Description

  The present invention relates to a connecting mat used for oil removal.

  Conventionally, petroleum, which has been widely used as a power source, chemical raw material, etc., is a liquid when spilled in the ocean due to a ship sunk accident or the like, and is thus liable to diffuse and cause ocean pollution. In order to remove the contaminated oil that causes such marine pollution, a method of scooping out the contaminated oil on the surface using a shark or the like is known, but it has a disadvantage of poor efficiency. There is also a method of pouring and emulsifying a surfactant in a place where the contaminated oil is present, but there is a risk of contamination by the surfactant rather than removing the contaminated oil itself.

  In addition, there is a method to absorb the contaminated oil by surrounding it with an oil fence to prevent the contaminated oil from spreading and throwing an oil-absorbing fiber mat such as polypropylene to absorb the contaminated oil. There are drawbacks.

As a prior art regarding an oil absorption mat, there exist the following techniques, for example.
Spring-type throwing characterized by the provision of a resilient spring material along the periphery of the oil-absorbing mat for the purpose of improving throwing distance and controllability by allowing it to be thrown while folded A technique related to an oil absorbing mat for use is disclosed (Patent Document 1).
A mat-like oil collecting material which is a self-bonded fibrous structure made of polypropylene fibers, and is formed by folding and laminating a long sheet in which the polypropylene fibers are arranged in the longitudinal direction to a width of 5 to 50 mm, and laminating them in layers. Is known (Patent Document 2).

However, these methods have a defect that does not take into account recovery after oil absorption, and improvement is desired.

The object of the present invention is to develop a connecting mat that can effectively remove leaked contaminated oil without being affected by wind and waves.

The inventor of the present invention has arrived at the present invention as a result of diligent research on a method for removing leaked contaminated oil. That is,
In the present invention, a connecting mat is used in which a plurality of mats are connected by a connecting material made of a string having a ring, a nonwoven fabric or a knitted fabric. In use, according to the amount and area of the leaked contaminated oil, the required amount of the connecting mat can be cut by cutting the connecting material, so that the required amount can be used. It can be easily recovered by connecting the rings at both ends of the connecting mat together with a string. Based on these findings, the present invention has been reached.

That is, the present invention
(1) In a connecting mat in which a plurality of mats made of organic fibers are connected by a connecting material,
The connecting material is a string having a ring, a nonwoven fabric or a knitted fabric,
(2) In the connecting mat of (1),
The connecting material is a string, a nonwoven fabric or a knitted fabric in which a ring is formed by connecting two points of the structure constituting the connecting material to each other,
(3) In the connection mats of (1) to (2), the connection mats are connected at one to four places of the mats constituting the connection mat by a connecting material,
(4) In (1) to (3), the mat constituting the connecting mat is a nonwoven fabric or a knitted fabric,
(5) In (1) to (4), the mat constituting the connection mat has a structure in which a plurality of nonwoven fabrics or knitted fabrics are combined using a needle punch.
(6) In (1) to (4), the organic fiber is cotton, cellulose acetate fiber, polyamide fiber, polyester fiber, acrylic fiber, polyolefin fiber,
(7) In (1) to (4), the organic fiber is a reuse fiber such as cotton, cellulose acetate fiber, polyamide fiber, polyester fiber, acrylic fiber, or polyolefin fiber.

In the present invention, the connecting material is a string, a non-woven fabric or a knitted fabric in which a ring is formed by connecting two points of the connecting material structure to each other. It is preferable that two or more such rings are formed per mat and mat connection portion. And when connecting a mat and a mat with another connecting material, when connecting two mats, one connecting material connects one end of a mat. When connecting the mats linearly, two connecting members may connect one end and the other end of the mat, or four connecting members may connect the vicinity of the ends of the four sides of the mat. In addition, when connecting in a some position, the connection material may form one connection material in a row, and may be divided between the places to connect.
When the oil leaks and is contaminated, the connecting material is cut between the rings of the connecting material with a knife, scissors, sickle, etc. in order to take out a necessary amount according to the degree of contamination. Oil is absorbed by throwing the cut connecting mat into a place where the oil leaks and is contaminated.

