The present invention relates to an oil agent for obtaining polyurethane elastic fibers with low stickiness between threads and good smoothness. Polyurethane elastic fibers have greater adhesiveness than ordinary synthetic fibers with low elasticity, so the threads wound around the bobbin tend to stick together after spinning. Therefore, warping,
When used for knitting, the yarn does not unravel easily, causing various problems such as yarn breakage and surface roughness. Various methods have been studied to prevent the sticking of elastic fibers. The first method is to internally add a compound that is easy to release from the mold, such as polyethylene or paraffin, to the urethane resin. Although the adhesiveness can be improved to some extent by adding multiple compounds, the elastic recovery rate of the polyurethane elastic fiber is Also, there is a drawback that instantaneous recovery power decreases. The second method is to apply powder such as talc to the thread, but it is difficult to adhere the powder uniformly, causing partial adhesion or scattering of the powder, which not only worsens the working environment. It also has the disadvantage that it can get mixed in between mechanical devices, accelerating their wear and tear. The third method is to attach a so-called oil agent based on mineral oil or higher alcohol to the filament, but this method does not reduce the adhesive strength sufficiently, so the drawbacks have yet to be rectified. do not have. The present inventors have made extensive studies to solve these drawbacks by improving the properties of oil agents, and have discovered that oil agents containing organic fluorine compounds with a limited structure exhibit good effects, and the present invention has been made. This is what we have come to complete. That is, in the present invention, (A) has 3 to 18 carbon atoms in one molecule.
perfluoroalkyl group, and (B) a carbon number of 4 to 24
An organic fluorine compound having one or more of alkyl groups, polyalkylene oxide groups (the alkylene unit has 1 to 4 carbon atoms, and the number of repeating units is 3 to 50), or polysiloxane groups. The present invention relates to an oil agent for polyurethane elastic yarn characterized by containing: The perfluoroalkyl group referred to in the present invention is a perfluoroalkyl group in which 80% or more (number ratio) of the hydrogens on the alkyl group are substituted with fluorine atoms, and at the same time, the number of carbon atoms in which the hydrogen in the terminal methyl group is completely substituted with fluorine atoms is 3 to 18 pieces,
Preferably, the number of alkyl groups is 5 to 15, and if the number is less than this, the effects of the present invention will not be exhibited.
If there are more than 18, the chains are too long and production is difficult. The perfluoroalkyl group may have any shape, such as linear, branched, or cyclic, and may have oxygen atoms interposed between carbon atoms, such as (CF 3 ) 2 CFOCF 2 CF 2 . The number of carbon atoms in the alkyl group in the present invention is 4 to 24
The number is preferably from 6 to 18; outside this range, the compound often does not have compatibility with other oil components. The polyalkylene oxide group referred to in the present invention is
Consists of repeating alkylene oxide groups having 1 to 4 carbon atoms. Repeat unit is 1 to 40,
It is preferably from 5 to 20; outside this range, the compound often lacks compatibility with other oil components. The terminal of the polyalkylene oxide may be a hydroxyl group or an alkoxyl group having 4 or less carbon atoms. The weight content of fluorine in the organic fluorine compound is 2 to 60%, preferably 6 to 40%,
If it is outside this range, it will be difficult to obtain sufficient effects. The molecular weight is from 300 to 200,000, preferably from 600 to 20,000; if it is smaller than this, it evaporates too easily, and if it is larger than 20,000, the compatibility of the compound with other oil components is often poor. Furthermore, the organic fluorine compound of the present invention is
It is characterized by having both (A) a perfluoroalkyl group and (B) one or more of an alkyl group, a polyalkylene oxide group, or a siloxane group, but does not contain other bonding groups or functional groups. It is permissible to have both in a proportion that does not impair the effects of the invention. The organic fluorine compounds of the present invention can be roughly divided into two types depending on the bonding mode between the perfluoroalkyl group and the alkyl group, polyalkylene oxide group, or polysiloxane group. One is ()
The terminal functional group of a perfluoroalkyl group is reacted with the terminal functional group of an alkyl group, a polyalkylene oxide group, or a polysiloxane group, or is bonded via a polyfunctional compound, or an alkylene oxide is added, or A group of compounds that are co-hydrolyzed silanes containing perfluoroalkyl groups, and generally have a low molecular weight.
