The Metric Count, Cotton Count and Denier Systems use ticket numbering system to give an easy approximation of the specific size of the finished thread.Ī ticket number in one type of thread will not be the same as in another. Ticket numbers are merely the manufacturer’s reference numbers for the size of a given thread. Ticket numbering is a commercial numbering system. Using the table below will enable you to perform a simple conversion from one system to another. In fixed length systems: Resultant size = Individual yarn count x Number of pliesĪ particular resultant size can be made with any number of plies.In fixed weight systems: Resultant size = Individual yarn count / Number of plies.When more than one ply of yarn is twisted into a thread, finding the resultant size of the thread by considering all the plies becomes necessary. Filament threads are normally expressed with Decitex or Denier. Generally, Metric count is used to describe synthetic, spun and corespun thread while English count is used to specify cotton thread. In fixed length systems, the yarn becomes coarser / heavier as the count number increases In fixed weight systems, the yarn becomes finer as the count number increases Tex 100 – A length of 1,000 metres gives 100 Grams of weight.Tex 40 – A length of 1,000 metres gives 40 Grams of weight.Ne 5 – In one pound of yarn weight, there are 4200 (840x5) yards of yarn length.Ne 1 – In one pound of yarn weight, there are 840 yards of yarn length.Decitex = Weight in grams of 10,000 metres.Denier = Weight in grams of 9,000 metres.Metric Count (Nm) = Number of hanks of 1000 metres/kg.English Count (Ne) = Number of hanks of 840 yards/lb.In this system, unit length is taken as fixed and its weight is measured. In this system, unit weight is taken as fixed and its length is measured. Fixed Weight and Fixed Length Numbering SystemsĪll numbering systems used to indicate thread size are either 'fixed weight' or 'fixed length' systems.
It is important to know various numbering systems and their relationships in understanding thread size specifications this Bulletin Post will serve as your quick reference guide. Thread sizes are communicated through various numbers and numbering systems which are derived by relating its unit length and weight. Thread selection for any specific application is based on many parameters, thread size is the primary consideration in achieving the functional and aesthetics requirements of the finished product.
