Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): a waterproof fabric is shown in figure 1 and comprises a base fabric 1, wherein the base fabric 1 is formed by interweaving Shengma fiber and polyester fiber, and is soft in material and light in weight, so that people can wear the fabric more conveniently.

As shown in fig. 1, a thickening layer 2 is arranged on one side of a base fabric 1, and the thickening layer 2 is sewn with the base fabric 1 by thread rolling. Thickening layer 2 adopts is cotton-flax cloth, and thickening layer 2's setting has increased the utility model discloses a thickness, the user is wearing like this the utility model discloses during the clothing of making, user's skin is difficult more and water contact to waterproof nature has been improved.

As shown in fig. 1, the surface of the thickening layer 2 is provided with a first vent hole 21 extending through the thickness direction thereof. The setting of first bleeder vent 21 makes the utility model discloses when utensil waterproof function, can have better gas permeability to improve the travelling comfort.

As shown in fig. 1, a waterproof layer 3 covers the surface of one side of the thickening layer 2, which is far away from the base fabric 1, and the thickening layer 2 and the waterproof layer 3 are glued together. The waterproof layer 3 is a PTFE clothing film, and the material is made into a microporous film by utilizing the pore-forming characteristic of polytetrafluoroethylene plastic resin and adopting a biaxial stretching method. The diameter of the micropores in the microporous structure is hundreds of times smaller than that of water molecules, but tens of thousands of times larger than that of water vapor molecules, so that water vapor can pass through the micropores, and water drops can hardly pass through the micropores, and thus the waterproof layer 3 has a good waterproof function.

As shown in fig. 1, the surface of the waterproofing layer 3 facing away from the thickening 2 is coated with a water-barrier coating 4. The waterproof coating 4 is SBS waterborne polyurethane waterproof paint which is liquefied under high pressure and then sprayed on the surface of the waterproof layer 3 in a gas form. When water is sprayed on the water-blocking coating 4, the water-blocking coating 4 automatically disperses.

As shown in fig. 1, the surface of the water barrier coating 4 facing away from the waterproof layer 3 is coated with a layer of fixing glue 5. Fixed glue film 5 is for using PU to glue the coating solvent of raw and other materials, and it has better prevention of seepage and passes through the effect, has consequently further strengthened the utility model discloses a waterproof ability.

As shown in fig. 1, the surface of the fixing adhesive layer 5 facing away from the water-proof coating 4 is provided with a diversion trench 51. When water sprinkled on the surface of the fixed glue layer 5, water flow can flow out along the diversion trench 51 the utility model discloses, consequently reduced the utility model discloses the adhesion of water on the surface, the event has further improved waterproof performance.

As shown in fig. 1, one side of the base fabric 1 departing from the waterproof layer 3 is sewed with a quick-drying layer 6 by thread rolling, the quick-drying layer 6 is cloth made of polyester fiber, and the cloth is dry for a long time due to low moisture content, so that people can wear the utility model discloses when the clothing is made, the skin feels drier.

As shown in figure 1, the quick-drying layer 6 is provided with a second air hole 61 along the thickness direction, and the second air hole 61 is arranged, so that people feel dry and comfortable, and can better ventilate, and people feel more comfortable when wearing the quick-drying layer.

As shown in fig. 1, a flexible layer 7 is sewn on one side of the quick drying layer 6, which is far away from the base fabric 1, by thread rolling, and the flexible layer 7 is made of bamboo fiber fabric which is prepared by taking natural moso bamboo as a raw material and cooking, hydrolyzing and refining the raw material. Because bamboo fibre surface fabric has better close skin nature, and its is comfortable ventilative, so the setting of flexible layer 7 has further improved the utility model discloses a travelling comfort.

The specific implementation process comprises the following steps: and (3) sewing a thickening layer 2 on one side of the base fabric 1 by thread rolling, and gluing and fixing a waterproof layer 3 on one side of the thickening layer 2 far away from the base fabric 1. And a waterproof coating 4 is coated on the surface of the waterproof layer 3, which is far away from the thickening layer 2, and a fixing adhesive layer 5 is coated on one side, which is far away from the waterproof layer 3, of the waterproof coating 4. And sewing the quick-drying layer 6 on one side of the base fabric 1, which is far away from the thickening layer 2, by linear rolling, and sewing the flexible layer 7 on one side of the quick-drying layer 6, which is far away from the base fabric 1, by linear rolling.

Because the setting of waterproof layer 3, and waterproof layer 3 adopts the PTFE clothing membrane, the cellular structure on it is difficult to let the hydrone pass, and the vapor molecule can pass the micropore easily, so when the water spray the utility model discloses a when on the surface, water can not pierce through, so have better waterproof function.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
