Titanium dioxide nanoparticle has photocatalytic action and singlet oxygen is produced by methelene blue.
Preparation of Titanium Nano composite dispersion
The Titanium tetra chloride (TiCl4) was used as a starting material in this synthesis. 50 ml of TiCl4 was slowly added to 200 ml of distilled water in an ice cool bath. The beaker was taken from the ice bath to room temperature. The beaker was kept in magnetic stirrer to get a homogeneous solution. Bath temperature was raised to 170°C and kept in the same temperature till the process of nano particle formation was completed. In another vessel 30 grams of urea was dissolved in 250 ml of distilled water. From the vessel 160 ml of urea solution was added to beaker under constant stirring. The solution turned into white colloid without any precipitation. 25 grams of Methylene blue was added to the titanium nano particles.
Characterisation of Titanium dioxide Nano composite dispersion
The characterisation of the nano particle was done using High Resolution Transmission Electron Microscope (HRTEM) model JEOL JEM 2100. The HRTEM confirms the average size of nano particles.

A 5×5mm swatch was cut from the nonwoven felt. Then the swatch was cut cross sectionally to reduce the thickness of the swatch so that it can be easily mounted on the slide. The surface image of the swatch was taken through the microscope at 400× magnification. Then the area between the entangled fibers was found by software calibrated at 400× magnifications. The average area of 100 readings was determined.

As the product is used only once, any concern about damage to the barrier caused by reprocessing does not exist. Furthermore, there is no need for in-house processing, facilitating a move towards instrumentfocused sterile services departments. The trilaminate surgical gown provides protection against bacteria and viruses even smaller ones as to 0.Energy Saving Manufacture Detox Foot Patch for Good Sleeping.Pure Material HDPE Poly Pipe for Water Supply and Drains-contamination between medical staff and patient's body fluids. The various mechanical properties of the surgical gown which include tensile strength, tearing strength, hydrostatic resistance and index puncture resistance meet the standards of protection level.
33kv High Voltage Outdoor Gang Isolator Switch / Disconnect Switch. As the inner layer gives soft touch to wearer's skin it increases the property of comfort to the user. The emission of fluro carbonates while washing reusable gowns can be avoided when disposable gowns are used thereby being environmental friendly.
Only 2% hospital waste is contributed by disposable gowns. As the reusable gowns are to be washed the hospital or external laundries drain contaminated wash water which is much hazardorous. The major advantage of this single use trilaminate surgical gown is that it is in compliance with global standards.
Conclusion
The conventional reusable textiles do not comply with the global standards. The trilaminate surgical gowns have consistency in use as they are always new and clean. Hence there is no need of Compromise during laundering.
