Libgdx texture region to texture

I want to use setFilter(TextureFilter.Linear, TextureFilter.Linear); on my image, taken from textureAtlas. when I use

TextureRegion texReg = textureAtl.findRegion("myImage");
Sprite = new Sprite(texReg);

it's works fine, but if i try

TextureRegion texReg = textureAtl.findRegion("myImage");
Texture myTexture = new Texture(texReg.getTexture());
myTexture.setFilter(TextureFilter.Linear, TextureFilter.Linear);
Sprite mySprite = new Sprite(myTexture);

mySprite contains all textureAtlas images. How to set to Texture single image from textureAtlas?
