Description

 Disposable scrubbing pad  

Embodiments discussed herein relate to disposable scrub pads. More specifically, embodiments of the present disclosure are directed to disposable scrubbing pads for single use purposes.

Typically, scrub pads are widely used to remove contaminants from tableware and the like. Typically, scrubbing pads are manufactured to have a degree of durability for reuse, so that once they are purchased by a consumer, they are typically continuously reusable. However, since conventional scrubbing pads are reused, contaminants may remain on their surface, rendering them contaminated or exposed to moisture, and thus may spread bacteria. Nonetheless, a separate sterilization procedure is not used when using the scrubbing pad.

The purpose of the present disclosure is to provide a disposable scrubbing pad that is manufactured to be discarded by the consumer after being used once, as compared to conventional scrubbing pads.

It is also an object of the present disclosure to provide a disposable scrubbing pad having the same cleaning power as conventional scrubbing pads, even if it is manufactured for disposable use.

According to one aspect of the present disclosure, a disposable scrubbing pad comprising a substrate comprising a fiber yarn melted in a web form and a core coating coated on the core surface can be provided. The fiber yarn includes a core made of synthetic resin. The core has a thickness of 3 denier or greater and 6 denier or less.

According to an exemplary embodiment of the present disclosure, the present disclosure has an effect of reducing manufacturing cost without deteriorating cleaning power as compared with the conventional scrubbing pad. Because it is difficult to reuse after one use, it can be discarded after being used once without any problem.

The illustrated embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It is to be understood that other embodiments may be utilized and may be constructed or modified without departing from the scope of the invention.

Specific embodiments for implementing the spirit of the present disclosure will be described in detail herein with reference to the drawings.

Detailed descriptions of well-known configurations or functions will be omitted herein when it is determined that the subject matter of the present disclosure may be unclear.

The terminology used herein is for the purpose of the description A singular expression can include a plural expression unless it is specifically indicated otherwise in the context.

Referring to Figures 1 through 3, the disposable scrubbing pad 1 can include a substrate 10 comprising fiber yarns 100 that are melted in a web form. Herein, the mesh form refers to a form in which the fiber yarns 100 are fused together in a state in which they are not arranged with a specific directionality. Although FIGS. 2 and 3 show that the fiber yarn 100 is melted in the form of a mesh, which is not necessarily limited thereto, the fiber yarn 100 may be melted in a mesh form to form the substrate 10.

The substrate 10 can be in direct contact with the object to be cleaned so that the object can be cleaned. The fiber yarn 100 constituting the substrate 10 may include a core 110 made of a synthetic resin and a core coating 120 coated on at least a portion of the core 110.

Core 110 can have a thickness of 3 denier (De) or greater and 6 denier or less. In this context, Danny refers to the international unit of the thickness of the fiber yarn and the like, which means, for example, the weight (g) of the fiber yarn having a length of 9,000 meters. When the thickness of the core 110 is less than 3 denier, the fiber yarn 100 may be broken, making it difficult to manufacture the disposable scrubbing pad 1. In addition, when the thickness of the core 110 exceeds 6 denier, the thickness and basis weight of the disposable scrubbing pad 1 may be less pronounced than the thickness and basis weight of the conventional scrubbing pad. Here, the basis weight means the weight (g) of the disposable scrubbing pad 1 per unit area (sqm).

Additionally, core 110 can include at least one of, for example, polyester fibers, nylon fibers, and acrylic fibers. However, the spirit of the present disclosure is not limited thereto.

The core coating 120 can be coated on at least a portion of the core 110 to improve the durability of the substrate 10. In particular, the core coating 120 can act to securely secure the adhesive of adjacent fiber yarns 100. Additionally, the core coating 120 can function as a filler that fills between adjacent fiber yarns 100. For example, the core coating layer 120 may be made of a coating solution for forming a core coating layer including a synthetic resin such as a latex resin, a phenol resin, a melamine resin, an acrylic resin, and the like. The coating solution for forming the core coating layer may be coated on the surface of the core 110 at a basis weight of 15 g/sqm or more and 60 g/sqm or less.

The durability of the substrate 10 can vary depending on the extent to which the core coating 120 is coated on the core 110. For example, the core coating 120 may be coated on at least a portion of the core 110 at a basis weight of 15 g/sqm or more and 60 g/sqm or less. When the core coating 120 is coated on the core 110 at a basis weight of less than 15 g/sqm, the extent to which the core coating 120 is coated on the core 110 may not be apparent. Moreover, when core coating 120 is coated on core 110 at a basis weight greater than 60 g/sqm, aggregation may occur between adjacent fiber yarns 100 by core coating 120.

