Yarn Information

Yarn Designation

Example: PA 6.6 78dtex/f46x4 Z88 text HE glz

Designation									Meaning
PA									Raw material Polyamide
	6.6								Raw material specification
		78 dtex							Weight per 10,000 m per hank
			f 46						Number of filaments per hank
				x4					Plying Quantity of hanks
					Z88				Twist Quantity of twists per meter with Z-twist
						text			textured
							HE		Elasticity highly elastic
								glz	Luster Glossy

Calculation of the single titer (single filament):

Formula:
Weight per 10,000 m per hank / Number of filaments per hank = Weight per 10,000 m per filament

Example: 78 g / f46 = 1.696 g (rounded)

Result: One filament with a length of 10,000 m weighs 1.696 grams.

Calculation of the final titer:

Formula:
Weight per 10,000 m per hank x Number of hanks = final titer by dtex

Example: 78 dtex x 4 = 312 dtex

Result: 10,000 m yarn weigh 312 grams.

Conversion from dtex into Nm:

Nm = Length in meters per 1 gram

Formula:
Weight: 1g x reference length dtex / final titer = Length in meters (Nm)

Example: 1g x 10,000 m / 312 g = 32.051 m (rounded)

Result: Approx. 32 m of yarn weigh 1 gram (Nm 32).
