Description

Fiber web that the absorption grease is used and the method that removes the food grease
FIELD OF THE INVENTION
The present invention relates to before preparation food, during and the fiber web used of the absorption grease that uses afterwards and the method that from food, removes grease with this fiber web.
The background of invention
Food, especially meat gruel contain big water gaging or other liquid, aqueous and greases.Cook the people of this food because multiple reason all wants to remove grease, comprise the reason of improving taste and improving nutrition.The conventional method that removes grease from food comprises with spoon scoops out grease, freezing and remove solid grease, drains food with strainer, or blots food with paper handkerchief.But these methods can not be easily and/or are removed grease effectively.
The another kind of equipment that removes grease from food is the low fat electric barbecue, for example present grill of selling on American market, commodity GE by name or GEF or EMANGRILL .These electric barbecues have the cooking surface of the band slit of inclination, and it can make the grease fusing at cooking period, separates from food, passes slit, then falls on the inclined surface.But these electric barbecues are relatively more expensive.In addition, these grill volumes are big, account for very large space in the kitchen.Grill can not be used for soup and the stewed food that boils etc.
The mat that the absorption grease is used from food is known in the industry.For example, there are some mats to make by containing polyacrylic spunbond homofil skin and also containing the polyacrylic filler that melts and sprays homofil.Other mats are made by the homofil that contains polyacrylic water thorn.The object lesson of absorption pad has description in authorizing people's such as Terada U.S. Pat 5693420 (people such as Terada) on December 2nd, 1997.This patent relates to the heat fusing composite fibre and the hot melt made by this fiber coagulates supatex fabric.The U.S. Pat 5744406 that the example of mat of grease of being used for assimilating food is authorized Novak on April 28th, 1998 has description.This patent relates to a kind of fabric that applies hydrophobicity and lipophile material that adopts, and removes the method for food grease and fat.The European patent EP 535451A1 that authorized people such as Isakson in April 7 in 1993 relates to a kind of fat absorption pad and packaging bag that is used for cooking in microwave oven.
But existing absorption is lined with three limitation.The first, some existing absorption pad absorbs water and other liquid, aqueous and greases from food.Efficient is not high and bad like this because the absorptive capacity of part be used to absorb liquid, aqueous after, the absorptive capacity that enables to absorb a large amount of greases reduces.For example, for for example being not limited to the purposes that removes grease and so on from soup, the absorptive capacity of these mats can reduce.The second, this existing absorption pad generally only can be used for for example being not limited to soup and stewing the food that boils at the food that lower temperature (for example not being higher than about 120 ℃) is cooked down.At high temperature, these absorption pads can melt or be crimped to deformed configurations, therefore no longer can absorb grease effectively.But cooking food for example is not limited to hamburger in frying pan, sausage, pimento, or the temperature of bacon, usually reach about 175 ℃ and more than, can keep the temperature of globality far above some existing absorption pads.The 3rd, some existing mat in use can lose hair or feathers; Both made the outward appearance of food bad, also may together be eaten with food.
The general introduction of invention
The invention provides and be used to prepare the absorbent web that contains grease and liquid, aqueous food, this net is oil loving, and preferably hydrophobic is at high temperature flexible; And depilation is few.The absorbent web of this entangled fiber contains at least about 55% bicomponent fiber, and this bicomponent fiber has lipophile crust and core, and core has enough heat endurances, makes net can keep the temperature of globality to be higher than situation only rindy.
Brief description of drawings
Though this paper has comprised claim, it specifically indicates and has clearly illustrated right of the presently claimed invention, can think, also can understand the present invention better in conjunction with the accompanying drawings from following description, and same numbering is represented same part in the accompanying drawing, wherein:
Fig. 1 is the amplification profile of a kind of form of bicomponent fiber of the present invention;
Fig. 2 is the perspective view of a kind of embodiment of absorbent web;
Fig. 3 is the perspective view of a kind of embodiment of absorbent web, and this net has many layer heat seals together, and has the hole along the heat seal at center.
