Description

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an absorbent pad, and more particularly, to an absorbent pad having less friction with the skin and having improved absorbency, ventilation and deodorizing function.

In general, the absorbent pad of pulp material rubs against the skin, causing skin damage due to skin rash, bacterial propagation and contamination, and can not receive a soft feeling when worn without using natural fibers, and an unpleasant smell occurs in severe cases (Japanese Patent Publication No. 1994-072328)

In addition, since it is added with a chemical component, it is not only harmful to human body but also has a disadvantage that it can cause various diseases such as dermatitis and allergy due to poor ventilation.

Japanese Patent Publication No. 1994-072328 (September 14, 1994)

In order to solve the above-mentioned problems, it is an object of the present invention to provide an absorbent pad having less friction with the skin.

It is also an object of the present invention to provide an absorbent pad having an improved water absorption, ventilation and deodorizing function.

The present invention relates to an absorbent pad comprising a relatively thin first cotton yarn than the modern wool and modern wool and comprising a composite woven fabric layer having a relatively thin second cotton yarn as a weft than the modern wool, . According to an exemplary embodiment, the contemporary embroidery yarn has a thickness of 20 or less, and the first and second cotton yarns may independently have a thickness of 25 or more. In addition, the warp yarns may be woven so that the first cotton yarn has a repeating unit of 1 to 3 all to the modern single yarn count.

In addition, Hyundai Moxa according to an exemplary embodiment may include 20-30% by weight of Phellinus linteus, 30-40% by weight of cotton, and 30-45% by weight of composite fiber in total weight, Or a mixture thereof.

The absorbent pad of the present invention can be used once or repeatedly by washing and can be used as a sanitary napkin, a panty liner, a diaper or the like.

The absorbent pad according to the present invention has minimal friction with the skin and can minimize skin damage due to rash, bacterial propagation and contamination.

Also, by having improved absorption rate, ventilation and deodorizing function, it can smoothly and comfortably feel.

The present invention relates to an absorbent pad comprising a relatively thin first cotton yarn than the modern wool and modern wool and comprising a composite woven material layer having a relatively thin second cotton yarn as a weft than the modern wool, Specifically, the present invention relates to an absorbent pad which can be used, for example, as a woman's article such as a sanitary napkin, a panty liner, or a diaper. In this case, the criterion for thinness may be based on the thickness of the fiber (the diameter in the thickness direction).

Generally, friction between skin contact layer and skin due to the use of a pad occurs in an oblique direction. In order to minimize this, relatively thick fibers are used as warp yarns, and relatively thin fibers are used as weft yarns or weft yarns to form a composite weave layer so that the fibers contacting the skin are arranged in an oblique direction, The friction can be minimized, and the skin friction can be further reduced by using fibers having two different thicknesses.

As a result, ventilation and deodorization performance is improved, and skin damage due to rash, bacterial propagation, and contamination can be minimized. In addition, since the thickness of the weft and the warp are different, the body secretion and the like can be well absorbed and can have an improved water uptake, and ventilation is good and the generation of odor can be suppressed. As a result, the sanitary condition can be kept clean, and it can give a smooth and pleasant feeling.

Especially, it is possible to use environmentally friendly materials because harmful substances can be prevented from touching with skin by using modern cotton and cotton yarn. In addition, using a relatively thick modern stylus can give a softer feel when in contact with the skin. In addition, the hygroscopic hygroscopicity, the first cotton yarn and the second cotton yarn are used in different thicknesses to further enhance the absorption rate of the body secretion, and the drying can be carried out quickly, thereby giving a smoother feeling. Further, the ventilation characteristic is excellent, so that the odor can be further suppressed and the deodorizing function can be obtained.

According to an exemplary embodiment of the present invention, the modern wax can have a thickness of 20 or less, and the first face yarn and the second face yarn may independently have a thickness of 25 or more. By using fibers having different thicknesses as described above, it is possible to improve the absorptivity and the ventilation performance, and the generation of odor can be suppressed. In this case, the lower limit of the thickness of the modern model may be the maximum thickness of the modern model commonly used in the art. For example, the upper limit of the first face yarn and the second face yarn thickness may be 5 or more, The minimum thickness of the cotton yarn may be 80, for example.

More preferably, the thickness of the modern cotton yarn is 10 to 20, the thickness of the first cotton yarn and the second cotton yarn are independently 30 to 60, Two cotton yarns may be the same or different in thickness. In this case, the number is the metrical count, and the thickness when the length of the fiber having a weight of 1 kg is 1 km is assumed to be one.

More preferably, the thickness of the modern cotton yarn and the thickness of the first cotton yarn and the second cotton yarn can satisfy the following relational expressions (1) and (2).

[Relation 1]

M _R x 2? M _C1 ? M _R x 4

[Relation 2]

M _R x 2? M _C2 ? M _R x 4

(Wherein M _R is a modulus of a modern yarn, M _C1 is a modulus of a first yarn yarn, M _C2 is a modulus of a second yarn yarn, and M _C1 and M _C2 are the same or different from each other can do.)

