Definitions

  • the present invention relates to the sizing of textile yarns, such as those composed wholly or partly of Dacron, with tough, flexible, water-soluble polymers which are the reaction products of polyalkylene ether glycols and aryl diisocyanates.
  • Another object of the invention is the provision of a synthetic size which may be easily desized with plain Water and dumped into streams without seriously polluting them.
  • Another object of the invention is the provision of an inexpensive method of advantageously sizing and desizing textile yarns while substantially eliminating stream pollution problems.
  • novel polymers of this invention are particularly characterized by their water-solubility and their filmforming properties. They are readily water soluble, making them easy to apply to textile yarns as a size, and they retain their solubility so that desizing may be accomplish'ed by a simple water wash.
  • the films formed from water solutions of these new polymers are very tough and flexible and strong, especially as contrasted with the brittle films of the polyethylene ether glycol polymers alone and the prior art materials produced with water-insoluble reaction products of polyalkylene ether glycols and aryl diisocyanates, which materials are sometimes rubbery and sometimes crumbly.
  • one molar equivalent of a substantially anhydrous polymer of polyalkylene ether glycol having a molecular weight of from about 750 to 20,000 is catalytically reacted with from about 1 to 2 molar equivalents of an aryl diisocyanate (in practice slightly more than 1 mol is required and less than 2 mols is needed to avoid the danger of rapidly. forming water-insoluble polymers) to produce polymers of extremely high molecular weight and the reaction is abruptedly halted at a point just short of water insolubility.
  • the molar ratio is from about 1%:1 to l /2:1 of diisocyanate to glycol, respectively. The molar ratio is extremely important as too much diisocyanate rapidly produces water-insoluble products and too little diisocyanate produces brittle polymers which make weak films which are unsuitable for sizing purposes.
  • the abrupt halting of the reaction may be accomplished by the addition of a stopping agent which reacts with isocyanate radicals to block further reaction with the glycol.
  • a stopping agent which reacts with isocyanate radicals to block further reaction with the glycol.
  • Such stopping agents include water, all monohydroxy alcohols including both saturated and unsaturated long chain alcohols, organic monoamino compounds, aryl monohydroxy compounds and the like.
  • waterstopped polymers are preferable to those stopped with amines and aryl hydroxy compounds.
  • Aliphatic monohydroxy alcohols are still further preferred, as polymers so stopped have been found to maintain even better weaving efiiciency over a period of time when used as a size.
  • Methanol being both inexpensive and efficient, is an excellent stopping agent for abruptly halting the polymerization reaction at the right point.
  • the minimum amount of stopping agent to be added will vary according to the excess of diisocyanate used. While a theoretical minimum may be readily calculated, it is preferred .to add at least a molar equivalent for the isocyanate used, as a safe excess. Additional quantities are ordinarily not harmful.
  • reaction should proceed as far as reasonably possible short of the point of water-insolubility to obtain polymers having the most desirable film strength.
  • products made in accordance with this invention may be made by duplicating the conditions except that reaction is halted at a time less than time X and greater than of X.
  • the polymerization time and temperature may be varied over a considerable range so long as the reaction is stopped at the critical point.
  • the reaction must be carried out at a temperature above the melting point of the polyalkylene ether glycol. However, the reaction proceeds slowly unless the temperature is elevated above about 70 C. but the temperature should not exceed 200 C. because higher temperatures tend to decompose the polyoxyalkylene chains.
  • the preferred range is from about 100 C. to 150 C.
  • the time of the reaction is a function of the temperature, the reactants, the catalyst and other factors. Suitable times have varied from 8 minutes to about an hour.
  • polyalkylene ether glycols refers to polyethers which are derived from alkylene oxides or glycols or from other heterocyclic ethers such as dioxolane, and which may be represented by the formula HO(RO) H, in which R stands for a lower alkylene radical and n is an integer greater than 1. Not all the alkylene radicals present need be the same and polyethers containing a mixture of radicals can be used, although the choice of radicals should be such that the resulting polyether is water soluble. These polyalkylene ether glycols are either viscous liquids or waxy solids.
  • the molecular weights of the polyalkylene ether glycols which are most useful in the process of this invention are at least 750 and may be as high as 20,000.
  • the preferred glycols are the polyethylene ether glycols.
  • aryl diisocyanates may be used in this invention, but monophenyl diisocyanates are preferred. Suitable compounds include 2,4 toluene diisocyanate, m-phenylene diisocyanate, 4-chloro-l,3 phenylene diisocyanate, methylene-bis-(4 phenyl isocyanate),
  • naphthalene-1,5-diisocyanate and the like.
  • Any catalyst known to be useful in the reaction of polyalkylene ether glycols with aryl diisocyanates may be used in the present invention including the tertiary organic bases of U.S. Patent No. 2,692,874 such as triethylamine, pyridine, tri-n-butylphosphine, their acid salts and the like.
  • organo-metal salts such as cobalt naphthenate and similar salts of lead, zinc, copper and manganese.
  • the organic radicals may be either aliphatic or aromatic residues.
  • substantially anhydrous polymer is used to define a polymer containing less than about 0.5% moisture. It has been found that some commercial polyalkylene ether glycols containing as much as 0.5 moisture react improperly to provide films of poor strength, making them unsuitable for textile sizes. In practice, the moisture content of the polyalkylene ether glycols will be kept as low as possible.
  • SIZING PROCEDURE Sizing yarns in accordance with this invention is a matter of utmost simplicity.
  • the novel polymers may be dissolved in water and used at any temperature between room temperature and the boil. However, excellent yarn penetration is obtained at temperatures between 120 F. and 180 F. and higher temperatures are entirely unnecessary. Conventional equipment is completely satisfactory.
