Definitions

  • the invention relates to a device for wetting a web with a liquid, wherein the web is passed in a running direction through the device, comprising guide means for guiding the web and application means for applying the liquid to the web.
  • wet webs such as a film, a nonwoven, a paper or a textile knitted fabric
  • liquid chemicals to provide the web with a functional equipment.
  • This may be, for example, a dyeing, an impregnation, a stain-proof coating, a nano-coating, an antibacterial coating or the like.
  • Such a method and a corresponding device are for example from DE 10 2006 038 339 A1 known.
  • the web to be wetted is guided over a rotating applicator roll, which is partially immersed in a chemical tank and by means of which the chemical is applied from the tub to the web.
  • Two guide rolls which are arranged in front of and behind the applicator roll, serve to guide the fabric web over the applicator roll.
  • a disadvantage of the known from the prior art devices is that it depends on the contact angle between the web on the applicator roll, the web speed, the web grammage, the application roller speed and the viscosity of the wetting substance at the apex of the applicator roll for penetrating the substance through the Web can come.
  • the degree of penetration can be so strong that not inconsiderable amounts of the wetting liquid on the side facing away from the applicator roll of the web emerge from this, be thrown in the web direction of travel into the environment and thus lead to an aerosol mist.
  • This aerosol mist is disadvantageous in many respects. Thus, it settles on the surrounding surfaces of the system, which makes them dirty and can be significantly attacked, depending on the chemical. Such contamination of the system can permanently reduce plant safety. Settling on floors and stairs leads to slippery surfaces that pose a risk of injury to people working on the device. These are also exposed to a potentially harmful contamination of the air through the aerosol mist. Liquid that settles on the surrounding parts of the installation, in particular on trusses running over the material web, can drip down onto the material web and thus adversely affect product quality. Finally, the escaping into the environment aerosol mist means a significant cost overhead, since up to 30% of the substance to be applied to pass through the web and volatilize and can not be used for wetting.
  • suction hoods for extracting the aerosol mist are used above the web in the field of wetting, such as in the DE 10 2008 040 414 A1 described, however, which represent a major plant outlay and only with a certain structural condition Distance to the web can be installed. For this reason, such devices can not prevent liquid volatilizes in the immediate vicinity of the wetted web and / or deposited on machine parts. Also, liquid that settles in the edge regions of the suction hood, drip back onto the web. In addition, the extracted liquid usually can not be used for wetting, so that the loss of such liquid is still significant.
  • the object of the present invention is therefore to provide a device for wetting a web with a liquid, which overcomes the above-mentioned disadvantages of the prior art.
  • the device according to the invention for wetting a material web with a liquid is characterized in that a spray protection which can be placed on the material web to be wiped is provided and the material web can be guided in a running direction between the application means and the splashguard.
  • the invention provides a mechanical protection device under which the material web runs over the application means and by means of which an aerosol mist which spreads out into the environment of the material web can be effectively prevented already at the point of origin.
  • the splash guard rests directly on the web, so that volatilization of the wetting chemical and thus a loss of application liquid can be completely prevented.
  • the fabric splash guard rather a uniform, homogeneous impregnation of the web is effected.
  • Liquid that passes through the web moistens the web of the side facing the splash guard, but this is immediately cleaned from the trailing web.
  • the finished wetted web due to the penetration of the wetting chemical on both sides have the same properties.
  • At least one applicator roll is provided as the application means, which rotates in a tub containing the wetting liquid and over which the fabric web is passed away.
  • the application means By applied in certain areas on the applicator cover strips can also be a strip order can be realized.
  • other application mechanisms for example a spray application, are also possible.
  • guide means preferably guide rollers and at least one dipping roller are provided, by means of which the web can be guided in a straight line and tightly over the application means, in particular over the applicator roll.
  • the fountain roller is usually adjustable in height, so that their position can be chosen so that the web has contact with the applicator roll.
  • the splash guard according to the invention is formed in one embodiment of the invention as a film which has a sufficient resistance to chemicals.
