Description of the invention: [Technical field of the invention] / ' [0001] The present invention relates to a functional fabric, in particular, a function having both excellent ventilation and protection functions. Sexual fabric. [Prior Art] [0002] Functional fabrics refer to fabrics that have specific functions such as waterproof, breathable, UV-resistant, and impact-resistant, abrasion resistant, lightweight, etc., which are widely used in life leisure or professional fields. Among them, when considering the use of various intense sports, mountaineering activities or military and police firefighters to perform tasks, it is usually necessary to wear or wear clothing or protective gear made of impact-resistant functional fabrics. For the products developed by the relevant manufacturers, the fabric is mainly designed by selecting a material with a shock absorbing effect or a buffer structure, thereby providing a function of reducing the external impact force. [0003] A method of manufacturing a polyurethane pad for protecting a human body, including a tube woven from a loop, one of the tubes, is disclosed in US Pat. No. 4,292,263. A foaming crucible is attached to the outer surface, wherein the foaming mat is made of polyurethane (PU) foam. No. 6,192, 51,9, discloses a sports pad comprising a tube body and a high friction material disposed on the tube body, the tube body including a pad portion and a The non-pad portion is provided with a pad in the pad portion, wherein the pad can be a foamable polymer material, thereby providing a protective effect. [0004] A joint protection device for intense exercise, comprising a cushioning pad, a semi-rigid cover, and a flexure cover, respectively, is disclosed, for example, in US Pat. No. 6,221,768.

Next, please refer to r FIG. 3 ′′, which is a schematic diagram of the functional fabric which has both high ventilation and protection. In the embodiment, the elastic cloth is in a stretched state, and the elasticity is when the user moves. The cloth 10 will be subjected to a force parallel to the joint surface 11, such as bending at the joint or stretching of the body, and the elastic cloth 10 will extend in the lateral direction, at which time the elastic cloth 10 is in a stretched state. Since the elastic cloth 1〇 is tightly coupled to the air permeable cloth 2, the elastic cloth 10 will collectively cause the air permeable cloth 20 to laterally expand, and at the same time, the contact area 21 is in the unstretched state to the The stretched state produces a relative displacement, which in turn is associated with moving the raised region 22 in the direction of the joining face 11, i.e., the chamber 3〇 will be recessed downwardly thereby creating a volume change. As shown in Fig. 3, the volume change will correspondingly cause a pressure difference in the chamber 3, which is the increased pressure in the chamber 30, which will force the gas to flow downward, making the elasticity The portion of the cloth 10 corresponding to the raised region 22 forms a passage for the gas to be guided to the skin, and the gas passes through the passage through the elastic cloth 1 and the flexible layer 50 to reach the human skin, as shown in the figure. The arrow pointing down shows. In addition, since the gas is quickly introduced into the area between the flexible layer 5 and the human skin, gas pressure will also be generated in the area, which will force the human skin to diverge, 099118489 Form No. A0101 Page 9 of 20 Page 1003295384-0 1354720 The year of August 100 is replaced by w to make it restrict to the part between the channels to flow, and then the contact area * 21 domain 21 is discharged to the outside, so the corresponding animal _ cloth 1 〇 corresponds The portion to the contact area 21 will form a passage for the hot gas to exit the skin, as indicated by the upward arrow of the figure. Therefore, the gas and the hot gas will form a gas circulation in the passage, and the functional cloth can be exchanged between the hot and cold gases at the skin when the human body is active. [0022] Please refer to FIG. 4 again, FIG. 4 is a cross-sectional view of the elastic cloth according to another embodiment of the present invention, which is a high-breathable and protective functional cloth, wherein the knitting method according to the elastic cloth is changed. The raised region 22 can be designed such that the outer diameter of the top portion 222a is larger than the peripheral edge portion 221a, so that the raised portion 22 has a drop-like appearance. In addition, in order to reduce the barrier of entry of the gas into the skin, the bonding layer 40 may also selectively place the bonding region 41 on the 5H bonding surface 11, as shown in the figure, the bonding layer 40 will contain a The blank regions 43 corresponding to each other in the raised regions 22 can be achieved by using a screen or other similar device when applying the moisture-curing polymer glue.

The splicing section 141 is combined with the top layer 12 and the bottom layer 13 by means of a thimble, and the splicing layer 4G is made of a polyurethane (four) moisture-curing polymer kick, wherein the above-mentioned Daniel refers to every 9 The fiber weight of glutinous rice (g). [0025] Regarding the air permeability and the impact resistance, the US material test is respectively used.

ASTM D737, a textile breath test method developed by the American Society for Testing and Materials (ASTM), and a drop impact tester. For the comparative example used, neoprene was used. For detailed data, please refer to Table 1 'where ASTM D737 measures the air per cubic foot per minute (cfm); the impact energy used in the impact test is 6 joules. When the impact cloth 20 is hit by the impact energy, the load on the other side of the impact surface (unit is kilonewtons, kN for short) is measured. Table 1

EXAMPLES Comparative Example

As can be seen from the above table, the functional fabric disclosed in the examples can pass 34.90 cubic feet of air per minute in the astm D737 test, and 0 cubic feet in the comparative example. As for the impact test part, if the user wears the functional fabric of the embodiment under the impact energy of 6 joules, it will only receive a load of 10.3 kN; if it is a comparative example of the rubber knee, then 099118489 will be subjected to 17. 4 Form number A0101 kN load. Therefore, the above examples are superior to neoprene in both the air permeability and the impact resistance on the 11th/20th page 1003295384-0 1354720 100 years on August 15th. [0028] In summary, the present invention combines the design of the high-breathability and the raw fabric with the design of the raised area, and the chamber is formed in the functional fabric, and the chamber can be repeated with the movement of the human body. The contraction and expansion of the ground, the pressure difference generated by the volume change, the gas can be introduced into the human skin, and at the same time, the hot air generated by the human skin is quickly discharged, and even if the supporting layer is provided in the elastic cloth, The pressure difference can also force the gas to penetrate the elastic cloth, thus producing the effect of circulating hot and cold gases. At the same time, the three-dimensional structure design of the ridge area and the support section can also reduce the damage of the external impact on the human body, thereby achieving the purpose of high gas permeability and high protection ability.

[0029] In addition, in the elastic cloth, the bottom layer and the top layer can be woven in the weft direction and the warp direction respectively, and the supporting section can be matched, so that the functional fabric can have excellent stretching ability in three dimensions. In order to allow the user to move without restraint, and because the breathable cloth can be manufactured by a warp knitting machine, it can have wear resistance characteristics. Therefore, the present invention is highly progressive and conforms to the requirements for applying for a patent for invention, and is filed according to law, and the Prayer Council grants a patent at an early date.
