Definitions
- the invention relates to a method and a device for solidifying a fabric web comprising a nonwoven.
- web comprising a web
- this also means webs that consist entirely of nonwoven.
- a nonwoven is a textile fabric that consists of filaments that are thermally, chemically or mechanically bonded together.
- Mechanical hardening involves the known method of hydroentanglement, in which water jets are supplied under pressure to at least one surface of the web and cause compacting of the web.
- the fleece After the water jet application step, it is necessary to dry the nonwoven fabric.
- the fleece After the water jet application step, it is necessary to dry the nonwoven fabric.
- the fleece then a suction device, by means of which water is sucked off, and finally a dryer in which the evaporation of befindaji in the web residual liquid is supplied to feed.
- the processing step of drying in the dryer is energy intensive.
- the invention is therefore based on the object, a Ver ⁇ drive and a device for solidifying a web comprising a web to create, the energy consumption is lowered.
- the method according to the invention provides for squeezing out liquid from the already consolidated nonwoven web before the step of drying.
- the liquid squeezing step according to the invention can be used instead of the previously used siphoning.
- superfluous liquid is also sucked off prior to squeezing, as this increases the effectiveness of the squeezing operation and allows a web of lesser residual moisture to be fed to the drying process.
- a particularly gentle drying process is effected by suction before squeezing. This is explained by lower cross flows of the liquid during the Abquetschschrit- tes, since due to the lower residual moisture only smaller remplisstechniks ⁇ keitsmengen per unit time must emerge from the web.
- the liquid used is preferably water. Although it is conceivable to use other liquids which are more readily volatile, for example at room temperature, to solidify the nonwoven, preference is furthermore given to using water, since this is the most economical and no problems with the provision and / or disposal prepares.
- the apparatus for using the method according to the invention comprises a device by means of which pressurized liquid can be fed to the fabric web, a squeezing device connected downstream of the device by means of which liquid can be squeezed off the web, and a dryer for drying the material web.
- the web is fed in this apparatus continuously from the solidification device via the squeezing the dryer, wherein after passing through the squeezing the web has such a low residual moisture that the required for effecting the drying process by the dryer e- nergiemenge is reduced.
- the device additionally comprises a suction for sucking excess liquid, which - seen in the feed direction of the web - is connected upstream of the squeezing.
- the apparatus designated as a whole by 100 comprises a securing device 1.
- the latter has a drum 2 about which a web B comprising the web to be consolidated is guided through approximately 220 °.
- nozzles 3 are arranged, by means of which water jets 4 are supplied under pressure in the direction of the normal of the web B.
- the web B After circulating the drum 2, the web B is guided by an endlessly around deflecting rollers 5, 6, 7 with the advance speed of the web recirculating belt 8.
- a suction device 9 vorge ⁇ In the area in which the web B rests against the screen belt 8, on the web B opposite side of the screen belt 8 see a suction device 9 vorge ⁇ . It comprises a suction bar 10 which can be pressurized with negative pressure and which comprises a suction opening 11 extending over the entire width of the web.
- the web B is fed via further guide rollers 12, 13 a squeezing 14. It comprises a pair of squeezing rollers 15, 16 which form a nip 17 between them.
- the contact pressure of the nip rollers 15, 16 on the guided through the nip 17 Wa ⁇ renbahn B is dimensioned such that a further part of the still remaining in the Wa ⁇ renbahn liquid is squeezed, but the web is not mechanically acted on a degree, that could affect the quality of the web.
- the web B is fed to a dryer 20 for removal of the residual moisture and subsequently to further treatment or winding.
