Description
Technical field
The present invention relates to the equipment of a kind of improved scouring of wool method and enforcement scouring of wool.
Background technology
Hair is one of most important animal fiber of weaving processing use.Natural characteristics such as the feel of Mao Yinqi brilliance, moisture absorption, intensity and drapability and be considered to be better than other fibers.Raw wool must be through the multiple tracks processing procedure before using for weave processing or other purposes.
The raw wool of taking from sheep or other animals comprises the composition that many quilt hair processors are considered as impurity, and these impurity must be removed from raw wool before use basically fully.The kind of the kind of impurity and quantity follower, nutrition, environment and the position of hair on the animal health are different and different.Main impurity is the part that dissolves in solvent that is known as mao fat, protein, water-soluble portion (mainly be sweat salt, be referred to as lanoline), dirt and from the vegetable matter of forms such as the bur in pasture and grass-seed.According to animal situation difference, the carded lap waste can contain the impurity up to 30% (weight), and therefore, before using raw wool being handled is important step.
The first road process that raw wool is prepared comprises removal of impurities, and this process is called scouring of wool.
In traditional scouring of wool, the impurity on the raw wool mainly is a mao fat, dirt, lanoline and protein, is washed off from wool fibre under the effect of water and washing agent.These impurity still are present in the waste water, or are emulsion or suspension (hair fat, dirt, protein), or are solution form (lanoline).This waste water is extracted the fat that can produce impurity such as containing washing agent and lanoline, be known as a mao fat.Traditional scouring of wool method comprises the multipass processing, add various washing agent and consume a large amount of water.Typical scouring of wool device can consume nearly 500,000 liters water every day.Except the big water gaging of needs, also bring and to handle these waste water bring excess contamination with the exempt from customs examination environment problem.Waste water handling problem comprises further cost, and along with the control increasingly stringent to environmental emission, just requires the processing of advanced certain form of row to be discharged in the environment again.
Other impurity that exist in the raw wool comprise herbicide and pesticide, and they need particular processing to remove from the waste water that traditional scouring of wool produced.Any increase of scouring of wool cost generally all will be married again on one's body the consumer, thereby makes hair with respect to other fibers of competing with it that use in the same industry mutually, comprises artificial fibre, the rise on price.
The inventor has developed a kind of scouring of wool method, and the needed water consumption of this method has been compared with the whole bag of tricks of present use significantly and reduced, and this method comprises the effective tool that processes clean hair.
Summary of the invention
A first aspect of the present invention comprises the scouring of wool method of being made up of following steps:
(a) raw wool is handled, made the lipid impurity that exists in the raw wool that partial liquefaction take place at least;
(b) in raw wool, add a kind of material of the lipid impurity that has liquefied in can absorptive hair, step (a) with (b) can implement in any order;
(c) raw wool is mixed with this grease-absorbing material, the liquefied grease impurity of requested number is absorbed in this material; And
(d) material that will absorb fat is separated from raw wool.
A second aspect of the present invention comprises a kind of scouring of wool equipment, and it comprises:
(a) make the lipid impurity that exists in the raw wool that the handling implement of partial liquefaction take place at least;
(b) be fit to accept raw wool and can absorptive hair in the container of material of the liquefaction fat impurity that exists;
(c) make raw wool and above-mentioned grease-absorbing material in this container, realize the instrument that mixes; And
(d) will absorb the instrument that the material of fat is separated from raw wool,
Wherein when raw wool places this container, this handling implement makes lipid impurity that partial liquefaction at least take place, and then, the raw wool in the container is realized mixing under the effect of blend tool with grease-absorbing material, caused before separating, the liquefied grease impurity of requested number is absorbed in this material.
Preferred this processing comprises the heating to raw wool, and more preferably this processing comprises the differential heating to raw wool, so that lipid impurity is heated, and wool fibre and grease-absorbing material are heated substantially, or at least its degree of heat less than lipid impurity.
The liquefaction of lipid impurity occurs in about 50～60 ℃.In order to alleviate the possibility of wool fibre damage, the temperature of wool fibre should preferably be no more than about 70 ℃ during the scouring of wool.In order to realize differential heating, this treatment step preferably includes the radiation heating by microwave energy.Be appreciated that any other can make lipid impurity partial liquefaction at least, and the handling implement that raw wool or grease-absorbing material are heated to lipid impurity uniform temp also can be used for the present invention.
Raw wool is handled and is finished in a container with raw wool and grease-absorbing material are mixed preferably mutually.Do the control that helps the scouring of wool process like this and guarantee fully mixing of raw wool and grease-absorbing material,, and from raw wool, remove so that make the fat of liquefaction be able to contact with grease-absorbing material.Any container that can induce raw wool and grease-absorbing material to mix mutually all is suitable for.The example that is suitable for container comprises cyclone separating chamber, rotary drum and self-conveyor feed.
Be appreciated that grease-absorbing material can add before the treatment step or during handling.In order to implement the appointed condition of this method, this scouring of wool method can be implemented according to intermittence or continuous mode according to specifically.
This grease-absorbing material is bulk material preferably.Being specially adapted to bulk material of the present invention is diatomite.But other materials that can absorb fat also are fit to the present invention to be used.This type of examples of substances comprises that talcum powder, silica, hydroxyapatite, silica gel and other can absorb the bulk material of fat and oil.In view of diatomite is celebrated by force with its water absorbing capacity, be not difficult to expect that other hygroscopic materials also may have fat, fat and the oily ability that exists in the absorption raw wool, thereby also may be applicable to the present invention.
The addition of grease-absorbing material changes with the difference that contains assorted grade and desired scouring of wool degree of raw wool in raw wool.Moreover grease-absorbing material contains hybrid class and degree to what the ratio of raw wool will depend on the liposuction ability of used material and the raw wool of washing.The fat in the raw wool and the character of other impurity and content to the requirement of grease-absorbing material also have shadow to.Be not difficult to expect that the consumption of the required grease-absorbing material of different types of raw wool also is not quite similar.
After the liquefaction of lipid impurity, grease-absorbing material mixes with raw wool, makes lipid impurity be absorbed in this material, thereby removes from wool fibre.It will also be appreciated that other impurity that exist in the raw wool as dirt and vegetable matter, are also associating with liquefaction fat mutually, also will be disposed by the inventive method from fiber.
An advantage of the invention is, do not need to add big water gaging in the scouring of wool process.Yet, be not difficult to expect, contain a certain amount of associated water in the raw wool,
The inventive method has certain adaptive capacity, and therefore, the degree that lipid impurity is removed from raw wool can be regulated.In order to make scoured wool can be processed into textile product efficiently, in raw wool, keep a part of fat usually, be beneficial to the carrying out of processing.The present invention can control the fat amount of disposing by degree of treatment, grease-absorbing material consumption and the mixability of control during the scouring of wool from hair.
The present invention is used for the hair of the suitable form of ownership of method and apparatus of scouring of wool, is not limited to the wool that sheep is produced.For example, the hair that originates from alpaca (South America alpaca), goat and so on also can adopt method and apparatus of the present invention to be cleaned.
Can expect that the wool impurity content particularly comes from the hair of sheep, the difference of the kind of follower and animal grazing habit has very big difference.In Australia, the sheep that the Queensland herds in the area is compared with the sheep that herd in for example colder Australian south, and it is less that the raw wool that is produced contains lipid impurity, and dust and dirt are then more.And baby lamb is wanted much less than the percentage of impurity that adult sheep produces hair, and it is qualified therefore just can to wash than the processing of light degree.Can control technology of the present invention, reach best clean effect to guarantee different raw wools.When handling implement comprises microwave radiation, can according to raw wool in the proportional mode of lipid impurity content change the radiation degree.By in present device, comprising into monitor, can obtain the continuous feedback information of relevant lipid Impurity removal degree.Be not difficult to find out, in equipment of the present invention, can adopt the control of microprocessor and computer, so that the washability that requires is monitored, and correspondingly regulate.
Equipment of the present invention can independent or several uses that are cascaded, and like this, along with raw wool moves forward by platform, have just realized progressively cleaning.Scoured wool can be accepted for example carrying out washing treatment subsequently, and to remove residual dirt and other particulate matters, after this, hair will be accepted further processing by general mode.
