METHOD TO RECYCLE POLYESTER-BASED NONWOVEN TO STAPLE FIBER

Contrary to packagings or bottles made of pure materials like PET, nonwovens usually consist of a mix of materials and are as such difficult to include in a recycling process. The present invention relates to a method for recycling polyester-based nonwovens comprising 5 to 50% of PET/coPET low melt staple fibers into polyester staple fibers (PSF), and further including these fibers into new nonwovens for a large variety of articles for applications in virtually any technical field.

STITCH BONDED CLEANING PAD WITH VARIABLE HEIGHT LOOP ELEMENTS
20240183093 · 2024-06-06 ·

A disposable cleaning pad of stitch-bonded construction adapted to be affixed to a mop head for manipulation across a surface to be cleaned. The cleaning pad includes a sorbent stitching substrate of fleece in layered relation with at least one support layer. A first yarn feed and a second yarn feed are in stitched relation through a stitched portion of the stitching substrate. The first yam feed forms a first loop collection, and the second yarn feed forms a second loop collection. The second loop collection covers a smaller area than the first loop collection and defines a predefined pattern within the stitched portion of the stitching substrate. The second loop collection has an average pile height greater than the first loop collection.

METHODS, SYSTEMS, AND DEVICES FOR GENERATING DEFINED FIBER CONSTRUCTS

Systems, devices, and methods for generating fiber constructs via electrospinning are disclosed herein. The system for generating fiber constructs includes an ejection device and a collector. The collector contains a collection surface with patterns formed by conductive trace(s). The conductive trace(s) is arranged such that the resulting electric field lines are either undisturbed electrostatic field lines or blurred electrostatic field lines aligned around each conductive trace. Methods of generating fiber constructs using the system via electrospinning includes applying an electrostatic charge to the ejection device or a component thereof. The formed fiber construct has a grammage that is at least 5% higher than a grammage of a fiber construct formed on an un-patterned collector under the same conditions. The electrospun fiber constructs may be used for forming engineered tissues or implants, wound dressings, drug delivery formulations, and implant or device coatings.
