    Experiment tells you: Why there is a bonding gap or crack in your shoes? September 06, 2018
    Does below situation happens to your new shoes with a bonding gap or sole-crack for wearing within a short time? Just as below pictures: What happens? You might say the quality of the shoes is not so well, so where the problem lies in? The reason why this situation appears is that the the flexing resistance of the finished shoes is a failure. The flexing resistance of finished shoes refers to the finished shoes’ durability for the bending or folding under a certain temperature and certain force. General speaking, it’s a repetition twisting process between human foot and shoes. The test standard for shoes flexing resistance: GB/T 3903.1-2017Footwear,Test Method for  Whole shoe , Flexing Resistance.This test standard is used for test whole shoes and sole, not suitable for the heel excess 70mm, or the part of sole’s flexing more than 25mm,or the finished shoes with strong stiffness. This is Flexing Resistance Tester: The testing principle of Shoes Flexing Tester is to use a cutting knife cut a crack with specified length of whole shoes or sole, then to do the flexing test under certain angle and rate. After test, measure the length of the crack and at the same time, observe the changes of the joints of the upper surface, the sole and the bottom (including the fence and the bottom wall). Move like this: Is it a similar motion when you are walking? Each test should need not less than a pair of whole shoes or sole.  The test bending angle should be (50±1)°, the flexing rate should be (230±10)times/min. The test temperature should be (23±2)℃. Do the test for 40,000.00 circles. As below pictures show: The standard requires the cutting position should be in the middle of the toe flexion of the sole of the shoe, and the sole needs to be cut through. As showed in the pictures: Not all the shoes need the cutting crack in advance, different standards requires different specification. For example: Sneaker (GB/T 15107-2013) It requires not cutting, and it continually bends 40,000 times, the qualified products should not be crack after the bending. The bottom wall, upper bottom the shoe sole should be ≤5.0mm;After folding, the shoe sole shall not have more than 3 cracks, and the longest crack length shall be ≤5.0mm;The sole must not appear Color falling off; air (liquid) cushion should not appear air leakage (liquid) or collapse phenomenon after folding the air cushion shoe. leisure shoe (QB/T 2955-2017) It requires cutting 5.0mm in advance, qualified products require that the length of the cut opening is ≤ 20.0mm after bending. The new crack length is ≤ 5.0mm after folding, and should not exceed 3 places. After the fold, there should be no cracking on the face, cracking or opening the bottom, and is no testing the fold resistance if the shoe size is below 230mm. Natural leather out sole also does not measure wear resistance. Test Results: 1.Number of newly generated cracks and longest new crack length, glue failure length of the bonding part of t...

  • How to test the bending strength of footwear?
    How to test the bending strength of footwear? July 31, 2018
    Rubber is widely used in shoe industry. Usually, the shoe sole is made of rubber which is more elastic and more comfortable,Quality is of first importance in shoe industry. Only to use good rubber, manufacture can produce the quality shoes which have good elastic and flexing resistance.Therefore,it is important to use the high quality footwear testing equipments to test the shoes rubber property before starting the shoes production process. About Rubber/shoe sole The main problem of rubber sole is that when the rubber can’t meet the required standard, it is easy to cracks and can’t withstand the bending force.To test the flexing resistance of rubber, rubber manufacturers exert flexural forces to the rubber which greatly extend the service life of the rubber.Shoes manufacture should use the footwear testing equipments to test the rubber crack resistance and shoe sole flexing resistance to make sure the quality of footwear. How to test the crack resistance of rubber? Footwear testing equipment is widely used to test the quality of rubber,such ad elasticity,flexibility,etc.GT-KB06 EN Sole Flexing Tester is to determine the bending resistance of rubber.During the test, clamp the sample in the machine, exert bending strength to the sample, it can help to evaluate the flexing degree of rubber. Meanwhile, The machine also helps determine whether the material can survive long periods of bending force. GESTER is specilized in manufacture the testing equipment, providing high quality footwear testing equipment. All of our instruments follow the test standards which is provided by standardization departments. GESTER provides various rubber testing machine,such as GT-KA01-2 Whole Shoes Flexing Tester, GT-KB08 DeMattia &Upper fletester, GT-KB05A ROSS Flexing Tester, etc. For more information on rubber or footwear testing equipment, please contact us.

  • Common problems in hydrostatic pressure testing
    Common problems in hydrostatic pressure testing July 23, 2018
    The waterproof property of the fabric is mainly divided into the resistance of the fabric to water wetting and the resistance of the fabric to water infiltration. The waterproof property of the fabric is characterized by the grade of water contamination, the grade of resistance to static water pressure, the permeability of water, etc. The testing methods are mainly divided into the dip method (spray method) and the static water pressure method. Common Problems happens during testing Improper operation may affect the results during hydrostatic pressure test. The following situations may affect the test results. To make sure there is no air between the sample and water before clamp the sample, then clamp the sample for test. If there is any air between sample and water, then water can't completely touch with specified test area, finally there will not appear water droplets in some part of the sample area, it will also affect the test result. During the test, try your best to ensure that the edge of the sample clamping device does not leak water and water. If the sample water seepage, leakage, on the edge of the clamping device testing will have water leaking from edge clamping device, sample test pressure can appear unstable phenomenon, it does not guarantee the accuracy of experimental results, will affect the result of the experiment. >>>GT-C26B Hydrostatic Pressure Testing Machine Determination of test end points Hydrostatic test standard, GB/T 4744-2013 textile waterproof performance testing and evaluation of hydrostatic pressure law provisions recorded in the presence of water samples on the third place of hydrostatic pressure value, test the finish for the third water droplets appear. If the test endpoint is not selected correctly during the test, it will have a direct impact on the reading of the experimental results, and the incorrect experimental results will be obtained.>>>GT-C26A Hydrostatic Head Tester for Textile Some special cases are as follows: If a third place water droplets appear on the edge of the clamping device, and leads to the third place drops of hydrostatic pressure value is lower than the same samples of other normal sample minimum, should eliminate this data, supplementary sample test separately, until get the normal experimental results. Under normal circumstances, the specimen edges due to the pressure of the clamping device, the edge of the specimen, prone to damage test, edge may be seeping water, in this case, is the analysis of the experiment test results, analysis of whether there lowest test value is lower than other normal sample, whether to need to supplement samples. In the standard annotations, if appear when the fabric rupture, water jet or compound fabric summon of filling water, record the pressure value, and introduced the experimental phenomena in the report. The above situations should be taken as the test end of the experiment. How to solve Exception? Hydrostatic test results discrete...
