The present invention relates to an improvement in a method of directly spinning and drawing polyamide fibers drawn at high speed at a low magnification and winding them at high speed. In recent years, in order to improve productivity, there has been a strong demand for faster melt spinning processes. As a method to satisfy this demand for higher speed, polyamide melt-spun yarn is cooled and solidified, and then an oil agent is applied to it.
We proposed a direct spinning, stretching and winding method in which the fibers are taken up at high speed by a first Godet roller, stretched at a low magnification between the first Godet roller and a heated mirror-finished second Godet roller, heat treated, and wound at high speed ( (Special Publication No. 57-35287, etc.) However, in this direct spinning and drawing method, in order to increase the heat treatment efficiency at the second Godet roller, the yarn is brought into close contact with the heated surface of the second Godet roller, which has a mirror-finished surface, so that the yarn is not easy to separate from the second Godet roller. There was a drawback that the second godet roller was prone to reverse winding of the yarn. This drawback becomes particularly noticeable when the winding tension is lowered to improve the wound package form. Therefore, as a result of studying a method to prevent yarn reverse winding on the second godet roller without damaging the yarn quality of the product yarn, and also winding a good package, we found that there is a problem between applying a non-hydrous oil and the first godet roller. The yarn is entangled relatively lightly (fluid pressure of 3 kg/cm 2 G or less), and the winding tension is set to (D/10 to D/3) g [D: total yarn fineness of the wound yarn ( The inventors have discovered that it is sufficient to keep the denier within the range of 100% (denier)], leading to the present invention. That is, in the present invention, a polyamide melt-spun yarn is cooled and solidified, then a non-hydrous oil is applied thereto, and the yarn is taken over a first Godet roller at a speed of 2000 m/min or more, and the surface temperature of the first Godet roller is Tg ~ ( Tm−10)℃
[Tg: glass transition point (°C) of the polyamide,
Tm: the melting point of the polyamide (°C)] and stretched to a stretching ratio of 2.5 times or less between a second godet roller whose surface was mirror-finished, and then heat-treated for 4000 m/
In the direct spinning, drawing and winding method of winding at a high speed of 1 minute or more, the yarn is subjected to an entanglement treatment between the non-hydrous oil agent and the first godet roller under a fluid pressure of 1 to 3 minutes.
Kg/cm 2 G with interlace type nozzle,
Alternatively, the winding is performed using a twisting type nozzle at a fluid pressure of 0.5 to 2.5 Kg/cm 2 G, and the winding tension at the time of winding is (D/10 to D/3) g [D: the entire length of the wound yarn. This is a direct spinning, drawing and winding method for polyamide fibers. Below, the first section outlining an embodiment of the method of the present invention will be described.
The description will be made with reference to FIG. 2, which schematically shows the diagram and another embodiment. The polyamide melt-spun yarn melted and discharged from the spinneret 1 by the usual method is cooled and solidified by the cooling device 2, then applied with a non-hydrous oil agent by the oil agent applying device 3, and subjected to an interlacing treatment by the interlacing nozzle 4. It is taken up by the first Godet roller 5, stretched between the first Godet roller and the second Godet roller 6, heat-treated when being wound around the second Godet roller 6, and further entangled by the second entangling nozzle 7 if necessary, for a length of 4000 m. It is hoisted into a package at a high speed of more than 1 minute. The oil applied in the method of the present invention needs to be a non-water-containing oil in order to avoid heat treatment spots (which cause dyeing spots) caused by moisture adhesion during heat treatment in the second godet roller. The non-water-containing oil agent may contain some water as long as the water content is 10% or less. As the interlacing nozzle 4 in front of the first godet roller,
Even with an interlace type nozzle that sprays fluid onto the running yarn to spread it and create entanglement, it is possible to twist and entangle the yarn by moving the fluid traveling direction away from the center of the running yarn. It may also be a twisting type nozzle. The degree of entanglement provided by this entanglement nozzle is determined by a fluid pressure of 1 to 3 Kg/cm 2 or by a fluid pressure of 0.5 to 2.5 kg/cm 2 G interlace type nozzle.
