Doubling (textiles)

When people talk about "doubling" in textiles, they usually mean taking one piece of yarn or thread and twisting it together with another piece to create a thicker, stronger strand. It's kind of like braiding hair, but instead of three sections, you only have two.

To do this, you need a machine called a "doubler." This machine takes two strands of yarn or thread and twists them together in the opposite direction of the individual strands. This twisting action causes the two strands to become intertwined and creates a new, stronger strand that is double the weight and thickness of the original individual strands.

Once the two strands have been twisted together, they can be wound onto a spool or cone and used as a single, stronger strand of yarn or thread. This is often done when making heavy-duty fabrics or ropes that need to be able to withstand a lot of wear and tear.

Overall, doubling in textiles is all about making things stronger and more durable by combining individual strands of yarn or thread to create a thicker and more robust strand.
