“…Since chitosan NH 2 and OH groups can form co-ordination bond with metal ions [15], by increasing pH of the solution to pH = 10 dropwise addition of NaOH, the stable complex of chitosan/ZnO nanoparticles is formed. (Figure 3, curves a and b) depicts the FTIR of chitosan and chitosan/ZnO nanaoparticles.…”

Synthesis of chitosan/ZnO nanoparticles was performed using different concentrations of ZnO at different temperatures. Nanoparticles of ZnO/chitosan were prepared in rod form with average length 60 nm and average width 5-15 nm. Thus, obtained nanoparticles of ZnO/chitosan were characterized using UV spectrophotometer, FTIR, TEM, X-ray, and SEM. Size and shape of chitosan/ZnO nanoparticles relied on conditions of their synthesis. Notably, chitosan/ZnO in rod form with average length of 60 nm and average width 5-15 nm could be achieved. Application of chitosan/ZnO nanoparticles to cotton fabric conferred on the latter antibacterial and UV protection properties. Cotton fabric was characterized using SEM, ultraviolet protection factor (UPF) rating, and antibacterial (gram-positive and gram-negative) characteristics. Finished cotton fabric exhibited good antibacterial properties against gram-positive and gram-negative bacteria. The UV testes indicated a significant improvement in UV protection of finished cotton fabric which is increasing by increasing the concentration of nanoparticles of ZnO/chitosan.

“…Recently, chitosan-metal complexes have attracted great interests for their potential use in agriculture, medical industry, and food industry (Nieto et al 1992;Shigemasa & Minami 1996;Wang et al 2004;Mekahlia & Bouzid 2009;Higazy et al 2010). It is well known that both chitosan and metals such as Ag, Cu, Ni, Hg, and Zn have the properties of disinfection and bactericide (Wang et al 2005).…”

Badawy M.E.I., El-Aswad A.F. (2012): Insecticidal activity of chitosans of different molecular weights and chitosan-metal complexes against cotton leafworm Spodoptera littoralis and oleander aphid Aphis nerii. Plant Protect. Sci., 48: 131-141.As an alternative to synthetic pesticides, chitosan has received much attention as a biopolymer active against some agricultural pests. The, insecticidal activity of chitosans of four molecular weights (2.27 × 10 5 , 3.60 × 10 5 , 5.97 × 10 5 , and 9.47 × 10 5 g/mol) was investigated against two species of arthropod pests: oleander aphidAphis nerii and cotton leafworm Spodoptera littoralis. In addition, the most active chitosan of 2.27 × 10 5 g/mol was chemically modified with metals of Ag(I), Cu(II), Ni(II), and Hg(II) to give corresponding chitosan-metal complexes. Larval mortality, growth inhibition, and antifeedant activities for third instar larvae of S. littoralis were evaluated at 4 g (a.i.) chitosan/kg diet. Chitosan of 2.27 × 10 5 g/mol and its complexes with Ni and Hg were the most active compounds. The results against A. nerii indicated that chitosans of 3.60 × 10 5 and 5.97 × 10 5 g/mol showed high activity among the different molecular weights in leaf-dip bioassay after 24 h of treatment with 48 and 49% mortalities, respectively, at 1000 mg/l. All compounds had a systemic effect against A. nerii. Chitosans of 2.27 × 10 5 , 3.60 × 10 5 , and 5.97 × 10 5 g/mol showed the highest efficacy at all concentrations tested; however, chitosan-Cu was significantly the most active among the complexes.

“…The -NH 3 + sites of chitosan react with the outer membrane of bacteria, i.e., anionic components, which would prevent the bacteria cell metabolism and inhibit its growth. In chitosan-metal complex, the positive charge in amino group of chitosan is strengthened by the metal cation and that quicken the interaction with anionic components of microorganism cells, therefore, it exhibits higher antimicrobial activity than chitosan-treated jute fabric (Higazy et al 2010b). …”

Over the years, technologies had used for development of various textile products to meet the consumer demands in different fields as per their end-use specifications. The market sustainability of the each new product mainly depends on the raw material as well as functionality. A functional finishing decides the end-use of the products as well as enhances the life of the products. Jute is one of the important natural cellulosic fibers and mainly used for sacking and packaging, rather than it has many advantageous properties. Similar to cotton, jute fiber has the potential to impart different functionality by different chemical finishing for its diversification. This paper reviews the functional finishing on jute textiles with special reference to softening, crease resistant, fire retardant, and hygiene for the satisfaction of the consumer's demand are reviewed.
