Problems solved by technology

Fabrics and garments comprising flame resistant fibers of low tensile strength when exposed to the intense thermal stress of an electrical arc can break open exposing the wearer to additional injury as a result of the incident energy.
Currently cotton or cotton/Nylon 66 fabric treated with flame retardant solutions is commercially available,

Example

[0032]All materials used herein were commercially purchased as described herein or prepared from commercially purchased materials as described herein.

[0033]Described herein are light weight flame retardant, electrical arc and flash fire protecting yarns / fabrics / garments comprising several aesthetic properties of denim. The flame resistance properties are retained even after different types of denim washes such as enzyme wash, stone wash, oxidation, tint wash and the like. The yarns or fabrics, and garments thereof described herein also comprise antistatic properties and are breathable (air permeable, moisture / vapor permeable) which helps reduce perspiration thereby providing greater comfort to the user for longer periods of time.

[0034]Provided herein are yarns, fabrics and garments which, when exposed to the intense thermal stress of an electrical arc resist the transfer of energy, reduce energy transfer by absorbing a portion of the incident energy and, through charring, allow a re...

Abstract

Provided herein are blended fibers for use in protective clothing which confer protection against electrical arcs and/or flash fire hazards and also have a pleasing appearance, while also being comfortable to wear. The fabrics described herein can be processed to give an aesthetically desired appearance such as a washed denim look.

Description

FIELD OF INVENTION[0001]This disclosure is related to wearable protection fabrics which confer protection against, inter alia, electrical arcs and / or flash fires.BACKGROUND OF THE INVENTION[0002]Fabrics and garments comprising flame resistant fibers of low tensile strength when exposed to the intense thermal stress of an electrical arc can break open exposing the wearer to additional injury as a result of the incident energy. Electrical arcs typically involve thousands of volts and thousands of amperes of electrical current. The electrical arc is much more intense than incident energy such as from a flash fire. To offer protection against electrical arcs to a wearer of a garment or fabric, the garment of fabric must resist the transfer of energy through the fabric or garment to the wearer. It is believed that this occurs both by the fabric absorbing a portion of the incident energy and by the fabric resisting break open. During break open a hole forms in the fabric directly exposing...
