  • Hydroentanglement describes a versatile process for manufacturing nonwoven fabrics using foe, closely speed, high-velocity jets of water and entangles loose arrays of fibers. The resultant fabrics rely primarily on fiber-to-fiber friction to achieve physical integrity and are characterized by relatively high strength, flexibility, and conformability. These technologies can use efficiently the majority of all types of fibers and produce fabrics that could achieve properties equivalent to reverts. (omitted)

  • The sound absorption materials are generally classified by three types, such as porous, resonator, panel. All of these types are based on theory of energy transform from sound energy to thermal energy. At first, the sound energy transform from the porous type uses to friction and viscose resistance. Secondly, resonator type uses to resonance frequency, absorption coefficient reach the highest.(omitted)

  • Needle punching is a process for converting fiber webs into coherent structures by using barb needles. The results are the mechanical interlocking of fibers into webs. Nonwovens by needle punching is most versatile among the various methods and is widely used in the industry. The original process for the production of mechanical bonds in nonwoven fabrics is that which employs the natural felting characteristics of the wool fiber. (omitted)