Kg/cm 2 G and a relatively mild entanglement obtained by a twisting type nozzle, for example,
The degree of interlacing (CF value) is preferably from 0.2 to 3 co/m, more preferably from 0.5 to 2.5 co/m. This degree of interlacing (CF value) is a value measured according to the method described in US Pat. No. 3,290,932. That is, a metal needle is inserted into a traveling yarn having a total yarn fineness D and a filament number F, the yarn tension generated between the metal needle and the winding roll is sensed, and the initial tension of the yarn tension is calculated as ( Adjust the yarn tension to 0.2×D)g, set the point where the running yarn tension is (0.2×D+D/F)g or more as the interlacing point, and measure the yarn length (=Lcm) up to the interlacing point 50 times, Take the average value (cm) and CF value =
Calculated by 100/. If the degree of entanglement is too low, the yarn will have poor convergence, causing large yarn breakage on the godet roller and causing yarn breakage, as well as yarn twitching at the exit of the second godet roller, resulting in yarn Inverse winding of the strips cannot be sufficiently prevented. On the other hand, if the degree of entanglement is too high, heat treatment spots will occur when the second godet roller is wound, resulting in dyeing spots and yarn spots in the product yarn. The first Godet roller is preferably a single non-heated roller, but may also be a heated roller or a pair of rollers. The speed of the first godet roller must be 2000 m/min or more; if this speed is too low, the fiber orientation during interlacing before the first godet roller will be too low, resulting in yarn unevenness, strength reduction, fluffing, etc. Occur. The stretching between the first Godet roller and the second Godet roller is carried out at a stretching ratio of 2.5 times or less, preferably 1.1 to 2.3 times. If the stretching ratio is too low, the elongation will be too high at 60-80%, making it impossible to give the product yarn an appropriate elongation (35-50%). On the other hand, if it is too high, the elongation of the yarn will be less than 30%, and fuzz and yarn breakage will easily occur, making it impossible to stably produce yarn. As the second godet roller, the surface temperature is Tg ~
(Tm-10)°C One roller (6 in Figure 1) is preferably used, but this roller may be a Nelson type roller that rotates many times between a pair of rollers or a separate type roller (second roller). 6) in the figure may also be used. When two or more multi-filament threads are simultaneously spun and drawn directly at high speed, it is preferable to use a method in which the threads are hung on one roller. The heating surface of the second godet roller is preferably mirror-finished from the viewpoint of heat treatment efficiency and yarn slip prevention, and its surface roughness is preferably 3S or less, more preferably 1S or less. The heating surface temperature of the second godet roller needs to be above the glass transition point (Tg) of polyamide and below (Tm-10)°C, which is 10°C lower than the melting point of polyamide, and further between 130°C and ( Tm
-30)°C is preferred. If this temperature is too low, the heat treatment effect will be insufficient, resulting in a defective wound package, resulting in large shrinkage and large shrinkage spots, making it unusable in practice. On the other hand, if it is too high, a phenomenon of yarn fusing occurs on the second godet roller, resulting in yarn breakage. In this way, the intertwined, drawn, and heat-treated yarn is wound up into a package, but in order to impart sufficient entanglement to the yarn after the second godet roller, the second entanglement nozzle 7 is used to further entangle the yarn. It is preferable. In the case of two yarns as shown in FIG. 1, the obtained yarn is wound up by the yarn guide 8, which distributes the two yarns, passes through the traverse fulcrum guides 9 and 9', and then is transferred to the winder 10. , 10' and rolled up onto drums 11, 11' to form a package. The winding tension during winding is the yarn tension measured at 12 positions after the second godet roller as shown in Figure 1, and this tension is required to be (D/10 to D/3) g. , more preferably (D/10 to D/5) g. If this tension is too low, the yarn sways greatly at the exit of the second Godet roller, causing reverse winding of the yarn and resulting in yarn breakage. On the other hand, if it is too high, the form of the winding package will be poor, resulting in collapse of the yarn layer of the package and crushing of the winding yarn tube. This winding tension can be adjusted by changing conditions such as the speed difference (relaxation rate) between the second Godet roller and the winder, the surface temperature of the second Godet roller, and the traverse speed of the winder. In this way, by applying a relatively light entanglement treatment to the yarn before the first Godet roller and setting the winding tension to (D/10 to D/3) g, the yarn can be reversely wound at the second Godet roller. will no longer occur, and will also be able to be rolled up into a good package. Therefore, according to the method of the present invention, polyamide fibers can be produced rapidly and stably by a direct spinning, drawing and winding method. Next, the present invention will be further explained by examples. Example 1 Sulfuric acid: Nylon 6 chips with a relative viscosity of 2.62 were heated at 270°C.
