Definitions

  • the present invention relates to an improved finishing composition for filaments, yarns and other textile materials.
  • the present invention further relates to an improved process for utilizing the novel finishing composition and the textile products thereof.
  • finishing compositions In the formation of textile materials from'melt spun polypropylene it is normally necessary to apply a finishing composition. to the filaments, yarns and other textile embodiments thereof to make such materials more amenable to the various operations to which they are subjected during processing, for example, spinning, winding, yarn-forming, weaving, knitting, etc., and to improve the properties of the finished products.
  • the finishing composition In the processing of the textile materials, the finishing composition is intended to reduce friction between the yarn and various pieces of equipment with which it comes into contact, such as guides, rollers and the like, and in both the processing and use of the textile materials to reduce friction between the fibers themselves, to prevent fiber and yarn breakage and to minimize excessive attraction or repulsion of the filaments caused by electrostatic charges. Accordingly, such finishing compositions usually contain a lubricant and an antistatic agent. Various other additives such as bactericides, corrosion inhibitors, etc. may also be added to the finishing composition.
  • thermoplastic materials respond to finishing compositions in the same manner, not all combinations of finishing agents are compatible with one another and not all finishing agents are compatible with stabilizers and the like added to the thermoplastic melt.
  • polypropylenes do not respond to certain lubricants in the same manner as other thermoplastic fiber-forming materials, particularly when the polypropylenes contain less than the normal amounts of stabilizing agents, such as antioxidants, or when they contain specific types of stabilizing agents.
  • stabilizing agents such as antioxidants
  • stabilizing agents such as antioxidants
  • textile lubricants have an antagonistic effect on certain stabilizers included in polypropylene melts.
  • An object of the present invention to provide an improved textile finish composition, a process utilizing the same and the products thereof.
  • a further object of the present invention is to provide an improved textile finish composition including a textile lubricant and an antistatic agent, a process utilizing the same and the products thereof.
  • Yet another object of the present invention is to provide an improved textile finish composition which is useful in the treatment of polypropylene textiles, a process for the utilization thereof and the products thereof.
  • Another and further object of the present invention is to provide an improved textile finishing material for treating polypropylene textiles containing certain types of antioxidants, a process utilizing the same and the products thereof.
  • Yet another object of the present invention is to provide an improved finish composition adapted to improve the thermal stability of polypropylene textiles, a process for utilizing the same and the products thereof.
  • a still further object of the present invention is to provide an improved textile finish composition adapted to improve the thermal, light and/or color stability of polypropylene textile materials, a process for utilizing the same and the products thereof.
  • a textile finish composition for improving the stability of polypropylene textile materials comprising, an ethoxylated textile lubricant, in amounts sufficient to impart lubricating properties to the composition, and an antistatic agent comprising phosphate esters, in an amount sufficient to impart antistatic properties to the composition and increase the stability of the polypropylene textile materials.
  • the improved finish composition is particularly effective in the treatment of polypropylene textile materials containing less than the normal amounts of stabilizers and still more specifically stabilizers including hindered phenols.
  • the method of preparing an as-spun polypropylene textile material includes melt spinning a polypropylene, particularly a polypropylene melt containing a hindered phenol antioxidant, applying the specified finish composition to the filamentary materials, forming a yarn from said filamentary materials and packaging the yarn.
  • the yarn may also be draw-twisted before or after the packaging of the yarn.
  • Such draw-twisted yarns may be woven into products particularly suitable for use as dye bags, laundry bags, and the like.
  • Figure 1 of the drawings illustrates the process for preparing an as-spun yarn in accordance with the present invention
  • Figure 2 illustrates one embodiment of a process for draw-twisting the yarns produced by the process of Figure 1.
  • Ethoxylated lubricants have heretofore been found to be highly superior to conventional textile lubricants, particularly when utilized in finish compositions for treating melt spun thermoplastic materials and particularly polypropylenes. Accordingly, it is highly desirable to utilize these synthetic lubricants in the finish composition.
  • melt spun polypropylene textile materials are in some way deleteriously affected by the use of ethoxylated textile lubricants.
  • the ethoxylated textile lubricants have a tendendy to reduce the thermal, light and/or color stability of the textile materials both during the processing thereof and in the end products produced.
  • a stabilizer system including a tris-(4-hydroxybenzyl)isocyanurate, a substituted pentaerythritol diphosphite, a trihydrocarbyl thio- phosphite and optionally thiomethylene phenol. It has further been found that, when hindered phenols are included in stabilizer systems for the polypropylene melt, some antagonistic reaction occurs between an ethoxylated lubricant and the hindered phenol which results in decreasing.the thermal, light and/or stability of the textile products.
