"HG/T 5165-2017 Spinning & weaving dyeing and finishing aids, anti-wrinkle finishing agents, determination of anti-wrinkle performance" specifies the determination method for the anti-wrinkle performance of anti-wrinkle finishing agents in Spinning & weaving dyeing and finishing aids. This standard is applicable to the quantitative evaluation of the anti-wrinkle performance of anti-wrinkle finishing agents in Spinning & weaving dyeing and finishing aids. The standard compares the performance of fabrics before and after finishing by using an anti-wrinkle finishing agent under specified conditions, and then uses a crease recovery angle or Appearance Smoothness rating method to evaluate the effect of anti-wrinkle finishing agents. To ensure the accuracy and Reliability of the determination, the standard refers to a number of relevant test methods and laboratory water mass standards.
