Description
Technical field
The present invention relates to drier, more particularly to a kind of chameleon fibre drier and its manufacture method and purposes.
Background technology
Drier is the damp proof article being in daily use, for example, used in food, medicine or typically hold in hygroscopic packaging,
It can extend the storage life of article using drier or prevent corruption.Drier main Types currently used in the market be silica gel,
Bentonite, molecular sieve, calcium oxide, aluminum oxide and fibrous type drier etc., in addition to fibrous type drier, other drier
Form it is main with graininess or it is powdered based on, then packed again with gas permeability bag, still, such packaging bag is sometimes
Because the quality of packaging is bad or is ruptured by collision, causes drier to leak and pollute article or product, more seriously
Eating by mistake may damage after contaminated food to human body.
In practice, it is therefore desirable to intuitively reflect the drying of drier moisture absorption degree or pack environment by color change
Degree, such drier seldom, most commonly in silica gel add cobalt chloride (being commonly called as blue glue) come what is realized, color by
Blue (maximum dried active) fades to pink (no drier activity).But, studied through external relevant department, cobalt chloride is
Two class carcinogenic substances are listed in, because health of the meeting to the producer, user during the manufacturing process of blue glue or long-term use
Harm is produced, and it is unfavorable to environmental protection, the instruction of its color is more dull in addition, is only limitted to change between blueness and pink, so
Some countries are phased out at present uses blue glue.
The content of the invention
Indicated it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind is selectable
Various colors, harmless, environmentally friendly chameleon fibre drier and its manufacture method and purposes.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of chameleon fibre drier, including high absorption affinity fiber, it is characterised in that adsorbed in described high absorption affinity fiber
Functional auxiliary agent, the function additive is made up of calcium chloride, sodium chloride, polyacrylamide, dye indicator.
One or more of the described dye indicator in methyl orange, methyl red, dimethyl diaminophenazine chloride, bromocresol green.
A kind of manufacture method of chameleon fibre drier, it is characterised in that the manufacture method is comprised the following steps that：
(1) preparation of high absorption affinity fiber
First by raw fibre and the organic compound reaction with key, slough a small molecule, and through being hydrolyzed in alkaline solution and
Carboxylated processing, is made carboxylated product, i.e., high absorption affinity fiber.
(2) functionalization of high absorption affinity fiber
The high absorption affinity fiber prepared is cut into required shape, is then immersed in function additive, the function additive is
Containing calcium chloride, sodium chloride, polyacrylamide, dye indicator solution, make the solute in the abundant adsorbent solution of fiber, then
It is baked to, that is, chameleon fibre drier is made.
Described raw fibre includes wood-fibred, cotton fiber, flaxen fiber, reed, cellulose derivative class hygroscopicity plant
Fiber, described cellulose derivative class hygroscopicity string is modified plant fibers.
The described organic compound with key is acyl class compound, including acrylamide, polyacrylamide, cation
Or PAMA, nonionic acrylamide, polyamide derivative, its solution concentration is 0.5~25 weight %.
Described alkaline solution include sodium hydroxide, potassium hydroxide, calcium hydroxide, liquor natrii hypochloritis, the solution it is dense
Spend for 0.1~40 weight %.
The composition of described function additive is the weight % of chloride containing calcium 3~60, the weight % of sodium chloride 0.1~20, polypropylene
The weight % of acid amides 0.1~15 and weight % of dye indicator 0.001~6, described function additive can pass through hydrochloric acid or lemon
Its pH value is adjusted to 4~6 by acid, and the soak time of described high absorption affinity fiber in function additive is 5~15 minutes.
Described drying temperature is 100~110 DEG C.
The preparation of described high absorption affinity fiber and functionalization are carried out at ambient pressure.
A kind of purposes of chameleon fibre drier, it is characterised in that the drier be used for leather and fur products, case and bag, shoes and hats,
Protection against the tide in textile, clothes, medicine, tealeaves and industrial goods, the storage of daily living article, transportation.
Compared with prior art, the advantage of the invention is that having selected methyl orange, methyl red, dimethyl diaminophenazine chloride, bromocresol green etc.
Dye indicator is used as the color indicator of drier, and has abandoned using this kind of carcinogenic substance of cobalt chloride, passes through one or more
The use of dye indicator, to reflect the moisture absorption degree or degree of drying of drier, the appearance luster of the indicator can be with
The difference of aqueous degree and reversible change, it indicates the change that the scope of color is not limited between blueness and red, may be selected
Color gamut it is very wide.The wettability power of fiber desiccant of the present invention can change according to the change of active ingredient in solution
Become, so as to produce the fiber desiccant of different wettability powers.After the chameleon fibre drier moisture absorption of the present invention, it can be placed in again
Dried in drying oven, or after other method is dried, remove the moisture content of moisture absorption, you can be reduced to original color and
Wettability power, reaches the effect of reuse.