Detailed description of the invention
The invention provides and absorb the fiber web that grease is used, it comprises bicomponent fiber, this bicomponent fiber is an oleophyllie hydrophobic, and the high temperature that has enough thermal stabilities to stand to prepare generally to run in the food process (generally is about 120 ℃ in frying pan, until about 200 ℃), and cost is cheap, depilation is few." grease " this term is often referred to fat and/or oil, for example is not limited to, and is rich in energy, and extensively is present in animal tissue, the nut of plant, seed and fruit, or the organic compound in several mineral matters and the synthetic." oleophylic " term is meant that grease is had compatibility.The net of oleophylic used herein is meant such net, and its surface was at 5 seconds or may absorb oil droplet less than 5 seconds, for example was not limited to the oil droplet of vegetable oil." hydrophobic " used herein is meant such material, and it preferably absorbs oil on liquid, aqueous.It is liquid, aqueous that but term " hydrophobic " also can refer to absorb some.Can absorb preferably that some are liquid, aqueous, because when in the liquid, aqueous non-water base food of staying in the cooking-vessel, the meat gruel in the frying pan for example, the user of absorption mesh can aware grease and do not absorbed effectively.
The term that relates to fiber and web frame used herein, and its definition and The NonwovenHandbook (1998, INDA) the middle unanimity of describing, its content is with reference to being incorporated into this.Term used herein " bi-component " refers to exist any two kinds of fibre structure parts of separation.Two kinds of separated structures parts are made by different Chemical composition thats usually.Though other forms of bicomponent fiber also is fine, what the present invention relates to is " core-skin " type bicomponent fiber, wherein crust basically (promptly at least 90%) cover core, or with concentric manner or with eccentric manner.
Usually, the thermal stability that the material shortage that lipophile and hydrophobicity are bigger is enough at high temperature keeps the globality of netting, but the higher material of heat resistance generally lacks described hydrophobicity again.Amazingly be, core-skin type bi-component form can provide the fiber of not only oleophylic but also hydrophobic (crust), also can at high temperature keep the globality (core) of structure.The lipophile crust has compatibility to grease, and this just can make grease cover single fiber, and fiber web is retained in grease in the hole between the fiber.The hydrophobicity of crust can guarantee that its ability that absorbs a large amount of greases can not reduce, because liquid, aqueous that absorb is the very most of of fiber web absorptive capacity.Core material should have enough thermal stabilities up at least about 175 ℃ with more preferably keep the globality of net at least about 200 ℃ temperature.Term " single-skin drum " refers to such fiber, and the size and dimension of its bicomponent fiber is identical, but 100% the constituting of fiber by skin material.Term " net globality " is meant that net can keep being applicable to high temperature food, and keeps the absorbent properties of net as herein described.
Skin material can form fiber, and preferably oleophylic and hydrophobicity.This material can comprise and be not limited to polyolefin for example polypropylene (PP), polyethylene (PE), gather 4-methylpentene (PMP) or their blend.Preferably, skin material is polypropylene (PP).In addition, skin material can be the blend of polypropylene (PP) and poly-4-methylpentene (PMP).
Core material can form fiber and enough heat endurances are arranged, and makes net up at least about 120 ℃, more preferably 175 ℃ and preferably can keep globality at least under about 200 ℃ again.This material can comprise and be not limited to polyester, nylon, polyethylene terephthalate (PET), artificial fibre, regenerated cellulose or their composition and/or blend.Preferably, core material is polyethylene terephthalate (PET).
In one embodiment, crust is made up of polypropylene (PP), and core is made up of polyethylene terephthalate (PET), and the weight ratio of crust and core is about 1: 1.Fibroreticulate Unit Weight is 25-400 gram/square metre (gsm), more preferably from about 60-250gsm.
In another embodiment, crust is at least about 25%-75%, more preferably at least about 40%-50% polypropylene (PP); Core is at least about 25%-75%, more preferably at least about 40%-50% polyethylene terephthalate (PET).
In another embodiment of the present invention, crust accounts for about 10%-30% of fibre weight, more preferably from about 15%-20%.Crust is at least about 25%-75%, more preferably at least about 40%-50% polypropylene (PP).With at least about 25%-75%, more preferably at least about the blend of the poly-4-methylpentene (PMP) of 40%-50%.Core accounts for about 70%-90% of fibre weight, more preferably from about 80-85%.
Preferably, the size of fiber is about the 0.05-10 dawn, 1-8 dawn more preferably from about, preferably about again 3-5 dawn.The section shape that is used for constructing fibroreticulate bicomponent fiber can be the circular shape arbitrarily that maybe can increase surface area, thereby improves the oleophylic performance of net.It includes but are not limited to: circle, trilobal, dumb-bell shape, rectangle, positive square, hexagon, star or their combination.Except the basic configuration of section, also can see the additional shape of second kind of section.Can play the increased fiber surface area.
Preferably, the fiber web right and wrong are woven, though net also can be woven.The nonwoven bicomponent fiber can assemble desired web frame by in many technology common in the industry any one, and these technology comprise and are not limited to combing, spunbond, air lay, wet-laying, compound or laminate form.Preferably, web frame is formed by the combing method set.
Then, bicomponent fiber can form net by the technology of any kind common in the industry, comprises and is not limited to: tangle, play felt, or other non--melt bonded technology or their combinations.If that in fact adopts is not only into network method, so bicomponent fiber is preferably tangled, make that it is main tangling.Such entanglement can water thorn (spunlaced) or acupuncture (felt) realize.Can adopt melt bonded or heat bonding, if but like this, should limit melt bonded degree, make the absorbability of net as herein described to keep.Usually, in melt bonded net, the fused materials of fiber can together flow into the hole gap and form bond site, reduces effective free area that can absorb and keep grease on the quantity in hole gap between the fiber and size and the fiber surface thus.Carry out in the heat bonding process at stack, fabric is compressed in the bond site or near, can reduce the size of hole spacing again.And the increase fabric weight just can further reduce the hole spacing.
Usually, if will be stood the above temperature of minimum molten component melt temperature by the fiber web that heat (or fusion) bonding bicomponent fiber forms, fiber web will disintegrate, because bonding having scattered.High temperature is the most harmful to the fiber web that sheath/core bicomponent fiber forms, and high melting point component did not rise or seldom worked bonding this moment.Amazingly be, sheath/core bicomponent fiber is formed and the fiber web that tangles according to the present invention can stand to be higher than the temperature of the fusing point of low-melting crust, because: 1) fibroreticulate globality is mainly provided by the entanglement of fiber; 2) core of high melting temperature helps to keep the globality of netting.
Tangle, for example entanglement of water acupuncture manipulation or needle point method makes the fiber structure that is combined into one, and it has the globality of structure, still can keep the enough clearance spaces and the free area of fiber.Fiber preferably tangles along the direction perpendicular to network plane, makes hole spacing maximum.Preferably, described absorption method of testing records with the back, is at least about 0.15g in the oil absorption of 120 ℃ of every square centimeter of nets.Entanglement can make fiber web in 175 ℃ the uptake dry weight greater than net, more preferably is 2 times of its weight at least, preferably is 5 times of its weight more at least.The Unit Weight of preferred net becomes with final application requirements and entanglement method, but is about 20-600 gram/square metre (gsm) usually.Usually, the matrix that weight is lighter, about 20 grams/square metre-Yue 200 grams/square metre, be that jet net-spraying method forms by the water thorn.Usually, acupuncture is used for forming the heavier fabric of Unit Weight, for example is not limited to, about 80 the gram/square metre-Yue 600 the gram/square metre fabric.Acupuncture also can be used for many layers together solid, make its mix Unit Weight be about 80 grams/square metre-Yue 600 grams/square metre.The composition of each layer can be same to each other or different to each other, and decides with final use.
Fiber web can be a monolayer material, also can be made of the multilayer that overlaps each other.If fiber web is a multilayer, these can be glued together by any kind of known in heat seal, acupuncture or industry method.Preferably, multi-layered web gets up by heat-seal bond.The heat seal of multi-layered web can be the pattern with any kind, and these patterns can be continuous or discontinuous.The heat seal method must be able to apply enough heats and pressure so that partial melting high temperature fiber component guarantees stable on heating bonding at least.In addition, bond area should be to realize that multilayer is bonding and/or seal necessary minimum of a value, so that keep maximum hole spacing.Some weak lines also can be arranged on the fiber web, comprise and be not limited to the hole line, laser scored layer line, or the initial incision mode of being convenient to tear, this helps using the fiber web of a part.Preferably, the position of these weak lines is along fibroreticulate heat seal, separates along weak line so that help.