  • the film is particularly preferably made of polytetrafluoroethylene (PTFE, for example, known as Teflon ® from DuPont) is manufactured.
  • PTFE polytetrafluoroethylene
  • Such films are liquid impermeable, so that in the region of the cover of the web through the film no wetting chemical can escape. They can adapt extremely flexibly to the web and are uncomplicated to manufacture and provide.
  • PTFE is also characterized by a very high chemical resistance and is not attacked even by aggressive chemicals. It also has a very low coefficient of friction, so that the PTFE film of the moving web despite tight concerns against excessive resistance and is subject to little wear.
  • PTFE Due to its low surface tension, PTFE is difficult to wet, so that, as already stated above, liquid that has passed through the fabric web is directly cleaned off the trailing material web and does not permanently adhere to the film.
  • PTFE-based materials are contemplated, eg PTFE-coated fabric webs or woven PTFE film webs and the like.
  • the splash guard which is preferably formed as a film, extends in the running direction L of the web over the area in which the wetting takes place, i. when using an applicator roll in general on the vertex of the applicator roll, as well as a preceding this and an adjoining this range of z. B. in each case at most 1 m, preferably in each case at most 0.75 m, as well as at least over the entire width of the web. In this way, it is ensured that no liquid can be thrown off the material web from a defined area around the application medium.
  • the splash guard is held by retaining means on the web.
  • This may be, for example, at least two hollow profiles extending transversely to the direction L of the web and between which the splash guard is clamped at both ends.
  • the holding means are preferably height-adjustable, so that by appropriate positioning of the holding means, the film can be stretched and pressed onto the running web or easily to increase the voltage can be pressed into it.
  • the applicator roll 5 rotates in a filled with a chemical 3 tub 9, in which it partially immersed.
  • the chemical 3 is used to impregnate the web 2 and is transmitted to the web 2 by contact contact in the region of the vertex S of the applicator roll 5.
  • a foil 4 splash guard made of polytetrafluoroethylene (PTFE) on the web 2 on.
  • the thickness of the film 4 is for example 0.1 mm - 1 mm and is in FIG. 1 , in particular in relation to the thickness of the web 2, not shown to scale.
  • the film 4 extends in the running direction L of the web 2 over the region of the apex S of the applicator roll 5, in which the wetting takes place, as well as a preceding this and an adjoining this range of 0.5 m. Transverse to the direction L, the film 4 extends over the entire width of the web. 2
  • the film 4 is clamped at its two ends facing the guide rollers 6 and the fountain roller 7 in also transverse to the direction L extending holding means 8, which are formed as hollow profiles. Through this, the film 4 is held on the web 2.
  • the holding means 8 are height-adjustable according to arrows H1, H3 formed, so that the film 4 is first brought to the web 2 and then pressed onto the web 2 or can be easily pressed into this to improve the voltage.
  • the height adjustment can equally on both holding means 8 act or each holding means 8 is assigned its own, independent height adjustment.
  • the composite of film 4 and web 2 is pressed by the holding means 8 with constant contact pressure on the applicator roll 5. As a result, a uniform wetting of the web 2 with the chemical 3 is made possible, without creating dead spaces between the applicator roll 5, web 2 and film 4, in which liquid could collect. This mode of operation is referred to as hydrophilic production.
  • the holding means 8 and also the usually height-adjustable dip roller 7 can be adjusted so that the web 2 runs in a straight line over the applicator roll 5, but the film 4 serving as a splash guard still maintains surface contact with the web 2.
  • This operating position is also referred to as hydrophobic production.
  • a device which prevents the formation of an aerosol mist in the wetting of a web with a liquid and all the disadvantages associated therewith and thus leads in particular to a significant saving in wetting liquid.
  • a particular advantage of the device according to the invention lies in its flexibility and ease of retrofitting.
  • the splash guard can be easily adapted to different web dimensions and installed in a variety of plant types, even subsequently.
