JWELL-PP+PET Two-component Sound-absorbing Cotton Production Line
Product Introduction
PP+PET two-component sound-absorbing cotton is a non-woven sound-absorbing material composed of 35% polyester fifiber with a diameter of 20-30 microns and 65% superfifine PP melt-blown fifiber with a diameter of 1-4 microns. Two-component sound-absorbing cotton is processed based on melt-blowout nonwoven technology combined with blowout microfifiber technology. Through this kind of blowing processing method, sound-absorbing cotton has both the width and hardness of PP melt-blowout material and the hardness of polyester fifiber. It absorbs the advantages of two raw materials and has excellent sound-absorbing performance, non-toxicity, mildew proof, moisture proof, good thermal insulation, easy assembly, environmental protection and other characteristics. When the acoustic vibration passes through the fifiber pores in the melt-blown two-component material, its energy is converted into heat energy under the action of friction loss, which can be effffectively inhibited.
Two-component PP+PET two-component sound absorbing cotton is mainly used in the automotive fifield, such as doors, rear car cover, tool panel, car beam, luggage tray, truck lining, car driving control panel shield, roof fabric lining, pillar A, pillar B, pillar C and other parts, a few applied in the fifield of construction.
