Hello, Firstly thank you for such videos. I have a question. What is the main difference between ISO 3071: a method for determining the pH of the aqueous extract of textiles and AATCC 81: pH of water extract from wet processed textiles. Which method should we choose according to which request?
@Testextv2 жыл бұрын
3071 is shaking method and applicable for European customers. AATCC 81 is boiling method and applicable for American customers.

Thank you for your kindly response. I want to ask one last question to make it clear to me. When we apply both methods to a fabric, the pH value is still the same, right? Thank you in advance for your reply.

Why use KCL ? please

0.1N Kcl is use in ISO-3071 PH as distilled water. Because Kcl stabilize the PH operator check PH most time repeatedly its PH constant. Instead PH perform with distilled water.
