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.

Study Results

Ecological and economic responsibilities have led to the search for alternative material applications in the textile sector as well as in all sectors. Sol-gel technology is one of these applications with advantages such as realization under low temperatures and enabling the desired product shape and format. In this study, the samples of 100% cotton fabric have been processed by using pigment printing technique with natural pumice, amorphous silica and colemanite materials and printing fixation process has been performed by using the sol gel coating method. The sol gel treatment has been carried out with basic catalyst according to the zeta potentials of the solid particulate materials used. After the new created process, surface morphologies, EDS point analysis and F-TIR analysis of all fabric samples have been performed. In addition, the properties such as strength, UV protection, air permeability, water permeability, abrasion resistance, flammability of all fabrics have been investigated. The results of surface analysis have proven that the chemical components of the natural materials are transferred to the fabric samples. It has been proven by the test results that all cotton fabric samples are given high strength, UV protection, flammability, high abrasion resistance and low air permeability. Interpretation of all the analysis and obtained test results has been also made statistically. According to the study results, ecofriendly process step has been created that allows low energy cost and low chemical usage under low temperatures

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).

Methods for polymerizing triallyl phosphate on a cotton fabric were examined under conditions feasible for application in a commercial radiation textile finishing process. Although triallyl phosphate does not polymerize with irradiation at low dose levels at room temperature in air under the specific conditions described, it was found that copolymerization of triallyl phosphate with acrylic acid derivatives can be used to produce flame-resistant cotton fabric. A cotton fabric treated with triallyl phosphate and N-methylol acrylamide and exposed to 2 megarads of radiation from high-energy electrons, in air at room temperature produced a flame-resistant fabric durable to 15 accelerated cotton mobile launderings.

In the present study, cotton fabric has been dyed with natural indigo (Indigofera tentoria) in absence and present ferrous sulfate mordant by using post-mordanting and pad-batch processes. It was observed that with an increase in the dye concentration, the ultraviolet (UV) protection factor (UPF) values good for the cotton fabric. Cotton fabrics dyed with natural indigo showed greenish-blue shade. The fastness properties ranged from good to very good, level. The results confirmed that natural dyes from natural indigo with ferrous sulfate have potential applications in fabric dyeing and in producing UV-protective cotton fabrics.

AbstractPhotoresistant laser dyes were trapped in silica based xerogel host matrices to obtain solid state tunable lasers. For this purpose very dense xerogel samples with improved chemical and physical properties were prepared at room temperature by the sol-gel technology. The as-prepared materials were polished to obtain optical quality surfaces and were used as new lasing media.Lasing action of such different dyes as rhodamine, perylene and pyrromethene doping dense sol-gel matrices was demonstrated. Efficiencies of 30 % or lifetimes of more than 100,000 shots were achieved with different new ≤dye dopant/host matrix≥ couples. Their different performances are reviewed and discussed.

Introduction:: MCM-41 was synthesized using the sol-gel method. Then two new transition metal complexes of Nickel (II) and Vanadium (IV), were synthesized by immobilization of adenine (6-aminopurine) into MCM-41 mesoporous. The compounds have been characterized by XRD, TGA, SEM, AAS and FT-IR spectral studies. Using these catalysts provided an efficient and enantioselective procedure for oxidation of sulfides to sulfoxides and oxidative coupling of thiols to their corresponding disulfides using hydrogen peroxide at room temperature. Materials and Methods:: To a solution of sulfide or thiol (1 mmol) and H2O2 (5 mmol), a determined amount of the catalyst was added. The reaction mixture was stirred at room temperature for the specific time under solvent free conditions. The progress of the reaction was monitored by TLC using n-hexane: acetone (8:2). Afterwards, the catalyst was removed from the reaction mixture by centrifugation and, then, washed with dichloromethane in order to give the pure products. Results:: All the products were obtained in excellent yields and short reaction times indicating the high activity of the synthesized catalysts. Besides, the catalysts can be recovered and reused for several runs without significant loss in their catalytic activity. Conclusion:: These catalytic systems furnish the products very quickly with excellent yields and VO-6AP-MCM-41 shows high catalytic activity compared to Ni-6AP-MCM-41.

Thin films nanoparticles TbxY3-xFe5O12 (x=0.0, 1.0, 2.0) were prepared by the sol-gel process followed by annealing process at various annealing temperatures of 700° C, 800° C and 900° C in air for 2 h. The results obtained from X-ray diffractometer (XRD) show that the films annealed below 900°C exhibit peaks of garnet mixed with small amounts of YFeO3 and Fe2O3. Pure garnet phase has been detected in the films annealed at 900°C. Before annealing the films show amorphous structures. The particles sizes measurement using the field emission scanning electron microscope (FE-SEM) showed that the particles sizes increased as the annealing temperature increased. The magnetic properties were measured at room temperature using the vibrating sample magnetometer (VSM). The saturation magnetization (Ms) of the films also increased with the annealing temperature. However, different behavior of coercivity (Hc) has been observed as the annealing temperature was increased.
