AATCC 86:2016 pdf download.Drycleaning: Durability of Applied Designs and Finishes
1. Purpose and Scope
1.1 This lest method indicates the effect of repeated (see 10.1) drycleanings on the durability of applied-design or finish on textiles and other materials. It is also applicable for evaluating the durability of applied design materials and finishing agents manufactured for use on fabrics and other products intended for apparel and household use which are renovated in consumer service by commercial drycleaning procedures. This test meth(xi is to he used for evaluating the resistance of colors to spot and stain removal procedures used by the drycleaner.
1.2 This test method is not intended for evaluating colorfastness to drycleaning.For colorfastness properties use AATCC Test Method (TM) 132, Colorfastness to Drycleaning.
2. Principle
2.1 A specimen is agitated in a solution of solvent and a drycleaning detergent with steel halls 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 petroleum solvent, perchloroethylene or 11 UOrOCarhOfl.
NOTE: The process also includes adding 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 procedures 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.
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 vapors 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 perchioroethylene.
4.4 An eyewash/safety shower should he located nearby and an organic vapor respirator should be readily available for emergency use.AATCC 86 pdf download.
