Because the temperature difference is not so high between high temperature airflow 26 ′ and 24 ′ and the inlet of airflow 210 ′ and the outlet of airflow 220 ′ are on the lower part of the shield, the high temperature is not able to deliver out through airflow 28 ′.

Description
- 1. Field of the Invention
- The present invention relates to a fabric membrane texture and manufacturing method thereof, herein especially comprising a texture and thereof method of reinforced membrane of 3D fabric containing spacer. The method of the present invention applies to outdoor shield or space insulating materials by mainly using the low-pressure fixation process to build up a space of spacer.
- 2. Description of the Related Art
- A fabric normally employing for outdoor shield, space insulating materials or related applications, derivatives and extensions uses is shown in
FIG. 1A which illustrates the distribution of temperature and airflow of monolayer membrane texture from a prior art.FIG. 1A reveals that the inner temperature of this shield increased owing to the outdoor sunshine directly penetrating thismonolayer shield 10′. Thehigh temperature airflow 16′ is in the upper part of this shield, however the inlet ofairflow 12′ and the outlet ofairflow 14′ are on the lower part of the shield which is not able to deliver the high temperature out throughairflow 18′. -
FIG. 1B , schematically diagramed the distribution of temperature and airflow of bi-layer membranes texture from the prior art.FIG. 1B states the inner temperature of the shield is still high although thebi-layer membranes 20′ withinner membrane 22′ have air as an insulator which insulates thehigh temperature airflow 24′ in the area ofinner membrane 22′. Because the temperature difference is not so high betweenhigh temperature airflow 26′ and 24′ and the inlet ofairflow 210′ and the outlet ofairflow 220′ are on the lower part of the shield, the high temperature is not able to deliver out throughairflow 28′. BothFIG. 2A and 2B schematically diagram the texture of tri-layer composite membranes and multilayer composite membranes from a prior art. Referring toFIGS. 2A and 2B , there are tri-layercomposite membrane 30′ comprising alower fabric 32′, aplain woven fabric 34′ and an upper fabric 36′, and multilayercomposite membranes 40′ comprising afabric substrate 42′, asurfactant 44′ and a texture ofporosity PTFE membrane 46′. However, the consequence presented that the thickness is increased and the defect of heat directly penetrating into inner of texture is not improved. - U.S. Pat. No. 6,319,864 discloses that two different textures of fabric adhere to a layer of air impermeable and waterproof polymer membrane to reach the effect of waterproof, thermal preserving and thermal insulation for tri-layer texture fabric. U.S. Pat. No. 5,849,395 discloses the polymer membrane which is affixed to a release thin plate. After a treatment to the said polymer membrane, the thin plate is removed, and the polymer membrane becomes into a two-dimensional reticular to obtain the effect of penetration through the special process. U.S. Pat. No. 4,954,388 discloses the multilayer composite membrane with the properties of abrasion resistance and tear resistance. A porous PTFE membrane is used as a material to strengthen the said multilayer composite membrane property. The polymer is adhered between PTFE membrane and fabric composite to be employed to electromagnetics interruption materials; U.S. Pat. No. 5,692,935 discloses that the composite fabric is made of fabric and a heat sealable film comprising an inner and outer film layer of linear low density polyethylene and an intermediate film layer of a polyamide polymer, which provides a barrier against of solids, liquid and gases.
- The strengthened fabric membrane of two-dimentional fabric, in the examples of U.S. Pat. Nos. 6,319,864 and 5,849,395, only reinforces its strengthened texture design of the plain fabric such as woven fabrics, warp-knitted fabrics, seine fabrics and bonding fabrics etc. The characteristics of the texture are the change of strength and toughness on the direction of plane 360 degrees, but the defect is lack of the effect of impedance and insulation for the efficiency of light, heat and dynamics on the direction of thickness. Especially under the circumstances of the impact of cold-hot environment, the temperature of inner and outer transmitting fast results in the disappearance of the efficiency of insulation due to the time factor and it leads to the disadvantages of high temperature and muggy inside of applications such as curtains and shields under the sunshine in summer.
- Moreover, the known design of bi-layer membranes is base on aforesaid the disadvantages of the strengthened membranes of two-dimentional fabric. One is developed from the fixed gauge of the texture of bi-layer membranes using two styles of fabric membranes through the method of fixed gauge sewing. The fixed gauge requires to be filled in gas and be maintained in order to build up the spacer on the direction of thickness. The purpose is to employ the effect of air layer in the space of the direction of thickness to achieve the high performance of impedance and insulation. The disadvantages of this method are the subsectional design requirement for process, space gauge not able to be precisely controlled, an enormous work, and requiring long time to maintain the supply of inner air pressure.
- Therefore, providing a novel fabric membrane texture and manufacturing method thereof for the aforesaid problems can not only improve the conventional defects of lacking the effect of impedance and insulation of efficiency of light, heat and dynamics in the space of the direction of thickness, but also can be simplified the process. Based on the inventor engaging on the research and develop and sales experiences for the related products for many years, the inventor finally proposes a method to improve the aforementioned problems for fabric membranes texture and its manufacturing process according to his professional background.

The present invention enhances the efficiency of high lightweight for effectiveness of the industry.
- It is another object of the present invention to provide a fabric membrane texture and manufacturing method thereof which of the 3D texture of fixed gauge of spacer is a fiber texture of one-piece form that enables the stability of capability to obtain the best control. At the same time, not only the processing is shortened, but also the requirements for application maintenance are reduced. Especially the prop force of plural connecting fibers in the direction of thickness enables to stably control the space size and efficiency for spacer, to increase the dynamic characteristics in the direction of thickness of fabric membranes and to enhance the capability of dynamic impedance in the plane direction.
- Another purpose of the present invention is to provide the fabric membrane texture and manufacturing method thereof to avoid the crash damage from the high temperature and pressure for the middle connecting fibers, through a process of low-pressure fixation, to exploit the size and characteristics of the fixed spacer.
