Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a spinning process which is applied immediately after melt spinning of polyester fibers and boria fibers during the production process or processing (especially false twisting process) of synthetic fiber multifilaments or filament filaments. It concerns oil agents.

In the manufacturing process of synthetic fibers, it is recognized as one of the important technical fields to apply oil immediately after spinning so that the subsequent processing of the fibers can be carried out smoothly.

However, oils for treating synthetic fibers are generally aqueous emulsions.
or water I! It is often applied to fibers as a single liquid. In this case, it is necessary that the emulsion or aqueous solution is stable to the extent that there are no operational problems, but the following phenomena should also be noted.

In other words, foaming is likely to occur in the emulsion soda or aqueous wave circulation system (between the stock tank and oil cylinder bath) adjusted to apply to synthetic fibers, and when the foam is introduced to the oil cylinder bath, the oil agent In addition, even if there is no foaming in the circulation system, very stable thin bubbles are likely to be generated in the thread path on the oiling roller during oiling, which also causes problems in the adhesion of oil to the fibers. It is a hindrance to

This phenomenon is an extremely important problem especially in high-speed spinning at a winding speed of 2.000117 minutes or more.

Moreover, the problem of foaming often occurs not only in the spinning process but also in the processing process and can cause trouble. For example, in the weaving process using a water jet loom, the water used to blow away the weft yarns washes off the oils adhering to the weft and warp yarns and dissolves them in the water, resulting in foaming around the heddles, resulting in poor weft conveyance, blocking of the healds, etc. 11 ct.
It has been pointed out that these problems are largely caused by the spinning oil.

A large number of organic compounds and compositions thereof have been proposed as synthetic fiber spinning oils in the past, and among them, polyalkylene ether derivatives form one of the most useful organic compounds for this application.

As the polyoxyalkylene ether derivative, a copolymer of 1,2-propylene oxide and ethylene oxide has been well known, and the excipient compound is a thermoplastic synthetic fiber,
U.S. Pat.
No. 830, Japanese Patent Publication No. 52-470711, etc.

Another example of a polyoxyalkylene ether derivative is a block addition polymer of L2-butylene oxide and ethylene oxide, which is disclosed in U.S. Pat. No. 3,834,935 I.
41111856-9475, etc., random copolymers of L4-butylene oxide and ethylene oxide or boupylene oxide are described in %Tosho No. 52-213, 1
Block addition polymers of 4-butylene oxide and ethylene oxide are described in US Pat. No. 4,245.004.

However, emulsions or aqueous solutions of oil containing these compounds are problematic because they are prone to the above-mentioned problems due to foaming.

In the case of oil containing a copolymer of propylene oxide and ethylene oxide, foaming is particularly likely to occur, and this is caused by the coexistence of the copolymer and an ionic or nonionic surfactant. This is because the foam film becomes unstable.

In addition, in the case of an oil containing a block addition polymer of 1,2-butylene oxide and ethylene oxide, the properties of the surfactant become stronger and completely eliminate the foaming suppressing effect of the oil emulsion or water III, which is the essence of the present invention. It is a random addition polymer of 1,4-butylene oxide (tetrahydrofuran) and ethylene oxide or propyle/oxycyto.

1. An oil agent containing a block addition polymer of 4-butylene oxide, ethylene, and nitrogen has the disadvantage that it tends to become solid because the wrinkled addition polymer has a linear shape and structure. No foaming suppressing effect of oil emulsion or aqueous solutions was observed.

Furthermore, attempts have been made to use silicone antifoaming agents to eliminate these bubbles, but no satisfactory effect has yet been achieved. .

In view of the above-mentioned situation, the present inventors have discovered the heat resistance 4I (anti-tar property), which is an advantage of the addition polymer of L2-propylene oxide and ethylene oxide, which has been widely used as a main component of lubricating agents for synthetic fibers. It maintains excellent lubricity (resistance to emulsion) and excellent lubricity, but its drawbacks are emulsion leakage or water! As a result of intensive studies to improve the high foaming property in liquids, a random addition polymer of L2-butylene oxide and ethylene oxide has lubricating properties and heat resistance equivalent to that of an addition polymer of L2-butylene oxide and ethylene oxide. It has been confirmed that the aqueous emulsion or aqueous solution has surprisingly low foaming or antifoaming properties even in the presence of a surfactant, and that the above-mentioned drawbacks can be sufficiently improved. It was reached.

