What Is an Electronic Crockmeter — The Complete Guide Color fastness refers to the ability of textiles to maintain their original color when exposed to common challenges throughout their service life. High color fastness is crucial for meeting performance requirements, especially in the apparel sector. Color fastness testing generally includes light fastness, weather fastness, wash fastness, rubbing fastness, perspiration fastness, etc. In some cases, different textiles or usage environments require special color fastness evaluations. This article mainly focuses on rubbing color fastness, which evaluates a fabric’s resistance to color transfer when rubbed repeatedly on dry or wet surfaces. Rubbing Color Fastness Rubbing color fastness refers to the firmness of the printed fabric color when subjected to rubbing. The rubbing color fastness of colored materials depends on two main factors: the amount of floating color and the combination of dyes and fibers. The more floating color on the fabric surface, the poorer its rubbing color fastness. The testing method for rubbing color fastness is conducted on a Colorfastness to rubbing tester. Electronic Crockmeter The Electronic Crockmeter is used to determine the color fastness of textiles to dry or wet rubbing. A pinned acrylic sample holder ensures rapid sample mounting and repeatable results. GESTER AATCC Crockmeter Metal box, high-temperature baking coating, easy maintenance. Electric motor, fitted with a pre-determined electronic counter for strokes up to 9999; the experiment completes successfully with automatic stop. Standards of GT-D04 Crock Meter machine The most widely used standards are AATCC 8 and ISO 105 X12. A special instrument called a crocking tester is used to rub the test fabric with wet and dry undyed fabric for a specified duration. GESTER GT-D04 Electronic Crockmeter complies with these standards: BS 1006-D02, ISO 105-X12/D02, AATCC 8/165, ASTM D6279, JIS L 0849 Type 1, JIS L 0862 Type 1 Textile Crocking Tester Test Procedure First, lay the textile sample flat on the tester’s platform. Then, fix dry or wet standard white cotton onto the rubbing head. The warp and weft of the standard white cotton must intersect the sample at a 45° angle. Next, the rubbing head must travel along a 10 cm track on the sample. It must do this 10 times, once per second, in a straight reciprocating motion. The sample must be at least 20 cm × 5 cm, with the length in either warp or weft direction. The test is used to detect rubbing color fastness. It rubs the fabric in both the warp and weft directions. You must brush off any colored fibers remaining on the standard white cotton cloth. The test evaluates the staining level on the dyed white cotton cloth and the warp and weft directions using a grey (or colored) scale. How to Rate the Results A rating of four for dry rubbing and three to three-and-a-half for wet rubbing generally indicates good-quality material. These ratings show how much rubbing the fabri...

A Guide for Color Assessment Cabinet GT-D08 In the textile industry, color consistency has always been one of the most difficult factors to control, yet it is also one of the key elements that most affects the final quality. Colour matching cabinet: Colors appear differently under different lighting sources. To avoid/reduce the assessment error when performing color contrast, we can use a Light Booth / Viewing Booth / Color Light Box to simulate different light sources to obtain an objective assessment of color and color difference, anytime, anywhere. I. The Importance of the Color Assessment Cabinet Let’s begin with the simplest everyday example: when we go to a store to buy clothes, the special lighting in the store often makes a garment look very beautiful, leading us to purchase it. However, when we wear it outside or go back home, the visual impression greatly declines, and we might even feel that the color does not match and refuse to wear it again. The reason behind this is that under different lighting sources, the human eye perceives the color of the same object differently, which is called the metamerism effect. Metamerism is a common pain point in the textile industry due to factors including: Different light sources have different spectral compositions, which affect human color perception; Even slight differences in dye formulations may lead to different visual results under various lighting; Unstable dyeing control between production batches further increases the risk of color deviation; Natural light cannot remain stable for long, and weather and time changes will affect comparison results. For these reasons, professional environments must use equipment capable of simulating multiple light sources while ensuring long-term stability of the color observation environment—a color matching light box. It eliminates the influence of external conditions, allowing consistent color judgments across different times, personnel, and locations, thus ensuring stability in quality control. II. Features of GT-D08 Color Assessment Cabinet Color assessment cabinets render color more accurately. With 6 different light sources (D65, TL84, CWF, F, UV, U30), they can detect metamerism.

