Abstract
Abstract Threads extend through apertures of a button and into a fabric to secure the button onto the fabric. A protective abrasionresistant cap is formed over the thread portions which cross the face of the button by applying a selected bonding agent to the thread portions. Some of the bonding agent penetrates into the threads and bonds the threads together. The remainder of the bonding agent hardens around the thread portions forming a protective cap. The bonding agent is selected such that it will penetrate the threads only to desired degree leaving some of the bonding agent to form the protective cap and limiting the region of thread penetration such that the flexibility of the button mounting is preserved.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
32 words
The method of claim 1 characterized by the step of maintaining the face of the button in a substantially horizontal plane while applying the bonding agent and curing said impregnated thread portion.
Claim 2
Dependent Claim
43 words
The method of claim 1 wherein said bonding agent comprises a mixture of a resin, a surface active agent to facilitate the penetration of the mixture into the threads, and an anti-foaming agent to minimize the formation of bubbles in the protective cap.
Claim 3
Dependent Claim
23 words
The method of claim 3 wherein the mixture has a viscosity with the range of 700-2100 Centipoises as measured on a Brookfiled Viscometer.
Claim 4
Dependent Claim
12 words
The method of claim 4 wherein the resin comprises a vinyl-ethylene resin.
Claim 5
Dependent Claim
13 words
The method of claim 1 wherein the bonding agent comprises a thermosetting resin.
Claim 6
Independent Claim
106 words
A method of prolonging the service life of threads securing a button to a fabric without destroying the flexibility of the mounting comprising the steps of applying a bonding agent consisting of a resin, surfactant, and an anti-foaming agent to the thread portion extending across the face of the button between the spaced button apertures, controlling the degree of wicking of said bonding agent along the button threads by regulating the amount of surfactant present in the bonding agent to permit impregnation of said thread portion while preventing impregnation of the button threads extending below the button thereby forming a protective cap encompassing said thread portion.
Claim 7
Dependent Claim
13 words
The method of claim 7 wherein the bonding agent comprises a vinyl-ethylene resin.
Claim 8
Dependent Claim
13 words
The method of claim 7 wherein the bonding agent comprises a thermosetting resin.
Claim 9
Dependent Claim
29 words
The method of claim 7 wherein the resin comprises vinyl-ethylene copolymer and the mixture has a viscosity within the range of 700-2100 Centipoises as measured on a Brookfield Viscometer.
Claim 10
Dependent Claim
15 words
The method of claim 1 wherein said bonding agent is heated during said curing step.
