In the international trade of textiles, there are clear regulations on fiber composition labeling and identification, in order to reduce and avoid losses due to labeling specifications, it is necessary to pay attention to the composition labeling of textiles. This article…
When we get a fabric or buy a piece of clothing, in addition to the color, we will also feel the texture feel of the fabric with our hands and even to understand the basic parameters of the fabric: width,…
Testing the tensile properties of fabrics of ISO 13934 is divided into two parts: determination of maximum force and elongation at maximum force using the strip method and determination of maximum force using the grab method, the most complete guide…
In the tensile properties testing process of geotextiles, the elongation deformation is large, and the phenomenon of "necking" is easy to occur in the tensile process, and the width of the specimen has a great influence on the tensile strength…
What is a resistance band? A resistance band is a small physical training tool that is easy to carry, easy to use, and very effective. It is also called an elastic band, auxiliary band, tension rope, booster band and so on.…
★ What are industrial textiles? Definition of industrial textiles: Textiles that are specially designed with specific functions and used in industry, medical and health care, environmental protection, geotechnical and construction, transportation, aerospace, new energy, agriculture, forestry and fishery, etc. Industrial textiles are…
The planning and management of laboratory in printing and dyeing factory usually start from several aspects, such as blank fabric sampling, color sample management of customer, color card management of dyeing factory and color swatch formula confirmation, in order to…
Temperature humidity environmental chamber, also called climatic chamber, is a common environmental simulation system and device in laboratories and factories. Environmental chambers are used to test the performance stability of materials or products in various environments by simulating natural environments such…
COVID-19 has been going on for roughly two years now. In the face mask market, from the initial shortage of supply to the current basic balance between supply and demand, it will be increasingly important to reduce costs and improve…
In the manufacturing industry, the stability of products under various temperature and humidity conditions is the key to quality control. Temperature humidity chamber is one of the most common environmental control instruments that can quickly test the performance stability of…
Measurement is essential in all kinds of physical experiments and technology development processes, and as long as the measurement result, measurement error is inevitable. The error affects measurement accuracy, so the technical staff concerned must learn and master the theory…
The properties of a material in terms of deformation and damage under tensile forces can be measured by the tensile stress-strain curve, which is one of the most fundamental and important concepts in the mechanics of materials, come with me…
Although the electronic universal testing machine and hydraulic universal testing machine belong to the mechanical test equipment, but because of the two in the drive power source, the main body structure, and the application of scalability has a large difference,…
Tensile testers, also known as electronic tensile testing machines, can be used for various materials for tensile, compression, bending, shear, tearing, peeling, and other mechanical performance tests. Due to the powerful function and wide range of applications of the tensile…
Organic polymer materials, also known as molecular materials or high polymer, mechanical properties of which are strength, stiffness, hardness, plasticity, and toughness. Indicators reflecting these mechanical properties include yield strength, tensile strength, elongation, section shrinkage, impact toughness, fatigue limit, fracture…
