摘要 |
<p>Production of a shapable tufted product (I) involves laying a melt-blown non-woven (II) on a shapable polyester pile support (III) and tufting (II) and (III) together. Independent claims are included for shapable tufted products obtained by the process, which: (A) at room temperature have maximum tensile stresses in the longitudinal and transverse directions (EN 29073-3) of 250-400 (preferably 275-375) N/5 cm and 180-300 (preferably 203-250) N/5 cm respectively and maximum tensile extensions in the longitudinal and transverse directions (EN 29073-3) of 45-60% and 42-45% respectively; (B) at 140[deg] C have maximum tensile stresses in the longitudinal and transverse directions (EN 29073-3) of 185-200 N/5 cm and 85-120 N/5 cm respectively and maximum tensile extensions in both the longitudinal and transverse directions (EN 29073-3) of 65-70%; and/or (C) at room temperature show a tear propagation resistance (DIN 53859-3) of 170-240 N.</p> |
