A light weight tear resistant fabric having a background fabric and reinforcing yarns selected such that the tensile strength of the reinforcing yarn is about two times that of the yarns of the background fabric and the elongation of the reinforcing yarns is at least two times that of the background fabric is described. The resulting reinforced fabric has at least 50% greater tear resistance than the background fabric as measured by the Elmendorf test.

Light weight tear resistant fabric

Heat flow through a protective garment is reduced if the shell is a woven fabric extends laterally and expands away from the wearer upon exposure to a high heat flux.

Protective garments comprising an outer shell fabric of woven aramid

A reinforced fabric composed of a background fabric and a reinforcing grid that is joined to the background fabric so that the grid reinforced fabric is at least 20% stronger than a fabric into which reinforcing yarns of the same type and weight percent as that of the grid have been integrally woven.

Reinforced fabric

A method for forming a slub yarn uses conventional false-twist texturing apparatus in combination with one or more air jets to impart striations and/or neps and slubs to continuous filament yarns. Three process configurations are disclosed; each configuration uses one air jet through which yarn passes and which directs turbulent air in a direction opposite to the direction of travel of the yarn.
