Abstract
Abstract The invention relates to decorations for application to sheet materials and comprises a decorative article, a layer of heat activated adhesive applied to a first surface of the article and a carrier sheet adhering to a second surface of the article which carrier sheet is heat stable at the temperature of activation of said adhesive whereby on positioning of the article with its adhesive surface juxtaposed the sheet material the application of heat and pressure activates the adhesive to produce bonding of the article to the sheet material per se. The invention is particularly concerned with the use of an embroidery pattern which is formed on a thermally decomposable sheet substrate by use of an embroidery pattern of thermoplastic threads on one side thereof and non-thermoplastic or high melting thermoplastic embroidery threads on the other thereof so that on the application of heat and pressure the substrate degrades and the thermoplastic threads are rendered tacky to merge with the sheet material to which the decoration is to be applied, the degradable substrate being removed with the carrier sheet after application.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
An embroidered article for application to a sheet material, comprising: an embroidery pattern embroidered on a sheet-like substrate of thermally decomposable material, said substrate comprising on a first surface thereof a design of non-thermoplastic or high-melting thermoplastic embroidery threads defining said design, and on a second substrate surface a cooperating pattern of thermoplastic threads of a heat activatable adhesive material which becomes tacky at a predetermined temperature; a heat stable carrier sheet adhesively and releasably adhered to said first surface; said article being adapted to be positioned with its second surface juxtaposed the sheet material, and upon application of heat and pressure to said carrier sheet activate said adhesive to produce bonding of the embroidery pattern to the sheet material and facilitate removal of degraded particulate matter produced by heating said substrate upon stripping of said carrier sheet.
Claim 2
Dependent Claim
138 words
An embroidered article for application to a sheet material, comprising: an embroidery pattern embroidered on a sheet-like substrate of thermally decomposable material, said substrate comprising on a first surface thereof a design of non-thermoplastic or high-melting thermoplastic embroidery threads defining said design, and on a second substrate surface a cooperating pattern of thermoplastic threads of a heat activatable adhesive material which becomes tacky at a predetermined temperature; a heat stable carrier sheet adhesively and releasably adhered to said first surface; said article being adapted to be positioned with its second surface juxtaposed the sheet material, and upon application of heat and pressure to said carrier sheet activate said adhesive to produce bonding of the embroidery pattern to the sheet material and facilitate removal of degraded particulate matter produced by heating said substrate upon stripping of said carrier sheet.
Claim 3
Dependent Claim
24 words
An embroidered article as claimed in claim 1, in which the said adhesive is a thermoplastic layer, which softens on the application of heat.
Claim 4
Dependent Claim
37 words
An embroidered article as claimed in claim 1, in which the heat stable carrier sheet comprises a non-woven fabric formed of regenerated cellulose fibers bonded together by non-thermoplastic binders having a melting point greater than 200° C.
Claim 5
Independent Claim
118 words
A method of applying embroidered designs to sheet material comprising the steps of: forming the embroidery pattern on opposite sides of a thermally decomposable substrate from substantially oppositely disposed areas of thermoplastic and non-thermoplastic embroidery threads on the said opposite sides respectively, laminating a carrier sheet to said non-thermoplastic threads, positioning the laminate into contact with a fabric with the thermoplastic threads juxtaposed to said fabric, applying heat and pressure to said carrier sheet to produce decomposition of said substrate to cause said thermoplastic threads to adhere to said fabric, and stripping the carrier sheet from the laminate to remove the degraded particulate matter produced by heating the laminate and destroying the thermoplastic threads of the embroidery design.
Claim 6
Independent Claim
118 words
A method of applying embroidered designs to sheet material comprising the steps of: forming the embroidery pattern on opposite sides of a thermally decomposable substrate from substantially oppositely disposed areas of thermoplastic and non-thermoplastic embroidery threads on the said opposite sides respectively, laminating a carrier sheet to said non-thermoplastic threads, positioning the laminate into contact with a fabric with the thermoplastic threads juxtaposed to said fabric, applying heat and pressure to said carrier sheet to produce decomposition of said substrate to cause said thermoplastic threads to adhere to said fabric, and stripping the carrier sheet from the laminate to remove the degraded particulate matter produced by heating the laminate and destroying the thermoplastic threads of the embroidery design.
Claim 7
Dependent Claim
36 words
A method of applying embroidered designs as claimed in claim 4, including the further step of applying a heat actionable adhesive to one surface of said carrier sheet which surface is thereafter applied to said laminate.
Claim 8
Dependent Claim
38 words
A method of applying embroidered designs as claimed in claim 4, including the further step of applying a pressure sensitive heat activatable adhesive to one surface of said carrier sheet which surface is thereafter applied to said laminate.
