Identification:
The following procedure will identify the three standard types of Lurex yarn:
1. Burn yarn sample - butyrate Lurex yarn has a rancid odour.
2. Immerse in isopropyl alcohol - butyrate Lurex (film portion) will dissolve, Lurex MM and Lurex MF are insoluble.
3. Stretch yarn sample - Lurex MM and Lurex MF exhibit a stretch of 120-150%, butyrate Lurex will stretch about 20-30%. The aluminium in Lurex MF fractures (separates) on stretching, the aluminium in Lurex MM does not fracture on stretching.

SUMMARY:
Constantly being designed with new and multiple functionality, it is an exciting time to be a part of the metal fibre industry. Metal fibres can most assuredly help to take textiles into areas they have never been before.
