Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 24,

Conditioning atmospheres and physical tests for textile fabrics, in collaboration with the European

Committee for Standardization (CEN) Technical Committee CEN/TC 248, Textiles and textile products,

in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 12945-3:2000), which has been

technically revised.
The main changes compared to the previous edition are as follows:

— in Clause 10, visual assessment of pilling, fuzzing, and matting have been carried out according to

ISO 12945-4.
A list of all parts in the ISO 12945 series can be found on the ISO website.

ISO 12945-3:2020(E)
Introduction

Pills are formed when fibres on a fabric surface “tease out” and become entangled during wear. Such

surface deterioration is generally undesirable, but the degree of consumer tolerance for a given level of

pilling will depend on the garment type and fabric end use.

Generally, the level of pilling which develops is determined by the rates of the following parallel

processes:
a) fibre entanglement leading to pill formation;
b) development of more surface fibre;
c) fibre and pill wear-off.

The rates of these processes depend on the fibre, yarn and fabric properties. Examples of extreme

situations are found in fabrics containing strong fibres versus fabric containing weak fibres. A

consequence of the strong fibre is a rate of pill formation that exceeds the rate of wear-off. This results

in an increase of pilling with an increase of wear. With a weak fibre the rate of pill formation competes

with the rate of wear-off. This would result in a fluctuation of pilling with an increase of wear. There are

other constructions that the surface fibre wear-off occurs before pill formation. Each of these examples

demonstrates the complexity of evaluating the surface change on different types of fabric.

The ideal laboratory test would accelerate the wear processes a), b), and c) by exactly the same factor

and would be universally applicable to all fibre, yarn, and fabric types. No such test has been developed.

However, a test procedure has been established in which fabrics can be ranked in the same order of

pilling, fuzzing, and matting propensity as is likely to occur in end use wear.

Particular attention is drawn to Annex A which gives advice on the maintenance and checking of the

apparatus and liners. It is recommended that Annex A be studied prior to carrying out the procedure.

Annex C gives rationale especially regarding the testing of napped fabrics.
