Abstract

A process for treating leather is provided that contours leather fabric by applying a high heat, low oxygen, heat source capable of maintaining constant temperature, to leather at an angle that creates a valley in the leather at the point of application of the heat source and curls the leather surrounding the heat source upward. The process may further include blasting the leather with sand or beaded glass to lighten the color of the original leather fabric and create a worn or distressed look. The process may further involve dying the leather after the leather has been distressed. Optionally, the process may also include applying a light coating of lanolin oil to add moisture to the leather after it has been treated.

RELATED APPLICATIONS

This application is a continuation of U.S. Design patent application Ser. No. 29/164,929 titled “Fabric” filed Aug. 8, 2001, which is incorporated into this application by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates generally to a leather treatment process and, in particular, a thermal process for treating leather to create decorative effects.
2. Related Art
Fashion is an important aspect in society. Fashion designers are under continually pressure to create and introduce new and desirable fashion designs. Thus, a continually need exists for new fabrics and new decorative designs to satisfy the demands of the fashion industry.

SUMMARY

A process for treating leather is provided that contours leather fabric by applying a high heat, low oxygen, heat source capable of maintaining constant temperature, to leather at an angle that creates a valley in the leather at the point of application of the heat source and curls the leather surrounding the heat source upward.
The process may further include blasting the leather with sand or beaded glass to lighten the color of the original leather fabric, creating a worn or distressed look. Optionally, the leather may be dyed after it is distressed. Additionally, the process may further include applying a light coating of lanolin oil to add moisture to the leather after it is treated.

DETAILED DESCRIPTION

A new redesigned leather fabric is created from an existing cowhide, buffalo, goat, sheep or lambskin. The applied technology will sculpt and contour the leather to create a reversible bubble leather design ready for use in the marketplace.
As illustrated in FIG. 1, a thermal source 100 may be used as the contouring element and be a curved torch 102 with a very consistent heated tip 102. Store bought tips 102 maybe used by altering the configuration of the tips 102 so that the tips 102 are angled to approximately a 45 degree angle. At this angle, the heat flows from the tip 102 and disburses the flame (not shown) as a side split flame, thereby allowing the leather to be curled and then bonded. FIG. 2 illustrates an enlarged view of the tip 102 of the heat source 100 configured at a 45 degree angle. Because of the nature of the composition of leather hide, it is easily burned if the proper tip 102 is not used by the heat source 100. As illustrated in FIG. 1, the process may use the mixture of gasses 104, such as propane 106 and oxygen 108, to ignite the flame tip when the pin pointed flame hits the leather in order to create a deep valley and seal the bubble around it. The process used may be a high heat, low oxygen process.
FIG. 3 illustrates one example of a heat application pattern that may be used to apply the heat source to the leather and indicates where the raised areas will develop following this pattern. In other words, after the heated tip has passed the circular pattern (left to right) 302 in slow or fast circular motions over the leather 300, a small medium or large bubble 304 will form in an upward direction and then be sealed and retain that shape.
FIG. 4 illustrates a perspective view of one example of the appearance of leather fabric 400 after application of the heat source using a similar pattern to FIG. 3. In FIG. 4, the raised bubbles are illustrated as 402. FIG. 5 is a top view of the leather fabric 400 illustrated in FIG. 4.
FIGS. 6-8 illustrate other example heat application patterns used to apply the heat source and the resulting contour. FIG. 6 illustrates how the heat source may be applied in a continuous pattern that cuts through the fabric, creating a cut-through design. The leather fabric 600 is contoured by applying the heat source along the pattern line 602 in direction indicated by the arrows.
FIG. 7 illustrates the application of the heat using parallel pattern lines spaced across the leather fabric in two directions. The leather fabric 700 is contoured using parallel, generally evenly spaced pattern lines across one axis of the fabric 702. Opposing parallel, generally evenly spaced pattern lines 704 are also provided across the fabric 700 along the axis perpendicular to the axis of pattern lines 702. By applying the heat source along these pattern lines 702 and 704, raised bubbles 706 would form, creating a raised checker board type design on the leather fabric.
FIG. 8 illustrates the application of a random flowing pattern design. The leather fabric 800 is contoured by applying the heat source along the pattern line 802 in the direction indicated by the arrows. Using this pattern for applying the heat source, raised bubbles 804 will form on the leather 800. The bubbles in the leather fabric are created as a group of locks that formed from the heating process, which pushes the leather upward to form the bubble. The application of the heat source in a quick straight-up motion to the pattern illustrated in FIG. 8 may be used to seal and form the bubbles. Such a flowing application pattern of the heat source can be applied to other areas of the fabric to continue the treatment processes. Further, the heat source may be applied to the bubbles created in the leather, which will result in other raised patterns (not shown) such as diamonds, squares, lines and images. Lines or valleys in the leather will form separate flow patterns. As illustrated, various bubble patterns may be created in various shapes and sizes, adjustable to any size or pattern and limited only by an artist's imagination.
In operation, the application of the high heat, low oxygen treatment shrinks the leather material when applied, which allows for the sculpting or contouring of the leather fabric. When contouring fabric for a specific purpose, consideration should be giving to the fact that the process will shrink the leather. For example, a process creating raised bubbles up to 2″ in diameter may shrink the leather fabric 2 to 4″ depending on the height and width of the leather fabric and the contouring process.
The contoured leather fabric created using the present invention creates a finished fabric. Further, either side of the contoured leather may be used. The contouring process is applied to the display side of the fabric. The opposing side of the fabric appears as the reversal of the raised bubbles, which appears as dimples or craters in the suede side of the leather. Because the reversed side of leather provides a suede finish, either side of the leather may be displayed and used as a contoured fabric. Products can be made displaying either side of the contoured fabric.
Optionally, the contoured leather fabric may be further treated to create a distressed leather look. The distressed leather look may be created by blasting the contoured fabric with powered sand or beaded glass. A light blasting spray can lighten the color of the leather fabric and create a new look from the original dye. Applying this distressing technique to the treated or contoured leather causes solid colors to become disbursed, breaking line out of color and fading after the blasting process is completed. One can then re-dyed the distressed fabric. This process can be performed on non-contoured leather. The contouring may then be performed after the leather is distressed. Additionally, after the leather is contoured, a light coating of lanolin oil may be applied to add moisture back into the leather fabric.
The foregoing description of an implementation has been presented for purposes of illustration and description. It is not exhaustive and does not limit the claimed inventions to the precise form disclosed. Modifications and variations are possible in light of the above description or may be acquired from practicing the invention. The claims and their equivalents define the scope of the invention.
