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…
Breathability is another term for water vapor permeability. According to Wikipedia, a fabric's breathability is its capacity to let the passage of moisture vapor through it. It is especially crucial for active wear. You need more breathable clothing when your…
Since shuttle looms have obvious problems such as low weft insertion rate and poor product quality, shuttle looms are replacing shuttle looms, and shuttle looms will eventually be eliminated. According to different weft insertion methods, shuttleless looms include rapier looms,…
When the fabric is subjected to a specified pressure, the vertical distance between the front and back sides is called the thickness, generally expressed in millimeters. Fabric thickness has a great influence on the wearing properties of the fabric. For…
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…
In the previous article, we mentioned thermal and moisture comfort, which is one of the most important factors in the human body's subjective judgment of clothing comfort. An important heat dissipation function of the human body is carried out by…
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…
Fabric stiffness is one of the basic styles of fabrics and one of the key indicators that determine the beauty of fabrics and consumer preferences, such as the stiffness of suits, the softness of knitted underwear, and the stiffness of…
The crease recovery property of fabric is one of the important indexes to evaluate the properties of fabric. Measuring the crease recovery Angle of folded fabric samples by instrument is a common method to measure the crease recovery property of…
When fabrics are worn or used, they are often subject to concentrated loads perpendicular to the plane of the fabric. The fabric bulges and expands from one side until it breaks, such as at knees, elbows, shoe uppers, glove fingers,…
Fabric tear test is mainly used to test the tear resistance of film, sheet, soft polyvinyl chloride, polyvinylidene chloride (PVDC), waterproof coil, braided material, polyene warp, polyester, paper, cardboard, textiles and non-wovens. Tear strength test method Impact pendulum method Suitable…
