The fabric with carbon nanotube fibers of the present invention and the manufacturing method thereof will be described below.
-
FIG. 1 is a manufacturing flow chart of a fabric with carbon nanotube fibers according to an embodiment of the present invention. Referring toFIG. 1 , instep 100, carbon nanotubes are grown on a substrate. The substrate may be a silicon oxide substrate. The method of growing carbon nanotubes is, for example, a chemical vapor deposition (CVD) process. During the growth of carbon nanotubes, the parameters of the deposition process may be adjusted to obtain carbon nanotubes with the required diameter and the required growth density. In addition, before performing the deposition process, a layer of metal particles may be formed on the substrate as a catalytic layer. The material of the metal particles is, for example, iron, nickel, cobalt, aluminum or a combination thereof. By controlling the distribution of metal particles, the physical properties such as the diameter and growth density of the formed carbon nanotubes may be further adjusted. - In addition, during the growth of the carbon nanotubes, a doping treatment may be optionally performed in-situ. For example, during the growth of the carbon nanotubes, a nitrogen doping or a boron doping may be performed in-situ to adjust the conductivity type of the formed carbon nanotubes. When the nitrogen doping is performed in-situ during the growth of the carbon nanotubes, N-type carbon nanotubes may be formed, and when the boron doping is performed in-situ during the growth of the carbon nanotubes, P-type carbon nanotubes may be formed.
- Next, in
step 102, a metal layer may be optionally formed on the surfaces of the formed carbon nanotubes. The method of forming the metal layer is, for example, an electroplating process. The metal layer may be a gold layer, a copper layer, a silver layer, an iron layer, or a combination thereof. After the metal layer is formed on the surfaces of the carbon nanotubes, the carbon nanotubes may have the characteristics of the metal layer, and therefore, the fabric formed subsequently may also have the characteristics of the metal layer. Of course, depending on actual needs, step 102 may also be omitted. - Then, in
step 104, a drawing process is performed on the formed carbon nanotubes to form carbon nanotube fibers. The steps of the drawing process includes, for example, using a tape to stick a corner of the substrate on which carbon nanotubes are formed and pulling it out in a direction perpendicular to the growth direction of the carbon nanotubes. At this time, the carbon nanotubes on the substrate are arranged in a filamentary manner due to Van Der Waal force, forming carbon nanotube fibers. - In addition, in
step 104, depending on actual needs, carbon nanotubes may be optionally pre-mixed with natural fiber materials, and then subjected to the drawing process. In this way, carbon nanotube fibers with natural fiber characteristics may be formed. The natural fiber material may be cotton, linen, wool, rabbit hair, silk, tencel or coffee. For example, when carbon nanotubes are mixed with cotton, because the cotton has electrical conductivity (about 800 Scm2/g), abrasion resistance and antistatic properties, the carbon nanotube fibers formed by the drawing process may also have the above characteristics. The diameter of the formed carbon nanotube fibers is, for example, between 5 nm and 100 nm. In addition, depending on the growth density of carbon nanotubes, the density of the formed carbon nanotube fibers is, for example, between 0.5 g/cm3 and 1.8 g/cm3. - Next, in
step 106, the formed carbon nanotube fibers are subjected to a spinning process to form carbon nanotube fiber yarns. At this time, the carbon nanotube fiber yarns may have various required characteristics depending on the components in the previously formed carbon nanotube fibers, which is not limited in the present invention. The spinning process is well known to those skilled in the art, and will not be further described here. In addition, the formed carbon nanotube fiber yarns have a required diameter depending on the actual situation, which is not limited in the present invention. - After that, in
step 108, the formed carbon nanotube fiber yarns are woven to form the fabric of the present invention. Depending on actual needs, only the carbon nanotube fiber yarns of the present invention may be used to manufacture the fabric of the present invention. Alternatively, the carbon nanotube fiber yarns of the present invention and any existing yarns may be used together to manufacture the fabric of the present invention. This will be described below. - In the case of using only the carbon nanotube fiber yarns of the present invention to manufacture a fabric, the carbon nanotube fiber yarns of the present invention are used as warp yarns and weft yarns and a weaving process is performed, such that warp yarns and weft yarns are interwoven to form a fabric. In other words, the material of warp yarns is the same as that of weft yarns. As shown in
FIG. 2 , the carbon nanotube fiber yarns of the present invention are used aswarp yarns 200 andweft yarns 202, respectively, and thewarp yarns 200 andweft yarns 202 are interwoven to form afabric 10. Depending on the actual application, thefabric 10 may have various weaving densities, which is not limited in the present invention. - Since the entire of the
fabric 10 is woven by using the carbon nanotube fiber yarns of the present invention, thefabric 10 has exactly the same characteristics as the carbon nanotube fiber yarns of the present invention. For example, depending on the characteristics of the carbon nanotube fiber yarns itself,fabric 10 made of only the carbon nanotube fiber yarns of the present invention may have good mechanical strength, stain resistance, ductility, conductivity, hydrophobicity, abrasion resistance, antistatic, and UV resistance. In addition, since carbon nanotubes are artificially synthesized material, they have lower microbial adhesion and inertness compared with natural material. Therefore, the toxin content infabric 10 may be lower than that of natural material, and thefabric 10 is not easy to react with external substances and cause deterioration. - In the case of using the carbon nanotube fiber yarns of the present invention and any existing yarns to manufacture a fabric, the carbon nanotube fiber yarns of the present invention are used as one of warp yarns and weft yarns and the any existing yarns are used as the other of warp yarns and weft yarns, and a weaving process is performed, such that warp yarns and weft yarns are interwoven to form a fabric. In other words, the material of warp yarns is different from that of weft yarns. As shown in
FIG. 3 , the carbon nanotube fiber yarns of the present invention are used as thewarp yarns 200 and the any existing yarns are used as theweft yarns 204, and thewarp yarns 200 and theweft yarns 204 are interwoven to form thefabric 20. Depending on the actual application, thefabric 20 may have various weaving densities, which is not limited in the present invention.Weft yarns 204 may be cotton fiber yarn, linen fiber yarn, wool fiber yarn, rabbit hair fiber yarn, silk fiber yarn, tencel fiber yarn, coffee fiber yarn, nylon fiber yarn, polyester fiber yarn, rayon fiber yarn, acrylic fiber yarn or polyurethane fiber yarn. In addition, in this case, the diameter of the fibers constituting theweft yarns 204 is, for example, between 10 nm and 106 nm. - Since the
fabric 20 is woven by using the carbon nanotube fiber yarns of the present invention and the any existing yarns, thefabric 20 may have the same characteristics as thefabric 10 and also have characteristics as the any existing yarns. Therefore, thefabric 20 may better meet the actual needs and have a wider range of applications. To put it another way, compared with the general fabrics on the market, in addition to their effects, thefabric 20 may also have the effect brought by the carbon nanotube fiber yarns of the present invention. - It will be apparent to those skilled in the art that various modifications and variations may be made to the disclosed embodiments without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the disclosure covers modifications and variations provided that they fall within the scope of the following claims and their equivalents.
