Shaped fibers are chemical fibers produced by spinning through spinnerets with specific geometric shapes, resulting in special cross-sectional shapes and functions. Conventional chemical fibers with circular cross-sections have disadvantages such as low surface luster, a waxy feel, susceptibility to soiling and pilling, poor water absorbency, and low covering power. Therefore, modifying these fibers to obtain improved performance has long been a continuous goal. Modification of synthetic fibers mainly includes physical and chemical methods, with physical methods being more common than chemical ones. Changing the fiber cross-section is a simple way to obtain different fiber properties and belongs to physical modification. Among physical modification methods, it ranks first and is the most important means for producing shaped fibers. Types, Functions, and Applications of Shaped Fibers Because there are many ways to modify fiber cross-sections, a wide variety of shaped fibers have been de...

  Friction is the phenomenon in which two object surfaces come into contact and move relative to each other under external force, generating tangential resistance at the contact interface. This tangential resistance is friction force, and its magnitude depends on the characteristics of the object surfaces. It is one of the classical mechanical properties. For fabrics, surface friction performance is also one of the most basic mechanical properties. It is generally characterized by the friction coefficient and surface roughness. The surface friction performance of fabrics affects their smoothness or slipperiness, contributing to the richness of textile surface hand. A low friction coefficient results in a smooth hand, while a high friction coefficient leads to a rough hand. Regarding auditory style, specially treated silk fabrics produce low-frequency vibrations when rubbed together, creating the “silk sound” effect, which provides a pleasant sensation when they contact the skin dur...

  Have you ever wondered how researchers, universities, and textile laboratories process and test new materials with high accuracy? One of the most important tools used for this purpose is the  twin screw extruder , a machine that helps you study how polymers, fibers, and additives behave under heat and pressure. Whether you work in a research institution, teach material science, or manage quality control in a textile or plastics facility, understanding this equipment is essential for producing reliable results. A  twin screw extruder —also called a  screw extruder  or  double screw extruder —allows you to mix, melt, and analyze different materials with great precision. This is why it is widely used for polymer development, product testing, and laboratory-scale experiments. If you want consistent data, efficient processing, and accurate material behavior analysis, choosing the right extruder becomes a key part of your work. This article will cover everythin...

The number of turns within a unit length of yarn is called twist. Twist is expressed as twists per meter (t/m) or twists per 10 cm (t/10 cm). Twist is an important physical property of yarn. The physical and mechanical properties of yarn are determined by the properties of the constituent fibers and the yarn structure, among which the twisting action is the most important factor affecting yarn structure. Short fibers can form yarns with certain physical and mechanical properties precisely because of twisting. Twist is not only the fundamental condition for yarn formation, winding, and strength development, but is also closely related to yarn strength and elongation at break. Therefore, twist testing must accurately reflect the true inherent twist of the yarn while being simple, fast, and accurate to operate. Different twist testing methods apply to different yarns. Some yarns can be tested by several methods, but differences among methods may lead to varying results. At present, the ma...

Every material we use in daily life—fabric, rubber, plastic, leather, flooring, and coatings—faces friction. This friction slowly removes surface layers, causing wear, fading, scratches, or even total material failure. To make sure products can survive real-world use, manufacturers rely on an  abrasion tester , a special machine designed to measure how strong a material is against rubbing, repeated contact, and surface damage. Understanding abrasion resistance is important for industries like textiles, automotive, packaging, footwear, construction, and electronics. A reliable  abrasion testing machine  helps brands check product durability before releasing it into the market. This ensures quality, reduces customer complaints, and builds long-term trust. In this comprehensive guide, we will explain what an abrasion tester is, the main types used in laboratories, how they work, key performance parameters, pricing, standards, and how to choose the right model for your needs....

  Carbon fiber possesses excellent properties such as light weight, high strength, high modulus, corrosion resistance, low thermal expansion, fatigue resistance, and good biocompatibility. It not only retains the intrinsic characteristics of carbon materials but also combines the flexibility and processability of textile fibers, forming a brand-new material system together with its composites. Among these, two-dimensional and three-dimensional carbon fiber fabrics are indispensable components of carbon fiber composite materials. Composite materials reinforced with carbon fiber fabrics (CFRP) are regarded as advanced high-tech products and are widely used in sports equipment, construction reinforcement, transportation, aerospace, and other fields. Owing to their outstanding performance, carbon fibers and their fabrics have become essential materials for countries around the world. Weaving Technology of Carbon Fiber Plane Fabrics Common types of carbon fiber plane fabrics are mainly ...
