Yarn can be made from various types of fibers, which can broadly be classified into natural and synthetic categories. Natural fibers include animal-based fibers like wool from sheep, alpaca, and silk from silkworms, as well as plant-based fibers such as cotton and linen. Synthetic fibers, on the other hand, are man-made and include materials like polyester, acrylic, and nylon. Each type of fiber has its unique properties, affecting the texture, durability, and care requirements of the yarn. For example, wool is known for its warmth and elasticity, making it ideal for winter garments, while cotton offers breathability and softness, perfect for summer wear. The choice of yarn fiber depends on the project's requirements, personal preference, and budget.

Polypropylene wax is utilized in various applications thanks to its excellent properties. It acts as a lubricant in the plastic manufacturing process, reducing viscosity and improving flow. In ink formulations, it enhances rub resistance and slip characteristics. PP wax also plays a critical role as a dispersing agent in color masterbatches and as a modifier in hot melt adhesives, offering better stability and adhesion qualities. Furthermore, in the coatings industry, it's added to improve scratch resistance and surface properties of finished products. Its versatility and effectiveness make it a key component in numerous industrial applications, contributing to improved performance and quality of end products.
