The present invention relates to a treatment agent for elastic fibers capable of improving stability, and elastic fibers to which the treatment agent for elastic fibers is attached.
Background
For example, elastic fibers such as polyurethane elastic fibers have stronger adhesion between fibers than other synthetic fibers such as polyester fibers and polyamide fibers. Therefore, for example, when an elastic fiber is spun and wound into a package, and then pulled out from the package and supplied to a processing step, there is a problem that it is difficult to stably unwind the elastic fiber from the package. Therefore, in order to improve the smoothness of elastic fibers compared to conventional elastic fibers, a treatment agent for elastic fibers containing a smoothing agent such as silicone oil is sometimes used.
Conventionally, there have been known treating agents for elastic fibers disclosed in International publication Nos. 2016-. International publication No. 2016-129357 discloses a treating agent for elastic fibers, which comprises a base component such as silicone oil and a specific alkyl phosphate. Japanese patent No. 6328836 discloses a treating agent for elastic fibers, which contains a smoothing agent (containing a paraffin component in an amount of 40% by mass or more and an aromatic component in an amount of 10% by mass or less) and a compound containing a sulfur element. Japanese patent laid-open publication No. 2009-138282 discloses a treating agent for elastic fibers, which contains 0.01 to 10 mass% of a base component such as silicone oil and a quaternary ammonium phosphate salt. Japanese patent application laid-open No. 2017-203222 discloses a treating agent for elastic fibers, which contains a smoothing agent, a Guerbet alcohol having 12 to 24 carbon atoms, and a charge control agent.

Further, the shape characteristics of the elastic fiber to which the treatment agent is added, particularly the shape characteristics when wound in a cheese shape, can be improved. In addition, the antistatic property of the elastic fiber can be improved.
The above embodiment may be modified as follows.
The treatment agent of the present embodiment may further contain a component generally used in treatment agents such as a thickener, an antioxidant, and an ultraviolet absorber as a stabilizer or a charge control agent for maintaining the quality of the treatment agent, within a range not to impair the effects of the present invention.

Test group 2 (production of elastic fiber)
First, a solution (35%) of polyurethane, which is composed of tetramethylene ether glycol having a molecular weight of 2900, bis- (p-isocyanatophenyl) -methane and ethylenediamine, in N, N-dimethylacetamide was polymerized to prepare a polymer solution (a).
Next, as an antioxidant, a 2 to 1 (mass ratio) mixture of polyurethane, which is produced by the reaction of t-butyldiethanolamine with methylene-bis (4-cyclohexyl isocyanate), and a polycondensate, which is a polycondensate of p-cresol and divinylbenzene, was used to prepare an N, N-dimethylacetamide solution (35%) of the mixture as the other additive solution (B).
The solutions (a) and (B) were uniformly mixed in the proportions of 96% and 4%, respectively, to prepare a spinning dope.
Using the spinning dope thus obtained, a 44dtex/3fil multifilament polyurethane elastic fiber was spun by a known dry spinning method used for spandex. Then, the treatment agents shown in examples 1 to 26 and comparative examples 1 to 9 were applied to the filaments in a solvent-free (neet) state by roll oiling with an oiling roller located between the stretching roller and the stretching roller before winding. The elastic fiber subjected to the roll oiling in the above manner was wound on a cylindrical paper tube having a length of 58mm at a winding speed of 600 m/min by a winder using a surface driven winding method (surface drive) via a traverse guide capable of providing a winding width of 38mm, to obtain a package 500g of a dry-spun polyurethane elastic fiber. The amount of the treatment agent for elastic fibers deposited was adjusted so that the rotational speed of the oiling roller was adjusted to 5% of the total amount of the treatment agent. The antistatic property of the elastic fiber and the shape characteristics when the elastic fiber was wound into a package in a cheese shape were evaluated using the thus obtained dry-spun polyurethane elastic fiber package. The stability of the treatment agent was also evaluated. The evaluation method is as follows.
Evaluation of antistatic Properties
The resistance value of 10g of the polyurethane elastic fiber drawn from the package was measured using a resistance measuring instrument (model SM-5E manufactured by Toyo radio industries, Ltd.) under an atmosphere of 25 ℃ X40% RH, and the measured value was evaluated in accordance with the following criteria. The results are shown in the column "antistatic property" in table 3.
◎ preferably has a resistance value of less than 1.0 × 109Ω (no problem at all, stable operation).
○ good, resistance value of 1.0 × 109Omega is more than or equal to 1.0 × 1011Ω (slightly close to each other in the warping step, but the operation can be stably performed without any problem).
△ (slightly worse), the resistance value was 1.0 × 1011Omega is more than or equal to 1.0 × 1012Ω (there was approach in the warping step and attachment of fly in the circular knitting step, but there was no problem in workability).
× (bad) resistance value of 1.0 × 1012Omega or more (the approach in the warping step is serious, the adhesion of fly in the circular knitting step is also serious, and the operation cannot be performed).
Evaluation of stability of treatment agent
Using the treating agent for elastic fiber prepared in test group 1, the treatment agent was left standing at 25 ℃ for 3 months, and the stability was evaluated according to the following criteria. The results are shown in the column "stability of treating agent" in table 3.
Excellent: no precipitation and separation, and the same uniform state as immediately after the preparation.
O (good): a very slight clouding was produced, but the mixture was returned to a uniform state by stirring as it was immediately after the preparation.
X (bad): precipitation and separation occur, and the solution cannot be restored to a uniform state by stirring.
Evaluation of the shape of the cheese
For a package (400g package), the maximum value (Wmax) and the minimum width (Wmin) of the package width are measured, the swelling amount (bulk) is obtained from the difference (Wmax-Wmin), and the shape of the yarn package is evaluated according to the following criteria. The results are shown in the column "package shape" in table 3.
Excellent: the expansion amount is less than 4 mm.
O (good): the expansion amount is 4mm or more and less than 6 mm.
Δ (slightly worse): the expansion amount is more than 6mm and less than 8 mm.
X (bad): the swelling capacity is more than 8 mm.
From the evaluation results of the examples in table 3 with respect to the comparative examples, it is also understood that the treatment agent of the present invention can improve the stability of the treatment agent and improve the shape characteristics and antistatic properties of the elastic fiber.
