Method is, using pulp as raw material, impregnated, squeezed, being crushed, aging, yellow, dissolving, maturation, filtering, the processes such as deaeration.Slurry
The dregs of rice are impregnated through a concentration of 18% or so sodium hydrate aqueous solution, and cellulose is made to be converted to alkali cellulose, and hemicellulose dissolution gathers
Right part declines；Extra lye is removed through squeezing again.Block-like alkali cellulose becomes loose after being crushed on pulverizer
Flock, since surface area increase makes later chemical reaction uniformity improve.Alkali cellulose aoxidizes under the effect of the oxygen
Cracking makes average degree of polymerization decline, this process is known as aging.Alkali cellulose is reacted with carbon disulfide after aging and generates fiber
Plain xanthate acid claims yellow, and the hydrogen bond between macromolecular is made further to weaken, and due to the hydrophily of yellow acid group, makes cellulose xanthate
Solubility property in sig water greatly improves.Solid cellulose xanthate acid is dissolved in sig water, is viscose glue.Just it is made
Viscose glue is because of viscosity and salt figure is higher is not easy to shape, it is necessary to placing certain time at a certain temperature is known as maturation, makes in viscose glue
Sodium cellulose xanthate gradually hydrolysis and saponification, esterification degree reduce, viscosity and to electrolyte effect stability also with change.
Deaeration and filtering should be carried out after maturation, to remove bubble and impurity.It is specific as follows：

In general, graphene-structured and the non-oxygen member of non-carbon can be introduced in the above-mentioned multiple links for preparing viscose
Element, such as before crushing or before aging either before yellow or before maturation.Will not usually it filter or take off
Step is steeped to introduce later.The present invention introduces preferably after maturation, before filtering, and inventor has found, graphene is at this moment being added
The mixing efficiency higher of structure and substance containing non-carbon nonoxygen element, can be reduced to more than half, usually by incorporation time
One third can be reduced to.
In the present invention, dispersion is first preferably made in graphene-structured and substance containing non-carbon nonoxygen element, then
The dispersion solution is uniformly mixed with viscose.Preferred dispersion solvent is water.It is preferred that by the compound containing graphene-structured
The dispersion that solid content is 0.1~10% is made.
One preferred mode is that first the compound containing graphene-structured is dispersed in for dissolving cellulose yellow acid
In the dilute alkaline soln of ester, the cellulose i.e. cellulose xanthate of yellow is added after scattered.The advantage of this method is：No
Water must be in addition introduced because graphene-structured is introduced, cellulose is combined with graphene-structured upon dissolution, is mixed
More uniformly.In this embodiment, when graphene-structured being scattered in dilute alkaline soln and cellulose xanthate is being added
Later, it is not necessary to long agitation, and short time stirring is being carried out after overcuring, graphene-structured can be greatly improved
Dispersion efficiency.
Next, filtering and carrying out spinning after deaeration, desulfurization, wash, oil and dry and glued to get to final
Glue fiber.These belong to conventional method, are not described in detail herein.
Specifically using corncob as raw material, it is made after dipping alkalization, squeezing, crushing, aging, yellow, dissolving, maturation and contains admittedly
For 8% viscose；Embodiment 1-8 and comparative example 1-3 is obtained into the raw material of graphene-containing structure with the water-dispersed of 5 times of quality,
Then graphene-structured dispersion liquid is blended with viscose, is stirred 1 hour with homogenizer, forms blend solution, graphene-containing
The compound dosage of structure is 0.1%, 3%, 5% and the 10% of cellulose quality.Then filtering, deaeration are passed through spinning, are taken off
Functional viscose fiber is made in sulphur, washing, drying.Wherein, the composition of coagulating bath：Sulfuric acid 105g/l, sodium sulphate 200g/l, sulphur
Sour zinc 12g/l.The far infrared performance and anti-microbial property of functional fiber are detected, examination criteria is as follows：
Wherein, infrared detection data foundation：Through national textile fabrics Quality Supervision and Inspection Center, according to FZ/T64010-
2000 methods of inspection are tested；
Antibacterial detection data foundation：Through national textile fabrics Quality Supervision and Inspection Center, according to GB/T20944.3-2008
The method of inspection.
Testing result：
The raw material of graphene-containing structure and non-carbon nonoxygen element that Examples 1 to 8 and comparative example 1~2 are prepared is added.
When addition is 1%, functional viscose fiber is prepared：
When addition is 3%, functional viscose fiber is prepared：
When addition is 5%, functional viscose fiber is prepared：
When addition is 10%, functional viscose fiber is prepared：
After graphene-containing structure and non-carbon nonoxygen element being introduced during preparing regenerated celulose fibre, it is also necessary to pass through
The subsequent process steps of weaving, thus non-carbon nonoxygen element content with introduce the substance carrier or mixture or compound not
It is corresponding identical proportional relationship.For example, the form by carbon nano-structured compound introduces graphene-structured and non-carbon
Nonoxygen element, when carbon nano-structured compound addition is the 1wt% of fiber, non-carbon nonoxygen element content accounts for the 0.2 of fiber,
When addition is the 3wt% of fiber, non-carbon nonoxygen element content accounts for the 0.5wt% of fiber.Therefore, contain graphene in fiber
The type and content of structure and non-carbon nonoxygen element play the role of the far infrared performance and anti-microbial property of fiber key.
Plant itself is can be seen that there are many trace elements by above example and comparative example, utilizes plant itself
The substance containing graphene-structured and trace element is directly prepared, it is more equal so that each ingredient in product disperses
It is even, such as trace element, it then can achieve the effect that when being combined with substances such as high molecular materials more excellent；And lead to
Later the phase introduces trace element, and mixing more even results just can be more apparent, and effect is poorer than the effect naturally mixed
Some.
