Title: Random laid needle felts with high tear strengths - produced by treatment with finishing agent before needling
Inventor: BLAUHUT WILFRIED DIPL ING
IPC: D04H3/14
Filed: 1980-03-10
Abstract: Random-laid needle-felts are impregnated before needling with 0.5-0.8 wt.% of a finishing agent which is applied as a mist from an atomizer, which is sucked through the freshly-laid web immediately after its formation and before any consolidation occurs. The web is formed on the outside of a suction drum having two separated suction zones. Above the first zone is the distributor head which spreads the fibres which form the web, and above the second zone, which follows immediately upon the first, is the atomizer which sprays the finishing agent. The finishing agent improves the efficiency of the needling operation and reduces fibre damage. This gives considerable increases in the strip tear-strength of the needled fabric, e.g. from 550N to 1070N for a 400g/sq.cm web of filaments with a tenacity of 3.2g/dtex, and a needling-density of 400/sq.m.
