Today’s cigarettes basically have filters, but do you know what materials the filters are made of? Cigarette filters are made of acetate fiber tows. The world produces about 1 million tons of acetate fiber every year, and nearly two-thirds of the production is used to produce cigarette filters.

Acetate fiber used as filter material

Acetate fiber, also known as cellulose acetate fiber, is a man-made fiber made from acetic acid and cellulose through an esterification reaction.

In 1865, French chemist Paul Schützenberger invented cellulose acetate; in 1903, German chemists Arthur Eichengrün and Theodore Becker invented soluble cellulose acetate.

Acetate fiber is divided into two types: diacetate fiber and triacetate fiber. 74% to 92% of the hydroxyl groups in diacetate fiber are acetylated, and at least 92% of the hydroxyl groups in triacetate fiber are acetylated. Usually diacetate fiber Ester fiber is also called acetate fiber for short.

China National Tobacco Corporation and the American company Celanese have joint venture factories in Nantong, Zhuhai and Kunming to produce acetate fiber for cigarettes.

Hollow acetate fiber has dialysis function and can also be used for purification, separation and purification in medical, chemical and other fields.

Acetate fiber used as textile material

In addition to being used for smoking, acetate fiber can also be used in textile weaving.

Diacetate fiber is produced by spinning diacetate cellulose obtained by partial saponification of triacetate fiber as raw material. Diacetate fiber has good hygroscopicity and excellent wearing properties. Its filaments have an elegant luster, soft hand, and good drape. They resemble real silk. They are suitable for making underwear, shawls, skirts, and interior decoration fabrics.

Triacetate fiber is produced by spinning triacetate fiber obtained by complete acetylation of cellulose. Triacetate fiber is similar in performance to diacetate fiber, but has lower strength and higher melting point.

Finally, I would like to remind everyone that smoking is harmful to health. If you refuse cigarettes, you will not only have a healthier body, but you can also use the acetate fiber used to produce cigarette filters to make many beautiful clothes. Wouldn’t it kill two birds with one stone and get the best of both worlds!
