Description
METHOD FOR TREATING TEXTILE MATERIALS
This invention relates to textile materials and, more particularly, to the application of finishing agents to textile materials.
5 Conventionally, the treating of textile materials with finishing agents, e.g., coloring agents or dyes, resins, softeners, flame retardant agents, soil release agents and the like involves a procedure wherein the finishing agent is either dissolved or dispersed in a suitable li- o quid medium carrier such as an aqueous or organic li¬ quid, and then applied to the textile, such as by pas¬ sing the textile through a bath or vat containing the solution or dispersion. Thereafter, the carrier is re¬ moved from the fabric, usually by evaporation with or 5 _ without heat. Since only a small amount of the fin¬ ishing 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 o medium whichmust be removed from the fabric. Conse¬ quently, a substantial amount of the cost incurred in.such processes resides in the liquid medium removal s ep.
5 For many .textiles it is desired to apply more than one
OMPI • /j_. IPO .
finishing agent thereto. For example, it may be de¬ sirable 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 rela- 5 tively 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 o then dried; and the colored textile then treated with a further fabric finishing agent in a conventionalman¬ ner and then re-dried.
In the foregoing process, the disadvantages earlier 5 described as being associated with the conventional utilization of large quantities of liquid medium in the application of finishing agents are necessarily multiplied. In an effort to avoid the difficulties involved with large amounts of liquid and the high o cost of liquid removal processes, it has been attem¬ pted to conduct the serial application of finishing agents to a textile without intermediate drying of the textile after each application. However, this manner of operation itself leads to serious problems. Thus, 5 when the wet textile to which a first finishing agent solution or dispersion has been applied is brought in¬ to contact with a second liquid finishing agent com¬ position, e.g., when the wet textile is passed through a bath thereof, the liquid associated with the textile o from the first application serves to dilute or other¬ wise alter the composition of the second finishing agent solution or dispersion. It is thereby nearly impossible to accurately control the application of specified quantities of the second finishing agent to 5 the textile, even with the utilization of complicated measuring devices and bath replenishment techniques.
SUMMARY OF THE INVENTION
It is accordingly an object of the present invention to provide a process for treating a textile with more than one finishing agent.
A further object of the present invention is to provide a serial process for treating a textile with a least one finishing agent which does not require intermediate fixation of the textile prior to application of a foam composition thereover. o
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. 5
These and other objects are achieved by the provision of a process wherein a textile is first treated with a finishing agent-containing composition and, prior to any significant drying or fixation (i.e., complete re- o moval 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, if 5 desired.
The treatment of textiles in accordance with the pre¬ sent invention has the advantage of eliminating costly liquid removal procedures between application of fin- o ishing agents. Moreover, it has been found that appli¬ cation of the second finishing agent in the subse¬ quently applied foamed composition avoids the earlier- referred to dilution effect arising.from conventional
OMPI
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 5 the need for passing the textile through a bath or vat containing the liquid finishing agent composition.
In accordance with the present invention, the applica¬ tion of the first finishing agent-containing composi- o tion 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. However, according to a pre¬ ferred embodiment of this invention, the first finishin 5 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 o 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 typi- 5 cally comprise a finishing agent and an aqueous or or¬ ganic liquid carrier medium along with other known, optional ingredients.
For the case where the finishing agent-containing com- o position is applied as a foam, the preparation and formulation of such foamed compositions is described in the commonly-assigned application of Gregorian., and Namboodri, Serial No. 584,389, now U.S. Patent No. , incorporated herein by reference. These 5 foamed compositions are prepared by foaming a mixture
comprised of finishing agent, liquid medium and a foam¬ ing agent (foam stabilizer) to a blow ratio of from about 2:1 to about 2o:1 to result in a foamed composi¬ tion having a foam density in the range of from about 5 o,5 gm/cc to about o.o5 gm/cc.
The various finishing agents which may be utilized in the treatment of textiles according to the present in¬ vention include coloring agents, dyes, pigments, dura-
-jo ble 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 there¬ from, are extensively described in detail in the above-
15 mentioned application Serial No. 584,389.
