Definitions
- This invention relates to polyethylene naphthalate (PEN) multifilament yarn and other yarns made from similarly rigid monomer combinations with extremely high modulus, good tenacity, and low shrinkage particularly useful for the textile reinforcement of tires.
- the PEN yarn of this invention provides enhanced modulus and dimensional stability when compared to conventionally processed PEN yarns.
- a process for production of the multi-filament PEN yarn is an aspect of this invention.
- PET polyethylene terephthalate
- the resulting yarn exhibits surprisingly high modulus and tenacity together with low shrinkage when compared to prior art yarns.
- the invention also provides a drawn semicrystalline polyester multifilament yarn having Tg greater than 100°C and a melting point elevation of at least 9°C, which is obtained by drawing a polyester yarn having an undrawn birefringence of at least 0.030.
- Fig. 1 represents a comparison of modulus at a tenacity of 6.2 g/d (54.7 mN/dtex) for the PEN yarns of Examples 1 and 2.
- the polyester multifilament yarn of the present invention provides high modulus, high dimensional stability and good tenacity, characteristics which are extremely desirable when this material is incorporated as fibrous reinforcement into rubber composites such as tires.
- PEN multifilament yarns or other yarns of polyester polymers made from similarly rigid monomer combinations can be used advantageously to reinforce two parts of a radial passenger tire, the carcass and the belt.
- passenger tire carcasses are reinforced primarily by polyethylene terephthalate.
- Two tire characteristics which are controlled by the carcass cord property of dimensional stability (modulus at a given shrinkage) are sidewall indentations and tire handling.
- PEN multifilament yarns and other polyester yarns of this invention can also be used to reinforce the belts of radial passenger tires and the carcasses of radial truck tires.
- steel is used for these applications since PET prossesses insufficient strength and modulus for a given cord diameter.
- the high modulus of PEN relative to PET, and the additional modulus advantages of the PEN of this invention will make PEN an ideal material to be used as a steel substitute.
- the polyethylene naphthalate yarn of the invention contains at least 90 mol percent polyethylene naphthalate.
- the polyester is substantially all polyethylene naphthalate.
- the polyester may incorporate as copolymer units minor amounts of units derived from one or more ester-forming ingredients other than ethylene glycol and 2,6 naphthylene dicarboxylic acid or their derivatives.
- ester forming ingredients which may be copolymerized with the polyethylene naphthalate units include glycols such as 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol, etc., and dicarboxylic acids such as terephthalic acid, isophthalic acid, hexahydroterephthalic acid, stilbene dicarboxylic acid, bibenzoic acid, adipic acid, sebacic acid, azelaic acid, etc.
- glycols such as 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol, etc.
- dicarboxylic acids such as terephthalic acid, isophthalic acid, hexahydroterephthalic acid, stilbene dicarboxylic acid, bibenzoic acid, adipic acid, sebacic acid, azelaic acid, etc.
- polyester yarns of the invention can be prepared to contain polyester polymer made from suitable combinations of rigid and flexible monomers providing the resulting polymer is melt-spinnable, is semi-crystalline, and has a Tg greater than 100°.
- rigid monomers include dicarboxylic acids such as 2,6-naphthalene dicarboxylic acid, 2,7-naphthalene dicarboxylic acid, diphenyl dicarboxylic acid, stilbene dicarboxylic acid and terephthalic acid; dihydroxy compounds such as hydroquinone, biphenol, p-xylene glycol, 1,4 cyclohexanedimethanol, neopentylene glycol; and hydroxycarboxylic acid such as P-hydroxybenzoic acid and 7-hydroxy- ⁇ -naphthoic acid.
- Examples of flexible monomers include dicarboxylic acids such as oxalic acid, succinic acid, adipic acid, sebacic acid, and dihydroxy compounds such as ethylene glycol, 1,3 propanediol, 1,4 butanediol, 1,6 hexanediol. It is important that the thermal stability of the polymer above its melting point be sufficient to allow melt processing without excessive degradation.
- the multi-filament yarn of the present invention commonly possesses a denier per filament of about 1 to 20 (e.g. about 3 to 10), and commonly consists of about 6 to 600 continuous filaments (e.g. about 20 to 400 continuous filaments).
