Benefits of technology

This patent is about a special textile fabric that is resistant to fire. The fabric has a coating that includes a combination of expandable graphite and nanoclay. The expandable graphite particles are small and have a specific range of particle sizes. The coating also includes a latex binder. The fabric is made of woven materials and is useful for protecting firefighters and other personnel who need to wear flame resistant clothing.

Problems solved by technology

Each year, thousands of residential fires are caused in the United States by the ignition of mattresses and bedding, resulting in hundreds of deaths and hundreds of millions of dollars in property losses.

example

[0031]Samples of a non-woven textile were coated with one of two coatings (i.e., Coating 1 and Coating 2) by a foam coating process. Coating 1 was an aqueous suspension having roughly 50% solids by weight, including a pigment, about 5% acrylic latex by weight as a binder, and auxiliary chemistry. Coating 2 had the same composition as Coating 1, except that it included about 10% bentonite (CLOISITE NA+, BYK Additives, Inc., Gonzales, Tex.) by weight. The coatings were applied to a stitch-bonded, non-woven blend of silica-filled FR rayon fibers (65%) and polyester fibers (35%).

[0032]The thermal transfer and shrinkage of the coated fabrics were tested using a vertical-burn test. FIG. 6 is a photographic image of the test apparatus 48 used to conduct the vertical burn test. FIG. 7 is a photographic image of a test sample 50 of a fabric mounted on a sample frame 52 of the test apparatus 48 of FIG. 6. FIG. 8 is a view of a vertical burn test of the test sample 50, wherein the flame 54 is ...

Abstract

A flame resistant textile fabric includes a coating having an expandable graphite, or a combination of an expandable graphite and a nanoclay, disposed on one or both of its first and second surfaces. The flame resistant textile fabrics may be used to make one or more components of a mattress, such as a filler cloth, or fabric fire barrier.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a Section 111(a) application relating to and claiming the benefit of U.S. Provisional Patent Application No. 62 / 473,774, filed on Mar. 20, 2017, which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to the field of flame-resistant fabrics, and, more specifically, to enhancements for improving the flame resistance of such fabrics and the flame resistance of items incorporating such fabrics.BACKGROUND OF THE INVENTION[0003]Each year, thousands of residential fires are caused in the United States by the ignition of mattresses and bedding, resulting in hundreds of deaths and hundreds of millions of dollars in property losses. Heightened awareness of fire prevention has led to the development of standards and regulations directed to reducing the likelihood that such fires will occur. One approach to reducing the likelihood of residential fires is to use flame-res...
