Description

— 1294001 (1) Field of the Invention The present invention relates to a method for producing a synthetic fiber having improved dyeability from a molten blend mainly composed of a fiber-forming matrix polymer. Including comprising a fiber-forming matrix polymer with at least one second amorphous additive polymer that is incompatible with the fiber-forming matrix polymer (based on the total weight of the fiber-forming matrix polymer and the additive polymer that is incompatible therewith) The step of blending from 0.05% by weight to 10% by weight. The invention also relates to synthetic fibers having improved dyeability and also to their use. More particularly, the present invention relates to polyester monofilaments having improved dyeability, and their use in the manufacture of multifilament yarns having improved dyeability, as well as further processing of monofilaments and multifilaments. The textiles, for example, are formed by stretch weaving to form fluffy yarns and also to form staple fibers and stretch crepe yarns. [Prior Art] A process for producing a synthetic fiber in a two-stage process, particularly a continuous polyester monofilament, such as polyethylene terephthalate (PET) monofilament, is known. In this method, the first stage comprises a raw yarn semi-oriented with a woven and a bobbin, and in the second stage, it is fully stretched and heat-fixed or stretch-woven into a fluffy yarn. The Buch Synthetische Fasern [synthetic fiber] by F. Fourne (1995) by Hanser, Munich provides a comprehensive overview of the art. However, only the production method of PET fiber is not described in the name of understandable textile technology, but it is explained in the form of investigation indicating all kinds of characteristics. -5 - 1294001 (2) A number of textile processes for making fully stretched or highly oriented monofilaments are known, and are described, for example, in Figure 1 of the Man-Made Fiber Year Book, September 1996, page 58. . A variety of textile polymers (including polypropylene, polyamide and polyester) are used to form a part of the DI document DE · A - 3 8 1 9 9 1 3. Very few synthetic fiber materials can be easily Dye into a satisfactory color. Therefore, it is in principle desirable for all synthetic fibers to have improved dyeing properties, especially with regard to shade depth. Synthetic fibers (for example, polyethylene terephthalate (PET) fibers) can be produced by concentrating into a polyester suitable for comonomers such as polyethylene glycol or 5-sulfoisophthalic acid to facilitate It imparts special properties to the polyester, such as improved dark disperse dye dyeability or improved bright cationic dye dyeability. However, the production of synthetic fibers having improved dyeability is relatively expensive and inconvenient considering the typical batch size of these applications, and can only be carried out in a small batch operation in a concentration plant. In addition, the synthesis of these copolyesters is more difficult than standard polyester synthesis, and due to the secondary reaction, the polymer uniformity and quality are worse than standard polyesters. Moreover, when a comonomer is introduced into a synthetic fiber (for example, 'polyester fiber') with its predetermined defect, it has an adverse effect on the textile properties. For example, it has a specific comonomer for improving dyeability. Some polyesters tend to have poor linear breakage rates. If the end breakage during textile operations is reduced, then the special polyester weave must be modified to take into account the changing polymer properties. Therefore, the textile method