Purpose of Test The accelerated laundering test evaluates how a textile loses its coloring under expected washing conditions. The textile’s colors are expected to resist frequent washing and you want to be sure it can before it is sent to market. This test uses a washing machine set at 49°C. The test lasts for about… Continue reading AATCC 61 2A Colorfastness to Laundering: Accelerated (Machine Washing at 49°C)

AATCC 61 Colorfastness to Laundering: Accelerated
Purpose of Test The accelerated laundering test evaluates how textile’s color will fade under given laundering circumstances. This test will provide a measurement of the colorfastness of textile to laundering, which is expected to resist frequent washing. The test roughly lasts for 45 minutes but is designed to estimate performance over the life of a… Continue reading AATCC 61 Colorfastness to Laundering: Accelerated
AATCC 147 Antibacterial Activity of Textile Materials: Parallel Streak
Purpose of Test This test method assesses the ability of a textile to prevent growth of microorganisms. This evaluation estimates the antibacterial efficacy against various concentrations of microorganisms. The parallel streak method is performed to qualitatively evaluate the bacteriostatic activity of diffusible antibacterial agents on treated textiles. Through the years, this test has been used… Continue reading AATCC 147 Antibacterial Activity of Textile Materials: Parallel Streak
AATCC 22 Water Repellency: Spray Test
Purpose of Test The water repellency spray test evaluates a fabric’s resistance to getting wet with water. This test is primarily used for textile fabrics that may or may not have been treated with a water-repellent finish. This test is ideal for assessing water resistance of various fabric finishes. The test results for this method… Continue reading AATCC 22 Water Repellency: Spray Test
AATCC 127 Test Method for Water Resistance: Hydrostatic Pressure
Purpose of Test This test evaluates the resistance of a fabric to water penetration caused by hydrostatic pressure. This test is used for all kinds of fabrics, whether they are water-resistant or water-repellant. The test results for this method depend on the water repellency of the following materials used: Fibers Yarns Fabric construction Fabric finish… Continue reading AATCC 127 Test Method for Water Resistance: Hydrostatic Pressure
AATCC 42 Test Method for Water Resistance: Impact Penetration
Purpose of Test This test checks for fabric resistance against water penetration by impact. It is applicable to any kind of textile fabric that may or may not have been treated with water-resistant or water-repellant finishes. The test may also be used to assess the probable resistance of rain against fabrics. The test results for… Continue reading AATCC 42 Test Method for Water Resistance: Impact Penetration
ATCC 100 Test Method for Antibacterial Finishes on Textile Materials: Assess
Purpose of Test The test method aims to quantify the antibacterial properties of textile materials. This test method is designed to evaluate various types of textiles by performing a 24-hour contact assessment of the bacteriostatic (growth inhibition) and bactericidal (bacteria elimination) properties. Terminology Defined Antibacterial Activity – Measures the protection a textile provides against microorganisms,… Continue reading ATCC 100 Test Method for Antibacterial Finishes on Textile Materials: Assess
AATCC 94-2017 Formaldehyde (Spot Test)
Purpose of test This test is used to determine the amount of formaldehyde released by various textiles.. These can include: Yarns Fibers Other fabrics Terminology Defined Chromotropic acid — A chemical that reacts with formaldehyde and sulfuric acid and causes a test specimen to display color when formaldehyde is present. Test method Materials Used for… Continue reading AATCC 94-2017 Formaldehyde (Spot Test)
AATCC 112 Formaldehyde Release from Fabric (Quantitative) – Sealed Jar Method
Purpose of test This test uses fabric and water in a sealed jar to measure how much formaldehyde the specimen will release over time. Terminology Defined Colormetrics — Determining the nature and amount of a substance within water by the intensity of any color produced. Test method Materials Used for Test Fabric specimen Clear glass… Continue reading AATCC 112 Formaldehyde Release from Fabric (Quantitative) – Sealed Jar Method
AATCC 162 Colorfastness to Chlorinated (Pool) Water
Purpose of test This test shows how well colored fabric or yarn holds its color when exposed to chlorinated water. The method was designed for textiles made from various fibers and with various coloring types: Printed Dyed Yarn Other Coloring Techniques Terminology Defined Colorfastness — A fabric’s ability to retain color in various conditions. Gray… Continue reading AATCC 162 Colorfastness to Chlorinated (Pool) Water
