Description

  The present invention relates to a cleaning pad that is easy to use and has excellent cleaning power and antibacterial properties.

  Various types of contamination can be cleaned to some extent with water alone, but in most cases the use of detergents is required to remove the contamination. Detergents can generally be broadly classified into soaps and synthetic detergents. The soap is made by mixing animal and plant oils and sodium hydroxide as the oldest detergent and boiling, and the synthetic detergent is made by mixing various additives with surfactants made from raw materials derived from petroleum compounds.

  The surfactant, which is the main component of the soap and synthetic detergent, contains all the lipophilic groups and hydrophilic groups in the molecule, and plays an important role in removing contaminants. Specifically, if the detergent penetrates between the wash and the contaminants, the hydrophilic groups of the surfactant molecules are adsorbed and arranged while facing the water side and the lipophilic groups toward the contaminant side. To weaken the bonding force between the washed material and the contaminants, and swell the material so that it can be separated. At the same time, if a physical force is applied to the cleaning object, the contaminant can be easily removed.

  However, if the detergent is used excessively, various problems occur, especially in the case of kitchen detergents for washing dishes, because it touches the user's skin directly during use. It can be exposed to the skin and remove the protective film of the skin to induce skin diseases such as housewife eczema. Also, when left in the dishes, these detergent ingredients can be administered directly to the user orally, which can adversely affect health.

  In general, kitchen detergents are used in liquid types, but these liquid types are heavy and heavy, so they are not easy to carry or store, and it is difficult to adjust the amount during use. Used excessively than the amount. As a result, a solid type kitchen detergent was developed. However, in the case of the solid type, since it is exposed to the external environment until it is consumed after use, there is a possibility that bacteria may grow easily and hygienic management is difficult. become. In addition, the user feels inconvenience in the process of foaming while the size of the solid kitchen detergent is reduced by use.

  Accordingly, the present invention seeks to develop a cleaning pad that is capable of hygienic management of solid-type kitchen detergents and has excellent usability and cleaning power.

  The present invention is for solving the above-mentioned problems of the prior art, and the object of the present invention is to provide a solid detergent in the cleaning pad, which has excellent usability and antibacterial properties and excellent cleaning power. A cleaning pad structure is provided.

  One aspect of the present invention is a cleaning pad in which an empty space is formed therein, a detergent charging part formed at one end of the cleaning pad, and the other end of the cleaning pad extended from both ends of the detergent charging part The cleaning pad has a structure in which the detergent charging unit is folded and fixed from the outside to the inside of the cleaning pad.

  In one embodiment, the cleaning pad may be formed by folding and sewing a single textile fabric.

  In one embodiment, the fiber fabric may include an outer layer including a plurality of voids and an inner layer interposed between the outer layers, and the outer layer may be interconnected by the inner layer to have an integral structure.

  In one embodiment, the fiber fabric is selected from the group consisting of polyester yarn, polypropylene yarn, polyethylene yarn, low-density polyethylene yarn, high-density polyethylene yarn, and two or more mixed yarns thereof. There can be one.

  In one embodiment, the yarn may have a thickness of 300 to 800 denier.

  In one embodiment, the fiber fabric may have a thickness of 5 to 10 mm.

  In one embodiment, the fiber fabric may have a porosity of 10 to 30% by volume.

  In one embodiment, the cleaning pad may include a seam allowance of 5 to 15 mm.

  In the cleaning pad according to the embodiment of the present invention, an empty space is formed in the interior, and a solid detergent can be provided therein. Although easy, discharge is difficult and usability can be improved. In addition, the fiber fabric constituting the cleaning pad includes an integrated structure including voids, and excellent cleaning power can be realized by generating and maintaining abundant bubbles.

  The effects of the present invention are not limited to the effects described above, but should be understood to include all effects that can be inferred from the specific description of the present invention or the structure of the invention described in the claims. It is.

1 schematically illustrates a cleaning pad according to one embodiment of the present invention. 1 is a schematic diagram of a fiber cloth integrated structure according to an embodiment of the present invention. 1 is a cross-sectional view of a cleaning pad having a detergent charging part according to an embodiment of the present invention.

  Hereinafter, the present invention will be described with reference to the accompanying drawings. However, the invention can be embodied in a variety of different forms and, therefore, is not limited to the embodiments described herein. In order to clearly describe the present invention in the drawings, portions not related to the description are omitted, and like portions are denoted by like reference numerals throughout the specification.

