Problems solved by technology

[0002] Buildings in various countries, especially residences, hotels, etc., are equipped with screens to prevent insects from entering for ventilation. However, because the screens (usually called insect-proof nets abroad) have no hydrophobic function, rainwater often enters the room from the screens when it rains, causing inconvenience.

Embodiment 1

[0009] Using 0.5mm stainless steel single fiber as raw material, the fiber raw material is woven into 24-mesh window screen by textile machine. After cleaning the window screen with detergent and water, the hydrophobic treatment is carried out by dipping method, and the window screen is soaked in polytetrafluoroethylene hydrophobic agent AG- In 700, treat at room temperature for 1.5 hours, the thickness of the hydrophobic agent coating reaches 50 μm, heat treatment after dipping, the temperature is 250 ° C, and the time is 15 minutes. After drying, it is rolled into a finished product.

Embodiment 2

[0011] 80 glass fibers are used as raw materials, and the fiber raw materials are woven into 40-mesh window screens with arrow shaft machines. After cleaning the window screens with detergent and water, hydrophobic treatment is carried out by coating method. Silicone hydrophobic agent TS-2001 Coated on the surface of the window screen fiber, the thickness of the hydrophobic agent coating reaches 30 μm, and heat treatment is carried out after coating, the treatment temperature is 180 ° C, and the time is 30 minutes. After drying, it is rolled into a finished product.

Embodiment 3

[0013] Using 10μm stainless steel fiber as raw material, the fiber raw material is woven into a 1000-mesh filter screen with an air-jet loom. After the filter screen is cleaned with detergent and water, the hydrophobic treatment is carried out by dipping method, and the filter screen is soaked in polytetrafluoroethylene hydrophobic agent. In AG-70, treat at room temperature for 10 minutes, and the thickness of the hydrophobic agent coating reaches 0.5 μm. After dipping, heat treatment is carried out at a temperature of 350 ° C for 5 seconds. After drying, it is rolled into a finished product.

Abstract

The invention discloses a hydrophobic curtain and screen preparing method, which is characterized by the following: utilizing textile machinery to weave fiber material into 18-1000 order curtain or screen; washing curtain or screen through detergent and clean water; adopting immersing method or coating method to proceed hydrophobic disposal; soaking curtain or screen in the hydrophobic agent for 5 s to 5 h through soaking method; coating the hydrophobic agent on the curtain or screen fiber surface through coating method; drying curtain or screen at 80-350 deg.c for 5s to 60 min; coiling the product; fitting hotel, house, writing building and each professional solid-liquid separating technology.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of a hydrophobic window screen and a filter net. Background technique [0002] Buildings in various countries, especially residences, hotels, etc., are equipped with screens to prevent insects from entering for ventilation. However, because the screens (usually called insect-proof nets abroad) have no hydrophobic function, rainwater often enters the room through the screens when it rains, causing inconvenience. . In addition, filter screens are commonly used for gas-solid separation or liquid-solid separation. If the filter screen has hydrophobic properties, it will help reduce the attachment of solid particles on the screen, reduce filtration resistance, and improve the stripping of solid particles. Contents of the invention [0003] Aiming at the shortcomings of currently used window screens and filter screens, the invention provides a metho...
