“…In this study, cellulose acetate fibers were generated by electrospinning, using equipment developed at the Pedagogical and Technological University of Colombia in the DANUM group, this allowed different types of nanoscale fibers to be obtained, with different substances such as chitosan, starch acetate, cellulose, polylactic acid (PLA), among others; It also allowed finding the optimal processing parameters (concentration, tension, flow out and away from the needle to the collector) that affect the final product quality [21][22] .…”

Cellulose is one of the oldest natural polymers; it is renewable, biodegradable, and can be derivatized to manufacture useful products. The electrospinning, a technique for the manufacture of nanofibers, has garnered attention in recent years due to its versatility and potential for applications in various fields such as biomedicine, tissue engineering and also filtration. In this study, cellulose acetate fibers have been obtained by electrospinning. To achieve these results, the cellulose was initially obtained from the sugarcane bagasse of local plantations in Moniquira, Boyaca, then cellulose was modified to obtain cellulose acetate, which has enhanced properties for electrospinning. Yarn parameters were determined, such as needle-manifold distance, flow rate, voltage and polymer concentration, among others. Instrumental analyses were carried out including Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Differential Scanning Calorimetry (DSC), and Thermogravimetric Analysis (TGA). As a result, cellulose acetate fibers were obtained with an average diameter of 258 nm, with excellent properties such as temperature resistance. This was done in order to continue the work on nanofiber functionalization, as for example, cationization of cellulose and further addition of reactive dyes.

“…However, applications of nanofibers are still limited because of poor tensile properties, and lack of scale to satisfy the growing demand . Others have paid attention to develop new methods and equipment . A plethora of literature is available on the theoretical analysis of jet formation in electrospinning process .…”

An optimization study was conducted to understand the influence of thickness, speed of testing, and gauge length (specimen test length) on important mechanical properties of poly(vinyl alcohol) nanofiber webs. Using orthogonal experimental design, experimental trials were optimized for the three testing parameters, which enabled to undertake 25 experiments involving the three variables at five different levels. Polynomial regression equations show that the three variables have interactive influence on the mechanical properties tested. Of the three variables, thickness of nanofiber webs seems to have maximum influence on tensile properties. This study showed that the optimal values for tensile testing of nanowebs are gauge length at 0.50 cm, thickness of nanowebs at 0.10 mm, and speed of testing at 25 mmÁmin −1 . This study will provide an opportunity to establish a standard method for the tensile evaluation of nanowebs involving gauge length, thickness, and speed of testing.
