“…This may be due to the fact of thread with two filaments presenting greater porosity and pore size, due to the greater torsion angle (see Table 2 ), which caused the thread to become weak. Torsion of the CS filaments contributes to formed pores in the structure of threads, leading to uneven load distribution through the thread cross-section, causing a reduction in tensile strength [ 28 , 29 ]. This effect was also observed in our study previously reported [ 23 ].…”

This study aimed to develop meshes from the weaving of mono- and multifilament wet-spun chitosan (CS), for possible biomedical applications. In the wet-spinning process, CS solution (4% w/v) was extruded in a coagulation bath containing 70% sodium hydroxide solution (0.5 M), and 30% methanol was used. The multifilament thread was prepared by twisted of two and three monofilaments. CS threads obtained were characterized by tensile tests and scanning electron microscopy (SEM). Moreover, it was verified from the morphological tests that threads preserve the characteristics of the individual filaments and present typical “skin-core” microstructure obtained by wet spinning. CS woven meshes obtained were evaluated by optical microscopy (OM), tensile test, swelling degree, and in vitro enzymatic biodegradation. Mechanical properties, biodegradation rate, and amount of fluid absorbed of CS woven meshes were influenced by thread configuration. Hydrated CS meshes showed a larger elastic zone than the dry state. Therefore, CS woven meshes were obtained with modular properties from thread configuration used in weaving, suggesting potential applications in the biomedical field, like dressings, controlled drug delivery systems, or mechanical support.

“…The paste is prepared with different ingredients like preservatives, adhesive, softeners, base materials, etc. The improvement in strength and abrasive resistance is necessary for the yarn so that it can with stand the stresses and strains exerted during the weaving process [8][9][10][11].…”
