AATCC 207-2017 pdf free.Seam Twist in Garments Before and After Home Laundering.
Deiennine the seam(s) to evaluate for twist (sec 5.1). Evaluation of all scam types is recommended to get a complete picture of garment appearance.
After conditioning. lay one test specimen on a flat surface in its natural configuration. so the first seam to be measured is visible (if the seam has twisted to the back of the specimen, lay the specimen face down), It may be helpful to gently shake the specimen to allow it to hang loosely. hut do not stretch or distort the specimen in shaking. Smooth. but do not stretch, all panck. including seams and hems,
Mark Point A at the lower edge of the seam, including hem. Mark Point B 25 mm (I in.) below the point at which the scam intersects another seam. For example. mark Point II of pant inseam 25 mm below intersection with risc scam:mark Point H of shirt side seam 25 mm below intersection with armhole (see Figs. I and 2).
Measure and record seam length AB to the nearest millimeter. or eighth or tenth of an inch.
Determine if seam twist exists before laundering.
If the seam falls along the natural fold of the garment, there is no seam twist (see Figs. I and 2). Record original twist distance as (1 mm or 0.0 in.
If the seam does not fall along the natural tbld of’ the garment, mark Point A’ at the lower edge of the natural fold, including hem (see Figs. 3 and 4).
Measure and record original twist distance AA’ for each scam to the nearest millimeter. or eighth or tenth of an inch.
Repeat 9.2 through 9.5 for remaining seams on all specimens.
Traditional top-loading washing machines,
Select laundering instructions based on miended care label for garmeni Refer to temperatures and machine specifications in Monograph M) 6. Standarditation of Home Laundiy Test Conditions. Tables I and IIA.D (see 14.4). If alternate wash temperatures or machine specifications are used, note modifications in the test report.
Wash load shall consist of all specimens in the sample, plus enough ballast pieces to make a total load weight of 1.8 0.1 kg (4.00±0.25 lb) or 3.6 0.1 kg (8.00 0.25 1lb). 10.1.3 Begin selected wash cycle. During initial fill, add 66 1 g of 1993 AATCC Standard Reference Detergent as directed by washing machine manufacturer ‘s instructions. If detergent is added directly to wash water, mix to dissolve completely before adding wash load.
Add wash load (test specimens and ballast), distributing evenly around center agitator.
For specimens to be drip dried, stop wash cycle before the water begins to drain from the final rinse cycle. Remove specimens soaking wet. For spedmens to be tumble, line, or screen (flat) dried, allow washing to proceed through the final spin cycle.
After each washing cycle, separate tangled specimens and ballast pieces, taking care to minimize distortion. Proceed to appropriate drying procedure.
High-efficiency (HE) washing machines.
For HE top-loading washing machines, refer to temperatures and machine specifications in M6, Tables 111 and IV; for front-loading washing machines, refer to M6, Tables V and VIA-B (see
14.4). If alternate wash temperatures or machine specifications are used, note modifications in the test report.
Wash load shall consist of all specimens in the sample. plus enough ballast pieces to make a total load weight of 1.8±0.1 kg(4.O0±O.25 Ib).
After each washing cycle, separate tangled specimens and ballast pieces,taking care to minimize distortion. Proceed to appropriate drying procedure.
Hand laundering.
For hand laundering, refer to procedure in M5， Standardization of Hand Laundering for Fabrics and Apparel (see 14.3).
After each washing cycle, proceed to appropriate drying procedure,taking care to minimize distortion.
Tumble dry.Refer to tumble dryer exhaust temperatures in M6, Table VII.
Place the washed load (test specimens and ballast) in the tumble dryer. and set the temperature control to generate the selected exhaust temperature.
Allow the dryer to run until the load is fully dry. Remove specimens immediately.
Hang each specimen on an appropriate hanger. straightening and smoothing facings, seams. etc. Specimens should generally be oriented in the direction in which they are worn. Do not fold or stretch specimens over the hanger.
Allow specimens to hang in still air at room temperature not greater than 26°C (78°F) until dry. Do not blow air directly on specimens as it may cause distortion.
Hang dripping wet specimen on an appropriate hanger, straightening and smoothing facings, seams, etc. Specimens should generally be oriented in the direction in which they are worn. Do not fold or stretch specimens over the hanger.
Allow specimens to hang in still air at room temperature not greater than 26°C (78°F) until dry. Do not blow air directly on specimens as it may cause distortion.
Spread each specimen on a horizontal screen or perforated surface, removing wrinkles without distorting or stretching it.
Allow specimens to stand in still air at room temperature not greater than 26°C (78°F) until dry. Do not blow air directly on specimens as it may cause distortion.
Point A” at the lower edge of the natural fold (see Figs. 3 and 4).
Measure and record after-laundering twist distance AA” for each seam to
the nearest millimeter, or eighth or tenth of an inch.
