The varieties of using nonwovens (NW) increases. The results of study about the influence of hybrid fibres content and technological parameters of production on properties of NW made from webs of two contents of hemp, recycled polyethylene terephthalate and polypropylene fibres, produced in two temperature and pressure conditions are presented. It is concluded that NW surface parameters and mechanical properties can be purposefully influenced with webs composition and production technology of NW. Produced NW are applicable, where lightweight and water permeable materials are necessary.

Pre Treatment

To create the heat-bonded geotextile with desirable properties, the mix of fibres (hemp, recycled polyethylene terephthalate and polypropylene fibres) for nonwoven webs formation and additional polypropylene reinforcing mesh are used. The results of the study on the influence of the reinforcing mesh on the properties of nonwoven composites (NWCs) are presented. Mechanical properties, water penetration and air permeability of the thermoplastic mesh reinforced NWCs depend on the hemp fibre pre-treatment time, mass per unit area and thickness of the used web and location of the reinforcing mesh. Obtained results allow concluding that mechanical as well as water penetration characteristics of the produced heat-bonded geotextiles are higher, while air permeability is comparable to the properties of the commercial prototype.

The Impact

This work explores a novel blend of recycled polyethylene terephthalate/polyamide 11 (rPET/PA11). The blend of rPET/PA11 was introduced to enhance the mechanical properties of rPET at various ratios. The work’s main advantage was to utilize rPET in thermoplastic form for various applications. Three different ratios, i.e. 10, 20 and 30 wt.% of PA11 blend samples, were prepared using a twin-screw extruder and injection moulding machine. The mechanical properties were examined in terms of tensile, flexural and impact strength. The tensile strength of rPET was improved more than 50%, while the increase in tensile strain was observed 42.5% with the addition of 20 wt.% of PA11. The improved properties of the blend were also confirmed by the flexural strength of the blends. The flexural strength was increased from 27.9 MPa to 48 MPa with the addition of 30 wt.% PA11. The flexural strain of rPET was found to be 1.1%. However, with the addition of 10, 20 and 30 wt.% of PA11, the flexural strain was noticed as 1.7, 2.1, and 3.9% respectively. The impact strength of rPET/PA11 at 20 wt.% PA11 was upsurged from 110.53 to 147.12 J/m. Scanning electron microscopy analysis revealed a dispersed PA11 domain in a continuous rPET matrix morphology of the blends. This work practical implication would lead to utilization of rPET in automobile, packaging, and various industries.

This study produces composite geotextile, and evaluates its effectiveness of being used for soil protection. Kevlar fibers, high strength polyethylene terephthalate (HPET) fibers, recycled polyethylene terephthalate (RPET) fibers, and nylon grids are made into Kevlar/PET/Nylon composite geotextiles, which are then tested for air permeability, and tensile, tearing, and bursting strength. The experimental results show that when the ratio of Kevlar fibers to HPET is 0/40, the resulting composite geotextile has the optimum mechanical properties, where the tensile strength is approximately 990 N, tearing strength is approximately 890 N, bursting strength is approximately 3700, and an air permeability is around 35 cm3/cm2/s.
