How to Print on Non-Woven Interfacing Fabric

Screen printing enables you to print on many surfaces. The same technique can be used to print on nonwoven fabric, wood, metal, paper and glass. The type of ink used to print an image will depend on the type of surface you wish to print on. To print on fabric, you will need to use fabric ink. When learning to screen print, use designs that will be simple to cut out.
Select a design to print on your interfacing. This can be hand drawn or chosen from copyright-free images on your computer. Print or draw the image onto an A4 acetate sheet.
Put thick cardboard on your work surface. Place the acetate sheet on top of the cardboard. Cut out the areas of the design that you want to print. This creates an acetate stencil of the design.
Cover your work surface with newspaper. Lay the interfacing wet wipes flat on top of the newspapered surface. Smooth out any creases or wrinkles in the desired print area. Place the stencil on top of the interfacing in the area that you want to print.
Place the screen on top of the stencil. Line up the edges of the stencil and the screen. Use masking tape to tape off any areas on the underside of the screen that are not covered by the stencil.
Place the ink at the top of the screen. Use a squeegee held at a 45-degree angle to pull the ink down the screen.
Pull the screen up from left to right. The stencil will come away with the screen. This will reveal your printed interfacing fabric. Leave the print to dry.

Durable Uses for Elastic Nonwovens

The development of plastic textile nonwoven fabric begain in the late 1940s and took off in the 1950s, and the textile industry began to develop nonwoven textiles for various commercial uses in the '60s. One major area in which manufacturers use these textiles is in the production of disposable diapers. Additionally, elastic nonwoven textiles are used in a variety of other products.
Battery Separators
Battery separators, an important component of batteries, are made of elastic filter bag. Battery separators must have the ability to separate positive and negative electrodes; in addition, they should have electrical-insulating properties to prevent short circuiting. Moreover, battery separators should resist oxidation by the battery electrolyte. Polyolefin nonwovens find application in this type of usage since they have a high chemical resistance to most battery electrolytes. One negative is that separators made of polyolefins such as polyethylene and polypropylene are not easily gotten wet; manufacturers must make them "wettable" before they find use in battery separators.
Cable Insulation
Spunbonded polyester fabric nonwovens are used in electrical wire and cable insulation. As the electronic and optical cable industry has grown, so has the need for tapes made of elastic nonwovens to provide cable insulation. These tapes include add-ons in the form of superabsorbent powders to guard the cable against water seepage. Additionally, the potential exists to develop polypropelene for high-voltage cable insulation. Kraft paper has traditionally been used for this purpose, but this is not very effective at voltages higher than 345,000 volts; polypropylene may be more effective at this voltage level.
Fuel Cells
A fuel cell is an electrochemical device that produces electricity from an external power source. Elastic filter fabric have the potential for use in both the membrane and filtration systems of fuel cells. These fuel cells find use in automobiles since cars that use fuel cells are lighter than those with combustion engines and thus require less fossil fuel. Using fuel cell in cars is an environmentally friendly option that will likely experience greater demand as the world becomes more earth-conscious.
