In the present study, natural dye from cob of purple corn and various metallic salts have been used to identify the proper dyeing condition for attaining high quality natural dyeing along with imparting UV protection property to the dyed silk fabric. Silk fabrics dyed with cob of purple corn extract showed a violetish-pink shade, while those dyed with alum light violetish-pink shade colour. Silk substrates dyed with CuSO4 and FeSO4 gave a yellowish grey and violetish-gray colour, respectively. The fastness properties ranged from fair to good. The ultraviolet protection factor (UPF) values of silk fabric dyed with and without metal mordants ranged between very good and excellent.

Three types of hydrosol including TiO2hydrosol, ZnO hydrosoland TiO2/ZnO compound hydrosol prepared at room temperature by sol-gel technology were applied to cotton fabric by pad-cure-dry finishing process in order to improve UV-protection property. The SEM image showed that all the three types of sol formed a thin layer film on the cotton fiber. The results of UV-protection property tests showed that with the TiO2sol and TiO2/ZnO compound sol, the cotton fabric have better UV-protection property, but the cotton fabric finished by ZnO sol didnt get little UV protection property. The fastness of UV-protection performance by soaping was also researched in this paper. The test results justified that the soaping process after finishing was a very useful and helpful process to improve the UV-protection property. The cotton fabric finished by ZnO sol after 50 times soaping got better UV-protection property than that without soaping. The UV-protection property of cotton fabric finished by TiO2/ZnO compound sol was also improved dramatically similarly after 50 times soaping. The fabric finished by TiO2sol got best UV-protection property in the three types of fabric without soaping and the UV-protection of it after 30 times soaping raised to peak value but decreased with longer soaping times.

Montmorillonite Nanoclay

In this study, the layered nanoclay was employed to impart ultraviolet (UV) protection functionality for electrospinning thermoplastic polyurethane (TPU) nanofibrous mats. This study is among the very rare studies which uses Montmorillonite (MMT) clay for UV protection. Due to its known UV protection property, titanium dioxide (TiO2) was used solely for comparison with MMT clay and as a blend with MMT for investigation of its synergetic effect with nanoclay. The morphology and chemical structure of virgin and nanoclay-loaded nanofibers were characterized via Scanning Electron Microscopy (SEM) and Fourier Transform Infared Spectroscopy (FTIR). Incorporation of TiO2 significantly improved UV protection performance of TPU electrospun nanofibers, as expected. UV protection factor (UPF) of electrospun mats including nanoclay was found as high as that of the ones including TiO2.Therefore, the study revealed that the clay has a considerable potential for producing nanofibrous layers with UV protection. Such a nanocomposite structure could be potentially employed as a layer in a multilayered technical textile such as tents, sun protective covers for automobiles, blind curtains, etc. This study proposed an eco-friendly and viable alternative to TiO2 which is a well-known material for its UV protection.

Protection against ultraviolet radiation is one of the areas, in which considerable attention is being paid. Application of a wash durable finish on cotton fabric to protect the wearer from these radiations remains a challenge. The harmful effects of UV radiations result in the form of eye disorders, accelerated ageing of skin, DNA damage and cause of cancer. The current study focuses upon the use of TiO2 on cotton fabric to impart UV protection. TiO2 is deposited on cotton fabric using its pre-cursor. Sol-gel method has been used to convert pre-cursor into titanium oxide directly on fabric surface. The deposition was further stabilized on fabric surface by various heat treatments such as curing, hydrothermal and solvothermal treatments. It has been found that the TiO2 remains wash durable with a reasonably high degree of UV protection after hydrothermal and solvothermal treatments. EDX and ICP-MS techniques were used to examine the add-on % of TiO2 on cotton fabrics. The morphology of the TiO2 coated cotton fabric was studied using Field emission scanning electron microscopy. The measurement of UV protection property of the fabric has been carried out using UV-visible spectrophotometer (UV-2000F, Labsphere, USA).
