Mordant red 19 is a typical mordant dye. Like many mordant dyes, it features the azo group (RN=NR) and various sites for chelating to metal cations. A French Indienne, a printed or painted textile in the manner of Indian productions, which used mordants to fix the dyes
In biology, determination is the process of matching a specimen or sample of an organism to a known taxon, for example identifying a plant as belonging to a particular species. Expert taxonomists may perform this task, but structures created by taxonomists are sometimes used by non-specialists.
Nonwoven fabric or non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres (continuous long), bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt , which are neither woven nor knitted . [ 1 ]
Hydrophilicity, roughness and surface charge determine the interaction of cellulose fibers with an aqueous environment. Already in 1950, the charge at the interface between cotton as the predominant cellulose fiber and an aqueous surrounding was investigated by the streaming potential method to assess the surface zeta potential.

Mechanical processing is a recycling method in which textile fabric is broken down while the fibers are still preserved. [5] Once shredded down, these fibers can be spun to create new fabrics. [ 5 ] This is the most commonly used technique to recycle textiles and is a process that is particularly well developed for cotton textiles. [ 5 ]
DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections (also called "sequences"), an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of the UPC barcode ...
Other than fiber structure, it is chemical orientation and different finishing methods such as singeing, heat-setting, calendering, silk surfacing, mercerizing, and bio polishing, etc. [1] [7] Cotton when mercerized has a round cross-section that appears brighter than untreated cotton (with a bean cut view.) [ 1 ] : 56 [ 8 ]
A Southern blot is a method routinely used in molecular biology for detection of a specific DNA sequence in DNA samples. Southern blotting combines transfer of electrophoresis-separated DNA fragments to a filter membrane and subsequent fragment detection by probe hybridization. [1]
