 130 on the topsheet 100 by press molding. Therefore, the present invention can increase both the bonding force and absorbing force between the lower sheet 200 and the topsheet 100.

The present invention includes a method of manufacturing a sanitary article using the topsheet 100 made of a hydrophobic material through the above-described structure, which will be described with reference to FIG.

6 is a flowchart showing a method of manufacturing a sanitary article using the topsheet 100 of a hydrophobic material according to the present invention.

Referring to FIG. 6, the present invention includes a step S100 of drilling a perforation hole 120 in a topsheet 100, a step S200 of forming a topsheet 100 with a convex pattern 110, (S300) of forming a joint point (130) on the top sheet (100) and the bottom sheet (200), and S400 of laminating and ultrasonic welding the top sheet (100) and the bottom sheet (200).

In step S100, a plurality of perforation holes 120 are formed in the topsheet 100 by cooperating with the fin roller 310 and the pattern roller 320. The topsheet 100 and the bottomsheet 200 are drawn from different winding rollers. At this time, the topsheet 100 and the bottom sheet 200 are respectively moved by the rotation of the first moving rollers 410 and 420 and the second moving rollers 410 and 420, respectively. The first moving rollers 410 and 420 and the second moving rollers 410 and 420 are formed as a single or a plurality of rollers and move the topsheet 100 and the bottomsheet 200 respectively through forward or reverse rotation, .

The perforation hole 120 is formed by pressing the topsheet 100 in accordance with the engagement of the fin roller 310 and the pattern roller 320 while being moved in a form trapped on the outer surface of the fin roller 310. [ That is, the projecting pin of the pin roller 310 penetrates the topsheet 100 through the perforation hole 120 in the process of engaging the pattern roller engraved groove 321.

Here, the projecting pin may have a conical shape whose diameter increases as it goes downward from the tip end, and the projecting pins may be formed into a single group. For example, the projecting pins may be formed of four spaced apart to form four perforation holes 120 in the concave portion 140 of the topsheet 100.

More preferably, the projecting pin is formed so that the diameter of the projecting pin decreases as the diameter decreases from the tip end, so that the recessed portion 140 is formed by compressing another unperforated region.

In step S200, the pattern rollers 320 press the topsheet 100 through the engagement of the lapping rollers 330 to form the convex patterns 110 and transfer them to the lapping rollers. The topsheet 100 is transferred to the lapping roller 330 in tight contact with the pattern roller negative depression grooves 321 to the depressed depression grooves 322 by the compression between the pattern rollers 320 and the fin rollers 310.

Therefore, the convex pattern 110 is compression-molded in the process of pressing the pattern roller 320 and the fin roller 310 and transferring the pattern roller 320 to the lapping roller 330.

Step S300 is a step of forming the joint point 130 in the topsheet 100. The topsheet 100 is in contact with the pattern roller negative concave grooves 321 to the concave grooves 322 in the process of being transferred from the pattern rollers 320 to the lint roller 330, So as to be brought into close contact with the outer surface. At this time, a point projection 332a protruding from the outer surface of the lapping roller is positioned on the center side of the pattern roller negative-pitch groove 321, and an outer surface of the pattern roller negative-pitch groove 321 is in close contact with the outer surface of the lapping roller 330. Therefore, the top sheet 100 is pressed onto the point protrusion 332a and the top sheet 100 is formed with the binding point 130. [

Here, it is preferable that a plurality of spacing points 130 spaced from each other around the convex pattern 110 are formed, and 5% or less (for example, 3.5%) of the total area is formed as a ratio.

In step S400, the topsheet 100 and the bottomsheet 200 are joined together by ultrasonic welding after laminating. When the top sheet 100 and the bottom sheet 200 drawn out from the lapping roller 330 are joined together, the ultrasonic welder 500 contacts the bottom sheet 200 and applies ultrasonic waves to bond both sheets. At this time, since the joint point 130 is press-formed in the direction opposite to the convex pattern 110, the joint point 130 is thinner than the thickness of the other region, so ultrasonic welding is easier and its bonding force can be increased.

Therefore, in the sanitary article using the topsheet 100 having the hydrophobic material according to the present invention, a plurality of convex patterns 110 are formed to be spaced apart from each other on the surface of the topsheet 100, The joint point 130 and the perforation hole 120 are formed. Here, the perforation hole 120 is formed in the concave portion 140 composed of the recessed depressed regions between the convex patterns 110.

The fluid that has flowed into the topsheet 100 is gathered in the recess 140 between the convex patterns 110 and absorbed into the bottom sheet 200 through the perforation hole 120. Here, since the surface sheet 100 is made of a hydrophobic material, the fluid can be completely flowed through the perforation hole 120 without being absorbed.

Therefore, as the fluid does not remain on the topsheet 100 directly contacting the skin, the wearer can maintain comfort and cleanliness instead of discomfort due to, for example, urine, stool, blood.

Further, since the convex pattern 110 is provided, the contact area with the skin can be minimized, and the cushion feeling due to the air layer inside can be sensed.
