Acrylic fiber filaments are artificial fibers made from natural wood pulp. They are processed through acetylation to form cellulose diacids sheets, which are then subjected to dissolution, filtration, spinning, curling, and drying processes. Acrylic fiber filaments are non-toxic, odorless, have excellent filtration performance, good air permeability, good adsorption capacity, good thermal stability, and quick drying properties. They are also renewable and can be used as textile materials and precision filtration materials, and are applied in the fields of textile clothing and cigarette filter production.

The filter material used for cigarette filters, the biaxial acetate fiber filament bundle, has characteristics such as a large specific surface area, the ability to effectively adsorb and retain harmful components in the smoke, low resistance, excellent thermal stability, and good elasticity. Moreover, it does not alter the taste of cigarettes. Therefore, it is widely used in the tobacco industry. As a textile raw material, the biaxial acetate fiber filament bundle has good air permeability, no static electricity, and quick drying properties. The manufactured clothing is soft and smooth in texture, and has a firm shape, with a promising future. Currently, cigarette filters are the main application market for biaxial acetate fiber filament bundles.
China is a major producer and consumer of cigarettes. Since 2016, due to the national anti-smoking policies, the cigarette production in China has declined. According to the data from the National Bureau of Statistics, in 2020, the cigarette production in China was 2386.37 billion pieces, an increase of 0.9% compared to 2019, but still a decrease of 202.69 billion pieces compared to 2015. However, China remains the world's largest cigarette producer, and the country is continuously promoting the structural upgrading of the cigarette industry. The diacetyl fiber filament, as a high-performance cigarette filter material, still has a broad market space.
The major producers of diacrylic fiber filament in our country include Nantong Acrylic Fiber Co., Ltd., Zhuhai Acrylic Fiber Co., Ltd., Kunming Acrylic Fiber Co., Ltd., Double-Vi Eastman Fiber Co., Ltd., Xi'an Da'an Chemical Industry Co., Ltd., and Xi'an Huidai Chemical Industry Co., Ltd. Compared with Europe and the United States, the research on diacrylic fiber filaments in our country started relatively late. The early technologies were monopolized by foreign enterprises. At present, certain breakthroughs have been achieved, but the production still cannot meet the domestic market demand, and we still need to import from overseas markets every year.
According to the "In-depth Market Research and Investment Strategy Suggestions Report on Bisacrylamide Fiber Bundles Industry from 2021 to 2025" released by Newview Industry Research Center, in 2017, the import volume of bisacrylamide fiber bundles in China grew rapidly, with the growth rate reaching 144.6% and the growth rate of import value reaching 119.4%. From 2018 to 2019, it continued to show a high-speed upward trend. According to the data released by the General Administration of Customs of China, from January to December 2019, the import volume of bisacrylamide fiber bundles in China was 12,593.0 tons, and the import value was 66.381 million US dollars. This indicates that in the future, there is still a considerable space for import substitution in the bisacrylamide fiber bundles market in China.
A new industry analyst from New Vision Research stated that the boric acid fiber filament has excellent comprehensive performance and can be used in the fields of textile and clothing production, as well as cigarette filter production. It can also be used as a medical filtering material. Among these, cigarette filters are the largest market demand for boric acid fiber filaments. China is the world's largest producer and consumer of cigarettes. With the upgrading of the cigarette industry structure and the continuous improvement of product quality, the application proportion of boric acid fiber filaments in cigarette filters has been continuously increasing, and it has become the mainstream production material. The development prospects of China's boric acid fiber filament industry are broad, but at present, the production strength is still insufficient. Some product demands still rely on imports. There is still a large space for further progress in the future.
