Application of viscose staple fiber and polyester staple fiber in the non-woven market

In recent years, the application proportion of viscose staple fiber and polyester staple fiber in the non-woven fabric industry has increased. However, due to performance constraints, their products are mostly used in the spunlace non-woven fabric industry, and a small part is used in needle-punched non-woven fabrics. In the textile industry, other non-woven fabrics account for very little. Viscose staple fiber high white viscose staple fiber for non-woven fabrics In 2019, China's viscose staple fiber industry has an existing production capacity of 4.985 million tons and an apparent consumption of 3.692 million tons, of which about 11% is applied to the non-woven fabric field. In the non-woven field, the requirements for the whiteness index of viscose fibers are higher. The industry usually refers to the viscose fibers used in the field of industrial textiles as'high white viscose fibers'. At present, there are 5 enterprises in the country that produce over-white viscose staple fibers. In 2019, the total output of high-white viscose staple fibers was 420,000 tons. At present, most of the domestic mainstream manufacturers of high white viscose staple fiber perform whiteness testing according to the ordinary viscose staple fiber testing standard (GB/T 14463-2008). At present, the whiteness of most companies has reached about 90%. Polyester staple fiber spunlace polyester staple fiber for non-woven fabrics In 2019, China's polyester staple fiber (melt direct spinning) industry will have an annual production capacity of 7.901 million tons, with an actual output of 6.2526 million tons, and domestic consumption around 5.62 million tons, of which 11.15% Applied to non-woven fabric field. The application of polyester staple fiber in the non-woven industry is mainly spunlace non-woven fabrics, while a small number of fields are used in the needle-punched non-woven fabric industry. In terms of specifications, the spunlace polyester staple fiber is mainly 1.56dtex*38mm, and the staple fiber for needle-punched non-woven fabrics is mostly 2.22dtex*51/65mm. From the point of view of origin, the current production of spunlace polyester staple fiber is concentrated in Jiangsu. Among them, the supply of Yizheng chemical fiber, Suzhou Jiangnan, Jiangyin Huaxi chemical fiber is basically the same, and Zhejiang, Anhui, Fujian have a small amount of spunlace Staple fiber is produced, with a total production capacity of around 900,000 tons, about 30% of which is for export.
