Description
Technical field
The invention discloses a kind of preparation method of viscose staple fibre, belong to textile material technical field.
Background technology
Viscose staple fibre obtains as a kind of common and important chemical raw material in industrial production and daily life
It is extensive to use, but its combination property such as antistatic property etc. has much room for improvement.
FRC has inorganic FRC, the major class of organic fire-resisting viscose rayon two.Organic fire-resisting viscose glue is fine
For the inorganic fire-retarded viscose rayon of peacekeeping silicon nitrogen system because being influenceed by fire retardant price is high, its price is also expensive, make its application market by
To considerable restraint.And the inorganic fire-retarded viscose rayon produced with silicates fire retardant, not only fire retardant is cheap, fire-retardant effect
Fruit is good, also have low cigarette during burning, without poison gas, do not melt the good characteristics such as drippage, thus its application prospect is very good.It is but raw
To ensure that its efficient flame retardant effect need to add a large amount of silicate fire retardants when producing silicate inorganic fire retardant viscose short filament, cause
The dry fracture strength of finished fiber, wet breaking strength are relatively low, it is impossible to meet downstream textile mills spinning requirement, be only capable of producing non-woven
Dry goods product, application field are very limited.
Secondly, one of bacteriostasis property evaluation viscose staple fibre combination property.At present, antibacterial chopped fiber preparation method mainly has
Two kinds, when finishing method, second, fiber blend is modified method.Finishing method is to develop earliest and continue up textile so far
Antibacterial processing method, this method is with the solution containing antiseptic or finished fiber and fabric are impregnated resin or coating processing,
So as to assign fiber and antibacterial fabric activity, easy to operate and alternative antiseptic scope is wide, but finishing method obtains
The anti-microbial property persistence of antibacterial fabric is poor, in general by the antibacterial fabric that afterfinish method is processed in washing time
Afterwards, antibacterial functions almost without.Fiber blend is modified method compared with finishing method, due to the equal Uniform distributions of antiseptic in the fibre
Therefore washing resistance performance is better than the fiber and fabric obtained through antibiotic finish, antibacterial efficacy is more longlasting.In addition, the process of final finishing at present
The antiseptic of addition is mainly inorganic antiseptic and organic antiseptic.Wherein inorganic antiseptic mainly there is antibacterial to make
Metal inorganic salt and antibacterial zeolite particles, inorganic antiseptic contain contents of many kinds of heavy metal ion, not only to the hand of textile after addition
Sense and wearing comfortable have a great impact, and easily by being good for contact human skin and the influence human body that is absorbed by the body
Health.
Therefore, viscose staple fibre antistatic property, fire resistance, bacteriostasis property and mechanical property are improved, turns into its popularization
With applied to broader field urgent problem to be solved.
The content of the invention
The present invention solves the technical problem of：It is antibacterial for traditional viscose staple fibre antistatic property, fire resistance
A kind of the problem of performance and bad mechanical property, there is provided preparation method of viscose staple fibre.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）By chitosan and biogas slurry in mass ratio 1：7~1：10 mixing, ferment at constant temperature, concentrated by rotary evaporation, chitosan concentration must be activated
Liquid；
（2）By silver nitrate and calcium nitrate in mass ratio 2：1~3：1 mixing, and add the nitric acid of 0.6~0.8 times of silver nitrate quality
The water of 30~40 times of aluminium and silver nitrate quality, is stirred, obtains mixed liquor；
（3）By chitosan concentrate and mixed liquor in mass ratio 5：1~8：1 mixes, and after stirring reaction, must activate chitosan mixing
Liquid；
（4）By pulp and sodium hydroxide solution in mass ratio 1：4~1：7 mixing, impregnate, and filtering, obtain alkalization pulp；
（5）By alkalization pulp through squeezing, crush, obtain crushing pulp, chitosan mixed liquor will be activated and crush pulp in mass ratio
2：3~2：5 mixing, and the nano silicon for crushing 0.08~0.10 times of pulp quality is added, sonic oscillation, obtain chitosan slurry
Dregs of rice mixture, by chitosan pulp mixture through experienced, after yellow, obtain spinning solution；
（6）By spinning solution after spinning-drawing machine spinning, drawing-off in drafting machine is added, obtains precursor, by reducing agent and water in mass ratio
1：4~1：8 mixing, obtain treatment fluid, by precursor and treatment fluid in mass ratio 1：8~1：12 mixing, after ultrasonic immersing, then to processing
Ammonia is passed through in liquid, continues to react, obtains processing precursor, by processing precursor washing, dries, obtains viscose staple fibre.
Step（2）Described silver nitrate, calcium nitrate and aluminum nitrate are that analysis is pure.
Step（3）The pulp is wood pulps, any one in bamboo pulp or Cotton Pulp.
Step（6）Described reducing agent is any one in zinc powder or vitamin C.
The beneficial effects of the invention are as follows：
（1）The present invention makes addition activate chitosan when preparing viscose staple fibre, and first, chitosan is after activated, active group
Group's number increases, and can react and combine with the pulp small molecule after alkalization, so that the molecule between viscose staple fibre combines
Power strengthens, and is improved the mechanical strength of product, and secondly, activation chitosan is living after being added in viscose staple fibre system
Change chitosan molecule and can be adsorbed on viscose staple fibre molecular surface, and because chitosan has the ability of chelated metal ions,
So that metal ion can be in viscose rayon adsorption, while disperseed well；
（2）The present invention adds silver nitrate in the chitosan mixed liquor that viscose staple fibre uses is prepared, and silver ion can be gathered by shell
Sugar chelating, and then viscose staple fibre surface is evenly distributed on, moreover, after reducing agent is added, silver ion can be from chelating systems
In be replaced out, equally distributed elemental silver is formed in the system of chitosan and viscose staple fibre, so that product is anti-
Antistatic property and bacteriostasis property are improved；
（3）The present invention adds calcium nitrate and aluminum nitrate in the chitosan mixed liquor that viscose staple fibre uses is prepared, and
Add nano silicon and ammonia in post-processing into viscose staple fibre system, the calcium in the calcium nitrate and aluminum nitrate of addition
Ion and chlorion can be chelated by chitosan molecule, be evenly distributed on viscose staple fibre surface, after ammonia is passed through into system,
The calcium ion and aluminium ion of chelating can gradually become hydroxide and be present in system, run into high-temperature condition meeting in use
The raw oxide adsorbent that is dehydrated into viscose staple fibre surface, caused moisture can effective blocking oxygen, play fire retardation, and shape
Into oxide can densification be covered in fiber surface, play heat-insulating flame-retardant effect, also, add nano-silica surface live
Property it is higher, after being added in system, hydration reaction can occur with the hydroxide of formation, form hydrated product, so as in viscose glue
Chopped fiber surface forms one layer of hydrated gel diaphragm with some strength, the mechanical performance of product is further increased
By force.
