METHOD FOR PRODUCING OF DOUBLED CARPET COVERING "ECOFLOOR" Russian patent published in 2005 - IPC

FIELD: textile industry, in particular, manufacture of formed articles of car saloon.

SUBSTANCE: method involves manufacturing face side in the form of needle-stitched structured web; manufacturing reverse side in the form of needle-stitched web and doubling resultant webs. Web is structured on needle stitching machine by means of stitching needles equipped with notches, which entrain fibers upon passage through web and pull to predetermined depth into brush conveyor where pile is formed. Manufacturing of needle-stitched web involves preparing of fibrous mixture; forming cloth; transformation of cloth and securing of cloth. Fibrous mixture is prepared in mellowing and mixing unit, where fiber mellowing and mixing processes are provided, with following forming of fibrous cloth from ready fibrous mixture. Cloth is then delivered to combing converter adapted for producing of multilayer fibrous cloth with randomly arranged fibers. Cloth is then delivered by means of discharge conveyor to needle stitching machine for converting thereof into web. Doubling is provided by stitching together of needle-stitched web and needle-stitched structured web by means of stitching needles or by means of thermal adhesive(s) during forming of parts.

EFFECT: improved ecology control owing to the use of biocomponent low melting point fibers, various production wastes without use of binders, such as polymeric dispersions.
