Definitions

• the invention relates to a method for equipping ropes, cords, belts, hoses and the like, preferably made of synthetic fiber or filament yarns. Because of the equipment according to the invention, the abrasion behavior is significantly improved and better dimensional stability is achieved.
• Laid, twisted and braided ropes and cords, as well as woven and braided straps made of synthetic fiber and filament yarns are primarily characterized by high linear tensile strength, but their abrasion resistance is not always sufficient.
• Cordage, especially with large rope cross sections, is often not sufficiently stable; the cross-section deforms even with slight lateral pressure.
• Polyamide, polyethylene, polypropylene or polyester filament yarns, preferably polyamide filament yarns, are generally used as materials for the ropes, cords, belts, hoses, etc.
• Suitable polyamides are e.g. Polyamide-6, polyamide-6,6 and aromatic polyamides made from metaphenylene diamine and isophthalic acid or paraphenylene diamine and terephthalic acid.
• the object of the invention was to find a finishing process for ropes, cords, belts etc., in particular made of synthetic filament yarns, in order to reduce, in particular, external signs of wear and tear and to stabilize the shape against lateral pressure.
• ropes, cords, belts and hoses which normally show signs of wear when subjected to heavy mechanical stress, for example due to abrasion and rubbing from the outside, do not wear out as quickly and are dimensionally stable if they are impregnated with equipment, which consists of a mixture of vinylpyridine copolymer latex, a formaldehyde resin precondensate, formaldehyde, water and optionally anti-aging agent and dye, dries and finally subjected to a heat treatment at 130 to 180 ° C.
• equipment which consists of a mixture of vinylpyridine copolymer latex, a formaldehyde resin precondensate, formaldehyde, water and optionally anti-aging agent and dye, dries and finally subjected to a heat treatment at 130 to 180 ° C.
• the finishing compound is applied by dipping, splashing or spraying. It penetrates the ropes, cords, belts, etc. and there, after the condensation, causes each filament or each individual fiber to remain in the position and shape once it has been assumed, and is thus protected from abrasion.
• the ropes, cords, straps, hoses, etc. to be equipped can be unfixed or fixed.
• Formaldehyde resin precondensates are understood to mean, for example, soluble precondensates made from ureas, melamines and phenols with formaldehyde; a precondensed resorcinol-formaldehyde resin is preferably used.
• Butadiene and styrene are particularly suitable as comonomers of the vinylpyridine copolymer latex.
• the latex / resin mixture can be adjusted so that there are no disadvantageous hardenings.
• the required dry substance application should be between 5 and 20% by weight, preferably 12 to 15% by weight, based on the weight of the dry, non-equipped rope, cord, belt or hose material.
• the penetration of the equipment into the filament yarns and the dry substance application quantities can be adjusted by regulating the dry content of the impregnation liquor to the raw materials that are not always prepared uniformly. Unwanted handle hardening, which can occur with increased dryness, is countered by the fact that the increase is made only in the latex portion with the same amount of resin. This measure leads to a high level of processing reliability due to sufficient pot lives.
• the dry content of the mixture is about 20-30%.
• the weight ratio of vinylpyridine copolymer latex to formaldehyde resin precondensate is accordingly 5: 1 to 20: 1 (dry substance).
• mixture components (a) and (b) are premixed separately and then (b) slowly stirred into (a).
• the vinylpyridine copolymer latex may contain other components, for example up to 50% styrene-butadiene rubber latex (SBR latex).
• the lifespan of the round belt treated in this way is several times that of the same non-equipped braided belt.
