preparation example Construction

[0029] Such as figure 1 Shown, the present invention provides a kind of preparation method of low surface energy foaming polyester fabric, comprises the steps: Step 1: the polyester fabric after cleaning and drying is in supercritical CO 2 Foaming is carried out in the extraction device; step 2: evaporating low surface energy material PTFE on the surface of the foamed polyester fabric.

[0030] The above-mentioned preparation method adopts such as figure 2 The preparation setup shown includes CO 2 Gas storage tank 1, foaming kettle 2 and low surface energy material PTFE evaporation chamber 3, said foaming kettle 2 is supercritical CO 2 extraction unit, the CO 2 The gas outlet of the gas storage tank 1 is connected to the air inlet at the bottom of the foaming kettle 2 through a pipeline. When foaming, the polyester fabric is placed in the inner middle of the foaming kettle 2, and the foaming kettle 2 is filled with supercritical CO2 from bottom to top. 2 gas. During eva...

Embodiment 1

[0038] A method for preparing a low surface energy foamed polyester fabric, the specific steps are: cutting the polyester white gray cloth into 40cm×15cm, soaking the polyester white gray cloth in hot soapy water at 60°C for 15 minutes; rinsing the excess foam with clean water after washing foam, then placed in an ultrasonic cleaning machine filled with absolute ethanol for 15 minutes of ultrasonic cleaning; after ultrasonic washing, rinse excess ethanol with water, and finally rinse with deionized water, and dry in an oven at 80°C. Put the dried polyester white gray cloth into supercritical CO 2 In the extraction device, the temperature is set to 150°C, the pressure in the foaming tank rises to 10MPa, and the pressure is maintained for 10h, and the supercritical CO 2 It can be fully dissolved in the polyester fabric, and the pressure can be released quickly to make a porous foamed polyester fabric.

Abstract

The invention provides a preparation method of a low surface energy foamed polyester fabric. The preparation method comprises the following steps: step one, putting a cleaned and dried polyester fabric into a supercritical CO2 extraction device for foaming; step two, evaporating a low surface energy substance PTFE on the surface of the foamed polyester fabric. The preparation method disclosed by the invention has the advantages of simple process, convenience in operation, low cost and no pollution; the prepared low surface energy foamed polyester fabric has the functions of light weight, thermal insulation, water repellency, oil repellency and the like.

Description

technical field [0001] The invention relates to the technical field of preparation and development of multifunctional textiles, in particular to a preparation method of low surface energy foamed polyester fabric. Background technique [0002] Due to its low density, unique volume and surface effect, and excellent mechanical, acoustic, and thermal insulation properties, porous materials provide great possibilities for structural lightweight, thermal insulation, energy absorption, and adsorption. Become the focus of the research field of multifunctional textiles. The combination of various excellent properties of porous materials makes it widely used, and plays an important role in chemical industry, metallurgy, aerospace and other fields. [0003] As one of the important means of forming cells, foaming is mostly used to produce porous foam materials such as films and plastics, but there are few porous foam fabric materials. At present, the development of textile materials, ...
