The invention provides a pure physical and pollution-free extraction technology for bamboo fibers. By means of the technology, coarse bamboo fibers with the diameter ranging from 0.03 mm to 0.3 mm, the length larger than 20 cm, the elongation at break ranging from 3% to 7%, the break force ranging from 3 N to 15 N and the break strength ranging from 100 MPa to 600 MPa can be obtained. The technological process includes the steps of pretreatment, high-temperature and high-pressure cooking, mechanical softening fibrillation, screening and separation, drying, and packaging and warehousing, wherein pretreated bamboo chips are put into a cooking container to be cooked and softened for 14-15 h, and then mechanical grinding fibrillation is performed through a softening machine. The product prepared through the technology meets the requirement for bamboo-plastic composites, production cost is low, the technological process is short, cleanliness and environment friendliness are achieved, and preparation is simple and easy.
