raschel machines. Stitch-bonding Stitch-bonding is a special form of warp knitting and is commonly used for the production of composite materials and technical textiles. Stitch-bonding machines are used for the sewing processing of nonwoven fabric, to increase its fastness and toughness. The Stitch-bonding warp knitting machine or Non-woven warp knitting machine is for producing technical textiles such as shoe interlining, shopping bag, geotextile dewatering bags, reinforced composite glass fiber textile and other fabrics*[https://www.azentex.com/Stitch-bonding-machines.html]. As a method of production, stitch-bonding is efficient, and is one of the most modern ways to create reinforced textiles and composite materials for industrial use. The advantages of the stitch-bonding process include its high productivity rate and the scope it offers for functional design of textiles, such as fiber-reinforced plastics. Stitch-bonding involves layers of threads and fabric being joined together with a knitting thread, which creates a layered structure called a multi-ply. This is created through a warp-knitting thread system, which is fixed on the reverse side of the fabric with a sinker loop, and a weft thread layer. A needle with the warp thread passes through the material, which requires the warp and knitting threads to be moving both parallel and perpendicular to the vertical/warp direction of the stitch-bonding machine. Stitch-bonded fabrics are currently being used in such fields as wind energy generation and aviation. Research is currently being conducted into the usage and benefits of stitch-bonded fabrics as a way to reinforce concrete. Fabrics produced with this process offer the potential of using "sensitive fiber materials such as glass and carbon with only little damage, non-crimp fiber orientation and variable distance between threads". In the extended stitch-bonding process (or the extended warp-knitting process), the compound needle that pierces the piles is shifted laterally according to the yarn guides. This then makes it possible for the layers of the stitch-bonded fabric to be arranged freely and be made symmetrical in one working step. This process is advantageous to the characteristics of the composite as the "residual stresses resulting from asymmetric alignment of the layers are avoided, [while] the tensile strength and the impact strength of the composite are improved." Needle shift Needle shift technique is when both outer warp layers are secured in one procedure by incorporating a shift of the needle bar during stitching, creating endless possibilities for the arrangement and patterns in stitch-bonding.
