Embodiment 1

[0043] in such as figure 2 On the ground electrode 3 of the schematic reactor, each material area of ​​positioning silicon, PE and PP is at 2-10cm 2 3 sets of smoothing bases in the range. Position a set of similar substrates at position 6. Set the C 2 f 4 The reactor was fed continuously at 6 sccm and the pressure was set at 300 mTorr. An RF generator was connected to the reactor and allowed to discharge at an input power of 50 watts for 90 minutes and then turned off.

[0044] Another glow discharge was then performed with a similar set of substrates in the glow position and no substrate in the post-glow position, except that the modulation was achieved by the pulse generator with a time of 10 milliseconds ON and a time of 190 milliseconds OFF, other conditions and Same as above.

[0045] At the end of both discharges, the substrates were removed from the reactor and their WCA was measured. It can be found from the WCA values ​​listed in Table 1, which are compared w...

Abstract

The present invention relates to textile articles and clothing such as outdoor garments, indoor garments exposed to aqueous liquid, swim wear, leather, hats, textile sun roofs for cars, sun blinds or awnings which have at least part of their surface provided with super hydrophobicity.

Description

field of invention [0001] The present invention relates to textiles and clothing such as outdoor clothing, indoor clothing exposed to aqueous liquids, swimming clothing, shoes, leather, hats, textile grilles for cars, sunblinds or awnings, having super Hydrophobic. Background of the invention [0002] For example, U.S. Patent No. 3,498,527 teaches that paperboard containers for liquids can be made waterproof by applying a water-resistant coating such as wax or polyethylene, and in U.S. Patent No. 2,708,645 about waterproof paper beverage cups and U.S. 3,212,697 about grocery store cardboard bags , which lists similar methods. In US 3,597,313 paper is coated with a polymeric alcohol-polymeric aldehyde reaction product to give the paper temporary wet strength. [0003] The coating process has found itself in the manufacture of disposable items in sanitary clothing. In U.S. Patent No. 3,078,849, disposable sanitary napkins are disclosed consisting of an absorbent layer with ...
