In daily life, people would find that the sole and upper of newly white shoes would become yellowing. Do you know why it would yellowing? That’s because the phenomenon of color yellowing of footwear materials like PU polyurethane, UV-free antioxidant TPR thermoplastic rubber, and leather coated with polymer materials are likely to occur under exposuring to sunlight, ultraviolet light for a long time or in the heat, oxygen, stress, trace moisture, improper processing. Reducing and prolonging the yellowing time has always been an urgent problem to be solved. Many shoe-making enterprises refer to HG/T 3689-2014 "Shoes for yellowing resistance test method" to determine the yellowing resistance of finished shoes and footwear materials. And the test of yellowing resistance has also become an important test for the quality management of the footwear industry. What can we do in daily life to delay the yellowing of light-colored shoes? The following methods are for reference only, and take care that do not to expose the shoes to the sun or to expose them to high temperatures. A.Maintenance during washing It is best to choose neutral detergent (soap with a pH value between 6 and 8, liquid detergent, etc.), do not choose ordinary alkaline detergent. White shoes are better avoided being washed with water, and handled in time when shoes are a little dirty, so as to clean them up and prevent damage to the upper caused by long-term stains. When drying after washing, better to use paper towel to wrap, it can prevent white shoes to become yellow and even let white shoes go back to the original color. Do not exposed to the sun. Ultraviolet light is the main cause of rapid yellowing. B.Collection maintenance The white shoe that does not wear temporarily, better clean thoroughly before collect, prevent dirty mark to remain for a long time to produce mildew possibility. When collecting, choose dry place to store, better to put away in originally shoe box. In order to protect the shape of the white shoes, it can also be inserted into the shoe last or the old newspaper to fix, it will be taken out as new. A little desiccant can be put into the shoe box to anti-worms and keep dry. Choose the shoes which are hard to discolor will let white shoes to maintain the beautiful white color all the time.  How to know if a pair of shoes will turn yellow in a short time? Please choose GESTER GT-KD02 UV Light Discoloration Tester to test for you.

Everyone is familiar with clothes pilling, believe that many people have met clothing pilling after wearing a period of time. Pilling is one of the important factors which affect the feeling, appearance and wear performance of the fabric. So where does it come from? What kind of cloth will get pilling easily? How does the laboratory test and evaluate the pilling performance of clothing? Where does it come from? The fabric being constantly friction while using, so that the surface fiber ends been pulled by dragged, hooked and pulled out, and the phenomenon of forming hairiness on the fabric surface was called fluffing. As the hairiness is gradually extracted and extended, generally more than 5mm, and then bearing the friction, these fiber ends will hook each other, winding to form an irregular spherical phenomenon known as pilling. As the fabric continues to rub, the fiber balls gradually become closer and the fibers attached to the fabric are subjected to repeated bending, fatigue and even fracture in different directions. The fiber balls then fall off the fabric surface, but the fiber hairs at the end of the fracture will continue to be pulled out in use and form the fiber balls again. Why does it pill? The continuous mechanical action such as friction and hook during the wearing or washing of clothes causes the pilling of clothes. What kind of cloth will get pilling easily? Wool and its blended fabric: knitted sweater class, woollen sweater class, wool sweater. Chemical staple fiber and its blended fabric: polyester cotton, polyester viscose, nitrile cotton, etc. The knitting category of light fabric: pure cotton rack, mordale, viscose, tiansi and other recycled cellulose fiber fabrics. Embroidered cowboy. How does laboratory test pilling performance? Principle and instrument: Surface Fuzzing and Pilling Tester The sample is rubbed with nylon brush and fabric abrasive or only with fabric abrasive on a specified number of times under specified pressure to make the surface of the sample pilling. The method is fast and can simulate the tripping and pilling of the fabric. It is suitable for the knitted fabric such as garment and T-shirt. Martindale Abrasion and Pilling Tester Under specified pressure, the circular sample rotates freely around the center axis perpendicular to the plane of the sample, and the trajectory of the lizaru figure is rubbed with the same fabric or wool fabric abrasive. Suitable for bed category testing. ICI Pilling and Snagging Tester The sample installed on the polyurethane tube is flipped randomly in a wooden box with constant rotation speed and lined with cork. After a specified number of turns, the pilling and/or pilling performance is evaluated visually. Applicable to the testing of sweater - like textiles. Random Tumble Pilling Tester     Random rolling pilling is used to make the fabric tumble and rub randomly in a cylindrical test chamber lined with cork gaskets and a small am...

“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...
