Remark:  Absorbency detects time of water drop that adsorbs through a textile sample in horizontal plane

   Wicking detects distance of water that is adsorbed through a textile sample in vertical plane for 10 minutes

 

Testing laboratory:

Organizations that apply for “CoolMode” certification shall submit laboratory testing reports from the Thailand Textile Institute according to “CoolMode” characteristic requirements. The laboratory testing cost shall be covered by the organizations themselves.  After completion of the characteristic requirements testing, the organization shall submit the relevant testing report with completed “CoolMode” application form to TGO to proceed with the “CoolMode” certification.
