Abstract
A composite heat resistant sewing thread comprising a core form of at least one strand of a yarn having an elongation, at least one bottom cover wrapped around the core in a first direction at a rate sufficient to provide substantially complete coverage of the core, at least one outer cover wrapped around the at least one bottom cover, at least one bonding agent, and a lubricant.
Claims52
A composite heat resistant sewing thread comprising:
- a) a core formed of at least one strand of a yarn having an elongation of at least 3%;
- b) at least one bottom cover wrapped around the core in a first direction at a rate sufficient to provide substantially complete coverage of the core by the bottom cover, wherein the bottom cover has an elongation of less than 1% and is made of a high-tenacity yarn;
- c) at least one outer cover wrapped around the at least one bottom cover, wherein the outer cover is wrapped in a second direction opposite to a direction of a cover layer on which the outer cover is directly wrapped, at a rate sufficient to provide substantially complete cover of the cover layer on which the outer cover is directly wrapped;
- d) at least one bonding agent applied onto the at least one outer cover;
- and
- e) a lubricant;
- wherein the composite heat resistant sewing thread remains intact when subjected to temperatures exceeding 1,000° C.
A fire and heat resistant mattress comprising a flammable body section covered with a fire resistant cover, wherein seams of the fire resistant cover are sewed together with a composite sewing thread comprising:
- a) a core formed of at least one strand of a yarn having an elongation of at least 3%;
- b) at least one bottom cover wrapped around the core in a first direction at a rate sufficient to provide substantially complete coverage of the core by the bottom cover, wherein the bottom cover has an elongation of less than 1% and is made of a high-tenacity yarn;
- c) at least one outer cover wrapped around the at least one bottom cover, wherein the outer cover is wrapped in a second direction opposite to a direction of a cover layer on which the outer cover is directly wrapped, at a rate sufficient to provide substantially complete cover of the cover layer on which the outer cover is directly wrapped;
- d) at least one bonding agent;
- and
- e) a lubricant;
- wherein the composite heat resistant sewing thread remains intact when subjected to temperatures exceeding 1,000° C.
A pillow comprising a body portion covered by a fire resistant fabric covering with one or more seams, wherein the one or more seams are sewed together with a composite sewing thread comprising:
- a) a core formed of at least one strand of a yarn having an elongation of at least 3%;
- b) at least one bottom cover wrapped around the core in a first direction at a rate sufficient to provide substantially complete coverage of the core by the bottom cover, wherein the bottom cover has an elongation of less than 1% and is made of a high-tenacity yarn;
- c) at least one outer cover wrapped around the at least one bottom cover, wherein the outer cover is wrapped in a second direction opposite to a direction of a cover layer on which the outer cover is directly wrapped, at a rate sufficient to provide substantially complete cover of the cover layer on which the outer cover is directly wrapped;
- d) at least one bonding agent;
- and
- e) a lubricant;
- wherein the composite heat resistant sewing thread remains intact when subjected to temperatures exceeding 1,000° C.
A fire resistant item of apparel comprising one or more fabric sections formed of fire resistant material and sewn along one or more seams, the seams between said fabric sections being sewed together by a composite heat resistant sewing thread comprising:
- a) a core formed of at least one strand of a yarn having an elongation of at least 3%;
- b) at least one bottom cover wrapped around the core in a first direction at a rate sufficient to provide substantially complete coverage of the core by the bottom cover, wherein the bottom cover has an elongation of less than 1% and is made of a high-tenacity yarn;
- c) at least one outer cover wrapped around the at least one bottom cover, wherein the outer cover is wrapped in a second direction opposite to a direction of a cover layer on which the outer cover is directly wrapped, at a rate sufficient to provide substantially complete cover of the cover layer on which the outer cover is directly wrapped;
- d) at least one bonding agent;
- and
- e) a lubricant;
- wherein the composite heat resistant sewing thread remains intact when subjected to temperatures exceeding 1,000° C.
