How thick is a human hair...

Surprising facts about manmade fibers ...

Filament thickness against a hair from an average Central European person:

1. FDY microfiber filament (fine titer)
2. Silkworm thread
3. Cotton fiber
4. POY (medium titer)
5. Wool fiber
6. BCF yarn (medium titer)

Thread length: from Frankfurt to Hong Kong and back ...

To wind a 14-dtex nylon thread into a 25-kg package takes about 61 hours. The thread on the package is around 18,400 km in length. This corresponds to the distance between Frankfurt and Hong Kong and back.

Or: the yarn on four packages of a winding cycle, here several packages are simultaneously wound on a take-up head, would reach almost twice around the equator.

What exactly is that ...

Filament
A filament is a spun and wound endless manmade fiber. The number of filaments in filament yarn corresponds to the number of holes in the spin nozzle.

POY
Pre-Oriented Yarn :the spun yarn has not yet been fully drawn. It is used in textiles that are, for example, finished using Barmag draw-texturing machines.

FDY
Fully Drawn Yarn: following the quenching process, this yarn is fully drawn and wound on so-called godets.

BCF
Bulked Continuous Filament / textured carpet filament yarn:BCF yarn is fully-drawn and crimped in a one-stage process. In this form, it can be processed into carpets and home textiles.

Industrial yarn
Particularly break-resistant and shrink-resistant fully-drawn threads, which are used in automobile tires, belts and airbags.

Titer
Measure for determining the fineness of filaments and filament yarns, for example in dtex.

dtex
The dtex measure unit determines the weight in grams of 10,000 meters of a filament or yarn.

Godet
Godets are fast-rotating, cold or heated rollers which guide manmade fibers. They are normally used to draw the thread at varying speeds.
