Definitions

  • the present invention is concerned with wet transfer printing of materials, especially wool and wool rich fabrics.
  • Conventional wet transfer printing processes comprise printing the design on paper with suitable dyestuffs, impregnating the fabric to be printed with an aqueous solution which may for example contain a dye fixation catalyst and a thickener, and bringing the paper and the fabric into close contact by applying pressure and heat to transfer the dye from the paper to the fabric and to fix it in the sane operation.
  • aqueous solution which may for example contain a dye fixation catalyst and a thickener
  • chlorine or a chlorine donor is added to the impregnation solution which is used as part of the conventional wet transfer printing process to wet the fabric immediately prior to its being brought into contact with the transfer paper,
  • the impregnation solution which is used as part of the conventional wet transfer printing process to wet the fabric immediately prior to its being brought into contact with the transfer paper
  • the chlorine donor is introduced into the untreated woollen fabric separately from the impregnating liquor but immediately prior to the impregnation step, impregnation being effected by passing the fabric through a liquor coating device immediately prior to being brought into contact with the transfer paper.
  • the liquor applied by the coating device contains, in accordance with known practice, an acid which is effective to release the free chlorine into the wool.
  • the drawing corresponds to Fig. 3 of UK Patent Specification No 1492036 to which attention is hereby directed for a detailed discussion of wet transfer printings
  • the apparatus illustrated in the drawing comprises a cylinder 10 which is journalled for free rotation about its central longitudinal axis.
  • the cylinder 10 is arranged to be heated to an operating temperature of about 110°C-125°C, for example by steam at a pressure of approximately 10-30 p.s.i. supplied to the interior of the cylinder 10.
  • the transfer process involves passing a first web 14 of backing paper (if required) around the cylinder 10 in contact with a second web 16 of wet fabric to which the transfer is to be applied, a third web 18, consisting of the transfer paper bearing the transfer to be printed, being passed around the cylinder in intimate contact with the second web 16.
  • a fourth web comprising an endless blanket 20 of water impervious, fabric-reinforced rubber, passes around the outside of the three webs 14, 16, 18 to urge these webs against the cylinder 10.
  • the inner web 14 of backing paper is stored on a roll 22. After passing around the majority of the periphery of the cylinder 10, the inner web 14 is taken up on a roll 36.
  • an infra-red pre-heater 68 is-provided for pre-heating the webs 16 and 18 before entry onto the cylinder 10.
  • the transfer paper web 18 is guided onto the cylinder 10 from a storage roll 48 and subsequently taken up by a roll 57.
  • a plurality of radially displaceable, driven pressure applicators in the form of rollers 66 and located behind the blanket 20 at different points around the periphery of. the cylinder 10.
  • the pressure rollers 66 are rotatable about their longitudinal axes by a mechanical drive (not.shown) such as a crown wheel and pinions or by a chain.
  • the pressure rollers 66 are adapted to be individually actuable, whereby the actual pressure applied by each roller to the web sandwich between that roller 66 and the cylinder 10 is pre-selectable.
  • a pre-selected pressure distribution can be set up whereby, for example, the webs are subjected to a series of gradually increasing pressure transients as the webs progress around the cylinder.
  • the present-invention may be applied to this known apparatus as follows.
  • chlorine or a chlorine donor such as sodium hypochlorite
  • a chlorine donor such as sodium hypochlorite
  • the apparatus is modified as explained in our copending Application No 35049/77 whereby the impregnation solution is not introduced in the mangle 80 but is applied to the web in the form of a thick paste by a coating device disposed in the region of the infra-red heater 68 in the drawing, that is, immediately upstream of the cylinder 10.
  • the chlorine is introduced into the fabric by passing the fabric through a chlorine containing chemical, such as sodium hypochlorite, to achieve a measured pick-up of such chemical prior to the fabric reaching the coating device.
  • the hypochlorite solution could thus be added at the position of the mangle in the drawing.
  • the coating liquor contains an acid and can be of the type normally used in the wet-transfer printing of wool in accordance with our aforementioned Application No 33049/77.
  • the coating liquor contains an acid and can be of the type normally used in the wet-transfer printing of wool in accordance with our aforementioned Application No 33049/77.
  • the coating liquor contains an acid and can be of the type normally used in the wet-transfer printing of wool in accordance with our aforementioned Application No 33049/77.
  • the coating liquor contains an acid and can be of the type normally used in the wet-transfer printing of wool in accordance with our aforementioned Application No 33049/77.
  • a scoured, but unchlorinated wool serge fabric is impregnated in a solution containing the following ingredients, mixed with a high speed stirrer in the order given.
  • Natrasol 250 HH is hydroxyethyl cellulose which is a water soluble textile thickening agent.
  • Nonidet SH 30 is a solution of a non-ionic wetting agent.
  • the resulting solution has a pH of approximately 3.5.
  • the fabric After impregnation in this solution, the fabric is then mangled so that the fabric retains 100-110% of the solution, based on the dry weight of the fabric.
  • the transfer paper used was printed by a gravure technique such as the Aquatran W paper produced by Transprints (UK) Limited using inks containing suitable dyes such as:
  • the paper/fabric composite was run with the back of the wet fabric against the heated cylinder.
  • the printed fabric was separated from the spent paper and washed for 5 minutes at 45°C in 1 gm/litre ammonia solution, rinsed in water and dried.
  • a scoured, but unchlorinated wool serge fabric is impregnated in an aqueous solution of sodium hypochlorite containing 3.5 gm/litre available chlorine and adjusted to pH 4.5. with acetic acid.
  • the impregnated fabric is then mangled so that the fabric retains 70% of the solution based on the dry weight. of the fabric.
  • the thus impregnated fabric is passed through a liquor coating device such as the one described in Example 1 of patent application No. 33049/77.
  • the coating liquor is make up according to the following recipe and yielding a pH of approximately 2.
  • Example 1 The thus treated fabric is then wet transfer printed according to Example 1, except that the. paper/fabric composite was run with the back of the transfer paper against the heated cylinder. After transferring, the printed fabric was separated from the spent paper and washed as in Example 1.
