As titanium is hypoallergenic and does not react with human skin. titanium is often used in jewelry. especially for those with nickel or silver allergies.

Polyethylene (PE) and Polypropylene (PP) are both thermoplastic polymers used extensively in various industries due to their versatile properties. PE is renowned for its flexibility, durability, and resistance to moisture, making it ideal for packaging, containers, and insulation applications. It comes in various densities, providing a range of material characteristics. PP, on the other hand, is known for its stiffness, resistance to chemical solvents, bases, and acids, and a higher melting point compared to PE. This makes PP suitable for applications requiring a higher working temperature and rigidity, such as automotive parts, laboratory equipment, and reusable containers. Both materials are recyclable, which adds to their appeal in environmentally conscious applications. Choosing between PE and PP depends on the specific requirements of the application, including flexibility, chemical resistance, and thermal properties.

Ramie yarn is a natural fiber derived from the ramie plant, also known as China grass. It is known for its ability to hold shape, reduce wrinkling, and introduce a silky luster to the fabric's appearance. Ramie is one of the oldest fiber crops, having been used for at least six thousand years, and is principally grown in Eastern Asia. Despite its strength and durability, ramie is not widely used due to its high production costs and labor-intensive processing, which involves extracting the fiber from the plant's bark. However, its natural resistance to bacteria, molds, and mildew, along with its excellent absorbency and ability to dye easily, make ramie yarn a valued material in the production of textiles, especially for summer wear.
