[Industrial Field of Application] The present invention relates to nylon 66 yarn. More specifically, regarding the nylon 66 multifilament obtained by spinning at a high speed of 3000 to 6000 m/min, the process performance of the post-processing (user) is not deteriorated even after the multifilament is stored for a long period of time. That is, it relates to a nylon 66 multifilament that does not generate white powder during warping, knitting, etc. even after a long period of time. [Prior Art] In recent years, high-speed spinning has been used to reduce costs in the production of nylon fibers.
High-speed spinning of nylon is generally 3000 to 6000 m/min.
The speed is preferably 4000 to 6000 m/min. The nylon fiber spun in this way has a birefringence Δn of 0.035 to 0.045 and a cutting elongation of 50.
~100%, preferably in the range of 50 to 80%, and has a flexible texture and uniform dyeability, so it is used not only in the false twisting field, but also in a wide range of applications such as textiles and tricots. has been done.
However, when the nylon 66 multifilament is coated with a conventional emulsion-based oil agent during the high-speed spinning process, the nylon 66 multifilament runs while coming into contact with guides and reeds when it is warped as a tricot or textile warp. Some of the white powder adhering to the surface of the single yarn falls off, but most of it adheres to the guides and reeds, and as the warper ages, the amount of adhesion increases, causing an abnormal increase in tension and causing yarn breakage, causing a problem. . On the other hand, an oil agent applied during high-speed spinning of polyamide filaments has been proposed in Japanese Patent Publication No. 31931/1983 for the purpose of improving textile defects (warp stripes) caused by oil agents mainly containing oleyl oleate. In addition, JP-A-60-215872 describes an oil composition for nylon 6POY (mainly composed of a copolymer of ethylene oxide and propylene oxide) that has good processing operability and yields high-quality processed yarn (with little fuzz).
It is proposed in the Publication No. However, when these oil compositions are applied to nylon 66 multifilament in a high-speed spinning process, a problem arises in that white powder increases in the warper or knitting process if used after long-term storage (for example, 10 months). In addition to the above, there are no proposals regarding oils for high-speed spinning nylon 66 multifilaments. There is a problem that occurs. In the field of high-speed spinning clothing, there is a known technology (Japanese Patent Publication No. 60-37222) that applies a straight oil agent (non-water-containing oil agent) during the spinning process, but in this case, the generation of white powder can be prevented, but the The area is filled with oil smoke due to the scattering of the oil agent, and removing this requires a large-scale collection device, resulting in an increase in costs. Furthermore, there is also the problem that the cost of the oil agent increases significantly. [Problems to be Solved by the Invention] As a result of the above-mentioned intensive study on the generation of white powder, the present inventors found that the degree of precipitation of white powder from nylon 66 multifilament produced by high-speed spinning is due to the addition of ethylene oxide (hereinafter referred to as EO) as an emulsifier. We discovered the surprising fact that there is a close relationship with the content of substances. The present inventors have developed an emulsion that is stable, inexpensive, meets post-processing performance, and uses no emulsifier.
As a result of intensive study on the formulation of an oil agent that would reduce the amount of EO adducts as much as possible, they discovered a method that would allow the emulsion to remain stable even when the EO adducts were reduced to 0 to 3 wt%, leading to the completion of the present invention. An object of the present invention is to provide a nylon 66 yarn that does not produce white powder as described above. [Means for solving the problems] The present invention consists of a nylon 66 multifilament having a birefringence △n of 0.035 to 0.045 and a cutting elongation of 50 to 100%, and the following oil agent is applied to the filament.
Nylon 66 characterized by having 0.3~1.5wt%
Yarn (a) Ethylene oxide adduct (3wt% or less),
Alkenylsuccinic acid, alkylimidazoline amphoteric acid, sodium alkyl alkylate sulfonate
or emulsifier and antistatic agent composed of 2 to 6 types of K salt, alkyl diethanolamide, Na alkyl phosphate, or K salt (25 to 60 wt%) (b) Smoothing agent of mineral oil and/or alkyl alkylate (75-40wt%) However, the number of carbon atoms in the alkyl group is 4-20. EO adducts are EO adducts of higher alcohols and
EO/PO adduct, PEG ester, castor oil EO adduct and EO/PO adduct, nonylphenol EO
Examples include adducts, polyethylene glycol, polyoxyalkylamine, trimethylolpropane EO adducts, and the like. The number of moles of EO may be 1 to 60. For brands spun at high speed using regular nylon 66 chips, the amount of EO adducts in the oil is 3 to 18wt.
%, preferably 3 to 10 wt%, can sufficiently prevent white powder.
For special brands spun at high speed using 66 chips, there is a lot of white powder, and the EO adduct in the oil has less white powder in the range of 0 to 3 wt%, more preferably 0 wt%. In other words, all individual components such as smoothing agents, emulsifiers, and antistatic agents are blended with no added EO. Examples of the oil component include alkenyl succinic acid, oleyl oleate sulfonic acid Na salt, oleyl diethanolamide, lauryl imidazoline amphoteric compound, oleyl alcohol phosphate Na salt, etc., but higher fatty acids and their Na and K salts may also be used. Those that are emulsifiers but also have an antistatic effect,
Although it is an antistatic agent, it also acts as an emulsifier, so it is difficult to distinguish between an emulsifier and an antistatic agent, so the expression emulsifier + antistatic agent is used as an emulsifier and an antistatic agent. Emulsifiers and antistatic agents are used to ensure the emulsion stability of the emulsion.
