METHOD FOR HYDRAULIC SPLICING OF UNBOUNDED NONWOVEN POLYOLEFIN FABRIC AND NONWOVEN HYDRAULICALLY SPLICED POLYOLEFIN FABRIC Russian patent published in 1995 - IPC

FIELD: textile industry. SUBSTANCE: threads are placed on screen with meshes sizing 0,24-0.1 nm and passed under water jets of high pressure of 140,5 kg/cm² and providing total impact energy of not less than 0.7 MJ-N/kg to splice threads. Hydraulically spliced fabric is passed under finer water jets for final treatment at pressure of 21,09-84,4 kg/cm² to redistribute threads. If required, final treatment may be used for hydraulically spliced fabric. Fabric produced by hydraulic splicing possesses higher visual homogeneity, nontransparency, softness, convenience, strength and barrier properties as compared with known fabrics, that render them very useful in manufacture of modern overalls. EFFECT: higher efficiency. 12 cl, 9 dwg, 11 tbl