Fiber web of the present invention can be multiple size and dimension.For example, fibroreticulate size can be to be designed to absorb-grease of specified quantitative.Preferably, the planar dimension of net sheet makes surface area of its one side be about about 600 square centimeters of 200-, 300-500 square centimeter more preferably from about, preferred again 340-380 square centimeter.In addition, fibroreticulate shape can be similar to the shape of food, and the shape or its size and dimension that for example are not limited to bay leaf or garlic bulblet can be similar to cooking-vessel.
During use, fiber web of the present invention is during preparation food and remove grease afterwards.Food, especially meat gruel contains a large amount of liquid, aqueous and greases.Absorbent web of the present invention is put into food during cooking food contiguous, for example is not limited in the frying pan or the top of soup and pimento.At cooking period, absorbent web preferably absorbs grease.After food is cooked, take out absorbent web and throw away.Absorbent web of the present invention also can be used for for example being not limited to pizza, hunting pork or hamburger sops up excess grease from food.
As mentioned above, absorption grease fiber web provided by the invention, its absorbability height, the globality that runs into high temperature and can keep when saturated netting, and when contacting foodstuff seldom or do not have depilation, adhesion, balling-up or a loose phenomenon.Because the heat-blocking action of net, fiber web also can make the food insulation longer.Therefore the invention provides before the cooking or the preparation food, during or remove improving one's methods of grease afterwards.Usually, this method comprises and places net to such an extent that be the state that is communicated with of oil with food.The preparation of food comprises and is not limited to the hand adjustment system of using, and mixes the cooking, heating or otherwise processing or improvement or processed food." oil be communicated with ", be meant before the preparation food, during or afterwards, goods are put into can be from the position of food absorption grease.But the oil connection can accomplish to be not limited to following manner in the following manner: 1) net is put into food and mixed or put into food mutually; 2) will net direct the contact with foodstuff surface or the contact of one part surface; 3) during preparation food, net is placed into and the grease position contacting, but not necessarily directly contacts with food.
At first, fiber web of the present invention can mix with food.For example, can stir around food or in the food or the rotation fiber web, maybe food can be stirred around net.This method can guarantee that net contacting foodstuff surface area reaches the absorption of maximum.This method is particularly useful for absorbing grease when cooking food for example is not limited to meat gruel.
The second, fiber web is contacting foodstuff in use.Because the fibroreticulate globality of the present invention, fiber web seldom or do not have depilation, adhesion, balling-up or a loose phenomenon.For example, a kind of method is that food is contacted with fiber web.Food can be solid (for example being not limited to pizza) or liquid (for example being not limited to soup and fricassee)." contact " can comprise and be not limited to pad and press, inhale (blotting), Orly or encase action such as food on food.Another kind method is that food is wrapped in the fiber web, and pushes food gently so that contact more web surface.Another kind method is that fiber web is sent food as the heat pad.Because fiber web of the present invention preferably is made up of thicker material, fiber web can fill up as heat when foodstuff surface absorbs grease.For example, fiber web can be used in that mobile food for example is not limited to meat or cooking food from drip pan, as platter.Fibroreticulate another kind of using method comprises when removing surperficial grease, makes the food insulation long period with net covering food, and this is because net has heat-blocking action.Fibroreticulate another using method comprises and encases food, for example is not limited to leftovers, removes grease with fiber web between the storage life.Another kind of using method is that food is put into above the fiber web, allow grease suck in the net, can make simultaneously liquid for example be not limited to water or other liquid, aqueous clearance spaces through net, with have with holes or other can make the device for transferring on the surface of the device that liquid discharges, it is similar for example to be not limited to strainer.In addition, fiber web can be put into discharger for example be not limited to strainer above, then food is put into net above, therefore can make liquid for example be not limited to water or other are liquid, aqueous through fiber web and discharger.In addition, through the liquid of net,, can collect in this manner, be used for food and for example be not limited to preparation delicious low fat gravy and sauce being with or without under the situation of discharger.
