(Test Method)Standard Test Methods for Bonded, Fused, and Laminated Apparel Fabrics
Standard Test Methods for Bonded, Fused, and Laminated Apparel Fabrics
SIGNIFICANCE AND USE
5.1 These test methods for the determination of properties of bonded, fused, or laminated apparel fabrics, are considered satisfactory for acceptance testing of commercial shipments of bonded and laminated apparel fabrics since the methods have been used extensively in the trade for acceptance testing.
5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use the samples for such a comparative test that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing. Randomly assign specimens in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data and a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.
SCOPE
1.1 These test methods cover procedures for characterizing the delamination, strength of bond, appearance, and shrinkage propensity of bonded, fused, and laminated apparel fabrics after drycleaning and laundering.
1.2 The values stated in SI units are to be regarded as standard; the values in parentheses are provided as information only.
1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative
tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a
minimum, use the samples for such a comparative test that are as homogeneous as possible, drawn from the same lot of material
as the samples that resulted in disparate results during initial testing. Randomly assign specimens in equal numbers to each
laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data and a
probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results
for that material must be adjusted in consideration of the known bias.
6. Apparatus and Materials
6.1 Drycleaning Machine, single-unit, coin-operated type, capable of providing a complete automatic dry-to-dry cycle using
perchlorethylene. It shall consist of a commercial rotating cage type, totally enclosed machine. The diameter of the rotating cage
shall be not less than 600 mm (24 in.) and not more than 1080 mm (42 in.). Its depth shall be not less than 300 mm (12 in.). It
shall be fitted with two to four lifters. The speed shall be such as to give a g-factor between 0.5 and 0.9 for cleaning and between
35 and 120 for extraction. The machine shall be equipped with thermometers for the measurement of the solvent temperature and
the air drying temperature.
NOTE 1—The g-factor is calculated using Eq 1 or Eq 2:
g 5 1.42n D/100 000 (1)
g 5 5.59n d/10 000 000 (2)
where:
n = revolutions per minute,
D = cage diameter, in., and
d = cage diameter, mm.
6.2 Domestic Automatic Washer, top-loading, spin-extracting type.
6.3 Domestic Automatic Tumble Dryer, front-loading type.
6.4 Aspirated Psychrometer, which meets the requirements of Test Method E337.
6.5 Marking Device —A thin sheet of stainless steel or other rigid flat material in which a square opening 254 by 254 mm (10
by 10 in.) has been cut.
6.6 Rule, 305-mm (12-in.) or longer, preferably divided into tenths of an inch. A premarked device calibrated to give the
percentage of shrinkage or growth may also be used.
6.7 Sewing Machine, suitable for sewing a single row of stitching, preferably with No. 00 mercerized cotton thread, 25 mm (1
in.) from the edge of the fabric specimen.
6.8 Steam Iron, hand type.
6.9 Steam Press, a press, 600 by 1250 mm (24 by 50 in.), or larger, provided with 60 to 70 psig steam pressure at the press.
Any steam press large enough for pressing a specimen 380 mm (15 in.) square may be used.
6.10 Tensile Testing Machine, conforming to Specification D76, either a constant rate of traverse type or a constant rate of
extension type, equipped with clamps having a width of 76.2 mm (3.00 in.) and preferably calibrated in kilograms with a range
from 0 to 4.5 kg (0 to 160 oz). The constant rate of extension type machine is preferred because of the inherently lower
machine-induced errors in this type of machine.
6.11 Detergent, home laundry type.
6.12 Perchlorethylene, commercial grade.
NOTE 2—Warning: Perchlorethylene is toxic, and the usual precautions for handling chlorinated solvents should be taken. It should be used only under
well-ventilated conditions. The solvent is nonflammable.

7. Sampling
7.1 Lot Sample—As a lot sample for acceptance testing, take at random the number of rolls of fabric directed in an applicable
material specification or other agreement between the purchaser and the supplier. Consider rolls of fabric to be the primary
sampling units.
NOTE 3—An adequate specification or other agreement between the purchaser and the supplier requires taking into account the variability between rolls

D2724 − 07 (2015)
of fabric and between specimens from a swatch from a roll of fabric so as to provide a sampling plan with a meaningful producer’s risk, consumer’s risk,
acceptable quality level, and limiting quality level.
