The specific embodiment
The present invention relates to Wiping article, its at least one surface is provided with abrasive areas, and this abrasive areas provides friction effect for these articles for use, and surperficial remainder then can be these articles for use normal wiping action is provided.The present invention includes imbibition width of cloth material and the abrasive areas that places on its liquid-absorbent surface, this abrasive areas comprises the particulate binder material of curing at least, and described abrasive areas is opened by the imbibition region separation of width of cloth material.Here employed " particulate curable binder material " meaning is at room temperature to be processed into particle form for solid-state material, and it can heat energy or other forms of energy (if heat cured or crosslinkable) are next to be softened and curing by heating and follow-up cooling (if thermoplastic words) or by fully being exposed to.
The present invention relates to provide the method for making this Wiping article, it is littler that this method and the method for present employing are compared ambient influnence.The use of particulate binder material can make abrasive areas be created on the surface of width of cloth material and can not produce volatile organic compound (VOCs) in the method according to the invention, and can also make that the energy consumption demand of this method is lower than the method that adopts liquid bonding material.
In yet another aspect, the present invention relates to provide such Wiping article, except effective friction effect, also have noticeable outward appearance.The use of particulate binder material make binding material in the effect deposit of electrostatic force to the surface of width of cloth material: promptly, therefore can on width of cloth material, produce the abrasive areas of sharp outline, and therefore provide attractive product to select to client with various pattern forms.
Wiping article shown in Fig. 1 and 2 comprises imbibition width of cloth material 3 and adheres to the abrasive areas 5 upper surface 4 (as shown in the figure), that arrange according to the pattern form of rule of this width of cloth material.This abrasive areas 5 comprises abrasive grains and abrasive grains is sticked together mutually and adheres to the particulate binder material of the lip-deep curing of width of cloth material 3.Between abrasive areas 5, exposed the liquid-absorbent surface 4 of width of cloth material 3.Abrasive areas 5 shown in Figure 1 is bar shaped: but, this is dispensable, also can use other shapes as described below.Abrasive areas 5 also needn't be arranged with the pattern form of rule.
A kind of method of making Wiping article 5 is shown schematically among Fig. 3.The width of cloth material 3 of continuous length by from cylinder 7 feedings by powder coating case 9.This width of cloth material 3 is transferred by powder coating case 9 on the plane that the conduction conveyer 11 by ground connection provides, and, in case 9 inside, the upper surface 4 of width of cloth material is contact masterplate or mask 13 closely, and the patterns of abrasive areas 5 has cut into the form of this masterplate or mask by known way.As shown in Figure 3, masterplate is the continuous strip that moves through powder coating case 9 with the speed identical with width of cloth material 3.Dried granules material (comprising abrasive grains 14 and curable binding material 15 at least) is fed to the electrostatic gun 17 that is positioned at coating case 9 tops from hopper 16.
In method shown in Figure 3, electrostatic gun 17 is known in the powder coating technical field, and they are used in the electrostatic powder application system so that the powdery paints of static electrification is coated on the workpiece of ground connection in this field.A kind of typical known electrostatic powder application system is by the powder hopper, high-voltage power supply (for example producing voltage) up to 100kV, and electrostatic gun and powder recovery system are formed.Powder by fluidization, is fed to spray gun then in hopper, its powder guiding workpiece to be applied.The electrode of spray gun front is connected to power supply and electrostatic charge is passed to the powder coating material at the powder coating material during by the workpiece of directive ground connection.Electric charge make powder particle be drawn towards and the workpiece attached to ground connection on.The powder that is not deposited on the workpiece is recoverable to and reuses.
In method shown in Figure 3, handle electrostatic gun 17 so that under electrostatic attraction, gravity and synergy, dried granules material 14,15 guiding is downwards arrived masterplates 13 and (passing the cut-off parts of masterplate) arrives on the upper surface 4 of width of cloth material 3 from the flow of atomization air of spray gun 17.Masterplate 13 is removed from width of cloth material 3 then, and the zone 5 at the interval of granular materials 14,15 formations is stayed on the width of cloth material surface according to the patterns that masterplate limited.The granular materials 14,15 that remains on the masterplate 13 is collected in any suitable manner, just as any granular materials of the bottom of falling case 9, and can reuse.
Then width of cloth material 3 is exposed to and makes under the softening conditions of solidifying then of particulate binder material 15, so that the abrasive grains 14 in each interval region 5 is bonded to each other and be bonded on the surface 4 of width of cloth material 3.In process shown in Figure 3, suppose that particulate binder material 15 is thermosetting or thermoplastic, and width of cloth material 3 is therefore through heating furnace 19, width of cloth material is heated with softening particulate binder material in this stove, so: the heat cure binding material also can solidify in heating furnace 19, and thermoplastic binder material will be solidified by cooling off after width of cloth material 3 leaves heating furnace.Then, be transformed into as shown in Figure 1 big or small suitable single Wiping article 1 (after if necessary, being stored on the cylinder 21) at the width of cloth material 3 that has abrasive areas 5 at interval on its surface 4.
