Description

The cleaning pad {A PAD FOR CLEANING}

The present invention relates to a cleaning pad which is convenient to use and has excellent cleaning power and antibacterial property.

Various types of contamination can be somewhat clean with water alone, but in most cases the use of detergents is required to remove contamination. Detergents are generally divided into soaps and synthetic detergents. The soap is the oldest detergent, made by boiling mixed oil of animal and plant and sodium hydroxide, and the synthetic detergent is made by mixing various additives with the surfactant made from the petroleum compound raw material.

The surfactant, which is a main component of the soap and the synthetic detergent, contains both a lipophilic group and a hydrophilic group in the molecule and plays an important role in removing contaminants. Specifically, when the detergent penetrates between the washing water and the contaminant, the hydrophilic group of the molecule of the surfactant is adsorbed and arranged while being directed toward the water and the oil oil toward the contaminant, weakening the binding force between the washing water and the contaminant, To be able to become. In addition, contaminants can be easily removed by applying a physical force to the wash.

However, when the detergent is used excessively, various problems may occur. In particular, in the case of a kitchen detergent for washing dishes, since the user touches the user's skin directly, the user is continuously exposed to the hands and nails, And the like. In addition, in the case of remaining in a tableware, such detergent components may be directly administered to the user's oral organs to adversely affect health and hygiene.

In general, kitchen detergents are used as a liquid type. Such liquid type is not easy to carry and store because of its heavy weight and heavy weight, and it is difficult to control the amount when it is used, so that it can be used more than necessary. Accordingly, although a solid type kitchen detergent has been developed, in the case of a solid type, since it is exposed to the external environment until it is consumed after its use, the propagation of germs may be facilitated and sanitary control may be difficult. Also, as the size of the solid type kitchen detergent is reduced according to use, the user may feel inconvenience in bubbling.

Therefore, it is desired to develop a cleaning pad which is capable of hygienic management of a solid type kitchen detergent and has excellent usability and cleaning ability.

The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a structure of a cleaning pad having excellent usability and antibacterial property, will be.

According to an aspect of the present invention, there is provided a cleaning pad having a hollow space formed therein, the cleaning pad comprising: a detergent dispensing part formed at one end of the cleaning pad; And a seal portion extending from both ends of the detergent dispensing portion to seal the other end of the cleaning pad, wherein the detergent dispensing portion has a structure in which the detergent dispensing portion is folded and fixed from the outside to the inside of the cleaning pad, to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "indirectly connected" . Also, when an element is referred to as "comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

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

1 is a schematic view of a 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 formed therein; A detergent dispensing part 20 formed at one end of the cleaning pad 10 and a sealing part 30 extending from both ends of the detergent dispensing part 20 to seal the other end of the cleaning pad 10; .

The cleaning pad 10 may be applied to a cleaning material, that is, a tableware, and rubbed or rubbed to remove contaminants. The cleaning pad 10 may be formed by folding and sewing a single fiber fabric. The fabric can be folded or overlaid to sew the edges of the fabric. At this time, it is preferable to sew the fabric except for the detergent input portion 20. The sewing can be performed by a sewing machine or a sewing machine, but is not limited thereto.

In addition, the cleaning pad 10 may include a contact portion of 5 to 15 mm. As used herein, the term " stitching " refers to the width from the sewing line to the end of the fabric. The contact portion may be located outside or inside the cleaning pad 10, but when the contact portion is located outside the cleaning pad 10, the user may be able to irritate the user's skin during the cleaning process, I can feel it. Therefore, when the usability and aesthetics of the cleaning pad 10 are considered, it is preferable that the contacting portion is arranged inside the cleaning pad 10.

In addition, it is preferable to cut the fiber cloth in consideration of a portion to be used as a contact portion when cutting the fiber cloth. Although the cutting standard is not specified, it may be designed in the range of 200-300 mm in width and 70-130 mm in length based on the fiber fabric in consideration of user convenience, portability and storage.

FIG. 2 is a schematic view of an integral structure of a textile fabric according to an embodiment of the present invention. 2, the textile fabric comprises an outer layer 11 comprising a plurality of voids and an inner layer 12 interposed between the outer layers 11 and the outer layer 11 is provided on the inner layer 12 And can have an integral structure. Specifically, it may include an outer layer 11 that is parallel to each other and an inner layer 12 that is interposed between the outer layers 11.

The yarns of the inner layer 12 interconnecting the outer layers 11 may be irregularly arranged in a loose structure so that spaces or voids may be formed between the yarns and solid detergent may be injected into the voids, . Also, since the two outer layers 11 have a three-dimensional structure connected by the inner layer 12 even though they are woven into a single layer, durability and cleaning power can be improved by providing the same cushioning feeling as when the three or more layers are laminated.