7.2 Laboratory Sample—As a laboratory sample for acceptance testing, take a full width swatch 1 m (1 yd) long from the end
of each roll of fabric in the lot sample, after first discarding a minimum of 1 m (1 yd) of fabric from the very outside of the roll.
7.3 Test Specimens—Proceed as follows:
7.3.1 Drycleaning and Laundering—Cut four specimens from each swatch in the laboratory sample with each specimen being
380 by 380 mm (15 by 15 in.) in size, with the one side of the specimens from a single swatch parallel to the selvage. Locate two
of the specimens from each swatch about ⁄3 of the distance from one selvage and locate the other two specimens from each swatch
about ⁄3 of the distance from the other selvage. Locate each of the two specimens from one side of the swatch along a diagonal
line on the swatch so that they will contain different warp ends and filling picks. Sew a straight line of stitching around each
specimen 25 mm (1 in.) from each edge. Reserve the rest of the swatch for comparison with the drycleaned and laundered test
specimens.
7.3.2 Strength of Bond—Prepare three test specimens, each measuring 76 mm (3 in.) wide, and 152 mm (6 in.) long, the length
of the specimens corresponding to the lengthwise direction of the fabric. Do not take the test specimens closer to the selvage than
a distance equal to 20 % of the fabric width.
NOTE 4—Samples that are 51 mm (2 in.) wide may be used as the minimum width.
8. Conditioning
8.1 Bring the samples from the prevailing atmosphere and condition them for at least 4 h in the standard atmosphere for testing
textiles as directed in Practice D1776 if shrinkage is to be determined. Preconditioning is not necessary.
9. Specimen Preparation
9.1 Using an indelible fineline marker, mark a 254 by 254 mm (10 by 10 in.) reference square centrally located on the face of
each test specimen. Apply three sets of reference markings 254 6 2 mm (10 6 0.1 in.) apart, as measured with a rule, in the
direction of the fabric length. Locate the markings within 25 mm (1 in.) of each end and at the midpoint of each side of the square.
Similarly, apply three sets of markings in the direction of the fabric width. Any other method of accurately locating the 254-mm
(10-in.) reference marks is satisfactory as long as the three marks on each side of the square are at least 105 mm (4 in.) apart.
10. Drycleaning Procedure
NOTE 5—Launderable fabrics are expected normally to be drycleanable, except where the face fabric is not drycleanable and is so labeled. For example,
the fabric could contain a functional finish soluble in the solvent, or the fiber could be degraded by the solvent, which would be the case with poly(vinyl
chloride) fiber.
10.1 Solvent Preparation—Prepare a standard detergent/drycleaning solvent mixture by adding sufficient detergent to the
solvent to make a 1 % volume/volume solution. Add sufficient water to the solution to give a solvent relative humidity level of
75 % for the particular drycleaning detergent used. Put this solvent in the machine storage tank. The same solution can be used
for repeated cleanings until it becomes dirty and needs replacing as long as the necessary water additions to maintain the solvent
relative humidity constant are made prior to each test run. This is so because the specimens being run could conceivably alter the
solvent relative humidity for succeeding test runs while the detergent level would remain constant.
10.2 Sample and Dummy Load Preparation— Prepare a load consisting of all specimens to be tested and made up to 3.6 kg (8
lb) total with dummy load of approximately 380 by 380-mm (15 by 15-in.) fabric pieces of similar material. Condition this load
at least 4 h in the standard atmosphere for testing textiles. After the drycleaning operation, condition the load again before running
through each additional drycleaning cycle. Conditioning before each drycleaning cycle is intended to minimize depletion of water
from the drycleaning solution specified in 10.1.1 which may affect shrinkage results.
10.3 Drycleaning Procedure—Run through the complete dry-to-dry cycle in the machine. Run the solvent phase of the
drycleaning cycle with the solvent no higher than 32°C (90°F). During the drying phase of the drycleaning cycle, either the air
outlet temperature should not exceed 60°C (140°F) or the inlet air temperature should not exceed 80°C (175°F). If heat-sensitive
fibers, for example, modacrylic fibers, are involved, the outlet air temperature should not exceed 40°C (105°F) or the inlet air
temperature should not exceed 60°C (140°F). After the complete drycleaning cycle, remove the sample from machine for
examination and reconditioning.
10.4 Repeat the drycleaning operation through two additional cycles. At the end of the third cycle remove the test specimens
from the machine, lay on a flat surface, smooth the test specimens by hand, and examine. Press the test specimens using the steam
press according to the following cycle:
