Abstract
The invention describes food-compatible monofilaments and flat-shaped bodies made from them, wherein the monofilaments are based on polyester with the addition of 0.5 to 3.5 percent by weight of a polycarbonate, and which are characterized by an especially high abrasion resistance and resistance to foods. The shaped bodies are used for transporting, packaging, storing and handling foods and are characterized by reduced abrasion and an increased abrasion resistance. The quality of the foods that come into contact with such shaped bodies is excellent.
Claims15
Food-compatible flat-shaped bodies or shaped bodies or shaped bodies made from flat-shaped bodies, such as woven and non-woven materials, knits, multiaxial layers, spiral cloths or spiral sieves, pin wires, flat-shaped structures, such as grids, net-shaped flat structures, or shaped bodies made from these flat-shaped bodies, such as sacks, bags, nets, sieves, filters, transport belts, containing monofilaments based on polyester that contain 0.5 to 3.5 percent by weight of a polycarbonate.
A food-compatible monofilament based on polyester containing 0.5 to 3.5 percent by weight of a polycarbonate.
A method for producing flat-shaped bodies or shaped bodies or shaped bodies made from flat-shaped bodies, such as woven and non-woven materials, knits, multiaxial layers, spiral cloths or spiral sieves, pin wires, flat-shaped structures, such as grids, net-shaped flat structures, or shaped bodies made from these flat-shaped bodies, such as nets, sacks, bags, sieves, filters, for transporting, packaging, storing and treating foods by melt spinning polyester with the addition of 0.5 to 3.5 percent by weight of a polycarbonate in a molten mass by extrusion into monofilaments, and by processing the monofilaments into flat-shaped bodies, such as woven materials, looped materials, nets, and making the flat-shaped bodies, if required, into sacks, bags, filters, transport belts.
