Abstracts:
Abandoned hair, which was a excellent natural protein fibre and was used as raw material in this experiment, was processed into hair power and followed by added into fiber to modify,final was made into spinning dope to prepare regenerated fibre.
For ensure the integrity of molecular structure of natural protein, the physical crushing method that hair after degumming and degreasing treatment could be broken into different grade powder under the influence of composite force, which was composed by impact force, extrusion force and strong shear force, and through a series of technological processes, aftre which the mean grain size of the ultrafine powder was less than or equal to 50um.
Several influence factors of using hair power prepared regenerated fibre were investigated in this experiment.
Key wordsL: abandoned hair, ultrafine powder; complex fiber |
