The development of China's diacetate fiber tow industry has mainly gone through three stages. In the initial stage of the 1980s, at the beginning of reform and opening up, China's tobacco industry developed rapidly, the proportion of filter cigarette production increased day by day, and the demand for cigarette filter materials, especially diacetate fiber tow, increased sharply. However, at that time, China did not have the production capacity of diacetate fiber tow and was completely dependent on imports. After the establishment of China National Tobacco Corporation in 1982, it began to actively seek the production technology of diacetate fiber tow. In 1987, China National Tobacco Corporation and Celanese Corporation of the United States jointly established Nantong Acetate Fiber Co., Ltd . (Nanxian Company), som markerar början på Kinas lokaliserade produktion av diacetatfiberbogs .

In the development and growth stage of the 1990s, with the continuous growth of the domestic tobacco market and the increase in consumer demand for filter cigarettes, the demand for diacetate fiber tow increased further. In 1993, China National Tobacco Corporation further strengthened its foreign cooperation and established Kunming Acetate Co., Ltd. and Zhuhai Acetate Co ., Ltd . I joint ventures med relevanta företag, utvidgar produktionsskalan för diacetatfiber bogserar . under denna period, mognades produktionstekniken för inhemsk diacetatfiber gradvis och produktkvaliteten ständigt förbättrad .}}
From 2000 to the present, the stage of technological innovation and independent development, after entering the new century, China's tobacco industry began to focus on technological innovation and industrial upgrading, and put forward higher requirements for the performance and quality of diacetate fiber tow. After 2000, domestic diacetate fiber tow production enterprises increased their investment in tow variety diversification, low-denier tow production and new processes. In 2002, domestic tow successfully achieved diversification of specifications and varieties and serialization and personalization of production. In 2005, the high-density acetate fiber production technology independently developed by Nantong Acetate Co., Ltd. won the second prize of the National Science and Technology Progress Award, marking that China's diacetate fiber tow production technology has reached the international advanced Nivå . Under de senaste åren har inhemska diacetatfibertillverkare också utvecklat olika specifikationer för bogseringsprodukter enligt marknadens efterfrågan, till exempel 5 . 3y28000, 5 . 1y22000, 7. 3y36000, 6.0y54000, etc., till CigereTe -företag. Samtidigt utvidgar inhemska företag också aktivt utländska marknader för att förbättra sin internationella konkurrenskraft.
