Asahi Kasei’s annual production capacity for of nonwoven fabrics in Japan is 34,000 tons of polypropylene spunbond nonwovens; 5500 tons of polyester spunbond nonwovens; 3500 tons of nylon spunbond nonwovens; 5500 tons of cupra spunbond nonwovens (trade name: Bemliese); 2000 tons of compound spunbond nonwovens (trade name: Precise); and 200 tons of meltblown nonwovens.
Asahi Kasei Spunbond Thailand (AKST) produces polypropylene spunbond nonwovens with the capacity of 35,000 tons/year in Thailand. The company recently decided to expand its polypropylene spunbond nonwovens with the additional capacity of 15,000 tons/year in Thailand, and the new facilities are expected to operate in July 2021. Therefore, the production capacity of polypropylene spunbond nonwovens in Thailand will increase to 50,000 tons/year.

Asahi Kasei has commercialized a nanofiber nonwoven fabric, a nonwoven with a wet process cloth of cellulose nanofiber (CNF) and a meltblown nonwoven fabric. The wet process nonwoven of CNF has been developed with the brand name of ‘NanoLeaf.’
There is a single-layered seat only by CNF, and the compound seat that is laminated to the single-layered seat to other nonwoven fabrics. The nonwoven fabric of cellulose nano fiber (CNF) has pushed forward the development for various uses such as filters, battery separators and reinforcement materials for the FRP. The meltblown nonwoven fabrics could be produced to the smallest fiber diameter to 300nm, and the polymer is made of nylon, and it could be produced with polypropylene too.
The nanofiber nonwoven fabric of the meltblown is used for the filter medium of liquid cartridge filters, and marketing has been pushing forward.