can Easily uneconomical, due to the low textile speed and reduced textile density for winter 129401 (3). WO 99/0 7 92 7 relates to polyester with a starting speed of at least 260 m/min v a predominantly polymer blend of p〇Ys, a blend of polyester and a second amorphous thermoplastically processible copolymer (having a glass transition temperature Tg of more than 1 °C) as an elongation enhancer And the ratio of the melt viscosity of the elongation extender to the melt viscosity of the polyester is in the range of from 1:1 to 10: 1. The polyester is added in at least 0.05% by weight of the copolymer, and added to the polyester. The maximum amount of copolymer The starting speed is determined by the following formula: Μ = 1600 [min - 0.8 [% by weight]. WO 0 1 /90454 discloses the use of a low residual monomer textile additive as an elongation enhancer in the production of synthetic fibers. Useful additives as described in WO 0 1 /9045 4 include the preferred terpolymers of methyl methacrylate (MMA), styrene and N-cyclohexylmaleimide. These elongation enhancers may include one or a plurality of small amounts of ethylenically unsaturated monomers copolymerizable with MMA, styrene and/or N-cyclohexylmaleimide, and selected from the group consisting of α-methylstyrene, vinyl acetate, acrylic esters, Methacrylic acid ester, acrylonitrile, acrylamide, methacrylamide, vinyl chloride, vinylidene chloride, styrene substituted with halogen, vinyl ether, isopropenyl ether and diene. The monomers required do not have any adverse effect on the properties of the copolymers used in accordance with WO 0 1 /90 0454. These monomers are especially used in order to modify the properties of the copolymer in a desired manner, for example 129401 (4), Add or improve in copolymer plus The flow characteristics when heated to the melting temperature or the reduction of any residual color in the copolymer, or the use of polyfunctional monomers to modify the properties of the copolymer, so that a specific degree of crosslinking can be introduced into the elongation enhancer. The optional monomer for the elongation of the reinforcing agent is selected so that the copolymerization of the component may be preferred or enhanced. In the case of maleic anhydride (MA) and methyl methacrylate (MMA), It is copolymerized as it is, but can be easily copolymerized when a third component (such as styrene) is added. WO 0 1/90454 specifically mentions especially esters of vinyl esters, acrylic acid (for example, methyl acrylate and acrylic acid). Ethyl ester, methacrylic acid ester other than methyl methacrylate (for example, butyl methacrylate and ethyl hexyl methacrylate), vinyl nitrile, acrylamide, methacrylamide, ethylene gas , partial-gas, fine, Benyi, ύ!-methyl benzene-ethyl and other various halogen-substituted styrene, vinyl ether and isopropenyl ether, diene (such as 1,3-butadiene) and Divinylbenzene as a special repair Representation of modified monomers. According to W Ο 0 1 / 9 0 4 5 4, it is particularly preferable to use an electron-rich monomer (for example, vinyl ether, vinyl acetate, styrene or methyl benzene) to achieve a reduced copolymer color. Thus, WO 0 1 /90454 only illustrates modifications of the elongation reinforcing agent (copolymer, trimer) itself. There is no improvement in dyeability of synthetic fibers in WO 0 1 /904 5 4 or WO 99/0792 7. Process for the production of staple fibers is described in, for example, DE Specification No. 1 9 9 3 772 7.8 (5) 1294001 [Invention] The object of the present invention is to provide an improved process for the manufacture of a molten blend based on a fiber-forming matrix polymer.

