European foreword
This document (CEN/TR 17222:2019) has been prepared by Technical Committee CEN/TC 248
“Textiles and textile products”, the secretariat of which is held by BSI.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
1 Scope
The effects of synthetic nanoparticles on human health and the environment are still poorly understood
and therefore uncertain. In particular, it is unclear in which areas nanoparticles-dose caused negative
effects in the organism or in the environment (unknown dose-response relationship). The underlying
toxicological mechanisms and possible effects of nanoparticle exposure over long periods of time are
poorly understood.
In product advertisements on the Internet and in reports in international journals, especially the
functional properties of “nanotextiles” are described. The type of integration of the nanoparticles in
textiles is often described only sparsely. Therefore, the present document is based primarily on
research studies that include information on the integration of the nanoparticles in the textile material.
The purpose of the present document is to give some guidance on tests to nanoparticle release. The
determination of the release of nanoparticles could be performed either through quantification by
chemical analysis (5.1), or by determining the linting (5.2), for example.

3.1
nanoscale
size range from approximately 1 nm to 100 nm
Note 1 to entry: Properties that are not extrapolations from a larger size are predominantly exhibited in this
length range.

3.2
nanoscience
study, discovery and understanding of matter where size- and structure-dependant properties and
phenomena manifest, predominantly in the nanoscale (3.1), distinct from those associated with
individual atoms or molecules or extrapolation from larger sizes of the same material
[SOURCE: ISO/TS 18110:2015, 2.12]
3.3
nanotechnology
application of scientific knowledge to manipulate and control matter predominantly in the nanoscale
(3.1) to make use of size- and structure-dependent properties and phenomena distinct from those
associated with individual atoms or molecules or extrapolation from larger sizes of the same material

3.4
nanomaterial
material with any external dimension in the nanoscale (3.1) or having internal structure or surface
structure in the nanoscale
[SOURCE: ISO 19430:2016, 3.13]
Note 1 to entry: In Commission Recommendation of 18 October 2011 on the definition of nanomaterial
(2011/696/EU), the term “nanomaterial’ means “a natural, incidental or manufactured material containing
particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50 % or more of the
particles in the number size distribution, one or more external dimensions is in the size range 1 nm-100 nm”.
3.5
nano-object
discrete piece of material with one, two or three external dimensions in the nanoscale (3.1)
Note 1 to entry: The second and third external dimensions are orthogonal to the first dimension and to each
other.
[SOURCE: CEN ISO/TS 80004-1:2015, 2.2]
3.6
nanofibre
nano-object with two similar external dimensions in the nanoscale (3.1) and the third dimension
significantly larger
Note 1 to entry: The largest external dimension is not necessarily in the nanoscale.
Note 2 to entry: The terms nanofibril and nanofilament can also be used.
Note 3 to entry: See CEN ISO/TS 80004-2:2017, 4.4, Note 1.

3.7
nanoparticle
nano-object (3.5) with all external dimensions in the nanoscale (3.1) where the lengths of the longest
and the shortest axes of the nano-object do not differ significantly
Note 1 to entry: If the dimensions differ significantly (typically by more than 3 times), terms such as nanofibre
(3.6) or nanoplate (CEN ISO/TS 80004-2:2017, 4.6) may be preferred to the term nanoparticle.

nanotextile
textile incorporating nanoparticles
4 Nanoparticles in textile products
4.1 Textile manufacturing process
Various nanotechnologies can be used to produce “nanotextiles”.
The nanoparticles are:
a) integrated into the fibres, or
b) applied on the fibre surface (e.g. as a finish, a coating).
The present document is intended to clarify nanotextile manufacturing processes and application areas.
4.2 Application areas and products
Nanotechnology in the development of new materials in the textile industry is used:
• to improve existing functionality, or
• to produce a textile material with entirely new properties.
Foremost among the applications currently feasible are, in particular dirt and/or water-repellent and
antibacterial textiles and, although they are as yet produced on a very small scale, textiles which give UV
radiation protection and so-called “cosmetotextiles” (e.g. ladies tights) with woven-in nano-capsules
containing special body care substances. Bullet-proof vests containing carbon nanotubes are also
currently available, as are heat isolating and moisture-absorbent textiles.
Table 1 gives an overview of nanomaterials in relation to the possible properties of the “nanotextiles”.

4.3 Are nanoparticles released from nanotextiles?
As there are different manufacturing processes by which nanoparticles can be integrated in fibres or on
fibres, there can be variation in how tightly bound the nanoparticles are with the textile material. It is
these factors and the use to which the textile is subjected that determine whether and to what extent
nanoparticles can be released from it.
