“…In textiles, most of the materials are polymers, and their frictional electrification has been investigated by rubbing fiber against fiber [8], fiber against cylinder [9], yarn against cylinder [10,11,12], film against cylinder [13], fabric against cylinder/roller [14], and plastic disk against disk [15]. It is evident that their reported observations were not consistent and in some cases conflicted with each other.…”

The electrostatic charge on nylon, polypropylene (PP), and polytetrafluoroethylene (PTFE) after rubbing against stainless steel and against each other was examined using a newly developed rubbing device with automated features. It is observed that the charge generated on PTFE and PP increases as the contact force increases, while the charge generated on nylon is not affected by the contact force. It is also found that the charge generated on PTFE and nylon due to friction is more than that due to repeated contacts and separations, however, this difference was not observed on PP. Furthermore, the charge generated on these three polymers is not affected by the rubbing speed at the levels of 27, 47, 95 mm/min. In addition, the triboelectric series of these three polymers and stainless steel is investigated by rubbing against each other.

In this study, a mechanical model was introduced to analyze the hair wrapping via a contact surface in the yarn formation zone. Worsted and ramie/cotton rovings were then used to produce yarns on an experimental ring frame with and without a delivery rubber roller to validate the theoretical analysis. Yarn properties, including hairiness, unevenness, and tensile properties were tested and the results indicated that the delivery roller could stop fibers from escaping from the twisting process in the spinning triangle and wrap most of them onto the stem of the yarn. In particular for worsted spinning, yarn unevenness CV, as well as tensile properties, was improved significantly due to an improved arrangement of the worsted strand when using the front delivery rubber roller. However, yarn evenness and tensile properties deteriorated for ramie/cotton yarn spun with a delivery rubber roller. This was mainly because of the high modulus of the ramie/cotton blend strand, as upstream twists were blocked and a weak spinning zone was formed to incur an unexpected drawing.
