Description

TECHNICAL FIELD

[0001] The present disclosure relates to a double-sided scrubber and a method of manufacturing the same.BACKGROUND

[0002] For example, a multifunctional double-sided scrubber whose both sides may be used for different purposes has been developed and is being used. In such a double-sided scrubber whose both sides are made of different materials, one side may be used to perform a function of washing a food dish or the like, and the other may be used to perform a function of rinsing the food dish or the like.

[0003] Korean Patent Application No. 2018-0002840 filed by the present inventors discloses a multifunctional double-sided scrubber. This scrubber includes: a washing part whose a first side is woven with first and second mesh yarn made of different materials to form a plurality of first mesh chains and a plurality of first mesh spaces; a rinsing part whose a second side is woven with a third mesh yarn to form a plurality of second mesh chains and a plurality of second mesh spaces; and a gap holding part having a plurality of connection yarns to connect the washing part and the rinsing part to be spaced apart by a certain distance from each other. Thus, a cushion effect may be provided between the two sides by the connection yarns, and a washing liquid may be appropriately held between the two sides, thereby improving washability.

[0004] However, a scrubber in the related art may be slid and separated from his / her hand due to poor grip force. This may reduce the washability and may cause a phenomenon in which food residue gets stuck in the scrubber. This results in inconvenience to use.

[0005] In general, the scrubber is used while being soaked in the washing liquid. When a large area of mesh spaces is formed for an improvement of grip feel and contamination prevent, the washability may be reduced. To solve this, in the scrubber in the related art, the area of the mesh spaces is decreased to hold the washing liquid for a long period of time. This improves the washability but results in a deterioration of the grip feel. In addition, since the food residue is hard to be separated from the scrubber, the scrubber is likely to be contaminated.

[0006] On the other hand, attempts have been made in recent years to manufacture a scrubber by weaving a yarn made of a biodegradable eco-friendly material, for example, poly lactic acid (PLA), from the viewpoint of reinforced environmental protection.

[0007] However, when the scrubber in the related art is manufactured using such an eco-friendly material, it does not provide sufficient grip feel. Further, foam absorption ability may be reduced compared to a case in which the scrubber is manufactured using polypropylene (PP), which further reduces the washability. Accordingly, an improvement of the scrubber in the related art may provide various benefits to a user.SUMMARY

[0008] The present disclosure is for the purpose of providing a double-sided scrubber which is capable of providing an improved grip feel and washability and minimizing contamination.

[0009] The present disclosure is for the purpose of providing a double-sided scrubber which is capable of being manufactured using a material made of PLA.

[0010] The present disclosure is for the purpose of providing a double-sided scrubber which is capable of suppressing both of the washability and the grip feel from being reduced even if the double-sided scrubber is manufactured with the material made of PLA.

[0011] A double-sided scrubber according to an example embodiment may include: a first fabric woven with a first yarn, and including a plurality of fabric portions and a plurality of openings, which are formed to be arranged continuously over an entire surface of the first fabric; a second fabric woven with a first yarn and a second yarn made of different materials, and including a plurality of fabric portions and a plurality of openings, which are formed to be arranged continuously over an entire surface of the second fabric; and connection yarns configured to connect the first fabric and the second fabric so that the first fabric and the second fabric are spaced a certain interval apart from each other.

[0012] In an aspect, a size of each of the plurality of opening of the first fabric or the second fabric may be in a range of 6 to 9 millimeter (mm).

[0013] In an aspect, a width of each of the plurality of fabric portions of the first fabric or the second fabric may be in a range of 4 to 6 mm.

[0014] In an aspect, the first yarn of the first fabric or the second fabric may be made of poly lactic acid (PLA).

[0015] In an aspect, the plurality of fabric portions may be sparsely woven such that voids are formed between the plurality of fabric portions, and an area of the voids may be 30 to 50 percentage (%) of an area of the plurality of fabric portions.

[0016] In an aspect, the double-sided scrubber may have a structure in which end portions of the first fabric and the second fabric are connected to each other by sewing or fusing.

[0017] In an aspect, each of the plurality of openings may have a circular or hexagonal shape.

[0018] In an aspect, the first yarn may be made of acrylic or polypropylene, and the second yarn may be made of a film material having a larger surface roughness than the first yarn.

[0019] A method of manufacturing a double-sided scrubber according to another example embodiment may include: fabricating a first fabric woven with a first yarn, and including a plurality of fabric portions and a plurality of openings, which are formed to be arranged continuously over an entire surface of the first fabric; fabricating a second fabric woven with a first yarn and a second yarn made of different materials, and including a plurality of fabric portions and a plurality of openings, which are formed to be arranged continuously over an entire surface of the second fabric; and connecting, with connection yarns, the first fabric and the second fabric so that the first fabric and the second fabric are spaced a certain interval apart from each other.