The 3rd, fiber web can use by this way, makes the grease of it and food be the state that oil connects, but contacting foodstuff not.For example, cooker can banking make grease collect on this limit.Then, fiber web can be put into this limit of pot, absorbs.When cooker tilted, using a cooker was not the position that pot is collected that limit of grease with the food retaining, is favourable but optional yet.Another example comprises that use fiber web of the present invention splashes on stove, micro-wave oven or other the peripheral region with the thing of avoiding spilling as " splash guard " in cooker.Although other absorbent articles can melt when contacting with the cooker of high temperature in the prior art, fiber web of the present invention can be put on the food that is just preparing at cooking period, even contacts cooking-vessel when the cooking.When using by this way, fiber web can all or part of covering cooking-vessel, prevents that grease from splashing the container outside.This has just exempted the trouble of cleaning peripheral region.Another example is included in cooking back with fiber web wiping of the present invention or cleaning cooker, sops up the residual grease of having in one's care in cooking-vessel.That remain heat when cooker thereby grease is when still uncured, and this is especially effective.
As mentioned above, fiber web also can be used for micro-wave oven.A kind of method is in micro-wave oven these fiber web goods to be used as covering or spatter shield (as mentioned above).Another kind method is included in cooking period and in micro-wave oven food is wrapped in the fiber web.This can make steam overflow safely, and stops the grease that spills simultaneously.Then food will become fragile in micro-wave oven (crisp), helps to prevent that food is roasting not saturating because remove grease with fiber web from food.
In addition, the present invention includes a kind of system, it comprises fiber web and information, and this information is by writing or sound and/or figure sheet mode tell the consumer to use fiber web to absorb the method for grease.Therefore use with described information-related packing material very importantly,, for example be not limited to described improved fat absorption by writing or sound and/or picture tell the consumer to use fiber web that some benefits are arranged.Described information for example can comprise, the advertisement of doing on all common medium from one's body explanation and image, removes ability in order to the grease of telling the described uniqueness of consumer at packing or fiber web.Information can only be passed through vival voice, and only by ways of writing, only by image mode, or the mode of their any combination is propagated.Information can provide with the form of description of writing, this explanation can be provided on the fibroreticulate packing or packing in or fiber web from one's body or be used on the independent goods packaging together (for example being not limited to the scraps of paper) with fiber web.Obviously, in this aspect of the invention, described information needn't directly be included in construction system with goods.For example, if fiber web has been sold, this has just constituted system of the present invention with regard to for this fiber web has carried out advertizing.
Usually, fiber structure is made of their true qualities velveteen.In addition, the fiber structure that absorbability is high has big voidage usually.Because many fibers are not to be bonded together densely, so big voidage is generally just arranged.Therefore, the fiber structure that absorbability is big has bigger fiber loss or depilation phenomenon.Especially when fiber structure was used for food, it was bad to lose hair or feathers.And the hair of taking off contacts with food always, makes the outward appearance of food bad, also may together be ingested with food.
Preferably, fiber web should lose hair or feathers to lack big absorbent properties again.According to following test, the fibroreticulate accumulation velveteen of the present invention test value is at least about 8 times of its weight preferably less than 30 in the amount of 120 ℃ of absorption greases.Preferably, the size of net is, makes that 8 times of its weight are about the 40-100g grease 120 ℃ the time, more preferably at least about the 55-75g grease.
The velveteen test value of accumulation is the total amount of fiber web depilation in the test of carrying out respectively for three times.Test for the first time is to use the 1-inch section that fiber web is cut edge, and number goes out from the fiber free-ended number of this section selvage protrusion more than 250 microns.The selvage that measure to protrude fiber should be in the variable density of net to the single fiber discernible position that begins to become.Can use the stone ring that precious decorations worker uses or the instrument of other suitable low multiplication factors.Test for the second time folds fiber web, marks the section of 1-inch along fold line.Number of times goes out the fiber free-ended number of folded edge protrusion more than 250 microns from net again.Test for the third time is to use 1 inch long adhesive tape.This adhesive tape is SCOTCHMAGICTAPE , by the 3M company production of Minnesota State St.Paul.Its step is earlier adhesive tape to be weighed, and described adhesive tape firmly is pressed on the web surface, then it is peeled from network, and weighs and adhered to the band of fiber.Write down weigh for twice poor.The velveteen test value of accumulation is that the fiber counting of preceding twice test adds the algebraical sum of test result for the third time, and its unit is a milligram/square inch.The velveteen test value of accumulation is more preferably less than 25, more preferably less than 22 preferably less than 30.