A further object of the present invention is to provide a synthetic fiber obtainable from a woven melt blend comprising at least one fiber forming matrix polymer and at least one polymer incompatible with the matrix polymer, the incompatible polymer Preferably, the (meth) acrylate polymer will have improved dyeability. A still further object of the present invention is to indicate the use of synthetic fibers having improved dyeability. More specifically, the dyeability of modified synthetic fibers (e.g., polyester monofilaments and multifilaments or fibers) will not lose its conventional textile physical parameters. The monofilament will combine improved dyeability with, for example, elongation at break in the range of > 60% (preferably from 90% to 165 %), high uniformity with respect to monofilament parameters, and low crystallization. degree.

Shape, no central raised and detached winding. The present invention makes it possible to further process semi-oriented polyester monofilaments in a simple manner in a stretching or drawing weaving operation, especially at higher or higher weaving speeds, at more than 4500 ft/min. good. (6) 1294001 More specifically, it will improve the dyeability of synthetic fibers, most particularly polyesters, without introducing artificial defects into the molecules of the synthetic fibers themselves and without adversely affecting their high-speed weaving ability. influences. More specifically, the amount of the additive conventionally used as the elongation enhancer does not change significantly, so that the parameters of the high speed spinning method may not need to be adjusted if necessary. The method of making synthetic fibers (which has all the features of claim 1) is not explicitly mentioned, but these and other objects can be easily derived or understood by the relevant events discussed herein in an introductory manner. Advantageous modifications of the method of the present invention are protected by the scope of the sub-patent of the first application of the patent application. The synthetic fibers obtainable by this method are described in the scope of the separate product application. The use of various synthetic fibers constitutes part of the subject matter of the scope of application for the classification of uses. Accordingly, the present invention provides a method of making a synthetic fiber from a molten blend based on a fiber-forming matrix polymer, which comprises the step of including a fiber-forming matrix polymer with at least one fiber-forming matrix polymer. a step of admixing two amorphous additive polymers (from 0.05% by weight to 10% by weight based on the total weight of the fiber-forming matrix polymer and the additive polymer incompatible with it), wherein a) Additive polymer (meth) acrylate polymer, which can be obtained by co- or tri-polymerization of aa) with a) to obtain aa) 50-99% by weight of at least one ethylenically unsaturated monomer a) 1 to 50% by weight of at least one monomer which may be copolymerized with aa) and selected from monomers different from those mentioned in aa), which are composed of -10- 1294001 (7) abl) Alkoxy polyethylene glycol mono(meth)acrylate of the formula i) CH2 = CRi-COO-(CH2-CH2-0) n-R2 i ) wherein R] is a H atom or a CH3 group, R2 is H Atom, C].] 5_hospital or C5_]2-cyclodecyl or C6.]4-aryl, and η is not less than 1 Integer, ab2) alkoxy polypropylene glycol mono(meth)acrylate of formula ii) CH2 = CR1-CO〇.

This unexpected method makes it possible to produce synthetic fibers with improved dyeability. More specifically, the method of the present invention is very variability and simple, suitable for a particular mechanical type and conforms to all commonly used methods of operation. In addition, it is a simple way to provide warp yarns and especially polyester yarns, combining excellent dyeability with excellent material properties and good yarn uniformity. The method of the present invention has many further advantages. These include ' • the method of the invention can be carried out in a simple manner on a large industrial scale and economically. More specifically, this method makes it possible to spin 1294001 (11) woven and winded yarns at high starting speeds. • The use of special functionalized textile additives makes it possible to achieve start-up speeds of up to 8 000 m/min and improved dyeability. It is therefore possible to operate the plant in a particularly economical manner. • One of the semi-oriented polyester fibril products obtainable by the process of the present invention can be further processed in a simple, economical and large industrial scale drawing or drawing weaving operation. For example, the POYs of the present invention can be stretched or stretched at a high speed (at a speed of more than 450 meters per minute and preferably at -700 meters per minute) and a small number of broken ends. • The process of the present invention is particularly useful for the manufacture of polyester-based POYs having elongation at break in the range of from 90% to 165%, high uniformity with respect to monofilament parameters, and low crystallinity. More specifically, higher elongation at break is obtained at higher spinning speeds than without additives, so higher draw ratios lead to further processing, which has a positive effect on the economics of the process. When used in monofilaments made from staple fibers, a higher positive effect on elongation at break is also achieved. • The production of specialty fibers starting with a standard polymer (preferably with a standard polyester) and then mixing in a functional additive also has the advantage of higher variability and flexibility. Improved filament dyeability is particularly likely to be affected and controlled by the additive nature of the matrix polymer that does not alter the synthetic fibers. It is therefore possible to modify the dyeability with respect to dark disperse dyes and/or the dyeability of bright cationic dyes, for example, by imparting synthetic fibers without changing the matrix polymer. -15&gt; (12) 1294001 The method of the present invention relates to a method for producing a synthetic fiber from a molten blend mainly composed of a fiber-forming matrix polymer, and particularly includes a spinning step therein.

