Method for Measuring Static Potential on Moving Fabrics (by Erkmen Ercan)-1

 

 

l  Abstract

• No clear explanation for static potential generation
• Many factors that affect charge generation
  • Environment (temperature, humidity)
  • Structural (polymer type, structure of fabric)
  • Working factors (fabric speed, tension, contact area between fabric and machine parts, and  material type that is in contact with fabric)
• Static potential on a moving web can cause web breakage, ignition of flammable atmosphere, or shock risk.
• The main objective of this research is to develop a method to measure static electricity on moving nonwoven machine belts.
• tests were done by using a spunbond (부직포를 만드는 대표적인 제조 방식. 녹인 고분자를 아주 가느다란 실로 뽑은 후 쿨링 및 늘림, 이후 압력 또는 열을 이용해 서로 결합) belt on an actual spunbond machine.
• A goal of manufacturing these belts is to reduce static electricity during production.
• Among all parameters that cause static charge generation, tension is the most important one.
• Separation (접촉 시 전하의 분리, triboelectricity) and contact area are also reasons for charge generation
• Static charge generation may not be same at cross direction (가로방향) on a belt.
• the only thing that was different was the tension.
