As the world is moving towards the sustainable way to recycle the waste and hence adding value to the waste produced. The egg shell is consisting of essential amino acids and properties which are still unexploited in various textile processing. The egg shell has proteineous matter which makes it a natural flame retardant. Cotton is the majorly used fibre in the overall textile industry. In the present study the egg shell waste was used to prepare an extract which is further applied on cotton fabric as a flame retardant. The characterization of the above egg shell powder shows it has amine group present at 1072.6 as well as at 873.56cm - C-Cl halo compound is present confirmed through FT-IR analysis. Two peaks were observed in DSC curves at 224.4 0 C and 254.5 °C. A LoI of cotton has increased to 36 at a lower concentration of 30% while that compared with the conventional cotton fabric.

Taking outdated tetracycline (an antibiotics) can cause serious side effects. Expired Tetracycline was known to be responsible for kidney impairment. There have been rare reports of renal tubular dysfunction or Fanconi-like syndrome associated with ingestion of outdated tetracycline. Therefore outdated Tetracycline hydrochloride drug should be thrown out or discarded if there is any leftover. Discarding unused, outdated or expired tetracycline hydrochloride in the toilet is a common practice. But this method may not be any safer than throwing in the trash, because it still is contaminating water supply. Deposing of such drugs is a major problem in today's pharmaceutical Industries. The present study used the Tetracycline Hydrochloride Drug in textile processing. The successful dyeing of Jute fiber with this drug by the exhaust process has paved the way for the use of expired or ineffective medication...

The present study was carried out for dyeing cellulosic fabric using bi-functional reactive dye and analysing the dye fixing ability of the reactive dyeing in presence of Tetracycline 250mg. The results were compared with the conventional dyeing methods. It is observed that the dye fixing in presence of pharmaceutical drugs gives better results as compared to conventional dyeing. Tetracycline is a group of broad-spectrum antibiotics whose general usefulness has been reduced with the onset of antibiotic resistance. The tetracycline consists of polycyclic ring with different side chain and a broad spectrum class of antibiotics against aerobes and anaerobes. Tetracycline’s are primarily bacteriostatic and exert their antimicrobial effect by inhibition of protein synthesis. Tetracycline is about 65% bound to plasma protein. The protein binding for intermediate and long lasting analogy i...

The waste cocoon which has potential amino acids and properties which are still unexploited is used in various stages of textile processing and even in the treatment of the major textile waste which is the waste water generated in the processing of textile especially dyeing. The property of the protein to behave as a natural flame retardant is utilized.In the present study the cocoon solution and powder was prepared. This solution was applied on different substrate including both synthetic and natural fabric.From the XRD data of the cocoon shell it is very much clear that the amorphous region is nearly 50% and crystalline it’s nearly about 12% and hence the solubility in the alcohol is easier indicating the presence of ketonic nature being more dominant. From FT-IR results, the major groups present in the cocoon shell are at 1232 cm-1 which reflects amide stretching, 1508cm-1 the nitro stretching and 1618 cm-1 ketone stretching whereas in the cocoon powder has 3388 which is also for amide stretching and 1681 cm-1 for ketone.Thus, this is the first attempt to study the recycling and reusing of cocoon waste in textile processing as an auxiliary as well as a finishing agent. It is interesting to observe that this green technology is very much viable if attempted on commercial scale.

Wounds are defined as self healing process but chronic wounds needs better handling and care from different parameters like moist conditions, application of herbs biocompatibility, and microbial infections. Wound dressing gives excellent wound healing than conventional/ traditional wound dressing. Some of the examples are Hydrogels, hydrocolloid, mapilex foam, etc. Traditional wound dressing is used to treat minor injuries like cuts. Eg: Normal saline and guaze. Several studies have documented the use of plant extracts for development of bioactive wound dressing. This review focuses on bioactive substances, natural and modified polysaccharides, proteins and synthetic materials in wound dressing for wound healing. Ideal wound dressing should achieve the wound healing with less time and cost. Significance of synthetic polymer films, foam dressing, hydrocolloids, hydrogels, and alginate dressing and their properties conforming the wound healing have been reviewed. Plant derived compounds which have anti-inflammatory, anti-microbial, high levels of antioxidants could be benefited for wound healing. Vegetal and bee products such as honey, Propolis and many more used in wound dressing as a bioactive substance is also discussed.
