In this paper, we provide a systematic review of the fundamentals of textile UHF-RFID sensors techniques, materials, the brief history and the state-of-the-art of the scenario-based development through detailed summary and analysis on the achievements from the starting year of 2004 to the present time. This paper is motivated by this situation to identify the current research status. Due to the short time and low level of development, researches on the integration of textile UHF-RFID techniques and textile sensing techniques are not flourishing. Compared with conventional UHF-RFID sensors, textile UHF-RFID sensors offer the common textile features, light weight, washability and comfort. Textile radio-frequency identification operating in ultra-high frequency (UHF-RFID) sensors based on different scenarios are becoming attractive with the forthcoming internet of things (IoT) era and aging society. To aid the potential commercial utility of the outcomes of this investigation, an industrial scale inkjet printer (MS JP5 evo) was used.

In another set of experiments, the use of different ink limits indicated no obvious change of color gamut using the same print mode, which afforded an opportunity to reduce ink consumption, thus the cost in large-scale production, and minimize color bleeding. Results indicated that the pretreatment increased color intensity, improved print quality and enlarged the color gamut. In addition, 3-D color gamut analysis was undertaken using Origin software.

Emphasis was placed on evaluating the colorimetric attributes of individual and mixed inks, from color patches generated using Dr Wirth RIPMaster V11 software and on developing an approach to addressing color-bleeding problems that can occur from inkjet printing on PET. This paper pertains to characterizing the effects of a commercial pretreatment agent formulated specifically for digital printing on polyester (PET) fabric using pigment-based inks.
