There are a couple of ways to interpret the word "disassemble" when referring to recycling neckties.  I have been given ties that are COMPLETELY taken apart, even to the point of removing lining from the tips.  I prefer to save the tips intact.  Unless I plan to use the tie with the tips intact, I always cut about 3" off each end with the lining intact in order to use those tips as prairie points or other embellishment.  Then you can remove the remaining bits of end lining.  Some ties have an additional underlining layer, which I do remove before using the tie.
