“…After hot pressing, the CLN group tends to be softer and exhibits a bursting strength of 736.96 ± 8.60 N. Finally, the NLN group exhibits the lowest bursting strength of 420.65 ± 5.94 N, which is ascribed to the top and bottom layers being nylon spacer fabrics. Nylon spacer fabrics are formed of interconnected loops, and they appear to be sleek, which then compromises the bursting strength of the NLN group [ 38 , 39 , 40 , 41 ].…”

In this study, a low-melting-point polyester nonwoven fabric (L), a nylon spacer fabric (N), and a carbon fiber woven fabric (C) are laminated in different orders and then needle-bonded at a depth of 15.0 cm to form NLC, NLN, CLC, and CLN composites with a sandwich construction. Regardless of the lamination order, four composite types exhibit high tensile strengths and tearing strengths. Based on the ASTM D4935-18 test standard, the electromagnetic wave shielding measurement is conducted in a frequency range of 1~3 GHz. The two groups—NLC and CLN—demonstrate different electromagnetic wave shields, which are −45~−65 dB for the former, and −60 dB for the latter. According to FTTS-FA-003, in the specified requirements of the test method for electromagnetic shielding textiles, the proposed composites achieve level III, which is the highest standard, and are thus qualified for use in the aviation, construction, and commerce fields.

“…Certain fibres, such as high-tenacity fibres or fibres with good interlocking properties, can enhance tear resistance when blended appropriately. The fibre blend composition impacts burst strength by influencing the fabric's structural integrity and resistance to internal pressure [5,18,19]. Blending fibres with high tensile strength and good cohesion can improve the burst strength of needle-punched nonwovens.…”

This research investigated the innovative synthesis achieved through blending five distinct fibres (Polyacrylonitrile (PAN), Polyester (PET), Polylactic acid (PLA), Polypropylene (PP), and Polyphenylene sulfide (PPS)) in the production of needle-punched nonwoven fabrics tailored for air filtration applications. The study investigated the effects of needle-punched nonwovens made with up to five fibres on the physical and mechanical properties, addressing a gap in existing literature. The method involved manual and machine opening, blending, and carding of fibre s, followed by producing three samples with different web arrangements (cross laid web, parallel laid web, and pre needled parallel lad web). The study employed standard test methods to characterize physical and mechanical properties. Results indicated that web arrangement and pre-needling significantly influenced various properties, with cross and parallel-laid web arrangements having minimal impact on thickness and bursting stretch. The parallel arrangement, whether pre-needled or not, showed no significant effect on GSM, fabric density, bursting strength, tear strength, abrasion resistance, and filtration efficiency. The highest abrasion resistance, lower pressure drop, highest fabric stiffness, moderate tensile strength, and higher bursting strength were observed in a cross-web arrangement. This study contributed valuable insights into the intricate interplay of fibre composition, web arrangement, and pre-needling in the design of advanced needle-punched nonwoven fabrics for air filtration. The findings provided a nuanced understanding of how these factors collectively impact the mechanical and physical characteristics of the material, paving the way for enhanced efficiency, durability, and versatility in air filtration applications.