A content of 25 to 60 wt% is required, and if it is less than 25 wt%, emulsification will be poor, and if it is more than 60 wt%, the amount of smoothing agent will decrease and the smoothness of the nylon 66 thread will deteriorate, which is not preferable. The smoothing agent is mineral oil or fatty acid ester, and each may be used alone or in combination.
If the content of the smoothing agent is less than 40 wt%, the smoothness of the nylon 66 yarn will deteriorate and yarn breakage will increase during the spinning process and post-processing, which is not preferable. On the other hand, if it exceeds 75 wt%, the amount of emulsifier decreases and the emulsion stability of the emulsion deteriorates, which is not preferable. Therefore, in order to maintain the stability of the emulsion and prevent yarn breakage during spinning and post-processing, a range of 75 to 40 wt% is preferable. If the amount of oil applied during spinning is less than 0.3 wt%, smoothness and cohesiveness cannot be maintained, so thread breakage is likely to occur during the spinning process, and if it is more than 1.5 wt%, white powder will increase, which is undesirable. Therefore, the amount of oil attached to the nylon 66 multifilament is preferably 0.3 to 1.5 wt%.
More preferably, it is 0.5 to 1.0 wt%. The oil composition for nylon 66 yarn produced by high-speed spinning of the present invention has a white powder reducing effect on filaments that have a breaking elongation of 50 to 100%, and ordinary (conventional method) nylon 6 and nylon 66 filaments have a white powder reduction effect. 20% of the EO additives in conventional products.
An oil containing ~40wt% is fine. White powder is an oligomer unique to nylon 66, and because the orientation of the amorphous part of the multifilament spun at high speed is loose, EO adducts in the oil agent can easily enter the inside of the single filament along with water from the surface of the single filament, resulting in changes over time. It is thought that oligomers are precipitated. What is the amount of oil attached to nylon 66 multifilament?
2.06 g was added 4 times with 3 c.c. of dichloromethane using a rapid residual fat extraction device manufactured by Tokai Keiki Co., Ltd. (heating part
110℃) and calculated using the following formula. (Residual fat amount g/2g) x 100 [%] [Example] Next, the present invention will be specifically explained with reference to Examples. Example 1 Using a spinneret with 13 spinning holes, ordinary nylon 66 polymer was melted and discharged, cooled with cold air in a chamber under the spinneret, and the following water emulsion oil (10 wt%) was added during the spinning process. ) is added to the yarn at 0.7wt% and stretched over 4000m/without stretching.
A 40D/13F nylon 66 multifilament was made by winding it into a cheese shape using a min winder, and the generation of white powder was investigated. The compounded oil used in the present invention and the conventional compounded oil are shown below. The content of EO adducts is shown in the column to the right of the oil agent name, and EO adducts are marked with * in the left column.

を調べた。その結果を第２表及び第３図に示す。[Table] As is clear from Table 1 and Figure 3, the amount of white powder generated has a strong correlation with the content of EO adducts in the emulsifier.
If there are many EO adducts in the blended oil, white powder will increase. Therefore, it can be concluded that the main cause of white powder precipitation is EO adducts. Nos. 6 and 7 have a fatal disadvantage of having a large amount of EO adducts and, accordingly, a large amount of white powder. On the other hand, Nos. 1 to 4 of the present invention have a small amount of EO adducts, so the white powder is about 1/10 that of No. 7, which is an amazing effect. Example 2 Using a spinneret with 10 spinning holes, nylon 66 chips kneaded with 1.0 wt% of EO adduct antistatic agent were melted and discharged, cooled with cold air in a chamber under the spinneret, and the above-mentioned spinning process was carried out. Add 0.7wt% of each oil agent No. 1 to 7 described above without stretching.
A 30D/10F nylon 66 multifilament was produced by winding it into a cheese shape with a winder at a speed of 4500 m/min, and the generation of white powder was examined using the white powder test method described above. The results are shown in Table 2 and Figure 3.

According to the present invention, the nylon 66 yarn produced by high-speed spinning is inexpensive, and a water emulsion oil with good emulsifying properties is applied to the yarn using a gear pump system or an oiling roll system in the spinning process, so that the amount of oil applied to the yarn is 0.3 to 1.5wt.
%, more preferably 0.5 to 1.0 wt%, when spun at high speed using ordinary nylon 66 chips.
Regarding 40d/13f, the white powder that was previously generated at 38-150mg/Kg can be reduced to 10-18mg/Kg. Nylon 66 mixed with 1.0wt% EO adduct antistatic agent
For 30d/10f spun at high speed using chips, white powder of 120 to 360 mg/Kg was generated in the past, but 45
It can be suppressed to ~70mg/Kg. Therefore, high-speed spun nylon 66 yarns coated with oil agents No. 1 to 4 have a white powder prevention effect on both brands spun using regular nylon 66 chips and chips containing EO adduct antistatic agent. There is less white powder and stable performance can be obtained when warper warping and knitting are performed for textile warps or tricots.
