Description
Technical field
The invention belongs to Blood index fibre technology fields, and in particular to a kind of preparation of native blood spot wiping fiber
Method.
Background technique
Either general surgery, hematology or dialysate chamber or operating room, be easiest to encounter in hospital is exactly blood
The problem of spot, hematology is branch's primary treatment hemopoietic system of internal medicine.Hematology can also be many non-blood diseases
Haematological involvement professional sex service is provided and carries out multinomial engineering test.Haemodialysis is acute or chronic renal failure patient
One of renal replacement therapies mode.It by by internal blood drainage to external, through one by being formed without several hollow fibres
In dialyzer, blood electrolyte solution (dialyzate) similar with concentration containing body is inside and outside hollow fibre one by one, by more
Scattered, ultrafiltration, absorption and convective principles carry out mass exchange, remove intracorporal metabolic waste, maintain electrolyte and acid-base balance；Together
When remove excessive moisture in vivo, and the whole process of the blood recovery by purification is known as haemodialysis.
Due to being gnotobasis when taking blood or operation, cannot be wiped in time after many blood outflows, through after a period of time
Afterwards, blood spot very difficult cleaning and wiping after solidification, it is therefore desirable to which a kind of blood spot cleans adsorbing fiber cloth, can be with
Mitigate the burden of hospital nurse and cleaning worker.
Luffa is the vascular bundle of cucurbitaceous plant sponge gourd ripening fruits.Summer, Qiu Erji fruit maturation, pericarp turn yellow, are interior
Portion is picked when withered, removes crust and pulp, is cleaned, is dried, and seed is removed.Saponins, sponge gourd bitter taste in sponge gourd
The particular matters such as matter, lymphatic temperament, wood glue, citrulling, xylan and interferon have certain special role.The present invention uses silk
Melon network is modified as basic fiber, and to the fiber in luffa, has obtained a kind of luffa absorption containing protease
Fiber cloth can achieve the purpose of lysed blood spot.
Papain (Papain), also known as papain are a kind of proteolytic enzymes.Papain is papaya
(Carieapapaya) a kind of low specificity proteolytic enzyme contained in, universally present in the root, stem, Ye Heguo of papaya
In reality, wherein content is most abundant in immature milk.The activated centre of papain contains cysteine, belongs to sulfydryl egg
White enzyme, it has the characteristics that, and enzyme activity is high, thermal stability is good, natural safe and healthy, therefore in food, medicine, feed, daily use chemicals, skin
The industries such as leather and weaving are used widely.
Soapberry pericarp sesquiterpene glucoside containing soapberry, sapindoside, Sapindus saponin(e etc., can manufacture " naturally without public affairs
Evil abluent " is used for daily washing.The fruit of natural plant Chinese soapberry tree, by manually shining system, peeling, the pure fruit then obtained
Skin can be used directly to extract its effective ingredient saponin(e, manufacture natural nuisance-free cleaning supplies soapberry soap cream Sapindus handmade
Soap etc..In traditional sense, all it is to come out the saponin extraction of soapberry, is added in cleaning product, it is not only at high cost in this way,
And its effect is disposably, cannot to reach the slow releasing function of saponin(e.For this purpose, the present invention provides a kind of scourings of blood spot
The preparation method of adsorbing fiber cloth, the blood spot, which cleans adsorbing fiber cloth, can quickly dissolve the blood spot after solidification,
It is dissolved rapidly, as long as saving suitably, it can be used repeatedly more than 100 times or more for the protease in fiber.
