AATCC 86-2016 Drycleaning: Durability of Applied Designs and Finishes

AATCC 86-2016 Drycleaning: Durability of Applied Designs and Finishes. 2.1 A specimen is agitated in a solution of solvent and a drycleaning detergent with steel balls to simulate the kind of mechanical action that occurs in a dry- cleaning machine. A large specimen is provided to produce a correlation with commercial conditions. 3. Terminology 3.1 drycleaning, n.—the cleaning of fabrics with organic solvents such as pe- troleum solvent, perchloroethylene or fluorocarbon. NOTE: The process also includes add- ing detergent and moisture to the solvent, up to 75% relative humidity, and hot tumble drying to 71°C (160°F). 4. Safety 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 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 recommendations. All OSHA standards and rules must be consulted and followed. 4.1 Good laboratory practices should be followed. Wear safety glasses in all laboratory areas. 4.2 All chemicals should be handled with care. 4.3 Perchloroethylene is toxic by inhalation, by repeated contact with the skin and by ingestion. It should be used only in a well vented atmosphere. Toxicology studies with laboratory animals have shown evidence of cancer in rats and mice exposed to perchloroethylene va- pors at 100-400 ppm concentrations for prolonged times. Fabric saturated with this solvent should be dried in an adequately ventilated hood. Use chemical goggles or face shield, impervious gloves and an impervious apron when handling perchloroethylene. 4.4 An eyewash/safety shower should be located nearby and an organic vapor respirator should be readily available for emergency use. 4.5 Exposure to chemicals used in this procedure must be controlled at or below levels set by governmental authorities (e.g., Occupational Safety and Health Administration’s [OSHA] permissible exposure limits [PEL] as found in 29 CFR 1910.1000; see web site: www.osha.gov for latest version). In addition, the American Conference of Gov- ernmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLVs) com- prised of time weighted averages (TLV- TWA), short term exposure limits (TLV- STEL) and ceiling limits (TLV-C) are recommended as a general guide for air contaminant exposure which should be met (see 10.2).AATCC 86 pdf download.
