Abstract
A binding cord for a motor (i) reduces damage to a motor component that is bound with the binding cord, (ii) has high fastening properties when the binding cord is tied, (iii) does not loosen after the binding cord is tied, (iv) prevents fluff from falling off, and (v) is suitable for both mechanical binding and manual binding. A binding cord for a motor of the present invention includes a multifilament yarn made of synthetic fibers. The multifilament yarn is a bulked yarn that has a loop and a slack in the direction of the yarn axis. The multifilament yarn is preferably a non-torque type and processed by a fluid jet. The degree of bulkiness of the multifilament yarn is preferably 1.5 ml/g or more.

A binding cord for a motor, comprising:
- a multifilament yarn made of synthetic fibers,
- wherein the multifilament yarn is a Taslan finished yarn which is a bulked yarn with loops and bows that are formed of filaments constituting the Taslan finished yarn and protruding from a surface of the yarn,
- a degree of bulkiness of the multifilament yarn is at least 2 ml/g, and
- high temperature oil resistance of the binding cord expressed by the following formula is 50% or more:
- High temperature oil resistance (%)=(T′/T)×100,
- where T represents a tensile strength of the binding cord before a treatment and T′ represents a tensile strength of the binding cord after the treatment,
- the tensile strength T and the tensile strength T′ mean a tensile strength measured in accordance with JIS L1013-8.5.1, and
- the treatment includes putting the entire binding cord in a mixture of 0.5 wt % of water and 99.5 wt % of an automatic transmission fluid in a closed container, and heating the container so that the mixture in the container is maintained at 150° C. for 1000 hours.