  • the stability of polypropylene textile materials can be substantially improved. It has also been found that, in many cases, the color stability of such polypropylene textile materials can also be improved by the specified combination of synthetic lubricant and antistatic agent.
  • the finish composition optionally, but desirably, contains minor amounts of a bactericide and may also contain minor amounts of other additives such as corrosion inhibitors and the like.
  • a polypropylene melt particularly including minor amounts of a stabilizing system and still more particularly a stabilizing system including at least one hindered phenol, is melt spun, the subject combination of synthetic lubricant and antistatic agent is applied thereto, the filamentary materials are formed into a yarn and the yarn is then wound up to form a package.
  • the novel finish composition may be applied to the textile materials at any time during the processing thereof, it is preferably applied to the filaments as soon as they have set, so that the full benefit of the stabilizing properties thereof can be realized during the later processing thereof.
  • the yarnsthus produced are draw-twisted and again packaged.
  • the draw-twisting can also be applied in a continuous process prior to the initial winding or packaging of the yarn.
  • the draw-twisted yarns have been found to be highly effective for the production of dye bags, laundry bags and the like when woven and formed into appropriate articles.
  • thermoplastic textile materials to which the present invention is particularly directed are homopolymers of propylene and copolymers of propylene and another aliphatic 1-olefin containing 2 to 8 carbon atoms, in which the comonomer constitutes up to about 20 mol percent of the copolymer.
  • the synthetic lubricants utilized in accordance with the present invention include any of the known ethoxylated' lubricants such as polyethylene glycols, mixed polyethylene- polypropylene glycols, monoalkyl esters of mixed polyethylene-polypropylene glycols, ethoxylated esters of fatty acids, rosin acids and tall oil acids, ethoxylated castor oils, ethoxylated hydrogenated castor oils, etc.
  • the ethoxylated lubricants includes, ethoxylated aliphatic alcohols, ethoxylated alkylphenols, ethoxylated sorbitan (anhydrosorbitol) esters, ethoxylated sorbitol esters, ethoxylated glycerol esters, ethoxylated pentaerythritol esters, ethoxylated fatty acids, ethoxylated fatty acid amides, ethoxylated-propoxylated fatty acids, ethoxylated-propoxylated fatty acid esters, ethoxylated-propoxylated castor oils, ethoxylated- propoxylated hydrogenated castor oils, ethoxylated-propoxylated aliphatic alcohols, ethoxylated-propoxylated alkyl phenols, etc.
  • Presently preferred ethoxylated lubricants include the random copolymers of the monobutyl ether of poly(oxyethylene- oxy-1,2-propylene) having viscosities in terms of Saybolt Universal Seconds (SUS) at 100° F (38 0 C) ranging from about 170 to about 5100 and even more preferably from about 250 to about 3500, the methyl ether of poly(oxyethylene-oxy-1,2-propylene) laurate wherein the number of moles of combined ethylene oxide, is about 7 and the number of moles of combined propylene oxide is about 2, and the iso- dodecyl ether/poly(oxyethylene) adduct wherein the number of moles of combined ethylene oxide is about 6 per mole hydrophobe.
  • SUS Saybolt Universal Seconds
  • the hindered phenols are utilized as thermal stabilizers or antioxidants.
  • Such materials are known in the art.
  • Typical of such stabilizers are 2,6-di-t-butyl-4-methylphenol (BHT); octadecyl[3-(3,5-di-t-butyl-4-hydroxyphenyl)] propionate (Irganox 1076, Ciba-Geigy Chemical Co.); tetrakis[methylene(3,5-di-t-butyl-4-hydroxyhydrocinnimate)] methane (Irganox 1010, Ciba-Geigy Chemical Co.), di-n-octadecyl(3,5-di-t-butyl-4-hydroxybenzyl) phosphonate; 1,3,5-trimethyl-2,4,6-tris(3,5-di-t-butyl-4-hydroxy
  • the phosphate-type antistatic materials utilized in accordance with the present invention include hydrocarbyl phosphate esters, ethoxylated hydrocarbyl phosphate esters, partially hydrolyzed hydrocarbyl phosphate esters or their salts.
  • hydrocarbyl is meant a hydrocarbon radical selected from the alkyl, cycloalkyl, aryl and combinations thereof such as alkylauryl,etc., containing from 1 to about 20 C atoms. Usually a mixture of di- and monoalkyl esters are utilized but the composition is also effective when completely esterified phosphoric acid compounds are employed.
  • the use of the phosphate-type antistatic agents of the present invention are quite effective in inhibiting color formation during gas fired heat treatments if the polypropylene melt composition contains a hindered phenol as an antioxidant. It has further been found that the inhibition of color formation is influenced by the pH and the neutralizing cations employed. The lower the pH the less color produced. Preferably, the pH is maintained between about 3 and about 9 and preferably between about 4 and about 7.
