Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a carrier for inorganic or organic liquids such as water, oil, alcohol, etc. That is, the present invention utilizes capillary phenomenon to provide a conveying body that lifts the liquid to a high place against gravity or conveys it laterally, and this conveying body uses the power of a pump etc. Not only can liquids be conveyed over considerable distances without the use of liquids, but they can also be used as evaporation media to effectively evaporate liquids.

Specifically, it can be used for hydroponic cultivation, as a lamp wick, as a drain material, or for evaporating condensed water generated in refrigerators, freezer cases, refrigerators, etc. into the atmosphere, or for humidity control.

(Prior Art) Conventionally, in order to transport inorganic or organic liquids, it is necessary to use human power or various types of power, and transport costs are indispensable. On the other hand, capillary action has been used to transport liquids or lift liquids to high places. For example, lamp wicks, drain materials, etc. However, with conventional means, for example, in the case of water, it is extremely difficult to lift it to a height of 15 cm from the water surface. For example, cotton fabric (poplin, 30 ^s cotton yarn, thread density 180-206 threads/ ^inch2 ) can only absorb water up to a maximum height of about 7-8 cm. Although it is possible to use a web made of water-absorbing resin fibers, the resin swells and closes the gaps, resulting in a rise of only 7 to 8 cm.

(Problems to be Solved by the Invention) In view of the above-mentioned drawbacks of the conventional carrier, it is an object of the present invention to provide a carrier that can lift liquid to an extremely high place by capillary action.

The present applicant has previously proposed, as an excellent liquid carrier, a fiber assembly in which liquidphobic fibers are arranged substantially in one direction and integrated, and a fiber assembly in which liquidphobic fibers are arranged in a substantially random direction and integrated. We provided a laminate in which these were laminated. However, subsequent research revealed that fiber aggregates made by arranging lyophobic fibers substantially in one direction were treated with a lyophilic process to make them durable against the liquid, and were found to be excellent liquid carriers. We discovered this and came up with this idea.

(Means for Solving the Problems) Therefore, the present invention provides a material that is durable against the liquid on the surface of the constituent fibers of a fiber assembly in which liquidphobic fibers are arranged substantially in one direction and integrated. This is a liquid carrier characterized by being coated with a lyophilic processing agent.

Here, lyophobic fibers are fibers that do not substantially chemically or physicochemically interact with the liquid being transported, that is, fibers that do not cause a chemical reaction with the liquid being transported, Fibers that do not substantially dissolve or swell.For example, hydrophobic fibers such as polyester, polyamide, polyethylene, polyvinyl chloride, etc. are used when exposed to water, and when exposed to oil such as petroleum. For these, oleophobic fibers, specifically fibers such as cotton, rayon, and animal hair, are used. The above-mentioned fibers may be either long fibers or short fibers. The thickness of the fiber is preferably 0.1 to 300D, and the cross-sectional shape of the fiber is circular.
It may be any of the odd shapes.

In addition, fiber aggregates that are substantially aligned in one direction and integrated include twisted yarns, spun yarns, or non-twisted yarns arranged in parallel, in which fibers are arranged in one direction and twisted together;
There are felts, non-woven fabrics, etc. that are woven or knitted, or that have fibers oriented in substantially the same direction. Non-twisted yarns, non-woven fabrics, etc. may be bonded with a binder to the extent that the gaps between the fibers are not largely blocked.

The treatment agent for applying the lyophilic finish must be durable. That is, it must not be one that will substantially dissolve or swell in the liquid being transported. For example, when the carrier liquid is water, a hydrophilic treatment agent such as a polyester fiber graft-polymerized with polyethylene glycol is used, and a polyamide fiber is treated with a hydrophilic treatment agent such as a polyamide graft-polymerized polyethylene glycol treatment agent. These adhere firmly to the surfaces of the constituent fibers. Alternatively, a chemically reactive substance such as a calcium chloride/methanol solution for polyamide may be applied to only the fiber surface to make it hydrophilic.

Examples of liquids to be transported include water, oil, various liquid fuels, and various solvents. Further, organic and inorganic solutes such as various salts, fertilizers, and drugs may be dissolved in these liquids.

Next, the present invention will be explained with reference to the drawings.
