Abstract
A unique formulation for yarn from a novel combination of fibers of polyester and silver which is made by a special manufacturing process including proprietary individual steps. The formed yarn product is durable and useful and can be used to make various fabrics and/or materials and, most particularly, to make final products that possess highly advanced characteristics, particularly fire retardant properties and antimicrobial properties.
Claims17
A process for making yarn having enhanced strength, stability and antimicrobial properties comprising:
- A. providing a polyester staple of polyester fibers all having a uniform fiber length of between 30 mm and 60 mm approximately;
- B. providing a silver staple of silver fibers;
- C. cutting the silver fibers of the silver staple to a uniform fiber length of between 30 mm and 60 mm approximately;
- D. forming a fibrous staple compound containing approximately 94% polyester fibers and approximately 6% silver fiber as measured by weight;
- E. primary mixing of the fibrous staple compound;
- F. coating of the fibrous staple compound with a liquid ceramic material;
- G. secondary mixing of the fibrous staple compound;
- H. dividing of the fibrous staple compound into individual batches of fibrous staple compound;
- I. blending of each of the individual batches of fibrous staple compound in order to further open the fibrous material located therewithin for facilitating more homogenous mixing of the individual fibrous components of the fibrous staple compound;
- and
- J. spinning the blended fibrous staple compound for tightening thereof into sliver form of the fibrous staple compound;
- K. tightening of the sliver form of the fibrous staple compound into a roving form of the fibrous staple compound;
- L. placing of the roving form of the fibrous staple compound onto roving spools;
- M. spinning of the roving form of the fibrous compound into yarn;
- N. winding of the yarn onto cones while applying of a mixture of paraffin and ceramic wax thereon for lubrication thereof and to facilitate stabilizing thereof;
- and
- O. heating of the yarn sufficiently to stabilize the yarn and to molecularly bond the ceramic material thereto for chemically retaining and further bonding together of the various fibers contained within the yarn.

- F. primary mixing of the fibrous staple compound mechanically and manually;
- G. coating of the fibrous staple compound with a liquid ceramic material wherein said coating of the fibrous staple compound with a liquid ceramic material is performed by spraying of a translucent liquid ceramic material thereupon;
- H. secondary mixing of the fibrous staple compound mechanically and manually;
- I. dividing of the fibrous staple compound into individual batches of fibrous staple compound each having a weight of approximately 20 pounds to 100 pounds;
- J. blending of each of the individual batches of fibrous staple compound in a textile carding machine a plurality of separate times in order to further open the fibrous material located therewithin for facilitating more homogenous mixing of the individual fibrous components of the fibrous staple compound;
- and
- K. spinning the blended fibrous staple compound using a spinning frame for tightening thereof into sliver form of the fibrous staple compound;
- L. tightening of the sliver form of the fibrous staple compound into a roving form of the fibrous staple compound;
- M. placing of the roving form of the fibrous staple compound onto roving spools;
- N. spinning of the roving form of the fibrous compound into yarn;
- O. winding of the yarn onto cones while applying of a mixture of paraffin and ceramic wax thereon for lubrication thereof and to facilitate stabilizing thereof;
- and
- P. steam heating of the yarn to approximately 180 degrees Fahrenheit to stabilize the yarn and to molecularly bond the ceramic material thereto for chemically retaining and further bonding together of the various fibers contained within the yarn.
