A hybrid textile refers tofabric that has more than one type of structural fibre in its manufacture. Itis a mixture of spun yarns of reinforcing fibres and thermoplastic matrixfibres. Normally in a multi layered fabric, if the properties of more than onefibre are needed, two different fabrics will be used. These fabrics had theirown disadvantage of brittleness, lengthy cure cycles, and inability to recycledamaged parts. Hybrid fibres are a positive advancement over such intrinsicproblems in a way that the fabric will have just one layer with one fibrerunning in the weft direction and the second, different fibre running in thewarp direction. It can also be woven as alternate threads of each fibre in eachweft and warp direction.
Hybrid yarns can bemanufactured through many ways like co-wrapping, core spinning, andcommingling. This enables uniform distribution of the reinforcement fibres andreduces its damage. It generally comprises of 50 55 % of reinforcing fibresand 50-45 % of thermoplastic fibres. Using hybrid yarns in textiles enhancesits performance in high end applications. They provide goodmatrix-reinforcement, excellent sealability, and chemical resistance, and aresuitable for the environments adequate abrasion resistance.
Parallel fibres are inserted indifferent orientations layer by layer, and are stitched through a loop systemwith a thin polyester yarn. Thus, a range of fabrics with many differentproperties for the industry of composites is obtained. Manufacturing of hybrid yarndoes not involve environmental problems as the thermoplastic polymers can bereused in a far easier way. Hybrid textiles are manufactured by weaving together;various fibre combinations of carbon, aramid, glass, etc.
- Aramid and Glass: The combination of aramid and glass posses good compression of aramid, and tensile strength of glass along with a lower production cost.
- Carbon and Glass: This combination consolidates the compression strength and stiffness of carbon with less density along with the lesser cost of glass.
- Carbon and Aramid: The high tensile strength of aramid fibres and combined with the tensile strength of carbon. Both the fibres have less density, but are costlier.
Hybrid Yarns with Plant BastFibres: These yarns include natural plant bast fibres in combination with thermoplasticfibres. The fabrics made from this yarn are applicable for low to mediumstrength applications. These fabrics are environmentally friendly and are analternative to fiberglass based composite reinforcements.
Various industrial applicationsof high performance, Hybrid Textiles:
Hybrid fabrics can be used in awide range of industrial applications:
- Aircraft applications
- Industrial applications
- Medical applications
- Construction industry applications
- Aquaculture for waterproof clothing
- Architecture
- Agriculture
- Windproof clothing
- Automotive industry in making sear covers, carpets etc
Hybrid fibres posses bettermechanical properties, reduce delamination and maximize tensile strength. It ispossible to cut this fabric into different widths without the fibres fallingapart while laminating or handling. It further posses excellent drapability.
