Abstract
A method for manufacturing a sound-absorbing and heat-insulating composite fabric is provided. Accordingly, the composite fabric can maximize heat insulation and sound absorption performance, so that it can be utilized as an ultra-thin and ultra-lightweight sound-absorbing and heat-insulating material compared to conventional sound-absorbing materials. Therefore, it can be applied not only to transportation means including automobiles, ships, trains, and airplanes, but also to construction structures such as buildings and factories, and the like to simultaneously exhibit sound absorption and heat insulation.
Claims20
A method for manufacturing a sound-absorbing and heat-insulating composite fabric, comprising steps of:
- (1) preparing a first fiber web comprising first fibers, and a second fiber web comprising second fibers, wherein the first fibers comprise aerogel particles and have a diameter of 1 μm or less, and the second fibers have a diameter larger than the diameter of the first fibers;
- and
- (2) laminating the first fiber web and the second fiber web by applying heat and pressure.
A sound-absorbing and heat-insulating composite fabric, comprising:
- a first fiber web comprising first fibers, wherein the first fibers comprise aerogel particles and have a diameter of 1 μm or less;
- a second fiber web comprising second fibers, wherein the second fibers have a diameter larger than the diameter of the first fibers;
- and
- a fusion portion positioned at an interface between the first fiber web and the second fiber web to bond the first fiber web and the second fiber web.
