A wet spinning machine is used to form fibers from a polymer solution (often called a spinning dope) by extruding it through a spinneret directly into a coagulation bath. In that bath, the polymer precipitates and solidifies into filaments, which…
In polymer science and industrial manufacturing, material consistency is never accidental. Whether you are working in a university laboratory, a polymer research institute, a textile fiber production line, or an industrial quality control department, the flow behavior of molten plastics…
The quality of warp preparation largely depends on the warping process. The better the warping process, the better the warp knitting quality, and achieving high-quality warp knitting production is already halfway to success. Warping is a weaving preparation process that…
When you are responsible for testing material performance, accuracy is critical. In research institutions, universities, and textile or plastic manufacturing facilities, knowing how materials react to sudden impact is essential. Impact behavior plays a key role in quality control and…
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…
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…
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…
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…
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…
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…
In textile manufacturing, every process—from spinning to finishing—shapes the final fabric quality. One vital yet often overlooked step is warp preparation, especially the sizing process. Before weaving, yarns must be strong, smooth, and flexible to handle the tension of the…
Ramie is a perennial herbaceous plant known for its strong, lustrous fibers with excellent moisture absorption and breathability. However, due to the presence of pectin, hemicellulose, and other gummy substances, raw ramie is stiff and difficult to spin. Degumming removes…
