Estudio comparativo entre cuatro distintos métodos para el control de calidad de los hilos texturados de Poliéster.

Federico López-Amo Marín


Polyester yarns textured under different conditions have been tested using four different quality control methods:
Shirley tube test; H.A.T.R.A. Crimp Rigidity Test, Hot Air retraction and Texturmat.
To increase their sensitivity and to achieve reproducible results, certain modifications have been introduced in each of them. As expected, each method gives differen results, but the tendency is the same. This suggests that any one of them can be employed as a quality control method, providing the «modus operandi» are carried our strictly.
