Yarn Count (Tex)
Compute a yarn's count in the Tex system, Tex = (mass in grams / length in meters) · 1000, i.e. the mass in grams of 1000 meters of the yarn. It is a 'direct' system (the higher the number, the thicker the yarn), standardized internationally. Tex links mass to length — the fundamental quantity defining yarn fineness and influencing strength, hand and fabric weight. Enter the mass and length of the yarn sample.

Título do fio (Tex)
Como medir a 'grossura' de um fio, que tem espessura irregular? A indústria têxtil resolve isso pela relação massa/comprimento. No sistema Tex, o título é a massa em gramas de 1000 metros do fio: Tex = (massa/comprimento)·1000. É um sistema direto e intuitivo — fio mais grosso, número maior — e padronizado pelo SI têxtil. Variantes: o decitex (dtex, por 10.000 m) é comum em filamentos. O título do fio é a grandeza mais fundamental da fiação: define quantos fios cabem num tecido, sua resistência, o toque e, somado à densidade de fios, a gramatura final do tecido. Informe a massa e o comprimento da amostra de fio.

Tex ↔ Ne Conversion
Convert a yarn count from the Tex (direct) system to Ne (English count, indirect), Ne = 590.5/Tex. In the Ne system, unlike Tex, the higher the number the <em>finer</em> the yarn — so they are inversely proportional. Ne is traditional in cotton spinning. The conversion is essential to compare yarns specified in different systems. Enter the count in Tex.
Yarn Twist (TPM)
Compute a yarn's twist in turns per meter (TPM) by dividing the number of turns by the length. Twist is what holds the fibers together and gives the yarn strength: too little produces a weak, fuzzy yarn; too much, a hard yarn prone to kinking. The direction (S or Z) and twist level define the yarn's character — knitting yarns are low-twist, crepe yarns high. Enter the number of turns and the length.
Fabric Cover Factor
Compute a fabric's cover factor, CF = thread density (threads/cm) · √(Tex), an index of how 'closed' the weave is — how much the threads cover the area, leaving more or fewer open spaces. High factors indicate dense, opaque fabrics (canvas, twill); low ones, sheer, breathable fabrics (voile, mesh). It influences air permeability, opacity and strength. Enter the thread density and the count in Tex.
