All lines will do that if they are not rinsed after use and or not used for a while. Pull 200 yards of mono off a reel that is a year or two old and has not typically been pulled out and it will stick. Braid is just worse about it because of the nature of the line. Being a woven material it can absorb water. When the water evaporates all the minerals including salt are left behind, basically forming a soft glue holding the line together. While rinsing helps it will not cure the problem. They do sell braid cleaner which, helps but is not a cure. Just one of several reasons all lines need to be replaced periodically.
