Description

The present invention relates to paper utensils or similar material.

To attach a Zuschneideschablonθ on the top position of a number of layers of textile material EAE is known in the! Textile industry to use sheet material, the 1st on the fitted one side with a light-sensitive layer and on the other side with a thermoplastisohen adhesive "

In current practice, a variety of

Stencils made of paper or other non-transparent materials according to the ropes of clothing articles, piping stencils are placed on paper or similar ^ material, which is provided on the upper side with a light-sensitive layer and on the lower side with a thermoplastic adhesive. Then a light source is switched on, the photosensitive layer is exposed and developed with moist ammonia gas. The exposed and developed diazotype material is now placed on one or more layers of textile material and attached to the first layer using a heat source, for example an iron. "The layers of textile material" can now be cut along the edges of the stencil, whereupon the material, which is provided with a Schablonentauster is "separated from äeif first layer of textile material" sound to filing, the trerden thus obtained can be prepared Belcleidungsartilcel *

Hach that described in Dutch patent specification 70,254 Process is using the photosensitive material connected to the textile material already at the time of exposure »With this method, the light source is also used for ■ Heat treatment. A disadvantage of this method is that that the light source, which, by the way, is not described in detail a very large increase in temperature (100 to

up to 120 ⁰ C). A further disadvantage is that the textile fabric connected to the photosensitive material must also be subjected to the development treatment.

Following the procedure described in German Patent Specification 1,057,450 the method of the equipped with an adhesive layer light-sensitive material is exposed and developed before _t securing takes place on the textile material by means of heat. If you use a very hot light source (for example a high pressure mercury lamp) for the exposure, you have to work very quickly so that the adhesive layer does not melt during the exposure. The development of photocopy material which is not attached to the textile can be effected by the so-called wet method; the exposed material is developed in a liquid. The dimensional stability is also jeopardized here.

Developing can also be done by the so-called dry Method can be carried out with cold ammonia gas. Special equipment is required for this purpose. You can continue with warm ammonia gas through which the material normally has to be passed very quickly. the The adhesive layer often cannot be made self-adhesive.

The present invention provides a material by which the inherent disadvantages of the methods mentioned are eliminated and a reliable reproduction of the designed Stencil can be obtained in a satisfactory manner.

The present invention relates to a material for textile dressing templates, the one on the back has a temperature-sensitive Adhesive coating that temporarily adheres to the textile fabric, and on the top a light-sensitive, have heat developed coating to form a light induced latent image of the Generate stencil. By heating the back of the stencil is brought into contact with tissue, the image developed using the template and at the same time glued the material onto the fabric.

The development of the image and the attachment of the pattern to the tissue take place in one operation.

The invention thus differs from the known methods described above, in which sheet material is used which is provided with a photosensitive layer on top and a thermoplastic adhesive layer on the bottom, in that the development of the photographically exposed material is eliminated in a separate operation

will. This has the advantage that Ice requires additional equipment required and the handling is simplified.

The following examples serve to illustrate the invention.

Example 1:

A solution of the following composition was used and dried to on the inventive material * a to produce photosensitive layer;

1.5 g of 1-methoxynaphthalene-4-sulfonic acid, dissolved in 25 ecm of water

given.

The other side of the material was temperature sensitive Equipped adhesive layer, which was obtained by applying and drying an aqueous emulsion, the had the following composition:

The thermal adhesive layer was made by covering the other Side of the material with an aqueous polyethylene dispersion, under the name "Coethylene" (= registered Trademarks) is commercially available and is available from Plastic Laber S.A. made by Bulle (Switzerland). This is a 35 $ dispersion of polyethylene in water.

The amount of substance applied can vary from about 7 to 30 g / m; preferably about 18 g / m 2 applied.

The combination of the light and heat sensitive layer with the thermoplastic adhesive layer as they are the Examples 1 and 2 show has been successfully applied to wool, cotton and polyester fabrics.

The photosensitive layers of Examples I ₁ II and III are ten or with those described in the examples Klebstoffschich- * applied like layers. The melting point or softening point of the adhesive layer is equal to or lower than the temperature required for developing the exposed photosensitive layer. Materials that were produced in accordance with the combinations mentioned resulted in clearly visible images and good adhesive properties on the textile. The separation of the textile from the reproduced material was quite satisfactory in practice.

By combining a light and heat sensitive Layer with a thermoplastic layer on the opposite eri 'side of the paper or similar sheet -

materials, a material was obtained on which, under the influence of those required for sticking to the fabric Heat at the same time the development of the latent stencil image takes place under such conditions that the textile material remains undamaged.

As described in the examples, the sheet material can be used as a cutting template for wool, cotton or polyester fabric. In use, the photosensitive surface is exposed to light under a cutting pattern original, the opposite thermoplastic adhesive coating layer being pressed against the textile fabric to be cut or against the topmost piece of a stack of textile fabric layers; the sheet material is heated in the process. The heating can be effected by infrared radiation or by a hot iron; Temperatures of about 100 to 15O ⁰ G are generally sufficient. The image of the template is developed and glued to the fabric. After cutting the fabric, the adhesive cutting template can easily be peeled off the fabric.
