A tensile testing machine is a type of testing equipment that is essential in processes such as material development, physical property testing, education and training, quality control, material inspection, and random inspection on production lines. It is used to conduct…

Introduction Colorfastness refers to the ability of a material or substance to retain its color when exposed to various environmental factors such as light, heat, water, and other chemicals. It is a measure of a material’s resistance to color fading,…

Introduction The materials and products commonly used in our daily lives, such as textiles, plastics, leather, coatings, building materials, etc., will age over time due to comprehensive damage caused by factors such as light exposure, heat and cold, wind and…

Cotton is the most important natural textile fiber, as well as cellulosic textile fiber, in the world, used to produce apparel, home furnishings, and industrial products. Worldwide about 40% of the fiber consumed was cotton. But how much do you…

The Relations between wool fiber’s structure and properties and evaluation of quality of wool fibers. Wool is a fiber, or modified hair, that grows from the skin of sheep. Because it is formed as a living substance, its growth is…

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…
