Introduction
Daily washing of textile end products generates fibre fragments which are discharged from washing
machine. The purpose of this test method is to collect materials including fibre fragments which are
discharged from the domestic washing machine through the washing process.
Although there are many types of washing machines used at home, ISO 6330 has been developed for
the domestic washing test method, which specifies the domestic washing machines and test conditions.
This document utilizes one of the standard washing machines in ISO 6330.
In addition, a care label is attached to textile end products in many countries of the world and this care
label specifies washing conditions to use in this document.
Due to the complicated internal structure of washing machines, the cleaning process of the machine
is very important to avoid contamination. This document proposes the checking method and the
requirements of the washing machine to be used in this document.
The identification and quantification of components contained in the collected materials through the
washing process are determined by applying ISO 4484-2.
The information gathered from this document can be utilized by the textile industry for the development
of textile end products to reduce or minimize shedding materials from textile end products through the
washing process.

4 Principle
A given mass of textile end products is washed in a domestic washing machine under certain
temperature and mechanical conditions for a given number of washing cycles. The material shed
through the washing cycles is collected in a filter bag which is attached at the outlet hose of the
washing machine. The collected materials in filter bag are transferred to the membrane filter and the
membrane filter with the collected materials are weighed in the weighing bottle. The membrane filter
and weighing bottle are prepared in combination. The mass of the collected materials is calculated by
the subtracting the original mass of the membrane filter and weighing bottle from the mass with the
collected materials. The mass of collected materials, the ratio of the mass of the collected materials
and the test specimen mass and the mass of the collected material per piece of textile end product are
reported.

9.3 Washing test of the test specimen
Mount the filter bag (5.2) to the outlet hose of the domestic washing machine (5.1) and tie up by cable
tie (5.6). Put the test specimens into the washing tub and run one test washing cycle of the washing
program.
The detergent may be used for washing test and the preferable detergent is introduced in Annex D.
When the multiple numbers of the test washing cycle are required, run the number of the washing
cycles as determined by the interested parties according to Annex E. An example of the results of the
multiple numbers of test washing cycles is shown in Annex E.
After completion of the washing cycle, remove the test specimens from the washing tub.
Then, run 2 empty washing cycles by the same washing program.
The number of empty washing cycles (2 empty washing cycles) after test washing was determined by
the results as shown in Annex C.
After completion of the empty washing cycle, remove the filter bag from outlet hose.
nd rd
For the 2 and 3 sets of the test specimens, run the washing test in 9.3.
9.4 Washing of the collected material from the filter bag
Prepare four (4) glass beakers (5.12) containing 1 l of water (6.1) separately. Wash the filter bags of 9.2
and 9.3 in the glass beakers by turning the filter bags inside out and carefully checking that there are
no fibre remnants. The solution in the beaker is the suspension solution of the collected materials.
Place the test specimen with outside side out, and with the zip up or button on if applicable, into the
washing tub.
9.5 Measurement of the mass of the collected materials
Prepare four (4) polycarbonate membrane filters (5.7) and four (4) weighing bottles (5.8) in
combination and separately, it is essential to keep each membrane filter/weighing bottle combination
consistent throughout the duration of the test. Measure the mass of the original membrane filter (5.7)
and a weighing bottle (5.8), respectively, and record them up to 0,1 mg and denoted as (M ).
f1
Membrane filters (5.7) are handled by tweezers (5.11). The membrane filter (5.7) shall be kept in the
weighing bottle (5.8) to prevent contamination from the environment.
Set the membrane filter (5.7) on a vacuum filtration device (5.9).
Filter the suspension solution of 9.4 by the membrane filters on a vacuum filtration device (5.9). Add 1 l
of water (6.1) to the beaker and wash the filter bag again and filter the suspension solution by the same
membrane filter. Repeat this procedure at least twice. Finally, wash the surface of the filter bag and
the inside of the beaker by water (6.1) using a wash bottle (5.10), and this suspension solution is also
filtered by the same membrane filter.
Place the membrane filter with collected materials into the original weighing bottle of 9.5 in combination
and dry for 2 h at (105 ± 3) °C in the oven (5.5). Then place the weighing bottle with the membrane filter
and collected materials in desiccator (5.13) to cool down to the room temperature.
Condition the membrane filter with the collected materials and the weighing bottle under standard
atmospheres in 7.1.

Introduction
Regarding human life, daily washing of clothes generates fibre fragments, which are discharged from
washing machine, passed through inappropriate or no wastewater treatments, flow into the river, and
then flow out into the ocean as the final sink.
Many papers have been published on the fibre fragments that are discharged from the washing of textile
products and are of great concern in the apparel industry. Among them, there is no clear evaluation
standard, and therefore they are adopting their own evaluation conditions.
The textile end product mentioned here is a finished clothing product such as shirt, pants, fleece, blouse,
etc., the home textile end products such as a blanket, a rug, etc., and does not include a cut test sample
of the fabric or the products.
Although there are many types of washing machines used at home, ISO has developed the ISO 6330
domestic washing test method, which describes the domestic washing machines and test conditions.
In addition, a care label specified by ISO 3758 is attached to textile products worldwide, and this care
label specifies washing conditions as well.
The purpose of this test method is to collect the fibre fragments, actually that is the collected materials
that are discharged from the domestic washing machine during washing.
Due to the complicated structure of the washing machine, the cleaning of the washing machines is very
important issue and this document proposes the verification of the cleanness of washing machine.
The identification or quantification of components contained in the collected material during washing
will be investigated by applying the ISO 4484-2.
It is considered that this information can be utilized by the textile industry for the development of
clothes, textile products, etc.

9.4 Weighing of membrane filter and bottle
Weigh 4 polycarbonate membrane filters (5.7) with weighing bottles (5.8) as a set by the analytical
balance (5.3). Record the mass of each set of membrane filter and bottle before testing (M ) to an
f1
accuracy of 0, 1 mg by using tweezers (5.12) for handling of membrane filter. To prevent contamination
from the environment, the membrane filter should be kept in a weighing bottle.
9.5 Washing out of the collected materials
Turn the filter bag described in 9.2.4 over and wash in a separate glass beaker (5.14) containing
1 l of water (5.11). Set the membrane filter prepared in 9.4 on a vacuum filtration device (5.9). This
suspension is filtered through the filter using the vacuum filtration device. Add 1 l of fresh water (5.11)
to the beaker again, wash the filter bag again and filter the suspension. Repeat the washing and filtering
operations from this filter bag at least twice. Finally, the surface of the filter bag and the inside of the
beaker are washed with running water (5.11) using a washing bottle (5.10), and the suspension is also
filtered by the vacuum filtration device.
9.6 Drying membrane filter with the collected materials and bottle
The membrane filter with collected materials is returned in the same bottle used in 9.4 and dried
temporarily for 2 h at (105 ± 2) °C in the oven (5.5). Then place the bottle with the membrane filter and
collected materials in desiccator to cool down to the room temperature.
