Description

Cleaning cloth

The present invention relates to a kind of cleaning cloths, and it includes fabric-supported materials and the coating/dipping layer being provided thereon.The cleaning Good sanitary characteristics are combined together by cloth with sliding property in a novel way, and manufacturing cost is low and wash stability is good.

In housework and specialized cleaning, it is known that various for cleaning the cleaning cloth of floor or other surfaces.This Kind cleaning cloth is made of the fabric substrate of such as single layer, thus has simple structure.Importantly, very for cleaning cloth It receives dirty from surface to be cleaned well and discharges completely as far as possible during wringing out dirty.In addition, the water suction of cleaning cloth Property and dehydration property are also critically important.On the one hand, water for attachment it is dirty disintegrate be it is required, on the other hand, water is again with disintegrating It is dirty, or loosening particulate matter of dust etc. is combined together, and is detached from surface to be cleaned by cleaning cloth.For using For person, the sliding capability of cleaning cloth is critically important.Be embodied in, when clean big surface (such as window, blackboard, big desk, metope, Vehicle body) when, cleaning cloth be easier slide, thus realize better human engineering and wiping when it is more laborsaving.On the contrary, clear It is clean lesser or pollute more serious surface when, user prefers the biggish cleaning cloth of frictional force, so as to attachment it is dirty more It is detached from well, good feel feedback can be obtained in cleaning process in other words.

It is well known that cleaning efficiency can be improved in the fabric-supported material of coating or dipping layer.Therefore, textile material Such as polyurethane (PU-) coating or dipping layer can be equipped with.In the everyday practice of this field, polyamide-based coating or dipping layer Dosage can be by the way that matrix impregnation be obtained in the solution of polyurethane and dimethylformamide (DMF).

Another known method is, the coating or dipping layer of fabric-supported material by the microfoam containing polyvinyl fluoride poly- second Enol fiber composition.In addition, to have good adhesion between fiber and coated/impregnated material, because in coated/impregnated In the process, fiber surface forms durable, washing surely in dissolving aqueous medium, and between backing material and coating material The surface of fixed chemical-physical combines.

Main task of the invention is, provides the cleaning cloth as started said type, and the cleaning cloth is by good cleaning Characteristic is combined together with good water imbibition and sliding property, while having wash stability.Should have using the cleaning cloth There is very excellent cleaning action.

Further say, the cleaning cloth should also can rinse when, especially dirty particle dirty by what is received, letter Singly successfully discharge.It can be to avoid following scenario described, when cleaning chrome-plated surface/polished surface, by institute by the cleaning cloth Received sand (for example, containing quartz components) and the surface is caused to wear or be damaged.In addition, the cleaning cloth should be able to be right Article or surface carry out mild cleaning.Finally, coating or dipping layer reply show enough adhesive force in fabric-supported material, To ensure in cleaning, when especially machine-washing, there is corresponding mechanical stability.According to the present invention it is possible to be understood that machine washing When high stability, as in Bundesgesundheitsblatt-Gesundheitsforschung- Gesundheitsschutz10,2007, page1345 (federal health handbook-health research-health protection 10,2007, the Page 1345) defined in Eltra washing methods, use 7 grams of Eltra as detergent/disinfectant, sterilisation temp 60 DEG C, the processing time is 20 minutes, liquor ratio 5:1 and when the AB of the zone of action, and the weight loss of cleaning cloth is lower than 5wt%.

According to the present invention, this task can be realized by following cleaning cloth: the fabric-supported material that the cleaning cloth includes Material is at least partly equipped with a certain amount of polyvinyl fluoride microfoam, the weight percent for accounting for cleaning cloth gross weight of polyvinyl fluoride microfoam Less than 60wt%, preferably smaller than 50wt%, and without vinal or vinal in fabric-supported material Content accounting is less than 50wt%.

Cleaning cloth of the present invention is characterized in that: it does not have the fabric-supported material formed containing vinal Material, fabric-supported material are equipped with polyvinyl fluoride microfoam.Wherein, polyvinyl fluoride microfoam can be with the shape of coating and/or dipping layer Formula exists, and its pore size having is less than 100 microns.It is preferred that microfoam had not only been presented coating form but also dipping layer is presented Form, that is to say, that the space between fiber is filled with polyvinyl fluoride microfoam, and is equipped with made of polyvinyl fluoride microfoam Coating.

