Testile Testing Equipment

This test method Of  ASTM D4157  , Oscillatory Cylinder Method, covers the determination of the abrasion resistance of woven textile fabrics using the oscillatory cylinder tester . This test method may not be usable for some fabric constructions. The Oscillatory Cylinder test instrument  test Method is used primarily in North America. The test was originally developed to determine the ability of automotive tires to withstand road abrasion. This abrasion testing method has been modified to test all types of materials against abrasion. In its various iterations, the test can be used to test clothing textiles, leather, upholstery fabric, automotive tires and floor covering. Though considered a stringent test, the Wyzenbeek does not necessarily measure “real life” conditions. The fabric to be tested is stretched tight on a frame and then abraded in the warp direction with a piece of  cotton duck fabric.A second specimen of the same fabric is abraded in the...

Perspiration color fastness tester  is widely used in testing textile anti-sweat, sea water, saliva, distilled water and other color fastness.  Perspiration Tester Scope of application: all kinds of textile materials, textiles, perspiration and color fastness test and determination of various colored, colored textiles sweat, sea water, saliva, distilled water and other color fastness performance. Perspiration color fastness meter operation method: 1, as a printing and testing equipment, it is prepared according to the standard sweat, PH solution solution, PH range should be 4.3 ± 0.2, from the sample material cut 6x6cm test pieces, and cut the same size of multi-fiber cloth, The weight of the sample and the multi-fiber cloth. 2, place each test piece and a multi-fiber cloth in the diameter of 9cm, 2cm deep disc, in the dish plus anti-sweat soaking test pieces and multi-fiber cloth for 30 minutes. The test piece was repeatedly rolled and weighed until it w...

Flammability is dependent on a materials specific heat, thermal conductivity, decomposition and ignition temperatures, and the heat produced (heat of combustion) as the material burns.  In order to make comparisons between different materials, any flammability tests should provide results that can be expressed as numbers. Given the specific test standard,you will get the specific flammability tester . there are many kinds of tester that are used to test . The following is a fabric vertical flammability tester . fabric vertical flammability tester for measuring the vertical flame spread for childrens’ sleepwear, fabrics, other textile materials or resilient filling materials used in upholstered furniture. Comprises a draft free stainless steel cabinet with observation window and back wall painted black for easy test viewing. The different specimen holders and associated hardwares are dependent on the test standards. Automatic Gas Control System could easily control the combusti...

Qinsun  Vertical Flammability Chamber for measuring the vertical flame spread for sleepwear, fabrics, other textile materials or resilient filling materials used in upholstered furniture. Comprises a draft free stainless steel cabinet with observation window and back wall painted black for easy test viewing. The different specimen holders and associated hardwares are dependent on the test standards. Automatic Gas Control System could easily control the combustion process. Fabric vertical flammability tester is used for measuring the vertical flame spread of children’s sleepwear, fabrics (fabric burn test), and other textile materials or resilient filling materials used in upholstered furniture. Whether the sample and the sample rack are accurately installed is an important factor that affects the vertical burning test. When cutting the sample, you should try to cut flat and wrinkle-free samples. The upper and lower ends of the sample should be trimmed flush, the size s...

A mar is more limited to a close to the surface change in gloss or color as a result of a material microcrack due to chronic internal stress and strain. The broader aspect of abrasion involves a more gradual removal of surface material with a moving contact force similar to a bearing and wear motion. These preceding failure mechanisms remain an ongoing research subject on the molecular plastics level. In plastics surface scratch and mar testing, there have been developed many different test approaches usually tailored to a specific end-use application. Stated simply, it is hard to use just one applied test to fully characterize a plastic surface scratch or mar. So, a good approach is to correlate applied test results with fundamental failure data on an ongoing basis. This is the best route to establish new scratch and mar testing equipment and methods. Qinsun multi-finger scratch/mar tester is designed for a variety of automotive interior materials, such as plastics, rubber, le...

What is Air permeability ? Air permeability is an important factor in the performance of such textile materials as gas filter, fabrics for air bags, clothing, mosquito netting, parachutes, sails, tent age, and vaccum cleaners.  It can also be used to provide an indication of the breathability of weather-resistant and rainproof fabrics. Construction factors and finishing techniques can have an effect upon air permeability by causing a change in the length of airflow paths through a fabric.Fabrics with different surface textures on either side can have a different air permeability depending upon the direction of air flow. Air permeability tester Test Procedure: 1、Suction pump ‘A’ draws air through the test specimen ‘S’ at 20±2oC and 65±2% R.H. The rate of flow is controlled by the by – pass valve ‘B’ and the series valve ‘C’. 2、The rate of flow is adjusted until the required pressure drop across the fabric is indicated on a draught gauge ‘D’ which is graduated from 0 ...
