ConclusionConclusion

• Hybrid yarns are one of the most promising Hybrid yarns are one of the most promising technologies to solve the main problem in the technologies to solve the main problem in the production of thermoplastic composites being the production of thermoplastic composites being the high viscosity. To achieve this these high viscosity. To achieve this these characteristics various hybrid yarn types have characteristics various hybrid yarn types have been developed such as side by side friction been developed such as side by side friction spinning, co-warping, yarn twisting and spinning, co-warping, yarn twisting and commingling.commingling.
