BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a manufacturing method for weaved layer, and more particularly, to a manufacturing method for non-powered energy layer.
2. Description of Related Art
In busy modern life, people desire to have a good sleep quality for fully relaxing their bodies and adjusting physical functions after working hard for one day; for this reason, people make more and more requirements on functionalities of quilt covers, bedquilts, blankets, and mattress.
Please refer to FIG. 1, which illustrates a stereo view of a traditional bedquilt. As shown in FIG. 1, the traditional bedquilt 1′ includes an outer cotton sheet 11′ and an inner warming layer 12′, wherein the single outer cotton sheet 11′ can used as a cool quilt for summer; On the contrary, as cold winter is coming, the bedquilt 1′ can be used as a warm quilt by way of disposing the inner warming layer 12′ inside the outer cotton sheet 11′. Although such traditional bedquilt 1′ is widely used around the world, the heat retention of the traditional bedquilt 1′ is still adequate for the old people or the people living in high latitude regions.
Thus, according to the traditional bedquilt 1′ includes less heat retention and functionality, some quilt manufacturers are mixing far infrared powder into the inner warming layer 12′. The far infrared powder is able to emit a far-infrared ray, which may excite man skin, and then make the microvascular dilation and promote the blood circulation and metabolism of man body. Therefore, when a user is covered with the bedquilt having the far infrared powder, the user would get high body temperature result from the promotion of blood circulation and metabolism. Generally, far infrared materials are divided into: (1) natural ores having far-infrared radiation energy; and (2) far infrared ceramic sintered at high temperature. In which, the far-infrared radiation energy emitted by the natural ore is un-uniform, but the far-infrared radiation energy of the ceramic can be modulated by changing the proportion of raw materials thereof.
Besides the far infrared powder, quilt manufacturers also add a so-called active layer into the bedquilt, wherein the active layer is made by anion-synthetic fiber, electromagnetic chemical fiber, nano far-infrared fiber, or bamboo charcoal fiber. The main function of the active layer is to activate the body cells for enhancing the immune system, moreover, some active layers further includes the characters of less cotton batting, anti dust-mite, anti-bacterial, and good temperature resistance.
However, whatever the bedquilt having the far infrared powder or the active layer, it cannot adapted for covering the man body having sensitive skin. When the man having sensitive skin is covered with the bedquilt having the far infrared powder or the active layer, the sensitive skin would produce swelling or itching.
Accordingly, in view of the traditional bedquilt and the bedquilt having the far infrared powder or the active layer still have shortcomings and drawbacks, the inventor of the present application has made great efforts to make inventive research thereon and eventually provided a manufacturing method for non-powered energy layer.

DETAILED DESCRIPTION OF THE INVENTION
To more clearly describe a manufacturing method for non-powered energy layer according to the present invention, embodiments of the present invention will be described in detail with reference to the attached drawings hereinafter.
Please refer to FIG. 2, which illustrates a flow chart of the manufacturing method for non-powered energy layer according to the present invention; and please simultaneously refer to FIG. 3A to FIG. 3C, there are shown schematic process diagrams of the non-powered energy layer. The manufacturing method mainly includes four steps of:
As shown in FIG. 2, the manufacturing method is firstly proceeded to step (S01), providing a powdered metal mixture mixed by a powdered titanium material, a powdered germanium material, a powdered zinc material, a powdered oxide material, and a powdered carbide material; wherein the concentrations for the powdered titanium material, the powdered germanium material, and the powdered zinc material are respectively ranged between 15 wt %-20 wt %, 0.15 wt %-0.2 wt %, and 0.05 wt %-0.1 wt %. Next, as shown in FIG. 2 and FIG. 3A, the powdered metal mixture 20 is then covered and enclosed by a polymer 10 through step (S02); wherein the polymer 10 is mixed with a silica material of at least 50 wt %, and the chemical structure of the polymer is presented by following chemical formula 1:




In the chemical structure presented by chemical formula 1, n ranges from 50 to 100. Continuously, the method flow is proceeded to step (S03), fabricating the end-product of the step (S02) to a plurality of non-powered energy granules 30 (as shown in FIG. 3A). As shown in FIG. 2 and FIG. 3B, after step (S03) is finished, the flow is next proceeded to step (S04) for executing a spinning process so as to draw the non-powered energy granules to a plurality of non-powered energy silk strings 40. Please refer to FIG. 4, which illustrates a front sectional view of the non-powered energy silk string. As shown in FIG. 4, the non-powered energy silk string 40 is hollow with an outer layer of the polymer 10 and an inner layer of the powdered metal mixture 20.
After obtained the non-powered energy silk string 40, it needs to determine whether the non-powered energy silk strings contains a titanium content of 12.9 wt %-16.7 wt %, a germanium content of 0.11 wt %-0.16 wt %, and a zinc content of 0.06 wt %-0.09 wt %, so that step (S05) is executed subsequent to the step (SO4). Please refer to FIG. 5A and FIG. 5B, there are shown ICP-AES testing result tables for the non-powered energy silk strings. As FIG. 5A shows, sample 1 of the non-powered energy silk strings 40 is dissolved in acid solution, and then the content of the testing items contended by the non-powered energy silk strings 40 are analyzed by using the inductively coupled plasma-atomic emission spectrometer (ICP-AES). Therefore, the testing results reveal that the sample 1 of the non-powered energy silk strings 40 contains the titanium content of 12.9 wt %, the germanium content of 0.16 wt %, and the zinc content of 0.064 wt %. Herein, it needs further explain that the unit of mg/kg means ppm (part per million), and 1000 mg/kg is equal to 0.1 wt %.

Therefore, the testing results reveal that the sample 1 of the non-powered energy silk strings 40 contains the titanium content of 16.7 wt %, the germanium content of 0.11 wt %, and the zinc content of 0.09 wt %. In the present invention, the trace amount of zinc content is helpful to modulate the wavelength of the far-infrared ray emitted by the non-powered energy silk strings 40 to be ranged between 4 μm to 14 μm. Moreover, the powdered carbide content and the powdered oxide content are used for increasing the emissivity of the far-infrared ray.

Therefore, when a user is covered with the bedquilt 51 using the non-powered energy layer 50 as the inner warming layer, far-infrared ray emitted by the non-powered energy layer 50 would excite the user's skin, so as to make the microvascular dilation and promote the blood circulation and metabolism of user body. Furthermore, in the present invention, the material of the powdered carbide can be TaC, ZrC, SiC, or a mixture made by any two aforesaid materials.
