  • Patent number: 11144891
    Abstract: A closed-loop system for the utilization of recycled woven and/or non-woven polyester fabric products in a plurality of high occupancy facilities includes at least one manufacturing facility to produce a plurality of recycled polyester fabric products from a recycled polyester fabric feedstock. A distribution network transports the plurality of recycled polyester fabric products to each of the plurality of high occupancy facilities, and a housekeeping network distributes and arranges recycled polyester fabric products in a plurality of rooms in a corresponding high occupancy facility. A collection network transports a plurality of compacted polyester fabric products from each of the plurality of high occupancy facilities back to the manufacturing facility. A corresponding closed-loop method for implementing the aforementioned closed-loop system is also disclosed.

  • Publication number: 20180274143
    Abstract: A nonwoven recyclable fabric and associated methods are provided. The fabric is formed from 100% polyester, and may also include surface coatings such as hydrophilic coatings to promote heat transfer as well moisture vapor transmission rates and/or a silicone coating to promote fabric smoothness and reduce abrasiveness of the fabric. The polyester fibers forming the fabric are obtained from a mixture of monocomponent high melt polyester fibers and bicomponent high/low melt polyester fibers. The bicomponent fibers have a high melt polyester core, and a low melt polyester outer sheath. The fibers are hydroentangled with one another. After entanglement, the low melt outer sheaths are melted to form a low melt binder interspersed with the high melt polyester fibers and the remaining high melt polyester cores. The binder fuses to these fibers to provide desirable strength characteristics.
