It is well mixed among state polytetrafluoroethylene (PTFE)；
2) by step 1）In liquid polytetrafluoroethylene be coated with hydrophilic membrane, to form Teflon membranes；
3) hexadecyl trimethoxy silane film layer is placed in methanol and soaked；
4) filling of acryloyl chloride is carried out using graft process on the surface of Teflon membranes, and by step 3）It is middle to complete leaching
The hexadecyl trimethoxy silane film layer of bubble is placed on the Teflon membranes filled with acryloyl chloride；
5) carried out by heat pressing process hydrophilic membrane, Teflon membranes and hexadecyl trimethoxy silane film layer
Connection processing is molded, to form Waterproof Breathable composite membrane, and is cooled down for the Waterproof Breathable composite membrane after shaping.
Using the Waterproof Breathable composite membrane based on composite film structure of above-mentioned technical proposal, its can by hydrophilic membrane with
The fitting of hydrophobic film layer with realize Waterproof Breathable handle；Among above-mentioned hydrophobic film layer, it can be formed by Teflon membranes
Good waterproof effect, and the setting of hexadecyl trimethoxy silane film layer on the one hand can be in auxiliary Teflon membranes shape
While into auxiliary hydrophobic effect so that fabric is inherently more comfortable, and causes the Waterproof Breathable composite membrane in the application and face
The fitting effect of material is improved, so the overall performance of the Waterproof Breathable composite membrane in the application is promoted be improved it is same
When, the another using effect for using the fabric of Waterproof Breathable composite membrane in the application can also be improved.
