Last week we discussed one of the three key elements in evaluating the quality of your personal #coolingsolution … Absorbency. KewlFabric 7101 passes the absorbency litmus test, exceeding other supposed evaporative cooling fabrics by a significant margin both pre and post washing. Absorbency is crucial and drives cooling capacity and cooling duration. Afterall, it is hard to get a good evaporative cooling capacity score without being able to absorb water.
In an earlier post, I released a video that discussed the cooling capacity of KewlFabric 7101Â Cooling capacity is the second of three key evaluation metrics when looking at an evaporative cooling solution.
There is a specific test that can be run to measure cooling capacity in W/cm2 and the results for KewlFabric 7101 were very good. KewlFabric 7101 had an average score of 0.231 W/cm2.
What this means is that at a specific point in time a temperature measurement was taken of the fabric once activated. This usually occurs shortly after activation and is not a measurement of cooling over time.

This Qmax measurement tells you how much cooling the fabric kicks off when evaporating the water it has absorbed.
Many wicking fabrics conduct a cooling capacity test and present it as conclusive evidence that their fabric is the best on the market because it has a high cooling capacity rating (Qmax). The below chart reflects some testing done against some well known materials used in making cooling fabrics. Please note that I have left out specific brands, that use these fabrics, from this review. There are several wicking fabrics that get a higher Qmax score than KewlFabric 7101. Remember a high Qmax score only means that at a set point in time, the fabric reaches that specific cooling capacity.
No one talks about their cooling capacity after 3,4 or even 8hrs. Why is this the case? Because their cooling solutions are no longer cooling. They often dry out after about 1hr. These wicking fabrics make great cooling towels, and to be fair, are sold as such, but they should not be used to make cooling garments such as vests, or neckshade or hats etc as some have tried.

We at KewlFabric Solutions are happy to discuss our cooling capacity over 3,4 or even 8hr durations when discussing KewlFabric 7101, but more on that later.
So, Kewl Fabric 7101 absorbs alot of water even after 40 wash cycles and has a very good cooling capacity helping you to create an #activecooling garment solution. What finally knocks it out of the park is when the absorbency and cooling capacity of KewlFabric 7101 are combined with its cooling duration. Next week we will take a look at how the Absorbency and Cooling Capacity of KewlFabric 7101 match up with its Duration.