Material after the liposuction can be handled again, so that separate fat wherein, so this material can be reused again.Can further process by common mode from the fat that raw wool is removed, make lanolin.
Heat raw wool with microwave energy and utilize such fact, promptly the different compound of dielectric constant is also different to the absorption of microwave energy.High dielectric constant materials preferential absorption microwave, therefore the material than low-k is heated earlier.Because the lipid impurity in the raw wool has high-k, their preferential absorption microwaves also are heated, and hair and grease-absorbing material, because dielectric constant is lower, the amount that absorbs microwave is less than fat greatly, so the temperature that heating is reached is inequality.
The microwave frequency that is adopted among the present invention is in the spectrum of 2.45GHz.This frequency is the frequency of using for the Australia area, yet other frequencies also can be used for the present invention.With regard to a scouring of wool device of handling about 4 tons of hair fat every day, adopt present device per hour to need the energy of about 100kW.Adopt an advantage of microwave technology to be, with the microwave generator that can supply at present, energy needed all belongs to adjustable range until about 520kW.
A third aspect of the present invention comprises uses the hair of cleaning according to the method for first aspect present invention.
Understand for the present invention being had more clearly, various Implementation Modes will be described in conjunction with the accompanying drawings.

The invention process pattern
As represented among Fig. 1, the scouring of wool equipment 10 of this embodiment comprises rotary drum 20 and source of microwave energy 30 and dust removal machine 40.One end of rotary drum 20 is provided with import 21 and 22, and raw wool and grease-absorbing material can be through two imports addings thus.
Rotary drum 20 also is provided with import 23, and the microwave radiation of sending from source of microwave energy 30 is passed this mouth and injected.
Dispose, raw wool and grease-absorbing material leave rotary drum 20 from exporting 24, along the opening 41 of passage 25 until dust removal machine 40, and treated hair and grease-absorbed separating substances in dust removal machine.Scoured wool is from opening 42 dischargings, and grease-absorbed material is discharged from opening 43.
During running, the raw wool of not washing (" greasy wool ") is through opening 21 feeding rotary drums 20.The grease-absorbing material of diatomite form is through opening 22 feeding rotary drums 20.With regard to typical case, raw wool and diatomite are to be transported in separately the import 21 and 22 by strength to go.
Microwave radiation is injected rotary drum 20 through opening 23.Raw wool and diatomite are realized mixing under rotary drum 20 rotary actions, are subjected to the irradiation of microwave radiation around here.This microwave energy is absorbed by the lipid impurity in the raw wool, thereby with the fat heating and make its at least a portion liquefaction.Carry out in rotary drum 20 between mixing period, when the two came in contact, diatomite just absorbed liquid fat.Other impurity comprise the dirt and the lanoline that associate mutually with fat, also may be absorbed in the grease-absorbing material, and together are eliminated by this scouring of wool method.By the time raw wool has mixed certain hour with diatomite, and after raw wool was transferred to diatomite, mixture was fed in the dust removal machine 40 through import 41 from the opening 24 of rotary drum 20 fat of requested number.Subsequently, scoured wool separates with grease-absorbed diatomite with the synergy of air movement by machinery, and discharges from opening 42,
Grease-absorbed diatomite is discharged through the opening 43 of dust removal machine 40.Need, grease-absorbed diatomite can randomly be sent to refabrication plant, there, diatomite is separated with hair fat.This can realize by the synergy of microwave energy irradiation with chemical washing." purification " then diatomite can be used further to clean to handle.
According to clean the hair quantity and raw wool in impurity content what, can regulate dosage of radiation.And the consumption of grease-absorbing material also can be regulated according to the fat amount that exists in the raw wool and the washability of requirement.Can carry out field monitoring to this clean process, corresponding change raw wool quantity, dosage of radiation and grease-absorbing material consumption are so that the process of cleaning reaches optimization.
Though embodiment described above adopts an equipment that scoured wool and grease-absorbed material are separated, as can be seen, whole process can be finished in an equipment.And any instrument that can realize scoured wool and grease-absorbed separating substances all is suitable for.These class methods comprise cyclonic separation, washing, clear up, vibrate, filter and rotation with willey.
As what find out from Fig. 2 and 3, the scouring of wool equipment of this embodiment comprises cyclone separator 1, and it comprises the cyclone separating chamber that is surrounded by cylindrical housing, and this chamber is seated in above one section inverted truncated cone.This separation chamber has import 2,3, can add material thus.
This separation chamber also has import 4, and thus, microwave radiation is injected inside, separation chamber.With regard to typical case, import 4 is the waveguides that are connected on the outstanding wind separator 1.Microwave entrance 4 is suitable for around cyclone separator shell 1 by the equal angles spacing arrangement, and is positioned at along the position of vertical certain intervals, as what be clear that from Fig. 3.Suitable way is to be provided with between cyclone separating chamber and import 4 and can to enter import 4 to prevent material from cyclone separating chamber through the screen window of microwave.
Top and bottom at cyclone separator 1 are respectively equipped with outlet 5,6.
During running, the raw wool of not washing (" greasy wool ") is through opening 2 feeding cyclone separators 1.Meanwhile, grease-absorbing material (for example diatomite) is fed into cyclone separating chamber through import 3.With regard to typical case, raw wool and diatomite are to be transported to separately import by strength.
Microwave radiation is injected cyclone separating chamber 1 via import 4.
Raw wool is realized mixing by formed turbulent flow in the cyclone separating chamber 1 with diatomite, accepts the irradiation of microwave energy around here.This microwave energy is absorbed by the lipid impurity in the raw wool, thereby makes fat heating and liquefaction.Carry out between mixing period in that cyclonic separation is indoor, the former just absorbs the latter when diatomite and liquid fat come in contact.Other impurity comprise dirt and lanoline, owing to associate mutually with this fat, also can be absorbed in the grease-absorbing material and go.
Because absorbed liquefaction hair fat, diatomaceous density or weight increase, turbulent air flow again can't support it, so diatomite is just moved to the bottom of cyclone separating chamber.Subsequently, this contains fat diatomite just by metering device (for example, Rotary feeder or valve) and/or air-transport system, shifts out through the opening 6 of cyclone separator 1.
In contrast, raw wool causes density or weight to reduce because fat wherein is eliminated, and therefore, the hair of cleaning is moved to the top of cyclone separator 1, at this, discharges from exporting 5 by metering device and/or air-transport system.
From the grease-absorbed diatomite that take out at the awl end, be suitable for to be transported to a reprocessing chamber, at this, two kinds of compositions, promptly diatomite and hair fat are separated from one another under the synergy of for example microwave irradiation and chemical washing." purification " then diatomite can be used further to clean to handle.
What, can regulate dosage of radiation according to impurity content in the amount of the hair that will clean and the raw wool.And the consumption of grease-absorbing material also can be regulated according to the fat amount that exists in the raw wool and the washability of requirement.Can carry out field monitoring to this clean process, the former gross weight of corresponding change, dosage of radiation and grease-absorbing material consumption are so that the process of cleaning reaches optimization.
In order to check effect according to the inventive method, as above test in the described equipment that comprises rotary drum and dust removal machine when mentioning Fig. 1.2 kilograms of greasy wools (comprising about 25% (weight) hair fat) are by handling as the various conversion scheme of the contained the inventive method of table 1.Diatomite mixes in ratio (weight ratio) contained in the table with raw wool as grease-absorbing material.Useful in order to test whether extra washing/extraction step to improving this scouring of wool method, in some test, comprised water or 1,1,2-trichloroethanes solvent clean.Any other particulate matter that exists during grease-absorbing material, vegetable matter and the scouring of wool is contained in the definition of residual ash.The temperature that provides is the temperature that lipid impurity is reached in the rotary drum during with carry out microwave radiation heating.
Table 1 states clearly the result that the hair of cleaning according to some conversion scheme of the inventive method is tested.From this result as can be seen, adopt this method can from raw wool, dispose fat and other impurity basically.
The invention provides a kind of quick and economic scouring of wool method.And raw wool is to clean according to a kind of mode that belongs to " doing " method basically, and it stays few refuse, is environmentally acceptable therefore.
