Definitions

  • This invention relates to a process for wet treatment of a textile web with an organic solvent and also to subsequent drying of the textile web with a hot air stream.
  • the object of this invention is to provide an improved process, and also for the carrying out of the process a suitable apparatus, wherein the textile web can shrink unhindered in the wet treatment zone and wherein a relatively simple transport means through the drying zone is used.
  • a process for wet treatment of a textile web with an organic solvent and subsequent drying of the textile web with a hot air stream is characterized in that the textile web is first completely shrunk in hot solvent, and is then laid evenly on a web transport means through which air can pass, said transport means conveying the textile web through a further processing zone.
  • the fully shrink textile web is laid evenly on the web transport means. Consequently, the textile web can now run between a pair of rollers to remove the solvent swiftly. Moreover by laying the web evenly on the web transport means undesirable blemishes occuring during the drying process are avoided.
  • the web transport means preferably comprises a mesh belt or a suction drum.
  • the shrinking process conveniently takes place in a trough of hot solvent.
  • FIGS. 1 to 3 show longitudinal sections of three respective embodiments of an apparatus for carrying out the process according to the invention.
  • the embodiment shown in FIG. 1 comprises a shrinking zone 1, a washing zone 2, a zone 3 for web, a drying zone 4 and an airing zone 5.
  • the shrinking zone 1 consists of a bath 6, for example of U-shape, filled with hot organic solvent, through which the textile web 7 freely moves and within which it completely shrinks.
  • a mesh belt 8 then carries the web through zones 2 to 5.
  • the textile web 7, having shrunk completely in the shrinking zone 1, is laid evenly, that is without folds, on the mesh belt 8.
  • organic solvent is sprayed by spray means 9 on to the textile web 7.
  • the washing fluid dripping from the web is collected in a container 10 which is situated between upper and lower runs of the mesh belt.
  • the textile web 7, carried by the mesh belt 8, then runs between a pair of coacting rollers 11 which mechanically squeeze out a large part of the solvent still remaining in the web.
  • the textileweb 7 is dried by means of a recirculating hot air stream.
  • part of the air is continuously sucked out of the zone 4 and passed through a condensation device in which the solvent is removed.
  • the textile web 7 is subjected to a clean air stream which removes any solvent still remaining in the web.
  • the air sucked from the zone 5 is preferably passed through an adsorption device to remove the solvent held therein.
  • FIG. 1 may be modified by omitting the washing zone 2, the washing process instead taking place in the bath 6.
  • the fully shrunk web then runs from the washing and shrinking zone (bath 6) first between the pair of coacting rollers 11 mechanically removing the solvent, and is then dried by hot air in the drying zoned.
  • FIG. 2 comprises a different shrinking zone 1" and zone 3' for mechanical removal of solvent from the washed textile web, while the zones 2, 4 and 5 are similarto those of the embodiment of FIG. 1.
  • the textile web 7 is carried through the shrinking zone 1' by two endless-circulating; tenter chains which may be provided for example with needle carriers which engage longitudinal edges of the web.
  • the textile web in known manner, in small folds is engaged by the needles of the tenter chains so that the web can fully shrink in the zone 1' as desired.
  • the hot solvent is, in this embodiment, sprayed onto the textile web 7 in the shrinking zone 1' through spray means 13.
  • a container 14 collects the liquid dripping from the web.
  • the zone 1' is preferably heated so that the hot solvent is not appreciably cooled before it contacts the web 7.
  • the mechanical removal of the surface liquid carried by the textile web'7 after leaving the washing zone 2 is effected in the embodiment of FIG. 2 by a pressure air stream which is supplied in zone 3' by a group of nozzles I5 and through which the web is passed. It will be understood that alternatively a suction air stream may be used.
  • a pressure air stream which is supplied in zone 3' by a group of nozzles I5 and through which the web is passed.
  • a suction air stream may be used.
  • the removal of the organic solvent from the textile web by such an air stream is favored by the relatively high specific gravity of the solvent.
  • the same solvent can, of course, be used for the shrinking and washing procedures.
  • different additives can still be used in the two zones.
  • the embodiment shown in FIG. 3 comprises two chambers 22 and 23 in a common housing 21, of which chamber 22 is a washing and shrinking zone and chamber 23 is a solvent removing and drying zone.
  • the chamber 22 includes a trough 24 which is filled with a hot organic solvent.
  • a perforated drum 25 is provided in the chamber 23 which is divided into three sectors 26, 27, 28, each sector having a peripheral zone in contact with the textile web 33. Rollers 29, 30, 31, 32 serve to guide the textile web 33. In the region of the perforated drum 25, two tenter chains 34 (indicated as a dotted line) engaging respective edges of the textile web 33 may be provided.
  • the textile web 33 first passes through the trough 24 for a sufficient time that it can shrink freely and completely. It then passes in to the perforated drum 25 and the solvent is first mechanically removed by a suction air stream (indicated at 35) in the sector 26. In the following sector 27 the textile web is then dried by a hot air stream (indicated at 36). Said hot air stream is supplied by heating means adjacent sector 27 of the drum (not shown). In the third sector 28 the textile web is aired (indicated at 37) and thereby any remaining solvent is removed.
  • a process for wet treatment of a textile web with an organic solvent comprising the steps of:
  • washing liquid used in the step of washing is the same organic solvent used for the step of shrinking.
  • washing liquid is an organic solvent
  • the step of washing includes spraying the organic solvent onto the textile web.
  • step of removing the washing liquid includes passing the textile web between adjacent coacting rollers for squeezing the textile web therebetween for removing the liquid therefrom.
  • step of shrinking the textile Web includes filling a trough with hot solvent; and passing the textile web loosely through the trough of hot solvent.
  • step of shrinking the textile web includes placing the textile web loosely on a conveying means; and spraying hot solvent onto the textile web being carried on the conveying means.
  • step of removing the washing liquid includes forcing a stream of air through the textile web to remove the liquid therefrom.
  • step of airing includes forcing a stream of air through the textile web.
