Laser engraving synthetic textiles
Some synthetic fabrics such as fleece, felt or leather react very well to laser engraving, because the material will melt once processed, allowing for great contrast. Depending on the specific material, homogeneous engraving can be achieved using a Z offset of 1 to 5 mm with a resolution of up to 500 dpi.
Some textiles are not able to be laser engraved however, e.g. thin synthetic fiber materials, as the heat from the laser beam will completely melt the material when processed. The grayscale matrix is a quick and easy way to test your fabric, to see if it allows for homogeneous engraving to be achieved.
Laser cutting synthetic textiles
Laser cutting synthetic fabric provides excellent processing results, and all individual fibers merge and become sealed from the plastic content of the textile. This saves both time and money as there is no need for additional material hemming, as well as fraying is prevented. Synthetic materials can be cleanly cut (i.e. clean cut edges with no smoke residue) with the right combination of speed and power, and it is important to make sure to avoid using power that is too high and speed that is too low. We recommend a frequency between 1000 Hz and 3000 Hz for the best results.
CAUTION: Some synthetic materials (especially synthetic leathers) will often contain PVC, which is extremely dangerous and not suitable for any type of laser processing. When attempting to process these materials, hazardous chlorine gas and dust can be released, which will endanger the laser operator as well as the functioning of the machine. Here we have provided you with a detailed overview of unsuitable materials for laser processing.
