Description

Wash pad

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

Various contaminations 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 divided into soaps and synthetic detergents. The soap is the oldest detergent made by mixing oil and animal oil and sodium hydroxide, and the synthetic detergent is made by mixing various additives with a surfactant made from a petroleum compound.

The surfactant, which is a main component of the soap and synthetic detergent, contains both a lipophilic group and a hydrophilic group in a molecule, and thus plays an important role in removing contaminants. Specifically, when the detergent penetrates between the wash and the contaminant, the hydrophilic groups of the surfactant's molecules are directed towards the water and the lipophile toward the contaminants, adsorbing and arranging to weaken and swell the bond between the wash and the contaminants. Make it as possible. In addition, applying physical force to the wash can easily remove contaminants.

However, excessive use of detergents may cause various problems. In particular, kitchen detergents for washing dishes are directly exposed to the user's skin during use. It can cause skin diseases such as back. In addition, when remaining in the tableware such a detergent component is directly administered orally of the user may adversely affect health hygiene.

In general, kitchen detergents are used as a liquid type, and such liquid types are not easy to carry and store because of their high weight and weight, and are difficult to control when used. Accordingly, although the kitchen cleaner of the solid type has been developed, since the solid type is exposed to the external environment until it is consumed after use, it may be difficult to propagate bacteria and thus hygienic management may be difficult. In addition, as the size of the solid type kitchen detergent decreases with use, the user may feel uncomfortable in the process of foaming.

Therefore, while maintaining a hygienic management of a solid type kitchen detergent, to develop a cleaning pad excellent in usability and cleaning power.

The present invention is to solve the above-mentioned problems of the prior art, the object of the present invention can be provided with a solid detergent in the cleaning pad, including the excellent usability and antimicrobial properties and at the same time provides a structure of the cleaning pad excellent in washing power will be.

Hereinafter, with reference to the accompanying drawings will be described the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is "connected" to another part, it includes not only "directly connected" but also "indirectly connected" with another member in between. . In addition, when a part is said to "include" a certain component, this means that it may further include other components, without excluding the other components unless otherwise stated.

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

1 is a schematic of the cleaning pad according to an embodiment of the present invention. Referring to FIG. 1, the cleaning pad according to an embodiment of the present invention includes a cleaning pad 10 having an empty space therein; A detergent input part 20 formed at one end of the cleaning pad 10 and a sealing part 30 extending from both ends of the detergent input part 20 to seal the other end of the cleaning pad 10; It may include.

The cleaning pad 10 may serve to remove contaminants while rubbing or rubbing by applying to washing products, that is, dishes. The cleaning pad 10 may be formed by folding and sewing a single fiber fabric. The fiber fabric may be folded or folded to sew its edges, and at this time, it is preferable to sew except the detergent inlet 20. The sewing may be performed by sewing 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 "seam seam" refers to the width from the sewing line to the end of the fabric. The seam seam may be located outside or inside the cleaning pad 10, but if the seam seam is located outside the washing pad 10, the seam seam may irritate the skin of the user when the user washes, thereby causing skin disease and discomfort. I can feel it. Therefore, in consideration of the usability and aesthetics of the cleaning pad 10, it is preferable to arrange the seam contact portion to be located inside the cleaning pad 10.

In addition, it is preferable to cut in consideration of the portion to be used as a seam seam when cutting the textile fabric. The cutting standard is not defined, but in general, in consideration of the user's convenience, portability and storage, it can be designed in the range of 200 to 300 mm in width and 70 to 130 mm in length based on the fiber fabric.

Figure 2 is a schematic diagram of the integral structure of the fiber fabric according to an embodiment of the present invention. Referring to FIG. 2, the textile fabric includes an outer layer 11 including a plurality of voids and an inner layer 12 interposed between the outer layer 11, and the outer layer 11 is attached to the inner layer 12. Interconnected by each other to have an integral structure. In detail, it may include an outer layer 11 parallel to each other and an inner layer 12 interposed between the outer layers 11.

Yarns of the inner layer 12 interconnecting the outer layer 11 are irregularly arranged in a loose structure so that spaces, that is, voids may be formed between the yarns, and a solid detergent is introduced into the voids, thereby facilitating foaming. Can be generated. In addition, since the outer layer 11 has a three-dimensional structure connected by the inner layer 12 even though the single layer is woven, it is possible to improve durability and washing power by providing a cushioning feeling as in the case of stacking three or more layers of fabrics.

The fiber fabric of this structure can be woven by a Raschel group. The Raschel group is a knitting machine of warp knitting fabrics, and weaving the fabric by using spun yarn or filament yarn of various fibers of natural or artificial fibers in knitting yarns and combining other weaving structures based on chain weaving. A warp knitted fabric is a fabric in which yarn is fed from the longitudinal direction to form a loop in the longitudinal direction.

