ABSTRACT

With the continuous social development and progress, people impose increasing higher functional requirements for clothing. Coated fabrics thus came into being. At present, research on sweat latent fingerprints on fabric is mostly based on traditional fabric materials and relatively lags behind. In view of this, common PVC, PU, PA and PTFE coated fabrics were selected as bearing bodies of sweat latent fingerprints in this paper. Through series of experiments, it was found that coated fabrics were different from conventional fabrics, whose sweat latent fingerprints could be treated and developed by traditional powder development method and "502" glue fumigation method. However, ninhydrin development method is not suitable for the development of sweat latent fingerprints on the above four kinds of coated fabrics. This study serves as a preliminary exploration for latent fingerprint development on coated fabrics.
