Factorial optimization of the effects of melt‐spinning conditions on biodegradable as‐spun aliphatic–aromatic copolyester fibers. III. Diameter, tensile properties, and thermal shrinkage

Abstract

ABSTRACT:To model the melt-spinning process of biodegradable as-spun linear aliphatic-aromatic copolyester fibers, a fraction factorial experimental design and appropriate statistical analysis for the 32 screening trials involving five control parameters were used. Because of their central role in the production processes and end use textiles, it is important to simulate the mechanical and thermal shrinkage properties of AAC fibers. Concise statistical models of fiber behavior are based on factorial experimental design data. Process's data are collected, analyzed, and mathematical models created to predict the diameter, tenacity, elongation at break, modulus, and thermal shrinkage of the spun fiber in terms of random variables and their associated probability distributions. The theoretical regression models obtained form the main source code in the enhanced forecasting program, which presents the melt-spinning process of aromatic-aliphatic copolyester fibers. Factorial statistical approaches, based on over indicated region levels of meltspinning process parameters, are given in terms of assumptions and theory to produce biodegradable, environmentally friendly fibers for different applications.

A Review on Melt-Spun Biodegradable Fibers

“…Younes et al conducted several studies [183][184][185][186][187][188][189] on melt-spinning, characterization, and simulation of different properties of aliphatic-aromatic copolyester (AAC) fibers, focusing on PBAT. They used a laboratory melt-spinning plant to produce multifilament yarns (30 or 55 filaments).…”

3-dimensional (3D) fabricated polymer based drug delivery systems

“…This can be achieved by multiple methods, the most common being by melting, often referred to as hot-melt extrusion (HME). This approach has been employed to produce polymer-based rods [52], pellets [53] and fibres [54] loaded with therapeutic substances. Hot -melt extrusion over recent years has found widespread application as a viable drug delivery option in the drug development process and has been successfully applied to enable integration/distribution of poorly soluble drugs [55][56][57][58][59].…”
