Conventional cleaners have been used to cut the knitted fabric or woven fabric to an appropriate size as it is, the cleaner of the woven material is often used throughout the day, because of the nature of the cleaner to maintain the wet state was a hotbed of various bacteria was unsanitary. Therefore, conventional knitted fabrics or fabric cleaners are randomly heated, sterilized, dried, used for disinfection, or used and disposed of once. This was very ineffective and not economical.

On the other hand, there is a wiping cloth using a non-woven fabric as a cleaner, which is usually a needle punching method for physically and mechanically bonding fiber aggregates on a web or sheet. It is made by cutting the nonwoven fabric manufactured by stitch bonding method or by spunlace method or thermal bonding method in which the fibers are bonded to each other by chemical means, that is, water or heat. The nonwoven cleaner was mainly used for one-time use and was not reusable after washing because the nonwoven cleaner was structurally in contact with water and easily deformed after washing.

Meanwhile, in Korean Patent Application No. 99-2431, which is pending by the present inventor, the edge of the laminate, in which a plurality of loops are formed by laminating at least one surface of a plurality of loops on both sides of a sponge containing an antimicrobial agent, is finished with an overlock stitch. Kitchen antibacterial cleaners have been announced, which are hygienic, have good odor removal ability, and are durable. However, the loop-like surface structure of the terry knitted fabric has a drawback that is easily detached and deformed by several times of use and washing.

Accordingly, an object of the present invention is to solve the drawbacks of the prior art by attaching the microfiber nonwoven fabric on both sides or one side of the sponge containing the antimicrobial agent in addition to the excellent cleaning and durability of the microfiber nonwoven fabric by the antimicrobial agent contained in the sponge The present invention provides a new residential antibacterial cleaner which is hygienic by enhancing antimicrobial properties, has an excellent effect on odor removal, etc., and also has greatly improved absorbency and durability.

It is to be understood that it is known enough to be commercially available to use.

The sponge 13 includes commercially available conventional antimicrobial agents, and this antimicrobial agent is to be understood as improving the hygiene state of the cleaner by preventing the growth of bacteria and the like, especially in the cleaner used always wet. As an antimicrobial agent that can be used in the present invention, the inorganic substance of the zeolite-based powder-substituted silver or the antimicrobial agent (Morton) of the United States (10,10'-oxy which is an antimicrobial component of Vinyzene) Commercially available antibacterial agents such as bistenoxine (10,10'-oxybisphenoxarsine) can be used, and the present invention is not limited by these antimicrobial agents.

The nonwoven fabric 11 is the same as or similar to a conventional nonwoven fabric, and is a fiber as heat using a spunlace nonwoven fabric or a thermoplastic fiber using a water jet method using natural fibers such as fine yarn or split microfiber rayon, cellulose, and the like. It is preferable to use a heat-bonded nonwoven fabric having strong interbonding, a needle punched nonwoven fabric mechanically bonded to each other, and particularly a spunlace nonwoven fabric.

In this case, it is most preferable to use nylon / polyester composite microfiber as a material of the spunlace nonwoven fabric.

The lamination and fixing of the nonwoven fabric 11 on the sponge 13 may be performed by forming an adhesive layer 12 by heating and pressing using an adhesive such as a common hot melt adhesive, and the hot melt adhesive used at this time And heating, pressure bonding process, etc. are all that can be easily understood by those skilled in the art. In addition, the lamination and fixing of the nonwoven fabric 11 on the sponge 13 may be performed by forming the adhesive layer 12 by fusion by partial melting of the sponge in addition to the bonding method, which is more preferable. The sponge to be used may preferably be a sponge made of thermoplastic polyurethane. Fusion by partial melting of the sponge can also be easily understood by those skilled in the art. In addition, the finishing of the edge of the residential antimicrobial cleaner according to the present invention, in which nonwoven fabrics are laminated on a sponge, a conventional overlock stitch 14 may be used, but a sealing method using ultrasonic waves is also possible, all of which are described above. Those skilled in the art can be applied as it is or modified to be easily understood.

For example, the overlock stitch 14 uses four threads (four strands) of the overthread, the lower thread, the first needle thread and the second needle thread to serve, and the first needle thread and the second needle thread are as in the prior art. The overlock stitch is performed in such a way that the overthread and the lower thread are held. At this time, the over yarn and the lower thread may be performed by forming the stitches of 18 times per inch using 300 s / 3 and all needle threads as in the conventional art.

Residential antibacterial cleaner according to the present invention having such a configuration is supported by a sponge because the non-woven fabric is substantially laminated and fixed on the sponge to have excellent shape stability and to maintain the original state even after washing. In addition, the nonwoven fabric is supported by a sponge having excellent hygroscopic form stability and form resilience, thereby improving the grip feeling of the residential antibacterial cleaner according to the present invention, that is, workability when working by hand.
