DESCRIPTION:
BRIEF SUMMARY
FIELD OF INVENTION
The present invention relates to an improved method for producing a multi-colored emblem having the appearance of being sewn on a garment which is easily heat-sealable to another fabric and more particularly the emblem is readily fastenable to difficult to adhere to fabrics such as siliconized nylon, Gortex, polypropylene, tri-acetate, and Lyrca.
BACKGROUND ART
Emblems such as letters and numbers having embroidered edges have been popular for use on sporting uniforms and jackets for many years. Often the embroidery is the only way in which the letters and/or numbers can be secured to garments made from hard to adhere to materials such as siliconized nylon, Gortex, polypropylene, tri-acetate and Lycra. The nature of these fabrics make it very difficult for any adhesive to penetrate the fabric and form a good bond between the letters or numbers and the garment.
Heat sealing has allowed prestitched letters and numbers, giving an embroidered appearance, to be bonded to garments made from easy to adhere to fabrics such as twill, cotton, fleece, and silk. U S. Pat. No. 3,816,211 discloses a method for making an embroidered emblem which has a fabric base with an embroidered design on the base and a thermoplastic material laminated to the base. The emblem is fastenable to a garment by conventional heat sealing. The emblem is not heat sealable onto difficult to adhere to fabrics.
U.S. Pat. No. 4,517,910 discloses an embroidered design for securement to an article in which the design is embroidered on a substrate made of woven polyester fabric. The substrate is bonded to a low-melt thermoplastic adhesive film to form a lamination. The design is traced along its outer and inner peripheries to remove all portions of the lamination, except the design consisting of the embroidering thread and the plastic film. The design is then heat sealed to a garment to simulate a design embroidered directly on the garment.
DISCLOSURE OF INVENTION
An object of the present invention is to provide a method for providing a multi-colored emblem having an edge stitched or embroidered appearance which is easily heat sealable onto difficult to adhere fabrics and/or garments and eliminate the sewing and thereby the expense associated with securing an embroidered emblem to a difficult to adhere to fabric.
In carrying out the above object and other objects of the invention, the method for producing an emblem in accordance with the invention comprises the steps of providing a first woven material blank, providing a barrier layer of a thermoplastic material and laminating with the application of heat and pressure the barrier layer onto one side of the material blank. The material blank with barrier layer thereon is cut to the configuration of the emblem to be produced and is then sewn about the periphery of the cut material blank to produce an embroidered appearance. A second woven material blank of a color contrasting with that of the first blank and provided with a similar barrier layer is cut to a complimentary but larger configuration than the first blank and then sewn about the periphery to produce an embroidered appearance. The two material blanks are heat sealed together leaving the barrier layer of the second blank material exposed Then an adhesive layer of an uncured linear saturated polyester in combination with a heat activated curing agent having a paper carrier is applied to the exposed barrier layer.
The adhesive layer has a lower melting temperature than the barrier layer whereby the adhesive layer is unable to pass through the barrier layer The adhesive layer, which has the capability of penetrating the interstices of a fabric against which it is adhered, will discolor or deface the emblem if applied directly thereto Thus, the barrier layer allows the embroidered appearing emblem to be conventionally heat sealed to difficult to adhere to materials such as siliconized nylon, Gortex, polypropylene, tri-acetate and Lycra and when adhered looks as if the emblem has been sewn onto the material.
