Textiles -- Manmade filament yarns -- Determination of shrinkage in boiling water

ISO 18066:2015 specifies a test method for the determination of the boiling water shrinkage of non-textured and textured multifilament yarns (made of polyester, polyamide, polypropylene, cellulose fibre, etc.) Only automatic method is specified in this International Standard. This International Standard is applicable to manmade filament yarns of linear density less than 3 000 dtex. This International Standard is not applicable to partially oriented yarns.

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.

For an explanation on the meaning of ISO specific terms and expressions related to conformity

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

to Trade (TBT), see the following URL: Foreword — Supplementary information.

The committee responsible for this document is ISO/TC 38, Textiles, Subcommittee SC 23, Fibres and yarns.

INTERNATIONAL STANDARD ISO 18066:2015(E)
Textiles — Manmade filament yarns — Determination of
shrinkage in boiling water
1  Scope

This International Standard specifies a test method for the determination of the boiling water shrinkage

of non-textured and textured multifilament yarns (made of polyester, polyamide, polypropylene,

cellulose fibre, etc.)
Only automatic method is specified in this International Standard.

This International Standard is applicable to manmade filament yarns of linear density less than 3 000 dtex.

This International Standard is not applicable to partially oriented yarns.
2  Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of referenced document (including any amendments) applies.

ISO 139, Textiles — Standard atmospheres for conditioning and testing
ISO 3696, Water for analytical laboratory use — Specification and test methods
3  Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
shrinkage in boiling water

decrease in length of a specimen as a result of thermal treatment in boiling water, expressed as a

percentage of its original length, which measured under tension before and after treatment

4  Principle

Under specific condition, a test specimen is treated in boiling water. Shrinkage is calculated as variation

in length, measured before and after treatment.
5  Apparatus and materials
5.1  Skein winding reel

a) Reel with a circumference of (1 000 ± 2,5) mm, driven either automatically or manually.

b) A traversing mechanism to avert overlapping while a number of skeins being wound at the same time.

c) A tensioning device, to an accuracy of ±10 %, maintaining tension within the recommended limits.

d) A device to count the turns of the reel, preferably warning or stopping winding automatically, just

prior to the specified number of reel revolutions.

e) A mechanism to reduce the reel circumference is advisable for easy removal of the skein.

ISO 18066:2015(E)
5.2  Automatic shrinkage tester (see Figure 1).

a) Automatically application of the specified tension, appliance to measure the length of the specimen

and to calculate the shrinkage based on the length values.
b) Resolution of the length measurement is 0,05 mm .

c) Fitted with a specimen holder, over 600 mm high, in which a number of skeins arranged and

tested in succession. Each skein is applied with a 2,5 cN load, which remains throughout the whole

testing procedure.