  Throughout the specification, when a part is “connected” to another part, this is not only “directly connected” but also “indirectly” with another member in between. It is also included when it is connected to. Further, when a part “includes” a component, this means that the component can be further provided with other components rather than excluding other components unless specifically stated to the contrary. To do.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 schematically illustrates a cleaning pad according to one embodiment of the present invention. Referring to FIG. 1, a cleaning pad according to an embodiment of the present invention includes a cleaning pad 10 having an empty space therein, a detergent charging unit 20 formed at one end of the cleaning pad 10, and the detergent charging unit. And a sealing part 30 extending from both ends of the sealing member 20 and sealing the other end of the cleaning pad 10.

  The cleaning pad 10 can be applied to a cleaning object, i.e. tableware, and rubbed, or can remove a contaminant while rubbing. The cleaning pad 10 may be formed by folding and sewing a single fiber fabric. The fiber fabric can be folded or overlapped, and the end thereof can be sewn, and at this time, it is preferable to sew except the detergent charging part 20. The sewing can be performed with a needlework or a sewing machine, but is not limited thereto.

  In addition, the cleaning pad 10 may include a seam allowance of 5 to 15 mm. As used herein, the term “sewing allowance” refers to the width from the sewing line to the end of the fabric. The seam allowance portion may be located outside or inside the cleaning pad 10, but when the seam allowance portion is located outside the cleaning pad 10, the seam allowance portion covers the user's skin when the user cleans. Can irritate and feel skin diseases and inconvenience. Therefore, when the usability and aesthetics of the cleaning pad 10 are taken into consideration, it is preferable to arrange the seam allowance portion so as to be located inside the cleaning pad 10.

  Further, when cutting the fiber fabric, it is preferable to cut in consideration of a portion used as a seam allowance. Although the cutting standard is not defined, it is usually designed in a range of 200 to 300 mm in width and 70 to 130 mm in length on the basis of the fiber fabric in consideration of user convenience, portability and storage. Can be done.

  FIG. 2 is a schematic diagram of a monolithic structure of a fiber fabric according to an embodiment of the present invention. Referring to FIG. 2, the fiber fabric includes an outer layer 11 including a plurality of voids and an inner layer 12 interposed between the outer layers 11, and the outer layer 11 is interconnected by the inner layer 12 to have an integral structure. Can do. Specifically, an outer layer 11 provided in parallel to each other and an inner layer 12 interposed between the outer layers 11 may be included.

  The raw yarns of the inner layer 12 that connect the outer layers 11 to each other are irregularly arranged as a loose structure so that a space, that is, a gap is formed between the raw yarns, and a solid detergent is injected into the gap. Thus, bubbles can be easily generated. In addition, despite being woven as a single layer, the two outer layers 11 have a three-dimensional structure that is connected by the inner layer 12, thus providing a cushioning feeling as if the fabric is laminated in three or more layers, and having durability. And can improve cleaning power.

  The fiber fabric having such a structure can be woven by a Russell machine. The raschel machine uses a spun yarn or a filament yarn of various natural or artificial fibers as a knitting machine as a warp knitting machine, and weaves the woven fabric by combining other knitting fabrics based on chain knitting. The warp knitted fabric is a fabric in which a raw yarn is supplied from the longitudinal direction to form a loop (100p) in the longitudinal direction.

  The general weaving order of warp knitted fabrics is as follows: a crochet knitted in various laces is passed through the previous loop, a new yarn is applied to the crochet, and a new yarn is drawn into the loop to create a new loop. To reiterate, it is a chain stitch, that is, a chain stitch structure, which is a basic organization of warp knitting fabric. However, since the woven fabric cannot be formed with the basic structure alone, when creating a new loop, the left and right loops are connected to each other by weaving the guides (Guide) for supplying the knitting yarn alternately to the left and right to weave the fabric. Can be done.

  When weaving, a knitting needle and a guide for supplying knitting yarn or a knitting yarn to be supplied to the guide needle must be wound around a beam (Beam) and applied to the Russell machine at the time of weaving. The shape varies depending on the type of warp knitted fabric. When the needle shape is one row, it is called a single-row needle shape or a single needle shape. The single-needle raschel machine is called a single raschel machine, and the two-row raschel machine is called a double raschel machine.

  Since the fiber fabric has a three-dimensional structure in which two outer layers 11 are interconnected by an inner layer 12 interposed therebetween, the fiber fabric is woven as a double-row needle raschel machine rather than a single-row needle raschel machine. It is preferable.

