The invention provides electronic beam cured paper packaging gloss oil and a curing method of a printed coating. The electronic beam cured gloss oil comprises unsaturated acrylate, polyfunctional acrylate monomers, monofunctional acrylate monomers and extinction additive components. The electron beam curing gloss oil is obtained by uniformly mixing the unsaturated acrylate, polyfunctional acrylatemonomers, monofunctional acrylate monomers and extinction additive components. The function of the electron beam curing gloss oil is to protect an ink layer, and the electron beam curing gloss oil does not contain photoinitiators, so that a printing sample after the the electron beam curing gloss oil is cured does not contain photoinitiators, and the harm of the printed coating on human health isavoided. In addition, an electron accelerator irradiation curing process has no influence on color, and the curing at normal temperature can ensure that a printed stock is not deformed during the processing.

The invention provides a brand novel weaving concept of chemical synthetic fibers and a method thereof. Copper ammonia fibres, paraffin, carbon black powder, etc. are used as raw materials; the fibers spinning by dissolution method such as nitrilon, copper ammonia fibres, vinylon, etc. are used; single hole spinning is changed into compound spinning by spinning parts with a sheath-core structure when the spinning is non-compound spinning, which can obviously improve weaving performance; the outer layer of the spinning uses water-soluble paraffin and the surface of the fibers reserves concave-convex appearance caused by atoms at the same time when the paraffin is removed. The invention does not influence fiber color and has low cost and strong weaving capacity.