[0020] In an aspect, in the fabricating the first fabric or the second fabric, the first fabric or the second fabric is fabricated by weaving a yarn made of PLA. The method may further include: performing a heat treatment on the double-sided scrubber manufactured by weaving the yarn made of PLA.

[0021] In an aspect, the heat treatment may be performed at a temperature of 130 to 150 degrees C. and a conveyance speed of 25 to 30 meter / minute.

[0022] According to an example embodiment, it is possible to increase an area of fabric portions to provide an improved grip feel.

[0023] Further, by sparsely weaving the fabric portions to sufficiently increase an area of voids, it is possible to sufficiently absorb foams and increase washability even if the double-sided scrubber is manufactured with a yarn made of PLA.

[0024] In addition, by further increasing an area of openings in a fabric surface to improve the grip feel and to easily discharge food residue, it is possible to minimize contamination of a double-sided scrubber. Further, by increasing the area of the fabric portions as described above, it is possible to suppress a deterioration of the washability even if a size of the openings is large.

[0025] Further, by using the yarn made of PLA as a biodegradable eco-friendly material, it is possible to manufacture the double-sided scrubber having good washability and grip feel.

[0026] Further, by manufacturing the double-sided scrubber with the eco-friendly material, it is possible to suppress environmental contamination.BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Hereinafter, example embodiments of the present disclosure will be described in detail. However, the example embodiments of the present disclosure are merely exemplary and are not intended to limit the scope of the present disclosure to only the described example embodiments. The present disclosure is merely defined by the scope of the claims. The present disclosure is not limited to example embodiments which will be described later, and may be implemented in various different forms without departing from the appended claims and the gist thereof. Throughout the specification, the same reference numerals are assigned to the same or corresponding components.

[0032] Terminologies used herein are for the purpose of merely describing example embodiments, but may not be construed in a limited way. The singular form described herein may include the plural form unless the context clearly dictates otherwise. The expression “comprises”, “includes” or the like are intended to include specific features, regions, integers, operations, actions, elements and / or components, but may be constructed not to exclude one or more other features, regions, integers, operations, actions, elements, components and / or a combination thereof in addition to the above-described terminologies.

[0033] Hereinafter, preferable example embodiments of the present disclosure will be described with reference to the accompanying drawings. However, the example embodiments of the present disclosure are merely exemplary and are not limited thereto.

[0034] FIG. 1 illustrates a cross-sectional structure of a double-sided scrubber according to an example embodiment. FIGS. 2 and 3 illustrate both sides of the double-sided scrubber according to an example embodiment, respectively.

[0035] As illustrated in the figures, a double-sided scrubber 10 according to an example embodiment may include: a first fabric 20 which is woven with a first yarn 21 and has a plurality of fabric portions 22 and a plurality of openings 24 formed continuously on the entire surface thereof; a second fabric 30 which is woven with first and second yarns 31 and 33 made of different materials and has a plurality of fabric portions 32 and a plurality of openings 34 formed continuously over the entire surface thereof; and a plurality of connection yarns 40 which connects the first fabric 20 and the second fabric 30 to be spaced apart by a certain distance from each other.

[0036] FIG. 1 illustrates a partial cutaway cross-sectional view of both end portions of the double-faced scrubber 10. The double-sided scrubber 10 may have a structure in which the end portions of the first fabric 20 and the second fabric 30 are connected to each other and integrated by sewing or fusing. The double-faced scrubber 10 may have, for example, a rectangular shape, and a size or overall shape thereof may be variedly changed.

[0037] The first fabric 20 and the second fabric 30 may be similar in structure or pattern to each other except that they are woven with different yarns. Of course, in another example embodiment, the first fabric 20 and the second fabric 30 may have the same structure using the same yarns instead of the above-described structure.

[0038] The first fabric 20 is formed by weaving the first yarn 21. In an example embodiment, the first yarn 21 may be formed of an original yarn made of poly lactic acid (PLA). The original yarn made of PLA is a biodegradable eco-friendly material. As described above, the double-sided scrubber 10 according to an example embodiment is manufactured with the original yarn made of PLA, which makes it possible to minimize environmental contamination.

[0039] The first fabric 20 may be formed by weaving the first yarn 21 such that the fabric portions 22 and the openings 24 are arranged alternately over the entire surface. Here, the fabric portions 22 may refer to faces obtained by weaving the first yarn 21, and the openings 24 may refer to holes formed between the fabric portions 22 adjacent to each other.

