Definitions

  • This invention relates to a monofilament of low carboxyl content for use in fabricating a paper machine dryer fabric having improved resistance to hydrolytic degradation and abrasion.
  • the invention also relates to a method of making this filament and to a composition therefor.
  • Polyester monofilaments when woven into fabrics, have many applications in industrial filtration processes and as belts for conveying certain industrial product ' s. Such fabrics are used extensively in the paper industry to filter the wood pulp slurry and convey the formed paper to dryer sections of the paper-making process. The dryer section also contains conveying belts made out of industrial fabrics.
  • It is another object of the invention to provide a composition comprising: a) a polyester; b) a polyester stabilizer; and c) a thermoplastic material.
  • FIGURE 1 is a graph of the % of residual tensile strength vs. time showing a comparison in resistance to hydrolytic degradation between a commercial monofilament and the monofilament according to the invention.
  • the polyester comprises polyethylene terephthalate.
  • the thermoplastic material is selected from the group consisting of polyurethanes and polyetherester block copolymers.
  • the polyester stabilizer is selected from the group consisting of glycidyl ethers, carbodiimides, ketenimines, hydroxyl containing compounds, aziridines and isocyanates.
  • the preferred thermoplastic material consists of poly ⁇ butylene terephthalate-co-(multibutyleneoxy)tere- phthalate ⁇ . This is a Dupont material known as HYTREL.
  • thermoplastic material to be added depends on the balance between the degree of abra- sion resistance required and the deterioration in the physical properties of the monofilament due to addition of the thermoplastic material. Amounts ranging from 1 percent to 30 percent of the compatible polymer may be used in the blend with 5 to 15 percent being the optimum for most applications.
  • the preferred polyester stabilizer consists of a polycarbodiimide known under the trademark STABAXOL.
  • polyester stabilizer Preferably, there is added about 0.1 to 5 percent by weight of said polyester stabilizer, more preferably about 1 to 2 percent by weight.
  • the abrasion resistance can be improved by blending the polyester with optimum amounts of a compatible polymer which has superior abrasion resistance.
  • compatible polymers with good abrasion resistance are polyurethanes produced by the reaction of methylene diphenyl isocyanate or tolylene diisocyanate with polyethylene adipate or phthalate or polyalkylene oxides.
  • Elastomeric polyesters such as polyether-ester block copolymers are also compatible with good abrasion resistance.
  • An example of elastomeric polyester is the commercial product marketed under the trademark of HYTREL which is poly ⁇ butylene tere- phthalate-co-(multibutyleneoxy)terephthalate ⁇ .
  • the polymers mentioned above have melt points considerably lower than those of the polyesters into which they are incorporated.
  • the hydrolytic stability of the polyester is improved by the addition of organic compounds such as carbodiimides which act as acid scavengers.
  • organic compounds such as carbodiimides which act as acid scavengers.
  • the carboxyl end-groups in the polyester molecules catalyze chain- scission at the ester linkages, thereby degrading the physical properties of the product.
  • organic compounds with groups capable of reacting with the COOH end-groups are known to the prior art and may be used as stabilizers for polyesters. Examples of such groups known to the prior art are gly- cidyl ether, carbodiimide, ketenimine, hydroxyl, aziri- dine and isocyanate.
  • the stabilizer is normally incor ⁇ porated in the molten resin immediately after polymeri ⁇ zation or in the extruder during the fabrication process .
  • the stabilizer is good stability to high temperatures, a melting point below normal processing temperatures and lower diffusivity through the polymer.
  • Polycarbodiimide such as those available commercially under the trademark of STABAXOL meet all those requirements and is used extensively with polyurethane and polyester products.
  • the polycarbodiimide is not readily soluble in molten polyesters, and since it has a low viscosity, it cannot be processed in a conventional single screw extruder without creating erratic flow and conveying in the feed section of the screw. Expensive modifications of the extruder would be necessary in order to overcome the feed problems.
  • An alternative to modifying the extruder is to compound the stabilizer in an appropriate carrier prior to incorporating into the polyester.
  • the carrier for a compounded concentrate can be any thermoplastic material.
  • a material having a low melt point to prevent thermal degradation of the stabilizer during compounding. It is also preferable to use a carrier that is compatible with the polyester.
  • Poly- urethanes and elastomeric polyesters are the most suit ⁇ able carriers and this invention relates to their use in producing polyester monofilaments with low carboxyl con ⁇ tent.
  • the method of making a monofilament of low carboxly content for use in fabricating a paper machine dryer fabric having improved resistance to hydrolytic degrada ⁇ tion and abrasion comprises: a) compounding a polyester stabilizer in a thermo ⁇ plastic material; b) incorporating the compounded material obtained in step a) with a polyester; and c) extruding the mixture obtained in step b) in a screw extruder so as to obtain a monofilament.
  • resistance to hydrolytic degradation means resistance to chemical degradation from the reaction of steam with the polyester. The chemical degradation results in a loss in strength of the monofilament fiber.
  • Monofilaments to be tested were wrapped around a tared polyethylene rod and reweighed to obtain the weight of monofilament used in the test.
  • the rod with the mono- filament was spun in a sand slurry for 40 minutes .
  • the sa ple was then removed, dried and reweighed to determine the weight loss.