Summary of the invention
In order to solve the problems, such as not having in hospital a kind of blood that easily can wipe i.e. to wipe fiber, inventor's root
The characteristics of according to blood, combines several natural extracts, is prepared for a kind of natural blood spot wiping fiber, described natural
Blood spot wipe fiber the preparation method is as follows:
1) by luffa KMnO4Clear water rinses after aqueous solution soaking, and dries and obtain dry luffa；
2) it is that 0.1~0.5% (m/V) NaOH aqueous solution is mixed with beating processing by soapberry pericarp and concentration, obtains no trouble
Sub- pericarp slurries；
3) dry luffa is put into 0.5~12h of immersion in soapberry fruit latex liquid, by its pH value tune after the completion of immersion
It is whole to 3.0~6.0；
4) pectase is added in luffa soak, enzymolysis processing is carried out to it；
5) luffa after enzymatic hydrolysis is dried, obtains dry modified loofah sponge；
6) dry modified loofah sponge is placed in Papain enzyme aqueous solution and is impregnated；
7) ethanol solution of furfuryl alcohol is added in the Papain enzyme aqueous solution for being equipped with modified loofah sponge, so that pawpaw egg
White enzyme is precipitate into loofah fiber gap from luffa soak；
8) modified loofah sponge after washing with water reaction is placed in 30~55 DEG C of environment and air-dries, obtains the natural blood
Liquid spot wipes fiber.
Further, described to use KMnO4Aqueous solution soaking specifically: use concentration for 0.1~1.5% KMnO4Aqueous solution
Impregnate 10~30min.
Further, the concentration of the NaOH aqueous solution is 0.1~0.5%.
Further, the solid-liquid ratio of the soapberry pericarp and NaOH aqueous solution is 1:3~1:20.
Further, the condition of the pectinase enzymatic hydrolysis are as follows: 3~36h is digested under conditions of 40~50 DEG C of temperature.
Further, the additive amount of the pectase is the 1~3% of dry luffa quality.
Further, the concentration of the Papain enzyme aqueous solution is 5~10%.
Further, the modified loofah sponge and Papain enzyme aqueous solution solid-liquid ratio (m/V) are as follows: 1:1~1:3.
Further, the ethanol solution of the furfuryl alcohol is the ethanol solution for the furfuryl alcohol that furfuryl alcohol content is 30~40%.
Beneficial effect
The present invention, in the case where not destroying original loofah fiber, is modified loofah fiber by being modified
Processing, modified loofah fiber hardness are slightly below unmodified loofah fiber, main cause be after soda acid is handled,
Its few fibers is hydrolyzed, but introduces natural sapindoside, sapindoside in the present invention in original loofah fiber
Major surfactant ingredient is triterpene saponin (I), sequiterpene glycoside (II), fat oil and protein, is a kind of natural
Nonionic surface active agent, all-natural product, no added any artificial synthetic detergent, essence, pigment and preservative.It can be with
Easily remove various dirty things.Another big special place of the present invention is exactly that pawpaw egg is enclosed in loofah fiber hole
White enzyme, then by the precipitation and solidification of furfuryl alcohol ethanol solution so that the papain in loofah fiber hole have it is slow
Effect is released, nonexpondable purpose is reached.
After loofah fiber prepared by the present invention impregnates 6 days in water it can be seen from experimental data, enzyme activity is continuous
It reduces, but decrease speed is very slow, if not having to furfuryl alcohol ethanol solution is precipitated papain, after impregnating 1h, pawpaw egg therein
White enzyme is all soluble in water, it is seen then that papain is fixed on fibrous inside by the method for the present invention, dirty when wiping blood using it
When stain rubbing friction, papain is oozed out due to squeezing from fibrous inside, achievees the purpose that lysed blood spot.
Luffa blood wiping fiber hemolyzing effect prepared by the present invention is good, carries saponin(e and protease, as long as it is light to get wet
It dabs and wipes and solid blood spot can be wiped, wiping effect is good, and long using the time, and it can be used repeatedly.It avoids
Blood spot cleans difficult problem in hospital, in addition to this it is possible to it is used to clean the spot of any protide, such as:
Milk spot etc..
It is natural extract or crude that the present invention, which prepares raw material, and preparation process is produced without poisonous and harmful substance
Raw, safety and environmental protection has very high economic value and use value.
