Definitions

  • filament yarns of the present invention have a wicking characteristic of about 6 mm or less, a contact angle of greater than or equal to about 65° but less than about 90°, and have a static voltage range of +/- 400 volts (a voltage between -400 to +400).
  • Such filament yarns are made using an aqueous dispersion of a specific fluorocarbon surfactant, or a mixture of a few specific surfactants, that is used to impart water and oil repellency to synthetic fibers.
  • Known fluorocarbon surfactants that impart water and oil repellency to synthetic fibers are not capable of achieving the wicking angle, contact angle and static voltage mentioned previously.
  • fluorochemical emulsions and specifically fluorocarbon surfactant emulsions to impart oil and water resistance to synthetic fibers is well known. These treatments can be applied in the form of a spin finish to impart moisture resistance in fabric made from the fiber or continuous filament. Its use as a spin finish for carpet fibers, for example, is to impart water and oil repellency to the synthetic fibers.
  • the following prior art illustrate these technologies.
  • U. S. Patent 6,536,804 to Dunsmore et al. relates to carpet fibers in which a spin finish is applied to the synthetic staple fibers (not continuous filament yarn) for creating a surface on the carpet that is water and oil repellent.
  • fluorochemicals were components of the spin finish.
  • U. S. Patent Application Publication Number US 2003/0175514 to Hancock et al. discloses a low wicking type material that has use in fabrics, which are water repellent. Specific polymers disclosed are nylons, polyesters and polyolefins. This reference also discloses that a filament has a contact angle greater than or equal to 90° as measured by the method disclosed in the Journal of Colloid and Interface Science, 177, 579-588 (1996). This reference also discloses a filament having a coating thereon and wherein the contact angle of the coated filament is greater than or equal to 90°.
  • the coating (described as the "second longitudinally-extending component of the filament”) can be virtually any halogenated polymer as disclosed in Paragraph 29.
  • the polarity of the static voltage depends on the relative position of the yam and the rubbing surface on the triboelectric series.
  • continuous filament yams having a static operating range of +/- 400 volts permits the continuous filament yams to be processed into a fabric in virtually any ambient air conditions, without the need of static eliminators in the fiber forming and fabric forming equipment, and because the continuous filament is drier, the processing equipment can be ran at faster output.
  • the present invention teaches a filament ya that has low wicking, i.e., less than or equal to about 6 mm; has a contact angle of greater than or equal to about 65° but less than about 90° according to the straw method; and a static voltage of +/- 400 volts (between -400 to +400 volts).
  • the preferred ya is continuous
  • the yams of the present invention have a contact angle greater than or equal to about 65°, while yams of the prior art have contact angles less than about 65° or greater than about 90°.
  • Those known low wicking continuous filament yams commercially available at the present time will not have wicking less than or equal to about 6 mm, a static voltage of +/- 400 volts, and a contact angle greater than or equal to about 65°.
  • the contact angle test and evaluation are described by Augustine Scientific at Newbury, OH. Like all contact angle tests, the higher the degree, the more non wetting the continuous filament is.
  • the sign of the static voltage will depend on the relative position of the type of ya and the rubbing surface on the triboelectric series. Generally polyester and nylon will be positively charged.
  • Thermoplastic polymers useful for making synthetic fibers of this invention include fiber-forming polyesters, poly(alpha)olefins, polyamides and acrylics.
  • Preferred thermoplastic polymers are polyesters are produced from the reaction of a diacid or diester component comprising at about 65 mole % terephthalic acid or d - C 4 dialkylterephthalate, preferable at least 70 mole %, and a diol component comprising at least about 65 mole % ethylene glycol, preferably at least 70 mole %, more preferably at least 75 mole %, even more preferably at least 95 mole %. It is also preferable that the diacid component is terephthalic acid and the diol component is ethylene glycol. The mole percentage for all the diacid component totals 100 mole %, and the mole percentage of all the diol component totals 100 mole %.
