Description

Support for cleaning the human body {Supporter for cleaning the human body}

The present invention relates to a scrubbing support for a human body, and more particularly, a single use of the scrubbing agent or detergent in a dry state or wet form after the deposition or the use of the scaffold repeatedly without the deposition of the cleansing agent, or every time it is used. It relates to a cleaning support that can be used repeatedly by adding a cleaning agent.

Typically, human cleansers have been marketed in various forms such as soaps, cleansing foams, body cleansers, shampoos, cleansing creams, cleansing lotions or cleansing gels. Such cleaning products have been developed to satisfy a certain degree of satisfaction according to the user's use and purpose, and such criteria include excellent cleaning effect, hypoallergenicity, freshness, skin feel, foaming, and odor. The ideal human cleanser does not dry out the skin daily, does not irritate the skin or hair, should be refreshed, and the skin should remain soft after use. However, in many cases, it is very difficult to clean a normal detergent completely according to the type of human pollutant, that is, sebum, dead skin, general pollution, and the like.

In particular, when makeup is made for personal production, it is difficult to completely remove contaminants of powders and waxes, which are the main ingredients of makeup products. That is, in order to remove the waste of a face, the face wash cream is mainly used, or the dry type or wet type, such as disposable cleaning tissue or nonwoven fabric on the sheet | seat containing moisture or soapy water, is used. In the case of cleansing cream, since the cream is rubbed with a finger, the washing effect is relatively insignificant, and the cleansing work is also inconvenient. In addition, in the case of a sheet of paper and non-woven fabric pads containing moisture or soapy water, such as mold or bacteria due to the moisture content there is a risk of storage inconvenience to be kept sealed.

Therefore, in order to remove fine powder or wax in the pores without skin irritation, and to improve the cleaning ability of the cleaner for the human body such as the body or the foot, it is necessary to remove the pollutants in the pores in addition to the cleaning products. There is a need for the development of cleaning aids.

To this end, various forms of cloths that can be used as a scrubbing support for human body have been presented. That is, conventional towels, bath towels, puffs, sponges, and the like have been proposed and used as a scrubbing body for human body. It is not designed to achieve the purpose of removing it more effectively. In addition, the bath towels have a disadvantage that the damage to the skin may occur when the excessive roughness due to excessive pressure.

In order to solve this problem, Korean Laid-Open Patent No. 2001-23946 is a multi-layer cloths type product in which a cleaner is deposited and dried to produce a multi-layer by adhering a pulp-based layer and a mixed layer of rayon and polyester with a water-soluble adhesive. One cleaning support has been disclosed. This suggests that when the support is wetted with water, the pulp layer is wrinkled due to the difference in the elongation of the two layers, and the usability of the two layers is differentiated. However, such bilayer formulations have already been used in US Pat. No. 4,948,585 to laminate polyurethane and non-woven paper, so there is no specificity for the dual structure.

In order to solve the above problems and apply the cleaning product to the human body more efficiently, the present inventors have studied to develop a cleaning support for removing contaminants, sebum, secretions, etc. of the skin, and the present inventors are superior to the conventional cleaning support. It was possible to develop a cleaning support having a function of removing pollutants. That is, a single layer cleaning support prepared by varying the content, basis weight, and production form of the composition, or a multi-layer cleaning paper prepared by laminating the two or more surfaces having different properties by thermal bonding. When the amorphous microfiber cleaning support prepared by treating the composition by the nonwoven fabric manufacturing method is used, various contaminants of the skin can be cleanly removed and the present invention has been completed.

Accordingly, an object of the present invention is to provide a single layer cleaning support prepared by varying the content of content, basis weight, and production form, or a multilayer support for cleaning produced by laminating two or more surfaces of different properties. To provide.

Another object of the present invention is to provide a cleaning support prepared in an amorphous microfiber formulation by treating the composition with a nonwoven fabric manufacturing method.

Another object of the present invention is to use a dry formulation or wet formulation in which a cleaning component or detergent is deposited and dried, or a detergent for each use, in order to remove contaminants or dead skin cells of the skin using the cleaning support. The present invention provides a cleaning support that can be used repeatedly with or without a cleaning agent.

1 is a view showing a cross section of a cleaning support prepared by laminating three layers of different properties in the cleaning support according to the present invention.

Figure 2 is a view showing a cross-section of the cleaning support of the microfiber formulation according to the present invention.

In order to achieve the above object, the present invention provides a single layer of cleaning support prepared by varying the content, basis weight and form of the composition, or by laminating by heat bonding two or more surfaces of different characteristics It is characterized in that it provides an amorphous microfiber cleaning support prepared by treating the prepared multi-layer cleaning base member or composition by a nonwoven fabric manufacturing method.

