Abstract
A fibrous assembly includes two components. The first component provides a visual indication of when a pre-determined tensile load is applied to the assembly or when the fibres of the assembly have been over-extended. The first and second components are movable relative to each other, the visual indication being provided by the first component being substantially concealed by the second component and becoming at least partially exposed when the pre-determined tensile load is applied to the assembly or when the fibres have been over-extended. The first component comprises auxetic yarn.
Claims20
A fibrous assembly comprising at least a first component and a second component wherein the first component provides a visual indication of when at least a pre-determined tensile load is applied to the assembly or when the fibres of the assembly have been over-extended, the first and second components being movable relative to each other, the visual indication being provided by the first component being substantially concealed by the second component and becoming at least partially exposed when the at least predetermined tensile load is applied to the assembly or when the fibres have been over-extended, wherein the first component comprises auxetic yarn.
A rope, belt, harness, bandage, restraint, sail, strappings or geotextile comprising a fibrous assembly, said fibrous assembly comprising at least a first component and a second component wherein the first component provides a visual indication of when at least a pre-determined tensile load is applied to the assembly or when the fibres of the assembly have been over-extended, the first and second components being movable relative to each other, the visual indication being provided by the first component being substantially concealed by the second component and becoming at least partially exposed when the at least predetermined tensile load is applied to the assembly or when the fibres have been over-extended, wherein the first component comprises auxetic yarn.
A lifting device for a tensile load comprising a fibrous assembly, said fibrous assembly comprising at least a first component and a second component wherein the first component provides a visual indication of when at least a pre-determined tensile load is applied to the assembly or when the fibres of the assembly have been over-extended, the first and second components being movable relative to each other, the visual indication being provided by the first component being substantially concealed by the second component and becoming at least partially exposed when the at least predetermined tensile load is applied to the assembly or when the fibres have been over-extended, wherein the first component comprises auxetic yarn.
A method of manufacturing a fibrous assembly, comprising the steps of:
- i) providing at least a first component and a second component, wherein the first component provides a visual indication of when at least a pre-determined tensile load is applied to the assembly or when the fibres of the assembly have been over-extended, and wherein the first component comprises auxetic yarn;
- and
- ii) combining the first component with the second component so that the first component is substantially concealed by the second component, and so that the first and second components are movable relative to each other, the visual indication being provided by the first component being substantially concealed by the second component and becoming at least partially exposed when the at least predetermined tensile load is applied to the assembly or when the fibres have been over-extended.
