“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...

Color fastness is a type of color fastness, also known as color fastness or color fastness to bleed, which refers to the migration of dye or residual floating color on the fabric, mainly reflecting the fabric after washing or being exposed to rain. The degree of contamination that causes dyes to elute at dyeing sites and shift to white or light-colored base fabrics comes from Japan. It is also called the "big pill method" in the Japanese test method. Color weeping fastness has now become one of the common testing items for Japanese singles. Generally speaking, it is required to reach level 4 or above 4-5, which is mainly manifested in medium and dark colors. It is often associated with color fastness. Good color fastness and good weeping fastness will also be good. The improved color fastness of cotton fabrics can be improved and strengthened from the following major aspects: 1.choose the right dye Because the dyes are often accompanied by a small amount of incomplete dyes in the synthesis, the presence of these dyes will not only affect the color fastness but also affect the other color fastness. Therefore, the color fastness test should be done before use. At the same time, attention should be paid to the use of reactive dyes in which the water-soluble groups in the dye structure are not too high and the directness is intermediate. 2.Pay attention to the impact of water quality The calcium and magnesium ions in the water will form insoluble matter with the dye and adsorb on the surface of the fiber, becoming floating color and hindering the diffusion and penetration of the dye, reducing the color fastness and even affecting the shade and vividness. Therefore, soft water or chelating dispersant must be added. Wait. 3.to strengthen the washing and soaping process The residual alkali salts on the fibers, hydrolysis, and the floating color of the unbound dyes are the key factors affecting the fastness, and high-performance anti-soap soaping agents with excellent properties should be selected, and soaps should be soaped under neutral or weak acid as much as possible. Higher temperatures are used to wash off unbound dyestuffs inside the fabric, but it is also important to note that too high a temperature can cause breakage of bonded dyes, especially under alkaline conditions. 4.using solid color processing The use of excellent cations and reactive fixatives can block the water-soluble groups of the dyes, making the dyes insoluble in the lake and depositing in the fibers, reducing the water solubility of the dyes, while a small amount of hydrolyzed dyes can also participate in the fixation. Cross-linking further increases the binding force with the fiber, thereby effectively improving the wet processing of the dye, the fastness of the color cry, etc., and if necessary, individual deep color shades can also be subjected to a re-fixation process. Of course, in addition to paying attention to the above points, whether the quality of the grey cloth itself...

We were appreciated to be invited again to participate SIMAC Tanning & Tech 2018, the international event with the most qualified offer of machinery and technologies for the footwear, leather goods and tanning industries, which takes place in Milan, concurrently with Lineapelle.

According to the latest regulations issued by the US Consumer Product Safety Commission (CPSC), the new US toy safety standard ASTMF963-17 came into effect on February 28, 2018. This action of the United States will make toy manufacturers face more stringent market access threshold. ASTM has become one of the highest accredited certification standards in the United States. The standard stipulates technical requirements and test methods for toys used by children under 14 years of age and has a wide range of international influence, toys that do not meet ASTMF963 standards will not be able to enter the US market. With the economic development and the improvement of the people's consumption level, everyone's requirements for the quality of toys are also getting higher and higher. Toy companies should continue to improve their product quality to meet consumer demand. For more risky toy products, companies should provide eye-catching instructions and warning signs to remind consumers to strengthen child custody and reduce security risks. GESTER is a professional toy safety testing equipment company, with nearly 20 years of research and development experience, we provide professional toy testing equipment to help companies monitor the quality.

The color and color of the dyed products are different,and there are two symptoms( in this problem): One is batch chromatic aberration:In the same batch, there is a color difference between the case and the case, between the parts, between the bag and the bag, and between the piece and the piece. The other also is batch chromatic aberration(but there's a difference):In the same batch of products, there is a color difference in the left or in the front and back, or in the front and back. The fiber composition of all kinds of fabrics is different, the kinds of dyes and the process equipment used in dyeing are different, and there are different requirements and characteristics in dyeing and processing. The causes and manifestations of defects are different. Color aberration is varied in appearance, but the main reasons are as follows: First is uneven distribution of dyes on fabric(including fabric factor,absorbent factor,pre-drying factor); Second is dyestuffs have a different degree of fixation on the fabric;Last is dye color variation(including predyed factors,dyeing factor,post-dye factors and soaping.) The product has color difference that bring the bad shopping experience for consumer and the bad influence for brand public praise.Due to reduce this negative effect for minimum level,we should launch a strict test about color difference when the product is finished. GESTER is just for professional testing,there are some testing machine from us will introduce for you to improve the color difference and the quality of product.as below: 1、Electronic AATCC Rotary Vertical Crockmeter GT-D45B 2、Lab winch yarn dyeing machine GT-D26 3、Room Temperature Dyeing Machine GT-D16 4、Laboratory Dyeing Padder GT-D19B  

The colour fastness of textile is meaning the fading degree of dyed or printed fabric that undergo the effect of external factors (including extrusion, friction, washing, rain shower, exposure, light, seawater impregnation, saliva impregnation, water stains, sweat stains, etc.)during the using or process,it is a important index of textile.The product has good colour fastness and it not easy to lose color during processing or using;otherwise it will appear some states like drop or stain and cause a lot of trouble. The most conventional problem of colour fastness of textile as below: 1、Sun fastness is not up to standard: The clothing during the dressing ,the color of the part of clothing that more exposed to sunlight begins shallow or discolored (usually is the back and shoulders), where there is no or less exposure, the color is constant or light. People will not use the product that the color is different in depth. 2、Colour fastness to washing, soaping and dry cleaning is not up to standard:Clothing fading after washing.The silk,wool,cotton clothing is easy to have such problems mostly.   3、Color fastness to friction is not up to standard:Textile during using,there is different fading degree in different part that has different degrees.And the part most easy to fading is jacket, sleeve, elbow, collar, and armpit,also the buttocks and knees of the trousers.      The product has poor color fastness that brings the bad shopping experience for consumer and the bad influence for brand public praise.Due to reduce this negative effect for minimum level,we should launch a strict test about color fastness when the product is finished. GESTER is a company specialized in textile testing equipment,there are some Colour fastness testers from us will introduce for you to strength the color fastness and improve the quality of product ,as below: 1、GT-D07  Colour Fastness & Fabric Washing Fastness Tester 2、GT-D09  Fabric Color Fastness To Perspirometer 3、GT-D02  Environment Xenon Weathering Test Chambers 4、GT-D04  AATCC Electronic Crock Meter
