  • Linear formations which are not processabie by standard textile technologies also include some hollow fibers or hoses by which using these technologies would cause their deformation, especially undesired deformation, of their inner space, which might even be completely closed, whereby these fibers/linear formations would lose their advantageous characteristics, such as the ability to transport a liquid, etc.