Utilize the described method of Fig. 3, have been found that at width of cloth material to enter passing through the process of heating furnace 19 from case 9, the zone that is deposited on the interval of granular materials 14,15 formations on the width of cloth material 3 in the powder coating case keeps interference-free.Believe that this is a granular materials 14,15 in the effect deposit of the electrostatic force result to the width of cloth material 3.Therefore, look very clean along with the abrasive areas 5 that is formed on the interval on the width of cloth material by heating furnace and, present pleasant outward appearance to the user by sharp outline.
Keep enough wiping actions and keep pliability and be easy to being handled by the user in order to ensure Wiping article 1, preferably, abrasive areas 5 should not cover the surface above about 50% Wiping material 3.If abrasive areas covers more large-area Wiping material surface, the imbibition ability of Wiping article and attriting performance can significantly reduce so, because that can increase the possibility that Wiping article slides on institute's clean Surface.Usually, have been found that the effect that when abrasive areas 5 covers about 15-40% on Wiping material 3 surfaces, can obtain the best.The mode that the size of single abrasive areas 5 can be arranged on the Wiping material surface according to them and different, if but they are too big, and then Wiping article can slide on want clean Surface and effectiveness reduces.In addition, preferably, abrasive areas 5 does not need correctly to determine before use the direction of Wiping article 1 in the lip-deep arrangement of Wiping material 3 directionality that do not have to guarantee the user.
Preferably, an abrasive areas 5 is only arranged in particular cases on the Wiping article surface, this abrasive areas should not cover yet and surpass this articles for use surface of 50%, and like this, the user can select to utilize the friction zone or the imbibition zone of Wiping article.
Powder coating case 9 can be any suitable known type that is used in the powder coating application.Preferably, masterplate 13 is answered non-conductive but can is any suitable material that is provided also, thereby the granular materials 5 that makes its surface 4 that can closely contact width of cloth material 3 guarantee to be deposited on the width of cloth material is sharp outlines.Masterplate 13 can be, for example the band that constitutes of webbing (for example, the silk screen band) or polymeric material (for example, PVC, polyester, polyurethane or polyamide).
The form of masterplate 13 and nonessential formation continuous strip as shown in Figure 3.Alternatively, method shown in Figure 3 can be used as semi-continuous process and implements, and wherein single masterplate member was placed on the discrete section of product before width of cloth material enters powder coating case 9.Then, when that part of width of cloth material moves through coating during case 9, granular materials 14,15 deposits on the masterplate from spray gun 17.When that part of width of cloth material shifted out coating case 9, masterplate was removed, and is cleaned then and reuses.Meanwhile, width of cloth material moves in the heating furnace 19 so that softening as described above and cure adhesive material.Equally, neither provide conductive surface smooth, ground connection on this surface, to carry width of cloth material by conveyer 11 by coating case 9.For example, in semi-continuous process, when discrete section of product enters coating case 9, can provide above-mentioned surface by the conductive plate that inserts between conveyer and the discrete section of product.
The quantity that is deposited on the granular materials 14,15 on the width of cloth material can move through the speed that applies case 9 by change width of cloth material and adjust.Also can be used for the quantity of the spray gun 17 in the case or be provided with and adjust by change by changing spray gun.By the quantity of the granular materials 14,15 that is deposited is reduced to reduced levels, and omit masterplate 13 simultaneously, can make such Wiping article, one of them surface will be covered by the grinding part of the granular size of random distribution, and these grinding parts are opened by the imbibition region separation of width of cloth material.In this case, the area of grinding part should not surpass about 50% of wipe surfaces area equally.
Do not need sharp outline as the abrasive areas on the fruit bat material 35, so just can be by the abrasive areas of general pattern pattern being provided in the surface that provided below width of cloth material of conduction conveyer 11 and omitting masterplate 13.For example, conveyer 11 can be a grid, and the granular materials from spray gun 17 concentrates on preferential gridline along conveyer on the surface of width of cloth material 3 in this case.But, gridline is not a sharp outline, and some granular materials also can be deposited on the width of cloth material between the grid line.
As another possibility, do not need sharp outline as the abrasive areas on the fruit bat material 35, so same suitable is, can use the width of cloth material 3 (for example crape material) with following surface texture to form the abrasive areas of general pattern pattern by omitting masterplate 13, this surface texture can make some zone of width of cloth material more closely contact conveyer 11 than other zone.More particles material 14,15 will be deposited on contacting with conveyer 11 the most closely on those zones of width of cloth material.
The coating case 9 that can use other applying device to replace having spray gun 17 is realized 14,15 electrostatic precipitations of dried granules material on width of cloth material 13.These comprise, for example such device, thus wherein granular materials and air are blended in the fluidization chamber and by ionized air and are with static can stick on the width of cloth material.Then, as mentioned above, the width of cloth material that has adhered to granular materials above is transported to heating furnace 19.
If desired, the dry granular material 14,15 that is fed to electrostatic gun from hopper 16 can comprise the additive that the powder coating technical field is commonly used, and such as pigment, filtering material helps stream material (flow aids) etc.The some of them additive, for example pigment and filtering material may be mixed in in the binding material.