Surprisingly, cleaning cloth of the present invention has outstanding wash stability.Up to the present this is for leading to Be for normal starting point it is astonishing, at present generally, it is considered that being coated with poly-vinyl alcohol solution to vinal Or dipping is necessary high stability.Pass through chemical similarity possessed by both materials and vinal Be partly dissolved good chemically and physically combined so that having between fiber and microfoam.Due to this reason, of the present invention Cleaning cloth cleaning when, especially machine washing when, have good mechanical stability.

However, Practical experiments according to the present invention show that as long as foam is microfoam form, the support of non-polyvinyl alcohol Material, such as polypropylene/polyethers alum/polyamide (PP/PES/PA), can also be realized with polyvinyl fluoride it is good, first wash Wash stable combination.So in cleaning cloth of the present invention, the content of polyvinyl alcohol, especially vinal Content is less than 50wt%, or again smaller than 30wt%, or is less than 10wt%, especially less than 5wt%.In addition, cleaning cloth is not Containing polyvinyl alcohol, do not have vinal especially.

The present invention is not intended to be bound in a specific mechanism, and inventor, which thinks to be formed inside microcellular structure, to be drawn Sail is stretched to play a major role for the good combination of non-polyvinyl alcohol substrate and polyvinyl fluoride coating.

According to the present invention, fabric-supported material is at least partly equipped with a certain amount of polyvinyl fluoride microfoam, and polyvinyl fluoride is micro- The weight percent that foam accounts for cleaning cloth total weight is less than 50wt%, preferably smaller than 30wt%.Adjust such polyvinyl fluoride microvesicle Lesser specific gravity shared by foam is advantageous, because while polyvinyl fluoride microfoam does not lose its softness in the dry state Property and thus lead to the cleaning cloth of wiriness, but can continue to the fabric and its soft feel that retain final cleaning cloth.

Practical experiments show when backing material is formed as open-celled structure, are conducive to polyvinyl fluoride microfoam and are attached to knit Object backing material, such as non-woven fabrics.It the advantage is that, the poly-vinyl alcohol solution for being used to prepare polyvinyl fluoride microfoam and using can To penetrate into backing material well, and non-woven fibre can be for example wrapped up comprehensively or without spinning filament.

When using density bigger backing material, then it can come by using with more less viscous poly-vinyl alcohol solution Realize that polyvinyl fluoride microfoam passes through the excellent permeability of backing material.As known to professional person, polyvinyl alcohol contracting first Aldehyde microfoam is transformed by polyvinyl alcohol and formaldehyde.This process reduces the water solubility of polyvinyl alcohol., according to the invention it is preferred to Polyethylene microfoam is lower than 5wt% in 100 DEG C of water solubility.

Practical experiments show that cleaning cloth of the present invention is other than wash stability with higher, it is also by it Water imbibition and sliding capability are combined together with sanitary characteristics.At the same time, the dirty of receiving can preferably be washed from cleaning cloth It is de-.

It is contemplated that fabric-supported material is at least partly made of super-fine fiber material.This embodiment can be suitble to In certain purposes, this is because when using fiber made of hydrophobic material, since the superfine fibre yarn of knitting is had Capillarity, available good water absorbing capacity (for example, with the percentage relative to cloth net weight to measure).

Embodiment according to the present invention, cleaning cloth is by hydrophobic material and hydrophilic material (polyvinyl fluoride microvesicle Foam) combine, therefore generally have amphipathic.This cleaning cloth is for lipophilic dirty and hydrophilic dirty have There is very high cleaning action, its range applicatory is very extensive.

It is advantageous in that using another of polyvinyl fluoride, since it has free OH group, it has especially strong absorption Power.Facilitate to further increase the hydrophily of polyvinyl fluoride material in the form of microfoam.Since microcellular structure is had Fine porosity, this material shows higher hydrophily.In addition, polyvinyl fluoride microfoam can wrap further or completely The fiber and yarn in some cases for wrapping up in fabric-supported material, to be formed between backing material and coating/dipping layer Stable mechanical bond.When using hydrophobic material as backing material, this is particularly advantageous, because polyvinyl fluoride microfoam is real It will not be perfectly adhered in such material on border.

Preferred embodiment according to the present invention, backing material and polyvinyl fluoride microfoam made of non-woven fabrics are incorporated in one It rises.Wherein, the advantage is that production is simple and low in cost, nevertheless, the cleaning cloth still have outstanding cleaning effect and Wash stability.