[0040] In an example embodiment, each of the openings 24 may be formed in an approximately hexagonal shape.

[0041] As illustrated in FIG. 3, the second fabric 30 may be formed by weaving a first yarn 31 and a second yarn 33 in a mixing manner such that the openings 34 and the fabric portions 32 are formed. The openings 34 and the fabric portions 32 are formed to be arranged continuously over the entire surface of the second fabric 30.

[0042] The first yarn 31 used for the second fabric 30 may have the same structure as that of the first yarn 21 used for the first fabric 20. Hereinafter, a detailed description on the first yarn 31 used for the second fabric 30 will be omitted.

[0043] The second yarn 33 may be made of an original yarn having a relatively large surface roughness than the first yarn 21. For example, the second yarn 33 may be made of an original yarn produced by film material yarn.

[0044] The second yarn 33 may have the structure in which the first yarn 31 and the second yarn 33 made of different materials are woven. By using the second yarn 33 of the relatively large surface roughness, foreign matters adhering to a surface of a food dish may be more easily removed.

[0045] In the second fabric 30, the fabric portions 32 woven by the first yarn 31 and the second yarn 33, and the openings 34 are arranged alternately over the entire surface of the second fabric 30. Like the first fabric 20, each of the openings 34 formed in the second fabric 30 may also be formed in an approximately hexagonal shape.

[0046] The fabric portions 32 and the openings 34 of the second fabric 30 are similar in size and shape to the fabric portions 22 and the openings 24 of the first fabric 20. Further, the second fabric 30 may be coupled to the first fabric 20 in a state in which the fabric portions 32 and the openings 34 of the second fabric 30 face the fabric portions 22 and the openings 24 of the first fabric 20 at the same positions, respectively. With this configuration, a user may get the same grip feel even if he / she holds either side of the double-sided scrubber 10. Further, food residue, which is introduced through the openings 24 of the first fabric 20 (or the openings 34 of the second fabric 30), may be easily discharged through the openings 34 of the second fabric 30 (or the openings 24 of the first fabric 20) which face each other. This makes it possible to prevent the double-faced scrubber 10 from being contaminated due to the introduced food residue.

[0047] The first fabric 20 and the second fabric 30 are connected to each other by the plurality of connection yarns 40. The first fabric 20 and the second fabric 30 may be connected to each other while being spaced apart by a certain distance from each other by the plurality of connection yarns 40.

[0048] The connection yarns 40 may have a structure in which the fabric portions 22 of the first fabric 20 are connected to the fabric portions 32 of the second fabric 30, which are located directly below the respective fabric portions 22.

[0049] The connection yarn 40 may be fabricated with an original yarn made of, for example, polyethylene terephthalate (PET) or polypropylene. In an example embodiment, the connection yarn 40 may have a diameter of 0.05 to 0.20 millimeter (mm).

[0050] The first fabric 20 and the second fabric 30 may be spaced apart from each other in an elastic manner by the connection yarns 40. Thus, an elastic force may be provided to the double-sided scrubber 10 and a space may be formed between the first fabric 20 and the second fabric 30. With this configuration, the double-sided scrubber 10 may be brought into contact with objects to be washed with appropriate force. Further, a washing liquid or the like may be held in the space, which minimizes consumption of the washing liquid.

[0051] As illustrated in FIG. 2, in an example embodiment, a size L of each opening 24 of the first fabric 20 may be in a range of 6 mm to 9 mm, and a width D of the fabric portion 22 may be in a range of 4 mm to 6 mm. Specifically, the size L of the opening 24 may be in the range of 8 mm to 9 mm, and the width D of the fabric portion 22 may be in the range of 5 mm to 6 mm. Each opening 34 and each fabric portion 32 of the second fabric 30 may also have the same size and width as those of the first fabric 20. Hereinafter, the first fabric 20 will be described as an example with reference to FIG. 2.

[0052] As illustrated in FIG. 2, the side L of the opening 24 may refer to a diameter of a circumscribed circle obtained by connecting vertices of the opening 24 of the substantially hexagon shape. The width D of the fabric portion 22 may refer to a length of the fabric portion 22 between the openings 24 adjacent to each other.