The lower the residual monomer content of the textile additive, the lower the linear breakage rate in the woven or stretch woven fabric. Further, the ratio of the melt viscosity of the additive polymer and/or copolymer to the melt viscosity of the matrix polymer is selected from 1 · 0 : 1 · 0 to 1 4 · with the selected additive polymer and/or copolymer. Within the range of 1 and preferably in the range from 1 · 5 : j to 9 : 1. The melt viscosity referred to herein is measured in a known manner with an oscillating rheometer device at an oscillation frequency of 2 · 4 Η z and a melting temperature equal to the matrix polymer plus a temperature of 24 ° C. The temperature at which the melt viscosity of PET was measured was 280 °C. Further details can be obtained from published publication WO 99/07927. Preferably, the additive polymer and/or copolymer has a higher melt viscosity than the matrix polymer and has been selected for the particular viscosity range of the additive-25-(22) 1294001 polymer and/or copolymer. And the choice of viscosity ratio helps to perfect the fiber properties produced. The amount of additive polymer and/or copolymer added can be minimized at a perfect viscosity ratio, which in particular improves the economics of the process. The narrower additive polymer and/or copolymer particle size distribution is provided in the polymer matrix by selecting a favorable viscosity ratio, and the additive polymer and/or copolymer in the fiber has the desired fibril structure. The high glass transition temperature (compared to the matrix polymer) and also the high flow activation energy of the additive polymer and/or copolymer determines that the fibril structure will rapidly solidify in the thus woven fibers. Once present from the spinneret model, the additive polymer and/or copolymer has an average particle size of less than 1 000 nm. After extrusion of the textile thread, the fibers are brought to a favorable fibril structure, in which case the fibers comprise at least 60% by weight of the additive polymer and/or copolymer having a length: diameter ratio &gt; 10 fibril form ). The special variation of the process of the present invention utilizes a potassium salt of MMA, styrene and sulfopropyl methacrylate (having a comonomer fraction of 12% by weight based on the total weight of the terpolymer) (about A repeating unit based on the potassium salt of sulfopropyl methacrylate)) A commercially available additive polymer of terpolymer. More specifically, the process of the present invention allows for high speed spinning. In an advantageous embodiment of the process of the present invention, the web speed for manufacturing a semi-oriented monofilament that can be highly oriented and/or stretched can be set between 2500 meters/minute and 80. Between 0 0 m / min, the textile starting speed during fiber spinning operation is between 500 and 400 m / min, and in the case of the 2- (23) 1294001 stage method, It is preferably between 500 and 2,500 meters/minute.

A fiber obtainable from a blend of a matrix polymer-based polyester (preferably p E T (polyethylene terephthalate)) is selected. The particular achievement of this fiber of the present invention has an elongation at break in the range of from 60 to 16.5% of p 0 Y. Another preferred variation comprises fibers having an elongation at break in the range of from 18 to 45% of the DTY. Preferably, the fibers within the scope of the present invention have an elongation at break in the range of 25 to 50% as FDY, and in a further embodiment, have a concentration of 30 to 0% as HOY. Elongation at break in the range 〇 The invention also provides the use of a fiber as described herein for the manufacture of a multifilament warp yarn. These multifilament warp yarns are particularly useful in accordance with the present invention and are preferably manufactured in a stretch braiding machine at a speed of at least 50,000 meters per minute. Another option is that the present invention also provides the use of the fibers of the present invention as described herein to produce staple fibers and stretch crepe yarns in a draw ratio of from 100 to 400 meters per minute. Particularly preferably, in this manufacturing operation herein, a cotton grade of not less than 18% and not less than 25 °/ are obtained. The wool-like elongation at break is the staple fiber and the stretched crepe. The following is a exemplification of the use of polyester as an example for the manufacture of additive polymers and/or copolymers of monofilaments, but the subject matter and scope of protection of the invention is not to be given by -31 - (28) 1294001 An application to limit the cost of the invention. The polymer melt can be obtained directly from, for example, the final reactor of a polyconcentration plant or as solid polymer crumb in a melt press. The textile additive, especially in molten or solid form, can be metered into the matrix polymer in a known manner, where it is uniformly agitated and dispersed to form fine particles. Preferably, a device according to DE 1 00 22 8 8 9 can be used. In contrast to the direct weaving process, the textile additive may also be included in a compound formed, for example, in the form of a polyester in the form of chips or granules. In the process of the present invention, the melt or melt blend of the polyester is compressed by a textile pump apparatus operating at a fixed rotational speed (adjusting the rotational speed according to a familiar arithmetic formula to obtain a desired fiber linear density). The liquid melt monofilament is formed into the model set and extruded through the model holes in the model plate of the set. The melt can be produced as polymer crumb in, for example, an extruder, in which case it is particularly advantageous to pre-dry the chips to a water content of 50,000 ppm, in particular a water content of S 3 5 p p m. The so-called textile temperature and the temperature of the melt measured upstream of the textile chest are dependent on the melting point of the polymer or polymer blend used. Preferably, it is within the range provided by Equation 1: Equation 1:

