Embodiment 1

[0024] The present invention provides an antistatic high-toughness oil-absorbing cotton, which is characterized in that the oil-absorbing cotton includes a PE leak-proof layer 1 and an oil-absorbing layer 2, and the PE leak-proof layer 1 is compounded and fixed along the periphery of the oil-absorbing layer 2. The oil-absorbing layer 2 is formed on the surface of the PE leak-proof layer 1, the material of the oil-absorbing layer 2 is a polymer fiber, the surface and the inside of the oil-absorbing layer 2 are sponge-like, and the surface of the oil-absorbing cotton has a tapered hole 3. The oil-absorbing layer is produced by a needle-punching process, which specifically includes weaving long filaments formed of oil-absorbing polymer fibers and thermally bonded fibers together in the warp direction or weaving conductive fibers in the warp and weft directions to form a fiber web. After the fiber web is needled and then hot-rolled, the content of thermally bonded fibers in the fil...

Abstract

The invention discloses anti-static and high-toughness oil absorbent roll. The oil absorbent roll comprises a PE leakage-proof layer and an oil sorbent layer. The PE leakage-proof layer is compounded and fixed along the periphery of the oil sorbent layer. The oil sorbent layer is formed on the surface of the PE leakage-proof layer. The surface and the inside of the oil sorbent layer are in a spongy shape. Taper holes are formed in the surface of the oil absorbent roll. The oil sorbent layer forms a fiber web through warp direction embedding or warp direction and weft direction embedding weaving of filament formed by oil sorbent high molecular fiber and heat bonding fiber, needling on the fiber web is performed, the content of the heat bonding fiber in the filament is 5%-25%, the diameter ratio of the oil sorbent high molecular fiber to the heat bonding fiber is 5:1-7:1, and the length of the heat bonding fiber is below 1 / 5 that of the oil sorbent high molecular fiber. The anti-static and high-toughness oil absorbent roll effectively avoids secondary pollution caused by oil leakage because of compression in the utilization process and has anti-static performance. The taper holes are formed in the surface of the oil sorbent layer, so that the oil sorbent rate is improved greatly, and blocking conditions on the surface of the oil sorbent layer do not occur easily.

Description

technical field [0001] The invention relates to the field of oil stain treatment, in particular to an antistatic high-toughness oil-absorbing cotton. Background technique [0002] When an oil spill occurs on the sea surface, or when an oil spill occurs in a factory and pollutes the nearby river, there are generally three methods to remove the oil pollution. One is the dispersion method, that is, the oil dispersant is used to break the oil film, making it into particles and dispersing into the water phase. In the middle, the oil dispersant accelerates the micronization process of the oil, makes the oil diffuse in the vertical direction, and does not form an oil film on the surface of the water body, so that it does not adhere to ships, reefs and coastlines. The use of dispersants increases the surface area of ​​the oil and accelerates the biodegradation of the oil. However, dispersants are often highly toxic, and when the oil spill area is large, the oil removal efficiency i...