  • the preferred phosphate-type antistatic materials are the partially neutralized acid esters of phosphoric acid or the equivalent partially hydrolyzed triesters of phosphoric acid.
  • the present order of neutralizing cations has been found to be ammonium, mono-, di-and triethanolammonium,lithium, sodium and potassium. The potassium was found to be the least desirable, although useable in accordance with the present invention.
  • the finish composition of the present invention alsodesir- ably contains a bactericide such as 6-acetoxy-2,4-dimethyl- m-dioxane (Givgard DXN( R ), Givaudan Corp., Clifton, NJ).
  • a bactericide such as 6-acetoxy-2,4-dimethyl- m-dioxane (Givgard DXN( R ), Givaudan Corp., Clifton, NJ).
  • the relative amounts of the ingredients of the finish composition of the present application are not particularly critical.
  • the ethoxylated lubricant should of course be used in amounts sufficient to lubricate the textile materials and the antistatic agent in amounts sufficient to prevent undesirable electrostatic charges from building up in the textile materials.
  • the ethoxylated lubricant is utilized in amounts between about 50 and about 98 percent by weight of the finish composition and most desirably between about 60 and 95 percent by weight of the composition.
  • the balance of the finish composition is preferably the antistatic agent in amounts between about 2 and 50 percent by weight and most desirably between about 5 and 40 percent by weight of the finish composition
  • the bactericide may be present in amounts between about O and about 1.0 percent by weight of the final composition and like minor amounts of other suitable additives may be included, such as corrosion inhibitors.
  • the polypropylene melt is extruded from a plural orifice spinneret 2, of conventional design. While spinneret 2 is shown in the drawings as producing a single threadline it is obvious that the spinneret may produce two or more threadlines.
  • the filaments from spinneret 2 are passed through a conventional quench zone 4 where the filaments are cooled and set. Finish is applied by conventional finish applicator means 6 which may take any appropriate form. For example, a "kiss" roll may be utilized to apply finish to the filaments as a gathered threadline or yarn or as a band spread across the finish roll.
  • a slot type finish applicator could also be utilized, the only requirement being that the finish be uniformly applied to the filaments or yarn.
  • the yarn is then wound on an appropriate conventional winder 8 to form a yarn package 10.
  • Appropriate guides, guide rolls, crcdet rolls, and the like will of course be utilized.
  • the process as illustrated in Figure 1 produces a yarn in its as-spun state. However, it is also possible to draw-twist the yarn. before winding the same on package 10. Whether draw-twisting is practiced as a part of the spinning operation will depend to some extent upon whether the yarn is partially oriented yarn or a conventional undrawn yarn. Normally it is considered that winder takeup speeds in excess of about. 1500 meters per minute will produce a partially oriented yarn whereas takeup speeds of less than about 1500 meters per minute, for example about 800 meters per minute, produce an unoriented or undrawn yarn.
  • Figure 2 illustrates a preferred draw-twisting operation in accordance with the present invention.
  • yarn is withdrawn from yarn package 10 by means of the draw means 12 made up of conventional draw rolls, 12a and 12b, respectively.
  • twist means 14 conventionally applies by means of a flyer 16 as it is wound on package 18.
  • any appropriate drawing and twisting apparatus may be utilized. It will also be apparent to one skilled in the art that the system would include appropriate guides, guide rolls, draw heaters, etc.
  • the draw-twisted yarn when converted into an appropriate fabric and formed into a bag or the like has been found to make excellent dye bags, laundry bags and the like.
  • the resultant products have superior temperature stability compared with conventionally finished textile materials of polypropylene and to conventional dye bag textiles.
  • certain of the polypropylenes have been found to have superior inhibition to color formation as compared with conventionally finished polypropylenes and commercially available dye bag textiles.
  • a polypropylene melt composition was prepared by adding to the polypropylene 0.05 parts by weight per 100 parts of polypropylene (phr) of calcium stearate, 0.3 phr tris(3,5-di-t-butylhydroxybenzyl)isocyanurate, 0.1 phr hydrolysis resistant distearyl pentaerythritol disphosphite 0,1 phr trilauryl trithiophosphite and about 0.375% titanium oxide.
  • the polypropylene had a melt flow of 12 and when combined with the specified stabilizing system is designated hereinafter as resin B.
  • finish I contains the following:
  • finish II contains the following:
  • the yarn was knitted into a sleeve and the sleeve trimmed so that the yarn could be easily unravelled for sampling.
