Flame-retardant non-woven fabric with composite polyester fibers
A recently granted patent (Publication Number: US11965274B2) discloses a non-woven fabric made of composite polyester fibers with a core-sheath structure. The fabric includes a non-woven fabric body containing the composite polyester fiber in an amount ranging from 15% to 80% by weight. The apparent density of the fabric is between 0.005 g/cm3 and 0.040 g/cm3, with specific bending resistance values in different directions.
Furthermore, the patent claims specify that the non-woven fabric can have a basis weight between 40 g/m2 and 80 g/m2, with a bending resistance ratio falling within a range of more than 1.0 and 4.0. Additionally, the fabric may include a flame-retardant fiber in the rest of the composition, such as a flame-retardant acrylic fiber or a flame-retardant polyester fiber. The patent also mentions the use of this non-woven fabric in filters for preventing stains in range hoods or ventilation fans, highlighting its potential applications in various industries.