Hereinafter, the configuration of the present invention in more detail.

First, in the present invention, a single layer of a cleaning support prepared by varying the content of the composition, basis weight and manufacturing form, or two or more surfaces of different characteristics, prepared by laminating by thermal bonding. It is characterized by providing a cleaning paper body.

As the composition of the cleaning support, that is, the component, polypropylene, polyester, wood pulp, mulberry pulp, rayon, polyvinylacetate, cellulose, nylon, polyolefin, polyethylene, polyurethane, cotton, etc. may be used. have. The components are prepared in a fibrous form by vertically and horizontally spinning alone, or by mixing two or more of the above components in a ratio suitable for use as a cleaning support in consideration of the surface state of the support and the purpose of use. The cleaning support can be manufactured.

Examples of the preferred cleaning support are as follows.

In the case of a mixed support comprising a mixed component of polyester and rayon as a composition, the ratio of polyester to rayon is 10 to 50:50 to 90, for example, 10:90, 20:80, 30:70, and 40:60. After mixing the polyester and rayon in a ratio of 50:50, filaments are uniformly arranged, and then sprayed with a high pressure steam water jet to prepare a fibrous polyester and rayon mixed support. At this time, it is preferable to make a basis weight about 40-90 gr / m <2>. In processing, the fibrous structure may be used in the form of a plate or in the form of a hole.

In the case where the composition is polypropylene, it is preferable to melt the polypropylene at 230 to 250 ° C., and then spin it vertically to smooth the sheet to have a basis weight of 10 to 25 gr / m 2, and to use it as a cleaning support. In processing, the fibrous structure can be used in the form of flat plates or holes.

In the case of a mixed support composed of a mixture of polyethylene and rayon as a composition, there may be a difference in processability depending on the form, namely, plate type or hole type. It is soft. The most preferred form is the hole type, since the hole type can increase the softness and reduce the stiffness when used by depositing the cleaner. Preferred compositions of the hole-type cleaning support are mixed components of polyethylene and rayon, mixed components of rayon and pulp, mixed components of rayon and polypropylene, mixed components of cotton and polyester, mixed components of cotton and pulp Etc. can be mentioned.

It is also possible to use the cleaning support as a single layer, but may be used as a cleaning support for multiple layers by laminating two or three layers (see FIG. 1). In this case, by laminating a support having different types and feelings, the front face and the back face may have different feelings, and thus they may be selectively used according to the type of human body cleaning site or pollutant. In the double or triple laminating method, the primary fabric is preheated at 85 to 95 ° C., preferably at 90 ° C. during heat bonding, and then two or three layers are heated at a temperature of 110 to 140 ° C., preferably 125 ° C. It is preferable to follow the method of pressing and bonding with a roller while maintaining the pressure condition at 70-100 PSI, preferably 80 PSI. Each surface to be subjected to laminating may have different properties depending on the type, content, basis weight, etc. of the composition, and also the adhesive strength, surface roughness, etc. of double or triple lamination may vary depending on the temperature, pressure, and embossing form of the lamination. Can be. This method of thermal bonding has the advantage of minimizing the irritation of foreign substances on the skin because the process is simpler and does not use an adhesive which is not friendly to the skin as a chemical component compared to the conventional support method using a water-soluble adhesive.

Referring to the support for washing human body according to the present invention in more detail as follows. Fibrous cloths are prepared by spraying polypropylene to a basis weight of 15 to 20 gr / m 2 by horizontal spinning. Next, the polyester: rayon was mixed at a ratio of 20:80, 30:70, and 40:60, respectively, and the mixed filaments were made into hole-type cloths having a basis weight of 50 to 70 gr / m 2, The two surfaces are laminated through thermal bonding. At this time, embossed dots are formed on the polypropylene surface. The size of the dot is preferably formed so that the diameter is 0.5 to 2 mm. It may be manufactured in a double structure as described above, but may be manufactured in a triple structure by further laminating an optional layer between the two layers. The layer that can be added at this time may be used by appropriately selecting a fibrous layer well known in the art.

After the cleaning component or the detergent is deposited on the cleaning support prepared through the composition and processing method as described above, it may be used as a disposable support after being manufactured as a wet type or as a dry type after drying. In this case, it is possible to perform a different function according to the production form of the single composition cloths, single hole type cloths, or double type cloths. That is, when the composition is polypropylene fiber, adsorption to fat-soluble contaminants such as wax component in sebum or makeup residues is possible, and when the composition is polyester + rayon or cotton, adsorption to water-soluble contaminants is possible. When laminating the adsorptive side to fat-soluble contaminants such as fiber and polyester + rayon or polypropylene fiber and cotton, and the side which is adsorbable to water-soluble contaminants, both oil-based or water-soluble contaminants It can be removed easily and effectively. That is, in the case of using dual type cloths having different properties, there is an advantage that the selective application according to the characteristics of the contaminants is possible.