[0053] As described above, by forming each of the openings 24 to have the size L in a relatively wide range of 6 mm to 9 mm, foreign matters such as the food residue may be easily discharged via the openings 24 when washing the food dish or the like. This makes it possible to prevent the food residue introduced into the first fabric 20 or the second fabric 30 from staying in an interior of the first fabric 20 or the second fabric 30, which prevents the double-sided scrubber 10 from being contaminated. Further, by widening the size L of each opening 24, it is possible to provide an enhanced grip feel to the user. The term “grip feel” used herein may refer to a textile sensation the user feels when holding the scrubber with his / her hand, specifically, when his / her hand is brought into contact with sides of the scrubber without being easily separated from his / her hand. In a state where the grip feel is poor, the double-sided scrubber 10 may be prone to be separated. As a result, the user may not use the double-sided scrubber 10 as he / she wants, which makes it difficult to thoroughly perform a washing work.

[0054] When the size L of the opening 24 is smaller than 6 mm, the grip feel may be reduced. This makes the washing work difficult. When the size L of the opening 24 is larger than 9 mm, the washability may be reduced.

[0055] Further, as described above, unlike the case where the fabric is fabricated with PP, in the case where the fabric is fabricated with the original yarn made of PLA, the grip feel may be reduced due to characteristics of the original yarn, and a foam absorption ability may be reduced, which deteriorates the washability.

[0056] In an example embodiment, when the fabric portion 22 is formed to have the width D in the range of 4 mm to 6 mm, even if the fabric portion 22 is fabricated with PLA, it is possible to provide an improved grip feel and enhance a detergent foam absorption ability, which improves the washability. Further, when the width D of the fabric portion 22 is increased, an effect of sewing the end portions of the first fabric 20 and the second fabric 30 may be easily obtained.

[0057] When the width D of the fabric portion 22 is less than 4 mm, an area of the fabric portion 22 becomes too small. This reduces the grip feel and decreases an amount of the foams to be absorbed, thereby deteriorating the washability. When the width D of the fabric portion 22 is more than 6 mm, the openings 24 are hard to be sufficiently formed over the entire surface of the fabric. This may deteriorate the overall grip feel and may increase a contamination level of the double-sided scrubber 10. In addition, a manufacturing cost may be increased due to an increase in yarn usage.

[0058] FIG. 4 illustrates a fabric structure of the first fabric of FIG. 4.

[0059] As illustrated in FIG. 4, the fabric portion 22 of this example embodiment may be sparsely woven to form voids G and may have a structure in which an area of the voids G is 30 to 50 percentage (%) of the area of the fabric portion 22.

[0060] Although not illustrated, like the first fabric 20, the fabric portion 22 of the second fabric 30 may also be formed such that the area of the voids G is 30 to 50% of the area of the fabric portion 22.

[0061] Hereinafter, the fabric portion 22 of the first fabric 20 will be described with reference to FIG. 4 and a structure of the fabric portion 32 of the second fabric 30 will be omitted.

[0062] In the fabric portion 22, gaps between adjacent first yarns 21 which are woven with each other are sparsely open to form the voids G. The voids G may be open areas, which become spaces into which detergent foams are introduced. As described above, a relatively large amount of foams of the washing fluid is introduced into the voids G of the fabric portion 22 where the foams are held by the voids G. This increases the washability.

[0063] When the area of the voids G is 30% smaller than the area of the fabric portion 22, the foam absorption ability may be reduced, resulting in a poor washability. When the area of the voids G is 50% higher than the area of the fabric portion 22, a strength of the fabric portion 22 may be reduced and the durability of the double-sided scrubber 10 may be weakened. This may significantly shorten the lifetime of the double-sided scrubber 10.

[0064] Next, a method of manufacturing the double-sided scrubber according to an example embodiment will be described.

[0065] The method of manufacturing the double-sided scrubber according to an example embodiment with the yarn made of PLA as described above may further include finally performing a heat treatment on the double-sided scrubber 10 manufactured with the first fabric 20 or the second fabric 30 formed by weaving the yarn made of PLA.

[0066] In an example embodiment, the heat treatment may be performed on the double-sided scrubber 10 which is being conveyed at a conveyance speed of 25 to 30 meter / minute inside a heating furnace at a temperature of 130 to 150 degrees C. When the double-sided scrubber 10 manufactured with the yarn made of PLA is finally subjected to the heat treatment, the form of the double-sided scrubber 10 may be stabilized.

[0067] When the temperature of the heat treatment is lower than 130 degrees C. or when the conveyance speed is higher than 30 meter / minute, the heat treatment may not be properly performed. This makes the first fabric 20 or the second fabric 30 too mushy. As a result, the double-faced scrubber 10 does not have a stable form.

[0068] When the temperature of the heat treatment is more than 150 degrees C. or when the conveyance speed is smaller than 25 meter / minute, a phenomenon may occur in which the first fabric 20 or the second fabric 30 is hardened and broken due to an overheat treatment at high temperature.

