The heat and the light are not physically different things. If the light is absorbed, then the object that absorbed it was heated by that amount of energy.If the heat escaped, that would mean the light was reflected, and it wouldn't be black, it would be white. (Or a mirror, depending on how consistent the angle of reflection is)
Yes and no.
Visible light carries energy, and hence, yes, absorbing visible light will heat the fabric. However, at temperatures less than a thousand degrees or so, most of the heat energy is carried in infrared light. Since the fabric is specified as being black in visible light, it may or may not be absorbing in infrared.