As shown in the relational expressions 1 and 2, the absorbing pad according to an exemplary embodiment of the present invention uses a modern pad having a thickness of 2 times or more and 4 times or less the thickness of the first face yarn and the second face yarn, It is possible to prevent a single cotton yarn and a second cotton yarn from touching the skin and allow a relatively softer modern yarn to reach the skin as much as possible, thereby improving the soft feeling and effectively reducing skin irritation such as skin friction . Furthermore, a sufficient clearance is provided between the modern cotton yarn and the first cotton yarn, and between the modern cotton yarn and the second cotton yarn to improve the ventilation performance more effectively, thereby improving the deodorizing performance.

The composite woven material layer according to an exemplary embodiment of the present invention may be one having an oblique density of 100 to 150 bands / inch and a weft density of 100 to 150 bands / inch. Within this range, the absorption rate is good, and the ventilation can be effectively performed. It is especially effective in absorbing menstrual blood of women. More preferably, the composite woven material layer has a warp density of 80 to 120 yarns / inch and a weft density of 80 to 130 yarns / inch, which can further improve the water absorption and ventilation performance.

Hyundai Moss Co., Ltd. according to one embodiment of the present invention may be made of 20-30% by weight, 30-40% by weight of cottonwood, 30-45% by weight of composite fiber, and the like. By producing the modern mother liquor with the above contents, it is possible to improve the ventilation and deodorizing function, and to produce a firm, durable and soft fiber. The composite fibers may be bamboo fibers, modal fibers, rayon fibers or mixtures thereof. The composite fibers may comprise 0 to 100% by weight of bamboo fibers, 0 to 100% by weight modal fibers, 0 to 100% by weight.

The slope according to an exemplary embodiment of the present invention may be woven so that the first cotton yarn has a repeat unit of 1 to 3 all for modern hair yarns and the best cotton yarn for all modern hair yarns is 2 It is preferable to weave so as to have repeating units. By having such a repeating unit, the skin friction can be further reduced, thereby minimizing skin damage. In this case, when weaving the first cotton yarn to have a repeating unit of 4 or more with respect to the modern cotton yarn, the skin friction reduction effect and the ventilation performance improvement effect due to the difference in thickness may be small.

The absorbent pad according to an exemplary embodiment of the present invention may be used once or repeatedly by washing. When washed and used, Hyundai Corporation and cotton yarn can be used more hygienically because they have very fast drying characteristics after absorption of moisture and so on.

The absorbent pad according to an embodiment of the present invention may be manufactured by replacing the skin contact layer which is the uppermost surface of the conventional absorbent pad with the composite fabric layer of the present invention, Layer may be formed by padding. It will be understood by those skilled in the art that the absorbent pad may further have an absorbent layer and a cover layer as well as a skin contact layer.

In the present invention, unless otherwise defined, all technical and scientific terms have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Also, the singular forms as used in the specification and the appended claims are intended to include the plural forms as well, unless the context clearly indicates otherwise.

In addition, the weft and warp referred to herein may be those described in terms of absorbent pads, and the weft and warp may vary in terms of the weaving weave process. That is, the weft can be woven using the modern cotton yarn and the first cotton yarn as the weft and the second cotton yarn as the weft yarn.

The physical properties of the composite woven fabric prepared through the following Production Example 1 and Comparative Production Example 1 were measured as follows.

(Formaldehyde concentration)

It was measured by distilled water extraction according to KS K ISO 14184-1: 2009.

(Proper Formaldehyde Concentration: Infant fiber products - 20 or less, children's textile products, undergarments and medicines - 75 or less, outer garments and bedding - 300 or less)

(Hydrogen ion concentration index)

Measured according to KS K ISO 3071: 2009.

(Appropriate Hydrogen Ion Concentration Index: Children's textile products, underwear and herbal products - 4.0 ~ 7.5, outer clothing and bedding products - 4.0 ~ 9.0)

(Deodorization performance evaluation)

It was evaluated by Japan Textile Evaluation Technology Association Test Method (JTETC). A sample of 10 cm x 10 cm was placed in a 5 L Tetra bag and 3 L of gas adjusted to the initial concentration was injected. After 2 hours, the gas concentration was measured with a detector tube. (Detection tube used: Ammonia 3La)

(Evaluation of antibacterial activity)

Staphylococcus aureus (ATCC 6538) and pneumoniae (Klebsiella pneumoniae, ATCC 4352) were cultured in a test piece and a control group (cottonseed) in accordance with KS K 0693: 2011, and the viable cell count after 18 hours was confirmed. (%) Was calculated. (Mb: number of viable cells after incubation for 18 hours on the control piece, Mc: number of viable cells after 18 hours of culture)

Bacterial reduction rate (%): (Mb - Mc) x 100 / Mb

The physical properties of the sanitary napkin prepared through Example 1 were measured as follows.

