Polyester is the most widely used synthetic fiber globally. However, recycled products from waste polyester textiles (WPET) often suffer from poor performance and low value. This paper introduces solid‐state shear milling technology (S3M) to transform WPET into ultrafine fiber powder with a high aspect ratio, followed by solid‐state drawing processing producing to produce high performance HDPE/WPET composites. Compared with the pure high density, the flexural strength of WPET with 15% content increased to 24.94 MPa, while the tensile modulus and flexural modulus increased to 507 and 798 MPa, respectively, and the prestretched sheet with good performance was prepared. At a solid‐state drawing ratio of 6, the composite exhibited an impressive tensile strength of 116.8 MPa, representing a 600% increase compared to unstretched samples. Additionally, the in‐plane thermal conductivity reached 2.89 W/mK, which was 438% higher than unstretched samples. SAXS and 2D‐WAXD analyses demonstrated that high solid‐state drawing enhanced the orientation of WPET fibers and HDPE, forming an oriented structure. This led to composite crystallinity and orientation levels of 63.7% and 93%, respectively. This study has represented a novel approach to producing high‐performance functional products from dye‐containing polyester fabrics without requiring separation or physical recovery processes.

This study investigates the mechanical properties of nonwoven hybrid composites made from recycled cotton/polyethylene terephthalate (PET) with various fiber weight percentages (100/0, 0/100, 75/25, 60/40, 50/70, 60/40, and 25/75). The multilayered nonwoven carded webs are manufactured by the carding machine, while the manual lay‐up technique is used to fabricate nonwoven‐reinforced composites. Their tensile, flexural, and impact properties and microstructure are then examined. It is found that the tensile modulus and strength increase with the increase in cotton, while the impact strength improves with the increase in PET. The composite of 75% cotton/25% PET offers 92.13% and 67.87% higher tensile modulus and strength than the composite of 25% cotton/75% PET; however, the composite of 25% cotton/75% PET shows 83.09% and 36.22% higher flexural modulus and strength, and 187% more impact strength, respectively, than the composite of 75% cotton/25% PET. The outcome of this study indicates that nonwoven composites with higher contents of recycled cotton can potentially be applied in building and construction sectors where substantial tensile strength is necessary, while composites with comparatively higher contents of recycled PET may be used for various potential applications (e.g., helmets, surfboards, and automotive interiors) where significant flexural and impact strengths are required.

Sustainable hybrid composites, made of two different natural plant fiber types, are increasingly being attracted by composite researchers, for their cost effectiveness and ability to control mechanical performances through varying weight ratios of different fibers. In contrast, their lower mechanical properties are reported in the literature, because of strength variations of different fiber types and an improper fiber‐matrix stress distribution. Therefore, it is aimed to develop sustainable hybrid composites from two dry fiber preforms—woven fabric and short fiber preform—originated from same fiber type (jute). A highly packed short fiber preform is used as the core layer, while woven fabrics (plain/twill–rib/twill–diamond) are used in the skin layers for producing sandwiched hybrid jute composites. Mechanical tests and scanning electron microscopy images show that hybridized plain fabric/short fiber preform composites have better mechanical properties (≈58 MPa tensile strength/≈117 MPa flexural strength/≈112.12 kJm−2 impact strength with an ≈487.4% improvement) compared to other fabric structures hybrid/nonhybrid composites. This enhancement is related to the interlocking of short fibers with long plain fabric leading to a strong fiber‐matrix interfacial bonding. Thus, this developed hybrid composites, can be applied in many semi‐structural applications, wherein composites’ low cost and mechanical performances are primary concerns.
