Definitions
- the present invention relates to a high speed process for producing polyester filaments. More particularly, the present invention relates to a high speed process by which polyester filaments having a high quality can be produced with a high process stability at a high speed of 3000 m/minute or more.
- the increase in the filament-forming speed causes various problems such as friction between the moving filament yarns and various yarn guiding means (rollers and guides), friction between filaments in a moving filament yarn bundle being increased, breakage of individual filaments and breakage of filament yarns due to the breakage of the individual filaments being promoted, the resultant filament yarns exhibiting a lowered quality, and the production efficiency being rather reduced.
- JP-A-2-242,977 proposes the use of an oiling agent comprising:
- JP-A-63-112,769 discloses a specific oiling agent for polyester staple fibers, comprising 60 to 95% by weight of potassium alkyl phosphoric acid ester salt with a C 8-18 straight or branched alkyl group, 2 to 25% by weight of a silicone having a viscosity of 1,000 cps or more at 25°C and the balance consisting of mainly a non-ionic surfactant.
- the oiling agent contributes according to this reference to enhance the carding processability of the polyester staple fibers.
- JP-A-3-249,280 discloses a wear resistance-enhancing agent for fiber articles, for example, ropes, cords, belts, and woven fabrics of synthetic fibers, glass fibers or carbon fibers.
- This wear resistance-enhancing agent comprises a polyurethane, a polyethyleneoxide, a fluorine-containing resin and an ehtyleneurea compound.
- An object of the present invention is to provide a high speed process for producing polyester filaments in which breakage of individual filaments and filament yarns during a filament-forming procedure is slight and a wound filament yarn package with a good appearance can be stably formed.
- the inventors of the present invention made an effort to attain the above-mentioned object and as a result, discovered that in the high speed process for producing polyester filaments, application of an oiling treatment emulsion comprising a specific oiling agent composition is very important.
- the present invention was completed on the basis of this discovery.
- the high speed process of the present invention for producing polyester filaments comprises melt-spinning polyester filaments at a taking-up speed of 3000 m/minute or more, applying an aqueous emulsion of an oiling agent comprising 50% by weight or more of a monobasic acid ester with an average molecular weight of 300 to 500, and further containing (a) 1 to 15% by weight of a polyoxyalkylene glycol copolymer with an average molecular weight of 1000 or more, and (b) 0.1 to 3% by weight of an organic silane compound and/or a fluoroalkyl group-containing compound, is applied to the polyester filaments.
- the present invention is mainly directed to a production of filaments of a polyester having, as main recurring units, alkylene terephthalate units, for example, polyethylene terephthalate, and applied to polyester filaments which have been melt-spun at a taking-up speed of 3000 m/minute, preferably 3500 to 4000 m/minutes, and then being drawn.
- alkylene terephthalate units for example, polyethylene terephthalate
- the specific oiling agent usable for the present invention can exhibit the specific effect thereof only when the fiber-forming procedure is carried out at a taking-up speed of 3000 m/min or more.
- the oiling agent be diluted with water to provide an aqueous emulsion thereof and the aqueous oiling agent emulsion must be applied to the polyester filaments melt-spun at high speed, to smoothly impart the oiling agent to the polyester filaments moving at high speed.
- a conventional oiling agent containing no water namely so-called a straight oiling agent, has a high viscosity and exhibits a poor wetting performance for moving filaments. Therefore, fluffs are often generated in the resultant polyester filaments, or an excessively high load is applied to the moving filaments when oiled, and thus the individual filaments are often broken.
- the monobasic acid ester usable as a principal component of the oiling agent is necessarily contained in a content of 50% by weight or more, preferably 50 to 75% by weight, based on the total effective content weight of the oiling agent, in the oiling agent. If the content is less than 50% by weight, the resultant oiling agent cannot impart the lubricating performance necessary for the melt-spinning procedure at a high speed of 3000 m/min or more, to the filaments, and thus the fluff-formation and individual filament breakage are undesirably increased.
- the monobasic acid ester usable for the present invention is a monoester compound of a monovalent aliphatic carboxylic acid with a monovalent aliphatic alcohol, and has an average molecular weight of 300 to 500, preferably 350 to 450.
- This type of monobasic acid ester is preferably selected from the group consisting of octyl palmitate, octyl stearate, lauryl laurate, 2-ethylhexyl stearate, isotridecyl palmitate and isostearyl caprylate.
- the polyoxyakylene glycol copolymer usable as a further indispensable component (a) is employed to effectively enhance the strength of oil membranes formed on the peripheral surfaces of the oiled polyester filaments and to impart an enhanced abrasion resistance and anti-friction property to the filaments.
- a polyoxyakylene glycol copolymer
- the inventors of the present invention studied about how to solve the above-mentioned problems. As a result, it was found that the stability in the filament package form depends on the filament-to-filament static friction value under a relatively low load, and the value of frictional stress applied to the polyester filaments during the high speed filament-forming procedure is variable depending on the value of the filament-to-filament static friction at a high temperature under a high load. Accordingly, the inventors of the present invention studied the components of the oiling agent which exhibit a high effect in reduction of the later static friction and a low effect in reduction of the former static friction. As a result, it was found that the addition of a specific amount of the polyoxyalkylene glycol copolymer having a specific molecular weight is effective.
- the indispensable component (a) of the oiling agent usable for the present invention is a polyoxyalkylene glycol copolymer with an average molecular weight of 1000 or more, and must be contained in a content of 1 to 15% by weight based on the total effective component weight in the oiling agent.
- the content is less than 1% by weight, the effect on enhancement of the oiling agent membrane strength becomes unsatisfactory.
- the resultant oiling agent exhibits an increased viscosity
- the moving filament yarns exhibit an increased dynamic frictional coefficient due to the increased viscosity so as to promote the formation of fluffs on the yarns
- the static frictional coefficient of the moving filament yarns is reduced so that the resultant yarn package exhibits a bad winding appearance and stability.
- the resultant oiling agent causes a size layer formed on the oiled filament yarns in an after-treatment to be softened so as to reduce the sizing effect of the size layer, or to be removed during a weaving procedure so as to reduce the efficiency of the weaving procedure.
- the average molecular weight of the component (a) is less than 1000, it becomes impossible to attain the object of the present invention, because the resultant oiling agent exhibits an unsatisfactory cohesive force and thus the enhancing effect in the resultant oiling agent membrane strength becomes insufficient.
- the polyoxyalkylene glycol copolymers usable for the present invention is preferably selected from ethylene oxide/propylene oxide copolymers having side chains, for example, alkyl groups, and ethylene oxide/tetrahydrofuran copolymers having no side chains (copolymers consisting of oxyethylene units and oxy tetramethylene units).
- the terminal hydroxyl groups of the above-mentioned copolymers may be blocked with alkyl, aryl or acyl groups or not blocked.
- the copolymers when the ethylene oxide/propylene oxide copolymers are employed, it is preferable that the copolymers having an average molecular weight of 9000 or more, more preferably having a polymerization ratio (EO/PO weight ratio) of from 20/80 to 80/20 and a molecular weight of 9000 to 30,000, be employed in an amount of 4 to 15% by weight.
- EO/PO weight ratio polymerization ratio
- the copolymers having a copolymerization weight ratio of these comonomers to each other of from 20/80 to 80/20 and an average molecular weight of 1000 to 7000 be employed in an amount of 1 to 10% by weight, more preferably 1 to 5% by weight.
- the ethylene oxide/tetrahydrofuran copolymers having no side chain are used, they exhibit an excellent improving effect on the oiling agent membrane strength, and thus the restriction effect on the fluff formation and the filament or yarn breakage of the polyester filament yarns is advantageously very high.
- the upper limit in the average molecular weight of the polyoxyalkylene glycol copolymers is not specifically established. However, if this is too high, sometimes, the resultant oiling agent exhibits an excessively high viscosity and thus the resultant high speed moving filament yarns exhibit an excessively enhanced dynamic friction, and the resultant oiling agent emulsion exhibits a reduced stability and a scum is generated and deposited in the emulsion. Therefore, it is preferable that the average molecular weight of the polyoxyalkylene glycol copolymers to be employed is appropriately selected in consideration of the type of the copolymers.
- Another indispensable component (b) usable for the present invention consisting of at least one member selected from organic siloxane compounds and fluoroalkyl group-containing compounds is contained in an amount of 0.1 to 3% by weight preferably 0.5 to 2% by weight, based on the total weight of the effective components in the oiling agent.
- the addition of the component (b) causes the uniform adhesion of the oiling agent to be significantly enhanced, the contact stress generated when the filament yarns come into contact with the emulsion is reduced, and thus the resultant oiling agent is effectively employed for a high speed filament-forming procedure at a speed of 3000 m/min or more.