The usual weaving sequence of warp knitted fabrics is to weave crochet stitches from various laces in the front loops, hang new yarns on the crochet hooks, pull out the yarns into the loops, and create new loops. It is a chain knit and this is the basic structure of warp knitted fabric. However, it is not possible to form the fabric by the basic tissue alone, and by alternately shifting the guides for supplying the knitting yarn when making a new loop, the left and right loops can be connected to each other and the fabric can be woven.

The weaving machine has to wrap the knitting yarns to be supplied to the guides or guide needles that supply the knitting needles and knitting yarns when weaving them, and to hang the knitting machine on the beams. Do. If a single row of beds is called a single row or single bed. The single needle-shaped raschel group is called a single raschel group, and the two-row needle-shaped raschel group is called a double raschel group.

Since the fiber fabric has a three-dimensional structure interconnected by the inner layer 12 interposed between the two outer layers 11, it is preferable that the textile fabric is woven with a double-row needle-like double-lasel group rather than a single-row needle-like single-cell machine. .

In addition, the outer layer 11 may have a mesh structure. In general, since the washing pad plays a role of removing contaminants during washing, contaminants may remain after washing, and there is a risk of bacterial propagation. In addition, when washing dishes with a bacterial propagation washing pad, the bacterial infection rate is increased by the user, and in particular, may have a fatal effect on users with low immunity, such as the elderly and children. The outer layer 11 of the mesh structure, that is, the washing pad 10 of the present invention can be quickly dried after washing to prevent bacterial propagation, and can be easily hygienic.

Meanwhile, the fiber fabric may be one selected from the group consisting of polyester yarns, polypropylene yarns, polyethylene yarns, low density polyethylene yarns, high density polyethylene yarns and mixed yarns of two or more thereof.

The polyester (Polyester) is a resin with excellent productivity, the fabric produced by using it is excellent in durability, strong for insects, molds, etc., easy to store for a long time. In addition, the bond strength between atoms is high, so the water absorption rate is low, and drying in a short time even when wet.

The polypropylene is a resin that is widely used in manufacturing fabrics with polyester. In particular, the polypropylene fabric is lighter than the fabric structure compared to the polyester fabric is excellent in wearing comfort, and can always maintain a comfortable state due to the sweat effect to quickly absorb and discharge the sweat generated in the human body to the outside. In addition, the thermal insulation is excellent due to the low thermal conductivity, the moisture content is close to '0' is excellent antibacterial.

The polyethylene (polyethylene) is a thermoplastic resin, has excellent electrical insulation, toughness, water resistance, low cost and easy processing, it is used in many daily necessities.

The polyethylene may be classified into high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), and the like according to the density. The low-density polyethylene has a problem in that crystallinity is lower than that of the high-density polyethylene due to its low packing capacity due to a large number of side chains connected to the main chain.

In general, the yarn is generally fiber yarn can be produced by spinning after stretching the molten resin composition. Spinning process refers to melting a polymer material that can make a fiber and drawing a thread through a minute hole. Since the fibers immediately after the spinning process have a nonuniform molecular arrangement and weak strength, the fibers can be stretched to adjust the orientation of the fibers to improve the strength.

Therefore, it is possible to select a resin that is the subject of the yarn to be manufactured, and to manufacture the yarn through melting, spinning, and stretching processes. In addition, the yarn used in the manufacture of the fiber fabric may be selected singly or mixed yarn in consideration of the properties, cost, and effects that can be implemented from the final product.

The thickness of the yarn may be 300 to 800 denier (denier). If the thickness of the yarn is less than 300 denier (denier), the voids of the fabric is small, the generation of detergent bubbles may not be enough, the washing power may be lowered, if more than 800 denier (denier) the voids are larger than necessary to the cleaning pad The durability of the can be lowered.

As used herein, the term “denier” is an international unit used to express the thickness of long filaments such as silk, among synthetic fibers, recycled fibers, or natural fibers. If it is 1 g, it is defined as 1 denier. For example, 10 denier (denier) is the weight of the yarn when the length is 9000m, 10g, 100 denier (denier) is the weight of the yarn 100g when the length is 9000m. The larger the denier value, the thicker the yarn, the smaller the yarn.

The fiber fabric may have a thickness of 5 to 10 mm. If the thickness of the fiber fabric is less than 5mm, the amount of the solid detergent is reduced, the washing power may be lowered, if it is more than 10mm thickened more than necessary, the usability may be reduced.

The porosity of the fiber fabric may be 10 to 30% by volume. When the porosity of the fiber fabric is less than 10% by volume, the amount of the solid detergent may be reduced, and thus the washing power may be lowered. When the fiber cloth is more than 30% by volume, the durability of the cleaning pad may be lowered.

On the other hand, the washing pad 10 may be an empty space formed therein, the solid detergent may be introduced into the cleaning pad 10 through the detergent inlet 20. If a solid detergent is provided inside the washing pad 10, bubbles may be continuously generated, and thus the convenience of the user may be improved during washing, and the kitchen does not need to have a separate detergent storage box or storage space. Can keep the environment clean.

