Introduction of acetate fiber


Cellulose acetate is a thermoplastic resin obtained by esterification of acetic acid or acetic anhydride under the action of a catalyst. CA is resistant to water, gasoline, mineral oil and grease, weak alkaline solution and acid, and has excellent weather resistance. Not resistant to ethanol, strong acid and strong alkali solutions.


It is necessary to dry the material before molding. Acetate fiber was born in the early 20th century, and was successfully trial-manufactured by the United Kingdom in the early 1920s and realized industrial production. At present, it is the second largest variety in cellulose fibers after viscose fibers. Acetate fiber can be used in the manufacture of textiles, cigarette filters, sheet bases, plastic products, and the like.


Types of acetate eyeglass frames

The plate frame is not easy to burn, the specific gravity is small, and the base arc is not discolored by the irradiation of ultraviolet rays. In addition, the hardness is large, the gloss is good, and it is durable. But it is not easy to bake and process, and the temperature is 115-130 degrees. The style is more beautiful, and it is not easy to deform after wearing.


Frame types are not only retro but also trendy frames, creating a classic eyeglass frame. Its workmanship has undergone complex processes such as turning, grinding, and polishing, so it is relatively high-end.


Acetate granules are extruded with an injection molding machine, called an injection frame.


Its characteristics are that it saves raw materials, can be mass-produced, has a lower cost, and is cheaper than a plate rack. But the firmness is not as good as the plate frame.


Because of its light weight and not easy to be allergic, the injection frame is more popular among the elderly and children's glasses. The injection frame is made of laminated plastic. Made by gluing a thin layer of plastic of one color onto another, thicker layer of plastic. Thick materials are mostly transparent pigments. There are also three or more layers of plastic.
