High Speed Tensile Impact Testing Machine
The main difference between the ASTM F2634 − 15 High and ISO 13953 – Determination of the tensile strength and failure mode of test pieces [...]
The fabric shrinkage testing machine is an instrument used to measure the dimensional changes of textiles during washing, drying and other processes. It is widely used in textiles, clothing, home textiles and other industries, and is of great significance for ensuring product quality and [...]
(1) Test methods and indicatorsTest MethodWoven fabrics, non-woven fabrics: ripped yarn strip method, grab sample method, shear strip method
Knitted fabric: trapezoidal test strip, loop test strip. When the rectangular knitted fabric sample was stretched, the stress at the jaws was particularly concentrated, causing the [...]
The electromagnetic interference and response process generated by any electronic device can be used to describe the source of interference (test signal generator) by radiation and conduction, and the characteristics of the response receiving device can be described by radiation sensitivity and conduction sensitivity. [...]
The color fastness test is to simulate the color fastness of textiles under different environments or conditions. There are many kinds of color fastness test items, such as soaping resistance, water stain, sweat stain, light fastness, etc. Different test items have certain differences in [...]
1) The influence of the instrument
① Influence of buoyancy
a) When the thermal balance is in the hot zone, the weight of its components to displace the air during the heating process is decreasing, that is, the buoyancy is decreasing, that is, the performance of [...]
As an important equipment for testing the mechanical properties of materials, the standardization of operation and the timeliness of maintenance of the horizontal tensile testing machine are directly related to the accuracy of the test results. Therefore, mastering the correct operation methods and maintenance [...]
Thermal Gravimetric Analyzer TGA(1) The sample holder falls off
Careful observation of the structure of the thermogravimetric analyzer(TGA)
shows that there is a high-temperature-resistant and corrosion-resistant colloidal material, that is, an adhesive, between the tripod of the balance and the thermocouple. Detachment of the sample is [...]
With the continuous development of science and technology, the quality and performance requirements of textiles are also constantly improving. Among them, the air permeability of fabrics is one of the important indicators for measuring the quality of textiles. In order to ensure that the air [...]
