Description
Technical field
The invention belongs to textile technology field, specifically, is related to a kind of flame retardant viscose fiber and preparation method thereof.
Background technology
Viscose rayon refers to the alpha-cellulose extracted from the cellulosic material such as timber and plant straw, processed into spinning
Stoste, again through staple fibre made of wet spinning, be a kind of regenerated celulose fibre.The moisture percentage of viscose rayon meets human body
The physiological requirement of skin, have it is smooth it is nice and cool, ventilative, antistatic, dye the characteristic such as gorgeous.
Got over the improvement of people ' s living standards with the enhancing of people-oriented awareness of safety, the fire resistance of fibre
To be more concerned by people.There are many countries and regions to formulate product standard, it is specified that the vehicles, public place,
Some fibres that old man, children etc. use must possess fire resistance.With the development of fire resistance fibre technology, further
Fire resistance fibre is asked to have better performance in environmentally protective, heatproof, beneficial to textile process, comfort etc., to meet society's hair
The needs of exhibition.
The preparation of flame retardant viscose fiber mainly has three kinds of methods at present, is that graft copolymerization, mechanical mixture and coating are inhaled
It is attached.Graft copolymerization is that the monomer with fire retardancy is linked into the macromolecular of cellulose；Mechanical mixture is spun in viscose glue
Fire retardant is added in silk liquid；Coating absorption is that fire retardant is adhered to viscose rayon surface by means of the effect of adhesive.Wherein
Based on being produced with mechanical mixing, the fire retardant that uses is with phosphoric acid ester organic fire-retardant and silicates inorganic combustion inhibitor shape
Into industrialization, but it is the shortcomings that the fire resistance fibre of both the above fire retardant production, phosphorous flame-retardant fiber is released a large amount of in burning
Poisonous dense smoke, it is not environmentally friendly enough, and easily make one to suffocate.Fire retardant cost is very high, and product is mainly used for the extraordinary neck such as army, fire-fighting
Domain, big in civil field popularization and application difficulty, development prospect is simultaneously pessimistic.Silicon systems fire resistance fibre is poor there are alkaline resistance properties, washing
Fire-retardant composition loss is more, and there are larger limitation for popularization and application.
In view of this, it is special to propose the present invention.
The content of the invention
The technical problem to be solved in the present invention be to overcome the deficiencies of the prior art and provide a kind of flame retardant viscose fiber and its
Preparation method.
In order to solve the above technical problems, the present invention is using the basic conception of technical solution：
A kind of preparation method of flame retardant viscose fiber, including dipping, experienced, yellow, dissolving, filtering, deaeration, spinning, water
Wash, the process of desulfurization, wherein, in any process before be dissolved into spinning, sodium metasilicate is added into viscose solution, mixing is equal
It is even.
Preferably, in spinning process, aluminum sulfate is added in spinning bath or/and two baths.
In the prior art, it is same using certain being added to together after mixing sodium metasilicate and sodium aluminate solution before spinning
In process, there are following drawback for it：
1st, sodium metaaluminate easily and carbon dioxide reaction, is needed to be deployed into solution in commercial process and reused, and is somebody's turn to do
Solution can react generation aluminum hydroxide precipitation with the carbon dioxide in air, cause the filtration difficulty of viscose solution；
2nd, viscose solution is the product of carbon disulfide and alkali cellulose, wherein comprising a kind of side reaction product NaHS, and
NaHS+NaAlO2+H2O=Na2S+Al(OH)3↓, aluminum hydroxide precipitation can be equally generated, causes viscose solution filtration difficulty or stifled
Fill in spinning filter core or block spinneret orifice.
And the difficulty of viscose solution filtering can be aggravated if both materials are added at the same time in a certain same processes, and
And larger amount of sodium metasilicate and sodium metaaluminate are needed, cause material waste.
Technical scheme is using sodium metasilicate, aluminum sulfate, and substep is added in viscose solution in different processes,
The viscose rayon that can not only make to be prepared has good fire resistance, also overcomes above-mentioned viscose solution filtration difficulty
The defects of, make preparation process more controllable, easy to operate, while save material.
The present invention adds aluminum sulfate in spinning bath or/and two baths, can be to avoid obtained sial mixed gel material resistance
Combustion agent is lost in washing step and wastes fire retardant, influences flame retardant effect.
Preferably, the addition of sodium metasilicate is with SiO2It is calculated as 16~35% of first fibre weight in viscose solution；
The addition of sodium metasilicate is with SiO2Be calculated as first fibre weight in viscose solution reach 16% can reach it is preferable fire-retardant
Property, in the range of 16~35% additions, preparing the fire resistance of the flame retardant viscose fiber of gained increases and improves with content, when
When addition is 35%, anti-flammability oxygen index (OI) can be up to more than 33%, and performance is optimal, if addition is more than 35% fire-retardant oxygen index (OI)
Increase less.
Preferably, the modulus of the sodium metasilicate is 1~3.5；

Experimental study shows, if it exceeds 20%, gel easily occurs in viscose solution for the dioxide-containing silica of the sodium metasilicate
Phenomenon, and if dioxide-containing silica has a great influence the composition of viscose glue, effective composition cellulose contains in viscose glue less than 12%
Amount is reduced, and alkalinity is low, and viscosity is too low, and spinning technique cannot be optimal state.
Preferably, the temperature that sodium metasilicate adds viscose solution is 20~25 DEG C.
Researcher has found to add sodium metasilicate in viscose solution in 20~25 DEG C of temperature ranges, contributes to viscose rayon
Surface forms uniformly firm sial mixed gel fire retardant matter, and more resistant to washing and alkali cleaning.
Preferably, concentration of the aluminum sulfate in spinning bath or two baths is 5~50g/l.
Preferably, the viscosity of viscose solution is 35~49s, and first fibre content is 8.5~10%, alkalinity for 4.5~
5.8%, degree of ripeness is 8~11ml.
It is highly preferred that the viscosity of viscose solution is 40~45s, first fibre content is 8.5~9.5%, alkalinity for 4.8~
5.5%, degree of ripeness is 9~10ml.

340g/l, aluminum sulfate are 5~50g/l；
The composition of two bath is 5~30g/l of sulfuric acid, 5~50g/l of aluminum sulfate.
It is highly preferred that the composition of two bath is 15~28g/l of sulfuric acid, 20~40g/l of aluminum sulfate, it is most preferably sulfuric acid 25
~28g/l, 25~38g/l of aluminum sulfate.
The composition of above-described two bath coordinates the overall preparation process of the present invention, makes viscose rayon shaping more preferable, helps
In lifting fire resistance.
Another object of the present invention is to provide a kind of flame retardant viscose fiber, which uses according to above-mentioned interior
Hold any one described preparation method to obtain.
A further object of the present invention is to provide a kind of flame retardant viscose fiber, and the flame retardant viscose fiber is included by silicic acid