A textile fabric of this structure can be woven by a lacquer machine. As the knitting machine of the warp knitting fabric, the lacquer machine uses yarn or filament yarn of various kinds of natural or artificial fibers as a knitting yarn, and weaves the fabric by combining other knitting structures on the basis of chain weaving. A warp knitted fabric is a fabric that is fed from the longitudinal direction to make a loop in the longitudinal direction.

The general weaving sequence of the warp knitted fabric is that the crochet with the various lace is inserted into the front loop, the new yarn is hooked on the crochet, and the yarn is taken out into the loop to make a new loop. When this process is repeated, chain stitch, Chain knit organization and this is the basic organization of warp knit fabrics. However, since the fabric can not be formed only by the basic structure, when the guide for supplying the knitting yarn is alternately shifted to the left and right when the new loop is made, the loops of the left and right are connected to each other so that the fabric can be woven.

The lacquer should be wound around a laselege by winding a knitting yarn to be supplied to a guide or a guide needle for supplying a knitting needle and a knitting yarn at the time of weaving, and the number and the needle of the beam and the guide need to be varied depending on the type of tissue of the warp knitting fabric Do. When the needle bed is one row, it is called one-row needle bed or single needle bed. The lacquer group in the monoclinic form is called a single raschel and the lacquer in a double row form is called a double raschel.

Since the fiber fabric has a three-dimensional structure in which the two outer layers 11 are mutually connected by the inner layer 12 interposed therebetween, it is preferable that the fabric is woven in a double lathing machine having two rows of needles rather than a single lacquer of one row .

In addition, the outer layer 11 may have a net-like structure. In general, since the cleaning pad serves to remove contaminants during washing, there is a risk that the contaminants may remain after the washing, resulting in the propagation of bacteria. Furthermore, washing dishes with bacteria-repellent cleaning pads can increase the rate of bacterial infections, and can have a catastrophic effect, especially on low-immunity users such as the elderly and children. The outer layer 11 of the net structure, that is, the cleaning pad 10 according to the present invention, can be dried quickly after washing, thereby preventing the propagation of germs and facilitating hygienic management.

On the other hand, the fiber fabric may be selected from the group consisting of polyester yarn, polypropylene yarn, polyethylene yarn, low density polyethylene yarn, high-density polyethylene yarn and mixed yarn of at least two of them.

The above-mentioned polyester is a resin having excellent productivity. The fabric produced by using the polyester is excellent in durability, and is resistant to insects, fungi, etc., and is easily stored for a long time. In addition, because of high atomic bonding force, water absorption rate is low, and it is possible to dry in a short time even when wetted with water.

The polypropylene is widely used in producing fabrics together with polyester. Particularly, the polypropylene fabric is superior in light weight to the fabric structure compared to the polyester fabric, and is excellent in wearing comfort, and can always maintain a comfortable state due to the sweat absorbing sweat generated from the human body and sweating out. In addition, it has excellent thermal insulating properties due to low thermal conductivity, and has a moisture content close to '0', which is excellent in antibacterial property.

The polyethylene is a thermoplastic resin having excellent electrical insulating properties, quality and water resistance, low cost and easy processing, and is widely used in everyday household goods.

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

Generally, yarns are generally produced by spinning a molten resin composition and then stretching. The spinning process refers to melting a polymer material capable of making fibers and drawing the yarn through fine holes. Since the fibers immediately after the spinning process have uneven molecular arrangement and weak strength, they can be stretched and the strength of the fibers can be improved by adjusting the directionality of the fibers.

Therefore, a yarn to be manufactured can be selected as a subject resin, and the yarn can be produced through melting, spinning, and stretching processes. In addition, the yarn used in the production of the fiber fabric may be a single yarn or a mixed yarn in consideration of physical properties, costs, and effects to be realized by the final product.

The thickness of the yarn may be 300 to 800 denier. If the thickness of the yarn is less than 300 deniers, the clearance of the fabric becomes small, the generation of detergent foam is not sufficient, and the detergency may deteriorate. If the yarn density exceeds 800 denier, May be deteriorated.

As used herein, the term " denier " is a unit of international standard used for indicating the thickness of long filaments, such as silk, in synthetic fibers, regenerated fibers, or natural fibers. When the length of the yarn is 9,000 m, 1 g, it is defined as 1 denier. For example, a 10 denier has a length of 9000 m, a yarn weight of 10 g, a 100 denier, a length of 9000 m, and a yarn weight of 100 g. The larger the denier value, the thicker the yarn, and the smaller the denier, the smaller the yarn.

