Abstract
Cooperative touch fasteners have a sheet-form base with an upper face and a lower face. Extending outwardly from, and integral with the upper face of the base is a plurality of fastener elements. Additionally, the lower face of the sheet-form base has a pressure adhesive property and is coated with a cross-linkable adhesive. The cooperative touch fasteners can be used to alter garments, hang window coverings and attach finishing covers. Additionally, the fasteners can be used in place of snaps and buttons, in medical devices, with diapers and in conjunction with a variety of manufacturing techniques.
Claims85
A touch fastener comprising:
- a sheet-form base having an upper face and a lower face;
- extending outwardly from the upper face of the base, a plurality of discrete fastener elements;
- and
- the lower face including an adhesive layer having a pressure-sensitive portion, and comprising a cross-linkable adhesive
A method of permanently bonding a touch fastener to a material, the method comprising:
- providing a touch fastener having a sheet-form base having an upper face and a lower face and a plurality of discrete fastener elements extending outwardly from the upper face of the base, the lower face including an adhesive layer having a pressure-sensitive portion and comprising a cross-linkable adhesive;
- pressing the touch fastener against the material to temporarily adhere the touch fastener to the material in a desired location;
- and then
- cross-linking the cross-linkable adhesive, thereby permanently bonding the touch fastener to the material in the desired location
A method of positioning a touch fastener, the method comprising:
- temporarily adhering a touch fastener to a material at an initial location, the touch fastener having a sheet-form base with upper and lower faces and, extending outwardly from the upper face of the base, a plurality of discrete fastener elements, the lower face including an adhesive layer having a pressure-sensitive portion and comprising a cross-linkable adhesive;
- determining whether the initial location is a desired location for the touch fastener;
- repositioning the touch fastener as necessary to place the touch fastener in a preferred location;
- and
- upon determining that the touch fastener is in a desired location, cross-linking the cross-linkable adhesive, thereby permanently bonding the touch fastener to the material in the desired location.
A method of altering a garment, the method comprising:
- temporarily adhering a first portion of a touch fastener to one region of a garment, the first portion of the touch fastener having a sheet-form base having an upper face and a lower face, and a plurality of discrete fastener elements extending outwardly from the upper face, the lower face including an adhesive layer having a pressure-sensitive portion and comprising a cross-linkable adhesive;
- temporarily adhering a second portion of a touch fastener to another region of the garment, the second portion of the touch fastener having a sheet-form base having an upper face and a lower face and a plurality of discrete fastener elements extending outwardly from the upper face of the base of the second portion and configured to engage the fastener elements of the first portion, the lower face including an adhesive layer having a pressuresensitive portion and comprising a cross-linkable adhesive;
- determining whether the first and second portions are at desirable initial locations and repositioning either or both of the first and second portions as necessary;
- when each of the first and second touch fastener portions is in a desirable location, permanently bonding that touch fastener portion to a respective region of the fabric by crosslinking the cross-linkable adhesive of that portion;
- and
- fastening the first and second touch fastener portions together, thereby altering the garment.