(Skin friction test)

The coefficient of friction (COF) was measured using a friction device (TMI, Amityville, NY, Model 32-06). All tests were performed in a controlled environment (23 ° C and 50% relative humidity).

The friction coefficient of the sanitary napkin was measured using a moving speed of 25 cm / min, a weight of 160 g, and a puff using NBR (Nitrile Butadiene Rubber). Measurements were made by loading the treated standard cotton yarn on the test plate and measuring the load generated when the weight was moved at a constant speed after putting the weight.

[Production Example 1]

Hyundai Mossy Co., Ltd., having a thickness of 10, and a first cotton yarn and a second cotton yarn were prepared. At this time, Hyundai Moss Co., Ltd. was prepared by mixing 25 wt.% Of mossy wool, 35 wt.% Cotton and 40 wt.% Modal, based on the total weight.

Next, the composite woven fabric was woven with a modern cotton yarn and a first cotton yarn as a slope and a second cotton yarn as a weaving yarn, and in the case of a warp yarn, the first and second single yarns were weighed as a repeating unit. Further, the warp density was 100 bands / inch and the weft density was 130 bands / inch.

Table 1 and Table 2 show the deodorizing performance and antibacterial performance of the composite woven fabric produced by the above-mentioned method.

[Comparative Production Example 1]

All the procedures except for using Hyundai Mossy yarn having a thickness of 10 and 10 yarns of a first cotton yarn and a second cotton yarn were carried out in the same manner as in Production Example 1 and the deodorizing performance and antibacterial performance of the produced composite woven fabric were shown in Tables 1 and 2 .

<Deodorizing performance> Formaldehyde
(Mg / kg) Hydrogen ion concentration index
(pH) Ammonia (mg / kg) Initial concentration After 2 hours Production Example 1 Not detected

(Ma: number of viable cells immediately after inoculation of control flask / Mb: number of viable cells after 18 hours of culture of control pieces / Mc: number of viable cells after 18 hours of culture)

As shown in Table 1, it can be confirmed that formaldehyde, which is a harmful substance to human body, was not detected in the present invention, and the hydrogen ion concentration index satisfies the pH of 4.0 to 7.5 which is suitable for the undergarment.

In addition, it can be seen that the concentration of ammonia decreases to 2.1 mg / kg after 2 hours, which means that the first cotton yarn is thinner than the modern cotton yarn and the modern cotton yarn, By using cotton yarn as a weft, it can be seen that the ventilation effect is excellent, and thus it can be seen that the deodorizing performance is excellent.

On the other hand, in Comparative Production Example 1, after 2 hours, the ammonia concentration was not more than 7 times as high as that of the present invention, and the ventilation performance was not good. As a result of using Hyundai Shea, the first cotton yarn and the second cotton yarn having the same thickness, It is believed that the weaving has been woven tightly.

In the case of antibacterial performance, as shown in Table 2, it was confirmed that Production Example 1 had an excellent antibacterial performance by showing a reduction rate of bacterium of 50% or more as compared with the control. On the other hand, Comparative Production Example 1 shows that the antibacterial performance is not good due to the bacteriostatic reduction rate of 50% or less, which means that the antibacterial performance is also lowered due to insufficient ventilation.

[Example 1]

A sanitary napkin was prepared using the composite woven fabric of Preparation Example 1 as a skin contact layer. At this time, the other part of the sanitary napkin except for the skin contact layer was manufactured by a conventional method, and the sanitary napkin of the present invention was manufactured by padding the top layer of the sanitary napkin with the composite woven fabric of Production Example 1.

The coefficient of friction of the sanitary napkin made by the above-mentioned method was 21.

[Comparative Example 1]

The procedure was the same as in Example 1 except that the composite woven fabric of Comparative Preparation Example 1 was used as a skin contact layer. The friction coefficient of the sanitary napkin was 34,

[Comparative Example 2]

The procedure of Example 1 was repeated except that the composite woven fabric of Preparation Example 1 was used as a skin contact layer and the composite woven fabric was rotated at 90 ° C. The coefficient of friction of the fabric was 55.

The coefficient of friction can be used to indicate the shear forces that occur between the skin and the contact surface of the sanitary napkin. In particular, a low coefficient of friction value can indicate an increase in low shear forces and softness between the skin and the sanitary napkin.

In the case of Embodiment 1, the sanitary napkin is manufactured by using the composite woven material layer having the thickness of 10 and the first face yarn having the thickness of 30 and the second face yarn having the weft number of 30, It was possible to minimize the friction with the skin by arranging the contact fibers in the oblique direction, and the skin friction could be further reduced by using the fibers having two different thicknesses.

On the other hand, in the case of Comparative Example 1, skin friction was not reduced by using modern cotton yarn having the same thickness, first cotton yarn and second cotton yarn, and in the case of Comparative Example 2, using thick modern cotton yarn as the weft, And the friction coefficient is further increased.
