Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a challenge agent for synthetic fibers. More specifically, it relates to a novel fiber processing oil agent that imparts high smoothness and antistatic performance to fiber yarns in the manufacturing process and processing process 1 of synthetic fibers.

More than ever! j1. At 1% kneading, efforts are being made to speed up the filament manufacturing process to improve the maturation properties, but as well as speeding up the yarn speed, the yarn and various contact objects (for example, guides) have to be increased.

-Increase in contact pressure with (one-two, heater, etc.), heat 4611
The spinning conditions are also becoming stricter, such as an 11-degree increase. Along with this, the friction between the yarn and various contact bodies increases significantly, resulting in the occurrence of fuzz and yarn breakage due to damage to the fiber yarn, reduction in the life of the contact body due to friction MK of the contact body, and increase in the generation of frictional static electricity. Various problems (p-ra winding, yarn breakage, and quality deterioration) are significant, and production efficiency and quality are reduced, and the life of the trailing body is shortened, resulting in a significant increase in costs due to shortening of the exchange cycle, etc. There is a tendency to

For example, in the production of false-twisted crimped yarn, the frictional false-twisting method has been adopted in place of the conventional spindle method, and the speed of fL twisting has been dramatically increased. Even the frictional false twisting method has been further speeded up due to the advances in various machinery and equipment, and is now 400 to 600 V.
/min and even xOO(1+n/min), which high-speed machining is performed.At the same time, the heater temperature has also increased from the conventional range of 160 to 190℃ to 200℃
It has been raised to -230°C to 250°C. Moreover,
Under the harsh conditions of continuous heating and i% warming, guides, convenors, etc. that control and regulate fiber threads, thread guidance and tension,
- As a result of increased friction with tools, heat treatment heaters, etc.

The fiber threads are damaged, leading to fuzz and yarn breakage, resulting in a decrease in production efficiency.As another example, the production speed of woven and knitted products is increasing, and the production of reeds, knitting needles, etc. The increased friction of the threads causes damage to the threads and even more wear and tear on the reeds and needles. This axis is particularly busy.

On the other hand, at such high speeds, friction increases and l
As a result of the significant increase in the generation of frictional static electricity between various contacts with the 111IA yarn pike, the single yarn may become stuck in a part of the Kp-ts during threading or running during filament drawing and processing, and in some cases may break. This will cause threads to form, which will greatly reduce work efficiency. This phenomenon occurs when 1% is subjected to heat treatment. That is, since the generation of static electricity generally increases rapidly when the temperature is low, yarns that have undergone heat section at high temperatures, such as during false twisting, are in a nearly bone-dry state and are in a situation where static electricity is very likely to be generated.

On the other hand, under low tension, the thread is j! In the process described above, the yarn often comes off from the contact area and dust is generated on the yarn itself, resulting in a decrease in quality.The purpose of the present invention is to eliminate the above-mentioned undesirable effects, that is, the production of fiber yarn. As the processing conditions become more continuous and the temperature increases, the friction between the yarn and various contact bodies increases, resulting in damage to the yarn. ! Decrease in production efficiency caused by abrasion of the contact body (9) Based on the reduction in quality (9) In order to prevent the increase in costs and to succeed in innovative technology centered on high speed and aluminum alloy, The object of the present invention is to provide an oil agent for treating fibers that can impart smoothness and anti-static properties against warpage.

The inventors of the present invention have conducted various studies to achieve the above object, and have found that the lubricants that have conventionally been used to generally treat fiber yarns include smoothing agents and antistatic agents.

However, the present inventors believe that it is extremely difficult to overcome the various obstacles associated with increased feed speed and higher temperatures using existing II&M lubricants.
As a result of various studies in order to obtain even higher level of smoothness and antistatic performance, the inventors discovered that the above object could be achieved by using an oil agent containing a specific compound, and thus arrived at the present invention.

That is, the present invention provides polyvalent carbon II (At

This is an oil agent for treating synthetic fibers characterized by containing a salt (2) of heptamine or organic heptamine.

To describe the present invention in more detail, the gist of the present invention is to include the above-mentioned Ti content in the oil agent in order to give the oil agent a high degree of smoothness and antistatic performance.

Each of the components M to D will be listed below.

The compound of 俤): As the Sushiwa group 7 syl halide, a normal compound containing a higher grade Sushi fatty acid having 8 or more carbon atoms is used. For example, lauric acid p-lide, palmitic acid p-lide, myristic acid p-lide, stearic acid p-lide, oleic acid p-lide, etc. are used.

Compound (to); The compound obtained by +CI is combined with an alkali hydroxide such as lithium hydroxide, Iy-based soda, lff-based potash, etc.
It can be produced by neutralizing it with a flukanolamine salt such as ummoni-7 or monoethanolamine, jetanolamine, triethanolamine, etc., or a flukyl-7mine such as trimethylamine, triethylamine, tributylamine, and lavalylamine. Of course, these salts may be used alone or in the form of a mixture (the degree of neutralization is also complete).

The present invention uses the above-mentioned compounds in various conventional textile oil MKs.
The purpose is to provide a new oil having smoothness and antistatic performance by adding lubricants such as mineral oil, animal and vegetable oil, various synthetic ester lubricants, polyfulkylene/l coal-based lubricant, and synthetic silicone. This is achieved by addition of lubricants and their emulsifiers into an oil system. It is effective to add IL of 2% (weight) or more, and preferably %Ks to 20゜ (weight).

When using the oil agent of the present invention, either an aqueous emulsion method or a straight method may be used as the adhesion method, and the amount M of the adhesion may be determined depending on the purpose at the spinning stage, such as spinning or J11N drawing, or at various processing steps. This can be done at any step such as the # floor. In other words, when used as a spinning oil, fuzz and yarn breakage are reduced in the spinning and abrasive drawing processes, and furthermore, in the diameter adjustment process, yarn twisting process, etc. 3! It is also effective in the knitting process and the false twisting process to prevent static electricity damage and wear of the friction bodies of the guide rollers. Although the amount of oil applied differs depending on the above-mentioned twisting process 11, it is reasonable to select it within the range of 2 to 201 L (per fiber) for a false twisting process, for example. The oil agent of the present invention is effective for any synthetic fibers, including 4IK polyester, Boria! It exhibits an excellent effect on 'C% for multifilament yarns such as C.