Using knitwear or the backing material of braid form wash stability can be further promoted in the following manner: Since the space of yarn interconnects, backing material wash stability with higher itself is knitted or woven.

Practical experiments are it has been shown that polyvinyl fluoride coating and/or the weight per unit area for impregnating layer are preferably that 10g/m2 is arrived 150g/m2, preferably 50g/m2 to 100g/m2.Wherein, the weight per unit area of fabric-supported material is preferably that 80g/m2 is arrived 200g/m2, preferably 90g/m2 to 180g/m2, especially 100g/m2 to 140g/m2.

Fiber made of hydrophobic material of the present invention is added into fabric-supported material as basic material.This hair The concept of " hydrophobicity " will understand according to traditional sense in bright.Especially in the present invention, if it is tight being formed by material Gathering the surface of main body has more than or equal to 90 ° of contact angle, then the material is defined as hydrophobic material.Many institute's weeks Know, contact angle can be measured using the edges surveying instrument of such as Kr ü ss company.Same situation is also applied for hydrophilic material system At fiber.

It has been found that fiber is particularly suitable for containing following material or is made of following material: polyamide or polyester, viscose glue Fiber, hydrophobic stickies fiber, hydrophilic viscose rayon, modified poly ester, polyacrylonitrile, triacetate, acetate are such as poly- Ethylene and polyacrylic polyolefin, the mixture of polyvinyl chloride and/or above-mentioned substance.According to the present invention, particularly preferably using poly- Amide, especially polyamide -6 or polyamide -66；Polyethylene and/or polyester, especially polyethylene terephthalate, and/or The mixture of the above substance.

Confirm herein, fiber made of the mixture by polyester, viscose rayon, polyethylene, especially these substances for The present invention is especially suitable.

It is preferred that with staple fibre and/or continuous microfilament.Preferred embodiment according to the present invention, this fabric-supported material It should include polyester, especially polyethylene terephthalate and/or modified poly ester.This polyester both can be used as unique raw material It uses, can also be mixed with other fibers (such as viscose rayon).

The linear density range of fiber is 0.05 to 3dtex.When fiber linear density is in superfine fibre range namely 0.1 When to 1dtex, this is advantageous certain applications.It is using the advantages of superfine fibre, it has good cleaning Effect, touch feeling that is very soft and therefore can showing pleasure.For example, the linear density range of superfine fibre can arrive for 0.05 1.0dtex, especially from 0.1 to 0.7dtex.

It can be seen that from fabric-supported material with the coating containing polyvinyl fluoride/dipping layer pro rate and pass through selection Fabric-supported material and the available corresponding cleaning cloth of the corresponding proportion of polyvinyl fluoride microfoam, although polyvinyl fluoride microfoam It can lose substantially in the dry state flexible and therefore cleaning cloth can be made further stiff, but the fabric-supported material is still Part remains its fabric property and pleasant softness.

Preferably, total weight per unit area of cleaning cloth is 90g/m2 to 350g/m2, more preferably 200g/m2 to 300g/

m2.Wherein, the fibrous amount of institute is preferably 60g/m2 to 200g/m2, more preferably 100g/m2 to 120g/ in cleaning cloth m2.Fiber suitable for manufacturing fabric sheet can manufacture into different form and color in cheap mode, and using conventional Technique applies the coating or dipping layer of polyvinyl alcohol with method in a simple manner.

According to the present invention, the preferably full surface of sheet material is equipped with coating or dipping layer.The advantages of this embodiment is, full table The coating or dipping layer in face make sheet material be strengthened, to improve its stability.In addition to this, due to hydrophilic poly- fluorine second Alkene content is higher, on the one hand can remove well big quantity of fluid from surface to be cleaned.On the other hand, this to wait for when wiping One layer of thin, uniform fluid film can be only remained in clean surface.This allows to realize the cleaning without lines in iridescent surfaces.

For in principle, the fabric substrate of reinforcing and the fabric substrate of nonreinforcement can be used as fabric sheet use.For Mechanically stable cleaning cloth is obtained, fabric-supported material is at least partly beneficial by mechanical, calorifics or chemical strengthening.Especially It is for non-woven fabrics, random or section aligned arrangement fiber can and/or calorifics mechanical by sewing and/or change It learns and reinforces.
