At present, domestic outdoor practitioners and outdoor enthusiasts have misunderstandings or insufficient understanding of certain aspects of the functions of outdoor workwear. The following is a brief introduction to the meaning and difference of the functional indicators of water repellent fabric:
Anti-water: in the standard laboratory, with distilled water through the funnel spray on the sample, compare the water resistance standard sample rating;
Commonly used test standards are: AATCC-22-2005(scoring system); European standard: ISO 4920(rating system);
Comparison of ratings of US and European standards :100 points (level 5); 90 points (level 4); 80 points (Level 3); 70 points (Level 2); 50 points (Level 1); 0 points (Level 0).
There are three types of Water Repellent: Water Repellent (W /R) and Durable Water Repellent (DWR).
(1), general water resistance (W/R) : Wash a few times the surface of the clothing did not resist the water, the general outdoor water resistance can be used, the commonly used data is 70 minutes before the wash, if you often go to climb or have a certain altitude of the mountain, the climate is changeable on the mountain, it may rain at any time, the general water resistance of the work clothes washed several times did not block the water, resulting in the clothing surface will be wet, wearing the body will increase the weight of the human body.
(2), super water (DWR) : C8 produced by Daikin or other auxiliary companies in Japan blocks water, and maintains the effect of 80 points (European standard 3) after 20 washes; Because the fluorine content does not meet the EU standard, it has been banned by the EU. Now the adoption of C6,C4 more, generally washed 5-10 times to maintain the effect of 80 points.