  • suitable diol components of the described polyesters may be selected from 1 , 4-cyclohexanedimethanol, 1, 2-propanediol, 1 , 3-propanediol, 1 , 4- butanediol, 2, 2-dimethyl-l, 3-propanediol, 1, 6-hexanediol, 1, 2-cyclohexanediol, 1 , 4- cyclohexanediol, 1 , 2-cyclohexanedimethanol and diols containing one or more oxygen atoms in the chain, e.g., diethylene glycol, triethylene glycol, dipropylene glycol, tripropylene glycol or mixtures of these, and the like.
  • these diols contain 2 to 18, preferable 2 to 8 carbon atoms.
  • Cycloaliphatic diols can be employed in their cis or trans configuration or as mixtures of both forms.
  • Preferred modifying diol components are 1 , 4-cyclohexanedimethanol or diethylene glycol, or a mixture of these.
  • the suitable acid components (aliphatic, alicyclic, or aromatic dicarboxylic acids) of the linear polyester may be selected, for example, from isophthalic acid, 1, 4-cyclohexanedicarboxylic acid, 1, 3-cyclohexanedicarboxylic acid, succinic acid, glutaric acid, adipic acid, sebacic acid, 1 , 12-dodecanedioic acid, 2, 6- napthalenedicarboxylic acid, bibenzoic acid, or mixtures of these and the like.
  • a functional acid derivative thereof such as the dimethyl, diethyl, or dipropyl ester of the dicarboxylic acid.
  • the anhydrides or acid halides of these acids may also be employed where practical.
  • thermoplastic polymers are poly(alpha)olefins, including the normally solid, homo-, co- and terpolymers of aliphatic mono- 1 -olefins (alpha olefins) as they are generally recognized in the art.
  • the monomers employed in making such poly(alpha)olefins contain 2 to 10 carbon atoms per molecule, although higher molecular weight monomers sometimes are used as comonomers.
  • Blends of the polymers and copolymers prepared mechanically or in situ may also be used.
  • Examples of monomers that can be employed in the invention include ethylene, propylene, butene- 1 , pentene-1 , 4-methyl-pentene-l , hexene-1 , and octene-1 , alone, or in admixture, or in sequential polymerization systems.
  • Examples of preferred thermoplastic poly(alpha)olefin polymers include polyethylene, polypropylene, propylene/ethylene copolymers, polybutylene and blends thereof. Polypropylene is particularly preferred for use in the invention.
  • Typical polyamides suitable for this invention are nylon 6 and nylon 66.
  • Processes for preparing the polymers useful in this invention are well known, and the invention is not limited to a polymer made with a particular catalyst or process.
  • the process of melt spinning the multifilament yam is well known in the art.
  • the molten polymer is fed under high pressure to the heated housing which accommodates the spinning.
  • the molten polymer is forced through a number of spinning orifices provided in a spinneret.
  • the filaments emerge from the spinneret as a bundle.
  • the filament bundle may pass through a delay zone (heated or unheated) prior to a quench zone, in which the bundle is cooled with air of room temperature, which is blown onto the filaments transverse to the direction of movement of the bundle.
  • the filament bundle is subsequently brought into contact with the finish metering unit in which a suitable lubricant is applied to the filaments of the bundle in the usual way.
  • the multifilament bundle arrives at the first of a set of advancing rolls for imparting the correct speed to the yam bundle.
  • the circumferential speed of the feed roll is determinative of the speed at which the filaments are spun and is therefore referred to as the spinning speed.
  • the spun multifilament yam After the spun multifilament yam has left the rolls, it is wound into a package. The speed at which the yam is wound will be approximately equal to the spinning speed. After the yam has been taken up, it is drawn on a separate machine to the desired ratio. In principle, however, drawing also may be carried out on the spinning machine in a continuous spin-drawing process. In the event of the spin- drawing process known per se being applied a drawing device consisting of one or more driven rolls is to be provided between the first driven roll and the winding bobbin.