Understanding ISO 105 C06 and Washing Fastness Tester Color fastness testing is a very important indicator in textile testing. Textiles often face multiple external factors such as washing, rubbing, light exposure, and sweat during daily use, and the influence of washing is the most common. Therefore, “washing color fastness” is one of the essential testing items. Among the numerous color fastness standards, ISO 105 C06 is the most widely used and highly recognized international standard. It is known for its high rigor and clear parameters and is widely adopted by many testing institutions. To ensure accurate and reliable test results, it is necessary to use professional equipment designed in accordance with the standard, namely the ISO 105 C06 Washing Fastness Tester. GESTER wash fastness tester design parameter conform to ISO, BS, AATCC, JIS & SDC those standards. 1. What is the ISO 105 C06 Standard? Part C06: Colour fastness to domestic and commercial laundering This standard applies to the color fastness to washing test for various textiles in any processing state, focusing on evaluating the color change and staining of textiles under simulated household and commercial laundering processes. The testing principle is based on simulating actual washing conditions: washing, rinsing, and drying textile specimens together with specified adjacent fabrics. By controlling parameters such as temperature, alkalinity, bleaching action, and mechanical friction, reliable test results can be obtained within a reasonable period. The mechanical friction effect is achieved through a shorter liquor ratio and an appropriate number of steel balls. 2. Why We Need To Test Colorfastness to Washing? The clothing items we use daily must be washed several times before we throw them in the dustbin or recycle bin. So, the items may fade or self-stain after washing if their fastness property is not up to the mark. That’s why all the manufacturers try to maintain the wash fastness criteria provided by the retailers before exporting the goods. 3.

ASTM D4970 Test Method for Fabric Pilling Resistance Pilling is the little bits of fiber that gather together like a ball on top of your fabric, which affect appearance of the textile products. Pilling is fibre entanglement creating little balls of the fibres and has nothing to do with abrasion where fabric gets worn down. Pilling is caused by friction during wear, laundering and the characteristics of fabric itself. For example, taking clothes inside-out before washing can prevent some pilling. Pilling can sometimes be maintained or removed with a shaver while abrasion causes permanent harm (holes and tears). Genenrally, synthetics tend to pill more than natural fibers because their longer length and greater durability cause easy form of pills; on the other hand they are also less prone to be pulled out of shape.STM D4970 is an well-accepted standard for measuring the pilling resistance of textile fabrics using Martindale machine.  Overview of ASTM D4970 This test method covers the determination of the resis-tance to the formation of pills and other related surface changeson textile fabrics using the Martindale tester.The proceduregenerally is applicable to all types of fabrics, being particularlysuitable for woven fabrics.

How to Test the Water Resistance of Fabrics? Concepts of Water Resistance and Waterproofing Water Resistance – As commonly referred to in the industry, this term is actually a simplified form of “water-repellent.” The typical process involves adding a hydrophobic compound additive into the liquid tank at the entry of the finishing machine. The fabric is then passed through the tank for padding and drying, allowing the hydrophobic compound to deposit on the fiber surface, thereby achieving water-repellent performance. Waterproofing – True waterproof fabrics are superior to water-repellent ones in terms of durability and protection. They possess more stable physical and chemical properties, generally resisting washing and long-term use. The real goal of waterproofing is to form an impermeable barrier on one side of the fabric, ensuring a high level of hydrostatic resistance—typically 3000 mm or higher. To evaluate fabric waterproofing performance, industry-standard testing methods include hydrostatic pressure testing, spray rating testing, and rain testing. Fabric Waterproof Testing 1.

What Tests are Carried out on EN 407 Heat Resistant Gloves? EN 407 is a European standard specifically regulating the flame-retardant and heat-insulating properties of protective gloves. This standard applies to gloves used in environments involving high temperatures, flames, or thermal radiation, ensuring they effectively protect users from thermal injury. Scope of Application for Flame-Retardant and Heat-Insulating Gloves EN 407 Applicable to protective gloves and other hand protection equipment, including arm protection, intended for use by professionals and non-professionals. These provide protection against one or more forms of thermal injury, including flame, contact heat, convective heat, radiant heat, minor splashes of molten metal, or significant splashes of molten metal. Excludes gloves for firefighting and welding operations. What tests are carried out on EN 407 heat resistant gloves? Limited flame spread The first test a work glove should be subjected to is flammability resistance. Exposed to fire and in contact with an open flame for at least 15 seconds, how long will it take the glove to stop burning? It is this time period that will determine the performance level of the protective glove, on a scale of 0 to 4; below 3, the glove’s performance is not sufficient to claim high levels of protection for the other tests. GT-C35B Vertical Combustibility Tester This combustibility tester to determine the flammability resistance of vertically oriented fabrics and soft fabric toys. 1. Contact heat resistance test En contact avec When  in contact with a heat source between 100 and 500°C, at what temperature does the glove’s internal temperature increase by 10°C during the first 15 seconds? A glove with a level 2 rating guarantees perfect resistance to contact heat up to 250°C. GT-C101 Heat Contact Machine This test instrument applies to testing welders gloves resistance contact heat performance (for hand & wrist protection) in welding and related works process. 2. Convective Heat Resistance Test This convective heat resistance test measures the time (in seconds) that heat is transferred from a flame to the inside of the glove. The longer the protective glove is able to delay the transfer of heat from the outside to the inside of the glove, the higher its resistance level. The highest level is level 4. GT-C95 Heat Transmission Resistance Test Device To determine the heat transmission performance of textiles, fire-fighting supplies and other materials.
