T HE TEXTILE industry is seeking innovative manufacturing technology to increase the quality of the fabric, and society needs modern environmental finishing techniques, such as using plasma Treatment as atmospheric-pressure dielectric barrier discharge (APDBD) corona discharge at atmospheric pressure (CDAP) which are gaining popularity in the textile industry due to their many advantages over traditional wet processing methods the textiles industry is gaining in popularity. The initiation of plasma by air or conventional industrial gases, such as hydrogen H2, N2 and oxygen O2 at ambient pressures, may be accomplished. Plasm introduces usable surface groups to provide properties such as antibacterial, UV, flame retardant and antistatic that are used in various fabrics such as cotton, linen, polyester, and surface fabrics after plasma therapy.

N OWADAYS, there is a great interest in the textile industry for the production of functional textiles using environmentally friendly materials and processes. Cyclodextrins are cyclic oligosaccharides obtained by enzymatic degradation of starch truncated cone shape having a hydrophilic surface containing hydroxyl groups and a cavity with hydrophobic character which can form reversible inclusion complexes with various compounds. Several derivatives of β cyclodextrin have been synthesized to enable it to attach to textile fibers permanently. Also, different methods have been developed for grafting of native and modified β cyclodextrin on textile fibers. In this review the methods of application of β cyclodextrin on different textile substrates for obtaining various functional properties including printability, dyeability, and in finishing application as antibacterial, ultraviolet protection wastewater pollutant removal, and fragrance release properties.

The causal organism of brown rot disease Ralstonia solanacearum is a common and dangerous pathogen affecting several economically important crop species. R. solanacearum has a wide range of occurrence and severity in potatoes and other nightshades such as eggplant, tomatoes and green peppers. The main goal of this study is to detect the genetic variation between 14 isolates of R. solanacearum from diverse geographic ecoregions of Egypt using the Start Codon Targeted Technique (SCoT). Ten SCoT primers were used to amplify SCoT markers, taking into account genetic diversity and phylogenetic distance between target isolates. The results showed 143 bands in a range of 130 to 2100 bp, of which 112 bands (76.40%) were polymorphic and 31 bands (23.60%) were monomorphic. Nei's genetic distance and UPGMA method divided the dendrogram of the fourteen isolates into two major groups. Isolates 1, 11, 12, 13 and 14 were grouped together in Group I, while Group II was divided into two main subgroups, in which isolates 5 and 6 were grouped in Subgroup I and isolates 2 and 3 in Subgroup II became. The third group was divided into three subgroups, with the first subgroup including Isolate 4 and Isolate 7. The second subgroup contained isolate 8 and isolate 9. Interestingly, isolate 10 was only grouped in the third subgroup and showed a diversity profile of unique and less related. to other isolates. Regarding disease diversity, this isolate may have different characteristics that will be considered in the future.
