1. Field of the Invention
The present invention relates to cloths, and more particularly to an absorptive cloth that is highly absorptive to stinky fluid.
2. Description of the Related Art
Regular cloths use the capillary effect of the fibers to guide attached water drops into the inside of the cloth body. This water absorbing speed is low. A water diffusion trace on the surface of the cloth body can be seen. When the body touched the water diffusion trace area, the user will feel cold and wet, i.e., uncomfortable.
In order to eliminate wet, sticky, and non-breathing problems, absorptive fibers and cloths are developed. These absorptive fibers are made by improving the hydrophilic property of hydrophobic fibers by means of one of the following two ways. The first way is to add hydrophilic polymers to fibers chemically. The second way is change the structure or cross section of the yarns, i.e., to form a porous and/or hollow structure in fibers during spinning, making the fibers absorptive and improving the hydrophilic property of the fibers. These methods improve the water absorbing speed of the fibers. These absorptive fibers are commonly used for making underwear, sports wear and shoe linings. However, absorbed water is still kept among hydrophobic fibers, causing the cloth wet and cold.
Further, the body of a person will expel stinky substances such as NH3 and H2S. As it is known that as NH3 and H2S cannot exist in air independently, and can easily be surrounded by water in air. The reaction equations are: as NH3+(H2O)xz,900 NH3(H2O)x; H2S+(H2O)x NH3(H2O)x. When the body expels NH3 and H2S, NH3 and H2S will soon be surrounded by water in air, establishing the aforesaid equations. Therefore, the best way to remove stinky smell from the body is to remove water that surrounds NH3 and H2S. However, commercially available cloths are not workable in this way.
The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide an absorptive cloth, which absorbs and diffuses water rapidly, keeping the cloth body dry.
To achieve this and other objects of the present invention, the absorptive cloth comprises a cloth body, which is comprised of an absorptive layer and a diffusion layer. The absorptive layer is made out of a fiber material containing nanobon and a hydrophilic absorptive material. The diffusion layer is made out of polyester, nylon, cotton or polypropylene fibers.
Referring to
According to a research made by Technical Department of Economic Affairs of Taiwan, bamboo nanobon has a super absorptive power, and the surface area of bamboo nanobon is about 3 times over an equal volume of wooden nanobon. Bamboo nanobon has a fine porous structure that absorbs and decomposes methyl alcohol, sulfide, nitride, benzene, and phenol.
According to a test made by Taiwan Textile Research Institute, ammonium was soon surrounded by water in air, thereby forming water drops, and the concentration of ammonium dropped naturally from 40 ppm to 28 ppm after 24 hours. However, after the use of an absorptive cloth made according to the present invention, the concentration of ammonium dropped drastically from 40 ppm to 3 ppm at either side of the absorptive cloth, i.e., the absorptive rate was as high as 89%. This test report approves the effectiveness of the present invention.
As indicated above, the porous structure of bamboo nanobon is highly absorptive to water. The invention uses the absorptive property of nanobon to enhance the absorptive power of the absorptive cloth. When water drops touched the surface of the absorptive cloth, water drops are immediately absorbed by bamboo nanobon in the absorptive layer. Further, the hydrophilic absorptive material such as sodium iron toumaline immediately guide the absorbed water to the diffusion layer that diffuse absorbed water outwards, enabling absorbed water to be evaporated. Therefore, the cloth body of the absorptive cloth can soon be kept in dry.
The absorptive cloth of the present invention is practical for making clothes. When the body expels ammonium, ammonium will soon be joined to water in air or the sweat expelled from the user's body, and the clothe made of the absorptive cloth of the present invention will soon absorb ammonium-contained water and sweat and diffuse absorbed ammonium-contained water and sweat in different directions toward the outside for enabling ammonium-contained water and sweat to be soon evaporated into the outside open air. Therefore, the clothes can be kept dry without smell.
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims
