Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning article used for business or household use.

[0002]

2. Description of the Related Art Conventionally, as cleaning articles, there are vacuum cleaners, brooms, mops, rags, chemical rags, etc., which are properly used according to the purpose or advantages and disadvantages of each method. In recent years, the number of floors using wooden floor materials has increased in apartment houses and the cleaning methods have changed. Particularly, in an apartment house, a cleaning article that emits high noise such as a vacuum cleaner is disliked, and a cleaning article that can be easily and quietly cleaned is desired.
Mops originally serve these purposes,
Conventional mops have hygiene and functional issues. Conventional mops include a wet type in which a woven cloth such as a rag is fixed to a mop handle and wet with water, and a dry mop in which a chemical rag without water is used. With wet type mops that use rags, etc., bacteria spread on the rag, and using a rag that has grown bacteria causes hygienic problems such as increased contamination, and water is used. There are various problems (such as rough hands in winter). Also, even dry mops are replaced after a certain period of use, so mops are not washed or replaced for a long time.
Similarly unsanitary. Compared to such conventional products, the disposable type cleaning sheet, which can be attached to a patterned device and used like a mop, can be replaced easily with a new one when the sheet becomes dirty. It can be said that it is the most suitable as a cleaning article that can maintain a preferable hygiene condition, and that can be used easily, easily, quietly and hygienically without using water.

As a disposable type cleaning article or cleaning sheet to be mounted on a patterned device, many non-woven fabric-based materials have been proposed. Generally, a flat woven fabric or non-woven fabric impregnated with an oily substance is used, and when attached to a device with a handle, it is difficult to wipe off the hair on the floor or the pet's hair. , It was unsuitable to be used by attaching it to a patterned device. In addition, the heat-shrinkable sheet and the non-woven fabric are partially bonded so that larger dust is entangled and held, and the heat-shrinkable fibers are heat-shrinked to partially form convex portions (special feature). Kaihei 4-250130, Japanese Unexamined Patent Publication (Kokai) No. 4-31230, and a mixture of ultrafine fibers having a fineness of less than 0.8 denier (Japanese Unexamined Patent Publication No. 4-96724) have been devised, but partially convex due to heat shrinkage. A heat shrinking step is required to obtain the shaped portion, and it is difficult to manage the step so that the degree of heat shrinkage is constant.
Further, when using ultrafine fibers, there is a problem that the strength of the sheet is reduced.

[0004]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is that it has sufficient strength to be attached to a handle device to clean the floor, is hygienic, and falls on the floor. Provide a cleaning article that can easily and effectively capture hairs, pet hairs, and fine dust that are present, and that have a good texture even if they are held by hand without being attached to a patterned device. That is.

[0005]

The cleaning article of the present invention comprises:
A non-woven fabric laminate comprising two or more layers of non-woven fabric aggregates formed by the entanglement of fibers of a fibrous web composed of 1 to 5 denier fibers, the surface of each layer of the laminate coming into contact with each other. To one or both of them, an adhesive made of a thermoplastic resin is discharged and applied in a fibrous or granular form by utilizing a heated air flow by a heating and melting spray device, and then,
The above object is achieved by laminating each layer of the laminate.

In the cleaning article according to claim 1, as the non-woven fiber assembly which is a constituent unit, a non-woven fiber assembly formed by entanglement of fibers of a fiber web composed of fibers of 1 to 5 denier is used. This fiber assembly is used as a laminate of two or more layers, and is made of a thermoplastic resin on one or both of the abutting surfaces of each layer by using a heated air flow by a heating and melting spray device. The agent is applied in a fibrous or granular form by spraying, and the layers are laminated together.

In the cleaning article according to the present invention, at least one layer of the laminate has a non-woven fiber assembly formed by entanglement of fibers of a fibrous web having 1 to 5 denier fibers, and a mesh sheet. Or, by using a layer of coarse woven fabric, add strength and reduce the amount of adhesive,
It is possible to variously change the entangled state of the non-woven fiber aggregate.

In the cleaning article according to the third aspect, the total amount of the adhesive applied to the adhesive surface is 1 to 30% by weight based on the total weight of the fibers of the nonwoven fabric laminate.

In the cleaning article according to the fourth aspect, the application area of the adhesive applied to the adhesive surface is 1 to 30% of the adhesive surface.

In the cleaning article according to the fifth aspect, in order to improve the trapping performance for the fine dust on the sheet, 0.1 to 1 is used.
It is impregnated with 5% of the drug.

[0011]

The cleaning article of the present invention has a specific, namely 1 to
A non-woven fabric laminate comprising two or more non-woven fabric fiber aggregates formed by entanglement of fibers of a fibrous web of 5 denier fibers, which is one of the surfaces of the laminate in contact with each other. One or both of which is characterized in that an adhesive made of a thermoplastic resin is discharged and applied in a fibrous or granular form by utilizing a heated air flow by a heating and melting spray device, and each layer of the laminate is laminated. The laminated body having sufficient strength, softness, and moderately fluffed, is sufficient to be attached to a patterned device and used for cleaning the floor. It is strong and easily and effectively captures hair, pet hair, and fine dust. Further, the cleaning article has a good texture even if it is held in a hand and used without being attached to a handle with a handle. On the other hand, if the fineness of the fibers of the non-woven fiber assembly used is less than 1 denier, sufficient strength cannot be obtained, and if it is greater than 5 denier,
Capture performance is reduced. In the cleaning article of the present invention, a thermoplastic resin is adhered to the contact surface of each layer of the non-woven fiber assembly formed by the entanglement of the fibers of the fiber web of 1 to 5 denier fibers. The agent is applied in a fibrous or granular form by spraying to bond the layers. Therefore, as in the case where the adhesive is applied to the entire surface, a layer is formed by the adhesive and each layer of the fiber assembly is not separated by the adhesive layer, and thus the nonwoven fabric laminate of the present invention is It is possible to capture dust as a unit. Further, by applying the adhesive in a fibrous or granular form, the surface to be bonded can be efficiently bonded with a smaller amount than the entire surface application, and the texture becomes soft.
The adhesive used here is not particularly limited as long as it can bond the fibers to be adhered, but a rubber-based, olefin-based, EVA-based hot-melt adhesive is preferably used. . The fibers used in the fiber assembly include thermoplastic fibers such as polyester-based, polyamide-based, and polyolefin-based fibers, or composite fibers thereof, semi-synthetic fibers such as acetate, recycled fibers such as cupra and rayon, or cotton and kenaf. Any of the above natural fibers may be used, or mixed fibers thereof or the above fibers obtained by mixing split fibers to the extent that strength is not a problem may be used.

[0012] At least one layer of the non-woven fabric laminate as the cleaning article of the present invention is a net-like sheet or mesh in a non-woven fabric aggregate formed by entanglement of fibers of a fibrous web of 1 to 5 denier fibers. Adds strength, reduces the amount of adhesive, and changes the entangled state of the non-woven fiber aggregate formed by the entanglement of the fibers of the fibrous web by using a stack of coarse fabrics Is also possible. Examples of the reticulated sheet used here include those obtained by substantially uniformly widening and opening the tow of continuous filaments, a net made of polymer filaments, or a perforated film or nonwoven fabric having certain pores. As open-woven fabric,
Examples include gauze and ginseng. When using a reticulated sheet, the mesh of the reticulated sheet, wire diameter, line distance, hole diameter, hole pitch, hole pattern, etc., or the type and thickness of fibers when using a coarse mesh fabric, the number of fibers per unit width Etc. need to be determined in consideration of the adhesive force that is determined by the type of adhesive used, the area and amount applied, and the type of fiber used. As a method for laminating a mesh sheet or a coarse woven fabric on a nonwoven fabric-like fiber assembly, it may be simply laminated, but may be laminated at the same time when the respective fiber assembly layers are bonded, or may be preliminarily meshed. The sheet or coarse woven fabric and the nonwoven fabric-like fiber aggregate may be heat-fused or may be bonded together by using an adhesive.

In the cleaning article of the present invention, when the total amount of the adhesive applied to the adhesive surface is 1 to 30% by weight of the total fiber weight of the nonwoven fabric laminate, the texture is more excellent and economical. It will also be advantageous.

In the cleaning article of the present invention, when the area of application of the adhesive applied to the adhesive surface is 1 to 30% of the adhesive surface, the texture is further excellent and it is more economically advantageous. It will be