Since the connecting mat is in a partially connected state, it is not dissipated by waves and winds. Since there are rings at both ends of the connection mat, the connection mat after use can be easily collected by passing a string or the like through the ring and pulling it toward the hand.

In the present invention, usable organic fibers include cotton, cellulose acetate fiber, acrylic fiber, polyamide fiber, polyester fiber, and polypropylene fiber. This is because these fibers can be easily obtained. The thickness of these fibers is preferably in the range of 1 to 20 denier. This is because the thickness within this range can be easily obtained as a fiber for clothing or as a fiber for indoor rugs such as carpets. In this case, it is also possible to use reused fibers from which dirt has been removed after having already been used for carpets, gloves and the like.

In the present invention, in the case of fibers having a specific gravity greater than the specific gravity of water, such as cotton, cellulose acetate fiber, acrylic fiber, and polyester fiber, if water permeates between the fibers, the fiber sinks into the water. In order to prevent this, the fiber needs to be water-repellent to prevent water penetration.
As such a water-repellent agent, a conventionally known water-repellent agent using a silicon resin can be used.

In the present invention, the mat means a non-woven fabric, woven fabric or knitted fabric formed by a relatively thick glue needle punch or the like, but a non-woven fabric is preferred from the viewpoint of economy and performance.

  In the present invention, the connecting material used for connecting the connecting mats is a string, a nonwoven fabric or a knitted fabric. The connecting material forms a ring by connecting two points of the connecting material structure to each other. At two points of the connecting material structure, for example, a sewing thread is used to sew together, thereby forming a ring between the stitched structures.

In the present invention, the mat forming the connection mat may be a mat made of a single non-work cloth or a knitted fabric, or a mat formed by combining a plurality of un-work cloths or a knitted fabric. Examples of a method of combining a plurality of unemployed fabrics and knitted fabrics include a method of sewing them together using a sewing thread.

In the present invention, the size of the mat used for the connecting mat is preferably about 10 to 80 centimeters. If it is smaller than 10 centimeters, there is a high possibility that seawater will overflow due to waves, and if it is larger than 80 centimeters, it is inconvenient to handle.

In the present invention, as a method of forming a ring, after attaching a connecting material, a method of forming a ring by connecting two points of the connecting material structure to each other, and a method of attaching a connecting material after forming a ring in advance There is.

A mat having a thickness of 4.3 mm, a width of 55 centimeters, and a length of 55 centimeters using a recycled fiber of 50% by weight of cotton derived from carpet and work gloves and 50% by weight of acrylic fiber / polyester fiber is prepared.
As a mat connecting material, an elongate knitted fabric having a width of 3 cm and a thickness of 3 mm is prepared.

FIG. 1 is a plan view of a connecting mat 5 created by connecting a plurality of mats 1 with a connecting member 2 having a ring 3. Note that the connecting members 2 that connect the plurality of mats are connected to each other.
FIG. 2 is a cross-sectional view of a connecting mat 5 created by connecting a plurality of mats 1 with a connecting member 2 having a ring 3.
The connecting material 2 having the ring 3 in FIG. 1 can create the connecting material 2 having the ring 3 by connecting two points of the connecting material structure to each other. In order to create the connecting mat 5, the connecting members 2 are stitched in parallel to one side of the mat 1, and another mat 1 is connected with a gap between the mats 1.
Next, it is possible to form the ring 3 on the connecting material 2 of the connecting mat 5 having the ring 3 by connecting two points of the connecting material structure of the connecting material 2 to each other.
Further, as shown in FIG. 3, two mats 1 can be used as mats, and the mats 1 can be connected in the vicinity of two sides facing each other as shown in FIG.
The connecting mat 5 of the present invention can be easily separated by cutting the connecting material 2 connecting the mat 1, and can be reconnected by the connecting string 4 as shown in FIG. is there.
