The Taber Abrasion Test Principle And Procedure

Strengthening control, the tests on the vamp material selected material with highwear resistance strength to the top of the shoe, shoe, such as easily damaged parts, in raising the overall durable performance and service life of shoes is of great significance. taber abrasion and wear tester and double-head taber abrasionand wear tester  have been recognized by more and more domestic and foreign customers because of its advantages such as simple operation, stable result and wide application range.


Taber Abrasion tester Test principle
Be placed on a rotating platform test samples, through the rotating platform as the above two rolling friction wheel, friction wheel under certain load and the specimen for rotating friction movement to wear. One friction wheel is outwards, and another friction wheel is in the inner friction sample. The abrasion marks are an overlapping ring. After the specified friction winding number, according to the surface wear condition and color change degree, the grading evaluation.

Test conditions
In temperature (20 + 2) ℃, humidity (65% + / - 5%) under the condition of test. Before the test, the sample should be placed in the standard environment of GB/ t22049-2008 standard environment for the environmental regulation and testing of shoes and shoes, and adjust the above 4h.

Abrasion and wear Tester test procedure
Fix the sample face up on the rotating platform and install the selected grinding wheel on the support pressure bar.
After selecting the appropriate load, put the support lever down, make the grinding wheel contact with the sample surface, connect and open the dust collecting device.
Start the instrument and test the number of cycles set by the counter. For vamp material, the number of friction is used 500 times.
After the test, remove the sample, check and record the abrasion of the sample, and use of the grey CARDS according to GB/T250-2008 "textile color fastness test assessment change color with the grey CARDS" qualification test area changes color and color fastness rating.

Classfication Of The Textile Testing

Textile testing is the term for a whole series of tests that examine the physical, mechanical and chemical properties of textiles. These tests are sometimes done before a textile goes into widespread use, or they're done on textiles arriving from other countries for sale in US markets. Countries like the United States have established standards for what should and should not be in textile products. Tests can show whether companies making textiles are in compliance or not. Many textile tests have many types. Some of them are physical tests, in which a sample of textile material is examined closely for feel and appearance. Such tests are done on individual fibers or strands of material and on yarns, threads made of several fibers twisted together. Textiles are subjected to light and other elements to see how they react. Some of these tests are done in a weather-ometer, a machine that tests for weathering and lightfastness of textiles. It's basically an enclosed box. Textiles...

Synthetic Blood Penetration Tester for Medical Face Mask

  Features of Synthetic Blood Penetration Tester: 1. Mask fixture is metal human head mold, which can fully simulate the actual use state of the mask. 2. Metal human head mold can be rotated at a certain angle, which is convenient for sample clamping. 3. Specially designed injection control device, a certain volume of synthetic blood can be sprayed in the controlled time. 4. Instrument uses a gas source that can provide (700±25) kPa stable air pressure. 5. It can simulate the liquid injection velocity corresponding to the human blood pressure 10.6 kPa、16.0kPa 、21.3kPa (i.e .80 mmHg、120mmHg、160mmHg) for the test. 6. A fixed target plate is provided to block the high pressure edge part of the ejected liquid flow, only the steady flow part is sprayed on the area sample, which increases the accuracy and repeatability of the test. 7. This blood penetration testing equipment uses imported special aluminum wire drawing panel, equipped with metal keys, sensitive operation, not easy to dama...

Determination of air permeability of a fabric-air permeability tester

Fabric air permeability is a measure to what extent it gives air passing through the fabric. Air permeability, a given area in the vertical direction of the air flow rate, a given time period, is measured by the fabric test area inside the pressure difference of the fabric. Basically, it depends on weight, thickness and porosity of fabric. The porosity of fabric is the demonstration of the air gap as a percentage within fabric. It has been important for especially the tent fabric, parachute fabric, raincoat fabric and garment, the fabric used in air bags, industrial filters and sail cloth. Moreover, when thermal properties of clothing and body interaction are taken into consideration, there has been the effect of air permeability. there is an instrument which is designed to test the air permeability of fabric on the market .it is air permeability tester . Air permeability is an important feature of fabrics (Sundaramoorthy et al., 2011) and is one of the main factors affecting the t...