The detergent inlet 20 may have a length of 35 to 45 mm, and when the length of the detergent inlet 20 is less than 35 mm, it may be difficult to add a solid detergent. ) Length is larger than necessary, and usability may fall.

The solid detergent may be adjusted in a size that can pass through the detergent inlet 20, the shape is not limited, it can be made in accordance with the preference of the user in a circle, oval, square, and the like. In addition, the solid detergent adjusted to the above range may be three to four times the amount of washing, it is convenient to carry and store, less time to be exposed to the outside can be easily hygienic management of the solid detergent.

In particular, the solid detergent remaining in the washing pad 10 after use may inhibit bacterial growth of the washing pad 10.

Specifically, in the case of a general washing pad, it is kept in a wet state after use, and bacteria can easily grow when food is not removed from the washing pad. On the other hand, the washing pad according to an embodiment of the present invention, since the solid detergent remains in the empty space therein after use, it is possible to suppress the growth of bacteria. In addition, since the solid detergent is 3 to 4 times as described above, the washing pad can continuously provide the effect of inhibiting the growth of bacteria.

The solid detergent may be a natural detergent or a synthetic detergent, but is not limited thereto. It is preferable to use a natural detergent in consideration of the user's health. The natural detergent is made of a natural material and manufactured without adding synthetic materials such as artificial flavors and preservatives, but has a disadvantage in that it is easily softened, but it has advantages in environment-friendly and user's skin protection. The synthetic detergent has excellent washing power by using additives that are not decomposed in a natural state such as petrochemical surfactants and phosphates, but may cause environmental pollution and skin diseases of users.

Figure 3 is a cross-sectional view of the cleaning pad formed detergent input unit according to an embodiment of the present invention. Referring to FIG. 3, the detergent inlet 20 may be a structure that is folded and fixed from the outside to the inside of the cleaning pad 10. When the detergent inlet 20 is exposed to the outside, it is easy to add a solid detergent, but can be easily escaped during use to reduce usability. Therefore, the detergent inlet 20 is folded from the outside to the inside of the washing pad 10, preferably folded in a triangular form, the detergent inlet 20 to be parallel to the upper end of the washing pad 10 Sewn the bottom line of) and fix it.

Accordingly, as shown in FIG. 3, the detergent inlet 20 is formed inside the cleaning pad 10, so that the solid detergent is easily added to the inside of the cleaning pad but is difficult to come out. The user can conveniently wash dishes even during washing.

Hereinafter, embodiments of the present invention will be described in detail.

Example

A fibrous fabric having a thickness of 7 mm and a porosity of 20% by volume was prepared from 500 denier high density polyethylene yarn.

The fabric was cut into 260 mm and 90 mm lengths, and the edges of the fabric were sewn with a sewing machine, except for 40 mm of the part where the detergent input was made. Formed. The detergent input unit was folded in a triangular shape so as to be perpendicular to the upper surface of the cleaning pad, folded from the outside of the cleaning pad toward the inside, and the bottom line of the detergent input unit was sewn to fix the washing pad.

Comparative Example 1

A washing pad was prepared in the same manner as in Example 1, except that the detergent inlet was formed on the outside of the washing pad.

Comparative Example 2

Since the fabric was not sewn, a detergent pad was prepared in a single layer of washing pads not separately formed.

(Relative evaluation criteria: ◎ Excellent, ○ Good, △ Normal, × Poor)

Referring to Table 1, the detergent pads were folded and fixed from the outside to the inside (example) in the case of the manufacturing of the cleaning pad (Example) was found to be excellent in all performance evaluation (washing power, usability, hygiene, foaming degree). Particularly, since the solid detergent is provided inside the washing pad, the foam is generated and maintained in abundance, and thus, the washing power is excellent, and the solid detergent does not come out so that the user can wash the dishes without inconvenience. .

On the other hand, when the detergent input unit is exposed to the outside (Comparative Example 1), the problem that the solid detergent is pulled out during the cleaning occurs, the usability is poor, and it is difficult to continuously generate and maintain the foam, the cleaning power compared to the embodiment Degraded. In addition, in the case of a washing pad made of a single layer of fiber fabric without a detergent inlet (Comparative Example 2), the drying speed was the fastest after washing, but the washing pad was remarkably thinner, so that the voids were insufficient and bubbles were generated. It is not abundant and, accordingly, the washing power is relatively poor.

Experimental Example 2: Evaluation of antibacterial performance of solid detergent 1 (E. coli)

In order to evaluate the bacterial growth inhibition performance by the solid detergent remaining after using the washing pad of the above embodiment, after the solid detergent was powdered, 1 g of powder was dissolved in 9 g of 3 ° DH hard water (JIS K3362) to prepare a 10 wt% solution. Prepared.

Meanwhile, a sample was prepared by inoculating E. coli (NBRC 3972) at a concentration of 0.3 wt% in broth medium of DIFCO Corporation. Here, the sample 1 and the sample 2 to which 0.5g of the solution was added were left at 25 ° C. for 18 hours, and the number of viable cells was measured three times, and the results are shown in Table 2 below.
