Abstract:
|
The anomalous behaviour of polyamide 6.6 fibres textured by false twist to different physico-chemical techniques (as the critical dissolution time, CDT), compared with those obtained in polyester fibres, was attributed to a cracking of the. surface and/or to an increase in fibre porosity. This cracking appears when original fibre is treated at high temperature and it is due to the breakage of the skin/core structure of polyamide 6.6. This cracking has been demonstrated by the determination of drying kinetics in a thermogravimetric test that has been developed for this fibre |
