Definitions

  • This invention relates to textile materials and, more particularly, to the application of finishing agents to textile materials.
  • the treating of textile materials with finishing agents involves a procedure wherein the finishing agent is either dissolved or dispersed in a suitable liquid medium carrier such as an aqueous or organic liquid, and then applied to the textile, such as by passing the textile through a bath or vat containing the solution or dispersion. Thereafter, the carrier is removed from the fabric, usually by evaporation with or without heat. Since only a small amount of the finishing agent is needed to achieve the desired effect, a relatively large amount of carrier (water) is used to assure uniform distribution of the finishing agent. This results in relatively large amounts of liquid medium which must be removed from the fabric. Consequently, a substantial amount of the cost incurred in such processes resides in the liquid medium removal step.
  • a suitable liquid medium carrier such as an aqueous or organic liquid
  • finishing agent For many textiles it is desired to apply more than one finishing agent thereto. For example, it may be desirable to first dye the textile and then apply a durable press agent or to apply both durable press and soil release agents to the textile. Since relatively few of such combinations of finishing agents can be applied together from the same medium, such multiple agents are typically applied to the textile in a serial manner. Thus, for example, a coloring agent is first applied to the textile; the textile is then dried; and the colored textile then treated with a further fabric finishing agent in a conventional manner and then re-dried.
  • US-A-4099913 and FR-A-22 66 766 describe the applying of textile treating compounds using foam compositions that break immediately on contact with the textile material and are rapidly absorbed.
  • a further object of the present invention is to provide a serial process for treating a textile with at least one finishing agent which does not require intermediate fixation of the textile prior to application of a foam composition thereover.
  • a still further object of the present invention is to provide a process of the type mentioned which does not present difficulties in the control of the amounts of finishing agent applied to the textile.
  • a textile is first treated with a finishing agent-containing composition and, without prior fixation, (i.e., complete removal of all liquid therefrom), is thereafter treated with a second covering composition which is applied in the form of a foam.
  • the textile is then treated to collapse the foamed composition and effect uniform penetration of the finishing agent into the fabric.
  • the treatment of textiles in accordance with the present invention has the advantage of eliminating costly liquid removal procedures between application of finishing agents. Moreover, it has been found that application of the second finishing agent in the subsequently applied foamed composition avoids the earlier- referred to dilution effect arising from conventional application of the second finishing agent in a liquid solution or suspension since significantly less liquid per se is required when such compositions are applied as foams, and since the foam can be applied without the need for passing the textile through a bath or vat containing the liquid finishing agent composition.
  • the application of the first finishing agent-containing composition to the textile can be accomplished in accordance with conventional techniques, e.g., by continuously passing the textile through a bath or vat containing the liquid composition.
  • the first finishing agent composition may be applied in the form of a foam. In this method of operation, this first foam applied to the textile is collapsed, prior to application of the second foamed composition to the textile. Such collapsing of the first applied foam may occur upon application such as when using rotary screen printers and the like.
  • Finishing agent-containing compositions for utilization in the present invention are known in the art and typically comprise a finishing agent and an aqueous or organic liquid carrier medium along with other known, optional ingredients.
  • finishing agents which may be utilized in the treatment of textiles according to the present invention include coloring agents, dyes, pigments, durable press agents, soil release agents, weighting agents, flame retardants, water repellents, softeners, and the like.
  • Foamable, liquid compositions containing such finishing agents, and methods of preparing foams therefrom, are known in the art.
  • the application of the first finishing agent-containing composition may comprise printing the textile with a pre-selected pattern in accordance with known procedures, e.g., by use of an intaglio printing cylinder or a rotary screen printer.
  • the first composition may be a conventional liquid printing composition, a foamed printing composition or a powdered composition.
  • a foamed composition, with another finishing agent is applied to the textile prior to fixation of the first applied finishing agent to the printed textile.
  • the process of the present invention will typically be utilized for the serial application of two or more differing types of finishing agents to a textile, e.g., a colorant and a water- repellent or a colorant and a durable press agent, although numerous other combinations exist.
  • finishing agents e.g., a colorant and a water- repellent or a colorant and a durable press agent, although numerous other combinations exist.
  • textile material is intended to include, without limitation, fabrics made from threads, yarns, woven or knitted goods, resin bonded mats of fibres, and the like.
  • the second, serially applied fabric finishing agent is applied to the textile in the form of a foam while the textile still contains a first finishing agent-containing composition (either foam, liquid or powder).
  • a first finishing agent-containing composition either foam, liquid or powder.
  • some liquid may be removed by virtue of passage of the textile through conventional squeeze rolls prior to passing to the second serial application step.
  • the generally preferred manner of collapsing the foam is accomplished by the printing screen or print roller at the instant the foam is applied to the fabric.
  • the textile to which the second finishing agent composition is applied will have about 10 to 65% liquid, by weight, associated therewith.
  • a roll of fabric 10 travelling in the direction indicated by the arrow, is passed by suitable conveying means to a bath 12 containing a pre-prepared liquid e.g., aqueous or organic liquid, solution or dispersion containing an appropriate finishing agent, e.g., a dye material to color the fabric.
  • the dyed fabric is then passed through squeeze or compression rollers 14 and 16 which serve to remove some of the liquid contained in the fabric by virtue of its passage through the solution or dispersion. Without any further liquid removal, i.e., before complete drying, the dyed fabric is coated with a foamed finishing agent composition.
  • a foamable liquid composition comprised of liquid, foaming agent and finishing agent, e.g. a durable press agent, is formed into a foam in foamer 18.
  • Foamer 18 may be any type foaming device conventionally utilized in the art, e.g., Oakes, Godwin card, Kitchenaid, etc.
  • the foamed composition is transferred through line 22 by pump 20 to knife 24. At this point the foamed composition is coated onto the dyed fabric to produce a coated fabric 26.
  • the coated fabric 26 then goes through nip rollers 28 and 30 to compress and collapse the foam and achieve penetration of finishing agent into the fabric. Such foam collapse may also be achieved by the application of vacuum, or a combination of vacuum and padding.
  • the impregnated fabric is conveyed through a fixation means 32 which may be any of those conventionally known in the art.
  • the fixed fabric is then wound on to take-up roll 34.
  • FIG. 2 An alternative embodiment of the process of the present invention is shown in Fig. 2.
  • a roll of fabric 40 travelling in the direction of the arrow by suitable conveying means, is coated with a first foamed fabric finishing agent composition.
  • a foamed composition is prepared by foaming a suitable composition, e.g., a dye- containing foamable composition, in foamer 42.
  • the foamed composition is pumped by pump 44 through line 46 to a rotary printing screen 48 at which a predetermined pattern is applied to the fabric.
  • a rotary printing screen 48 As mentioned previously, with such a printing screen, the foam is caused to collapse upon application. If a procedure is employed in which the foam is not collapsed upon application, the so-coated fabric 50 is then passed over vacuum or padding device 56 or a combination of the two which serves to collapse the foam but which does not effect liquid removal from the fabric.
  • the so treated fabric 66 is then coated with a second foamed finishing agent composition, formed by foaming a suitable composition, e.g., a durable press-containing foamable composition, in foamer 58.
  • the second foamed composition is transferred by pump 60 through line 62 to knife 64 where it is coated on the fabric.
  • the so-coated fabric 68 is then padded by passing through nip rollers 70 and 72 to collapse the foam and deeply penetrate the finishing agent into the fabric.
  • the fabric is then conveyed to a fixation means 74 and wound on take-up roll 76.
