Abstract

Procedimento selezionatore di polipropilene nella lavorazione dello schappe di seta in cui un velo di fibre di seta (11) semipettinate, o quantomeno sufficientemente parallelizzate, viene sottoposto ad un'azione di riscaldamento tra 110°C e 160°C, con contemporanea azione di compressione controllata per la formazione di grumi di polipropilene e fibre di seta, e successivamente ad un'azione di pettinatura o prepettinatura per l'asportazione definitiva di detti grumi.Selezionatore di polipropilene nella lavorazione dello schappe di seta posto a valle di uno stiratoio (13) o di macchina analoga producente un velo di fibre di seta (11), presentante un mezzo di trasporto (nastro/tamburo) cooperante con mezzi di pressione regolabile su detto velo (11).
