Method for preparing graphene/nylon-6 fiber
11339505 · 2022-05-24 ·

A high-strength high-modulus graphene/nylon-6 fiber and a preparation method thereof are provided. The fiber is obtained through processing modified graphene and caprolactam with in situ polymerization and high-speed melt spinning. A graphene/nylon-6 composite is provided, which is obtained through compositing the modified graphene, the caprolactam and an additive. Based on the composite, a graphene/nylon-6 fabric with a permanent far-infrared healthcare function and a graphene/nylon-6 fabric with an ultraviolet protective property are provided, whose far-infrared property and ultraviolet protective property will not be attenuated due to an increase of fabric washing times, having a great market potential.

The present disclosure generally pertains to green oxidizer compositions and method of synthesizing and using the same. Such green oxidizers are stable, may be used in conventional bipropellant thrusters, including, but not limited to LDACS applications, and offer several benefits over conventional oxidizers with respect to toxicity and/or corrosion. The present disclosure also relates to methods of synthesizing poly-nitrated oxetane, a green oxidizer, in an Argon-rich environment.

Selective abrading of a surface of a woven textile fabric with proliferated thread count based on simultaneous insertion within a single pick insertion event of a loom apparatus multiple adjacent parallel yarns drawn from a multi-pick yarn package
11168414 · 2021-11-09 ·

A method includes drawing each multiple partially oriented polyester yarn from a corresponding supply package to form an oriented polyester yarn as a single multi-filament polyester weft yarn, inserting the multi-filament polyester weft yarn during a single pick insertion event of a pick insertion apparatus of a loom apparatus through winding the multi-filament polyester weft yarn on a single-pick yarn package, and conveying at least two of the multi-filament polyester weft yarn across a warp shed of the loom apparatus through a set of warp yarns in the single pick insertion event to form an incremental length of a woven textile fabric having a first surface with a majority of ends of the warp yarns and a second surface with a majority of picks of the multi-filament polyester weft yarn thereon. The method also includes solely abrading the second surface to provide for comfort to a user during contact therewith.

Sorbent and devices for capturing, stabilizing and recovering volatile and semi-volatile compounds
