Modificación de la estructura de la fibra de Poliéster en la manipulación industrial de los artículos de lana/poliéster.

Joaquín Gacén Guillén, J. M. (José María) Canal Arias, José Valldeperas Morell


The influence of steaming, blind dyeing using carriers, treatments with water and heatsetting on the critical time of dissolution of the polyester has beeen studied on woll/polyester yarns. This technique is relatively simple and detects structural variations of the fibre.
It has also been checked that samples heatset, at different temperatures, show differences in colour determined by appling the formula ANS 40.
Criteria are given to establish until what extent the physical estructure of polyester is responsible of the faults in dyeing wool/polyester yarns.
