I am an independent trainer operating in the fields of textiles and man made fibre in South Africa.

I recently compiled a series of man made fibre [public domain] learning material and resources aimed at plant operators with a Junior High School level of education. [these are for use in our National Qualifications Framework (similar to NVQ) at NQF level 2]
The module titles are:
History and development of the Man Made Fibres Industry.
Properties, benefits and uses of man made fibres.
Manufacture of polymers suitable for conversion into man made fibres.
Production of man made fibres through melt, dry and wet extrusion processes.
A Detailed overview of a typical Single Stage Process. [polyester]
A Detailed overview of a typical Multi Stage Process. [polyester and nylon]
A Detailed overview of a typical Staple Fibre Production Process. [polyester]
[practical elements include: Operating a melt extrusion process and operating fibre finishing processes [drawtwist-draw wind, stretchline etc.]

I have subsequently been asked to develop man made fibre learning materials for trainee supervisors at Senior High School level for use in our local Technikon. [NQF level 4]
The main requirements therefore are to 'go' deeper into the above modules/subjects [ie. how does an extruder actually work - various drying systems/techniques - engineering properties into man made fibres etc. etc.]
The modules will contribute to the subject: Man Made Fibres Trade Theory.
The practical aspects will include setting up and starting, operating and stopping extrusion and fibre finishing plants.
