Melt nano fiber super-high-efficiency oil absorbent cotton

Abstract

The invention discloses a melt nano fiber super-high-efficiency oil absorbent cotton. The melt nano fiber super-high-efficiency oil absorbent cotton mainly comprises porous cotton cloth layers, oriented nano fiber oil absorbing layers, and a nano fiber oil storage layer; the porous cotton cloth layers are arranged on the outermost layers; the oriented nano fiber oil absorbing layers and the nano fiber oil storage layer are arranged and combined in different sequences; the external surface of each oriented nano fiber oil absorbing layer is coated by the corresponding porous cotton cloth layer firmly, winkles on the external layers of the melt nano fiber super-high-efficiency oil absorbent cotton are formed by the porous cotton cloth layers and the oriented nano fiber oil absorbing layers; the porous cotton cloth layers and the oriented nano fiber oil absorbing layers are relatively thin; the nano fiber oil storage layer is arranged on the internal surfaces of the two oriented nano fiber oil absorbing layers; each of the two surfaces of the nano fiber oil storage layer and the corresponding surface of the oriented nano fiber oil absorbing are contacted with and embedded into each other. According to the melt nano fiber super-high-efficiency oil absorbent cotton, the porous cotton cloth layers with elasticity are taken as the outermost layers, and winkle surfaces are formed by the porous cotton cloth layers with the oriented nano fiber oil absorbing layers, so that the contact area of oriented oil absorbing fiber with oil stain is increased effectively; oil absorbed by the melt nano fiber super-high-efficiency oil absorbent cotton can be recycled via squeezing the melt nano fiber super-high-efficiency oil absorbent cotton, and oil stain absorption rate is maintained.

Description

technical field [0001] The invention relates to an ultra-efficient oil-absorbing cotton, in particular to a melt nanofiber ultra-efficient oil-absorbing cotton, which belongs to the field of oil pollution treatment. Background technique [0002] With the sharp increase in the demand and utilization of oil products in society, the pollution caused by various oil products is also on the rise. This pollution not only reduces the utilization rate of oil products, but more importantly threatens human health, pollutes the environment, and destroys ecological balance. Therefore, the recovery and treatment of oil pollution is a major problem that must be solved. At present, there are three main methods for removing oil stains: dispersion method, coagulation method and adsorption method. The dispersion method is inefficient and toxic, and has a narrow application area; the coagulation method requires secondary recovery and cannot be reused, and the cost of use is high; while the ad...
