THE TECHNOLOGY FOR PRODUCING PBT BULK CONTINUOUS FILAMENT (BCF) |
| |
| Abstract: | The technology for producing PBT-BCF by using PP-BCF spinning machine was
studied. The viscosity η] of raw material PBT is 0.9 and water content 2.5‰ after
drying. The spinning temperature is controlled 10-15℃ lower than that of PET. PBT
-BCF can be dope-dyed with master batch for PP fiber. The spinning finish for PET
filament yarn is applicable to PBT-BCF. The property and application of raw mate-
rial and products are introduced in this paper. |
