Ground your textiles

Static charge under control

In the daily use of textiles missing antistatic properties may be uncomfortable e.g. due to riding-up and clinging clothes during wearing, but also fluff and dust sticking to textiles.
Antistatic agents considerably facilitate the making-up of piece goods or the processing of yarns.  With technical textiles too missing antistatic properties may cause problems, e.g. spark formation with conveyor belts or filters.

How to distinguish the different fibres in terms of their antistatic behaviour?

Especially synthetic fibres, such as PES, PA, PP, but also cellulose acetate fibres tend to static charge during processing or use, i.e. to accumulate electric charge on the surface, which causes the mutual repellence of individual threads and fibres.
With synthetic fibres higher fibre moisture does not mean a quicker bypass electrostatic charge.
Cellulosic fibres are able to bind considerable quantities of humidity and, thus, electric charge can be quickly bypassed. But with these fibres too electrostatic charge may occur if they are over-dry or are worn or processed at low humidity.

With sufficient moistre on the fibre, usually no difficulties arise with cellulosic fibres in terms to static cling.
However, with natural protein fibres, such as wool and silk, problems with static charge may occur even in normal humid conditions?.

How do antistatic agents work?

Antistatic agents are products which counteract? or control electrostatic charge when using textiles or processing textile fibres.
