## Abstract

The present invention discloses a substrate for a sanitary mask, wherein the substrate is formed by Roll to Roll process and has anti-UV function. The process includes a step of mixing photochromic dye and resin.

## Claims

### Claim 1

A method of manufacturing a mask, comprising:
preparing a roll-to-roll device including at least three rolls;
driving said at least three rolls with a driving device to move a substrate to pass through a tank with a material for attaching onto said substrate, wherein a process for attaching said material includes dipping, inkjet printing, spraying, printing or coating;
moving said substrate from one end to another end in order for said attached substrate to be rolled to and collected at another end; and
performing subsequent processing to said rolled substrate to form said mask.

### Claim 2 (depends on 1)

The method of claim 1, further comprising controlling a rotation rate of said at least three rolls to control a moving rate of said substrate, so as to control a thickness or amount of said material.

### Claim 3 (depends on 1)

The method of claim 1, further comprising correspondingly disposing a heating device at a side of said substrate to provide a heating source for drying said material.

### Claim 4 (depends on 3)

The method of claim 3, wherein said heating device includes lamp, hot blast, electromagnetic radiation or infrared ray heater.

### Claim 5 (depends on 1)

The method of claim 1, wherein said material includes UV absorbent, photochromic dye, resin or any combination thereof to form an outer layer of said mask.

### Claim 6 (depends on 1)

The method of claim 1, wherein said material includes said ultra-micro-perforated filtering membrane to form a middle layer of said mask.

### Claim 7 (depends on 1)

The method of claim 1, wherein said material includes antibacterial ingredients to form an outer layer of said mask.

### Claim 8 (depends on 7)

The method of claim 7, wherein said antibacterial ingredients include lysozyme.

### Claim 9 (depends on 7)

The method of claim 7, wherein said antibacterial ingredients include anti-influenza medicine.

### Claim 10 (depends on 6)

The method of claim 6, wherein an aperture of said ultra-micro-perforated filtering membrane is between about 0.03 μm and about 15 μm.

### Claim 11

(canceled)

### Claim 12 (depends on 6)

The method of claim 6, wherein a thickness of said ultra-micro-perforated filtering membrane is about 8˜50 μm.

### Claim 13 (depends on 6)

The method of claim 6, wherein said ultra-micro-perforated filtering membrane is polytetrafluoroethylene (PTFE).

### Claim 14 (depends on 1)

The method of claim 1, wherein said material includes scent molecules to form an inner layer of said mask.

### Claim at position 15

˜20. (canceled)
