Definitions

  • a synthetic thermoplastic yarn finish having excellent antistatic properties, lubricity and stability in aqueous emulsion is provided by a mixture of an imidazolinium alkylsulfate, an alkyl ester of a fatty acid, and a water-oil emulsifier for the alkyl ester.
  • This invention relates to a finish for synthetic thermoplastic yarn.
  • Some synthetic thermoplastic yarns are made of nylon, nylon copolymers, polyesters, polyester copolymers, and the like.
  • Nylon is a long-chain synthetic polymeric amide having recurring amide groups as an integral part of the main polymer chain, and is capable of being formed into a filament in which the structural elements are oriented in the direction of the axis.
  • Nylon includes nylon-66 (polymeric hexamethylene diammoniumadipate), nylon-6 (polymeric 6-aminocaproic acid), nylon-610 '(polyhexamethylene sebacamide), nylon-4, nylon-7, nylon-11, etc., and fiberforming co-polymers thereof.
  • Polyester is a long-chain synthetic polymer composed of at least 85 percent by weight of an ester of a dihydric alcohol and terephthalic acid.
  • Another object is to provide a finish for synthetic thermoplastic yarn that will improve the dyeability of fabrics produced therefrom.
  • a finish for synthetic thermoplastic yarn comprising a lubricant, an emulsifying agent and an antistatic agent. Based on its weight, 40-70 percent of the finish is lubricant, 20-60 percent is an emulsifier or a mixture of emulsifiers, and 5-20 percent is a quaternary imidazolinium compound having the general formula:
  • R is an aliphatic radical having from 10 to 20 carbon atoms and containing at most three carbon to carbon double bands, R is a saturated aliphatic radical having from 2 to 6 carbon atoms, and R is a C H OH radical with n being an integer from 1 to 5.
  • a quite suitable lubricant for use in the instant finish is a member of the class of fatty acid esters represented by the general formula RCOOR wherein R is a saturated aliphatic radical containing 1-22 carbon atoms and R is a saturated aliphatic radical containing 1-12 carbon atoms.
  • RCOOR fatty acid esters represented by the general formula RCOOR wherein R is a saturated aliphatic radical containing 1-22 carbon atoms and R is a saturated aliphatic radical containing 1-12 carbon atoms.
  • esters are butyl stearate, butyl laurate, butyl myristate, butyl palmitate, isopropyl palmitate and neopentyl stearate.
  • Span is a random mixture of partial esters of fatty acids and hexitol anhydrides (hexitans and hexides) derived from sorbitol. The structure of Span compounds is shown below:
  • the emulsifier Tween composed of a random mixture of components, canbe obtained by adding'bxy ethylene chains to the non-esterified hydroxyls of a Span mixture.
  • Tween has the composition shown by the structural formulas 'below:
  • Propylene oxide units can also be used rather than ethylene oxide to produce a like material, however, ethylene oxide is preferred.
  • Both of the above described emulsifiers are random mixtures.
  • random mixture means a combination of components whose relative proportions are not critical. That is, the individual components can be present in the combination in any and all proportions with respect to each of the other components without changing the end result, i.e., proper emulsification, obtained by the combination of components.
  • each of the emulsifiers Span and Tween alone or in combination with one another.
  • a combination is preferred, for Span is lipophilic or oil loving and Tween is hydrophilic or water loving thereby producing a better emulsion than would one emulsifier alone.
  • any kind of emulsifier capable of performing the same function i.e., suitably emulsifying the lubricant with water, is quite as suitable as either Span or Tween or a combination thereof for use in the subject finish.
  • Electrostatically charged yarns and fabrics may not only repel one another but may also attract and hold dirt, dust, lint, and the like. Weaving and other fabric manufacturing operations are made more difficult by electrostatic charges on the yarn which cause flaring filaments. In order to overcome these difficulties, it is necessary to use an antistatic agent in the finish.
  • antistatic agents contain ionizable and/or hydrophilic groups which enable them to dissipate static charges.
  • Cationic antistatic agents are generally long-chain, surface active, non-ionic or cationic surfactants, although anionic materials have been found to be somewhat effective.
  • Cationics generally used as antistatic agents include quaternary ammonium halides, alkyl imidazoline hydroactetates, alkyl betaines, and fatty acid polyamine condensates. Cationic antistatic agents have longer lasting effectiveness than do non-ionic agents because they are more difficult to remove during laundering and dry cleaning.
