Fabric Air Permeability Tester

Principle And Test Conditions Of Fabric Air Permeability Tester

The fabric air permeability tester is used to measure the air permeability of a variety of textile fabrics, including industrial fabrics, coated fabrics, industrial filter paper, filters, filter materials, non-woven fabrics and other textile products and other breathable materials. Breathability is the ability of air to pass through a fabric. It is expressed as the rate of air flow vertically passing through the sample under the specified test area, pressure drop and time conditions. ​ Principle of breathability test: [...]

What Tests Can The Fabric Air Permeability Tester Be Used For?

The fabric air permeability tester is an instrument used for air permeability testing. The gas permeability test we often refer to refers to the detection of specific gas permeability of materials with certain gas barrier properties. Most of these materials are polymers or multi-layer composite materials made of polymers, and are widely used in product packaging in food, medicine, chemical industry, electronics, military industry and other fields. Among them, materials with excellent barrier properties (low gas permeability) can be [...]

What Is The Oxidation Induction Tester (OIT)

The oxidation induction tester is an important tool for evaluating the oxidation resistance of materials. In many fields, such as the food industry, plastics manufacturing and materials science, understanding the antioxidant properties of materials is critical to product quality and longevity.   This tester is based on the oxidation process of materials and evaluates the stability of materials in high temperature, high pressure and oxygen environments by simulating accelerated oxidation conditions. It measures when a material begins to oxidize within a [...]

Thermal Gravimetric Analyzer

What Are The Common Faults Of Thermogravimetric Analyzer(TGA)

Differential Thermal Gravimetric Analyzer, TGA Thermogravimetric Analyzer is an instrument that uses the thermogravimetric method to detect the temperature-mass change relationship of substances. The thermogravimetric method is to measure the relationship between the mass of a substance and the change of temperature (or time) under programmed temperature control. When the measured substance sublimates, vaporizes, decomposes out of gas or loses crystal water during the heating process, the quality of the measured substance will change. THERMO GRAVIMETRIC ANALYZER(TGA) Common problems encountered by [...]

COMMON PROBLEM OF THERMOGRAVIMETRIC ANALYZER(TGA)

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 usually due to failure of the adhesive. Although the material used in the adhesive is resistant to high temperatures, when the test sample is cycled or maintained at high temperature (above 600°C) for a long [...]

How To Measure The Pet (Polyester) Glass Transition Temperature?

In order to study the quality and characteristics of materials, many industries use differential scanning calorimeter (DSC) to test the glass transition temperature of materials, especially the glass transition temperature of PET (polyester), which is also a relatively common measurement. Differential Scanning Calorimeter  What is glass transition temperature? Glass transition temperature (Tg) refers to the temperature corresponding to the transition from glassy state to high elastic state. Glass transition is an inherent property of amorphous polymer materials and a macroscopic manifestation of [...]

Common Test Methods and Comparison of Fabric Water Vapor Permeability

What is Fabric Water Vapor permeability?         The Water Vapor permeability test of textile fabrics is mainly to test the Water Vapor permeability of fabrics under different temperature and humidity. It is to simulate the ability of textile fabrics to transfer the body to naturally discharge water vapor to the external environment after simulating the sweating state of the human body under different activities. Water Vapor permeability is the quality or efficiency of water vapor transmitted on both sides of the fabric; the [...]
