The present invention relates to an interior decoration sheet and a method for manufacturing the same, and more particularly, to an interior decoration sheet and a method for manufacturing the same that can provide excellent visual effects and construction convenience.

In order to achieve a decorative function, the interior decoration sheet of the prior art forms a printed layer on which a design of metal, wood, and fabric is given by printing or transferring method on a colored PVC sheet, and then laminated with a transparent PVC sheet and then using heat. Physical or chemical treatments impart texture and surface depth.

The interior decoration sheet by the above printing or the like is inferior in surface texture and skin contact when compared with the actual fabric. Thus, there has been an attempt to achieve a more gentle and luxurious decorative effect by using the visual effect of the fabric tissue using the actual fabric.

For example, Korean Patent Laid-Open Publication No. 1989-1736 discloses a decorative sheet for inserting fibers between transparent resin layers and steam heating and pressing. However, since the expression of the surface texture and three-dimensional feeling of the fabric is lost, there is no significant difference from the decorative sheet composed only of the resin layer.

In addition, Korean Patent Laid-Open Publication No. 2005-89118 discloses a flameproof interior film in which a polyurethane resin adhesive is applied and laminated between a fibrous layer and a PVC film, but the adhesive force between the fiber and the substrate is not sufficient, and thus it is easily separated and torn. In addition, even during construction, the interface breakage between the fiber and the substrate occurs to significantly reduce the value as a product, there is a problem of product shrinkage phenomenon in the product storage in the long term.

In addition, when the construction must be a separate finish through taka (tacker) work, the workability is very poor, there was a lot of complaints from the builders and consumers.

In order to solve the above problems, a method of using an adhesive directly on the decorative fabric is used, but since the adhesive needs to be applied separately, the finishing is difficult, and inconveniences in construction and cost increase occur.

Therefore, the present invention can secure the adhesion and dimensional stability of the fabric layer at the same time, to solve the problem of the function of the monotonous decorative fabric, and at the same time implements excellent fabric appearance effect and construction without the need for additional finishing work such as Taka work To provide a fabric interior decoration sheet and its manufacturing method.

In addition, by introducing a surface treatment layer to the fabric layer, if necessary to provide a unique appearance of the fabric as well as to provide an interior decoration sheet having a variety of physical properties such as antifouling, antibacterial and a manufacturing method thereof.

In order to achieve the above technical problem, the present invention provides an interior decoration sheet including a substrate layer, an adhesive layer, a primer layer and a fabric layer in a stacked form in turn.

In addition, by providing an adhesive layer and a release paper on the exposed surface of the base layer, if necessary, to provide an interior decorative sheet that can achieve the effect of convenience and cost reduction in construction.