[0069] By finally performing the heat treatment on the double-sided scrubber 10 at an appropriate temperature in this way, it becomes possible to stably manufacture the double-faced scrubber 10 made of PLA.EXPERIMENTAL EXAMPLE

[0070] The double-faced scrubber according to an example embodiment was manufactured with the yarn made of PLA.

[0071] Comparative experiment was conducted on the scrubber manufactured according to this example embodiment and a scrubber manufactured according to Comparative example in terms of four items such as washability, contamination level, grip feel, and foamability.

[0072] In the experiment on the washability, samples contaminated at the same degree were washed under the same conditions to check a contamination level of the samples. Evaluation results are represented as values obtained by expressing the contamination level of the samples in terms of a percentage (%). For example, 100% indicates a state in which the contamination was completely removed, 90% indicates a state in which only 10% of the contamination was removed, and 0% indicates a state in which the contamination was not removed at all.

[0073] In the experiment on the contamination level, a procedure of cooking rice and washing a rice cooker was repeated about 10 times to check the presence or absence of rice grains remaining in the scrubber. Evaluation results are represented as numerical values indicating the contamination level. The numerical value of the contamination level was given as 10 points when no rice grains remained or when almost no residual amount was checked. Points were increased or decreased according to the residual amount.

[0074] The experiment on the grip feel was conducted with 50 participants (users). In this experiment, each participant repeatedly rubbed the scrubber while holding the scrubber soaked in the same amount of detergent with his / her hand to check the user's feel about the scrubber. Evaluation results were represented as satisfactions specified by the users. When the satisfaction is high, 10 points were given. As the satisfaction decreases, points were decreased.

[0075] In the experiment on the foamability, the users rubbed the scrubber soaked in the same amount of detergent with his / her hand 10 times to produce foams. In this state, a height at which the foams are formed was measured. Evaluation results were represented as values obtained by measuring the height of the foams formed at a surface of the scrubber.TABLE 1OpeningContaminationGripSectionsize (mm)WashabilitylevelfeelComparative410065Example 1Comparative510088Example 2Example 161001010Example 271001010Example 38951010Example 49901010Comparative10861010Example 3Comparative1180109Example 4

[0076] In Comparative examples and Examples listed in Table 1, the scrubbers were manufactured to have different sizes of openings and have the same structure except for the size of the opening.

[0077] As listed in Table 1, it was found that the contamination level and the grip feel are reduced due to a relatively small size of opening in Comparative Examples 1 and 2 rather than Examples. In Examples, it was found that the contamination level is good at a level of 9 or more, and satisfactory results are obtained even in terms of the washability and the grip feel. In contrast, it was found in Comparative Examples 3 and 4 that the washability is significantly poor.TABLE 2FabricContam-widthinationGripSection(mm)WashabilitylevelfeelFoamabilityComparative280950.9Example 1Comparative3921081.5Example 2Example 1410010103.1Example 2510010103.2Example 361009103.2Comparative71007103.0Example 3Comparative81005103.0Example 4

[0078] In Comparative examples and Examples listed in Table 2, the scrubbers were manufactured to have different fabric widths and have the same structure except for the fabric width.

[0079] As listed in Table 2, it was found that the washability and the grip feel are reduced due to a relatively narrow fabric width in Comparative Examples 1 and 2 rather than Examples. In Examples, it was found that the contamination level is good at a level of 9 or more, and satisfactory results are obtained even in terms of the washability and the grip feel. In contrast, it was found in Comparative Examples 3 and 4 that the contamination level is significantly poor.

[0080] For the foamability, it was found that the foams are formed at a height of 3 mm or more in Examples and are formed at a height of approximately 1 mm in Comparative Examples 1 and 2. Accordingly, it can be seen in all Examples that the foams are formed at a height of 3 mm or more and satisfactory results are obtained in terms of the foamability.TABLE 3VoidContaminationGripSection(%)WashabilitylevelfeelFoamabilityComparative10801050.9Example 1Comparative20921081.5Example 2Example 13010010103.1Example 24010010103.2Example 35010010103.2Comparative551008103.0Example 3Comparative601005103.0Example 4

[0081] In Comparative examples and Examples listed in Table 3, the scrubbers were manufactured to have different void areas and have the same structure except for the void area.

[0082] As listed in Table 3, it was found that the washability, the grip feel and the foamability are reduced due to a relatively small void area in Comparative Examples 1 and 2 rather than Examples. In Examples, it was found that all parameters are good. For the foamability, it was found that the foams are formed at a height of 3 mm or more in Examples and are formed at a height of approximately 1 mm in Comparative Examples 1 and 2.
