NOVELTY - Method for manufacturing controlled release polymer fabrics, involves performing extrusion of active ingredients into master batches in the form of granules with copolymer additives, (b) mixing of active ingredient granules with high density polyethylene (HDPE), linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE) or polypropylene, (c) performing extrusion of filaments and incorporation of filaments with active ingredients and (d) combining two or more impregnated or incorporated filaments or yarns to produce a wash durable insecticidal fabrics.    USE - The method is useful for manufacturing controlled release polymer fabrics, which is useful for controlling pest, preferably resistant strains of household pest, more preferably roaches, ants, termites, ticks, sand fly, silver fish, house fly, mosquitoes, and spider.    ADVANTAGE - The method is highly safe and environmentally-friendly as it eliminates repeated spraying of pesticides containing hazardous chemicals, and enables to reduce the processing temperature and thus prevents the thermal degradation and wastage of active ingredients. The product has long-lasting shelf life and excellent wash durability and enables to prevent vector-borne diseases, preferably malaria, leishmaniasis, trypanosomiasis, Chagas disease, lymphatic filariasis, onchocerciasis, dengue, yellow fever and encephalitis.    DETAILED DESCRIPTION - Method for manufacturing controlled release polymer fabrics, involves performing extrusion of active ingredients into master batches in the form of granules with copolymer additives, (b) mixing of active ingredient granules obtained in step (a) with high density polyethylene (HDPE), linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE) or polypropylene, (c) performing extrusion of filaments at 120-250 degrees C and incorporation of filaments with active ingredients and (d) combining two or more impregnated or incorporated filaments or yarns to produce a wash durable insecticidal fabrics, where the filaments includes monofilaments, multifilament, tape yarns and fibers, the active ingredients are infused or incorporated into the filament using the process of extrusion, the copolymer additives comprises acidic group and do not migrate to the surface, the copolymer additive enhance the retention index of the active ingredient in the polymer, and helps to reduce the temperature during extrusion process, the impregnation occurs within the fiber and only a small fraction of active ingredients diffuse from the filament core to the surface of the fiber, and the at least one active ingredient is used for a single yarn and several yarns having several active ingredients or several class of chemicals are woven or non-woven or knitted together in the fabric and each active ingredient is released independently without interference from the other. An INDEPENDENT CLAIM is included for controlled release polymer fabric comprises active ingredient incorporated polymer filaments having high wash durability, where the active ingredients are chosen from fipronil, bifenthrin, delta methirn, alpha -cypermethrin and their combination, preferably fipronil and bifenthrin, and the combination of yarns having coating of fipronil and yarns having coating of bifenthrin are woven or non-woven or knitted together to form the fabric and the coating of active ingredients is achieved by above method.
