Abstract

The invention discloses a static-resistant high-density oil absorbing cotton. The oil absorbing cotton comprises a PE leakage-resistant layer and an oil absorbing layer. The PE leakage-resistant layer is compounded and fixed along the periphery of the oil absorbing layer; the oil absorbing layer is formed on the surface of the PE leakage-resistant layer, and the oil absorbing layer is formed in the mode that filaments formed by oil absorbing polymeric fibers and heat bonding fibers are subjected to warp mosaic weaving or warp-weft mosaic weaving to form a fiber web, and the fiber web is acupunctured; the content of high shrinkage fibers in the filaments is 10%-45%, the diameter ratio of the oil absorbing polymeric fibers to the high shrinkage fibers is 1:1-3:2, and the length of the high shrinkage fibers is 2 or more times that of the oil absorbing polymeric fibers. According to the oil absorbing cotton, as the acupuncture production technology is combined, good static resistance and the good oil absorbing performance are achieved, the strength, the toughness and the abrasive resistance of the oil absorbing cotton are improved, and the oil absorbing cotton is free of hair slipping, layering and falling.

Description

technical field [0001] The invention relates to the field of oil stain treatment, in particular to an antistatic high-density 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 is ...
