Problems solved by technology

[0004] However, in the case of superhydrophobic treatment, due to the use of silicone or fluoropolymer-based agents, the textile material will become stiff after high temperature curing
More importantly, due to the cross-linking effect of the polymer, a polymer film is formed on the surface of the material, and the part that directly contacts the skin becomes sultry and hot, hindering the export of a large amount of sweat, and the sweat remains in the inner layer, which seriously affects the wearing of clothing materials comfort

Embodiment approach

[0037] According to a preferred embodiment of the present invention, the preparation method of the superhydrophobic functional material comprises the following process steps:

[0038] (1) Fabric pretreatment to remove wax, oil and surfactants that may remain on the material.

[0039] (2) Prepare superhydrophobic lattices or ribbons by dot printing method or continuous imprinting method.

[0040] (3) Circulating hot air drying.

[0041] Preferably, the fabric pretreatment process uses Na 2 CO 3 : 5%, temperature 40-45°C, time 15-20min, liquid retention rate 50%; then dry at 100°C for 2min.

[0042] Preferably, the material is coated at room temperature.

[0043] Preferably, the temperature of the circulating hot air drying is 70-100° C., and the time is 1-2.5 minutes.

[0044] According to a preferred embodiment of the present invention, the super-hydrophobic functional material is a chemical method, using a super-hydrophobic agent to draw a specific pattern with a hydroph...

Embodiment 1

[0064] Pre-treat high-count pure cotton fabrics to remove waxes, oils and surfactants that may remain on the material.

[0065] Using nano-silica as an additive, prepare a super-hydrophobic working solution with a concentration of 70g / l and a pH value of 6-6.5, put it into a liquid storage tank, and print on a dot printing device.

[0066] Put it into an oven and dry at 100°C for 2 minutes to obtain a super-hydrophobic functional pure cotton fabric.

Embodiment 2

[0068] The natural ramie fabric is pretreated to remove waxes, oils and surfactants that may remain in the material.

[0069] Using nano-zinc oxide as an additive, prepare a super-hydrophobic working solution with a concentration of 70g / l and a pH value of 6-6.5, put it into a liquid storage tank, and print on a continuous imprinting device.

[0070] Put it into an oven and dry at 100°C for 2 minutes to obtain a superhydrophobic functional ramie fabric.

Abstract

The invention relates to a super-hydrophobic functional material and a preparation method thereof. The super-hydrophobic functional material comprises a base with a hydrophilic nature and a pattern which is located on at least one portion of the base and comprises at least one hydrophilic portion and at least one super-hydrophobic functional portion, wherein the super-hydrophobic functional portion comprises a compound of nano silicon dioxide, nano zinc oxide or nano titanium dioxide. The super-hydrophobic functional material provided by the invention has a good hydrophobic property and can resist wetting and contamination of external aqueous matters. As a result of the hydrophobic characteristic of the base material, the whole clothes product still maintains the most original characteristics. The hydrophobic textile material provided by the invention has the functional characteristics of absorbing moisture and keeping shape, ventilating and being comfortable and being hard to wrinkle, and is particularly suitable for informal clothes of businessmen and personal clothes in humid and muggy environments.

Description

technical field [0001] The invention belongs to the field of textile materials, in particular to a unidirectional conduction superhydrophobic functional material and a preparation method thereof. Background technique [0002] In the hot season and hot and humid environment, in order to prevent the body temperature from rising too fast, the human skin will emit a lot of sweat, and the sweat evaporates to take away the heat to maintain normal body temperature. According to literature reports, when the temperature is 29 degrees, the total amount of human sweat is about 1.9-3.8kg. The shirts and underwear that people wear every day often become sticky and unbearable due to sweat, which is not conducive to the breathing of the skin. The accumulation of inorganic components such as sodium chloride and calcium carbonate in sweat will damage the tissue cells on the surface of the skin; the organic components in sweat will be more conducive to the proliferation of microorganisms on ...
