AATCC150服装自动家洗时尺寸的变化
Developed in 1977 by AATCC Commit-tee RA42; editorially revised and reaf-firmed 1979, 1984, 1992; editorially revised 1983, 1985, 1989, 1990, 1991, 1996, 1997, 2004, 2005; revised 1987, 1995, 2001, 2003 (with title change); reaffirmed 2000. Related to ISO 3759.
1. Purpose and Scope
1.1 This test method is for the determi-nation of dimensional changes of gar-ments when subjected to home launder-ing procedures used by consumers. Four washing temperatures, three agitation cy-cles, two rinse temperatures and four dry-ing procedures cover the common home care options available to consumers using current laundering machines.
1.2 The dimensional changes of gar-ments subjected to home laundering care procedures are measured using bench-marks placed on designated areas of the garments. Measured dimensional changes may be affected by garment construction, tensions, sewing threads or trims in addi-tion to fabric dimensional change.
1.3 As an optional procedure, fabric dimensional changes may be determined by using benchmarks placed on the fabric in areas of the garment that contains no seams or sewing.
1.4 This method may not be applicable for garments made of certain stretch fabrics.
2. Principle
2.1 The dimensional changes of gar-ment specimens subjected to home laun-dering care procedures are measured us-ing benchmarks applied to the garment before laundering.
3. Terminology
3.1 dimensional change, n.—a ge-neric term for changes in length or width of a fabric specimen subjected to speci-fied conditions. The change is usually ex-pressed as a percentage of the initial di-mension of a specimen.
3.2 garment, n.—a shaped article of textile fabric, or other flexible material, intended to cover portions of the human body.editorially
3.3 growth, n.—a dimensional change resulting in an increase of length or width of a specimen.
3.4 laundering, n.—of textile materi-als, a process intended to remove soils
and/or stains by treatment (washing) with
an aqueous detergent solution and nor-
mally including rinsing, extraction and
drying.
3.5 shrinkage, n.—a dimensional
change resulting in a decrease in the
length or width of a specimen.
4. Safety Precautions
NOTE: These safety precautions are
for information purposes only. The pre-
cautions are ancillary to the testing proce-
dures and are not intended to be all inclu-
sive. It is the user’s responsibility to use
safe and proper techniques in handling
materials in this test method. Manufac-
turers MUST be consulted for specific
details such as material safety data sheets
and other manufacturer’s recommenda-
tions. All OSHA standards and rules
must also be consulted and followed.
4.1 Good laboratory practices should
be followed. Wear safety glasses in all
laboratory areas.
4.2 The 1993 AATCC Standard Refer-
ence Detergent may cause irritation. Care
should be taken to prevent exposure to
skin and eyes.
4.3 Manufacturer’s safety recommen-
dations should be followed when operat-
ing laboratory testing equipment.
5. Apparatus and Materials
5.1Automatic washing machine (see
12.1).
5.2Automatic tumble dryer (see 12.2).
5.3Conditioning/drying racks with
pullout screens or perforated shelves (see
12.3).
5.4Facilities for drip drying and line
drying.
5.51993 AATCC Standard Reference
Detergent (see 12.8 and 12.9).
5.6Ballast of 920 × 920 ± 30 mm (36
× 36 ± 1 in.) hemmed pieces of bleached
cotton sheeting (Wash load ballast type
1), or 50/50 polyester/cotton bleached
plain weave (Wash load ballast type 3)
(see 12.4 and 12.9).
5.7Indelible ink marking pen (see
12.5) for use with suitable rule, tape,
marking template or other marking de-
vice (see 12.6). Sewing thread may be
used for making benchmarks.
5.8Measuring devices.
5.8.1Tape or rule marked in millime-
ters, eighths or tenths of an inch.
5.8.2Tape or ruled template marked
directly in percent dimensional change to
0.5% or smaller (see 12.6).
5.9 Balance with at least 5.0 kg (10.0
lb) capacity.
6. Test Specimens
6.1 Sampling and Preparation.
6.1.1 Each garment will be considered
a specimen. Garments used as specimens
should be representative of the produc-
tion lot. When possible, three specimens
should be used. One or two specimens
may be used when insufficient garments
are available.
6.1.2 Garments that are distorted in
their unlaundered state due to faulty fab-
ric finishing, garment assembly, or pack-
ing may give deceptive dimensional
