Titration
The yarns intended for the manufacture of fabrics come in different thicknesses, so it is necessary
be able to measure them. Not being practically possible to measure the diameter due to the easy
deformation of their section, a distinction is made to titration.
The titration of the yarns is based on the knowledge of two sizes: the LENGTH (L) and the WEIGHT (P).
By relating these two quantities we have values called:
- Titles (T) in the method of direct titration
- Numbers (N) in the method of indirect titration.
The DIRECT METHOD, said to fixed length and variable weight, is given by the weight ratio divided
the length (T = P / L). This method is commonly used for all yarns made from fibers
continuous (silk, rayon, nylon, etc.).
The title Tex (Tex) indicates the weight in grams of 1000 meters of yarn. For example, Tex 1 means that
1000 meters weigh 1 gram.
This titration method is called universal and should replace all titrations, especially
of the indirect system (N).
The title Decitex (Dtex) indicates the weight in grams of 10,000 meters of yarn or filament. This method
it is used for burrs or for multi-filament yarns. For example, Dtex 1 means 10,000 meters weighs
1 gram (burr).
The title Coins (Den) indicates the weight in grams of 9000 meters of yarn or filament. It is used for burrs, yarns
multi-filament and for silk. For example, Den 1 means 9,000 meters weighs 1 gram (burr).
With the direct method, the number indicating the count is higher the thicker the yarn (or the
burr), the fineness being expressed as a function of the variable weight with respect to a fixed length.
Others
The INDIRECT METHOD, also called with fixed weight and variable length, is given by the relationship between
the length and weight (N = L / P). Titration with this method (N) is commonly used
for all yarns made with discontinuous fibers (wool, cotton, rayon staple, etc.).
The most used indirect titles in the Prato area are:
• metric and kilogrammetric titration;
• English titration of cotton;
• Prato titration.
There are also the English titration of carded wool, the English titration of worsted wool, the
English titling of flax and hemp.
The metric number (Nm) indicates how many meters of yarn there are in 1 gram. For example, Nm 1 means
1 meter of yarn on 1 gram.
The kilogrammetric number (Nkgm) indicates how many meters of yarn there are in 1000 grams. To
example, Nkgm 1000 means 1000 meters of yarn per 1000 grams.
This titration is also used in the Biella area for thick yarns. For example Nm 7 is called
also Nkgm 7000 or simply 7000.
The English number of cotton (Ne, Nec or Ne cotton) indicates how many skeins of 768 meters (equal to
840 yards) there are about 454 grams (equal to 1 pound) of yarn. For example Ne 1 means 1 skein
of yarn of 768 meters weighs 454 grams.
This titration is used for cotton and is also in use in Italy.
The Prato number (Np) indicates how many skeins of 583 meters (equal to 1000 Tuscan arms) there are on 339.5 grams (equal to one Tuscan pound) of yarn. For example, Np 1 means that 1 skein of
583 meters weighs 339.5 grams.
The Prato number is divided, in the decimal part, into quarters (1/4, 1/2, 3/4) and is used in the district
Prato only for carded yarns.
From the above, the number being a function of the variable length with respect to the weight
fixed, the higher the number, the finer the yarn.
