Abstract

A resin-coated non-woven fabric is provide that may be welded through a high-frequency welder and may be remedied in hardness, and further may have a clear embossed pattern. A resin-coated non-woven fabric of the present invention comprises: a filament non-woven fabric that is of a thermocompression-bondable type, is made of a polyethylene terephthalate and has a weight of 50 to 150 g/m2; and a resin coat layer positioned over one surface of the filament non-woven fabric and having a coating amount of 40 to 150 g/m2 after dried; wherein the resin coat layer contains 10 to 45% by mass of a vinyl chloride unit and 30 to 55% by mass of a (meth)acrylic acid ester unit, and further a surface of the resin coat layer has an embossed pattern.

First claim

The invention claimed is:

1. A resin-coated non-woven fabric, which comprises
a filament non-woven fabric that is of a thermocompression-bondable type, is made of a polyethylene terephthalate, and has a weight of 50 to 120 g/m 2 , and
a resin coat layer positioned over a surface of the filament non-woven fabric and having a coating amount of 40 to 150 g/m 2 after dried, wherein the resin coat layer contains 10 to 45% by mass of a vinyl chloride unit and 30 to 55% by mass of a (meth)acrylic acid ester unit, and
a surface of the resin coat layer has an embossed pattern,
wherein the resin-coated non-woven fabric has a strength of 65 N/cm or more when the fabric is broken by pulling at a pulling rate of 200 mm/min.

2. The resin-coated non-woven fabric of claim 1 , wherein the resin coat layer has at least one glass transition temperature (Tg) of 30° C. or lower according to differential scanning calorimetry (DSC) of the layer.

3. The resin-coated non-woven fabric of claim 1 , wherein the filament is not subjected to entangle with needle punching.

4. The resin-coated non-woven fabric of claim 1 , wherein the filament non-woven fabric has an embossed surface and a non-embossed surface, the resin coat layer is positioned over the embossed surface, and the filament non-woven fabric has no resin coat layer on the non-embossed surface.

5. The resin-coated non-woven fabric of claim 1 , wherein flexibility of the resin-coated non-woven fabric is from 80 to 160 mm, and tensile strength of a high-frequency welder welded portion of the resin-coated non-woven fabric is 5.0 N/cm or more.

6. The resin-coated non-woven fabric of claim 3 , wherein flexibility of the resin-coated non-woven fabric is from 80 to 160 mm, and tensile strength of a high-frequency welder welded portion of the resin-coated non-woven fabric is 5.0 N/cm or more.