  • cationic antistatic agents possess certain desirable properties, but it was expected that a cationic antistatic agent would precipitate when used in conjunction with the hereinabove described lubricants (fatty acid esters) and emulsifying agents (Span and Tween). Nevertheless, when an attempt was made to use a quaternary imidazolinium'compound' (a cationic antistatic agent), having a structure such as that shown hereinbefore, in conjunction with a fatty acid ester and emulsifiers Span and Tween, surprisingly, no precipitation occurred and an excellent, quite stable emulsion was obtained when this finish was homogenized with water.
  • quaternary imidazolinium compounds suitable for use in the present finish are l-(2-hydroxyethyl)- l-ethyl-2-oleyl-imidazolinium ethyl sulfate, 1-(2-hydroxyethyl)-l;ethyl 2 stearyl-imidazolinium ethyl sulfate, 1-(2- hydroxyethyl) -l-ethyl-2-linoleylimidazolinium ethyl 'sulfate, 1.
  • An aqueous finish composition is prepared by homogenizing finish, composed of lubricant, emulsifying agent or mixture of agents, and an antistatic agent (a quaternary imidazolinium compound), with water.
  • the generally desirable ranges for each of the finish components, expressed in weight percent based on total finish weight, are shown in the table next below.
  • the emulsifying agent is composed of two components: 1) material designated by the trademark Span and (2) material designated by the trademark Tween. These two materials can be present in the finish in various proportions. However, a desirable percent range for each material based on total emulsifier weight is set forth in the table next below.
  • the yarn passes in contact with a roller or wick partially immersed in aqueous finish composition.
  • Other finish application methods consist of spraying, brushing, or immersing the yarn in an aqueous finish composition bath.
  • the amount of finish and water in the aqueous finish composition may vary. Concentration can depend, among other things, upon the particular impregnation method employed and on the kind of filaments treated. Aqueous finish compositions having from about 3 to about 48 percent finish therein based on the total weight in the aqueous finish composition are quite suitable.
  • Example I A particular finish was prepared in the following manner. A mixture of materials shown in the following table in the indicated proportions based on the total weight of all components was prepared.
  • This aqueous finish composition was then applied to a bundle of meltspun 34 nylon-66 filaments having a total denier of 185, at a point between the spinneret and the bobbin used to take up the filaments.
  • the yarn was thus coated with 1 percent finish based on yarn weight.
  • These filaments were then drawn on a conventional draw-winding machine employing two sets of rolls; a draw-pin between said rolls, around which the yarn was snubbed; and a take-up assembly in which the yarn was collected on a bobbin. Between the two sets of rolls, the filaments were drawn 2.63 times.
  • the emulsion appeared to be quite stable, showing no signs of separation into an oil and aqueous phase at any time during its use.
  • the yarn with the instant finish applied thereto was shipped to a weaving mill. There it was used as filling yarn in the weaving process. Filling yarn is wound on a small spool or quill which is placed on the shuttle of a loom.
  • Fabric woven from the above described yarn proved to be extremely pleasing in appearance with significant reduction in dye streaks, bands, and quill junctions.
  • the yarn exhibited very good lubricity, excellent bundle cohesion and good antistatic properties during the weaving operation.
  • Example II A yarn made from nylon-66 consisting of a bundle of 34 filaments having a total denier of 70 was treated with the finish described in Example I. It was compared with a competitive yarn having the same denier and number of filaments. Fabric samples were then woven using in one sample, yarn treated with the finish of the invention and, in a second sample the competitive yarn, as fill yarn. Fabric having fill yarn treated with the inventive finish had fewer streaks, bands, and quill junctions than did fabric wherein the fill yarn was a comparable, competitive yarn treated with another kind of finish.
  • the improved lubricity provided by the subject finish is indicated by the fact that the competitive yarn showed 1820 grams tension on the yarn during quilling while yarn treated with the inventive finish measured only 14-16 grams tension under identical quilling conditions.
  • Yarn treated with the inventive finish shows marked advantages. Lubricity is significantly increased, generation of static electricity is depressed, and bundle cohesion is notably increased.
  • a finish consisting essentially of to 70 weight percent of a fatty acid ester having the formula RCOOR wherein R is an alkyl radical containing 1 to 22 carbon atoms and R is an alkyl radical containing 1 to 12 carbon atoms; 5 to 20 weight percent of a quaternary imidazolinium compound having the formula N-CH 2 Ri-G RzOSOg" N-CHz R2 R3 wherein R is selected from the group consisting of oleyl, linoleyl and an alkyl radical containing 10 to 20 carbon atoms, R is an alkyl radical containing 2 to 6- carbon atoms and R is a C H OH radical with n being an integer from 1 to 5; and 20 to 60 weight percent of at least one emulsifier selected from the group consisting of compounds having the formulae CH CH-CHzOOCR CH-OH I OH ITO-CH 10H;