  • plastic additives can also be added.
  • plastic additives may be anti-static agents, biocides, coloring agents (dyes and pigments), coupling agents, flame retardants, heat stabilizers, light stabilizers, lubricants, plasticizers and mixtures of a plurality of these.
  • Fluorocarbon based surfactants are amphiphilic materials containing an oleophobic and hydrophobic perfluorinated tail and a hydrophilic head. They are effective to reducing the surface tension of surfaces, since the oleophobic tail bonds to the polymer surface and the molecule orients perpendicular to the surface.
  • a key variable in different fluorocarbon based surfactants is the number of carbon atoms in the perfluorinated tail of the compound. It is generally thought that longer chain (C 8 ) fluorochemical tails give lower surface reduction potentials than shorted chains. In the case of their use as spin finishes for fibers it is important that the fluorochemical gives a high surface coverage so that there are no bare areas along which the water can wick. Although not bound by theory, it is believed that the shorter chains take longer to organize and thus flow better on the polymeric fiber surface.
  • the aqueous dispersion fluorocarbon chemicals used in the present invention are known by their trade names of Afilan 5248A and Afilan 5284B produced by Clariant. Additionally, trade names Lurol FC-L575 and FC-L790 produced from Goulston are likewise satisfactory. The aqueous dispersion fluorocarbon chemicals mentioned above are suitable for the present invention and provide these properties.
  • aqueous dispersion fluorocarbon chemicals Mitsubishi Chemical Company (Repearl F89, a perfluoroalkyl polyacrylate copolymer emulsion), 3M (F359, a perfluoroctane based surfactant) have been tested but have been found to be lacking and do not provide a wicking of less than or equal to about 6 mm, a contact angle (as determined by the straw method) of about 65° or more, and a static voltage of less than or equal to +/- 400 volts. Since these are proprietary spin finishes, the detailed differences are not known. It was surprising that there was a difference between the various fluorocarbon based finishes.
  • the aqueous dispersion fluorocarbon chemicals are applied to the fibers as a spin finish, for example.
  • the aqueous dispersions are prepared to give about 15 % by weight solids with the remainder being water.
  • spin finishes are suitable for the present invention.
  • Wicking is determined by the distance that a dye solution wicks up the vertically suspended yam.
  • a 0.5 wt-% aqueous dye solution of Palanil Cerise NSL 200 (BASF Corporation) is prepared.
  • a paper clip (0.5 g) is tie to one end of the yam and suspended into a 50 ml beaker.
  • the dye solution is added to the beaker so that it just covers the knot. After 45 minutes, the yam is lifted out of the beaker and allowed to dry. The amount of wicking above the knot as indicated by the dye line is measured.
  • the contact angle is determined by the straw method, as explained by Augustine
  • the contact angle is the quantitative measure of wet-ability for a solid surface being wetted with a liquid, which ranges from 0 (perfect wetting) tol 80° (complete non-wetting).
  • the contact angle using the straw method is measured by using several fibers each having a length of about 7.5 cm, which are laid together. A thin flexible copper wire is looped around the fibers and both ends of the wire are fed through a small piece of tubing (the

Abstract

La présente invention concerne un fil continu qui présente un faible effet de mèche, c'est-à-dire inférieur ou égal à environ 6 mm. Ce fil présente un angle de contact supérieur ou égal à environ 65°, mais inférieur à environ 90°, selon la méthode de la paille, ainsi qu'une tension statique de +/- 400 volts (entre 400 volts et +400 volts). De tels fils sont généralement utilisés pour tisser des enseignes, des bannières, des auvents, des tentes et autres produits où il est important d'utiliser un fil résistant à l'humidité. Les fils selon cette invention peuvent être utilisés pour produire des toiles qui présentent les mêmes caractéristiques que le fil, c'est-à-dire un faible effet de mèche, ainsi qu'un comportement hydrophobe et oléophobe.
