Description
Technical field
The present invention relates to fiber textile fields, and in particular to a kind of conduction ramee and preparation method thereof.
Background technique
The structure of ramee and performance: ramie, be otherwise known as " China grass ", is mainly planted in China and other Asia
Country is such as Philippine and India, and China's ramie yield the first in the world, account for whole world total output 90% [Liu L, Lao C,
Zhang N,Chen H,Deng G,Zhu C,Peng D,Ind.Crops Prod.2013,44(0):677.].It and cotton fiber
Natural fiber is belonged to, except that the non-cellulose components content of ramee is higher, these non-cellulose components are referred to as
For colloid, in colloid containing the substances such as hemicellulose, pectin, lignin, molten object, adipocere matter, ash content [Angelini L G,
Lazzeri A, Levita G, et a1.Ind.Crops Prod.2000,11 (2-3): 145；Ishikawa A, Okano T,
Sugiyama J, Polymer, 1997,38 (2): 463].
The application development of conductive fiber: the electrostatic hazard of textile in order to prevent, it is external that conductive fiber is carried out very early
Research.The development history of conductive fiber can be divided mainly into three phases, one, metallic conduction fiber: in the world for the first time for weaving plus
The conductive fiber of work is stainless steel [Zheng Shaoming, the Lai Xiang for the trade name Brunsment that Brunswich company, the U.S. produces
Brightness, the fine inspection of development and application [J] China of Lin Benshu conductive fiber, 2016 (09): 143-144]；Two, carbon black conductive fiber:
When to enter the seventies at once in 20th century, studying intensively and developing to carbon nanotube is passed through by Japanese Di Ren company, prepares eventually
The conductive fiber of carbonarius, has opened up the new application field of carbon nanotube.But since the color of carbon black fibre is in black gray expandable,
It is unfavorable for carbon black fibre being applied to the industries such as clothes, accessories, the conductive fiber of whitening is given birth in due course at this time.Such as Ji Kagong
The companies such as department, Ben Dongli develop manufactured conducting PET fibers and brocade falls, and conductive compositions are mostly the white metals chemical combination such as CuI
Object, this enters clothes for conductive fiber, drapery field opens new road [Nan yan Nuisance machine conductive fiber structural behaviour is ground
Study carefully and the Xi'an anti-static fabric development [D]: Xibei Textile Engineering College, 2005.].
China studies intensively to conductive fiber and gropes to start late, and after the 1980s, grinds to conductive fiber
Study carefully just relatively deeply, the conductive fiber materials such as antistatic polypropylene fiber, antistatic acrylic fiber and electroconductive nylon of independent research are at that time
It appears one after another, extreme enrichment has filled up the blank that China develops conductive fiber and applies.Now, leading as functional material
Electric fiber is by domestic and international expert's extensive concern, although its preparation cost is high, complex manufacturing technology, since it is in civilian clothes
Important function on dress and electronic field, it is believed that its application prospect will be a piece of light.
Carbon nano tube structure and performance: the unique structure of carbon nanotube makes it have the unexistent particularity of other carbon crystals
Can, in addition to corrosion-resistant with graphene, heat-resisting, biocompatibility is excellent etc., performances, electricity and mechanical property are also particularly pertinent.
The excellent reason of electric property be on its molecular structure each carbon atom have not pairs of electronics be located at perpendicular to
On the π track of synusia [Jiang Yuchun utilize carbon nano-tube modification fibroin material research [D] Southwest University, 2014].Have
Studies have shown that theoretical calculation and actual test for the electric conductivity of carbon nanotube the result shows that: due to the difference of structure, carbon
Nanotube is likely to be conductor, it is also possible to be semiconductor [Ebbesen T W, Lezec H J, Hiura H, et
al.Nature,1996,382:54.]。
Times is changing changes, and economy is developing, and the living standard of the mankind increasingly improves, aesthetical standard also increasingly diversification,
And natural fiber either kind or in terms of it is all restricted, be not enough to fully meet market needs.And ramie is fine
Dimension is used as reproducible natural fiber, and its yield is big, can be for full throughout excellent properties that are wide, while having relatively more
The composite material of sufficient social demand provides matrix.
