In the textile industry, in order to ensure the ultimate quality, some equipment is usually used for inspection, such as whether it will be wear-resistant, etc., among which the prominent pilling problem. GESTER Instrument Equipment Co., Ltd. briefly introduces four kinds of textile pilling test normal method. Pilling box method: It is mostly used for balling test with wool fabric or wool-like fabric.Overview of the method: The sample is mounted on a cork cylinder liners and it is optionally turned in a wooden box with a constant rotational speed and cork lining. In the absence of agreement or regulation, it is recommended that the woolen fabric be turned 7200 rolls (i.e. 2 hours) and the worsted fabric inverted 14400 rolls (i.e. 4 hours). The test completes the visual description of fluffing and/or pilling performance. Instruments used: Pilling Box, ICI Pilling and Snagging Tester GT-C18 Random Tumble Method: Method Overview: Take three specimens from each laboratory unit. Take the specimens evenly spaced across the width of the laboratory sample or from three different panels in a garment. Specimens should be staggered in such a manner that no two specimens contain the same yarns. Avoid areas with wrinkles and other distortions. Using the random tumble-up pilling box was subjected to random tumble friction for 30 minutes in a cylindrical test chamber covered with a cork liner and filled with a small amount of grey short-lived cotton. The visual evaluation of the pilling performance was made under the specified light source conditions. Instrument used: Random Tumble Pilling Testing Equipment GT-C19A Compass track method: Method Overview: According to the prescribed method and test parameters, nylon brushes and fabric abrasives or only fabric abrasives are used to frictionally pill the specimens. Take a circular specimen with a diameter of 113mm and the test surface is mounted outward on the chuck. The grinding table is a test method of two materials. The fabric is rubbed with a nylon brush and tested with a standard fabric. After the test is completed, a visual description of the pilling performance is evaluated under the specified light source conditions.Instrument used: Surface Fuzzing and Pilling Tester GT-C16 Martindale Method: Method Overview: Under the specified pressure, the circular sample rubs against the same fabric or standard wool fabric abrasive with the path of the Lisa Ru graphic, and the sample can rotate freely around a central axis perpendicular to the sample plane. After the prescribed friction stage, ratings are visually described.Instrument used: Martindale Abrasion and Pilling Tester GT-C13B At present, there are four types of conventional pilling and snagging test methods for textiles.If you want to know more, get quotes and catalogues, please contact us：info@gester-instruments.com

The US Taber Abrasion Resistance Tester (ASTM D3884 Abrasion Resistance of Textile Fabrics ) is used to interpret the wear resistance of metals, coatings, plate surfaces, coating materials, textiles, leather, and rubber, etc. The first step, Calibrating wheels. A: Rubber-base Wheels Calibration (eg. CS-10, CS-10F, CS-17) (1) A new set of rubber-base wheels must be refaced twice for 50 cycles; (2) If the used wheel is less than 1000 cycles before use, refaced 25 cycles or 50 cycles (recommended refaced 25 cycles); if it is greater than or equal to 1000 cycles, pre-refaced 50 cycles. (3) For every 1000 cycles of the wheel during the test, 25 or 50 rotations must be refaced. B: Vitrified-based wheels Calibration ( eg. H-10, H-18, H-22, H-38) Not need to refacing unless the surface of the wheel is are marred or chipped; every 300 cycles, clean particles using an air hose durinf the test. Sampling: 150mm*150mm, 5 pieces (actual sampling 100cm²), for samples with width less than 125mm, the entire width for samples is used. The second part of the United States Taber Abrasion Tester, the specific operation: 1.Set the appropriate grinding wheel and load as required. Grind the fabric to a specific end point and record the final number of revolutions; the end point may include Pass/Fail criteria, such as: loss in breaking strength, yarn breakage, coating/gloss/gloss loss, appearance of pilling and other changes; if the customer Have their own requirements, according to customer requirements as the end. 2.Recording the number of sample rotations and take the average of 5 samples. End point judgment: Woven fabrics: break a single line Non-woven: Frayed at least 0.5mm in diameter Knitted fabric: 1 yarn broken, forming a hole Fleece: Flue finish references: 2007 and previous versions: Grinding wheel: CS-10 Load:> 240g/m2, 500g/rev ≤ 240g/m2, 250g/rev 2009 Edition According to use table ASTM D3884: Test of Friction Wheels and Heavy Hammer Loads, 2009 Edition Type of fabric Grinding wheel Load (g) Textile fabrics ≥100g/m2<240g/m2(medium) CS-10 500 Textile Fabrics <100g/m2 (Lightweight) CS-10 250 Fleece CS-10 500 Coated fabric H-18 1000 Automotive Fabric CS-10 1000 Decorative fabric H-18 500 Textile Fabrics (Other) H-18 1000 Non-woven fabric H-10 (Temporarily absent) 250 Automotive Leather CS-10 1000 Dyed Leather CS-10 500 Other durable leather H-18 1000 Car carpet CS-10 1000 Carpet (wide) H-18 500 US Taber Abrasion Tester Principle: An "X" type of friction is created by the rotation of a pair of friction wheels.

“Yellowing” refers to the surface of the white or light-colored substances become yellow under light, heat or chemicals impact. The yellowing phenomenon not only damage the appearance of the white, but also shorten it’s lift time greatly. White or light-colored textile made of nylon and elastic fibers as well as related combination fabric will become yellow easily. “Yellowing” will happens everywhere, such as the dyeing and finishing process, storing or hanging in the showcase or even at home. There’s many reasons which may cause “yellowing”, like the material itself may become yellow easily, or the chemicals used on the fabric (residual oil or softener)may become yellow easily too. Normally, we need to do further analysis if we want to know the real reason that the textile become yellow. Such as how to setting the processing conditions, which chemicals can be use or can not be use, which reasons may have coefficient effects on textile and how to packing and storing the textile. Reasons for fabric yellowing: （Gas fading）： ——Shaping machine NOx fumes ——NOx fumes during storage ——Exposure to ozone （Temperature）： ——Heat Sizing ——High temperature die-cast ——Softeners and high temperature processing （Packaging&Storage）： ——Phenol and amine related yellowing sunlight ——  Dye and Fluorescent Fading ——  Fiber degradation （Micro-organisms）： ——  Suffered from the destruction of bacteria and mold （Miscellaneous）： —— The relationship between softener and fluorescein Source analysis of the problem or countermeasures: Setting Machine There are many setting machines can be applied in textile industry. Such as heat by burning gas or oil directly. Machines heating by this way may product NOx which is harmful. In order to avoid surplus NOx when sizing the the specimen. We can use GESTER Laboratory HT Steamer Stender-Vertical Type GT-D21B when specimen sizing. Ozone fading This may usually happens in apparel industry. Some softener may make the textile yellowing because of the Ozone. Special ozone resistance softener may reduce this problem.We can use GESTER Colorfastness to Ozone GT-D01B to imitate the Ozone environment. High Temperature Textile will become yellow because fiber oxadate,  lubricant on the fiber and textile or impurity on the fiber effected by high temperature. And this may cause during the stamping procedure of synthetic fabrics (especially girs’underwear like PA/EL bra) .GESTER GT-C52 Programmable Temperature & Humidity Test Chamber can help you when having the test. Sunlight Generally speaking, the light fastness of fluorescent brightener is poor. Fabrics with fluorescent brightener may become yellow easily if exposure under the sunshine for a long time. So we suggest to use high light fastnees fluorescent brightener if the fabrics is strict on quality. Sunlight, as a kind of energy, will let the fiber regression. Glass can’t filter out all the UV (can only filter light wave lower than 320nm). Nylon is easy to beco...