Tm+15°C ^ TSp^ Tm + 45〇C (29) 1294001 where

Tm: melting point of the polyester rc ] T s p : textile temperature [art] The hydrolysis and/or thermal degradation of the viscosity is specified with the specified parameters, and the degradation should preferably be as small as possible. Within the scope of the present invention, it is desirable to have a viscosity reduction of less than 0.12 metric gram per gram, especially less than 〇·〇 8 commensions per gram, and more particularly 〇.〇4 commensions/gram. The homogeneity of the melt has a direct effect on the uniformity of the material properties of the woven woven fibrils and fibers and also on their manufacturing properties. It is therefore preferred to homogenize the melt using a static mixer further having at least one component and a static mixer in the product line, which is installed downstream of the textile pump. The temperature of the model plate according to the textile temperature is controlled by feeding back the micro-heated model plate. Useful slightly heated forms include, for example, heating the textile enclosure with hot kerosene or conventional convection or radiant heaters. The temperature of the model plate is the same as the textile temperature. The temperature at the model plate can be increased via the pressure gradient in the model set. For example, the origins known in K. Riggert "Fortschritte in der Herstel" ung von Polyester-Reifenkordgarn" Chemiefasern 21, page 379 (1 9 7 1) indicate that the pressure drop per 〇 〇 bar increases by a temperature of about 4 °C. It is further possible to control the model pressure via the use of loose filter media, in particular via use having an average particle size between 0.10 mm and I · 2 mm - 33 - (30) 1294001 (to between 〇. 12 mm to A steel grit of preferably between 0.75 mm and/or a filter disc formed of a woven or nonwoven metal fabric having a fineness of $40 microns. In addition, the total pressure is formed by the pressure drop in the model holes. Preferably, the model pressure is set between 80 and 4500 bar, especially between 1000 and 250 bar. The extruded monofilament is passed through a quenching zone. The quenching delay zone is directly embedded under the model set and becomes a recessed area, so that the single filaments appearing from the model holes avoid the direct action of the cooling air and delay the extrusion or cooling of the textile thread. The activated portion of the recessed portion is configured as a model sleeve to the extension of the textile box so that the heated filament surrounds the monofilament. The passivation portion is formed by an insulating layer and an unheated frame. The length of the activation recess is between 0 and 100 mm and the length of the passivation portion is between 20 and 120 mm, depending on the total length of 30 to 200 mm, and preferably 30 to 120 mm. The reheater can be placed under the textile enclosure as an alternative activation recess. The cylindrical or rectangular cross-sectional area then comprises at least one heating system independent of the textile housing as compared to the activated recessed area. In a radial porous quench system surrounded by a straight line concentric, a cylindrical side panel can be used to achieve a quenching delay. The monofilaments are then cooled to a temperature lower than their curing temperatures. The curing temperature for the purpose of the present invention is such that the melt becomes a solid state. Within the scope of the invention, it has been determined that it is particularly advantageous to cool the monofilament to a temperature which is substantially no longer sticky. It is particularly advantageous to have the monofilaments cool -34 - 1294001 (31) to a temperature lower than their crystallization temperatures, especially at lower temperatures than their glass transition temperatures. Devices for quenching or cooling monofilaments are known from the prior art. According to the invention, it is particularly useful to use a cooling gas, especially a cooled air. The temperature of the cooling air is preferably in the range from 12 ° C to 35 ° C, especially in the range from 16 ° C to 26 ° C. The cooling air velocity is preferably in the range of from 0. 