Latest Patents
Kammuri's most notable patent is for a "Polyolefin-type nonwoven fabric and method of producing the same." This invention involves a nonwoven fabric constructed from highly spinnable heat-bonded continuous filaments that are both strong and soft, offering superior tactile feel. The production process is meticulously designed to minimize defects to no more than 0.01/kg, with the fabric weight ranging from 10-100 g/m², and a bond percentage between 7-20%. The total hand value is calculated between 4-300 g. The innovative method includes melt-extruding linear low-density polyethylene to create filaments that are rapidly drawn and deposited on a moving collection belt, followed by heat treatment at a temperature significantly lower than the filaments' melting point. Furthermore, Kammuri's nonwoven fabric can incorporate both hollow and flat cross-sectional filaments, and it also allows for the utilization of bicomponent filaments comprising a sheath of linear low-density polyethylene and a core of polyethylene terephthalate.
