Fibres left after carding and combing:
After the carding and combing process of spun fibers, the short fibers that are left behind are known as "waste" or "noils."

Explanation:
- These short fibers are a byproduct of the spinning process and are typically too short to be used in the final yarn.
- The carding and combing processes are essential steps in preparing fibers for spinning by aligning the fibers and removing any impurities or short fibers.
- The waste fibers can still be repurposed for various applications such as insulation, padding, or even recycled into new fibers.
- Noils can also be used in nonwoven textiles or blended with other fibers to create unique yarns with different textures and characteristics.
Overall, while these waste fibers may not be suitable for traditional yarn production, they can still have value and be utilized in different ways within the textile industry.