Korean Laid-Open Patent Publication No. 2001-23946 discloses a scrubbing support for adjusting roughness by making holes in pulp fibers, which is a form in which two layers are laminated using a water-soluble adhesive. However, the scrubbing support for the human body according to the present invention is manufactured in a double structure form through two materials each having a different roughness, and the embossing dot treatment of one of the two surfaces gave a difference in feeling of use. By introducing a hole shape to increase the supply rate of the cleaning component and the cleaning agent to increase the rate of foam generation and to improve the elasticity to improve the cleaning function for the skin formed with bending.

In the method of depositing the cleaning component or the cleaning agent on the cleaning support according to the present invention, it is preferable to use the method of depositing the cleaning agent constantly while the support is buried in the primary roller and then the support proceeds between the primary roller and the secondary roller. It is not limited to this. This method is similar to the method in which a normal gravure printing machine loads ink. It is also possible to prepare a wet formulation in which a detergent is deposited and use it as a disposable cleaning support. Alternatively, the support in which the detergent is deposited may be prepared in a dry formulation dried at a low temperature hot air of about 50 to 80 ° C. Dry formulations are used when wet with water and wet formulations are used as is. At this time, the washing | cleaning component or washing | cleaning agent which can be used can be used selecting arbitrarily what is normally used.

Secondly, the present invention provides a scrubbing support for microfiber formulations that can be repeatedly used by moistening in water without deposition of a detergent and then washing itself or selectively infiltrating a predetermined amount of a desired amount with a desired amount. It is characterized by. The cleaning support of the microfiber formulation according to the present invention is manufactured by dispersing the microfiber filaments in a solvent and spraying them with high pressure water vapor and irregularly arranging the filaments irregularly, in a manner similar to the nonwoven fabric production process. It is manufactured. The microfiber thus prepared has a thickness of 50 to 100 gr / m 2 and has a thickness suitable for use as a support for cleaning.

As a material for constituting the cleaning support for the microfiber formulation according to the present invention, nylon, polyester, polypropylene, or the like may be used alone or in combination of two or more thereof, and the ratio may be arbitrarily selected according to the use. In the case of the washing support, for example, when mixing nylon and polyester, it is appropriate to mix 30 to 40 parts by weight of nylon and 60 to 70 parts by weight of polyester. This is processed to form a microfiber filament, and then sprayed on a cylindrical roller on a solvent to produce a nonwoven fabric in which the microfiber filaments are irregularly arranged. In this case, the basis weight is less than that of the woven microfiber cloth, and it is preferable that the basis weight is about 50 to 80 gr / m 2.

Preferred scrubbing support of the microfiber formulation according to the present invention is a mixture of polyester: nylon at a ratio of 40 to 100: 0 to 60 and filament sprayed according to a nonwoven fabric manufacturing method to prepare an amorphous form (see FIG. 2).

In the case of microfiber fibers composed of a mixture of polyester and nylon, hair towels, face wash towels, and body towels have been commercialized as cleaning aids, but the filament arrangement of the microfibers is uniform and the skin is twisted and woven. While the filament friction is not easy to the fine bone of the surface stratum corneum, the microfiber nonwoven fabric of the present invention, the microfiber filament manufactured according to the nonwoven fabric method of the filament is amorphous, so even the fine part of the skin surface stratum corneum support Friction with can be achieved to achieve a smooth cleaning effect. Moreover, when using together with a detergent, the outstanding effect can be expected.

The cleaning support of the microfiber formulation according to the present invention is a support that is specially processed with ultra-fine fibers instead of conventionally used woven fibers, and has a feature that can gently penetrate between fine bones of the stratum corneum of the skin surface to remove contaminants. . In other words, the microfiber of the present invention is a fine filament of about 1/100 of the thickness of the human hair, that is, about 1 μm in diameter, has better absorption and drainage power than ordinary fibers, and has excellent ability to remove contaminants to clean the skin without irritation to the skin. It has a softening effect. This can be infiltrated with water to remove some water and then wiped like a massage on human skin to remove old dead skin, makeup residue, or sebum, and when used with cleaning products, it can effectively remove contaminants from the human body. There is a characteristic.

The microfiber cleaning support according to the present invention may be repeatedly used after simply adding water only every time without using a cleaning component or a cleaning agent, and may be optionally used by repeatedly adding a cleaning component or a cleaning agent.

Hereinafter, the configuration of the present invention will be described in more detail with reference to Examples and Test Examples, but the scope of the present invention is not limited thereto.
