A cotton item refers to any product made from cotton fibers, which are derived from the cotton plant. Common examples include clothing such as t-shirts, jeans, and undergarments, as well as household textiles like bed sheets, towels, and curtains. Cotton is valued for its softness, breathability, and versatility, making it a popular choice in both fashion and home goods.

Surgical cotton, also known as absorbent cotton, is manufactured through a process that begins with the selection of high-quality cotton fibers, which are then cleaned to remove impurities. The fibers are then carded to separate and align them, followed by the removal of any remaining contaminants through bleaching and sanitization processes. The cleaned and processed cotton is then compressed and packaged into rolls or pads, ensuring it meets stringent medical standards for sterility and absorbency before being distributed for surgical use.

Cotton pliers are dental instruments primarily used for handling and placing cotton rolls or other soft materials in a patient's mouth. They allow dentists to maintain a clean and dry working area by managing moisture and ensuring that materials are positioned accurately without direct contact with fingers. Additionally, cotton pliers can be used to retrieve small items from the oral cavity, enhancing the efficiency and safety of dental procedures.

Cotton is typically stored in bales, which are tightly compressed and wrapped in protective materials to prevent damage from moisture, pests, and contaminants. These bales are then placed in a cool, dry environment to minimize the risk of mold and degradation. Proper labeling and monitoring of storage conditions are crucial to maintain the quality of the cotton until it is processed or sold. Additionally, storage facilities should be well-ventilated to prevent humidity buildup.

Cotton is an excellent fabric for dyeing due to its high absorbency, which allows it to soak up dyes effectively, resulting in vibrant and long-lasting colors.