  The outer layer 11 may have a network structure. In general, the cleaning pad serves to remove contaminants during cleaning, so that contaminants can remain after cleaning and there is a risk of bacterial growth. In addition, when washing dishes with a washing pad with bacteria, the user's bacterial infection rate is high, and it can have a fatal effect on users with low immunity, especially the elderly and children. . The outer layer 11 having the network structure, that is, the cleaning pad 10 according to the present invention, can be dried quickly after cleaning, prevent bacterial growth, and facilitate hygienic management.

  On the other hand, the fiber fabric is one selected from the group consisting of polyester yarn, polypropylene yarn, polyethylene yarn, low-density polyethylene yarn, high-density polyethylene yarn and two or more mixed yarns among them. possible.

  The polyester is a resin having excellent productivity, and a fabric produced using the polyester is excellent in durability, strong against insects, fungi, and the like, and can be stored for a long period of time. In addition, since the bonding force between atoms is high and the moisture absorption rate is low, drying is possible within a short time even when wet.

  Polypropylene is a resin that is widely used in the production of fabrics together with polyester. In particular, the polypropylene fabric has higher lightness compared to the fabric structure compared to the polyester fabric, is comfortable to wear, quickly absorbs sweat generated from the human body, and maintains a comfortable state due to the sweating effect that drains it to the outside. . Moreover, it is excellent in heat insulation and heat insulation due to low thermal conductivity, and has an antibacterial property because the moisture content is close to “0”.

  Polyethylene is a thermoplastic resin that has excellent electrical insulation properties, tensile strength, and waterproof properties, is inexpensive, easy to process, and is frequently used in daily life products.

  Depending on the density, the polyethylene may be classified into high density polyethylene (HDPE), low density polyethylene (Low Density Polyethylene, LDPE), linear low density polyethylene (Linear Low Density Polyethylene, LLDPE), and the like. The low-density polyethylene has many side chains connected to the main chain and has a low packing ability, so that there is a problem that crystallinity is lower than that of the high-density polyethylene.

  In general, the fiber yarn can be produced by spinning a melted resin composition and then drawing it. The spinning process refers to melting a polymer material that can form a fiber and extracting the yarn through fine holes. Since the fiber immediately after the spinning step has a non-uniform molecular arrangement and a low strength, the strength can be improved by stretching the fiber and adjusting the direction of the fiber.

  Therefore, a resin that is the theme of the original yarn to be manufactured can be selected, and the original yarn can be manufactured through melting, spinning, and drawing processes. In addition, as the raw yarn used in the production of the fiber fabric, a single yarn or a mixed raw yarn may be selected in consideration of physical properties, cost, and effects that can be realized from the final product.

  The yarn may have a thickness of 300 to 800 denier. If the thickness of the raw yarn is less than 300 denier (Denier), the gap of the fabric is reduced, the generation of detergent bubbles is not sufficient, the detergency is reduced, and if the denier is over 800 Denier, The gap becomes larger than necessary, and the durability of the cleaning pad is lowered.

  As used herein, the term “denier” is an internationally used unit used to indicate the length of a long filament, such as silk, noodle, among synthetic fibers, regenerated fibers, or natural fibers. If the weight of the raw yarn is 9000 m and the weight is 1 g, it is defined as 1 denier. For example, 10 denier has a weight of 10 g when the length is 9000 m, and 100 denier has a weight of 100 g when the length is 9000 m. A larger denier value means a thicker yarn, and a smaller value means a thinner yarn.

  The fiber fabric may have a thickness of 5 to 10 mm. If the thickness of the fiber fabric is less than 5 mm, the amount of the solid detergent is decreased, and the cleaning power is reduced. If the thickness is more than 10 mm, the thickness becomes unnecessarily thick and the usability is reduced.

  The fiber fabric may have a porosity of 10 to 30% by volume. If the porosity of the fiber fabric is less than 10% by volume, the amount of solid detergent input is reduced, and the cleaning power is reduced. If it exceeds 30% by volume, the durability of the cleaning pad is reduced.

  Meanwhile, an empty space is formed in the cleaning pad 10, and a solid detergent can be input into the cleaning pad 10 through the detergent input unit 20. When a solid detergent is provided in the cleaning pad 10, bubbles are continuously generated. Therefore, it is possible to improve the convenience of the user at the time of cleaning, and there is no need to provide another detergent storage case or storage space. Can be kept clean.

  If the length of the detergent charging part 20 may be 35 to 45 mm, and if the length of the detergent charging part 20 is less than 35 mm, it may be difficult to charge the solid detergent. The length of the part 20 becomes larger than necessary, and the usability is lowered.

