Thread marking "Ttex"
Ttex is the official designation for yarn fineness in the textile industry and its abbreviation is "tex". It is a metric unit that expresses the weight of the yarn in grams per 1000 meters. The first number therefore expresses how many grams 1 km of yarn weighs. The other numbers then indicate how many simple/basic yarns the resulting thread is woven from. It follows that the higher the first number, the stronger the basic thread (greater thread weight per 1 km).
Example:
Len Thread 33 tex x2x8 - the basis is a linen thread whose 1 km weighs 33 g. The resulting thread is woven from two basic threads, which are further woven from 8 of these pairs. After unraveling, you will find that this thread is woven from a total of 16 basic threads of 33 tex.
