Angora mohair yarn refers to the fine silk-like fabric or yarn made from the hair of the Angora goat, not to be confused with Angora rabbits, which produce Angora wool. Mohair is known for its high sheen, softness, and excellent insulating properties without being overly warm or heavy. It's durable, naturally elastic, and does not felt as easily as wool, making it a favorite for high-quality textiles, such as sweaters, scarves, and suits. A notable quality of mohair is its ability to take dyes exceptionally well, resulting in vivid, lustrous colors. Due to these desirable traits, mohair is often blended with other fibers to enhance its characteristics and the overall quality of garments or textiles.
Polymer plastics are synthetic materials created through a chemical process called polymerization, where small molecules known as monomers link together to form long chains or networks. The process typically begins with the distillation of hydrocarbons in crude oil to produce monomers like ethylene, propylene, and styrene. These monomers are then chemically bonded through various polymerization techniques such as addition (where monomers add to each other without losing atoms) or condensation polymerization (where monomers link together with the elimination of small molecules like water). The specific conditions under which polymerization occurs, such as temperature, pressure, and the presence of catalysts, determine the type of polymer plastic produced, its properties, and applications. Adjusting these parameters allows for the creation of a wide range of plastics with different characteristics, suitable for diverse uses from packaging and textiles to automotive parts and medical devices.
