Abstract
This invention relates to an article of thermal protective clothing having fabric woven with a warp-faced or weft-faced twill weave that incorporates a first yarn forming the majority of the outer article surface that includes hydrophilic fiber and a first flame resistant fiber, with at least 25 weight percent of that first yarn being hydrophilic fiber; and a second yarn forming the majority of the inner article surface that includes at least 80 weight percent of a second flame resistant fiber that is hydrophobic. Alternatively, the first yarn forming the majority of the outer article surface can include a hydrophilic first flame resistant fiber.
Claims15
An article of thermal protective clothing comprising woven fabric having a warp yarn dissimilar to a fill yarn, the fabric forming an inner and outer surface of the article;
- the fabric further having a warp-faced or weft-faced twill weave, wherein either:
- a) a majority of the outer surface of the article is a first yarn that is the warp yarn in the fabric and a majority of the inner surface of the article is a second yarn that is the fill yarn in the fabric, or
- b) a majority of the outer surface of the article is a first yarn that is a fill yarn in the fabric and a majority of the inner surface of the article is a second yarn that is the warp yarn in the fabric;
- and
- wherein the first yarn forming the majority of the outer surface of the article comprises hydrophilic fiber and a first flame resistant fiber, with at least 25 weight percent of the yarn being hydrophilic fiber;
- and
- wherein the second yarn forming the majority of the inner surface of the article comprises at least 80 weight percent of a second flame resistant fiber that is hydrophobic,
- wherein the wetting time on the inner surface is less than 6 seconds and the wetting time for the outer surface is at least 6 seconds or greater.
An article of thermal protective clothing comprising woven fabric having a warp yarn dissimilar to a fill yarn, the fabric forming an inner and outer surface of the article;
- the fabric further having a warp-faced or weft-faced twill weave, wherein either:
- a) a majority of the outer surface of the article is a first yarn that is the warp yarn in the fabric and a majority of the inner surface of the article is a second yarn that is the fill yarn in the fabric, or
- b) a majority of the outer surface of the article is a first yarn that is a fill yarn in the fabric and a majority of the inner surface of the article is a second yarn that is the warp yarn in the fabric;
- and
- wherein the first yarn forming the majority of the outer surface of the article comprises at least 25 percent by weight a hydrophilic first flame resistant fiber;
- and
- wherein the second yarn forming the majority of the inner surface of the article comprises at least 80 weight percent of a second flame resistant fiber that is hydrophobic,
- wherein the wetting time on the inner surface is less than 6 seconds and the wetting time for the outer surface is at least 6 seconds or greater.
A coverall, shirt, or pants article made from a single layer of the warp-faced twill weave fabric, the fabric having a warp yarn dissimilar to a fill yarn, the fabric forming an inner and outer surface of the article;
- and wherein either:
- a) a majority of the outer surface of the article is a first yarn that is the warp yarn in the fabric and a majority of the inner surface of the article is a second yarn that is the fill yarn in the fabric, or
- b) a majority of the outer surface of the article is a first yarn that is a fill yarn in the fabric and a majority of the inner surface of the article is a second yarn that is the warp yarn in the fabric;
- and
- wherein the first yarn forming the majority of the outer surface of the article comprises either:
- i) hydrophilic fiber and a first flame resistant fiber, with at least 25 weight percent of the yarn being hydrophilic fiber, or
- ii) at least 25 percent by weight a hydrophilic first flame resistant fiber;
- and
- wherein the second yarn forming the majority of the inner surface of the article comprises at least 80 weight percent of a second flame resistant fiber that is hydrophobic,
- wherein the wetting time on the inner surface is less than 6 seconds and the wetting time for the outer surface is at least 6 seconds or greater.
