Description

[Detailed description of the invention] [Industrial application field] This invention relates to a base material for interior decoration, and more specifically, for example, a base material such as a carpet laid on a closet floor of a house, or The present invention relates to an interior base material that is suitably used as a base material for use on the inner walls of vehicles.

[Prior art]

Conventionally, the base material laid on the closet floor of a house or the inner wall of a vehicle has been made by, for example, using natural short fibers made by unraveling jute bags and bonding them together with adhesive, or using natural short fibers made of natural short fibers. Those that are formed into a plate shape by being intertwined with each other by means such as needle punching are used.

[Problem that the invention attempts to solve]

However, this type of base material not only has poor cushioning and insulation properties, but also the temperature and humidity of modern houses, vehicles, etc., which are constantly maintained at high temperatures due to improvements in their structure or the performance of heating equipment. Under such conditions, mold or wall moths may grow, which is undesirable from a sanitary standpoint.

[Means for solving problems]

Therefore, in order to solve the above-mentioned problems, this invention uses short fibers made of acrylic synthetic cotton that has been treated with insect repellent treatment and polyester synthetic cotton that has been treated with antibacterial treatment in advance. The short fibers are intertwined with each other and formed into a plate shape by needle punching, thereby improving heat insulation and cushioning properties, and further preventing the generation of mold and wall insects.

[Effect]

The interior base material according to this invention not only improves cushioning and heat insulation properties due to the plate-like body formed from multiple types of short synthetic resin fibers, but also prevents the generation of mold, wall flies, etc. The mold, wall flies, etc. that occur in these areas are treated with antibacterial and insect repellent treatment to prevent their propagation or invasion.

〔Example〕

Next, preferred embodiments of the interior base material according to the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, the base material 1 according to the present invention is made by intertwining a plurality of short synthetic resin fibers 3 and 5 that have been previously treated with antibacterial and insect repellent treatment and formed into a plate shape by needle punching. It basically consists of:

That is, this base material 1 is made of short fibers 3 made of acrylic synthetic cotton that has been subjected to insect repellent treatment in advance.
(For example, product name: Buxer, manufactured by Kanebo Co., Ltd.)
Short fibers 5 made of polyester synthetic cotton that has been subjected to antibacterial treatment (for example, product name: Rib Fresh, manufactured by Kanebo Co., Ltd., product name: Biosil,
(manufactured by Toyobo Co., Ltd.) are well entangled with each other, formed into a plate-like body of a predetermined thickness by needle punching, and then integrated.

The ratio of the acrylic short fibers 3 and the polyester short fibers 5 of the base material 1 formed in this way is preferably about the same, and furthermore, the large number of holes obtained by needle punching has a large number of holes in the surface direction. This is preferable because it not only increases air permeability but also allows the short fibers to be entangled with each other more reliably.

On the other hand, in the case of insect repellent or antibacterial treatment for short fibers, it is sufficient to mix an insect repellent such as DET at the stage of manufacturing acrylic fiber 3. is antibacterial (e.g., product name: Irgasan DP-
300) is directly impregnated into the short polyester fibers 5.

The base material 1 configured in this way has a closet floor section,
After suitably cutting and laying the base material 1 on the interior of a vehicle, a finishing material such as a non-woven fabric or carpet may be fixed on the base material 1 with a suitable adhesive or the like, if necessary. In addition, if you install this base material on the wall or ceiling,
Of course, it can also be used as a sound absorbing material or a heat insulating material, and furthermore, it can be placed inside a chest of drawers and used as a mat for antibacterial and insect repellent purposes.

[Effect of idea]

As mentioned above, the interior base material according to the present invention not only has high cushioning properties and breathability, but also has excellent heat insulation and sound absorption properties, as well as synthetic fibers with good water repellency. Since it is a plate-shaped base material that has been treated with fungus and insect repellent treatment, it can prevent the growth and invasion of mold and wall insects for a long period of time.
Furthermore, it has various advantages such as being able to prevent bad odors caused by the growth of mold or wall moths, and its practical effects are extremely large.

The preferred embodiments of the interior base material according to the present invention have been described above, but the present invention is not limited to these embodiments. It goes without saying that various modifications can be made without departing from the spirit of the present invention, such as covering one side with a nonwoven fabric as necessary.

[Brief explanation of the drawing]

FIG. 1 is an explanatory cross-sectional view showing a preferred embodiment of the interior base material according to the present invention. 1: Base material, 3, 5: Synthetic resin short fibers.