The thickness of the fiber fabric may be 5 to 10 mm. If the thickness of the fiber fabric is less than 5 mm, the amount of the solid detergent to be injected may be reduced to deteriorate the detergency. If the thickness is more than 10 mm, the deterioration of the usability may occur.

The porosity of the fabric may range from 10 to 30% by volume. If the porosity of the fiber fabric is less than 10% by volume, the amount of the solid detergent to be injected may be reduced to deteriorate the detergency. If the porosity is more than 30% by volume, the durability of the cleaning pad may deteriorate.

Meanwhile, the cleaning pad 10 may have a hollow space therein, and the solid detergent may be introduced into the cleaning pad 10 through the detergent input unit 20. If a solid detergent is provided in the inside of the cleaning pad 10, bubbles can be continuously generated, so that convenience of the user during cleaning can be improved and there is no need to provide a separate detergent storage or storage space, The environment can be kept clean.

If the length of the detergent dispenser 20 is less than 35 mm, it may be difficult to insert the solid detergent. If the length of the detergent dispenser 20 is more than 45 mm, the detergent dispenser 20 May be longer than necessary and the usability may be deteriorated.

The size of the solid detergent can be adjusted to a range that can pass through the detergent input unit 20, and its shape is not limited, but it can be manufactured in accordance with the preference of the user in circular, oval, square or the like. In addition, the solid detergent adjusted to the above range can be washed three to four times, so that it is easy to carry and store, and the time for exposure to the outside is shortened, so that sanitary control of the solid detergent can be facilitated.

Particularly, the solid detergent remaining in the interior of the cleaning pad 10 after use can suppress the bacterial growth of the cleaning pad 10.

Specifically, in the case of a general cleaning pad, the water remains in the state of being used after being used, and bacteria can easily reproduce when the food is not removed on the cleaning pad. On the other hand, the cleaning pad according to an embodiment of the present invention can inhibit the growth of bacteria because the solid detergent remains in the empty space inside thereof after use. In addition, since the solid detergent is 3 to 4 times as described above, the washing pad can continuously provide an effect of inhibiting the growth of bacteria.

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 the health of the user. The above-mentioned natural detergent is produced by adding a synthetic material such as an artificial fragrance or a preservative to a natural material as a theme. However, it has an advantage of being environment friendly and protecting the user's skin. The synthetic detergent uses an additive that is not decomposed in a natural state, such as a petroleum chemical surfactant and a phosphate, and is excellent in cleaning power, but may cause environmental pollution and skin diseases of the user.

3 is a cross-sectional view of a cleaning pad having a detergent dispensing portion according to an embodiment of the present invention. 3, the detergent dispenser 20 may be folded and fixed from the outside of the cleaning pad 10 toward the inside thereof. If the detergent dosing unit 20 is exposed to the outside, the solid detergent can be easily input, but the detergent can easily escape during use and the usability may deteriorate. Therefore, the detergent dosing unit 20 is folded inwardly, preferably triangularly, from the outside of the cleaning pad 10, and the detergent dosing unit 20 ) Is sewn and fixed.

Accordingly, as shown in FIG. 3, since the detergent dispenser 20 is formed inside the cleaning pad 10, it is easy to insert the solid detergent into the cleaning pad, So that the user can conveniently clean the tableware even during cleaning.

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

Example

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

The edge of the fabric was sewn with a sewing machine except for the 40 mm of the portion where the fabric was cut to a width of 260 mm and a length of 90 mm and the side was folded in half to make the detergent input portion. . The detergent input part 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 edge of the detergent input part was sewn and fixed to prepare a cleaning pad.

Comparative Example  One

A cleaning pad was prepared in the same manner as in Example 1 except that the detergent input portion was formed outside the cleaning pad.

Comparative Example  2

A single-ply cleaning pad was prepared which was not sewn to the fabric and the detergent input was not separately formed.

(Relative Evaluation Criteria: Excellent, Good, Fair, and Poor)

Referring to Table 1, it was found that the cleaning pad made by folding and fixing the detergent injection part from the outside to the inside (Examples) was excellent in all performance evaluations (washing power, usability, hygiene, foam generation). Particularly, since the solid detergent is provided in the inside of the cleaning pad, it is expected that the foam will be abundantly generated and retained, so that the detergent is excellent and the solid detergent does not escape so that the user can wash the tableware without inconvenience .

On the contrary, when the detergent input portion was exposed to the outside (Comparative Example 1), there was a problem that the solid detergent escaped during washing, resulting in poor usability, and it was difficult to generate and maintain the foam constantly. . In addition, in the case of a cleaning pad made of a single-ply fabric without a detergent input portion (Comparative Example 2), the drying speed was the fastest after the cleaning, but the cleaning pad was significantly thinned, So that the cleaning power was relatively poor.
