Abstract:
Microencapsulation is a process in which tiny particles or a coating to give small capsules with many useful properties surrounds droplets. 'Small is better' would be an appropriate motto for the many people studying microencapsulation. In its simplest form, a microcapsule is a small sphere with a uniform wall around it. The material inside the microcapsule is referred to as the core, internal phase, or fill, whereas the wall is sometimes called a shell, coating, or membrane. Wound healing is a natural process and dressing and medication enhance the process. There has been a sharp increase in the use of wound dressing materials in the recent past. Preparing an adhesive tape that is made of 100% natural bamboo non – woven materials which has been encapsulated with herbs like coffee and green tea for a better antibacterial activity. Coffee and green tea extract were encapsulated to get a better result and also they were tested for antibacterial activity, the outer shell used was sodium alginate. Where the top layer is having a PP laminated and the adhesive used is water based adhesive. The study shows that 100% bamboo nonwoven materials treated with coffee shows the maximum antibacterial activity when compared to 100% bamboo nonwoven material when treated with green tea. There was no allergic reaction seen on skin when tested with the entire two samples on different age and different skin type.
