Abstract
The traditional PES spunbond line, compared with the PP product line, demands additional device in order to obtain the final web: a stabilisation furnace to definitely orient the web and prevent it from shrinking out of control at high temperatures, should it not be fully oriented by problems of the spunbond process. The core idea is to make polyester spunbond without a stabilizing draw setting. Therefore we tried to keep the PP devoted nonwoven manufacturing line introducing a pre-dryer while cutting off the stabilising furnace. In order to achieve quality this principle, we maximized orientation of the filaments as much as possible at the spinning stage, maximising the fibers drawing ratioPubblicazioni consigliate
