cellulose acetate
Noun: 1. A synthetic compound derived from cellulose: Cellulose acetate is an ester formed by the chemical reaction of cellulose (a natural polymer found in plant cell walls) with acetic acid and acetic anhydride. It is a thermoplastic material that can be spun into fibers, cast into films, or molded into various forms.
Cellulose acetate is primarily used as a material in manufacturing. It is valued for its clarity, toughness, and ability to be modified for specific properties. * It is used in the production of textiles, photographic film, eyeglass frames, and tool handles. * A common form is cellulose acetate film, which was historically the standard base for photographic and movie film. * As a fiber, it is known for its silk-like appearance and is used for linings, lingerie, and ribbons.
- The vintage dress was made from a luxurious cellulose acetate fabric that mimicked silk.
- Archival films from the mid-20th century were often recorded on cellulose acetate, which can degrade over time if not stored properly.
- Many modern eyeglass frames are lightweight because they are manufactured from cellulose acetate.
- Diacetate vs. Triacetate: The term "cellulose acetate" can refer to different esters depending on the degree of acetylation. Cellulose diacetate and cellulose triacetate have different properties, such as melting points and solubility, making them suitable for different applications (e.g., textile fibers versus high-performance film stock).
- Acetate: A common shortened, informal term for cellulose acetate, especially when referring to fibers or fabrics (e.g., "an acetate lining").
- Cellulose: The natural, raw material polymer from which cellulose acetate is derived.
- Thermoplastic: A category of plastics, including cellulose acetate, that become moldable when heated and solidify upon cooling.
- Acetate (in context)
- Synthetic fiber (when referring to its textile form)
- Plastic film (when referring to its photographic form)
- Cellulose acetate film: A specific, transparent sheet material used for photography, packaging, or overlays.
- Cellulose acetate fiber: The filament or yarn form used in textiles.
- Acetate rayon: A type of rayon made from cellulose acetate.
-
an ester of acetic acid; used in fibers and fabrics; photographic films and varnishes
