Definitions

  • the present invention relates to an apparatus for finishing textile materials and the like, and more particularly to a machine for applying finishing compositions dispersed in chlorinated organic solvents by the spraying technique.
  • fabrics as well as other textile products and the like are treated with finishing compositions in order to confer to them particular characteristics. It is known, for example, that in order to confer antistain characteristics to the fabrics and other textile articles, these are treated with compositions based on polymers containing perfluorinated chains.
  • foulard technique which consists of the following operations:
  • the immersion time is defined by the passing rate of the material throughout the bath and by the length of said bath.
  • hand of the fabric means the sensation of agreeableness which one feels when touching a fabric and which is the resultant of a plurality of characteristics depending on the fiberto-fiber friction, the fiber-to-skin friction, the elasticity modulus of the fiber and yarn, the structure of the fabric, its superficial electrizability, etc. It is known that the judgment of the textile expert on the hand of a fabric, yarn or knitted material determines its price and its success in the market.
  • One of the objects of the present invention therefore is to supply the textile technician with an apparatus making it possible to apply finishing compositions onto textile materials without resorting to the know foulard method.
  • a further object of this invention is to supply the textile technician with an apparatus making it possible to apply finishing compositions fabrics and the like without deteriorating the hand characteristics of the treated articles.
  • An additional object of this invention is to supply the textile technicians with an apparatus making it possible to advantageously apply finishing compositions dispersed in chlorinated organic solvents of the aliphatic series.
  • FIG. 1 schematically illustrates an elevated side-view of an embodiment of the apparatus according to this invention.
  • the essential feature of the apparatus according to this invention is that it enables to apply finishing compositions onto textile materials by the spraying method.
  • Said spraying method is well known and is widely employed in many types of treatment. Said method, however, has never been employed to apply certain finishing compositions onto textile materials, on an industrial scale.
  • the fact that the spraying method is not used in this particular industrial field is to be ascribed principally to the lack of adequate apparatus.
  • finishing compositions suitable for being applied by the spraying method were not found in the market.
  • compositions are particularly suitable for being applied onto textile materials by the spraying technique.
  • Such compositions must be applied onto the articles in a series of operations, the sequential order of which to be strictly observed in order to obtain the desired results.
  • the apparatus according to this invention is particularly appropriate for applying said new finishing compositions consisting essentially of dispersions of polymeric substances in chlorinated organic solvents of the aliphatic series.
  • FIGURE in the drawing is a schematic, side elevation view of the preferred embodiment of the invention.
  • the apparatus according to this invention substantially consists of:
  • a spraying chamber 10 through which the fabric is passed, driven by rolls, vertically with respect to a plurality of spraying units 20 which spray the finishing composition perpendicularly onto the fabric.
  • the spraying units 20 are preferably fixed and are arranged in one or more rows directed towards both surfaces of the fabric to be treated.
  • Said spraying units are preferably of a mechanical atomizing type and are preferably fed by a pump 7.
  • Said pump must have an appropriate power in order to confer the nozzles of the spraying units 20a pressure of at least 3 kg/cm
  • the number and type of the spraying units 20 must be so chosen as to allow a complete and sufficiently uniform spraying onto the whole fabric.
  • the temperature in this chamber is comprised between 85 and 120 C.
  • the fabric is dried in an air flow, which is circulated (as shown by the arrows) through the chamber by a fan 11.
  • the air Prior to being admitted into the chamber, the air is preferably heated, for example by means of a steam system 22 with finned tubes. In such case, the steam flow is controlled automatically by the temperature adjusting device in the chamber.
  • the concentration of the organic solvent vapors in the chamber is kept constant by the fan 13 which conveys a fraction of air and solvent vapors through a cooling system 14 provided with finned tubes.
  • said cold air is mixed with the main flow of air and solvent vapors downstream the first fan and upstream the heating system.
  • temperature is kept constant by circulating (as shown schematically in the drawing) an air flow which is caused to circulate by a fan 12. While circulating, the air is heated for example by passing through a system 23 of stem-heated finned tubes. Temperature is kept constant by an adjusting device acting upon the flow of the heating steam.
  • the apparatus according to this invention may be equipped with other complementary elements.
  • One of these complementary elements consists of the deodorizing roll 4 arranged downstream the chamber 18.
  • the fabric is conveyed over the apertured roll 4 connected to the fan 2, which originates inside the roll 4 a suction stream, which removes the solvent vapors from the fabric and conveys them (in the'direction indicated by the arrow) into a solvent recuperator provided with activated carbon filters.
  • a similar deodorizing roll may be arranged downstream the chamber 19.
  • Additional complementary elements of the apparatus according to the invention consist of a tank to contain the solvent of the finishing compositions, and one or more tanks 21 to contain the finishing compositions used for treating the fabrics.
  • the finishing composition tanks are preferably provided with adequate stirrers.
  • a pump is used to transfer the solvent from its tank into the tanks containing the finishing compositions.
  • the finishing compositions Prior to being sent to the spraying units 20, the finishing compositions are preferably filtered, for example through the filters 8.
  • a pump 9 is used to recycle into the tanks 21 the compositions recovered at the bottom of the spraying chamber 10.
  • exhauster 16 for the polymerization smokes which is situated at the top of the chamber 19, as well as the device 17, the purpose of which is to cool the treated fabric.
  • the fabric 3 to be treated is unrolled under the action of controlled rolls from the roll 1, and is progressively passed, within controlled periods of time, through the spraying chamber 10, the chamber 6, the chamber 18, around the deodorizing roll 4, through the chamber 19 and the cooling device 17, and is finally collected on the roll 5 of the treated fabric.
  • the apparatus according to the present invention may be adapted for the treatment of any textile material other than fabrics. Further additions and/or modifications may be contributed by those skilled in the art to the embodiment herein described and illustrated merely by way of nonlimiting example of this invention, while remaining within the scope of the appended claims.
