[Industrial Application Field] 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 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 for the purpose of reducing costs in the production of nylon fibers. High speed spinning of nylon is generally 3000~6000m/
Normally, the speed is preferably 4000 to 6000 m/min. The nylon fiber spun in this way has a breaking elongation of 50 to 100% and a refractive index of △
It is characterized by n being in the range of 0.035 to 0.045, and because it has a flexible texture and uniform dyeability, it is used in a wide range of applications, including not only the false twisting field but also the textile and tricot fields. However, when nylon 66 multifilament is coated with a conventional emulsion-based lubricant during the spinning process of high-speed spinning, the nylon 66 multifilament travels while coming into contact with guides and reeds when warper warping is performed as tricots or warp yarns for textiles. ,
At that time, some of the white powder adhering to the surface of the single yarn falls off, and most of it adheres to the guide and reed, and as the warper ages, the amount of adhesion increases, and the tension increases abnormally, causing yarn breakage, which becomes a problem. ing. 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 oil oleate. In addition, JP-A-1989-1999 was published as an oil composition for nylon 6POY (mainly composed of a copolymer compound of ethylene oxide and propylene oxide) that has good processing operability and yields high-quality processed yarn (with little fuzz).
It is proposed in Publication No. 215872. 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 have been no proposals regarding oils for high-speed spinning nylon 66 multifilament, and if a normal oil is used for high-speed spinning by sliding it as is, the nylon 66
When using multifilament, there is a problem that white powder is generated. In the clothing field of high-speed spinning, 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. The air is filled with oil smoke due to the scattering of the oil, and removing this requires a large-scale recovery device, resulting in an increase in costs. [Problems to be Solved by the Invention] As a result of intensive research into the generation of white powder, the present inventors have found that the white powder produced from nylon 66 multifilament spun at high speed is due to the addition of ethylene oxide (hereinafter referred to as EO) to the emulsifier. We obtained the surprising finding that there is a close relationship with the content. The inventors of the present invention have conducted intensive studies on the formulation of an oil agent that makes the emulsion stable, is inexpensive, meets post-processing performance, and reduces the amount of emulsifier as much as possible, and has found that by using a combination of liquid higher fatty acids and EO adducts of emulsifiers, EO We have found a formulation method that allows the emulsion to be stable even when the amount of adducts is reduced to the maximum. 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%. On the other hand, nylon 66 thread ethylene oxide adduct characterized by having 0.3 to 1.5% by weight 3 to 18% by weight Liquid higher fatty acid whose alkyl group has 2 to 20 carbon atoms
4 to 30% by weight, smoothing agent and antistatic agent 93 to 52% by weight. In the present invention, EO adducts include EO adducts and EO/PO adducts of higher alcohols, PEG esters, castor oil EO adducts and EO/PO adducts, sorbitan EO adducts, and phosphorus antistatic agent EO. Examples include adducts, nonylphenol EO adducts, polyethylene glycol, polyoxyalkylamines, trimethylolpropane EO adducts, and the like. The number of moles of EO may be 1 to 60. If the EO adduct of the emulsifier is less than 3% by weight, the stability of the emulsion cannot be obtained, and there is concern about staining spots during post-processing. If the EO adduct of the emulsifier is 18% by weight or more, white powder will increase. Therefore, when the EO adduct is in the range of 3 to 18% by weight, the emulsion is stable and there is little white powder.
More preferably, the content is in the range of 3 to 10% by weight. Examples of liquid higher fatty acids include propionic acid, butyric acid, acrylic acid, and oleic acid. When the liquid higher fatty acid content is less than 4% by weight, separation of the emulsion tends to occur, and when it is more than 30% by weight, the amount of the smoothing agent decreases and the smoothness deteriorates, which is not preferable. Therefore, a range of 4 to 30% by weight is preferable. When the number of carbon atoms in the alkyl group of the fatty acid is 1, the degree of acidity is strong and the needles of the tricot knitting machine will rust. Furthermore, if the alkyl group has 20 or more carbon atoms, it will be solid and the emulsification of the emulsion cannot be improved. Therefore, the number of carbon atoms in the alkyl group of higher fatty acids is 2 to
20, which is liquid at room temperature is best. It is not well understood why the combined use of an EO adduct of an emulsifier and a higher fatty acid improves emulsifying properties even if the EO adduct of an emulsifier is reduced, but it is probably a synergistic effect. The smoothing agent is preferably a mineral oil or ester type smoothing agent with low viscosity. The antistatic agent may be an imidazoline antistatic agent, a phosphorus antistatic agent, a sulfonate, an amine antistatic agent, or the like. If the amount of oil applied during spinning is less than 0.3% by weight, yarn breakage is likely to occur because smoothness cannot be maintained.
If it exceeds 1.5% by weight, white powder will increase, which is not preferable. Therefore, the amount of oil applied is preferably 0.3 to 1.5% by weight, more preferably 0.5 to 1.0% by weight, based on the nylon 66 multifilament. The oil composition for high-speed spun nylon 66 yarn of the present invention has the effect of reducing white powder on filaments that have a breaking elongation of 50 to 100%. EO of
An oil agent containing 20 to 40% by weight of adducts is sufficient. 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
[%] The oil components attached to the threads were separated and quantified by column chromatography and preparative GPC (gel permeation chromatography) from a sample of nylon 66 multifilament extracted with carbon tetrachloride, and 1R in each fraction. (Infrared spectrophotometer) GPC, GPL (gel liquid chromatography) can be used for analysis. Next, the present invention will be specifically explained with reference to Examples. [Example] Nylon was produced using a spinneret with 13 spinning holes.
The 66 polymer was melted and discharged, cooled with cold air in a chamber under the spinneret, and in the spinning process, the following water emulsion lubricant (10% by weight) was added to the yarn at 0.7% by weight, and the yarn was stretched at 4000 m/min without drawing. I made a 40d/13f nylon 66 multifilament by winding it into a cheese shape using a winder. The emulsion stability and white powder generation of the emulsion used in the spinning process were investigated.

An emulsion with a concentration of 10% by weight was prepared. Collect 400 c.c. of this emulsion and put it in a 500 c.c. beaker and store it in a room at room temperature in an open state for 3 minutes.
The oil separation state of the surface layer of the emulsion was evaluated by the naked eye after being left in the sun on the following three levels. × There is a lot of oil separation (operation is not possible) △ There is some oil separation (operation possible) ○ There is no oil separation (operation possible) The results are shown in Table 1. <White Powder Test> The blended oil agents No. 1 to No. 7 shown above were emulsified in warm water to create an emulsion with an oil agent concentration of 10% by weight. When spinning nylon 66 multifilament at 4000 m/min using this 10% emulsion, 0.7% by weight of the oil component was applied using a gear pump before the winder (winding).