  The size of the solid detergent can be adjusted as long as it can pass through the detergent charging unit 20, and the shape thereof is not limited. However, the solid detergent can be manufactured in a circular shape, an elliptical shape, a square shape, or the like according to the user's preference. In addition, since the solid detergent adjusted in the above range can be washed three or four times, it is convenient to carry and store, less time to be exposed to the outside, and easy hygiene management of the solid detergent. .

  In particular, the solid detergent remaining inside the cleaning pad 10 after use can suppress bacterial growth of the cleaning pad 10.

  Specifically, in the case of a general cleaning pad, it is maintained in a state of moisture after use, and if the food is not removed by the cleaning pad, bacteria can easily propagate. On the other hand, the cleaning pad according to the embodiment of the present invention can suppress the growth of bacteria because the solid detergent partially remains in the empty space inside after use. Moreover, since the said solid detergent is an amount for 3 or 4 times as above-mentioned, it can provide the washing | cleaning pad the effect of bacterial growth suppression continuously.

  The solid detergent may be a natural detergent or a synthetic detergent, but is not limited thereto, and it is preferable to use a natural detergent in consideration of user health. The natural detergents are made from natural materials and are made without adding synthetic substances such as artificial incense and preservatives. However, the natural detergents can easily become brittle, but they are environmentally friendly and protect the user's skin. There are advantages. The synthetic detergent uses additives that are not naturally decomposed, such as petrochemical surfactants and phosphates, and has excellent detergency, but may induce environmental pollution and user skin diseases.

  FIG. 3 is a cross-sectional view of a cleaning pad having a detergent charging part according to an embodiment of the present invention. Referring to FIG. 3, the detergent charging unit 20 may be configured to be folded and fixed from the outside to the inside of the cleaning pad 10. When the detergent charging unit 20 is exposed to the outside, it is easy to load the solid detergent, but it can be easily removed during use to reduce usability. Accordingly, the detergent charging unit 20 is folded from the outside to the inside of the cleaning pad 10, and is preferably folded in a triangular shape so as to be parallel to the upper end of the cleaning pad 10. Sew and fix.

  As a result, as shown in FIG. 3, the detergent charging part 20 is formed inside the cleaning pad 10, thereby forming a structure that is easy to put solid detergent into the cleaning pad but difficult to come out. The user can wash the dishes conveniently while washing.

  Examples of the present invention will be specifically described below.

[Example]
A fiber fabric having a denier density of 500 denier and a thickness of 7 mm and a porosity of 20% by volume was produced.

  The manufactured fiber fabric cut to 260 mm in width and 90 mm in length, the side surface is folded in half, and the edge of the fiber fabric excluding 40 mm of the part that creates the detergent charging part is sewn with a sewing machine inside the washing pad A free space was formed. Fold the detergent inlet in a triangular shape so that it is perpendicular to the top surface of the cleaning pad, fold it from the outside to the inside of the cleaning pad, sew and fix the bottom line of the detergent inlet to secure the cleaning pad. Manufactured.

[Comparative Example 1]
A cleaning pad was produced in the same manner as in Example 1 except that the detergent charging part was formed outside the cleaning pad.

[Comparative Example 2]
A single-type cleaning pad was manufactured in which the fabric was not sewed and the detergent charging part was not separately formed.

  [Experimental example 1: Performance evaluation of cleaning pad]

(Relative evaluation criteria: ◎ Excellent, ○ Good, △ Normal, × Bad)
Referring to Table 1, in the case of a cleaning pad manufactured by folding and fixing the detergent input part from the outside to the inside (Example), all performance evaluations (detergency, usability, hygiene, bubble generation degree) It turned out to be excellent. In particular, a solid detergent is provided inside the cleaning pad, so that abundant bubbles are generated and maintained, which makes it possible to clean the dishes without inconvenience because the cleaning power is excellent, the solid detergent cannot be removed. Is done.

  On the other hand, when the detergent charging part is exposed to the outside (Comparative Example 1), there is a problem that the solid detergent is removed during cleaning, resulting in poor usability. It was difficult and the detergency was reduced as compared with the Examples. Also, in the case of a cleaning pad made of a single fiber fabric without a detergent charging part (Comparative Example 2), the drying speed after cleaning was the fastest, but the cleaning pad was extremely thin and the gap was sufficient Therefore, the generation of bubbles is not rich and the cleaning power is relatively poor.