- the denier per filament and the number of continuous filaments present in the yarn may be varied widely as will be apparent to those skilled in the art.
- the fibers are particularly suited for use in environments where elevated temperatures (e.g. 100°C) are encountered. Not only does the filamentary material provide enhanced modulus but it undergoes a very low degree of shrinkage for a high modulus fibrous thermoplastic.
- L T ((L-5) 4 /T 5.16 ) 1000 L-5 or LASE-5 is a measure of modulus defined as load in g/d at 5% elongation.
- the materials of this invention have L T at least 25. If L-5 is not measurable because of yarn elongations less than 5% the yarns will be pre-relaxed at elevated temperatures before testing to increase elongation beyond 5%.
- Shrinkage values were determined in accordance with ASTM D885 after one minute at 177°C employing a constraining force of 0.05 g/denier (0.44 mN/dtex).
- the melt-spinnable polyester is supplied to an extrusion spinnerette at a temperature above its melting point and below the temperature at which the polymer degrades substantially.
- the residence time at this stage is kept to a minimum and the temperature should not rise above 350°C, preferably 320°C.
- the extruded filaments then traverse a conventional yarn solidification zone where quench air impinges on the spun yarn thereby freezing in desirable internal structural features and preventing the filaments from fusing to one another.
- the solidification zone preferably comprises (a) a retarded cooling zone comprising a gaseous atmosphere heated at a temperature to at least 150°C, preferably 150 to 500°C, and (b) a cooling zone adjacent to said retarded cooling zone wherein said yarn is rapidly cooled and solidified in a blown air atmosphere.
- the key to the current process is to adjust processing conditions to achieve a highly oriented undrawn yarn of birefringence at least 0.03 and an elevated melting point of 1-25°C, preferably 3-23°C.
- PEN a melting point of 265 to 290°C, preferably 268 to 288°C must be achieved.
- One skilled in the art can achieve this by adjusting the following conditions: length and temperature of the retarded cooling zone adjacent to the spinnerette, diameter of the spinnerette holes, method of blowing the quench, quench air velocity, and drawdown in the solidification zone.
- the speed of withdrawal of the yarn from the solidification zone is an important parameter affecting the stress on the spun fiber, and should be adjusted to yield the desired characteristics.
- the spun yarn is then drawn by conventional means in either a continuous or non-continuous process to yield a drawn yarn with Tg greater than 100°C and a melting point elevation at least 9°C, preferably 9 to 15°C.
- tenacity at least 6.5 g/d (57.4 mN/dtex), preferably at least 7.5 g/d (66.2 mN/dtex); dimensional stability (EASL + shrinkage) of less than 5%; and shrinkage of 4% or less.
- a PEN undrawn yarn was produced by extruding 32 filaments through a spinnerette with orifices of length 0.042 inches (0.107cm) and of width 0.021 inches (0.053 cm) at a thruput of 23.2 cc/min.
- the filaments were solidified in an air quenching column and taken up at winder speeds of 305 m/min.
- PEN yarns were produced by extruding seven filaments through a spinnerette with orifices of length 0.036 inches (0.091 cm) and width of 0.016 inches (0.041 cm) at a thruput of 9.6 cm 3 /min.
- the filaments were solidified in an air quenching column and taken up at winder speeds ranging from 770-5000 m/min. These yarns were drawn in two stages using a heating plate in draw zone two.
- the undrawn yarn properties, drawn yarn properties, and drawing conditions are summarized in Table II.
- Example II The undrawn yarns of Example II spun at 770 m/min and 4000 m/min were drawn to their ultimate limit.
- the 770 m/min sample was drawn in one stage using an oven in the draw zone and the 4000 m/min sample was drawn in two stages using a heated plate in the second draw zone.
- PEN yarns were produced by extruding seven filaments through a spinnerette with orifices of length 0.069 inches and width 0.030 inches at a thruput of 9.6 cc/min. The filaments were solidified in an air quenching column and taken up at winder speeds ranging from 410 m/min to 2500 m/min. The properties of these yarns are summarized in Table IV.
