You’ve probably heard of xylitol, but do you know it could be used in fabric technology to actually cool you down?
Xylitol is an all-natural sugar that occurs in some fruits. In addition to its sweetening properties which we often use as a sugar alternative, xylitol also has an endothermic (heat-absorbing) reaction when it comes into contact with moisture. Adding xylitol properties to the yarn brings out the cooling touch in the fabric once exposed in moisture.
After about 10 minutes of wear, body moisture activates the finish, which then starts absorbing heat. It’s a fantastic way to help the body’s own cooling system work even better which makes the cooling technology ideal for humid conditions, indoors, or on a hot day with no breeze.
Ultra Shirt made with S.Café ICE-CAFÉ which is an ice-cool yarn made with xylitol cooling tech and recycled coffee grounds, provides thermal regulation, and cooling effect. The cooling effect is activated by body moisture which absorbs body heat and dissipates it quickly. This finish doesn’t just create a cooling sensation but actually cools the skin by 1.8 – 5.4 °F (1-3 °C).
