Spray method of testing (AATCC193Test)
Spray method of testing can assist judgment object for the repellence of waterborne liquid, and its waterborne liquid repellence score criteria is as shown in table 1:
Table 1 sprays the score criteria of method of testing
| Waterborne liquid repellence score criteria | Test liquid forms |
| 0 | Failure, 98% water |
| 1 | 98: 2/ water: isopropyl alcohol (vol: vol) |
| 2 | 95: 5/ water: isopropyl alcohol (vol: vol) |
| 3 | 90: 10/ water: isopropyl alcohol (vol: vol) |
| 4 | 80: 20/ water: isopropyl alcohol (vol: vol) |
| 5 | 70: 30/ water: isopropyl alcohol (vol: vol) |
| 6 | 60: 40/ water: isopropyl alcohol (vol: vol) |
| 7 | 50: 50/ water: isopropyl alcohol (vol: vol) |
| 8 | 40: 60/ water: isopropyl alcohol (vol: vol) |
The dish of a 25mm diameter is cut into sheet material for testing by Capillary Flow porometry.Described same sample is also used to test water permeability under stress.These data present in Table 1.
Example 1:
On the surface of prepared film sample is dripped, different test liquids carries out spray test, after waiting for for 10 seconds, observes and obtains repellence mark.Find after tested, the PVA film through Novec2708 coating can reach the aqueous solution repellence of mark 8; PVA film through Novec1700 coating can reach the aqueous solution repellence of mark 7.Known via described test result, use the water-soluble container obtained by soluble packing membrane of the present invention, because it has excellent in water repellence, therefore can the water content of cleaning agent component in hoisting container, that is component content in addition to water can reduce in expression cleaning agent, the cost of the cleaning agent therefore packed with water-soluble container of the present invention will reduce, and this is benefit of the present invention.
Example 2:
Water droplet on the surface of prepared sample is dripped, measures water droplet in the contact angle (contactangle) of sample surface.Fig. 3 display is through fluoridizing the coating of acryl system resin solution and without the test result of PVA film of fluoridizing the resin solution coating of acryl system.Fig. 3 (a) shows, and water droplet is dispersed in soon without fluoridizing on the PVA film of acryl system resin solution coating, and damages described PVA film.Fig. 3 (b) shows, and the contact angle of water droplet on PVA film apply through Novec1700 is about 88 degree, but the angle increasing contact angle along with the time reduces, and this is start to infiltrate PVA film because of water droplet.Fig. 3 (c) shows, and the contact angle of water droplet on the PVA film applied through Novec2708 is about 102 degree.
Example 3:
Known through above-mentioned example, PVA film through fluoridizing the resin solution coating of acryl system has a water resisting property, but consider for being used for making detergent pouch by the described PVA film through fluoridizing the coating of acryl system resin solution, therefore its solubility system in water is quite important.After tested, after approximately passing through 155 seconds without the PVA film fluoridizing the resin solution coating of acryl system, can be dissolved in the water completely; After the PVA film of Novec1700 coating approximately passes through 168 seconds, can be dissolved in the water completely; After the PVA film of Novec2708 coating approximately passes through 253 seconds, can be dissolved in the water completely.Significantly, during through costing containing the PVA film fluoridizing the resin solution process of acryl system of higher concentration, the more time could be dissolved in the water completely, but described longer number of seconds is still can accept in time range.
Example 4:
Get one block of glass, respectively by without fluoridize acryl system resin-coating PVA film, through Novec1700 coating PVA film and through Novec2708 coating PVA Film Fractionation in water, and with glass surface described in these aqueous solution wipings, then water droplet is dripped on described glass surface, observe water droplet form.Fig. 4 (a) shows, and water droplet form is on the glass surface defeated and dispersed, and this illustrates without fluoridizing the PVA Film Fractionation of acryl system resin in water, after using described solution cleaning glass window surface, can't form hydrophobic diaphragm at glass surface.
By the PVA Film Fractionation that applies through Novec1700 in water, use described solution cleaning glass window surface, then drip water droplet on the glass surface and observe water droplet form, result is as shown in Fig. 4 (b).Compared to the globule form of Fig. 4 (a), the globule form of Fig. 4 (b) is more complete.
By the PVA Film Fractionation that applies through Novec2708 in water, use described solution cleaning glass window surface, then drip water droplet on the glass surface and observe water droplet form, result is as shown in Fig. 4 (c).Compared to the water droplet form of Fig. 4 (a) and Fig. 4 (b), the water droplet form of Fig. 4 (c) is more complete.
According to the above results; to have after the PVA Film Fractionation comprising the hydrophobic film fluoridizing acryl system resin forms solution in water; use described solution wiping (or clean) body surface; can form a hydrophobic protective layer on described body surface, this is benefit of the present invention.
Announcement of the present invention is intended to explain how to be formed and to use various according to embodiments of the invention, and unrestricted of the present invention real, be intended to and appropriate category and spirit of the present invention.More than discuss and be not intended for detailed or the present invention be limited to disclosed clear and definite form.In view of above teaching, it is possible for revising or changing.Can select and describe embodiment to provide the best illustration to principle of the present invention and practical application, and making to have the knack of the technology person and can utilize the present invention in various embodiments and there are the various changes being suitable for the specific use expected.When according to through just, legal and the range of rational delegation of power is explained time, all these revise and change in the category defined by appended claim and its equivalents all of the present invention, can be revised these in the unsettled period of this application case of patent and revise and change.
