Likewise, the static water droplet test is sufficient for aniline upholstery leather which is required to be resistant against spilled liquids. Leather which has absorbed too much . Unlike top-coated leather, aniline leather will absorb water and other liquids quickly, indicating its highly porous nature. A water drop test can help identify it - the water will darken the leather where it absorbs, .If getting to the back side of the leather is unattainable, a scratch test and a water drop test will usually answer the question. If you can easily leave a scratch on the surface of the leather with . AATCC TM22 is often used as a quick, low cost way to screen the water repellency of a fabric. This test method is applicable to any textile fabric, which may or may not have been given a water-repellent finish. It measures .

This test method is applicable to any textile fabric, which may or may not have been given a water-repellent finish. It measures the resistance of fabrics to .
In this work, the water absorption and transport properties of fabrics with different geometry and hydrophilicity were characterized by five conventional test methods and two recently developed water transport testers: Spontaneous Uptake Water Transport Tester (SUWTT) and Forced Flow Water Transport Tester (FFWTT). The aqueous liquid repellency test (also known as water rating method) describes a procedure where by 20 μL drops of solution with increasing concentration of isopropyl alcohol are introduced to the fabric and a rating number is assigned based on which strength of solution the fabric is able to successfully repel. Table 13.1 outlines which concentration of isopropyl alcohol . Strips of leather coated with various brands of leather finish. A drop of water is placed on each strip to test waterproofing. [logo size=”25px”]Observations:[/logo] Initially, the droplet of water remained on the surface for each strip. After blotting, the amount of water darkening on each strip was observed:
Perform the water drop test: This test helps you check the absorbency of the material. Real leather is porous and will absorb a small amount of water, while fake leather will not. Place a few drops of water on an inconspicuous area of the material. Real leather will darken as it absorbs the water, while fake leather will remain unchanged.Eurofins | BLC can test a finished product or sample to measure the resistance to water spotting on the leather: BS EN ISO 105-E07:2010 & BS EN ISO 15700:1999 - Spotting: water (water spotting) BS EN ISO 11642:2012 - Water (water fastness) BS EN ISO 105-E04:2013 & BS EN ISO 11641:2012 - Perspiration .
