The flame-retardant treatment of polyester fabrics has been widely reported, but most of these treatments cause a significant decrease in the fabric’s handle, such as fluffiness and softness. This study designed and synthesised a new phosphorus-nitrogen-containing silicone oil (PNSO). Then, PNSO as a flame-retardant was treated on polyester fabric through a pad-dry-cure procedure. The limiting oxygen index (LOI), afterflame time and damaged length of the finished polyester fabric (PNSO-F) were enhanced from 20.5%, 73.1 s and 26.8 cm to 28.3%, 4.5 s and 12.3 cm, respectively. After 12 washes, PNSO-F retained its good flame-retardancy and anti-dripping properties. Furthermore, the flame-retardant mechanism of PNSO on fabric was investigated using different spectral methods , which revealed that nitrogen acting in the gas phase, and phosphorus and silicone in the condensed phase worked together to produce a synergistic flame-retardant effect. In addition, KES tests indicated that the fluffiness and softness of PNSO-F were significantly improved.

Electromagnetic shielding fabric (ESF) is a novel electromagnetic shielding product with portability, flexibility, and good mechanical properties. However, the existing ESFs suffer from poor washing fastness of coating and poor comfort performance in terms of hand-feel characteristic. In this study, a core layer-coated yarn (CLCY) was successfully spun using a carboxylic acid-functionalized multi-walled carbon nanotube/polypyrrole/Fe3O4 composite suspension with polyvinyl butyral as an adhesive agent. To better explore the properties, the original fabric and treated fabrics, viz., core layer-coated fabric (CLCF) and surface layer-coated fabric (SLCF), were characterized by several methods. Scanning electron microscopic observations revealed that the coating was on the core layer in CLCF. In addition, the Fourier-transform infrared spectroscopy and X-ray diffraction spectroscopy results revealed that the composition of the coating corresponds with that in the multi-composite suspension. Moreover, the coating of CLCY formed a conductive path with good conductivity in the core layer, but the conductivity of the coating on the surface layer of SLCF deteriorated sharply after washing. Further, compared with the original fabric and SLCF, CLCF has highest breaking strength (after 10 washes), and keeps a relatively good hand-feel characteristic. Finally, the evaluated electromagnetic interference shielding characteristics reveal that the fastness of coating affects the electromagnetic shielding effectiveness, suggesting that the wrapped protection of outside staple fibers in CLCF reduce the loss of coating in the core layer during washing. However, the coating on the surface layer in SLCF could be washed away easily.

Graphene not only provides functional finishing for fabrics, but also influences the original physical and mechanical properties of the fabrics, reducing their wearing properties. This study conducted graphene conductive finishing on acrylic/wool blended knitted fabrics using an oxidation–reduction method. The research focused on analyzing the reduction of graphene, fabric conductivity, thermal comfort, and hand feel of the fabric, while studying the effects of reduction temperature and time on electrical conductivity, thermal comfort, moisture absorption, breathability, and hand feel during the graphene process. The results revealed that a higher degree of graphene reduction led to lower surface resistance and enhanced electrical conductivity in the acrylic/wool blended knitted fabrics. The stability of the fabric structure and mechanical characteristics were also influenced by temperature and time, impacting comfort attributes. The reduction temperature and duration directly influenced the reduction degree of graphene, with the maximum reduction degree and lowest surface resistance observed at 75 °C and 90 min. Importantly, there was no significant degradation in the thermal comfort and tactility of the acrylic/wool blended knitted fabrics.

A new photocurable coating process that combines ultra violet light emitting diode (UV-LED) and deliberately synthesized photocurable polyurethane acrylate (PUA) was developed in this study. The structures of the PUA were characterized by attenuated total reflectance flourier transformed infrared (ATR-FTIR), porton nuclear magnetic resonance ( 1 H NMR) and gel permeation chromatography (GPC). The structure-activity relationship of such PUA was studied by rheological measurements, photopolymerization performance, and mechanical tests. By adjusting the molecular weight and the number of functional groups in the PUA, balanced the wear resistance and flexibility of the photocured coatings were achieved. The optimal formula for photocurable coating was obtained as follows: the R-value (the molar ratio of –NCO/–OH) of PUA was 1.3, the ratio of PUA/HEA (2-hydroxyethyl acrylate) was 60 wt%/40 wt%, and the ratio of end-capped agent HEA/PETA (pentaerythritol triacrylate) was 2/1. With the optimized photocurable coating formula, textile artificial leathers were fabricated and exhibited excellent colorfastness to rubbing, and Martindale abrasion resistance and satisfied fabric handle.