- the amount of the component (b) is less than 0.1% by weight, the above-mentioned effect sometimes cannot be obtained, and when the amount of the component (b) is more than 3% by weight, sometimes, the resultant oiling agent exhibits a reduced stability and an uneven dyeing phenomenon occurs on the oiled filament yarns.
- the organic siloxane compounds causing the surface tension of the resultant oiling agent emulsion to be reduced include various modified silicones, for example, amino-modified silicones, polyether-modified silicones, and polyester-modified silicones, and other organic silicone compounds, for example, dimethyl silicones, having a low viscosity of 30 cst at 25°C.
- the fluoroalkyl group-containing compounds include fluorine compounds, for example, perfluoroalkylethers, perfluoroalkyl sulfonates, and perfluoroalkyl sulfonic acid amides.
- fluorine compounds for example, perfluoroalkylethers, perfluoroalkyl sulfonates, and perfluoroalkyl sulfonic acid amides.
- the oiling agent usable for the present invention it is important that it comprises, as indispensable components, three components. Further, the oiling agent optionally contains a usual emulsifying agent, higher alcohol, higher fatty acid, glycol compounds, and a small amount of an additive consisting of an organic or inorganic compound, antistatic agent, and amide compound, for example, diethanol amide of a fatty acid.
- the stages at which the oiling agent emulsion is applied in accordance with the present invention is not limited to specific occasions, as long as it is after the melt-spun polyester filament yarns are solidified.
- the emulsion is applied to the yarns in front of a taking-up roller.
- the oiling agent emulsion of the present invention is applied to the yarns, for example, to an extent such that an effective component of the oiling agent is imparted to the yarns in an amount of 0.35 to 1.0% based on the weight of the yarn through a metering oiling nozzle.
- the application method is, however, not limited to the above-mentioned one.
- the viscosity of the emulsion can be reduced, and by using the specific siloxane compound or fluorine-containing compound (component (b)) together with the component (a), the emulsion surface tension can be reduced, and thus the uniform adhesion of the oiling agent to the filament yarns moving at a high speed can be enhanced and the load stress generated due to a contact of the oiling applying device with the filament yarns can be reduced.
- the resultant oiling agent system since the polyoxyalkylene glycol copolymer (component (a)) is contained in a specific amount, the resultant oiling agent system, as a whole, can cause the oiling agent membrane strength to be enhanced to such an extent that even in the filament-forming conditions at a speed of 3000 m/min or more, the resultant oiling agent membrane becomes satisfactorily resistive to the load applied to the filament yarns, and thus a reduction in the lubricating performance of the oiling agent membrane can be prevented, namely, the reduction in high pressure lubricating performance is small.
- the resultant oiling agent exhibits, as a whole, a low viscosity, and thus a friction between the filament yarns moving at a high speed and yarn-guiding members can be reduced.
- the oiling agent-adhered polyester filament yarns produced by the method of the present invention exhibit an excellent resistance to friction between metal and filaments and between filaments with each other, and thus the weaving procedure can be effected, without difficulty and disturbance. Also, since the polyester filament yarns of the present invention are produced by a high speed filament-forming procedure, a fabric (woven fabric or knitted fabric) having a good touch can be produced.
- the number of fluffs in the filament yarns and the friction resistance of the filament yarns were determined in the following manners, respectively.
- the friction resistance of the filaments in relation to a metal (F/M) and the friction resistance between the filaments with each other (F/F) were measured by the methods as shown in Table 2, respectively.
- a yarn consisting of 36 filaments were produced by melt extruding a polyethylene terephthalate resin having an intrinsic viscosity [ ⁇ ] of 0.64. After solidifying, a 10% aqueous emulsion of the oiling agent comprising the components as shown in Table 3 was applied in a total amount of 0.4% by weight of effective components based on the weight of the yarn to the filament yarn by using a metering oiling nozzle. Then, the oiled filament yarn was taken up through a taking-up roller at a peripheral speed of 4000 m/min, and successively drawn at a draw ratio of 1.5 between the taking-up roller and a drawing roller. A drawn yarn having a yarn count of 50 denier/36 filaments was obtained. The resultant filament yarn was subjected to the above-mentioned tests and the test results were evaluated. The evaluation results are shown in Table 3.
- the high speed process of the present invention for producing polyester filaments can cause the load to be applied to the filament yarns in an oiling step to be reduced, and friction between the filaments and metal members and between the filaments with each other to be appropriately reduced, and thus can produce polyester filament yarns having fewer fluffs and an excellent resistance to abrasion at a high speed. Therefore, the process of the present invention is very useful for practical use.