Specific examples include the following. Such compounds () can be easily produced from their corresponding precursors according to conventional methods. The other one is a copolymer of () a radically polymerizable monomer containing a perfluoroalkyl group and a polymerizable monomer containing an alkyl group, a polyalkylene oxide group, or a polysiloxane group. A group of compounds that generally have high molecular weights. For example, the perfluoroalkyl group-containing monomer () includes the following compounds.

The polymerization is generally carried out in a solvent at a weight ratio of 90/10 to 90/10 using a radical polymerization initiator and a mercaptan as a molecular weight regulator. Of course, monomers containing functional groups such as shorter-chain alkyl acrylates or 2-hydroxyethyl methacrylates, for the purpose of lowering crystallinity, lowering the melting point, or for other purposes, will not impair the effects of the present invention. It is permissible to carry out multicomponent copolymerization to a certain extent. The organic fluorine compound having both a perfluoroalkyl group and a siloxane group as used in the present invention can be obtained by cohydrolyzing a perfluoroalkyl group-containing silane or a perfluoroalkyl group-free silane. The number of bonds or repeating units of siloxane groups is not particularly limited. The organic fluorine compound is generally liquid or oily at room temperature. Therefore, although it is sufficiently effective as an oil agent by itself, it is often mixed with other oil components to form an oil agent for economical and other reasons. The compound that can be used as another component may be any compound that is sufficiently compatible with the organic fluorine compound of the present invention and does not reduce or inhibit the adhesiveness of the polyurethane elastic thread, but in general, Mineral oil, dimethylsiloxane, silicone oil such as oxyalkylene-modified dimethylsiloxane, higher aliphatic alcohol, higher aliphatic alkylphenol, polyalkylene ether, Examples include ester modified products thereof, liquid paraffin, low molecular weight polyethylene, water, and organic solvents. The oil agent of the present invention contains 0.1 to 0.1% of the present organic fluorine compound.
Preferably, the content is 30% by weight, particularly 0.5 to 5% by weight. If it is less than 0.1% by weight, no effect can be expected, and if it is more than 30% by weight, economic efficiency will be impaired. The organic fluorine compound may increase the amount of these oil component components attached to the elastic thread, reduce the surface/interfacial energy, or act as a type of surfactant. The polyurethane elastic fibers referred to in the present invention include:
It is a segmented copolymer consisting of a high melting point crystalline portion and a low melting point amorphous portion. The high melting point crystalline part is polyurea, polyurethane, bisurein polymer,
It is made of polyamide, and the low melting point amorphous part is made of polyester, polyether, and polylactone. Polyurethane elastic yarn is obtained by melting, dry or wet spinning a linear elastomer in which both parts are bonded with urethane using an isocyanate base. Of course, it is not limited to polyurethane elastic yarns that tend to cause manufacturing problems due to adhesion between yarns. Although synthetic fibers have more or less disadvantages, the oil agent of the present invention can be used as an anti-stick oil agent for almost all synthetic fibers. In addition, oil agents are effective not only for preventing sticking, but also for improving workability problems such as lowering the friction and smoothing the yarn. Examples are given below to explain the present invention in more detail. In the text, "%" and "parts" refer to % by weight and parts by weight unless otherwise specified. Examples 1 to 9, Comparative Examples 1 and 2 Methylenebis(4-phenyl isocyanate)
500 parts and 1000 parts of polytetramethylene oxide with an average molecular weight of 1000,
A chain extension reaction was carried out with 67 parts of 1,2-propylene diamine in a dimethylformamide solution, and the final polymer concentration was adjusted to 20% by weight. A sheet with a thickness of 50 μm was prepared from this polymer solution by a dry method. Cut this sheet to 10 x 5 cm, fold it in half to 5 x 5 cm, and apply 0.3 of the specified blend of oil between them.
~0.4g was applied uniformly. This folded sheet was pressed with a creep tester at 120° C. for 5 minutes under a load of 40 g/cm 2 . Return the sheet to room temperature, cut it into 1.5cm x 5cm strips, grab both ends, and perform a 180℃ peel test (tensile speed 300mm/
