Embodiment Construction

[0023] The technological method that adopts polylactic acid base to produce nano-bamboo charcoal fiber comprises the following technological steps:

[0024] (1) Selection of raw materials:

[0025] The polylactic acid chips used in the present invention are self-made by Anhui Hesheng Technology Co., Ltd., with a molecular weight of 335,000, a melting point of 162°C, a crystallinity of about 76%, a glass transition temperature of 58.5°C, and an L-isomer content of more than 99% of the slice molecules. The nano-bamboo charcoal powder is commercially available black 18000 order of Shanghai Ke Ruisen Environmental Protection Technology Co., Ltd., the specification of 100nm; Among the present invention, the mass ratio of polylactic acid slice and nano-bamboo charcoal powder is: polylactic acid slice 95%, nano-bamboo charcoal powder 5%.

[0026] (2), raw material mixing and drying:

[0027] The polylactic acid slices and nano-bamboo charcoal powder are mixed according to the ratio ...

Abstract

The invention discloses a process for producing nanometer bamboo carbon fiber by adopting a polylactic acid group. In the process, the nanometer bamboo carbon fiber is produced from polylactic acid as a carrier and nanometer bamboo carbon powder by a dry spinning technology. The nanometer bamboo carbon fiber produced by the invention has the advantages of greenness, environmental protection, easy recovery and degradation, low carbon emission during production, simple production process, easy operation and low cost.

Description

technical field [0001] The invention relates to a process method for industrialized production of nano bamboo charcoal fibers, in particular to a process method for producing nano bamboo charcoal fibers by using polylactic acid base. Background technique [0002] In modern society, it has become a trend to research and produce functional textiles that are beneficial to human ecology and health. Bamboo charcoal is a new type of functional material and an environmentally friendly material with excellent performance. It has the reputation of "black diamond" and is known internationally as "the new guard of environmental protection in the 21st century". It is a new development direction for the effective utilization of bamboo resources. Bamboo charcoal fiber is a new type of fiber that is made of nano-scale bamboo charcoal powder (bamboo charcoal micropowder), which is added to slices or spinning liquid through a special process, and then spun by a similar conventional spinning ...
