Ticket number is a commercial
numbering system usually used for sewing thread. Ticket
numbers resemble the fixed-weight system that shows the number of unit length
that gives a fixed weight. They can simply denote the higher the ticket number
the finer the thread and the lower the ticket number the thicker the thread. Ticket
number is calculated via the resultant count, recalculated into three fold
terms whatever the number of plies of yarns twisted together to form the
thread. There are two ticket (tkt) numbering systems used-
1. Cotton ticket number system
The cotton tkt number system
for sewing thread is based on a threefold equivalent of the Number English
system and relates its number to the finished thread rather than to the single
yarns from which it is made.
2. Metric ticket number system
The metric tkt number system for sewing thread is based on a threefold equivalent of the Number metric system and relates its number to the finished thread rather than to the single yarns from which it is made.
Last three examples of above show that the same ticket number for the more different thread construction but to the user the size of the final thread is same. (Pls. note regarding thickness 60 cotton tkt no is not same as 60 metric tkt no.)
