Description
all of Charlotte, N.C., assignors to Celanese Corporation of America, New York, N.Y., a corporation of Delaware No Drawing. Filed Apr. 20, M61, Ser. No. 104,229 12 Claims. (Cl. fi-SS) This invention relates to the coloring of polyolefin materials, particularly textile materials made of polyolefins.
Considerable difliculties have been encountered by the art in the dyeing of polyolefin materials. Polyolefin materials such as polypropylene or polyethylene materials are known in the art as not readily adaptable to being colored by conventional dyeing techniques.
It is an object of this invention to provide a novel dyeing process for polyolefin materials.
It is a further object of this invention to provide a dyeing process for textile materials comprising polyolefin fibers.
Other objects of this invention will become apparent from the description and claims which follow wherein all proportions are by weight unless otherwise indicated.
In accordance with one aspect of this invention, a polyolefin textile material, e.g., a fabric comprising polyolefin fibers is impregnated with a composition comprising a dyestufi? for polyolefins and a dyeing assistant in an aqueous medium and heat is applied to said material.
The process of this invention has been found to be effective in dyeing materials made of polyolefins comprising olefin monomers such as 4-methyl-l-pentene and 3-methyl butene and particularly polyethylene and polypropylene materials. The materials comprising the polyolefins may be polyolefin fibers or films comprising polyolefins. This process is particularly effective in dyeing textile materials such as woven fabrics comprising polyolefin fibers. In these fabrics, the polyolefin fibers may be present alone or as blends with other fibers including cellulosic fibers such as cellulose esters including cellulose acetate and triacetate, linen, ramie, sisal and rayon; animal fibers such as wool, silk and other man-made fibers such as polyamides, polyesters, polyacrylic and nytril fibers. In such blends it is preferable that the polyolefin fibers comprises at least of the blend.
The term textile material as used in this specification includes, fibers both continuous and staple, tow, yarn as well as fabrics including knit and other interlaced fabrics as well as non-woven fabrics.
It is preferable that the polyolefin-containing textile materials be impregnated with the aqueous coloring composition by immersing the textile materials in a bath of the aqueous coloring composition. A particularly suitable immersing method is by padding, which is passing the textile material through the bath and then through squeeze rollers. The temperature of the coloring bath is desirably at least about 100 F. and most preferably from 160 to 200 F. The time of immersion of the fabric is preferably from 0.5 to 50 seconds and most preferably from 2 to 10 seconds.
Hydrogenated aromatic compounds have been found to provide excellent dyeing assistants in the practice of this invention. Such hydrogenated aromatics include hydrogenated mononuclear aromatic compounds such as cyclohexene and cyclohexanol and preferably hydrogenated polynuclear aromatics, particularly hydrogenated polynuclear aromatics with condensed nuclei, e.g., hydrogenated naphthalene including tetrahydronaphthalene and decahydronaphthalene.
In addition to hydrogenated aromatics, the following provide valuable dyeing assistants: polynuclear aromatics diphcnyl; phenyl and butyl Cellosolves; butyl benzoate as well as triethyl phosphate.
The dyeing assistant preferably comprises from 1 to 20% of the coloring composition and most preferably from 2 to 10% of said composition.
The coloring composition preferably has an aqueous medium. The coloring composition may be advantageously in the form of a dispersion of the dyestuff such as an aqueous emulsion or it may be dissolved in the aqueous medium. Where the coloring composition is inthe form of a dispersion, an emulsifying agent is preferable. Conventional emulsifying agents such as soaps, salts of long-chain carboxylic and sulfonic acids, alkylated aromatic sulfonic acids, and salts of long-chain amines may be used. The emulsifying agent preferably comprises from 0.1 to 4% and most preferably from 0.25 to 2% of the coloring composition.
For best results the dyeing assistant must be water soluble or readily emulsifiable in the aqueous dye me dium. The emulsifying agent used for the dye may also act as the emulsifying agent for the dyeing assistant.
