“…Thermal drawing of poly(AN–IA) copolymer fibers after plasticization drawing has also been suggested as a way to obtain high‐strength fibers. The plasticization drawing (λ) was varied from 3.0 to 7.0 38. The samples were subsequently thermally drawn in an air tube 0.75 m long to the maximum possible ratio with a step of Δλ therm = 1.3.…”

Acrylic fibers are among the most useful synthetic fibers for textile applications, and special acrylic fiber (SAF) has industrial applications. The physical and mechanical properties of fiber are affected by several parameters; one such parameter is coagulation conditions: bath temperature, bath composition, and drawing. Acrylonitrilecarboxylic acid copolymers, that is, acrylic methacrylic and itaconic acid, were converted into fibers using the dry-jet wet spinning technique. The coagulation bath temperature was varied from 5°C to 35°C, and the properties of the fibers so obtained were investigated. The effect of the final drawing ratios (6.5 and 8.5) on such physical and mechanical properties as tenacity, sonic modulus, initial modulus, density, crystallinity index, and X-ray orientation were also investigated. In addition, thermogravimetric analysis and scanning electron microscopy were used to determine the thermomechanical properties and fracture morphology of the fibers.
