With the sports season in full swing we thought you might need a little helping hand with choosing the right film for your sports and team wear applications.
At Xpres we have a wide range of films to choose from whether you’re looking for something with a full block out to go on to a dark sublimated kit or a transfer film that doesn’t require such high opacity.
Through continued research we have found that sportswear garments are generally polyester or contain a high percentage of polyester. These garments have more than likely been dyed with liquid dye or sublimation dye due to the polyester fibres being white in their original form.
More heat when applying the transfer film can affect both processes. When dye sublimation and liquid dyed products are subjected to high temperatures it restarts the reaction that took place to dye the fabric originally and sportswear films all need to be pressed at a temperature in excess of 100°c.
So what’s the solution?
Unlike standard single colour or digital print textile transfer films, sublimation block out products can prevent this dye migration from occurring. This is due to having an extra layer of block out that is sandwiched in to the film. When pressed, this layer acts as a barrier and prevents any liquid dye or sublimation dye bleeding through to the film and discolouring the transfer.
Transfer films that are suitable for application on to sports kits and team wear include Ultra Cut opaque range, Ultra Cut Turbo, Flexi Cut, Extra Flex and Sport Flex.
Some materials although not manufactured with a block out layer can boast good block out properties. This can be due to having a low pressing temperature or being a thicker film. Take a look at our Xpres opacity guidelines for more information. www.xpres.co.uk
