Abstract
Abstract A disposable absorbent layer of material is attached by adhesive to a person''s scalp and to a hair piece to absorb scalp perspiration and thereby prolong effectiveness of the adhesive. The adhesive is initially protected by a sheet which is removed when the liner is to be used. In one arrangement, the absorbent material is confined between backing sheets of moisture impervious material with a pattern of holes being formed in the lower sheet to permit moisture to reach the absorbent material. In another arrangement, a liner comprises a sheet of material having a pattern of canals permanently formed in its lower surface with the canals being open to the person''s scalp to permit moisture and air circulation, thereby protecting the adhesive used to attach the liner to the scalp by adhesive.

Claim 8
Dependent Claim
91 words
A hair piece liner comprising a sheet of material having a pattern of canals permanently formed in its lower surface and opening downwardly to a person''s scalp when placed in use, the canals being open to the outer periphery of the sheet so that moisture can duct from beneath the liner and so that air can circulate beneath the liner, the lower surface of the sheet being adapted to be attached to a person''s scalp, and the upper surface of the sheet being adapted to be attached to a hair piece.
Claim 9
Dependent Claim
91 words
A hair piece liner comprising a sheet of material having a pattern of canals permanently formed in its lower surface and opening downwardly to a person''s scalp when placed in use, the canals being open to the outer periphery of the sheet so that moisture can duct from beneath the liner and so that air can circulate beneath the liner, the lower surface of the sheet being adapted to be attached to a person''s scalp, and the upper surface of the sheet being adapted to be attached to a hair piece.
Claim 10
Dependent Claim
36 words
The liner of claim 7 wherein said lower sheet is made of generally moisture impervious materials but the sheet is formed with a pattern of apertures for permitting moisture to be transmitted to the absorbent material.
Claim 11
Dependent Claim
