1 is a schematic view of a preferred embodiment of the present invention; FIG. 2 is a flow chart of a preferred embodiment of the present invention; and FIG. 3 is an AATCC standard spray test evaluation drawing.

As shown in the preferred embodiment of FIG. 1, the fabric structure 800 of the present invention comprises a fabric layer 100, a barrier bridging layer 300, and a surface layer 500. The fabric layer 100 is hydrophilic. The barrier bridging layer 300 is hydrophobic and disposed on the fabric layer 100. The surface layer 500, which is hydrophobic, is disposed on the barrier bridging layer 300. The bonding force between the surface layer 500 and the barrier bridging layer 300 is greater than the bonding force between the surface layer 500 and the fabric layer 100. Wherein, the barrier bridging layer 300 and the surface layer 500 are hydrophobic, which means that the contact angle of water on both surfaces exceeds 90°.

In a preferred embodiment, fabric layer 100 comprises a plurality of hydrophilic fibers. Among them, the hydrophilic fiber comprises a natural fiber, a hydrophobic fiber treated with a hydrophilic agent, or a combination thereof. The natural fiber is contained as a plant fiber such as cotton or hemp or an animal fiber such as wool or silk. . In various embodiments, fabric layer 100 comprises a plurality of hydrophobic fibers and a hydrophilic agent. Specifically, the hydrophilic agent may be distributed in the gaps of the hydrophobic fibers and the peripheral surface, whereby the fabric layer 100 as a whole is hydrophilic. Wherein, the hydrophilic agent comprises a cation type silicon, an aminosilicon, a non-anionic polyoxyethylene type compound, a non-anionic polyethylene glycol compound or a mixture thereof. The hydrophobic fibers may comprise polyester fibers, nylon fibers, polyester/iron-resistant interwoven fibers or acrylic fibers.

The material of the barrier bridging layer 300 is selected from Acrylic, Polyurethane (PU), Epoxy or a composition thereof. The material of the surface layer 500 is selected from the group consisting of fluorocarbon compounds. In a preferred embodiment, since the fabric layer 100 has substantially voids, the barrier bridging layer 300 may partially penetrate the fabric layer 100, that is, the barrier bridging layer 300 may partially penetrate the surface of the fabric layer 100 in contact with the fabric layer. 100 is in the vicinity of the pores of the contact surface. On the other hand, for the barrier bridging layer 300 having substantially voids, the surface layer 500 may partially penetrate the barrier bridging layer 300, that is, the surface layer 500 may partially penetrate the surface of the barrier bridging layer 300 in contact with the barrier bridging layer 300. Close to the pores of this contact surface.

Specifically, when moisture contacts a portion of the fabric layer 100, the fabric layer 100 of the present invention has good drainage properties because it is hydrophilic and rapidly spreads around. Further, since the surface layer 500 is hydrophobic and the aqueous soil is less likely to penetrate into the surface layer 500, the fabric structure 800 of the present invention has good stain resistance. On the other hand, in order to improve the above drainage and stain resistance, the fabric layer 100 preferably has high hydrophilicity, and the surface layer 500 preferably has a high Hydrophobic. However, a highly hydrophilic substance and a highly hydrophobic substance are usually not easily bonded due to a low bonding force. In other words, the highly hydrophobic surface layer 500 is generally not readily disposed directly on the highly hydrophilic fabric layer 100. Therefore, the present invention additionally provides a barrier bridging layer 300 between the fabric layer 100 and the surface layer 500. The bonding force between the barrier bridging layer 300 and the fabric layer 100 is greater than the bonding force between the surface layer 500 and the fabric layer 100, and the bonding force between the barrier bridging layer 300 and the surface layer 500 is greater than the surface layer 500 and the fabric layer 100. The bond strength between the two. As such, the surface layer 500 can be attached to the fabric layer 100 more indirectly by the bridging layer 300.

As shown in the embodiment of Fig. 2, the fabric structure manufacturing method of the present invention comprises, for example, the following steps.

In step (A1), a fabric layer is provided, the fabric layer being hydrophilic. Specifically, a fabric layer woven from a plurality of hydrophilic fibers is provided, or a fabric layer woven from a plurality of hydrophobic fibers and having a hydrophilic agent distributed on the surface or the gap of the fibers is provided.

Step (A2), providing a surface layer material and a barrier bridging layer material, wherein the surface layer material and the barrier bridging layer material are both hydrophobic, and the bonding force between the barrier bridging layer material and the fabric layer material is greater than the surface layer material and the fabric layer material The bonding force between the surface layer material and the barrier bridging layer material is greater than the bonding force between the surface layer material and the fabric layer material.

In step (A3), a barrier bridging layer is provided on the hydrophilic fabric layer using a barrier bridging layer material. Further, the step (A3) comprises: (A3-1) preparing a viscous solution of the barrier bridging layer material containing the barrier bridging layer material; (A3-2) applying the viscous solution of the barrier bridging layer material to the hydrophilic fabric layer, Specifically, it is applied to one side of the hydrophilic fabric layer; and (A3-3) the viscous solution of the barrier bridging layer material coated on the hydrophilic fabric layer is dried to form a barrier bridging layer. Among them, the step (A3-2) involves the use of a foam coating method. (A3-1) contains multiple barriers The bridging layer material is prepared as a viscous solution for the barrier bridging layer material, wherein the plurality of barrier bridging layer materials may comprise a first barrier bridging layer material and a second barrier bridging layer material, and the ratio of the first and second barrier bridging layer materials is 3:7- 7:3, and the barrier bridging layer is preferably comprised of a thickener, a foaming agent or a combination thereof. The foam ratio is between 5 and 10 times. The drying method used in (A3-3) may be baking drying or infrared drying.

In step (A4), the surface layer material is used to set the surface layer on the barrier bridging layer. Further, the step (A4) comprises: (A4-1) preparing a viscous solution of the surface layer material containing the surface layer material; (A4-2) coating the surface layer material viscous solution on the barrier bridging layer; and (A4- 3) Drying the surface layer material solution applied on the barrier bridging layer to form a surface layer. The surface layer material viscous solution of the step (A4-1) contains a thickener, wherein the thickener may be polyacrylic acid. Step (A4-2) involves the use of a foam coating method. The foam ratio is between 5 and 10 times. The drying method used in the step (A4-3) may be baking drying or infrared drying. In particular, since the barrier bridging layer 300 is hydrophobic, when the surface layer 500 is disposed on the barrier bridging layer 300 using the surface layer material (as shown in FIG. 1), the viscous solution of the surface layer material can be prevented from passing through the barrier bridging layer. 300 is infiltrated into the fabric layer 100.
