Abstract RU 2407839 C2

FIELD: textile, paper.

SUBSTANCE: fabric for paper-making machine comprises system of threads arranged along with fabric feed in machine, and system of threads arranged across fabric feed in machine, besides, threads in system of threads arranged along with fabric feed in machine are woven with threads in system of threads arranged across fabric feed in machine, to form specified fabric, and threads arranged along with fabric feed in machine are used as connecting threads to connect layers of specified fabric. Besides, system of threads arranged across fabric feed in machine, comprises multiple threads made of material that prevents curling of edges, when fabric of paper-making machine is loaded. At the same time specified multiple threads arranged across fabric feed in machine comprises threads made of mixture of polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) in amount of 60-90 wt % and 10-40 wt % accordingly.
