What is TPU piping cord

There is a definition of piping cord: “Piping cord is a thin, round cotton “rope” made especially for sewing. It comes in a variety of thicknesses, depending on how full you want your finished piping to be. To make piping, you take a bias strip and fold it over the piping cord. To attach it to your article you sew the open end into the seam.”

TPU piping cord is the piping cord made of TPU material. TPU is an eco-friendly plastic material, which has no harm to human or environment. Cotton piping cord can be used for clothes and canvas bags. However, some waterproof bags, saddle and other outdoor products usually use leather or plastic piping cord. Leather piping cord is a good choice, but it is easy to get worn. Then plastic piping cord such as PVC or TPU one become popular. Both PVC piping cord and TPU piping cord is waterproof, but PVC one is not eco-friendly. Some cheap PVC cord even be smelly. If you need to shape a high quality waterproof or fashion bag, you can try TPU piping cord.
