QFT; Quantum Field Theory can be used to explain (in its way) almost any phenomena under the sky and beyond. It  is the mathematical and conceptual framework for contemporary elementary particle physics. It is also a framework used in other areas of theoretical physics, such as condensed matter physics and statistical mechanics. In a rather informal sense QFT is the extension of quantum mechanics (QM), dealing with particles, over to fields, i.e. systems with an infinite number of degrees of freedom. It is a  widely discussed topic in philosophy of science, with questions ranging from methodology and semantics to ontology. QFT taken seriously in its metaphysical implications seems to give a picture of the world which is at variance with central classical conceptions of particles and fields, and even with some features of QM.
 

In triboelectric effect mechanical rubbing separates charges across the interface between two materials.

This phenomena can be explained using QFT. 

 

But, for such simple things which can be understood using the classical approach, is it necessary to go after QFT is the question here?

If you want a QFT model of triboelectricity, the following links can help.
