DETAILED DESCRIPTION OF THE INVENTION The present invention relates to stable spinning of intermediately oriented polyamide fibers of uniform quality at high speed.

Conventionally, in order to obtain intermediately oriented polyamide yarns, melt-spun polyamide fibers are taken off at a speed of around 4,000 mm (4) and wound into packages.
The problem with this manufacturing method is that because it is a high-speed system, the yarn that goes from the final godet roller to the winding machine tends to wind backwards on the final godet roller, and therefore cannot be wound with low tension, so it is difficult to wind the yarn backwards. It was necessary to wind it with high tension to prevent it from happening.

This reverse winding phenomenon is further accelerated to 5,000 to 7.0
00%, it becomes extremely noticeable. To prevent this reverse winding, polyethylene terephthalate fibers can simply be wound with high tension, but with intermediately oriented yarns such as polyamide, which have a large delayed recovery and have a low Young's modulus, winding with high tension will result in a large winding package. This resulted in a deterioration in the form and a significant decrease in the uniformity of the yarn.

In addition, in order to make an intermediately oriented yarn at high speed, it is wound around a pair of godet rollers at least once, and a 44 dtex, 9 fil yarn is wound with 12 to 15
Providing sufficient entanglement on the order of hook/rn is described in JP-A-52-110920 (FIG. 1). In this way, the lead pitch (
When spinning at high speed with a full Nelson angle) and one or more Nelson windings, the yarn tends to sway and fluff due to this lead pitch, so it is important to provide sufficient entanglement to reduce the generated fluff, etc. This is effective for hiding inside all threads.

However, on the contrary, disadvantages such as difficulty in yarn spinning, deterioration of the package, and deterioration of the properties of the tentatively twisted yarn occur. That is, when spinning thin fibers with high elongation and low Young's modulus, such as intermediately oriented polyamide yarn, at high speed, providing such convergence makes it difficult to thread the yarn onto the winding bobbin. In particular, this causes the paper tube blade to slip through, and in blade traverse type winders, problems such as gold thread falling off at the end face of the package and poor formation of the end face occur.

Moreover, the occurrence of loose loops during high-speed unwinding from the package,
An even bigger problem is that using this intermediately oriented yarn, the blooming of the false twisted yarn as a yarn decreases.

Therefore, the first objective of the present invention is to stably and easily spin polyamide intermediately oriented fibers, and the second objective is to obtain a good package and good yarn quality. The purpose of No. 8 is to make it possible to obtain a uniform processed yarn without any defects from the processed yarn obtained by processing the obtained yarn.

The object of the present invention is to provide a method for producing an intermediately oriented polyamide yarn, in which a polyamide synthetic polymer is melt-spun, oiled, hung on each side on a set of non-heated godet rollers, and then wound at a speed of 4,000 yen or more. In the process, between the oil supply and the final godet roller before the winding, the air treatment nozzle is used to apply compressed air of 1% or more, and the OF value of the wound yarn is determined. number of filaments)
This is achieved by a method for producing intermediately oriented polyamide yarn.

When winding polyamide intermediately oriented yarn spun at high speed, such intermediately oriented yarn undergoes spontaneous elongation due to moisture absorption and crystallization, so the tension of the yarn decreases while being passed around the Godet roller at high speed, and therefore, when winding up, the yarn tension decreases. It is extremely easy for the yarn to sway greatly. Furthermore, when such a godet roller system is used at high speeds, the surfaces of the pair of rollers are usually finished with a satin finish, so they can be wound without reverse winding even under relatively low tension. This will further reduce the yarn sway. Moreover, when a large number of yarns are processed simultaneously on these pair of godet rollers, interference between the yarn systems tends to cause yarn breakage, fuzz, single yarn movement, etc.

However, in the present invention, since the yarn is hung on a pair of rollers having parallel axes, the force of swinging of the yarn is essentially generated as in Nelson winding. Therefore, it is possible to stably reel yarn with sufficient gripping force.

