In this work, the spinning abilities of polyoxymethylene-based core–sheath bicomponent fibers were investigated. Bicomponent fibers were prepared using polyoxymethylene as the core material and poly(lactic acid) blended with polyoxymethylene or pure polyoxymethylene as sheath materials, and their characteristics were investigated and compared. Fiber properties such as elongation are important because they directly relate to the spinning performance during fiber processing. This work reports the impact of the composition designation of the core–sheath bicomponent fibers on the controllable stability of poly(lactic acid) in polyoxymethylene–poly(lactic acid) blends in the fibers, as well as the influence of the core–sheath material on the structure, fiber diameter and distribution, thermal stability, and mechanical properties of the core–sheath bicomponent fibers. It was found that the selection of core and sheath materials affected the structural characteristics of the fibers. The polyoxymethylene core–polyoxymethylene sheath (FV) fiber showed dimensional stability. However, the polyoxymethylene core–poly(lactic acid)/polyoxymethylene sheath (FT30) fiber provided the optimum limit of poly(lactic acid) content for controlling the stable properties of the core–sheath bicomponent fibers.

Multifilament Yarns

Multifilament yarns of polyoxymethylene (POM) and poly(lactic acid) (PLA) blends were prepared using a melt-spinning method. The ratios of the POM/PLA fibers studied were 10/90, 30/70, 50/50, 70/30, and 10/90 by weight compared with that of the pure polymers. The extrusion of the dry blend polymers was carried out using a single-screw extruder at 180–210℃ with a winding speed of 800 m/min. The thermal and morphological analysis of the multifilament yarn confirmed the phase separation of the two polymers. However, the mechanical properties of the blends showed excellent elongation at break, which confirmed the good distribution of PLA in the POM matrix. POM/PLA with weight ratios of 70/30 and 90/10 showed high tenacity. The elongation of the POM/PLA blends shows excellent results, which is unusual for polymer blends with phase separation.

The Impact

Poly (lactic acid)/poly (butylene succinate) (PLA/PBS) blend fibers with high miscibility and improved elongation with comparable mechanical strength were fabricated using the melt spinning process in order to reduce the impact on the environment by long-lasting plastics-based composites. The PLA/PBS blend fibers produced in different ratios have revealed high miscibility, which has been confirmed by morphological studies. The thermal properties showed the melting temperature of PLA at 167.13℃ and PLA/PBS blends at 169.18℃, and an increased content of PBS in blends also led to improved crystallinity. Importantly, during tensile testing, it is observed that the fracture behavior of the specimen changed from brittle fracture of neat PLA to ductile fracture of the blends, as demonstrated by the significant increase in the elongation at break with comparable tensile strength and modulus. Furthermore, the washing fastness, rubbing fastness, exhaustion values, strength loss, and shade depth ( K/ S value) for the knitted and dyed fibers were explored. It was found that the exhaustion and K/ S value increased when the temperature increased, but the strength decreased. The exhaustion and K/ S value of PLA/PBS blend fabrics improved compared to pure PLA fabric, with excellent washing and rubbing fastness.