The process of this invention is effective in dyeing hydrophobic polyolefins, e.g., olefins characterized by an absence of functional groups as well as in dyeing difficultly dyeable polyolefins characterized by an absence of dye-receiving functional groups.
The process of this invention has its greatest utility in dyeing high density polyolefins, preferably directed polyolefins. Such directed polyolefins are polymers in which the molecules are directed and in which polymerization follows a regular pattern. Such polyolefin resins are produced, for example, by the low pressure polymerization aliphatic olefins and preferably, of ethylene or propylene with selected catalysts. Polymers produced by directed polymerization have higher densities, higher degrees of crystallinity, higher melting points, higher tensile and impact strengths than conventional polymers from the same olefinic monomers. Directed or linear polyethylenes also known as high density polyethylenes have melting points between and C., as contrasted to nondirected polyethylenes which melt at about 100 C. Directed or polypropylene or polypropylene having a regular steric pattern melts at even higher temperatures, of the order of C. to C., e.g., isotactic and syndiotatic polypropylene.
While heat may be applied to the textile material during impregnation, it is preferably also applied after the impregnation or padding step. The impregnated material is preferably heated at a temperature from about to 280 F. and most preferably from 220 to 260 F. The fabric is maintained at such temperatures for from 2 to 60 seconds and most preferably from 5 to 30 seconds.
An apparatus which has been found to be particularly suitable for carrying out the heating of the wet impregnated fabric is the reactor described in German Patent 1,057,055. It operates on the basis of permitting the impregnated liquid to partially evaporate in a constricted zone. The partial evaporation increases the pressure in the zone to superatmospheric pressure, thereby permitting higher temperatures than at atmospheric temperature. Other suitable apparatus includes the Hunter Pressure Lola Machine, wherein the padded material passes continuously through a steam atmosphere under pressure and a pad steam range in which the impregnated fabrics are heated by applying steam to said fabrics.
It is preferable that the dye comprises from 0.05 to 8% and most preferably from 0.05% to 5% of the whole aqueous coloring composition.
Some of the disperse dyes listed in Colour Index, 2nd Edition, pages 1659-1741, may be used. Further, one
sltilied in the art may find solvent dyestuffs among those Patented June 15, 1965;

listed on pages 2817-2905 which would give satisfactory colorations.
The following dyes give desirable results: Ponsol Flavone GCD (CI, 2nd Ed, Part -Il, No. 67,300). and
V AmacelYellow G (CI, 2nd Ed, Part II, No. 11,855).
In addition, it has been found that particularly good results are obtained with gasoline soluble dyes. Such dyes include Calco Gas Orange NC. (Cl, 2nd Ed, Part II, No. 12,055), Calco Gas Rocket Red (CI, 2nd Ed, iart II, No. 26,120).
. The following examples will serve to better illustrate the practice of this invention:

The fastness to light and washing was not as good as that of Example I.
Example V 'A fabric of the type described in Example Ti was passed through an aqueous dispersion having the same composition as that of Example I, maintained at 77 F. The time of immersion of the fabric in the dispersion was 15 seconds. After impregnation as aforesaid, the impregnated fabric was steamed at 212 F. for a period of 60 seconds. The fabric was then passed through two boxes of boiling Water and then through two additional boxes containing water at 208 F. and containing chip soap. The fabric was then rinsed in hot water and dried.
The resulting dyed product had a red shade and was fast to light and washing.
A plain woven fabric made of yarns of spun polypropylene was passed through an aqueous dyebath comprising O.2% of a gasoline soluble blue dye, 10% tetrahydronaphthalene and 5% of Emkalar Base E55 (an emulsifier blend of anionic surface active agents) maintained at 77 F. The total immersion time of the fabric was 10 seconds. The fabric was then passed through a Monforts Reactor in which it was maintained at 240 F; for 15 seconds. The dyed fabric was then washed in an aqueous solution having one gm. per liter of soap at F. for 10 minutes. The fabric was dyed a blue shade which had good fastness to light and washing.