  • a one-piece size is satisfactory but the invention is not limited thereto; suitable additives may be used if desired, for example, a small quantity of a silicone has been found to impart excellent qualities of lubricity thereby improving weaving efiiciency.
  • the amount of silicone used will be from about 0.01% to 1% and preferably about 0.25%. Somewhat larger quantities may be used in some instances but such uses are merely wasteful.
  • raising the addition of ammonia to raise the pH of the solution to about pH 8.59.5 also provides a definite improvement in weave room performance, apparently by reduction of any tendency of the polymers to pick up moisture.
  • the amount of size to be applied will vary somewhat accord ing to the nature of the fibrous materials, the type of yarn, the denier or count and the like but in general 2.5% to 5% polymer solids on the weight of the yarn provides a suitable size.
  • the concentration of the sizing solution may vary over a fairly wide range of from about 2% to 15% but a 4% to 8% solution of the polymer is preferred.
  • hygroscopic properties of the polymer must be minimized because weaving is normally done under very high humidity conditions.
  • the silicone rises through the polymers of aryl diisocyanate and polyalkylene ether glycol when mixtures of the two are cast into films from an aqueous medium.
  • This provides a sort of two layer effect permitting the hydrophobic properties of the silicone to be effectively utilized.
  • aqueous medium containing an alcohol stopped watersoluble polymer of the invention and a silicone with the medium having a controlled pH of from about 8.5-9.5.
  • Yarns sized in accordance with this preferred procedure have a coating of polymer topped by a coating of silicone.
  • the stability of the polymer in solution is excellent so that it may be stored in any of its liquid or solid forms and its good water solubility permits mixing at any point in the mill whereby a separate mixing operation and operator, as required for starch sizing, may be eliminated.
  • the invention is described both in the specification and claims in terms of sizing textile yarns and it will be understood that the term yarn includes both spun fiber yarns and filament yarns.
  • the invention is particularly applicable to spun Dacron ethylene glycol terephthalic acid polyester, spun mixtures of cotton and Dacron, cotton, viscose and acetate and the like.
  • the polymers of this invention may be further reacted in situ on yarn to provide the desired products.
  • formaldehyde, acetaldehyde, acrolein, other aldehydes, and/or aldehyde donors such as methylol melamines, methylol ureas, methylol ethylene ureas, copolymers of acetone and formaldehydes, methylol acetylene diureas and the like may be added to the sizing solution preferably in the presence of an acidic catalyst so that they will react with the polymer on the slasher dry cans to produce water-insoluble cross-linked films on the yarn.
  • Example 1 92 pounds of substantially anhydrous polyethylene ether glycol in a molecular weight range of 6000-7500 (Carbowax 6000) was melted in a 50 gallon reactor equipped with a reflux condenser and a stirrer. When the temperature reached 70 C., 4 pounds and 3 ounces of 2,4 toluene diisocyanate (Nacconate was added with stirring. 183 grams of a 6% solution of cobalt naphthenate was added forthwith to catalyze the reaction. At the end of the addition, the temperature had risen to 88 C. as heating was continued throughout the reaction. In about 20 minutes the reaction temperature reached C. This temperature was maintained for 15 minutes while stirring continued.
  • Example 2 To 35 grams of molten (120 C.) polyethylene ether glycol of a molecular weight range of 6000-7500, there, was added 1 gram of 2,4toluene diisocyanate and 5 drops of cobalt naphthenate solution (6%). The temperature was maintained for 5 minutes after which water was added in a quantity suflicient to make a 10% solution. The reaction proceeded as in Example 1, except that the smaller quantity required less time for reaction to the same point and reaction was stopped with water rather than methanol. The appearance of the two solution products was not distinguishable to the naked eye. The product of this example had a viscosity of 333 centipoises.
  • Example 3 warp of several thousand ends of 100% spun Dacron yarns was sized on conventional synthetic slasher equipment having a heated size-box, standard squeeze rolls and Teflon-coated dry cans.
  • the yarns were impregnated by passing them through the size box containing a water solution of the product of Example 1 diluted to 6% solids and brought to pH 9 with ammonia.
  • the size box temperature was kept at 150 F. and the squeeze rolls were set to leave 3.5% solids on the yarn. Drying was completely conventional with dry can temperatures of about 200 F.
  • the slasher operated smoothly without hard size problem, with no sticking on the cans and excellent action was noted at the split rods. It appears as though splitting might be a smooth tear for no jagged edges were noted at the split lines and the split ran back from the rods a greater distance than normal.
  • a beam of the sized yarns was placed on a loom and readily Woven into an all Dacron fabric of standard plain weave construction. Good weaving efficiency was noted immediately and shedding was minimized.
  • Complete desizing was effected by washing the Woven fabric for 30 minutes in lukewarm water, even without a surface active agent.
  • Example 4 In a suitable reaction vessel there is placed 50 parts by weight of dimethyl silicone oil (5000 centipoises), parts by weight of perchlorethylene, parts toluene, and 5 parts oleic acid. The resulting mixture agitated until solution was complete.
  • a size mixture was prepared as in Example 3 except there was dispersed in the aqueous mixture 2% by weight of the above silicone solution. The size mixture was then applied according to the procedure of Example 3 to a warp of several thousand ends of 100% spun polyethylene terephthalate (Dacron) yarns. The sized yarns appeared to have more lubricity than those from the preceding example, and this may account for the even greater weaving efliciency noted.
  • Example 5 added.
  • a conventional cotton slasher was used with the size box heated to a temperature of 130 F. Excellent running conditions were noted as in Example 3.
  • the sized warp was woven into an all cotton fabric. Weaving efiiciency was good and shedding was minimized.
  • the size film had become insoluble and could not be washed out, thus providing a high-quality loom finished cotton fabric.
