Process for manufacturing disposable absorbent articles
Abstract
A production line for manufacturing disposable absorbent articles from bulk starting polymeric materials including virgin and on-line recycled polymeric materials. The production line includes a continuous process that links the steps of forming the webs with the steps of converting the webs into disposable absorbent articles. The production line recycles non-woven materials produced on the production line back into the production process of producing disposable absorbent articles. The recycling operations can also include a spun-bonded recycling and a melt-blown recycling. The production line can be a single-product-lane operation or a multiple-product-lane operation.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A method for recycling continuous fibers exiting one or more spun-bonded modules, the method comprising the steps of:
(a) providing at least one spun-bonded module; (b) diverging the continuous fibers exiting the spun-bonded module into a recycling operation by a gust of a compressed fluid; (c) disintegrating the continuous fibers in the recycling operation; (d) conveying the disintegrated fibers into a recycling station; and (e) recycling the disintegrated fibers into a recycled polymeric material.
2 . The method of claim 1 used in the manufacture of disposable absorbent articles.
3 . A method for recycling a molten polymeric material exiting a spinneret of a melt-blown module back in the melt-blown module, the method comprising the steps of:
i. providing the melt-blown module extruding the molten material; ii. providing a collecting die for collecting the molten polymeric material from the spinneret; iii. providing a conduit being in communication with the collecting die for transporting the molten polymeric material; iv. collecting the molten polymeric material exiting the spinneret by the collecting die; and v. transporting the molten polymeric material by the conduit from the collecting die to a metering pump of the melt-blown module for re-extruding the molten polymeric material through the spinneret.
4 . The method of claim 3 used in the manufacture of disposable absorbent articles.Join the waitlist — get patent alerts
