Abstract

The invention relates to a compound function type bamboo pulp fibre prepared by taking white bamboo charcoal as a functional material and a preparation method thereof. In the prepared compound function type bamboo pulp fiber, the fiber content is as follows: absolute dried fiber content is 85-93% in terms of weight, the balance water and impurities remained in the fiber production process like water, oil, etc. In the invention, the fiber far-infrared emissivity is more than 82%, the anion concentration is over 2000 / cm<3>, the sterilizing value is larger than 0.3, and the bacteriostatic value is larger than 2.0, thus preserving the excellent performance of bamboo pulp fiber such as hygroscopicity and permeability, softness and smoothness, antibiosis and the like and creating a new field for developing functional fiber.

Description

technical field [0001] The invention relates to a composite functional fiber, more precisely, a composite functional bamboo pulp fiber integrating far-infrared functions, negative ion functions, antibacterial and antibacterial functions and a preparation method thereof. Background technique [0002] At present, the consumption of various textiles is increasing day by day, and traditional textiles can no longer meet people's consumption needs. With the advancement of technology, many functional textiles have been developed, and health care and physical therapy textiles with far-infrared anion functions are very popular. The development of fibers with composite functions such as emitting far-infrared rays and releasing negative ions has a relatively broad market prospect. [0003] The method of producing far-infrared negative ion fibers at home and abroad is mainly to implant ultrafine powders of materials such as tourmaline, medical stone, strange ice stone, and black bamboo...
