AATCC 88c-2006 Retention of Creases in Fabrics after Repeated Home Laundering.
4. Satety Precautions
NOTE: These safety precautions are for information purposes only. The precautions are ancillary to the testing proce- dures and are not intended to be all inclusive. It is the user’s responsibility to use safe and proper techniques in handling materials in this test method. Manufacturers MUST be consulted for specifie details such as material safety data sheets nd other manufacturer’s recommenda- tions. All OSHA standards and rules must also be consulted and followed.
4.1 Good laboratory pactices should be followed. Wear safety glasses in all labonatory areas.
4.2 The 1993 AATCC Standard Reference Detergent and the 2003 AATCC Sundard Reference Liquid Detergent may cause imiation. Care should be taken to prevent exposure to skin and eyes.
4.3 All chemicals should be handled with care.
4.4 Manufacturer’s safety recommendutions should be followed when operating laboralory testing cquipment.
4.5 When evaluating crease retention, use of a lamp with a shield can aid in pre- vention of burns that could result from lamp heat.
5. Uses and Limilations
5.1 This test method is designed to be used only. for evaluating the appearunce of washable creased fabrics after repeated home laundering.
5.2 The test procedure is designed to reflect the capabilities of home laundry equipment which is currenly used by consumers. In general, it is preferable to conduct the test under relatively severe laundering conditions.
5.3 Prints and patterms may mask the appearance of a crease. The rating process is, however, based on the visual a4p- pearance of specimens including such ef fects.
5.4 The small specimen sizes used for fabric tests occasionally will cause wrinkles or creases (dryer creases) to develop which are not considered to be characteristic of fabric performance in use. Precautions are given in the text of the method to reduce the occurrence of dryer crcases.
5.5 The interlaboratory reproducibility of the rtsults of this test method depends upon mutual agreement by users of the method on the washing and drying condi- tions as oulined in 8.1.
6. Apparatus and Materials
6.1 Automatic washing machine (sce 12.1).
6.2 Automatic tumble dryer (see 12.1).
6.3 Drip dry and line dry facilities.
6.4A 9.5 L (10.0 q0) pail.
6.5 1993 AATCC Standard Reference Detergent or 2003 AATCC Sandard Ref. erence Liquid Detcrgent (scc 12.2 and 12.8).
6.6 Ballast of92x92 +3 cm (36x 36 士1 in.) hemmed pieces of bleached colton sheeting (Wash load ballast type 1)or 50/50 polyesterlcotton plain weave (Wash load ballast type 3) (see 12.3).
6.7 Lighting and evaluation area in an otherwise darkened room using the overhead lighting arrangement shown in Fig. 1 (see 12.4). It has been the experience of many observers that light reflected from the side walls near the viewing board can interfere with the rating results. It is recommended that the side walls be painted matte black (850 gloss less than 5 units) or that blackout curtains be mounted on both sides of the viewing board to elimi- nate the reflective interference.AATCC 88c pdf download.
