Directives Published on Elastolefin and Amended Methods for Quantitative Analysis of Binary Textile Fibre Mixtures
March 2007 (07B-107)

Amendments to the following two Directives regarding the new generic fibre name Elastolefin were published in the Official Journal of the European Union on 2 February 2007 and will become effective the 20th day following publication: 

  • Commission Directive 2007/3/EC amending, for the purposes of their adaptation to technical progress, Annexes I and II to Directive 96/74/EC of the European Parliament and of the Council on textile names 
  • Commission Directive 2007/4/EC amending Annex II to Directive 96/73/EC of the European Parliament and of the Council on certain methods for quantitative analysis of binary textile fibre mixtures.

Member States are required to bring into force and comply with the Directives by the 2 February 2008. 

An Overview of the Changes to the Directives

Amendment 2007/3/EC Adds and Defines the Generic Name of Elastolefin: Annex I of Directive 96/74/EC on textile names is amended by adding the generic name Elastolefin with the following definition: 

“Fibre composed of at least 95% (by mass) of macromolecules partially cross-linked, made up from ethylene and at least one other olefin and which, when stretched to one and a half times its original length and released, recovers rapidly and substantially to its initial length”

Annex II inserts the agreed allowance of 1.50% for elastolefin, to be applied in determining the fibre percentages of a textile product.

Amendment to 2007/4/EC Revises Methods for Quantitative Analysis of Binary Fibre Mixtures:
This Directive amends Annex II to Directive 96/73/EC on methods for the quantitative analysis of binary textile fibre mixtures, in the following ways:

  • Specifies that in mixtures containing elastolefin, pretreatment of test samples should be carried out using acetone instead of petroleum ether.
  • In the case of mixtures of elastolefin and acetate, where acetone cannot be used for pretreatment, an aqueous solution of orthophosphoric acid and urea shall be used.
  • Inserts elastolefin into Chapter 2 “Special Methods – Summary Table” and subsequent methods, furthermore amending the correction factor ‘d’ to be used in calculation of elastolefin component in selected methods.
