  1. Can you please describe me the basic characteristics of Pigments used in textile printing and especially its behaviour related to Perspiration and Saliva fastness properties?
    Is Perspiration & Saliva fastness is builtin properties of pigments?

  2. The topic was adequately addressed but not thoroughly. This article is in desperate need of editing. Several sentences make no sense. All-in-all I was not very impressed.
