Classification and comparison of test methods for fabric anti-drilling properties
Feather down is a natural material, which has the irreplaceable advantages of other materials. Down products are favored by consumers for their light, soft and warm characteristics. However, the drilling down problem of down products has always plagued manufacturers and consumers, and it is also one of the hot spots of complaints about the quality of down products. Therefore, studying the test method of fabric anti-drilling performance has very important practical significance for improving the quality of down products and reducing quality disputes caused by down drilling. 1 Feather down drilling mechanism Anti-drilling performance refers to the performance of fabrics to prevent feathers and down from drilling from its surface. It is expressed by the number of drilling down roots under specified conditions. Down fibers exist in the form of piles. In each pile, there are several fibers with basically the same internal structure. Each fiber will generate a certain repulsive force and keep the distance to the maximum, so that the down is produced. Fluffy. When the duvet is filled into the product, the down close to the fabric is repelled by the inner down and is squeezed outwards, generating an outward pushing force to make the down close to the fabric. Down has good resilience, no matter which direction it is pressed down, the fiber can quickly return to its original shape, but the air permeability of the anti-fleece fabric is usually poor, resulting in a large amount of still air stagnating in the down filling cavity of the down product. When the down product is squeezed or rubbed by the outside, the still air leaks out from the pores of the fabric or the needle hole of the suture, and the down takes the opportunity to follow the air to drill out of the inner cavity, forming drill down [1-2]. 2 Classification of anti-drilling test methods The research on the anti-drilling test method of fabrics has always been a bottleneck restricting the development of down products. In the 2008 version of the official test rules issued by the International Feather and Down Bureau, there is no description of the anti-drilling test method. In the product standards of down garments in our country, there is no specific requirement for the index of anti-drilling down. Scientific and effective test methods and test equipment have a significant impact on the research on the anti-drilling performance of down products. According to the testing principle and test equipment, the current testing methods for the anti-drilling performance of fabrics at home and abroad can be divided into 3 categories [3]: Turn box method: According to GB /T 12705. 2-2009 'Testing methods for anti-drilling performance of textile fabrics' Part 2: Turning Box Method, FTMS191A Method 5530-1978 'Test Method for Downhole Resistance of Fabrics Turning Box Method' test. Friction method: According to GB/T 12705. 1-2009 'Textile fabric anti-drilling property test method Part 1: Friction methodTest' test. Impact method: Test according to EN 12132.2-1998 'Test method for resistance to undercutting of feathers and down fabrics Part 2: Impact test'. 2. 1 Turning box method The turning box method was originally derived from the standard FTMS 191A Method 5530-1978 'Rolling box method for fabric underrun resistance test method' formulated by the US federal government in 1978. In 1991, my country also formulated GB / T 12705-1991 'Test Method for Downfall Resistance of FabricsThe basic principle of the rotating box method is: The sample is made into a sample bag of a certain size, filled with a certain quality of down and feather filling material, and placed in the rotating box of the test instrument equipped with hard rubber balls, and passed through the rotating box. It rotates at a constant speed to bring the rubber ball to a certain height and impact the sample in the box to simulate the various squeezing, kneading, and collision effects of down products during taking. Through counting the drills from the inside of the sample bag The number of down and feathers will be used to evaluate the anti-drilling performance of the fabric.
There are a wide variety of which are scientifically tested to have positive effects on the ability to tensile tester manufacturers. tensile tester manufacturers textile testing equipment is one of them.
Being a performance leader means GESTER International Co.,Limited will achieve operational excellence, industry-leading customer satisfaction and superior financial performance.
Obviously, financial return is important in manufacturing textile testing equipment, but I think that's not enough. I think many customers want to support something they really believe in.
The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
Personal protective equipment must meet specific performance requirements before it can be used in demanding workplace environments. ISO, EN, and ASTM standards provide important test methods and performance requirements for different PPE categories. However, the applicable standard depends on the product, intended application, target market, and specific protection requirements.
This guide explains the role of ISO, EN, and ASTM standards in PPE testing and introduces common requirements for safety footwear, protective gloves, protective clothing, masks, and safety helmets. It also explains how laboratories can select suitable PPE testing equipment according to the applicable test method.