As shown in FIG. 3, a supplemental coating 130 can be further formed on at least a portion of the fiber yarn 100. For example, the supplemental coating 130 may be coated on the core coating 120 on the surface side of the substrate 10. By supplementing the coating 130 thereby, the adjacent fiber yarns 100 can be more firmly fixed and filled between them to complement the bonding force between the adjacent fiber yarns 100. The make-up coating 130 may be contained in the substrate 10 at a basis weight of 130 g/sqm or more and 165 g/sqm or less.

For example, the supplementary coating 130 may be formed of a coating solution for forming a supplementary coating including a synthetic resin such as a latex resin, a phenol resin, a melamine resin, an acrylic resin, and the like. Further, the supplementary coating 130 may be formed by a spraying method in which a coating solution for forming a supplementary coating penetrates from the surface of the substrate 10 to at least a portion of the inner side of the substrate 10 to be coated on the core coating. At least a portion of 120.

As described above, the coating solution for forming the make-up coating can be applied to at least a portion of the fiber yarn 100 by a spraying method. The replenishing coating 130 may be formed with a small amount of coating solution by a spraying method, and a coating solution for forming a replenishing coating may be applied to the surface of the core coating layer 120 more densely.

Hereinafter, another embodiment according to the present disclosure will be described with reference to FIGS. 4 to 6. Referring to Figures 4-6, a disposable scrubbing pad 1 in accordance with another embodiment of the present disclosure can include a substrate 10 comprising fiber yarns that are melted in a web form in the same manner as one embodiment of the present disclosure. 100. As shown in FIG. 5, the substrate 10 can further include a friction material 140 to penetrate or coat over at least a portion of the fiber yarn 100. This embodiment differs from the previous embodiment in that it further includes a friction material 140 as compared to the previous embodiment. Therefore, the differences will be mainly described below, and the same description and reference symbols will be used.

The friction material 140 can improve the friction of the object to be cleaned. Friction material 140 can include minerals and the like. Further, the friction material 140 can be coated on at least a portion of the substrate 10 by a spray coating method. Specifically, the friction material 140 may penetrate from the surface of the substrate 10 to at least a portion of the inner side of the substrate 10. Further, the friction material 140 may be coated on at least a portion of the core coating layer 120 on the surface side of the substrate 10.

Since the friction material 140 is sprayed on at least a portion of the core coating 120 in this manner, the amount of friction material 140 required to increase the cleaning force can be reduced. Further, the friction material 140 may be applied to the surface of the core coating 120 more densely.

Additionally, the friction material 140 may be coated on at least a portion of the core coating 120 or may penetrate into the inner side of the core coating 120. Further, some of the friction material 140 may be coated while the remainder may penetrate to the core coating 120. In this case, the friction material 140 may be densely coated at a point where the fiber yarn 100 intersects or abuts the adjacent fiber yarn 100 and penetrates to the point. Since the friction material 140 is more concentrated at the point where the fiber yarns 100 intersect or abut, the bonding force between the fiber yarns 100 can be further improved.

Such a friction material 140 may be coated or penetrated into at least a portion of the fiber yarn 100 at a basis weight of 1.5 g/sqm or more and 2.0 g/sqm or less. In this case, when the friction material 140 is coated on the surface of the fiber yarn 100 with a basis weight of less than 1.5 g/sqm, the degree to which the friction material 140 is formed on the surface of the fiber yarn 100 may not be noticeable. Further, when the friction material 140 is coated on at least a portion of the fiber yarn 100 with a basis weight of more than 2.0 g/sqm, the friction material 140 may be excessively formed on the surface of the fiber yarn 100, and thus the object to be cleaned may be The friction material 140 is scratched, which may cause damage to the object to be cleaned.

Since the friction material 140 is coated on the surface of the fiber yarn 100 as described above, the friction between the substrate 10 and the object to be cleaned can be increased by the friction material 140, thereby improving the cleaning power of the disposable scrubbing pad 1.

As shown in FIG. 6, at least a portion of the fiber yarn 100 can further have a make-up coating 130. In this case, the friction material 140 may be formed by a spraying method such that the friction material 140 penetrates from the surface of the substrate 10 to at least a portion of the inner side of the substrate 10 to be coated on the surface side of the substrate 10. At least a portion of the coating 130 is replenished.

Further, the friction material 140 can be more densely coated at the point where the fiber yarn 100 intersects or abuts the adjacent fiber yarn 100 and penetrates to that point. Therefore, the bonding force between adjacent fiber yarns 100 can be reinforced by both the supplementary coating 130 and the friction coating 140.
