Technical Field
The present invention relates to a treatment agent for elastic fibers containing a monoester compound (a) having a specific chemical structure, and an elastic fiber to which the treatment agent for elastic fibers is attached.
Background
Since elastic fibers such as polyurethane elastic fibers have a higher adhesion between fibers than other synthetic fibers, there is a problem in that when elastic fibers are spun and wound into a package (package) and then drawn out from the package for processing, it is difficult to stably unwind the package, and when the shape retention of the spun elastic fibers is low, the wound filaments of the package deform.
In addition, when the friction of the elastic fiber treatment agent is high, there is a problem of preparation stability of the elastic fiber treatment agent in addition to the occurrence of yarn breakage.
In order to solve these problems, a treatment agent for elastic fibers containing a smoothing agent such as hydrocarbon oil for improving the smoothness of elastic fibers has been proposed. For example, a treating agent for elastic fibers containing a base component and 0.01 to 30 mass% of a nonionic surfactant having an HBL of 3 to 15 (patent document 1); a treating agent for elastic fibers comprising a base component, water, 0.1 to 20 mass% of a lower alcohol having a hydrocarbon group of 1 to 15 carbon atoms or an alkylene oxide adduct of the lower alcohol, and 0.1 to 30 mass% of an emulsifier (patent document 2); an elastic fiber oil containing a polyoxyalkylene ether-modified polysiloxane having a polyoxyethylene skeleton content of 20 to 80 mass% in the molecule (patent document 3) and the like, but a treatment agent for elastic fiber has not been proposed to solve all of the above problems.

[ method of evaluating the frictional Property of treatment agent ]
A pyriform chrome plating needle (pin) having a diameter of 1cm and a surface roughness of 2S was placed between two free rolls using a friction measuring instrument (manufactured by EIKO SOKKI measuring instruments Co., ltd., SAMPLE FRICTION UNIT MODEL TB-1), and the contact angle of the polyurethane elastic fiber drawn from the polyurethane elastic fiber package (500 g roll) was set to 90 degrees with respect to the pyriform chrome plating needle.
A secondary tension (T2) on the exit side was measured at 0.1 second intervals when the device was operated at a speed of 100 m/min by applying 5g of initial tension (T1) on the entry side at 25℃and 60% RH. The coefficient of friction was determined from the following equation and evaluated based on the following criteria.

Immediately after spinning, a package of the dry-spun polyurethane elastic fiber to which each treatment agent was applied was mounted on the first drive roller, and the unwound Shu Zhi yarn package was wound around the second drive roller with a thickness of 2 mm.
The "feed-out speed" of the urethane elastic fiber from the first drive roller was fixed to be 50 m/min, while the winding speed of the urethane elastic fiber onto the second drive roller was gradually increased from 50 m/min, and the urethane elastic fiber was forcibly unwound from the package.
In the forced unwinding Shu Zhong, the winding speed V (m/min) at the time when the polyurethane elastic fiber no longer jumps between the delivery portion and the winding portion was measured, and the unwinding property (%) was obtained from the following calculation formula and evaluated on the basis of the following criteria.

(3) Evaluation concerning winding shape
[ evaluation method of winding shape ]
Each treatment agent was attached to a 44dtex/3fil multifilament dry-spun polyurethane elastic fiber at 5.0% by a roll-oiling method.
