For example, collecting oily substances in wastewater for purifying industrial wastewater, collecting oil spilled to the sea or a river, and the like. Various types of oily substance adsorbents are known for various purposes. There are various forms such as a non-woven fabric, a cotton-like material, a tape-like material, a material obtained by binding them to a rope-like member, and a material using a mesh-like material as an oil fence.

し、吸着効率上問題がある。[0003] When recovering oily substances flowing out into rivers, seas and the like where water flows, it is difficult to recover a flat material, for example, a square nonwoven-shaped oil-adsorbing mat.
In addition, the so-called universal flag-type oil-absorbing material in which a flat oil-absorbing mat is tied to a rope-shaped member, creates a gap between the mats due to the mat being overlapped or broken, from which oil can pass or trash in the water. The adsorption ability is reduced by picking up, and there is a problem in the adsorption efficiency.

A particularly preferred thickness is from 1 μm to 1 mm. The width of the ribbon is preferably about 1 μm to 200 mm. If the width is too large, the amount of adsorption and the retention of adsorbed oil will decrease, and if it is too small, there is a problem in strength. Note that the ribbon-like material does not necessarily have to be flat, and may have a shape that is squeezed or partially twisted.

ることが好ましい。The length of the above-mentioned fiber or ribbon-like material is preferably about 0.5 to 5 m for river use. If the length is shorter than this, a sufficient amount of fibers cannot be obtained, and the adsorption amount and the adsorption efficiency are inferior. If the length is longer than this, there is no particular problem in terms of the adsorption amount and the adsorption efficiency, but it becomes difficult to handle at the time of installation on the water surface and recovery after adsorption. More preferably, it is about 1 to 2 m. Further, when the oily substance floating on the seawater surface is collected by a ship equipped with a collecting device, it is preferably about 0.5 to 100 m, particularly about 1 to 50 m.

用できる。As the oily substance adsorbent for the flowing water surface, one having one end bound to a rope-like member is preferable. The material and the shape of the rope-shaped member are not particularly limited. Any type such as a rope twisted, a cage type rope, and a rope having excellent strength such as a rope for a seat belt can be used.

ことができる。When a thermoplastic resin having oil-adsorbing ability, particularly a fibrous resin, is used, it has an oil-adsorbing effect and is a preferred embodiment. Further, the cage rope is a preferred embodiment in terms of handling because both ends have a shape that can be easily connected to a fixed object such as a pile, and are hard to be detached from the fixed object.
The length of the rope-shaped member can be selected according to the use scene.

There is no particular limitation. This is because the weight can be adjusted by the fiber diameter or the thickness and width of the ribbon-like material, the binding interval to the rope-like member, and the like. The binding interval is also not particularly limited, but if it is extremely wide, the adsorption efficiency becomes poor. As the oily substance adsorbent of the present invention, 5 to 20 fibers or ribbons (about 30 to 900 g in total) having a length of 1 to 100 m are bundled to form a fiber bundle or a ribbon, and this is attached to a cage rope. An example in which 50 to 100 bundles are bound at an interval of 5 to 10 cm is exemplified.

等に比して、油吸着量及び吸着油保持率に優れている。The oily substance adsorbent of the present invention has a particularly excellent effect on the sea surface of flowing water. Oil adsorbent of the present invention,
By being composed of a fiber bundle or a ribbon-like bundle,
It is supple and has excellent adhesion to the water surface, and it is possible to minimize the recovery loss from the gap between the overlapping portions such as a nonwoven fabric. In addition, rivers, oily substances floating on the water surface or the sea surface with a flow of seawater, etc., may sometimes dive slightly into the water from the water surface or the sea surface, but the oily substance adsorbent of the present invention has a certain degree of flow in the flowing water direction. It has a length and can be recovered when the oily substance that once dives into water floats again on the surface of the water or sea. Furthermore, since it is composed of a fiber bundle having a constant fiber diameter, the oil adsorption amount and the adsorbed oil retention rate are superior to that of a tape-like material or the like.
