Purpose of Test This test is a qualitative analysis describing the chemical, microscopical, and physical techniques for the identification of commercial textile fibers. It is used in accordance with the Textile Fibers Products Identification Act. The textile fibers can be examined in these forms: Raw Taken from yarn Taken from fabric Terminology Defined Fiber Analysis… Continue reading AATCC 20 Test Method for Fiber Analysis: Qualitative

Purpose of Test The heated plate method evaluates the drying rate of fabric based on the evaporative rate that happens when a fabric absorbs a given amount of water and is placed on a heated plate set at 37°C and air-dried at a controlled flow.  The temperature used is equivalent to human skin temperature when… Continue reading AATCC 201 Drying Rate of Fabrics: Heated Plate Method

Purpose of Test This test evaluates the pH levels of wet-processed textiles. In this test, the chemicals affecting pH are removed from the textile and collected as water extract to measure the pH level. Terminology Defined pH –  Measurement of how acidic or basic a liquid is. Wet Processing – The manufacturing stage of textile… Continue reading AATCC 81 pH of the Water-Extract from Wet Processed Textiles

Purpose of Test The AATCC 30 test method evaluates and compares the antifungal activity of textile materials like gauze, cloth, and similar objects. This test method has two purposes: Determine textile’s susceptibility to mildew and rot. Measure the effectiveness of fungicides on textile materials. Terminology Defined Antifungal Activity –  Evaluates the textile property to protect… Continue reading AATCC 30 Antifungal Activity, Assessment on Textile Materials: Mildew and Rot Resistance of Textile Materials

Purpose of Test This test evaluates the ultraviolet radiation (UV-R)  blocked by textile fabrics treated with UV protection. This test simulates the UV-R on various fabrics to make sure they are properly rated for UV protection. It provides a general procedure for determining UV protection property in textiles in these conditions: Wet Dry Terminology Defined… Continue reading AATCC 183 Transmittance or Blocking of UV Radiation through Fabric

Purpose of Test This colorfastness to light test is designed to determine how well a material will retain its color under various light exposures. The test provides the principles and procedures that make it possible to evaluate colorfastness under different conditions. This test method was designed for textiles made with various kinds of colorants, treatments,… Continue reading AATCC 16 Colorfastness to Light

Purpose of Test This test evaluates fabric resistance against water penetration by impact. It is applicable to any textile fabric that may or may not have been treated with water-resistant or water-repellant finishes. The test is used to assess the probable resistance of rain against fabrics. The test results for this method depend on the… Continue reading AATCC 35 Test Method for Water Resistance: Rain

Purpose of Test This test evaluates the water absorbency of fabrics, yarns, and garments. This test is used for textiles of any fiber content or construction, which include fabrics like: Woven Knit Nonwoven Terminology Defined Water Absorbency – The measurement of how much water is absorbed by the textile when wetted with water. Wetting –… Continue reading AATCC 79 Absorbency of Textiles

Purpose of Test The colorfastness to crocking test method measures color transfer of a colored textile to other surfaces by rubbing. This test method is used for textiles made from various fibers and with various coloring types: Yarn Other Fabrics Dyed Printed Other Coloring Techniques Terminology Defined Colorfastness – Colorfastness is a fabric’s ability to… Continue reading AATCC 8 Colorfastness to Crocking: Crockmeter