20 meters/second to 0.55 meters/second. For example, a single-ended system containing a single cooling tube (having a porous wall) can be used. Cooling of each individual monofilament is obtained via an activated cooling air supply or using the automatic pumping effect of the monofilament. It is also possible to use a familiar AC quench system as an alternative separate cooling tube. After the monofilaments have been cooled to a lower temperature than the cure point, they are combined to form a bundle of yarns. The method of measuring yarn speed and/or yarn temperature on-line can be used to determine the concentration point distance suitable for the surface of the model according to the invention, for example using a Dopper anemometer from TSI/Germany or IRRIS 160 infrared camera from Goratec/Germany. The distance is in the range of from 500 to 50,000 mm, and is preferably in the range of from 500 to 2,000 mm. The monofilaments are concentrated in a oil trap which supplies the desired amount of the finished fiber at a uniform speed. For example, these oil skimmers are available from Geramtec/Germany or Goulston/USA. In the case of producing staple fibers or stretching burrs from woven monofilaments, it is preferred to use a wide-bore oil sump or drum to perform concentration and oil-water coating and to use a ring slinger. -35- (32) (32) it 1294001 According to the invention, it is particularly preferred to first knead the fibers in the manufacture of the multifilaments prior to winding. It was found that the LD type system from Temco/Germany, the dual system from Slack &amp; Parr/USA or the Polyjets from Heberlein are particularly suitable for field applications. The surrounding speed of the first wrapped disk unit is referred to as the starting speed. Before the yarn is wound in a wrap combination, more wrap system can be used for, for example, stretching and/or heat fixation as needed before forming a bobbin (winding shaft) on the reel. And slack. φ The winding speed of P0Y (semi-directional yarn), HOY (high directional yarn) and FDY (fully drawn yarn) according to the present invention is between 2,500 m/min and 8 000 m/ Between minutes. It is better to select a speed between 3 000 m/min and 700 m/min. Particularly preferably, the polymer blend is wound at a speed ranging from 3,500 meters per minute to 7,000 meters per minute. The textile starting speed during the fiber spinning operation is 50,000 - 4 000 meters / minute according to the present invention, and in the 2-stage process, preferably 5 00 · 25 00 ft / ft / min, in the fiber section Subsequent stretching occurs from 1 400 to 400 meters per minute. The process for the preparation of the additive copolymers used according to the invention is known per se. The copolymer may be produced as a function of particular characteristics, especially in the form of a block, solution, suspension or emulsion polymerization or from a controlled monomer based on a controlled/reactive polymerization process. A useful hint for bulk polymerization is found in Houben-Weyl, page 1 of page 20 of the second volume. The solution polymerization method -36- 1294001 (33) was also found in page 5 of the pp. The suspension polymerization method is described on page 1 149ff of the same book, and the emulsion polymerization method is explained and demonstrated in the 1st 5th page of the same book.

Matyjaszewski, ISBN: 0 84 1 23 707 7 or in ''Controlled Radical Polymerization' ACS No. 68 5, April 1 997? by M atyjaszewsk i.

Those skilled in the art are well aware of the methods used to determine the reported material parameters. These methods can be taken from the technical literature. Although most of the parameters can be determined in different ways, the following methods for determining the monofilament parameters prove to be particularly advantageous within the scope of the invention: Measurement at 25 ° C in a U bbe 1 〇hde capillary viscometer Intrinsic viscosity.

The polymer pellets were then placed under a nitrogen blanket on a temperature controlled measuring plate from a UM 100 cone and plate rheometer from Physica Mey?technik GmbH, Stuttgart/Germany. After the sample was melted (ie after about 30 seconds), the measuring cone (MK21 0 ) was placed on the measuring plate. The measurement was started after reheating for 60 seconds (measurement time == leap seconds). The measured temperature of the polyethylene terephthalate and the additive polymer added to the polyethylene terephthalate is 280 ° C, or equal to the melting temperature of the polymer in question plus 2 4.0 it . It is therefore defined that the measured temperature of (38) (38) v 1294001 is equal to the typical processing or weaving temperature of a particular polymer.