  • the sleeve weighing about 5 grams, was placed in a 500 milliliter, flat bottom flask fitted with a water cooled reflux condenser. 200 milliliters of a 0.2% AATCC Standard Soap Solution was boiled under reflux for 6 hours after which time the sleeve was removed, rinsed free from the solution and squeezed dry. The sleeve was then dried for 15 hours at 130° C in an electrically heated, forced air oven to complete the cycle. About a 5 foot sample of the yarn was removed from the sleeve and tested for strength and elongation retention on an Instron Tensile Tester after 3, 5 and 8 cycles, respectively.
  • the ultraviolet stability was measured by exposing 2" by 3" knitted sleeves mounted on black backed Atlas mounting fadeometer cards. Degradation is either when the fabric tears or when the fabric flakes while being gently scratched with a fingernail. Usually if the sleeve is of fine denier yarn the fabric will tear and it is the sleeve surface closest to the black backing which tears before the surface closest to the arc. With heavier denier fabrics flaking of the surface facing the arc usually occurs before the fabric can be torn. Table 3 below gives the results of these tests.
  • finishes containing an ethoxylated lubricant and the phosphate-type antistatic agents, in accordance with the present invention were vastly superior to finishes containing only ethoxylated lubricants and balanced finishes containing the ethoxylated lubricants and antistatic agents other than the phosphate-type antistatic agents utilized in accordance with the present invention, which other lubricant compositions have been highly successful as finishes for other textile materials.
  • finish compositions of the present invention were tested for use as dye bag yarns.
  • the yarns were made from a stabilized polypropylene melt designated resin B in the above examples and were finished with either finishes I or II as specified in the previous examples.
  • the finish was metered onto the yarn with no problems.
  • the yarn was draw-twisted using a standard 1680/280 yarn process. Eight positions of a draw twister processing 1680/280 yarns were used. Again no problems were seen. The yarns were then coned into ten ounce packages and knitted into dye bags for testing.
  • the mock dye cycle test is the same as the previously described laundering cycle except that the treating solution was 200 milliliters of the following:
  • the GMC-Arc fadeometer exposure test was substantially the same as the previously described carbon arc fadeometer test.
  • the accelerated gas fade color development test simulates processes which involve heating and curing br drying in gas fired ovens. It also produces colors which have been seen transiently under the same kinds of storage conditions which have not heretofore been simulated.
  • the test provides for a 10 minute heating cycle at 130° C followed by a 2-hour treatement in an atmospheric fume chamber (AATCC test method 23-1975).
  • the toughness is defined as:
  • the toughness factor is used as the critical criterion because it balances the elongation and the tenacity into a property which has been found to be the equivalent to performance in actual practice.
  • the dye bag yarns in accordance with the present invention are whiter than the control yarn and than the commercial dye bag yarn; it remains whiter in the cycling test, the thermal stability tests and in actual laboratory storage experiments. Accelerated gas fade tests showed no pinking problems with the dye bag_yarns of the present invention and no such problems have been observed with the control yarns. In 3-cycle gas fade tests, the yarns show quite a severe color development. However, this is not believed to be a problem in dye bag yarns since the only place it will show up is after long storage in a high nitrogen oxide atmosphere. The dye bag yarns would not be subjected to such an environment since legislation has essentially ruled out this kind of contamination.
  • Tests were also conducted utilizing a 12 melt flow polypropylene melt composition stabilized with 0.30% distearylthiodipropionate, 0.10% tetrakis(methylene(3,5-di-t-butyl-4-hydroxy hydrocinnimate)] methane and 0.05% calcium stearate and a 12 melt flow polypropylene having a stabilizer system; comprising, 0.30% distearylthiodipropionate, 0.10% tetrakis/methylene(3,5-di-t-butyl-4-hydroxy hydrocinnimatef methane (Irganox 1010, Ciba-Geigy), 0.05% calcium stearate and 0.10% hydrolysis resistant distearyl pentaerythritol diphosphate Weston 619, a product of Borg-Warner Chemicals, Parkersburg, W.Va.
  • Both of the stabilizing systems utilized in the polypropylene melt composition are seen to contain hindered phenols. It was found that about 2% of an ethoxylated textile lubricant applied to these textile materials will reduce the thermal stability at 130° C from 400 hours to 60 hours or from 1500 hours to 200 hours depending on the denier of the product. However, the presence of about 10% to 50% of the phosphates of the present invention and the same ethoxylated lubricants the textile materials recover substantially all of the strength thus lost.
  • the finish compositions of the present invention contains a hindered phenol. Specifically, inhibition of color formation during gas fired heat treatments is improved. For example, yarns spun from resin formulations B and C above when heated to 130 0 C and exposed for 2 hours in a nitrogen oxide gas fade oven will turn pink. This pink color will be increased in the presence of an ethoxylated textile lubricant- containing finish-unless the finish has added thereto a phosphate type antistatic agent as taught in the present invention.
