TH10854B - Processes and equipment for the production of thread or synthetic fibers from polymers. In particular, polyamide, polyester or polypropylene. - Google Patents

Abstract

The fabrication is a process for the manufacture of plastics that have been completely removed from polymers by fusing on micro fibers that have been cooled at least to the hardening temperature. This is followed by a small stringer, and then, for the purpose of stretching, it is heated to a temperature higher than the hardening point, and at the same time the pan is blown with air to provide tension when stretched as needed. This micro-fiber has a unique denfier value <1.0 dtex in a straight line that is not tied through the heating zone and is carried out by air in the opposite flow. Thus, a perfectly arranged and synthetically formed micro line was obtained with a high tensile relative speed and low heating area. This synthetic thread has low relative elongation and is immediately usable. Due to the fineness of this thread, it is possible to produce a very fine and flexible silk-like fabric without any post-processing.
