“…UV protection properties were positively affected by XPs treatment. In fact, XPs treatment can improve the UV protection properties on nanofunctionalized surfaces via covering certain parts of bigger nanoroughness followed by reducing irregular multi-internal reflections [ 48 ], increasing the reflection proportion against light transfer [ 47 ], inducing light to the TiO 2 and clay nanostructures as the UV-absorbent, and increasing the absorption proportion against light transfer.…”

This paper deals with the engineering multicomponent nanofunctionalization process considering fundamental physicochemical features of nanostructures such as surface energy, chemical bonds, and electrostatic interactions. It is pursued by modeling the surface nanopatterning and evaluating the proposed technique and the models. To this end, the effects of surface modifications of nanoclay on surface interactions, orientations, and final features of TiO2/Mt nanocolloidal textiles functionalization have been investigated. Various properties of cross-linkable polysiloxanes (XPs) treated samples as well as untreated samples with XPs have been compared to one another. The complete series of samples have been examined in terms of bioactivity and some physical properties, given to provide indirect evidence on the surface nanopatterning. The results disclosed a key role of the selected factors on the final features of treated surfaces. The effects have been thoroughly explained and modeled according to the fundamental physicochemical features. The developed models and associated hypotheses interestingly demonstrated a full agreement with all measured properties and were appreciably confirmed by FESEM evidence (direct evidence). Accordingly, a guideline has been developed to facilitate engineering and optimizing the pre-, main, and post-multicomponent nanofunctionalization procedures in terms of fundamental features of nanostructures and substrates for biomedical applications and other approaches.

“…The results show that the water droplet absorption time was increased nearly 300 times following TiO 2 functionalization. The hydrophobicity of the treated sample increased after washing due to the removal of Ps emulsifiers [16].…”

“…The positive effect of XPs is likely due to the fact that a network-like layer of polysiloxane forms on the fabric surface. XPs can also allow easier movement of polymer chains due to a plasticizing effect which results in easier polymer chain movement and crease recovery [16]. Wrinkle recovery angle is especially important in garment applications of silky PET fabrics.…”

Providing an even nano-finishing via pad-dry process as the simplest finishing method on ultra-fine silky PET fabrics is difficult due to low absorption potential, extremely low friction resulting in pad mangles and the low thickness. This research aims to develop a procedure of continuous nanofunctionalization of ultra-fine silky PET fabrics and examines their properties. An as-prepared TiO 2 nanocolloidal solution was applied to fabrics by means of a continuous pad-dry process. To stabilize the nanostructures on the fabric surfaces, the samples were subjected to a simple and fast aftertreatment. The effects of this treatment were assessed on washing stability, water repellency (contact angle and droplet absorption time), handle (bending length), wrinkle resistance, UV protection properties and wear properties. An even nano finish on the ultra-fine silky PET fabric was confirmed by SEM micrographs with different magnifications. Results indicate an enhancement of water droplet absorption time as well as the contact angle of droplets on the treated samples which corroborates increased hydrophobicity. Additionally, the treatment enhanced softness, wrinkle resistance and particularly washing fastness of the nanofunctionalized fabrics. The results demonstrate that the functionalization improves the wear properties and the UV stability of the treated fabrics.

In this study, the effect of using folic acid on the in situ synthesis process of nanostructures has been investigated. Folic acid, as a biotemplate for synthesis of Cu2O/ZnO, was used to improve the reducing and stabilizing the ability of cotton fabric and avoid agglomeration of the particles. Scanning electron microscopy images revealed that using folic acid caused the formation of particles with smaller sizes on the cotton fabric and X‐ray diffraction confirmed the same crystalline pattern of nanoparticles in comparison with the previous synthesis process. The effect of using this biotemplate on different properties of treated fabrics including UV‐protection effect, hydrophilicity, crease recovery angle, softness, thickness and mechanical properties has been evaluated. The folic acid had a great influence on UV‐protection effect, in synthesis procedure, decreasing the droplet absorption time, bending length and improving the wrinkle resistance and mechanical properties. Interestingly, the higher tensile strength of the treated cotton fabrics proved the incorporation of nanoparticles into the cotton fibers. An in situ, green and rapid method can be provided by using folic acid for the synthesis of the nanostructures with controlled size.
