Abstract

Inventia se refera la un procedeu de obtinere a placilor termopresate, din deseuri de tesaturi, dublate cu folii de polietietilena, rezultate în procesul de croire a insertiilor. Procedeul de realizare a placilor termopresate este caracterizat prin aceea ca , în scopul realizarii deseurilor textile, într-o prima faza, deseurile textile dublate cu folii cu polietilena pentru îmbracaminte sunt taiate pe o masina de taiat fire, pana ce rezulta bucatele cu cu suprafata maxima de 4 cm la puterea 2 se introduc într-o matrita avînd în amestec substante ignifuge, în faza urmatoare se face o presare propriu+zisa precedenta de reîncalzire timp de cedenta de reîncalzire timp de 15....20 min, presiunea fiind pe minut de 170 kgf/cm la puterea 2 durata min ima fiind de 4 min.The invention relates to a process for the production of heat-treated sheets, from fabric waste, doubled with polyethylene sheets, resulting in the insertion process. The process for making the heat-shrinkable plates is characterized in that, in order to achieve the textile waste, in a first phase, textile waste doubled with polyethylene foil for clothing is cut on a yarn cutting machine until the pieces with a maximum surface 4 cm at power 2 are introduced into a matrix having flame retardants in the next step, a proper pressing is performed prior to reheating during the reheat assignment for 15 ... 20 min, the pressure being per minute of 170 kgf / cm at power 2 min duration of 4 min.
