sanitary paper

Sanitary papers, a category including toilet tissue, toweling, facial tissue, and napkins, are designed for softness, bulk, and absorbency. These qualities are achieved through minimal refining of the pulp and a process called machine creping, which softens the paper sheet. Facial tissue is dry-creped, while toweling is often creped while still wet. Napkins are typically heavier than tissues and can be embossed with patterns. Due to their soft texture, sanitary papers are relatively weak but are often treated with resins to increase their strength when wet, which is crucial given their intended use. A sanitary napkin, also known as a menstrual pad, is a disposable absorbent pad used to absorb uterine flow.12