The object of the present invention is to provide a synthetic fiber that is excellent in smoothness and heat resistance, and has fewer troubles due to foaming in the emulsion or aqueous solution circulation system or oiling, and can be used to speed up the spinning and processing processes of Huiwei fibers. The purpose of this invention is to provide a treatment oil agent, and the gist thereof is as follows.

That is, the present invention provides poly-9 (1,2-oxybutylene-oxy ethylene) ether derivative (hereinafter abbreviated as metal compound of the present invention), the molecular weight of the poly(1,2-oxybutylene-oxyethylene) ether moiety is 1,200 to 10,00.
The present invention relates to an oil agent for treating synthetic fibers, which contains at least 30% by weight of a polyoxyalkylene ether derivative of 0 to 1, and is used in the form of an aqueous emulsion or an aqueous solution.

If the molecular weight of the compound of the present invention is less than 1400, there will be a lot of scattering during the heat treatment 11 such as false twisting, resulting in a problem of smoking tar. Moreover, if it exceeds io or ooo, the viscosity is too high and it is difficult to use.

Furthermore, 1,2
The weight ratio of -butylene oxide is more preferably 50% by weight or less from the viewpoint of stability of the aqueous emulsion or aqueous solution of the oil agent of the present invention, and preferably 10% by weight or more from the viewpoint of the foaming suppressing effect.

However, even if the weight ratio of 1,2-butylene oxide is 50% or more, the object of the present invention can be achieved by appropriately combining a nonionic or anionic surfactant as an emulsifier.

The metal compound of the present invention uses the above-mentioned alnylic starting material, alkali hydroxide, and boron trifluoride.

A catalyst such as tin tetrachloride is dissolved and charged into a stainless steel pressure-resistant reactor under a pressure of 1 to 5 Kg/txl) [1GG
It is obtained by simultaneously pressurizing 1,2-butylene oxide and ethylene oxide at a desired ratio and carrying out sequential addition polymerization at a reaction temperature of ~140°C. It is especially important to keep the reaction temperature within the above range; if it is lower than 100°C, there is too much difference in the reactivity between ethylene oxide and IJ-butylene oxide, so the same random heterogeneous It is difficult to obtain the a structure, and if the reaction temperature exceeds 140°C, depolymerization reaction tends to occur, which is not preferable.

The industrially advantageous alcohols used as starting materials for synthesizing the compounds of the present invention include methanol, lower alcohols such as butanol, otatanol, isooctator, isononanol, decanol, indecanol, dodecanol, and indrideka. synthetic alcohol that is a mixture of normal and isoforms with a carbon number distribution of 10 to 15, and reduced alcohol of coconut fatty acids.

The emulsifier component is a normal nonionic surfactant.

There are anionic surfactants and cationic surfactants, etc., and these ingredients are added to obtain a stable aqueous emulsion or aqueous solution.Anionic and cationic surfactants not only stabilize the emulsion but also prevent static electricity on synthetic fibers. It also has the effect of being an agent.

The amounts of the above-mentioned smoothing agent component and emulsifier component to be added are determined as necessary, but they may not be added if unnecessary.

The effects of the present invention are exhibited when the content of the compound of the present invention in the oil agent is 30% by weight or more, but since the conditions under which synthetic fibers to which the oil agent is applied generally vary widely, The optimum amount of the compound of the invention to be used in the oil of the invention is determined.

As mentioned above, the feature of the oil agent of the present invention is that it prevents foaming during the treatment process while maintaining the surface properties of the treatment system (low coefficient of friction, antistatic properties). Therefore, when the treatment system has relatively low levels of friction coefficient, electrostatic charge, etc. due to the mechanical conditions of the treatment process, it is preferred to use the compounds of the present invention alone to achieve the highest degree of foaming control in the treatment process. When the system is treated under conditions where the friction coefficient and the level of electrostatic charge are forced to be relatively high, the compound 3 of the present invention is used to maintain high fK in order to maintain the surface properties of the treated system and suppress foaming.
It is better to add 10 to 70 weight of a smoothing agent, antistatic agent, etc. to a compound of 90 to 99.
It is recommended to add 0.1 to 10 weight % of antistatic agent to 9 weight %.

The synthetic fibers to which the oil agent of the present invention is applied are polyester, polyand fibers, etc., and the oil agent of the present invention is used in polyethylene terephthalate POY which is wound at a winding speed of 2,000 to 4,0001117 minutes.
