The melting point is the temperature at which a solid changes (melts) its physical state from solid to liquid. The temperature at which the opposite action occurs (ie, changes from liquid to solid) is called the freezing point. Unlike boiling…
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 hydrostatic pressure resistance index is one of the most important indicators of waterproof and breathable fabrics. Hydrostatic pressure refers to the resistance water encounters as it passes through fabric. Under standard atmospheric pressure conditions, the fabric is subjected to…
Fabric dimensional stability refers to the shortening or elongation of fabric length during wearing, washing, storage, etc. Among them, shrinkage is one of the most concerning phenomena. The shrinkage of the fabric not only affects the appearance of the fabric,…
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…
Yarn count introduction What is yarn count? Yarn count is a number which indicates the mass per unit length or the length per unit mass of yarn. Classification Generally, there are four representation ways of yarn count: Tex, Denier, Ne…
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 tension is used to measure the tension of moving or static yarn, thin steel wire, and plastic wire, providing a reliable basis for improving material quality and product performance. Yarn tension Generally speaking, "yarn tension" can be understood as…
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,…
The testing items in the textile testing laboratory are divided into fiber testing, yarn testing, and fabric testing according to material classification. In the following content, we will introduce the relevant information on fabric testing according to the different properties…
We usually divide fibers into natural fibers and man-made fibers. Fiber samples are generally available in three forms: ① Loose fiber; ② A yarn may be contain one fiber type or multiple fiber types; ③ Woven or knitted fabrics may…
As an important production equipment of cotton mill, roving frame belongs to the preparation process from combed sliver to spinning into yarn in the production process. Roving production is the last of the preparatory stages for spinning. The tasks of…
