Abstract (en)
[origin: EP0052830A2] Ropes, cords, belts and hoses are impregnated with a finishing compsn. consisting of a vinyl-pyridine copolymer latex, an HCHO resin precondensate, HCHO, water and opt. an age-stabiliser and dye. The impregnated articles are dried, pref. 10 min. to several hrs., and heat-treated at 130-180 deg.C, pref. for 1-10 min.. Finishing increases (i) article resistance to abrasion thereby lengthening service-life, and (ii) dimensional stability under side pressure. The ropes,cords, belts and hoses consist esp.of synthetic fibre- or filament yarn. The impregnating mixt. pref. consists of 250-900 pts.wt. 40, aq. vinyl-pyridine copolymer latex, 250-31- pts.wt. water, 50 pts.wt. 40% aq. HCHO resin precondensate and 20 pts.wt. 30 % aq. HCHO. The vinyl-pyridine copolymer latex can contain up to 50% styrene-butadiene rubber latex. The compsn. can contain 20-30% dry solids. Wt. ratio vinyl-pyridine copolymer latex : HCHO resin precondensate can be 5 :1 to 20 : 1, as dry solids. Dry solids deposit quantity is 5-20 wt.% w.r.t. dry unfinished article wt..
