DETAILED DESCRIPTION OF THE INVENTION

[0028] The aforementioned and further advantages and features of the present invention will be understood by reference to the description of the preferred embodiment. It shall be noted that the accompanying drawings of the embodiment have the components thereof illustrated based on a proportion for explanation but not subject to the actual component proportion.

[0029] Referring to FIG. 1 to FIG. 2, ultraviolet resistant fabric with temperature control function 100 provided by the present invention comprises a base material 10 and an aluminum film layer 20. The base material 10 is selected from a knit fabric/woven fabric which is woven by a plurality of interlaced warps and wefts, a non-woven fabric, or a composite fabric.

[0030] The base material 10 includes a concave-convex shaped first surface 11 and an opposite second surface 12.

[0031] The aluminum film layer 20 is formed on the first surface 11 through a manner of evaporation depositing or sputtering depositing process, wherein the weight of the aluminum film layer 20 ranges from 0.8 g/m.sup.2 to 1.8 g/m.sup.2, and the thickness of the aluminum film layer 20 is smaller than the thickness of the base material 10.

[0032] Therefore, with the surface of the base material 10 completely attached by the aluminum film layer 20, the base material 10 is allowed to direct a heat up from 1 to 4 Celsius degrees, achieving a temperature controlling effect, and the aluminum film layer 20 provides the base material 10 with an outstanding capability of resisting ultraviolet (UV-A, UV-B), wherein the blockage ratio is at least 95%. As shown by the appendix document 1, which is a test report of the sample in accordance with the present invention issued by Intertek Testing Services Taiwan Ltd., the fabric of the present invention actually shows an at least 95% ultraviolet (UV-A, UV-B) resistance capability.

[0033] Further, with the aluminum film layer 20 formed on the base material 10 through an evaporation or sputtering deposition, aluminum molecules are completely attached to fibers of the base material 10, such that the finished product does not affect the original texture handfeel of the base material 10, with the handfeel and breathability remained. Also, the aluminum film layer 20 and the base material 10 are highly combined, prevented from detachment, thus increasing the range of application of the finished product.

[0034] Referring to FIG. 3, which is another embodiment of the present invention, the present invention further includes a water repellent layer 30 combined to fibers of the combination of the first surface 11 and the aluminum film layer 20. Also, the water repellent layer 30 has an attachment face 31 disposed on one side thereof away from the base material 10, and the profile of the attachment face 31 approximately matches with the first surface 11, such that the aluminum film layer 20 is formed on the attachment face 31. In the embodiment, only the first surface 11 is provided with the water repellent layer 30 for illustration. Of course, the water repellent layer 30 is allowed to be formed on both surfaces of the base material 10.

[0035] Therefore, when the present invention is applied to the lining of the cloth (as shown by FIG. 4) or made into a beanie (as shown by FIG. 5) or other commodities, the water repellent layer 30 enhances the bonding strength between the aluminum molecules and the fibers, such that the heat directing function and the ultraviolet (UV-A, UV-B) resisting function are maintained after the product being washed with water.

[0036] Next, referring to FIG. 6, a manufacturing method of an ultraviolet resistant fabric with temperature control function 100 is provided by the present invention, comprising following steps:

[0037] providing a base material 10;

[0038] drying, the base material 10 being dried to remove moisture therefrom; in the present invention, the drying step is allowed to be carried out through an oven or a setting machine for drying the base material 10;

[0039] rough processing, treating the first surface 11 with high voltage ions through a plasma machine, so as to increase a friction coefficient of the first surface;

[0040] vacuum metalizing, forming an aluminum film layer 20 on the first surface 11 of the base material 10; wherein before the formation of the aluminum film layer 20, the processing environment is vacuumed, so as to carry out the vacuum metalizing process with a strength larger than 110.sup.4 Pa. In the present invention, the vacuum metalizing process is carried out through an evaporation or sputtering deposition. If the evaporation depositing process is chosen, the evaporation depositing is carried out in a speed ranging from 1.5 m-3 m/second. If the sputtering depositing process is chosen, the sputtering depositing is carried out in a speed ranging from 0.5 m-1 m/2 seconds.

[0041] No matter whichever the evaporation deposition or sputtering deposition is chosen to carry out the metalizing operation, based on the fact that the first surface 11 of the base material 10 is treated with high voltage ions through a plasma machine before the metalizing operation, the friction coefficient of the first surface 11 is increased, such that the target of aluminum metal is allowed to be stably attached to the base material 10.

[0042] Furthermore, before the drying step, the base material 10 is allowed to be dipped in a water repellent chemical, so as to form the water repellent layer 30 on the first surface 11 and the second surface 12, respectively, with the aluminum film layer 20 formed on fibers with the water repellent layer 30 on the first surface 11. Of course, another aluminum film layer 20 is able to be formed on the second surface 12 according to different demand.

[0043] With the aforementioned manufacturing method, the base material 10 acquired a certain degree of heat directing and ultraviolet resisting capability. Also, with subsequent processes, such as being applied to PU coating or lamination with PU, TPU, or PVC membrane, the product is thereby provided with water proof function and improved breathability. Also, the present invention is able to be normally bonded with other knit/woven fabrics or non-woven fabrics for increases the range of application of the finished product.

[0044] Although particular embodiments of the invention have 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.