Preceding twice test relates generally to observable depilation problem.If it is outstanding from net surface to cross multi-fibre, the user can be observed net and can come off fiber in food so.Result of the test is to use can the come off about measurement of radical of fiber under the analog force effect that is applied to net of when net for the third time.Actual dose,epilation is more preferably less than 7 milligrams of/square inch nets, more preferably less than 5 milligrams of/square inch nets preferably less than about 10 milligrams of/square inch nets.
Fibroreticulate absorption value is calculated by following absorption test.At first, with about 48 ounces of CRISCO  vegetable oil, UPC37000-00482, the Procter﹠amp of Cincinnati; GambleCompany produces, and puts into a flat glass bowl of PRYEX , and this bowl is of a size of 190 inches * 100 inches, article number 3140, and by the CORNING of New York Coming, INC  produces.A rotating rod is put into the bowl that fills vegetable oil.Then, bowl is put on the stirrer/hot plate.The model of stirrer/hot plate is ModelPC620, and power is 1113 watts, and by the CORNING of New York Coming, INC  produces.Bowl is heated to make oil be 120 ℃.Adopting 120 ℃ of temperature is because this is the general temperature of cooking food in frying pan.Weigh one 6 inches * 6 inches square fiber web, accuracy is ± 0.01g.Then, this fiber web was put into oil 30 seconds.Afterwards, fiber web is taken out from bowl, and be flat on the metal screen, the grid distance of this filter screen is the 1/2-3/4 inch.Make fiber web horizontal positioned on filter screen was drained oil 15 seconds.Then, the fiber web of band oil is weighed again.Calculate fibroreticulate dry weight and be with the poor of oily fibroreticulate weight, it is exactly the uptake of grease.This absorption value is calculated as the amount that the Unit Weight fiber web absorbs grease.Absorption value in the time of 120 ℃ preferably is at least about 8 times of fibroreticulate dry weights.
Usually, the fiber web that absorbability is bigger more may lose hair or feathers.Thus, lose hair or feathers with regard to requiring fibrous matrix to have high-absorbable less.The velveteen test value of accumulation and the ratio of 120 ℃ of absorption values also can be calculated.The velveteen test value of accumulation and the ratio of 120 ℃ of absorption values are more preferably less than 2.5, most preferably less than 2 preferably less than 3.
Usually, known fiber structure in the industry for example is not limited to and both absorbs the paper handkerchief that grease absorbs water fluid.But the fragrance of most foods and taste all are contained in the water fluid.Thus, just require such fiber web, its grease above the preferential absorption water fluid makes it can remove grease and stays taste.This point for example is not limited to when frying in shallow oil, baking and frying in the cooking, is even more important.
Many waterborne liquid base foods for example are not limited to soup, and fricassee or pimento etc. all are to cook under about 65 ℃ of temperature.Desired is that fiber web absorbs seldom liquid, aqueous when being used for removing grease from water base food.Thus, be elected to be the temperature of measuring liquid, aqueous capacity with 65 ℃.The hygroscopicity value of fiber web under these temperature measured by above-mentioned absorption test, different water rather than the oil of being to use, and water temperature is 65 ℃.
In addition, desired be can be on 65 ℃ of preferential liquid, aqueous from water base food the fiber web of absorption grease, equally also from food, absorb grease under the high temperature that can in frying pan, be run into, and do not have tangible thermal deformation.Under the temperature more than 200 ℃, grease begins to give birth to cigarette.Therefore, be elected to be the temperature of measuring oil absorption with 200 ℃.The oil factor of fiber web under these temperature measured with above-mentioned absorption test, and different is that the oil temperature is at 200 ℃.
About 200 ℃ oil factor (with respect to the weight of oil of net weight) preferably is at least about 2 with the ratio of about 65 ℃ hygroscopicity value (with respect to the water weight of net weight), more preferably is at least about 3, preferably is at least about 4 again, most preferably is at least about 4.5.