On the other hand, in the method of hooking the yarn on one set of mirror-surfaced rollers, the Godet roller has sufficient gripping force, so the thread has a high stable limit tension that prevents reverse winding. By installing an air processing nozzle in between and processing the film with compressed air at a pressure higher than 1, it became possible to wind it stably with low tension without reverse winding. Also, the entanglement caused during this treatment is calculated based on the number of filaments F of the yarn. By doing the following, yarn sway on the final godet roller causes interference between yarns during multi-yarn processing, yarn hooking during winding decreases, package defects increase, and processed yarn characteristics using this intermediately oriented yarn This makes it possible to prevent a decrease in

In other words, instead of controlling fuzz, single winding, etc. by strongly entangling the yarn, converging multifilaments, and making them into monofilaments, as in the past,
It has become clear that giving appropriate migration to the single yarns in the yarn and replacing all the single yarns that are about to be reverse wound at the exit of the goder roller is effective in preventing reverse winding. This is different from the conventional method of providing strong entanglement. For example, even with a two-filament yarn that does not have any entanglement at all, which was impossible to do in the past, by applying the air treatment of the present invention, the stable limit tension for reverse winding is 6 g. This is a significant decrease from 3 kuhe (17 denier yarn).

In this sense, the air treatment nozzle used in the present invention has conventionally been
A counterflow type nozzle that can stably cause migration between single yarns, rather than a high-entanglement type traveling flow type that is suitable for high-speed entanglement of 4,000'5'5> or more, or a vibration type nozzle. is suitable.

Further, this air treatment pressure needs to be 1) or higher. At a low pressure of less than 1-1, it is difficult to provide sufficient migration to a yarn running at a high speed of 4,000- or more, and low-tension winding is not possible. On the other hand, if the pressure exceeds 8%, the applied oil will be shaken off too much, damaging the yarn and causing a complete decrease in strength and elongation, so a pressure of 31% or less is preferable.

The location for providing this air treatment must be after refueling after spinning from the spinneret. Air treatment before refueling
For yarns with a low Young's modulus and relatively low elongation, such as polyamide intermediately oriented yarns, this method does not damage the yarn, but rather excites vibrations in the thinning and assimilation region. Therefore, it is not suitable. On the other hand, in order to lower the limit tension for reverse winding and to wind stably with low tension, air treatment must be performed before the final godet roller.

Since the fixed length stress of polyamide intermediately oriented yarn is reduced by heating, one set of Godet rollers needs to be unheated, and in particular, the final Godet roller needs to be unheated from the viewpoint of stable yarn running.

The processing nozzle is preferably located in front of the first godet roller from the viewpoint of ease of processing during multi-filament processing and prevention of yarn sway due to processing (FIG. 2). However, when processing the entire yarn at ultra-high speed, where the single yarn is thick and migration is difficult to occur, the stress in the yarn between the first godet roller and the final godet roller is relaxed and the spinning tension is low. Therefore, it is preferable to carry out compressed air treatment between the first Godet roller and the last Godet roller, since air treatment is easy (FIG. 3).

It is effective in cases where it is difficult to stably wind one winding of intermediately oriented polyamide yarn using the conventional method, such as when the yarn is 4,500% or more. That is, the method of the present invention is necessary for high-speed silk spinning such as 4,000 to 2 or more, and 4,000'/l,
It is not necessary to apply the method of the present invention to low-speed silk spinning. On the other hand, the winding speed range of the present invention is substantially 7.0

In addition, the intermediately oriented polyamide yarn in the present invention preferably has a denier of 1O or more in order to counter the accompanying airflow, air resistance, guide resistance, etc. at ultra-high speeds, and to avoid the influence of increased tension due to excessive accompanying airflow. In particular, it is preferable that the number of filaments is 50 or less. Furthermore, in order to fully utilize the effect of the present invention of low tension, it is preferably 250 denier or less, particularly 150 denier or less.
