Embodiment 1

[0030] A hydrophobic fabric with a surface imitating the structure of Nepenthes, including yarn (1) and hydrophobic layer (2), 8 μm glass fiber yarn as raw material, a weave structure with a weave factor of 1, and a warp and weft density of 32*58 interwoven Form the main fabric.

[0031] The main fabric is post-treated with super-hydrophobic paint to form a hydrophobic layer. The surface of the hydrophobic layer contains randomly distributed 7-10μm large sheet-like dot structures. The hydrophobic layer does not completely cover the entire main fabric, and the top of the main fabric is not covered by hydrophobic materials. covered, the apex not covered by the hydrophobic material forms a crescent structure (3).

[0032] The density of the crescent structure (3) is controlled by the warp and weft density of the main fabric, the size of the crescent structure (3) is controlled by the diameter of the yarn and the structure, and the maximum width of the formed crescent structure (3...

Embodiment 2

[0034] A hydrophobic fabric whose surface imitates the structure of Nepenthes, including yarn (1) and hydrophobic layer (2), 16 μm glass fiber or strong fiber yarn as raw material, a weave structure with a weave coefficient of 3, and a warp and weft density of 46 *75 interweaves to form the main fabric.

[0035] The main fabric is post-treated with super-hydrophobic paint to form a hydrophobic layer. The surface of the hydrophobic layer contains randomly distributed 8-10μm large sheet-like dot structures. The hydrophobic layer does not completely cover the entire main fabric. The top of the main fabric is not covered by hydrophobic materials. covered, the apex not covered by the hydrophobic material forms a crescent structure (3).

[0036] The density of the crescent structure (3) is controlled by the warp and weft density of the main fabric, the size of the crescent structure (3) is controlled by the diameter and structure of the yarn, and the maximum width of the formed cres...

Embodiment 3

[0038] A hydrophobic fabric with a surface imitation pitcher plant structure, including yarn (1) and hydrophobic layer (2), 12 μm glass fiber or rich fiber yarn as raw material, a weave structure with a weave factor of 1.7, and a warp and weft density of 36 *62 interwoven to form the main fabric.

[0039] The main fabric is post-treated with super-hydrophobic paint to form a hydrophobic layer. The surface of the hydrophobic layer contains randomly distributed 5-7μm large sheet-like dot structures. The hydrophobic layer does not completely cover the entire main fabric, and the top of the main fabric is not covered by hydrophobic materials. covered, the apex not covered by the hydrophobic material forms a crescent structure (3).

[0040] The density of the crescent structure (3) is controlled by the warp and weft density of the main fabric, the size of the crescent structure (3) is controlled by the diameter of the yarn and the structure, and the maximum width of the formed cres...

Abstract

The invention provides a hydrophobic fabric with a surface imitating the structure of Nepenthes, comprising yarns (1) and a hydrophobic layer (2), interweaving the yarns to form a main fabric, and then post-processing the hydrophobic material to obtain a hydrophobic fabric, the surface of the hydrophobic fabric Containing crescent structure and hydrophobic material, the surface contains dot structure after drying, wherein the hydrophobic material does not completely cover the whole of the main fabric, and the top of the main fabric is not covered by the hydrophobic material, so the top that is not covered by the hydrophobic material forms a crescent structure (3 ), the density of the crescent structure (3) is controlled by the warp and weft density of the main fabric, and the size is controlled by the diameter and structure of the yarn. The hydrophobic fabric with the structure imitating the pitcher plant on the surface prepared by the invention has a large contact angle, reaches the super-hydrophobic level, and can be used for outdoor clothing, cleaning products and the like.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of textile materials, and in particular relates to a hydrophobic fabric whose surface imitates the structure of nepenthes. [0003] Background technique: [0004] Nepenthes is a kind of insectivore whose leaves are like water cups. Especially after the rain, the surface of the leaves of Nepenthes becomes almost frictionless and emits a sweet smell, which attracts insects such as ants, spiders, and small frogs. Nepenthes The top of the top is a super slippery layer, which can not only slide to insects, but also exclude a variety of liquids and solids. With almost no thrust and no tilt, it can allow liquids or solids to slide down from its surface without hindrance. The leaf effect is used more widely. [0005] The reason why Nepenthes has excellent hydrophobic performance comes from the crescent shape and irregularly arranged waxy crystals on its surface. Studies have shown that the edge of the cresc...