After melting, the material was melted and discharged through a spinning hole with a diameter of 0.3 mm and a number of holes of 24. The discharge amount is determined when the total yarn fineness of the wound yarn is 70.
Adjusted to be denier. Using the device shown in Figure 1, the spun yarn is cooled in a cooling cylinder, and 3 wt% of a non-water-containing oil with a water content of 1% is applied. Using a type nozzle, air entanglement is carried out at the fluid pressure shown in Table 1, and the air is taken up by a non-heated first Godet roller with a circumferential speed of 4500 m/min.
It was wrapped half around a heated second Godet roller with a surface temperature of 160℃ and a surface roughness of 0.8S, stretched and heat treated, and was then heated to a fluid pressure of 4Kg/cm 2 using an interlace type nozzle.
A second air entanglement treatment was carried out at G, and the material was wound up into a cheese shape on a paper tube using a winder. The value of the winding tension measured at position 12 in FIG. 1 was varied in various ways by changing the winding speed of the winder. The obtained wound package form was evaluated and expressed according to the following criteria. The width of the yarn layer in the axial direction of the package when the yarn begins to be wound on the paper tube, that is, the winding width of the lowest layer, is defined as Acm, and the width of the yarn layer in the axial direction of the package at the point where it swells to the maximum in the axial direction of the package is measured as Bcm. , the package swelling rate is calculated by B-A/A×100 (%). Then, it was expressed in three levels: 〇=package swelling rate 10% or less△=package swelling rate 10-15% ×=package swelling rate 15% or more. Furthermore, the staining spots on the obtained fibers were measured by the following method. The obtained fibers are knitted into a tube and coated with the dye Palatine.
Fast Black WAN 0.5wt% owf was stained at 60°C for 30 minutes and visually judged. 〇 = No uneven dyeing, good condition △ = Slight uneven dyeing × = Dyeing unevenness is so large that it cannot be used as a product yarn The fluid pressure of the air entanglement treatment and the degree of interlacing of the yarn are as follows. We got into a relationship. Fluid pressure 0.3Kg/cm 2 G → Interlace degree 0.1K/

得ることが困難であつた。[Table] By setting the winding tension in the range of 7 to 23.3 g and applying relatively mild entanglement by specific fluid pressure before the first Godet roller, reverse winding does not occur on the second Godet roller, and Nylon 6 fibers with excellent characteristics, having a good wound package form and no staining spots were obtained. In addition, if the air entanglement treatment before the first godet roller is not performed (No. 10,
11) or when the degree of confounding is too weak (No. 1, 2)
In this case, reverse winding occurs in the second Gode roller,
The winding was poor and the yarn could not be wound up properly. On the other hand, in cases where the degree of entanglement was too strong (Nos. 8 and 9), heat treatment spots occurred and the resulting product yarns were defective products with dyeing spots. Furthermore, when the winding tension is too low (No. 3),
If reverse winding occurs frequently and yarn cannot be spun, and the yarn is too high (No.
In case 6), the package form deteriorated and the quality of the product yarn deteriorated, making it impossible to obtain a good product yarn. Example 2 Nylon 6 chips with a sulfuric acid relative viscosity of 2.62 (containing 2 wt% titanium oxide as a matting agent) were heated at 265°C.
After melting, the material was melted and discharged through a spinning hole with a diameter of 0.3 mm and a number of holes of 10. The discharge amount is determined when the total yarn fineness of the wound yarn is 40.
Adjusted to be denier. Using the device shown in Figure 1, the spun yarn is cooled in a cooling cylinder, applied with 3wt% of a non-hydrous oil with a water content of 1%, and twisted at a position 2m away from the oiling position in the yarn running direction. The rotary type nozzle allows the fluid pressure shown in Table 2 to be used to
After being subjected to air entanglement treatment, it is taken up by an unheated first Godet roller, stretched between a heated second Godet roller with a surface temperature of 160°C and a surface roughness of 0.8S, and after heat treatment, a fluid pressure of 5 is applied using an interlace type nozzle.
Kg/cm 2 G secondary air entanglement treatment, winding tension 7g
It was wound up using a winding machine. Unless the speed of the second godet roller is set to 4000 m/min or higher, it is difficult to obtain fibers without uneven threads or fuzz, and if the first air entanglement treatment is not performed at a pressure within an appropriate range, good fibers without uneven threads or fuzz can be obtained. It was difficult to obtain it stably.
