Stitched felt prepared by utilizing waste carbon fiber, preparation method thereof, and stitched felt preparation device

Abstract

The invention discloses a stitched felt prepared by utilizing waste carbon fiber, a preparation method thereof, and a stitched felt preparation device. The stitched felt prepared by utilizing the waste carbon fiber comprises a waste fiber layer and yarns for stitching the waste fiber layer as the whole, the waste fiber layer is formed by uniformly laying the waste carbon fiber, carbon fibers and waste aramid fibers; the length of each of the aramid fiber and the waste aramid fiber is 6-9 cm, and the diameter is 5-15 microns; the length of each of the waste carbon fiber and the carbon fiber is4-8cm, and the diameter is 5-8 microns; the yarn is polyester yarn, and the diameter of the polyester yarn is 50-150D. The stitched felt preparation device utilizing the waste carbon fiber comprises achopping machine, a homogenizing device, a uniform lapper, an airflow lapper, a stitch-bonding machine, and a winding machine. The stitched felt prepared by utilizing the waste carbon fiber is good in uniformity, high in strength, and long in service life; and the characteristic that the waste carbon fiber is large in fragility is remedied through the compounding of the waste aramid fibers, and the stitched felt can be used for the electrostatic precipitators, environmentally-friendly equipment, wind-power blades, yin-yang dies, fiber reinforced plastic storage tanks, petroleum pipeline innerwalls and the like.

Description

technical field [0001] The invention relates to a stitch-bonded mat prepared by utilizing waste carbon fibers, a preparation method thereof and a stitch-bonded mat preparation device, belonging to the field of stitch-bonded mats. Background technique [0002] Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%. It is made of acrylic fiber and viscose fiber and is oxidized and carbonized at high temperature. With the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance, it is an excellent material for manufacturing high-tech equipment such as aerospace and aviation. [0003] When carbon fiber is prepared, a lot of harmful gases and substances will be produced, which requires high labor costs, low production efficiency, and high prices. [0004] Waste carbon fiber is an unavoidable industrial tailing produced during the production or use of carbon f...

[0003] When carbon fiber is prepared, a lot of harmful gases and substances will be produced, which requires high labor costs, low production efficiency, and high prices

[0004] Waste carbon fiber is an unavoidable industrial tailing produced during the production or use of carbon fiber. Since waste carbon fiber is easy to agglomerate, difficult to disperse, and poor in uniformity, it has always been treated by land deep burial, but this will cause serious damage to the land. Serious pollution, resulting in a large waste of land resources
