Abstract

PURPOSE:To exhibit excellent anti-bacterial effect even in a dust control mat for rental wherein washing is to be repeatedly performed and to exhibit the durable anti-bacterial effect without decomposing an anti-bacterial agent at temp. of molding. CONSTITUTION:A dust control mat 1 is constituted by providing a surface material with piles 3, a falling-out preventing material 4 attached on the rear face of this surface material and being responsible to prevention of falling-out of the piles and a backing material being integrally fixed with the surface material. An anti-bacterial ceramic is incorporated into one or the whole of the surface material, the falling-out preventing material and the backing material 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust control mat, and more particularly to a dust control mat having an antibacterial effect.

[0002]

2. Description of the Related Art A dust control mat removes dust and mud adhering to the bottom of footwear and the like, but the removed dust and the like remains on the carpet portion of the surface thereof.
Various miscellaneous bacteria that are carried along with dust tend to propagate.

Further, since the back side of the dust control mat is lined with synthetic rubber, synthetic resin, or a mixed material thereof, water or moisture stays between the back side and the floor of the dust control mat. It is easy, and mold grows and various bacteria propagate. In recent years, hospital infection caused by methicillin-resistant Staphylococcus aureus has become a big problem, and even in dust control mats for regular use or rental, a mat that continuously exhibits excellent antibacterial effect is realized. Is required.

Therefore, in order to suppress the growth of such germs and the like, conventionally, an antibacterial chemical solution is fixed on the surface of the pile yarn on the carpet surface in the manufacturing process of the pile yarn, or when the carpet is washed, the washing liquid is antibacterial. Add chemicals or germicides, attach antibacterial agents or germicides to the carpet,
The method of giving the effect was generally adopted.

[0005]

However, when the conventional method as described above is used, the antibacterial effect is not long-lasting, and especially in the case of a rental dust control mat for repeated cleaning, the antibacterial effect is not sustained. The improvement of the sex was desired. Further, conventional antibacterial agents are often used as organic substances, and they are often decomposed by the temperature (generally 130 ° C. or higher) when molding the dust control mat, and the antibacterial function is often lost.

Therefore, the present invention exhibits an excellent antibacterial effect even in a dust control mat for rental which needs to be repeatedly washed, and the antibacterial agent is not decomposed by the temperature during molding and the antibacterial agent is not decomposed. It is an object of the present invention to provide a dust control mat that can exert its effects continuously.

[0007]

A dust control mat according to the present invention is a surface material having a pile, an anti-pull-out material provided on the back surface of the surface material for preventing the pile from coming off, and an integral part of the surface material. And a backing material that is fixed to the backing material, and part or all of the surface material, the slip-out preventing material, and the backing material contain antibacterial ceramics.

[0008]

[Function] Since the antibacterial agent is not only attached to the surface of the material but also contained inside the material, the antibacterial agent does not separate due to friction or rubbing, so that the antibacterial function can be maintained continuously. Become.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 (a) and 1 (b) are schematic sectional views showing a part of the sectional structure of a dust control mat showing an embodiment of the present invention. In the figure, a dust control mat 1 is provided with a tufted carpet (surface material) formed by planting piles 3 on a base cloth (woven cloth or non-woven cloth) 2, and the back side of the tufted carpet is called a pile falling prevention material 4. It is backed with a backing material 5.

The pile 3 is formed into a cut pile as shown in FIG. 1 (a) or a loop pile as shown in FIG. 1 (b), and these piles 3 are polyesters mixed with antibacterial ceramics. (For example, a product name manufactured by Kuraray Co., Ltd. [Sanitor 30]) 65% and regular polyester 35% are used to form a mixed spinning No. 8 twin yarn (product name [Spell bar set]). The pile 3 is dyed by a high-pressure dyeing method, and the tufted carpet is formed into 1/8 gauge high cut / low loop. The surface material may be needle-punched carpet, and the pile may be made of 100% antibacterial fiber containing antibacterial ceramics (the raw material is kneaded with the antibacterial ceramics when manufacturing the yarn). Also,
The pile may be mixed twisted or mixed woven with the antibacterial fiber mixing ratio of 30% or more with respect to the non-antibacterial fiber (natural fiber, chemical fiber or a combination thereof).

Antibacterial ceramics are added to the back surface of the base cloth 2 in a weight ratio of 1% or more (preferably 1 to 10%).
80g / m of NBR latex kneaded at a ratio of
² (at the time of drying) to prevent the pile 3 from coming off (stopping). It is also possible to include antibacterial ceramics only in the surface material, and to make a product with a conventional structure other than the above. If the surface material is NBR latex containing the antibacterial ceramics, the slip-out prevention 4 is performed, and then the usual backing is performed. Good as a product.

On the other hand, the illustrated dust control mat 1
Is a backing material 5 made of synthetic rubber (NBR) in which antibacterial ceramics are kneaded at a weight ratio of 1.5% (the weight ratio may be 1% or more [preferably 1 to 10%]). It is used and is formed to have a thickness of 1 mm to 5 mm. A synthetic resin mixed with antibacterial ceramics may be used instead of NBR.

The tufted carpet and the backing material 5 are integrally molded by a high temperature press machine to form a dust control mat having an excellent antibacterial effect. As the antibacterial agent, it has excellent heat resistance, does not dissolve in water, does not dissolve in water even if a detergent is used, and does not dissolve in a solvent. Moreover, silver and zinc having an extremely high sterilization effect are used. Zeolite ceramics melted and mixed can be preferably used. Alternatively, the backing material may include antibacterial ceramics only, and the surface material may be a carpet that does not include conventional antibacterial ceramics. Furthermore, backing material 5
The surface material including the anti-pile-off material 4 of the pile and the antibacterial ceramics may be made of a conventional carpet containing no antibacterial ceramics.

[0014]

As described above in detail, according to the present invention, even if the dust control mat for rental is repeatedly washed, the antibacterial effect can be maintained continuously without lowering the antibacterial effect. It is possible. Therefore, it is possible to obtain a dust control mat that can maintain good hygiene for a long time.
