Abstract
A process and apparatus for manufacturing a microfiber structure for absorbing impact energy, sound energy and/or temperature, the structure being used in the ballistic field and in the sound and temperature isolation fields, wherein the method comprises to provide a plurality of threads consisting of microfibers, subjecting the threads to a pressurized air jet to open the threads by separating the microfibers into each thread and entangling the threads to form a mass of loosely-entangled microfibers, with the mass being confined the mass into a pack which may be appropriately compacted.
Claims27
A process for obtaining a microfiber structure for use in absorbing at least one of impact energy, sound energy and thermal energy, the method comprising the steps of:
- i. providing a plurality of spools containing polymeric threads, each thread consisting of microfibers;
- ii. unwinding from the spools the threads and guiding the threads into a collecting-guiding means;
- iii. pulling the threads from the collecting-guiding means;
- iv. bringing the threads into a microfiber separating station for transversely separating the microfibers into the threads but maintaining the longitudinal continuity of the microfibers into each thread;
- v. bringing the separated and spaced apart microfibers into entangling means for entangling the threads all together to form a mass of loosely-entangled microfibers;
- vi. providing an outer cover all around the mass in order to confine the mass into a pack;
- and
- vii. compacting the pack.
