Description
Technical field
The present invention relates to a kind of hollow speed heat warm-keeping cellulose fiber and preparation method thereof, specifically, be related to it is a kind of with
Cellulose fibre is matrix, the slurry with heating, heat-preserving function is added in spinning solution, the tool being prepared into through wet spinning
There are hollow structure, the health fiber of speed heat heat-preserving function, belong to textile technology field.
Background technology
Traditional insulation garment outward appearance is thick and heavy, fluffy too fat to move, not only lacks aesthetic feeling, and be unfavorable for the activity of body.With
The improvement of people's living standards and the progress of science and technology, requirement more and more higher of the people to clothes, not only comfortably, and attractive in appearance
It is generous.Warming is one of major function of clothes, and light, good warmth retention effect dress material can not only resist cold, and meet
People are to beautiful pursuit, therefore demand is increasing.
Thermal fiber is divided to actively warming and passive warming two kinds.Passive thermal fiber can only prevent or reduce merely Studies of Human Body Heat
Amount is scattered and disappeared, and light passive thermal fiber is based on doughnut, and hollow layer can store part still air, and barrier is extraneous to tremble with fear
It is cold.Positive thermal fiber is will to be added with the functional material that can absorb extraneous electric energy, chemical energy, biological energy source, solar energy etc.
Into fiber.Research at present on thermal fiber is more, but by actively it is warming and it is passive it is warming combine have it is dual
The cellulose fibre research of warming effect is less.
The B of Chinese invention patent CN 102660792 provide the technique that a kind of solvent method prepares sunlight heat accumulation thermal fiber,
" CN 101580969 " provides a kind of method that viscose process prepares heat accumulation thermal fiber to Chinese invention patent Publication No..This two
Individual patent is all that zirconium carbide is added in cellulose solution, carries out blending wet spinning.Although with warming effect, needing
Heat is absorbed under given conditions, and nano-zirconium carbide powder energy absorbing wavelength is less than 2 μm of high-energy ray, and reflection wavelength
Low energy ray more than 2 μm, can generate heat, it is impossible to store heat under sunshine irradiation.
The B of Chinese invention patent CN 104389043 provide a kind of hollow warming heat generating fiber of polycaprolactam and its added
Work method, is that, by polycaprolactam heating master batch and polycaprolactam section progress co-blended spinning, the hollow heating prepared gathers
Caprolactam preoriented yarn carries out fluffy crimpiness processing and prepares final thermal fiber.Although the fiber has preferable guarantor
Warm property, but belong to synthetic fibers, sucting wet air permeability is poor, wears uncomfortable.The A of Chinese invention patent CN 101089256 are provided
A kind of preparation method of doughnut cellulose fiber, although the degree of hollowness of preparation is higher, but the fiber can only have passive warming effect
Really, it is impossible to carry out active heat generating and retention.
The content of the invention
The problem to be solved in the present invention is that there is provided a kind of hollow speed heat is warming for above present Research and technology not enough

Under, dispersant is added in deionized water, nano level speed heat powder is then slowly added into, and adds defoamer, 1500~
Disperse 10~30 minutes under 3000rpm, add grinder and be ground to 2 μm of slurry particle diameter D90 ＜；
The dispersant of described speed heat slurry is preferably neopelex, calgon, polyethylene glycol, and silane is even
Join one kind in agent, addition is 0.5~1.5wt% of slurry；
To keep the stability of speed heat slurry, thickener is added in decentralized system, addition is 0.5~1.5wt% of slurry,
Preferably it is sodium alginate, microcrystalline cellulose.
The addition of the defoamer is the 3-4.5 ‰ of slurry.
The preparation method of described doughnut is：Addition causes empty agent in cellulose solution, and addition is the 5 of alpha cellulose
~10wt%, adds slow forming agent in the cellulose solution of dissolving, and addition is 2~3wt% of alpha cellulose；
Described to cause empty agent to be preferably sodium carbonate, sodium acid carbonate, slow forming agent is preferably polyethylene glycol, fatty amine；
The preparation method, including co-blended spinning, are filtered to the speed heat slurry of preparation with filter, are by being injected before spinning after deaeration
System is added in spinning glue, and the addition of speed heat slurry is 0.5-3.0 of the effective content to alpha cellulose of speed heat material
wt%；
The spinning, 28-40 DEG C of coagulation bath temperature, sulfuric acid 90-95g/l, sodium sulphate 320-330g/l, zinc sulfate 35-40g/l.
Positive heating system two of the present invention by the hollow structure with passive warming effect with adding exothermic material heating
Person combines, and not only adds exothermic material, and makes hollow, and hollow structure can include substantial amounts of still air, not only
Extraneous cold can be separated, and it is more slim and graceful, warming effect can be increased.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
（1）Fiber prepared by the present invention is post-treated, drying obtains hollow speed heat cellulose fibre, and degree of hollowness is 20-50%, will
Conventional cellulosic fibers and hollow speed heat warm-keeping cellulose fiber carry out thermal property contrast test, with reference to light absorbs heat-insulating property
Test method（BQE A 036-2011）, it is found that the speed heat warm-keeping cellulose fiber prepared by the technical program is more fine than common viscose glue
