Description
Technical field
The invention belongs to the cellulose bamboo charcoal fibre field, particularly relate to a kind of solvent method preparation and application of cellulose bamboo charcoal fibre.
Background technology
Not only storage level is big for cellulose in all substances of occurring in nature, and huge amount of recovery is arranged.Have only few cellulose to be made into fiber at present.Be used to make the cellulose amount of fiber and film, 4% of the cellulose output of producing no more than world industry.Along with the mankind to the deepening continuously and the worsening shortages of resources such as oil, coal, natural gas of nature understanding, cellulosic utilization also will enlarge gradually.Cellulose fibre is because raw cellulose can be changed into steam and carbon dioxide by biological decomposition or safe combustion, and the destruction environmental problem that is caused by discarded object is few.Therefore it is very necessary developing cellulose fibre.Wherein, make the semi-products of regenerated celulose fibre---the raw material source of pulp is also quite extensive, from the needlebush of high-quality and cotton linter to leaf wood, fast growing wood, bamboo and various herbaceous plant (as bagasse, reed, jute bar etc.).
What at present produce cellulose fibers mainly adopted is viscose process, and production process is tediously long and complicated, energy consumption and operating cost height, and exist waste gas, waste water, waste residue pollution, handle multinomial problem such as recovery.And ionic liquid exists with liquid state in the scope of broad as a kind of novel cellulose solvent, and has good heat endurance, and nontoxic, non-volatility helps environmental protection and operator ' s health.Can change its physicochemical properties by the yin, yang ion population of selecting to suit, be the good solvent of many organic matters, inorganic matter and macromolecular material.Many ionic liquids are very big to cellulosic solubility, some in addition reach 35%; Be no more than 10% and adopt cellulose yellow method to produce the cellulose concentration that viscose adopted, therefore adopt the ionic liquid produce cellulose fibers to enhance productivity greatly.
Internal surface of hole countless in the bamboo charcoal is long-pending, adsorbable Za Quality, toxin and moisture content, even Ju You Yuan Red outside line release action.Therefore, bamboo charcoal has characteristics such as excellent hygroscopicity, adjustable wet, deodorizing antibiotic, heat storing and heat preserving, red place far away and anion release, electromagnetic radiation shielding.Bamboo is applied to building, interior decoration more and more and even is made aspects such as fiber and dress material in China as a kind of high-quality natural material elsewhere.Therefore, the exploitation bamboo charcoal cellulose fiber has realistic meaning.
The cellulose bamboo charcoal fibre report that sees report at present mainly is to adopt viscose process production: disclose a kind of method of producing bamboo-carbon viscose fibre as Chinese patent 200320110113.9,200610037895.1,200510102775.0.
