In optics, irradiance is the power per unit area of electromagnetic radiation incident on a curved surface. Radiant emittance (radiant exitance) is the power radiated from a surface per unit area. Using the International System of Units, the units of…
The contact angle refers to the angle formed when the liquid phase is sandwiched by the gas-liquid interface and the two tangents of the solid-liquid interface at the solid surface of a liquid drop on a solid horizontal plane. It…
As people's living standards improve, their requirements for life are also gradually increasing. Textile, an industry closely related to life, has also developed rapidly. In particular, the comfort of clothing or home textile products is one of the most important…
The heat and water vapor transfer properties of textile fabrics are major determinants of the wearer's thermal comfort. The heat resistance of a fabric represents a quantitative assessment of the thermal barrier effectiveness the fabric provides to the wearer. The…
Definition of viscosity Viscosity refers to the resistance a fluid exhibits to flow. When a fluid (gas or liquid) flows and one part flows over another, it encounters resistance, which is the internal friction of the fluid. To make the…
Air permeability is a widely used test that measures the ease with which air can pass through a fabric and helps to indicate the air permeability of the fabric, especially for wind-proof, weather-resistant, and water-resistant fabrics. YG461F Fully Automatic Air…
The moisture regain of textile materials when they reach equilibrium under standard atmosphere is called standard moisture regain. The actual moisture regain of each fiber and its products varies with temperature and humidity conditions. In order to compare the moisture…
Twist test is an important part of yarn inspection. It is related to the strength, elongation, appearance, style, etc. of yarns and fabrics. Different yarns have different structural characteristics, and their twist testing methods are also different. Basic concept To…
Yarn hairiness refers to the fiber ends or loops that stick out of the main body of the yarn. Since the fibers located on the surface of the yarn are not closely connected with the main body of the yarn,…
Fiber strength refers to the ability of fiber to resist external damage, which largely determines the durability of textile products. Common indicators Fiber strength: Absolute strength, the maximum load that a fiber material can bear when it is stretched to…
Fiber length directly affects the processing performance and practical value of the fiber and reflects the quality and performance of the fiber itself, so it is one of the most important indicators of the fiber. Fiber length definition Natural length:…
Fiber fineness refers to the thickness of the fiber. Fineness is one of the important morphological dimensions and quality indicators of fibers. Fiber fineness is closely related to spinning process and yarn quality, and directly affects fabric style. Fiber fineness…
