Abstract
The invention provides a treatment agent for synthetic fibers, which can obtain good spinning performance with excellent fuzz resistance and good rubber adhesion when a reinforcing rope is manufactured, and synthetic fibers attached with the treatment agent for synthetic fibers. As a solution, a treatment agent for synthetic fibers is provided, which is characterized by comprising: a smoothing agent (X) containing a full ester compound (X1) of a polyhydric alcohol having 3 to 6 carbon atoms and a monohydric fatty acid having 8 to 24 carbon atoms, a nonionic surfactant (Y) containing an ether ester derivative (A) having a specific chemical structure and an ether ester derivative (B) having a specific chemical structure, and an ionic surfactant (Z).
Description
Technical Field
The present invention relates to a treatment agent for synthetic fibers and a synthetic fiber. More specifically, the present invention relates to a treatment agent for synthetic fibers which exhibits good process passability in a step of producing synthetic fibers and has good rubber adhesion in a step of post-processing, and a synthetic fiber to which the treatment agent for synthetic fibers is attached.
Background
In recent years, in the spinning process or the processing process of synthetic fibers, the speed has been increased, and fuzz or broken ends have been easily generated. Therefore, as a treatment agent for synthetic fibers for inhibiting these, a material containing a polyether obtained by adding a polyoxyalkylene to a polyol (for example, patent documents 1 and 2), a material containing an organozinc compound having a specific structure (for example, patent document 3), and the like have been proposed. However, these conventional treatments for synthetic fibers have a problem that the penetration between fibers of the treatment for synthetic fibers is insufficient, and fuzz and broken filaments cannot be sufficiently suppressed at the time of spinning or processing.
On the other hand, the obtained synthetic fibers are also widely used as industrial materials, among which reinforcing materials for rubber products such as tires, belts, hoses and the like are widely used. These rubber products are reinforced with a reinforcing cord obtained by treating twisted yarns made of synthetic fibers with an adhesive, and in order to improve the durability of the rubber products, the reinforcing cord is required to have sufficient adhesion to rubber. In order to meet this demand, a treatment agent for synthetic fibers has been proposed, which contains a compound obtained by adding a polyoxyalkylene group to a polyhydric alcohol and/or a polycarboxylic acid (for example, patent document 4). However, there is a problem that the rubber adhesiveness of the reinforcing cord obtained by treating the synthetic fibers to which these conventional synthetic fiber treating agents are attached with an adhesive is insufficient.