In specific embodiments of the present invention, the application of the first finishing agent-containing composition may comprise printing the textile with a
2o pre-selected pattern in accordance with known procedu¬ res, 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. After
25 application, a foamed composition, with another fin¬ ishing agent, is applied to the textile prior to fixa¬ tion of the first applied finishing agent to the prin¬ ted textile.
3o 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 combina-
35 tions exist.
OMPI
As utilized herein, 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.

According to this invention, the second, serially applied fabric finishing agent is applied to the texti¬ le in the form of a foam while the textile still con¬ tains a first finishing agent-containing composition o (either foam, liquid or powder). Thus, as utilized herein, application of the second composition without prior fixation of the textile is intended to describe and embrace processes wherein the textile has not been fully dried after application of the first composition. 5 Hence, it is possible according to this invention that varying degrees of liquid removal, short of complete or near-complete drying, from the textile can be per¬ formed before application of the second, foamed compo¬ sition, although the economic advantages of the present o invention necessarily decrease in proportion to the de¬ gree of such an intermediate liquid removal step. More¬ over, a certain degree of liquid removal from the textile may occur simply as a result of normal proces¬ sing prior to application of the second, foamed compo- 5 . sition. For example, 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. In the case of foam printing, the generally preferred manner of collapsing the foam is o accomplished by the printing screen or print roller at the instant the foam is applied to the fabric.
In- general, the textile to which the second finishing agent composition is applied will have about 1o to 65% 5 liquid, by weight, associated therewith.

BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is as schematic representation of an embodiment depicting the process of the present invention wherein 5 the first liquid and finishing agent-containing compo¬ sition is applied as a solution or dispersion.
Fig. 2 is a schematic representation of. an embodiment of the present invention wherein the first finishing Q agent-containing composition is applied in the form of a foam.
DESCRIPTION OF THE PREFERRED EMBODIMENT
5 The present invention is more fully described with re¬ ference to the description of the drawings and the Examples which follow.
With reference to Fig. 1 , a roll of fabric 1o, travel- o ling 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 finish¬ ing agent, e.g., a dye material' to color the fabric. 5 . The -dyed fabric is then passed through squeeze or com- - pression 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 liq'uid removal, i.e., before complete drying, o the dyed fabric is coated with a foamed finishing agent composition. Thus, a foamable liquid composition com- ■ prised of liquid, foaming agent and finishing agent, e. g.' a durable press agent, is formed into a foam in foa er 18. Foamer 18 may be any type foaming device 5 conventionally utilized in the art, e.g., Oakes, God¬ win card', Kitchenaid, etc.
OMPI . WIPO
The foamed composition is transferred trough line 22 b pump 2o to knife 24. At this point the foamed composi¬ tion is coated onto the dyed fabric to produce a coate fabric 26. The coated fabric 26 then goes trough nip 5 rollers 28 and 3o to compress and collapse the foam an achieve penetration of finishing agent into the fabri Such foam collapse may also be achieved by the applica tion of vacuum, or a combination of vacuum and padding Thereafter, the impregnated fabric is conveyed through o a fixation means 32 which may be any of those conven¬ tionally known in the art. The fixed fabric is then wound on to take-up roll 34.
An alternative embodiment of the process of the presen 5 invention is shown in Fig. 2. A roll of fabric 4o, travelling in the direction of the arrow by suitable conveying means, is coated with a first foamed fabric finishing agent composition. Such a foamed composition is prepared by foaming a suitable composition, e.g., a 0 dye-containing foamable composition, in foamer 42. The foamed composition is pumped by pump 44 through line 4 to a rotary printing screen 48 at which a predeter¬ mined pattern is applied to the fabric. As mentioned previously, with such a printing screen, the foam is 5 caused to collapse upon application. If a procedure is employed in which the foam is not collapsed upon appli cation, the so-coated fabric 5o is then passed over va cuum or padding device 56 or a combination of the two which serves to collapse the foam but which does not o 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-containi 5 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 then passes through nip rollers 7o . and 72 to collapse the foam and deeply penetrate the 5 finishing agent into the fabric. The fabric is then conveyed to a fixation means 74 and wound on take-up roll 76.
In the foregoing embodiments, the foamed finishing Q agent composition may also be applied by spraying or blowing it through a nozzle onto the fabric.
The following Examples illustrate various specific features of the process of the present invention. 5
