Abstract (en)

The subject-matter of the invention is a method of 100% recycled PET technical fabric production, characterized in that it comprises steps where a warp of yarn obtained from 100% recycled PET filaments is warped with a thickness ranging from 40 to 334, preferably 84 to 334 dtex, and more preferably 84 to 167 dtex; the warp is tied on the loom, preferably using an automatic warp-tying machine; a weft of yarn obtained from 100% recycled PET filaments with a thickness ranging from 58 to 668 dtex, preferably 78 to 501 dtex, and preferably 167 to 334 dtex is threaded on a loom; after loom activation, the fabric pattern is established and weaving is carried out; the finished fabric is wound on a roller; initial quality control and preparation for the washing and dyeing process are carried out; the fabric is washed with heated water at 70°C to 100°C and a pressure of 0-1 bar and dyed at 110°C to 140°C and a pressure of 2.5-3 bar; the washed fabric is subjected to thermal stabilization in order to maintain its physicochemical parameters, and drying; the dried fabric is rolled on rollers and subjected to a final quality control, then the fabric is cut into smaller batches and labeled; wherein the stabilization of the fabric is carried out by annealing the fabric strip at 160°C to 220°C, with a fabric web feed rate from 10 m/min to 30 m/min. The subject-matter of the invention is also a fabric produced by this method.
