Description
Technical field
The present invention relates to fibre modification processing technique field, in particular to one reduces lyocell fiber
The method of cellulose fiber fibrillation tendency.
Background technology
The appearance of chemical fibre greatly meet people to clothing, decoration and the demand of fabrics for industrial use, but
Along with the minimizing of world oil storage level, the exploitation of the synthetic fibers with oil as primary raw material also will be limited
System.The shortage of non-renewable textile raw material forces the focus that utilizes of people to turn to reproducible textile raw material, and
And along with people's concern to environmental conservation, with renewable natural resources for development of raw materials staple fibre increasingly
Come into one's own.
The production of the Lyocell fiber polyhydroxy with wood pulp as raw material, on this technology utilization NMMO and cellulose
Hydrogen bond can be produced and make the characteristic of cellulose dissolution, wood pulp, water and solvent NMMO be heated, by cellulose slurry
Dissolve (physical property dissolving), obtain the spinning liquid (viscosity up to thousand of pools about) of thickness, then with wet-dry change
Spinning process spinning forms.The NMMO separated out in spinning coagulation bath, rinse bath can reclaim, refine, molten
The agent response rate is up to more than 99%.Owing to eliminating viscose rayon production in the production process of Lyocell fiber
Middle a large amount of waste liquids, waste gas and the waste residue produced because adding the various chemical reagent such as Carbon bisulfide, with safety
Chemicals NMMO (toxicity is lower than ethanol) is solvent, and whole production system forms closed loop Recovery and recycle
System, does not has trash discharge, environmentally safe.
Owing to Lyocell fiber product is the cellulose of 100%, can within a short period of time complete biodegradable be
Inorganic matter CO2 and H2O, participates in the material circulation of natural ecosystems, again to environment without any pollution, quilt
It is described as " green fiber " of 21 century.Coming out of Lyocell fiber provides excellent former for producing textile
Material, authoritative institution of the world predicts, Lyocell fiber will become cotton of continuing, hair, silk, numb four big natural fibers it
After the fifth-largest fiber.
Lyocell fiber has skin-core structure, and its cortex is two-layer composite, and sandwich layer is by highly crystalline and takes
To tassel shape giant fibril and unformed area composition.Because cortex is the thinnest, Lyocell fiber almost all is sandwich layer
Structure.Height-oriented and the mutual lateral connection of Lyocell sandwich layer giant fibril is the weakest, unformed area quilt
Water or sodium hydroxide solution infiltration can occur acutely to expand later, weaken the contact between fibril further.This
Structures shape Lyocell fiber under conditions of the hygral expansion or alkali hygral expansion state and mechanical external force effect,
Easily produce fibrillation phenomenon.This characteristic utilizing Lyocell fiber can produce imitative peach-skin fabrics.
But, under many circumstances, fibrillation brings the most unnecessary fiber crops can to again production and processing person and consumer
Tired.
At present, solve lyocell fiber cellulose fiber to be prone to the approach of fibrillation and mainly fiber is cross-linked
Post processing realizes, or the fabric being made into fiber carries out cross-linking post processing and realizes.Wherein publication number
The patent report of CN1147281A with N-methoxyl group resin and zero formaldehyde resin as cross-linking agent, citric acid is for urging
Agent, with cellulose base fiber fabric haptoreaction, reduces the fibrillation tendency of fiber in fabric.Invention number
The patent report of the CN103306136A oligomeric polyprotic acid with molecular weight as 400-1000 and C2~C6 polyprotic acid
The cross-linking agent combined, reacts with cellulose fibre, and the anti-Fibrillation Properties of fiber is had obvious effect.
The patent of invention CN103046146A reports and dissolves cellulose fiber by the ionic liquid of zwitterion composition
Dimension, has obtained, by the spinning of dry-jet wet-spinning, the cellulose fibre that anti-Fibrillation Properties is excellent.But above-mentioned patent
Used in cross-linking agent synthesis loaded down with trivial details, complex process, commercial production difficulty is bigger.
Summary of the invention
The technical problem to be solved is to provide a kind of lyocell fiber cellulose fiber fibrillation that reduces and inclines
To method, it has screened the cross-linking agent being easy to get, and by specific method to lyocell fiber cellulose fiber
Process, thus eliminate defect in above-mentioned background technology.
For solving above-mentioned technical problem, the technical scheme is that
A kind of method reducing lyocell fiber cellulose fiber fibrillation tendency, step is as follows:
(1) lyocell fiber is made to immerse in a kind of aqueous solution containing cross-linking agent, catalyst and penetrating agent;
(2) pretreatment 90-150s, then roasting at 125-135 DEG C at 75-85 DEG C after this fiber being dried
Dry 90-150s, make fiber solidifying crosslinking;
(3) fiber after baking washs 3-7 time with the soft water of 50 DEG C, then with cold soft water washing 1-3
Secondary:
(4) finally fiber is dried at 80 DEG C, i.e. can get antigen fibrillation lyocell fiber cellulose fiber.
In the present invention, in step (1), lyocell fiber can be to pass through the dry state fibre of dried
Dimension, but the hygrometric state fiber of more preferably undried.This hygrometric state fiber not being dried itself has swelling
Property, cross-linking agent, catalyst etc. be more easy to enter fibrous inside, react is in hgher efficiency, and fiber surface
Swelling, the reaction with cross-linking agent is more abundant, and the cross-linked structure of formation is more, can substantially reduce its fibrillation and incline
To.If the most dried dry state fiber, to be then soaked in water a period of time before crosslinking Treatment, make
Fiber is the most swelling.
In the present invention, in step (1), described cross-linking agent is the carbochain twain-aldehyde compound cross-linking agent at C2-C6, excellent
Select Biformyl.Biformyl contains Liang Ge carbonyl group, under the effect of catalyst, it is believed that cellulose divides
Hydroxyl in son reacts with the carbonyl in Biformyl due to acetalation, and thus cellulosic molecule produces
Raw crosslinking, in described solution, every liter contains 60-90g, preferably contains the Biformyl of 70-90g.
In the present invention, in step (1), described catalyst is the one in magnesium chloride, aluminum sulfate or tartaric acid.

Surfactant.The γ cmc of nonionic surfactant is respectively less than 30mN/m, the γ of ionic surfactant
Cmc is at about 40mN/m.Nonionic 1~2 order of magnitude lower than the cmc of ionic surfactant, easily
Form micelle, beneficially emulsifying.Therefore selecting nonionic surfactant to make penetrating agent, inventor is through excessive
Amount test repeatedly proves: when employing penetrating agent is JFC, and concentration in the solution is 1-7g/L, preferably
When being 2-3g/L, the highest with the compatible degree of this technique, it is possible to greatly reduce lyocell fiber cellulose fiber fibril
Change tendency.
In lyocell fiber cellulose fiber of the present invention crosslinking post-processing approach, it is special that the time of dipping does not has
Requirement, is preferably immersed in 5-10min in cross-linking agent solution by lyocell fiber cellulose fiber.Within the range,
Cross-linking agent can be made the most sufficiently and uniformly to be impregnated in cellulose fibre while controlling time cost.
In lyocell fiber cellulose fiber of the present invention crosslinking post-processing approach, the temperature of dipping is the most crucial
Requirement, in order to preferably improve the anti-Fibrillation Properties of lyocell fiber cellulose fiber, control solution temperature is 60-90
DEG C scope, the scope of preferably 60-70 DEG C.At this temperature, solution system is more stable, and then permissible
Preferably protect the self structure of fiber, it is ensured that the physical property of fiber.
