The drawing of polymer mono- and multifilaments is a running process in which the draw ratio is obtained by varying the speed of the godets. This process provides orientation in the polymeric structure of the filament(s) which typically leads to improved mechanical properties.
This R&D drawing set-up is ideal for experiments with multifilament yarns and monofilaments. It allows you to variate the key parameters involved in the drawing of filaments. As we can operate the equipment with a low throughput, you can obtain many variables with relatively low material loss. After the drawing trials the performances can be measured.
With our draw frame it becomes possible to process monofilaments and multifilament yarns in a 2-step process, however, we have a flexible setup consisting of 3 fixed godets, a mobile godet, a hot pin, a hot plate, a temperature gradient plate and a 3 meter long oven. Next to that the godets can be heated. The standard setup consists of a creel, godet 1, hot pin, godet 2, oven, godet 3, winder. However this setup can be extended with various equipment like a intermingler, spin finish applicator, kiss-roller etc. Possibilities are unlimited. You can even fit in your own equipment.
The draw frame is used to obtain information about the maximum draw ratio of yarns and to gather information of the draw ratio, yarn tension and the influence on the tenacity of the drawn yarns.
